Dust Collector | Dust Collector | Technical Information

The number of vertical ribs of the dust removal framework is determined according to the force of the dust bag on the unit surface and the material of the filter bag. The earliest diameter of the dust removal bag was 120-130mm, and the number of vertical ribs of the dust removal skeleton was 8; At present, the size of dust-removing cloth bags is diversified, ranging from 120-180mm in diameter, and the vertical ribs of the dust-removing framework are correspondingly made into 12-24 pieces. Dust removal bags account for 20% of the operating costs of dust collectors. With the increase in the use of bag dust collectors, owners are paying more and more attention to the service life of dust removal bags. Therefore, many dust bag manufacturers are making their products longer and more attractive. It is expected to increase the number of vertical ribs in the bag cage to reduce the impact on the surface of the filter bag.

Have a practical transformation plan and reliable technical design
Exhaust gas emitted from various industrial furnaces in metallurgy, machinery, chemical industry, electric power and other industries not only has high temperature, but also contains a large amount of dust and harmful gases, which is one of the main factors causing environmental pollution. Under high temperature conditions, due to the large change in the viscosity of the exhaust gas, the humidity greatly decreases, and the phenomenon of fine particle agglomeration is greatly reduced, so it is difficult to separate the particles. Bag type dust collectors cannot withstand the high temperature of exhaust gas, and wet dust removal cannot make comprehensive use of its thermal energy; electrostatic dust removal has problems such as high one-time investment, large floor area and insulation. At present, most of the high-temperature dust-containing waste gas treatment methods in China are through water condensation, which reduces the high-temperature exhaust gas to about 200 ° C, and then uses a bag filter to remove dust.
The dust bag is the heart of the bag dust collector, and is generally called the dust bag or filter bag. The dust bag is the key part of the bag dust collector during its operation. Usually, the cylindrical filter bag is suspended vertically in the dust collector.
Dust bag prices, high temperature bags become a selling point. As an indispensable accessory in bag dust collectors-bag dust collectors are the core components of bag dust removal units, and are a type of dust removal products researched by manufacturers. The price is also highly concerned by users. At room temperature, medium temperature and high temperature bag Here, this year's high-temperature Metas (Aramid) bag has become the biggest selling point.
The filter material of glass fiber coated dust-removing cloth bag is a new type of filter material with high efficiency, low resistance, high filtering accuracy and long life. Other occupations have been widely adopted with excellent results. Glass fiber coated filter media is a high temperature resistant dust filter bag, which means that high temperature resistance is the minimum function of glass fiber coated filter media. However, when the temperature of the glass fiber coated filter media is above 80 ℃, The combined adhesive has been melted, and at this moment there will be a series of severe consequences such as film fall-off and increased resistance. Cloth,
In the dust removal system, the thermal insulation of the pipeline and the installation equipment is to cover the deployment of the dust removal equipment. The goal is to prevent the condensation of the flue gas in the system, the condensation of the material caused by condensation, and the agglomeration of the powder to affect the powder transportation. In terms of heat insulation and sound insulation, it can prevent the impact and nuisance of the dust removal system on external conditions. Therefore, the pipeline and installation equipment of the dust removal system must hold insulation. As for the degree of insulation, it depends on the temperature and identity of the flue gas, the production materials of the pipeline and installation equipment, and the external conditions restrict the conditions of the dust removal system. .
In order to prevent explosions, cloth bag dust collectors have adopted a variety of different methods to achieve a better safety purification, such as the design of explosion-proof structures, the addition of safety holes, etc., which is very important to achieve this safe operation. This method is also used to make the entire equipment use more in line with people's needs. Let us take a closer look at the detailed structure of the explosion-proof dust collector.
How to remove odor after dust removal2016 / 12/19 9:00:39
Recently, I often encounter customers saying that in addition to the requirements of dust removal and purification, their odor needs to be removed in the production process. For example, some severe odor conditions such as waste car decomposition and cutting industry, waste tire recycling industry, etc., because the odor is more serious, the staff of the operator cannot work normally. In response to this situation, Botou Nuohe Environmental Protection Equipment Co., Ltd. develops and produces A new product to remove odors: photo-oxygen catalysis equipment. This equipment not only has a good function of removing odors, but also does not cause secondary pollution of waste. Before the photo-oxidation catalytic equipment was developed,
The anticorrosion of the bag filter piping system is an important measure to ensure the normal operation and service life of the system, especially the pipeline system containing corrosive gases. The main method of anti-corrosion of bag filter is to use anti-corrosive coating and anti-corrosive material.
After the explosion of the bag filter, a secondary explosion often occurs. This is because during the first explosion, a lot of dust was deposited together.
The maintenance and maintenance of the boiler dust collector is very important. It is directly related to the normal operation of the boiler dust collector. When repairing and maintaining, you must pay attention to the thermal insulation of the boiler dust collector. Then why should the boiler dust collector be insulated? What's the purpose?

Whether the design of the dust collection point and wind speed of the dust collector is reasonable, on the one hand, it determines the initial investment of the user, and on the other hand, determines the dust control effect. , Make careful calculations, and choose based on actual work experience.
The selection of filtering wind speed of the dust collector in the crushing workshop of the ore dressing plant is unreasonable, the selection of the filtering wind speed is too fast, and the cost of the equipment is high; the selection of the filtering wind speed is also likely to cause damage to the bag of the dust collector. If the damaged dust collector bag is not replaced in time, the induced draft fan of the dust collector equipment will also be damaged.
When a person's heart is not clean, people will easily get sick. By the same principle, when the "heart" of the dust bag is not cleaned in time, the dust bag will not work properly. what is it then? The dust removal skeleton is the "heart" element of the dust removal bag. If there is too much dust in the dust removal framework, it will also affect the service life of the dust removal bag. The cleaning of the dust of the dust removal framework mainly depends on the following points
