1. Overview of high-efficiency and fast fiber ball filters.

The high-efficiency and fast fiber ball filter is a steel round tank, which adopts two forms: fiber ball filter media, different gas separation backflushing and mechanical backwashing according to the backwashing mode, which has a compact and integrated structure, which is easy to install and operate. The filter material is wear-resistant and corrosion-resistant, has high porosity, large sewage interception capacity, moderate specific gravity, and is easy to backwash.

2. Description of the characteristics of high-efficiency and fast fiber ball filter.

1. The diameter of the modified fiber ball wire is fine, the specific surface area is large, and the specific surface area is as high as 2000 g. Due to the characteristics of fine fiber diameter, the pores of the filter layer after superposition are small, and the porosity of the filter layer after superposition is more than 80%, and the interception effect on suspended solids is better than that of other filter media. Therefore, injection water treatment for low permeability reservoirs is particularly ideal.

Filtration that requires the discharge and reuse of highly suspended solids water is more applicable.

2. The filament is modified to make it hydrophilic and oleophobic. Regardless of whether the modified filament is adhered to pure oil or oily sewage, water molecules can penetrate into the surface of the modified filament when it encounters water, forming a layer of water film to separate the filament from the oil. When backwashing, the ** adhered to its surface can be cleaned, and the backwash regeneration performance is particularly good.

3. The modified fiber ball is larger than the ordinary fiber ball and does not stick to oil, and can sink to the bottom of the tank under the action of hydraulic power during filtration, and the pore structure of the filter layer is good. When the modified fiber ball filter media is running, the porosity of the filter layer gradually decreases along the direction of water flow. A relatively ideal pore distribution state of large and small on the filter material has been formed, and the interception effect is enhanced and the filtration effect is good.

When cleaning, due to the absence of inlet water pressure, the floating orifice plate is restored to its original position, so that the fiber is in a loose state, and then water and compressed air are combined to wash out, and the intercepted and adsorbed impurities are cleaned out, and the cleaning is thorough.

3. Scope of application of high-efficiency and fast fiber ball filter.

The high-efficiency and fast fiber ball filter removes suspended solids from the original water quality. It is widely used in water supply treatment with high water quality requirements in life and various industries, and can also be used as advanced treatment for various sewage reuse.

1. It is widely used in circulating water side stream filtration, domestic water advanced treatment, boiler feed water treatment, reverse osmosis pre-filtration, and sewage reuse filtration.

2. The fiber ball filter is suitable for coarse, medium and fine filtration of oilfield oily sewage reinjection and the effluent treatment of oilfield and refinery wastewater.

The high-efficiency filter is mainly used to capture particles and dust below 3um and various suspended solids. Ultra-fine glass fiber paper is used as filter material, and the glue is specialized.

Plate paper, aluminum.

Membrane and other materials used as dividing plates have the characteristics of high filtration efficiency, low resistance and large dust holding capacity. HEPA filters can be widely used in the air supply at the end of the air conditioner in the dust-free purification workshop of optical electronics, LCD liquid crystal manufacturing, biomedicine, precision instruments, beverage and food, PCB printing and other industries. Both HEPA and UHPA filters are used at the end of the cleanroom and can be divided into the following types of filters in their structural form:

There are partition high efficiency, no partition high efficiency, large air volume high efficiency, ultra-high efficiency filter, etc., if you are interested, you can contact Shanghai Zeding Electromechanical Equipment.

Precautions for manufacturing high-efficiency filters in Liaojing.

Installation requirements for HEPA filters:

Installing a HEPA filter is net internalized air conditioning.

The key to the construction and installation of the capacity system and clean room should pay attention to the following points:

Clean before installation;

The system should be air-blown and cleaned;

The purification workshop should be fully cleaned again, such as vacuuming with a vacuum cleaner, not using an ordinary vacuum cleaner, and must use a vacuum cleaner equipped with an ultra-clean filter bag;

If installed in the ceiling, the ceiling should be cleaned;

Then the system is tested for 12 hours and the clean workshop is cleaned again before the high-efficiency filter can be installed.

The tank body has carbon steel, stainless steel, etc., and the materials inside include fiber balls, fiber bundle filter materials, etc.

The function of the filter is to remove suspended solids and particulate matter from the water body, reduce turbidity, purify water quality, reduce the generation of dirt, bacteria and algae, rust and so on in the system, so as to purify water quality and protect the normal operation of other equipment in the system.

Filter Introduction:

The filter is an indispensable device on the old conveying medium pipeline in the state, which is usually installed in the inlet end of the pressure reducing valve, pressure relief valve, water level valve, and other equipment of the square filter. The filter is composed of a cylinder, a stainless steel filter screen, a sewage discharge part, a transmission device and an electrical control part. After the water to be treated passes through the filter cartridge of the filter screen, its impurities are blocked, and when it needs to be cleaned, as long as the detachable filter cartridge is taken out and reloaded after treatment, it is extremely convenient to use and maintain.

The key point of whether the filter is good or not is whether the accuracy of the filter is high enough and whether it can meet the requirements of industrial filtration. The filter is easy to use when it can produce a continuous and stable output that meets the industrial requirements for a long time.

How to make the filter easy to use is to improve the filtration accuracy of the filter and prolong the service life of the filter.

The filtration accuracy of the filter.

The filtration accuracy of the filters ranges from microns to 600 microns. The diameter of the source port of the bag is made of stainless steel and galvanized steel ring argon arc welding technology. The diameter error is only less than, the horizontal error is less, and the filter bag made of this steel ring can be installed in the equipment to improve the degree of sealing and reduce the probability of side leakage.

