The difference between stainless steel grease traps and traditional grease traps

Clause. First, the traditional grease trap uses only the difference in the density difference of oil compared with water. The stainless steel grease trap adopts the principle of oil-water specific gravity difference, inclined plate sedimentation, coalescence principle, etc., which greatly improves the efficiency of oil-water separation.

Clause. Second, the traditional grease trap oil discharge must be manually oiled, not only improve the cost of manual maintenance, but also manual oil fishing is a very troublesome thing, oily sewage is very dirty and smelly, criminals take the opportunity to fish out "gutter oil" to endanger human life and health. And stainless steel grease traps are different:

The fully enclosed design can be used to drain the oil by opening the oil drain valve, which eliminates the tragedy of "gutter oil" returning to the table.

Clause. 3. The traditional grease trap generally cannot be separated from oil and water, because the position of the oil drain valve is fixed, and the oil-water interface is unstable when the water is inlet into the water inlet, and the oil discharge is also unstable when the oil drain valve is opened. The stainless steel grease trap is designed to change the water inlet mode to the upper water inlet mode, and the separation box adopts an inclined plane, which greatly improves the effect of oil-water separation.

Clause. Fourth, the grease trap should be fished out every day, and the smell is unpleasant when opened, and the stainless steel grease trap can be closed and odorless in use.

Extension of knowledge points:

The stainless steel grease trap is to use the different specific gravity of suspended solids and water in wastewater to achieve the purpose of separation.

The structure of the stainless steel grease trap mostly adopts advection, and the oily wastewater enters the grease trap with a rectangular plane through the water distribution tank, flows slowly along the horizontal direction, floats on the surface of the oil product in the flow, and is pushed into the oil collection pipe by the oil collection pipe or the oil scraper arranged on the pool surface and flows into the dewatering tank.

Nowadays, many companies and enterprises use stainless steel grease traps, which are simple to install, small in size, and easy to maintain and clean up compared with traditional grease traps. The oil-water separator of Jinyuyuan is mainly stainless steel, if it is the transformation of the grease trap, it can be transformed on the basis of the traditional cement grease trap, but the staff needs to install the pipeline of the grease separation and deodorization equipment to achieve the effect of degrading grease.

The results that have been found for you: the difference between the primary grease trap and the secondary grease trap is that their treatment effects and treatment principles are different. Primary grease traps are mainly used to separate large particles and oil stains, while secondary grease traps are more focused on handling fine oil particles.

A primary grease trap is usually the first treatment piece of the wastewater treatment system and is used to separate large particles and oil from the sewage. When the dirty dust water passes through the primary grease trap, the oil will float on the surface of the water to form a layer of oil slick, and the large particles will settle to the bottom of the tank. This can effectively reduce the load of the follow-up treatment equipment, and can also prevent the damage of oil pollution and large particles to the downstream equipment.

The secondary grease trap is based on the primary grease trap to further treat the oil in the sewage. When the sewage passes through the secondary grease trap, it will go through a series of filtration and separation, making the oil in the sewage more pure. Secondary grease traps typically use finer filter media and more advanced separation techniques to handle some of the fine oil particles that a silver sail grease trap can't handle.

Hello, I am happy to answer for you, for you to inquire the results, the primary grease trap and the secondary grease trap are used to treat the oil in the wastewater spine inspection, but their differences are: 1Processing Effect:

The primary grease trap is mainly used for the preliminary filtration and separation of large particles of oil in wastewater, which can remove oil stains with a diameter greater than mm of cherry tomato; The secondary grease trap further treats the small particles of oil in the wastewater, which can remove oil stains with a diameter greater than a millimeter. 2.Equipment structure:

The structure of the secondary grease trap is relatively complex, usually including multiple parts such as sedimentation tank, filter, oil-water separator, etc., while the primary grease trap is relatively simple, usually with only one sedimentation tank. 3.Applications:

Oil-water separator.

It is a device that solves the discharge of oily sewage in the kitchen.

Oily wastewater is discharged in large quantities, and such a discharge will cause great damage to water resources.

The quality of the oily effluent discharged into the pipes every day by the kitchen is very high, so the water quality is very polluting. It is also a kind of harm to the drain pipe, as soon as the grease solidifies in winter, it will cause the blockage of the drain pipe, and then the kitchen will also produce a lot of odors, so there is a catering grease trap this equipment, which can well separate food residues, waste oil, and wastewater. The treated oily effluent is discharged without causing any damage to our water resources.

Grease traps are generally designed to keep grease out of the treatment system. If it enters the system, it is a question whether one of the microorganisms can be consumed and disposed of, and the other oil may be toxic to microorganisms.

Oil pollution is more serious, which has an obstructive effect on dissolved oxygen in the water, and also hinders the entry of oxygen into the soil, which will affect the drainage pipes of the city and the drainage equipment.

Because oil is not good for biological treatment systems, it can also have an impact on pipelines.

First, the oil is separated by physical methods to reduce the pressure of biochemical treatment.

Oil is harmful to the ecology of water bodies and will block pipelines.

Reduce the load on the subsequent reaction cell

To put it simply, the grease trap is a treatment structure that uses the characteristics of different specific gravity and complementary compatibility of oil and water to separate and remove the suspended oil with large particles in the sewage. Note that it is a large particle of suspended oil, and there are also emulsified oils, dissolved oils, etc., and the effect of grease traps is not good.

The function of the grease trap is to pre-treat the sewage discharged into the pipe network and remove most of the oil slick from the water.

The grease trap is a device for separating oil and water, which is generally used to clean the grease trap of the kitchen drain pipe of various hotels, restaurants, high-end guest houses and commercial restaurants.

