The dry dust collector produced by Dongguan Meijun Sandblasting Equipment efficiently solves industrial dust emission standards. The factory-level dust removal efficiency covers a large area and has a low failure rate. Dust collector introduction:
The dust collector is a device that separates dust from the flue gas, called a dust collector or a dust removal device. The performance of the dust collector is expressed by the amount of gas that can be processed, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. At the same time, the price, operation and maintenance costs, length of service life, and ease of operation and management of the dust collector are also important factors in considering its performance. Dust collector is a commonly used facility in boilers and industrial production.
在各个冒灰的地方设置吸尘罩，通过管道气路将含尘气体输送到除尘装置中，在其中进行气固分离后，将粉尘收集于该除尘装置内，而清洁的气体被引入总管或直接排入大气的整套设备，即是除尘系统，而除尘器是该系统中的重要组部分。 Uses: Set up dust extraction hoods in each place where dust is emitted, and convey dust-containing gas to the dust removal device through the pipeline gas path. After performing gas-solid separation in the dust collection dust, the dust is collected in the dust removal device, and the clean gas is introduced The main pipe or the whole set of equipment directly discharged into the atmosphere is the dust removal system, and the dust collector is an important part of the system. From the perspective of ventilation and dust removal, dust is all solid small particles that can exist in the air in a floating state for a long time. It is a dispersion system called aerosol, in which air is the dispersion medium and solid particles are the dispersed phase. A dust collector is a device that separates such small solid particles from an aerosol.
Classification: According to the principle of action, the dust collector can be divided into the following types:
1.Dry type mechanical dust collector mainly refers to the dust removal equipment designed by applying the inertia effect of gravity and gravity, such as high concentration dust collector such as sedimentation chamber, inert dust collector, cyclone dust collector, etc., mainly for high concentration coarse particle diameter dust For separation or concentration.
2. Wet type dust collectors rely on hydraulic affinity to separate and capture dust particles, such as spray towers, scrubbers, impact dust collectors, venturi tubes, etc., which handle high concentrations and large air volumes that occur during the production process. More dusty gas occasions are used. The separation efficiency of coarser, hydrophilic dust is higher than that of dry mechanical dust collector.
3. The particle layer dust collector uses the stacked layers of granular material with different particle sizes as filter materials to block the dust contained in the gas solution. It is mainly used for dust extraction in the production process of building materials and metallurgy. It is often used to filter dusty flue gas with high concentration, coarse particles and high temperature.
4. Bag type dust collector. The filter is a dust removal device with fiber woven fabric or filling layer as the filter medium. It has a wide range of uses, forms, dust removal air volume scale, and efficiency. It is mainly used for capture. Places with fine dust, both in exhaust dust removal systems and in air intake systems. In recent years, due to the continuous development of new filter materials, the development of fiber filtration technology has also accelerated, new products have continued to appear, and the application field has been increasingly widened.
5. Electrostatic precipitator This precipitator introduces dust-laden air into an electrostatic field. Under the action of a high-voltage electric field, the gas is ionized to generate electrons and positive ions. They move to positive and negative poles respectively. When the dust particles flow through the working electric field, The negative charges are removed at a certain speed to the settling plates opposite to the sign of their negative charges, and settle down there, so as to get rid of the airflow and be collected in the electrostatic precipitator. This dust collector has high dust removal efficiency, low resistance, and convenient maintenance and management. It has the same effect as the bag filter in capturing fine dust particles.