Non-woven filter bags are used in many aspects of industrial water, such as boiler water, production line water, product water, sewage treatment and other links, and these different links have different requirements for the accuracy of the filter bag. Nonwovens have a wide range of filtration and can meet the filtration requirements of these links. Shuitianlan can produce non-woven filter bags with corresponding precision according to customer requirements to meet the different filtration needs of customers.

How to extend the life of the filter.

Under normal circumstances, when the pressure difference of the filter reaches 2-3 kg, it means that the filter bag is basically blocked, and at this time, there is little liquid flowing out of the outlet of the filter, and the filter bag needs to be replaced. In addition, according to the specific use of the filter, if the production worker has the requirement to keep the flow rate of the filter not lower than the general flow rate, the filter bag should be considered when the pressure difference reaches about 1 kg. The service life of the filter bag is mainly determined by the turbidity of the raw water, the filtration time, the filtration flow, and the filtration area of the filter bag.

After a period of use, the filter should also be cleaned to remove the impurities and stains accumulated on the filter bag during the operation of the system, and the cleaning frequency needs to be determined in combination with the actual production and use conditions.

Whether the filter is good or not depends on which filter is chosen;

First of all, it depends on what your filter media is, then what are the requirements, and what kind of effect you want to achieve, to choose the right filter.

Filters are available in coarse and fine filtration.

There are many kinds of filters, filtering solids, filtering liquids, filtering gases, and different types of filters have different functions.

Next, let's talk about the role of industrial filters that filter liquids.

The industrial filter is mainly used to filter the impurities in the electrolytic copper foil stabilization tank, and the impurity composition of the sewage here is relatively single, which is more suitable for the use of large-flow single-bag filters. The industrial filter has a high filtration accuracy, up to the highest level, which can meet the needs of chip electrolyte filtration.

According to the needs of actual production, the flange quick-opening stainless steel bag filter has reasonable overall structure, good sealing, strong circulation ability and easy operation, which can meet the filtration needs of various industrial water. The leakage probability of the filter bag is small, the filtration accuracy is high, and the inner and outer surfaces of the filter are solved by mechanical sandblasting and polishing, which is average and easy to clean. We know that the flange quick-opening stainless steel bag filter adopts the side-in and side-out mode, which has a large inlet and outflow water, high water yield and stable water quality.

It is mainly used in reverse osmosis, ultrafiltration and other membrane filtration equipment to filter the water that needs to enter the reverse osmosis membrane and ultrafiltration membrane to ensure that there will be no excessive substances blocking the reverse osmosis membrane and ultrafiltration membrane, and to protect the safety of reverse osmosis membrane and ultrafiltration membrane.

Nanofiltration (NF), ultrafiltration (UF), reverse osmosis (RO), electrodialysis (EDI) and other system security filtration and terminal filtration;

Filtration of pharmaceutical injections, large infusions, eye drops, Chinese herbal medicines, etc., extraction, purification and concentration of biological preparations;

pre-filtration and terminal filtration of high-purity water for electronics, microelectronics and semiconductor industries;

Oilfield reinjection water, boiler feed water, chemical reagents, liquid organic products, high-purity chemicals, pesticides, etc. filtration;

Filtration of drinking purified water, mineral water, fruit juice, tea drinks, and health drinks;

Today's car needs to be briefly introduced to friends. Many friends have asked the car Qingnai, what is the filtering function of the filter. Let's take a look at it with a car.

Introduction to Filter Filtering: Introduction.

The filter is an indispensable device in the media pipeline, which is usually installed at the inlet of equipment such as pressure reducing valves, pressure relief valves, and water level valves, such as square filters. It is composed of a filter cartridge, a stainless steel strainer, a blowdown part, a transmission device and an electric adjustment part. After the water to be treated passes through the cartridge of the filter screen, its impurities are blocked.

When cleaning, you only need to take out the detachable filter cartridge and reload it after treatment, which is extremely convenient to use and maintain.

What is the function of the filter &mdash&mdash air adjustment filter element type.

At present, there are two types of air filters on the market: ordinary air filter and activated carbon series air filter.

1.Ordinary empty adjustable filter.

It is made of specific environmentally friendly filter materials that are produced and folded, and are mostly white single layers. It only inhibits the ingress of dust and particles.

2.Live Wheel Carbon Series Empty Adjustable Filter.

This kind of activated carbon filter cloth is made of non-woven fabric (non-woven fabric) sandwiched with micro-particle activated carbon on both sides, and then processed into an air-adjustable filter after deep processing. When the k0 ] gas is blocked, it can adsorb the air in a short time, empty other tiny things and more harmful substances, and the filtration effect needs to be much better than that of ordinary filters.

What is the function of the filter &mdash&mdash update cycle.

I think the critical time to replace the air filter depends on the external environment and how often the CAR air filter is used. Under normal circumstances, it can be replaced every time it is repaired, ranging from 7500 km to 1000 km. Most of the driving is basically circulating air in the car, so as long as you don't need to go outside the car, there won't be too much debris inside.

Also, it doesn't have to be expensive. It doesn't hurt to change it often. If the air filter element is replaced according to the frequency of use, under normal circumstances, the car 4S needs to be replaced once a year.

If the service frequency is high, it will be quite good to replace the air air in the car twice a year, and the filtration performance will be better, so the air air in the car will be better. In most cases in China, the maintenance cycle of the car air filter is 10,000 kilometers or half a year, and the car is used in the case of serious haze, and it is best to replace it every three months.

There's a lot to know about filter adjustments! And not only that, of course, but also the mysteries that you explore in front of the screen. Another point is that although the activated carbon filter element has a better effect than the ordinary filter element, it is easy to clog and the replacement cycle is short, so you can make a good choice according to your own needs.

The above is the information shared by the car about the filter function. I hope that friends can help after reading the introduction of the car.

Millions of car purchase subsidies.
