What kind of fume purifier do I need for a kitchen with 4 stoves?

The kitchen with 4 stoves belongs to medium-sized catering units, and the most stringent national catering fume emission standards are that the purification rate of medium-sized catering units should reach more than 90%, the purification rate of particulate matter should reach more than 85%, and the purification rate of non-methane total hydrocarbons should reach more than 75%.

To achieve this effect, it is more reliable to use a high-standard fume purifier.

The subject can consider using Gojek's high-efficiency electrostatic oil fume purifier, if you use more chili peppers, you can add a UV light deodorizer, so that you can pass the environmental impact assessment.

The first look at the power of the fan, 4 stoves should be centrifugal or cabinet fan, such as light dishes can match 16,000 air volume, such as pepper can be matched with 20,000 air volume fume purifier!

If you have an ordinary stove, you can use a low-altitude fume purifier with 10,000 air volume, and it is recommended to buy a fume purifier with 12,000 air volume if you have a fierce stove, and you also need to consider the fan air volume, the ratio of the general fan air volume and the purifier is 1:2, and the fan is 2,000 air volume purifier is 4,000 air volume

The electrostatic oil fume purifier is paired with a UV photolysis purifier to remove oil fume and deodor.

It needs to be equipped with a fume purifier with 12,000 air volume, and the purification efficiency can reach more than 95%.

Environmental protection requirements are only commercial kitchens, that is, for him to provide food, but also mandatory installation of fume purifiers, and for the family, first, the family stir-fry produces not much, a family is mostly a few people, unlike commercial kitchens to provide food for many people, two to consider the cost and installation space, three, now many communities have public flues, a small amount of fumes are discharged to the roof through the public flue, so the impact is not large, so there is no requirement to install fume purifiers for family kitchens.

Now the family kitchen is installed with a range hood, the biggest difference between the range hood and the range hood purifier is that the range hood is only an exhaust function, the oil fume is discharged, and the oil fume purifier is mainly a purification function, and there is no fan (except for the composite type, most of the oil fume purifiers are not with a fan, and the fan should be selected according to the on-site situation), and a small number of family range hoods are advertised as having a purification function, which is just a simple treatment.

In general, commercial kitchens, that is, catering kitchens, must be installed with fume purifiers, in addition, kitchens used by units, factories and kitchens must also be installed, while family kitchens do not need to install fume purifiers.

Generally, small catering units are two stoves, and before opening for business, due to environmental protection requirements, a fume purifier must be installed, and when purchasing fume purification, it must first match the air volume. The air volume of the fume purifier is mainly divided into the following common air volume levels: 4000 air volume, 6000 air volume, 8000 air volume, 10000 air volume, 12000 air volume, etc., of course, there is a larger air volume level on the top, so how much air volume of the kitchen of the two stoves should be selected?

Under normal circumstances, a wok stove needs to be configured with an air volume of about 3000-4000m3 h, if it belongs to a cuisine with relatively large oil smoke, such as Hunan cuisine and Sichuan cuisine, etc., then add 2000 air volume on the basis of the previous one, which has a corresponding calculation formula: Restaurants or restaurants with small oil smoke: required air volume = number of stoves x 2000 + 2000.

Simplified to: required air volume = (number of stoves + 1) x 2000. According to the calculation results of the kitchen with two stoves, it is necessary to match the fume purifier with an air volume of about 6000.

Restaurants or restaurants with large oil smoke: 2000 air volume needs to be added on the basis The calculation formula is: required air volume = number of stoves x 2000 + 2000 + 2000.

The formula is simplified as: required air volume = (number of stoves + 2) x 2000. According to the calculation results of the kitchen with two stoves, it is necessary to match the oil fume purifier with an air volume of about 8000.

It is not difficult to match the air volume of the fume purifier, as long as you pay a little attention to the calculation, you can match the appropriate air volume with a high probability, which is a necessary and necessary important step before installing the kitchen fume purifier.

One: catering enterprises should choose the air volume model of the fume purifier according to their own cuisine and the number of stoves, each catering enterprise has its own cuisine, some dishes are relatively light, there is not much oil when cooking, and the fire is small, and the oil smoke produced is not much, and the taste is not large, and the fume purifier with low air volume can be matched according to the number of stoves. Some dishes are heavier in taste, with a lot of oil, a large fire, a stronger fume, and a larger flavor, so it is necessary to match the fume purifier with a larger air volume according to the number of stoves.

2. Don't be greedy for cheap and ignore the performance of the product.

At present, there are hundreds to tens of thousands of fume purifiers on the market, and most of the high-quality products need high-quality materials and technology to support, so that the products will be durable and durable, and the purification efficiency is high.

