The welding smoke centralized collection filter cartridge dust collector adopts advanced folded filter cartridges as filtering elements, which can remove small non fibrous dust. Compared with traditional pulse bag dust collectors, this machine has advantages such as small volume, large filtering area, high dust removal efficiency, low pressure loss, reliable operation, and long service life. Widely used for dust control and recovery in industries such as mechanical processing, welding dust casting, chemical engineering, ceramics, brake material processing, powder spraying, and purification of casting. After dust gas treatment, it meets emission standards and is a new form of pulse dust collector.
Dust containing gas enters the dust collector box from the air inlet located at the upper part of the dust collector, and from top to bottom. Due to the effect of gravity and downward airflow, the dust particles are first directly lowered into the ash hopper, and fine dust is captured on the outer surface by the filter cartridge. After the clean gas is filtered and purified by the filter cartridge, it enters the clean room from the center of the filter cartridge and is then discharged through the lower air outlet. As the filtering condition continues, the dust that accumulates on the surface of the filter cartridge increases. At this time, the pulse control instrument controls the solenoid valve to open according to the set pulse cycle and pulse interval, spraying high-pressure gas into the inner chamber of the filter cartridge, shaking off the dust on the surface, and falling into the ash hopper, which is discharged through the ash discharge port.
The internal filter element of the dust collector adopts a quick plug-in installation and disassembly method, which is more convenient. Workers only need to operate outside the dust collector. No need for personnel to drill into the dust collector, eliminating the difficulty of disassembly and maintenance.
2. Multiple fire star measures, directly designed inside the dust collector, can save external connection to the fire star device. Make its use safer and more reliable, eliminating customers' worries.
3. The internal filter element of the dust collector adopts all-round rotation for dust cleaning, making the dust cleaning more thorough and clean. It can always ensure that the dust collector has a certain ventilation capacity and improve the service life of the entire machine.
4. The dust collector control system adopts automatic control, making workers' operations more convenient and flexible.
The cleaning of the filter material of the welding smoke centralized collection filter cartridge dust collector is achieved through a pulse blowing mechanism controlled by a pressure difference sensor. After the purifier runs for a period of time, fine smoke and dust adsorb on the surface of the filter material, reducing its breathability. The two detection heads of the pressure difference sensor are installed on the raw gas side and one on the clean gas side. When the pressure difference detected by the pressure difference sensor exceeds a certain set value, a pressure difference signal is output. After receiving the signal, the pulse generator sequentially starts the pulse blowing valve, and clean compressed air is sprayed out from the valve port. The injected airflow blows the filter cartridge until the pressure difference is lower than another set value before stopping; The fine dust adsorbed on the surface of the filter material is removed by the airflow and falls into the dust collection hopper at the lower part of the chamber. Pulse injection requires clean compressed air of 0.5~0.6MPa and a continuous and constant air supply during operation. Compared with traditional electrostatic and mechanical filters, cartridge filters have the following advantages: low emission concentration, up to 5mg/m3, and generally other filters can only filter particles with a diameter of more than 0.5um; And our product can filter dust above 0.3um. Good breathability, lower air resistance than ordinary filters; Convenient ash cleaning, fully automatic ash cleaning, ensuring continuous and efficient production. Dust collection, convenient container loading and unloading, and sealed connection with the filter funnel to prevent dust leakage.
Characteristics of Filter Materials for Welding Smoke Centralized Collection Filter Cartridge Dust Remover
The welding smoke centralized collection filter cartridge dust collector uses an efficient filter cartridge as the filtering element. The filter cartridge uses a different filter material from traditional filters, with a layer of polytetrafluoroethylene film attached to its surface. Traditional filter materials (such as cotton cloth, cotton satin, paper, and other traditional cellulose) have a fiber gap of 5-60um. When smoke passes through, a portion of the dust particles in the smoke will enter the filter material and block the filter element; When the blockage situation gradually deteriorates and effective ash removal cannot be carried out, the air resistance of the filtering element will increase, and the air flow rate that can pass through will also decrease. If there is no automatic dust removal, the filtering effect will rapidly decrease, and the filter material used in this series of purifiers has a layer of polytetrafluoroethylene film attached to its surface, which has extremely small sieve holes that can block most of the submicron dust particles; Submicron dust particles gather on the surface of the filter material and form permeable dust blocking cakes. Most of the dust particles are blocked on the outer surface of the filter material and cannot enter the interior of the filter material. They can be timely and effectively removed under the blowing of compressed air. This filter material has a relatively high filtration efficiency, which is at least 3-5 times higher than traditional filter materials; And the service life is more than twice that of traditional filter materials
The dust removal process of welding fume dust collectors is mainly designed for the treatment of a large number of harmful dust particles generated during production in industries such as mechanical processing, foundry, powder recycling, medical production, food processing, welding fume, cutting, polishing, furniture production, etc. The processing air volume is 4000-6000m/h, and different combinations meet the processing requirements of different air volumes, It can meet the requirements of dust collection and treatment in multiple processes in the production workshop. The collection methods include mobile suction arms and fixed collection covers, which minimize the escape of dust into the workshop and ensure the working environment in the workshop. It can purify a large number of dust particles suspended in the air that are harmful to the human body.
The purification of smoke and dust generated by the welding smoke dust collector, as well as the recovery of rare metals and precious materials, can purify a large number of small metal particles suspended in the air that are harmful to the human body. It has a very high purification function, and its filter element adopts automatic rotation reverse blowing to clean the dust, making the surface of the filter core more thorough and clean, and always ensuring that the dust collector has a constant suction air volume;