1. Remove the oil slick to prevent scaling in the pipeline and reduce the short surface of the pipeline. 2. Preliminary anaerobic treatment to reduce effluent COD

The choice of grease trap is estimated according to the diner, and the calculation method of the current reputation source is as follows:

Know the number of diners and the type of meal.

qh1= nq0khksγ/1000t

Know the size of the restaurant and the type of meal.

QH2= QH1, QH2 in SQ0KKS SS1000T formula - hourly treated water volume (m3 h);

n – the number of diners in the restaurant (people).

t - duration of the meal;

s - usable area of restaurants and dining halls (m2);

SS - The minimum usable area (m2) of each seat in restaurants and dining halls is simply based on 100 people and the water output is calculated according to 1L s.

We all know that the discharge of kitchen oil and sewage has always been a problem, it is impossible not to discharge, and it is even more impossible to discharge to the ditch, so there is a stainless steel oil separator equipment, with this oil separator, the oil and sewage through this equipment can meet the municipal discharge standards, so that you can discharge sewage with peace of mind!

1.From the material aspect: we all know that stainless steel is divided into a variety of materials, the quality of each material is not the same, we generally use 210 and 304 materials, you can choose according to the budget, service life.

2.From the aspect of use: try to choose more automated equipment, so that later maintenance and easy maintenance.

3.From the aspect of safety and hygiene: the equipment should be made of stainless steel as much as possible to avoid cutting corners, resulting in a short life cycle of the equipment, and it is necessary to install protection devices to automatically cut off water and electricity to prevent accidents.

4.From the cost aspect: stainless steel products of different materials, stainless steel products of different thicknesses are different, you must do your own budget in the early stage of purchasing equipment, including equipment costs, service fees, installation fees, transportation costs, taxes, etc., all need to be taken into account.

5.From the functional aspect: the purchase of equipment is necessary to buy according to their own needs, pay attention to the use of the equipment, whether it can meet their own needs, oil separator equipment has fully automatic, semi-automatic, hydraulic, buried, semi-buried, dishwasher, hoisting grease separator, etc., to avoid blind choice because of the lowest quality.

The catering industry generally requires the approval of 4 departments, the first is to apply for a unit name from the industry and commerce to prevent the duplication of the store name and the registered unit.

Then, the approval materials will be submitted to three pre-approval departments: fire protection, health supervision, and environmental protection.

The requirements of each department are briefly introduced, and the approval requirements of the department shall prevail.

The requirements of the fire department are to have 2 fire safety passages, fire extinguishers, etc.

Health department: how much area is the store, the cooked food area and raw food should be separated, and the three prevention facilities (fly-proof, dust-proof, rodent-proof) and so on.

Environmental protection department: the site should not be in a residential area, the upstairs should not be residential, there should be grease traps, chimneys should be high-altitude emissions, etc.

After the three pre-departments have been reviewed, the materials can be submitted to the industry and commerce.

Suggestion: After preliminarily determining the project address, first ask the landlord whether the fire protection has passed the acceptance; Ask about hygiene, whether the area is large enough; Ask about environmental protection, can you open it there, and introduce the project address; After getting a reply, rent it again, otherwise it will be a waste of money.

Don't be in a hurry to decorate, especially the way the kitchen, dining room, and bathroom are set up, and you should ask the hygienic people, and let them give some advice or ask experienced people if they don't know it, for example, if you can't build a bathroom next to the kitchen, you should reserve the location of the grease trap, and all the water in the restaurant (washing vegetables, washing dishes, and brushing pots, but excluding the bathroom) should be discharged to the municipal pipeline through the grease trap. The chimney should not affect the surrounding people, and environmental protection facilities should be installed to remove oil fumes.

The time for application varies from department to department, but it is estimated to be about a month. For specific service guidelines, environmental protection and health supervision, please go to the **** of your district to inquire, and you can find the link of each district **** under the city ****.

Fire protection and industry and commerce are vertical management agencies, and you go to the city's ** to see the administrative license or service guide. Each department has a date set, which can be seen online.

The function of the grease trap is to use the natural float method to separate and remove the floating oil substances in the oily wastewater. The grease trap can remove the petroleum substances in the floating and coarsely dispersed state with less density than the wastewater, and have almost no effect on the oil in the emulsified, dissolved and dispersed state.

Its basic requirements are as follows:

1) The grease trap must be equipped with both oil collection and sludge discharge measures.

2) The grease trap should be sealed or added with a movable cover plate to prevent oil and gas from polluting the environment and the occurrence of fire accidents, and at the same time can play the role of rain prevention and heat preservation.

3) Effective thermal insulation and cold-proof measures should be taken for grease traps in cold areas to prevent the solidification of dirty oil. In order to ensure the smooth flow of sludge oil, a heater with steam as the heat source can be set under the oil collection pipe and the sludge oil conveying pipe.

4) The grease trap should be designated as a fire ban area within a certain range, and equipped with sufficient fire-fighting equipment and other fire-fighting means. Steam is generally used for fire prevention in the grease trap, usually a circle of steam fire pipes is set along the pool wall 200mm below the top cover of the pool.

5) There should be steam pipeline joints in the area near the grease trap to connect the temporary steam to extinguish the fire, or clean up the pipeline or sewage oil when the temperature is low in winter due to the blockage of the pipeline caused by the solidification of the sewage oil or the sewage oil sticking to the pool wall.

A minute to understand grease traps, a practical invention under simple scientific principles, you didn't expect it, right?

The removal of oil in wastewater mainly includes floatable oil, fine dispersed oil, emulsified oil, and dissolved oil.

The grease trap is a treatment structure that uses the difference in the specific gravity of oil and water to separate and remove the suspended oil with large particles in the sewage.

Just listen to the name ... Oil separator.