Three: try to choose a fume purifier with high purification efficiency.

In recent years, the national standards for oil fume emissions have become higher and higher. At the beginning, the state required the purification efficiency of the fume purifier to be more than 85%, and now some urban areas require the purification efficiency of the fume purifier to be greater than 90% to be considered up to the standard. Therefore, it is better for catering companies to choose oil fume purifiers with high purification efficiency as much as possible, which not only has a better experience, but also can easily cope with increasingly stringent standards.

1. Certification by relevant authorities (CEP certification, etc.).

2. Choose the fume purifier with how much air volume according to the stove eye in the kitchen.

3. Choose products with high cost performance, easy installation and maintenance, and high versatility to make the fume purification effect twice the result with half the effort.

1. The principle of choosing a fume purifier.

1) The technology is reliable, the purification rate is stable and meets the standard requirements. The nominal purification rate in the introduction of technical indicators is the purification rate at the initial stage of use, not a stable index, and the purification rate will drop sharply if it is not repaired in time or used for a long time. The purification rate of some purification technologies drops very quickly, such as if the filter material is not replaced in time in the filtration method, the smoke cannot be exhausted after blockage.

2) Low operating costs. It is necessary to calculate the cost of running water and electricity, especially the implied operating costs. In the technical information consulted, the pressure loss is not stated in the product. If the resistance is high, you need to increase the power consumption, which needs to be calculated to know.

3) Good fire performance. Oil fume purification has a good fire fighting effect, especially for stoves with open flames, it is more necessary.

4) Small footprint. Depending on the environmental conditions in the kitchen, choose equipment that takes up less space or can be mounted in the air.

5) Easy to install, easy to clean, easy to maintain.

2 Precautions for installation of oil fume purifier.

1) Choose a fume purifier that matches the exhaust air volume of the fan. The treatment air volume of the oil fume purifier is generally greater than the exhaust air volume of the fan. The method of estimating by stove head is not accurate, because the processing air volume of the oil fume purifier decreases with the use time, so it is necessary to leave a large margin.

For the duct system with high smoke exhaust resistance, choosing a fume purifier with suitable air volume can reduce power consumption.

2) Before the installation of the equipment, it is best to power on the test run for a period of time, check the operation effect, and check whether the machine will fail in transportation or handling, and then install it.

3) There are specific technical requirements for the fume purifier to receive the smoke exhaust system, and the pressure loss in the system should be taken into account to minimize the resistance.

4) The purifier should be synchronized with the fan as much as possible, and switch on and off at the same time.

5) The equipment box must be safely grounded and connected to the oil discharge pipe.

The more famous brand is Longxia Environmental Protection, the equipment is relatively stable, and the quality is relatively expensive.

Choose the right air volume according to the number of stoves in your restaurant.

Comply with local environmental protection fume purification standards and choose the appropriate purification rate.

Find a fume purifier manufacturer, which is cheaper and has guaranteed quality.

Don't buy the **low, no after-sales, no quality assurance.

1) The technology is reliable, the purification rate is stable and meets the standard requirements. The nominal purification rate in the introduction of technical indicators is the purification rate at the initial stage of use, not stable.

Calculation method of air volume of kitchen fume purifier;

1) According to the number of furnaces n, take the air volume of each furnace eye as 2000m3 h, and the required air volume of the purifier = n 2000 m3 h. When the coke hole is large and the working flue gas concentration is large, the air volume required for each coke hole needs to be increased to 3000-4000m3 h to achieve the purification effect.

2) When the smoke collector stove is very long and dispersed and there are many intermediate equipment, the total processing air volume q of the range hood can be determined according to the calculation method of the total projection area s of the smoke exhaust outlet (smoke hood) and the surface wind velocity v of the furnace. [**]

The specific formula is as follows:

q=sxv 3600m3 h v-take (calculated by length and width.)

3) Kitchen fume purifier corresponding to fan selection.

Pipeline resistance calculation: Pipeline resistance includes local resistance (resistance generated by reducers, elbows, and inlets) and resistance along the excavation spring (resistance generated by straight pipes in each section).

Calculate the total pressure of the fan = (pipe resistance + equipment resistance) 115%.

Pipeline resistance = resistance along the line + local resistance (see ventilation data for specific calculation methods).

Device resistance = 150-200pa

Calculate fan airflow = purifier airflow x (115-150)%.

This article introduces in detail the calculation method of the air volume of the small restaurant fume purifier and the kitchen fume purification spring resistor.
