Brief introduction of DMC stainless steel pulse bag filter :
DMC type stainless steel pulse bag filter is made of high-quality 304 cold plate. It has a beautiful appearance, small footprint, high dust collection efficiency, large filtration area, stable operation and high reliability. Stainless steel dust collectors are widely used in the pharmaceutical, biological, chemical, food and other industries (such as tablet presses, sugar-coated pans, mixers, pulverizers, sifters and other process equipment) for dust removal, as well as electronics, machining, casting, Dedusting for building materials, ceramics, loading and unloading, mining, metallurgy and other industries. It also has good dust removal effect in a certain range for fine metal chips with a small specific gravity, foundry sand dust, cement, gypsum powder, charcoal powder, bakelite powder, and plastic powder. 19.5.

4. Strong applicability and good effect on solid media with large particles.
5. The product works stably and reliably, can be used continuously for a long time, and the design life is more than 10 years.
Stainless steel bag dust collector is mainly based on the performance of stainless steel plate to determine the special purpose of this dust collector:
First, some dust-containing gases are corrosive, and at this time, plates with anti-corrosive properties should be selected as dust collectors. Ordinary iron dust collectors do not have anti-corrosion properties, and only stainless steel dust collectors can be selected.
Second, the oxidation resistance of stainless steel dust collector can extend the life of the dust collector.
Stainless steel pulse bag dust collector using environment: Treatment of flue gas contains weakly corrosive gas or moisture, PH6 or PH8, flue gas contains weakly corrosive gas and moisture.
The stainless steel bag type dust collector mainly uses the corrosion resistance and oxidation resistance of stainless steel plates. The choice of stainless steel bag type dust collector is the same as that of ordinary iron bag type dust collectors. Manufacturers need to choose a suitable dust collector based on their own site, air volume, wind speed, etc.
[Working principle of stainless steel dust collector ]:
The dust collector uses a negative pressure working method. The dust-containing gas enters the box through the air inlet. Under the negative pressure in the dust bag , the gas penetrates the filter material from the outside of the bag and enters the bag. The dust in the gas is filtered on the surface of the filter bag. Clean gas enters the clean room and exits from the air outlet. When the dust accumulates on the surface of the filter bag, the resistance increases. When the set value is reached (it can also be set at a fixed time), the pulse valve opens, and the compressed air blows directly to the center of the filter bag. The filter bag is pulsed sequentially. Remove dust and resume low resistance operation.
1.Air inlet can be equipped with universal suction arm
2.Optional PLC to control wind speed
3.Can be equipped with explosion-proof motor and electrical box
Technical and organizational measures in equipment design, manufacturing, installation, commissioning, environmental acceptance, etc.
Our company is responsible for the special design of dust collectors-manufacturing-installation-commissioning, one-stop service for free training of technical staff, this all-inclusive turnkey project is a work policy that our company has always advocated, and we have a complete set of technical and organizational measures To ensure the successful completion of the project. Take the overall situation with technology and manage all aspects of penetration.
System installation and operation requirements
The on-site installation of the dust collector and control cabinet should be performed according to the product manual.
The installation quality must be thoroughly checked to ensure that its installation dimensions meet the drawings and quality requirements.
A thorough inspection of the quality of the welds must be performed to ensure that they do not leak.
All inspection doors and valves should be sealed and opened flexibly.
All foreign objects in the dust collector and the top cover of the upper box should be completely removed.
The filter bag installation and the keel installation must be very careful to ensure that the filter bag is not damaged, the keel is vertical, and no fire is allowed after installing the filter bag.
When the dust collector is used for the first time, the transmission machinery should be turned by hand first, and the motor can be started only when there is no failure. The dust collector should be powered on and commissioned to meet the requirements. Only after it runs normally, it can be officially put into operation.
After the control cabinet itself is installed and debugged on site, it must be linked with the main equipment, and the technical indicators of each project meet the requirements.
The user provides the control cabinet ground wire, and the ground resistance is <4Ω.
