Long bag low pressure pulse dust collector
Long bag low pressure pulse dust remover @ 长 袋 Low voltage pulse dust remover manufacturers @ 长 袋 Low pressure pulse dust remover manufacturers offer
Long-bag low-pressure pulse dust collector is a kind of 21-century-level long-bag off-line pulse dust collector, which is introduced to users by our company's research technology experience and achievements for more than ten years. Technology products. It uses offline low-pressure pulse spray dust cleaning technology to prevent dust re-attachment and runaway problems, enhance the cleaning effect of the filter bag, increase the filtration speed, save energy for cleaning and extend the life of the filter bag. The long-bag low-pressure pulse bag type dust collector uses a PLC programmable controller to automatically control the entire process of ash cleaning and ash transportation. It is a large-scale dust removal equipment with large air volume, good dust removal effect, dust removal efficiency ≥99.8%, emission concentration in compliance with emission standards ≤50mg / Nm3, reliable operation, convenient maintenance, and small footprint. It is widely used in the metallurgy industry for the preparation of coal injection raw materials for steelmaking blast furnaces, building materials industry, electric power, chemical industry, carbon black, asphalt concrete mixing, boilers, flue gas dust removal and other industries for dust management and material recovery.
Construction and working principle:
主要由上箱体、中箱体、支架、滤袋及喷吹装置、卸灰装置、输灰装置等组成。 The long-bag low-pressure pulse dust collector is mainly composed of an upper case, a middle case, a support, a filter bag and a blowing device, an ash discharge device, and an ash conveying device. Dust-containing air enters the ash hopper of each room from the air inlet channel of the dust collector and is guided by the hopper guide device. Large particles of dust are separated and fall directly into the ash hopper, while the finer dust enters the middle cabinet uniformly. While adsorbed on the outer surface of the filter bag, clean gas penetrates the filter bag and enters the upper case, and is discharged into the atmosphere through various off-line valves and exhaust pipes. With the progress of the filtering conditions, the dust on the filter bag accumulates more and more. When the equipment resistance reaches a limited resistance value (generally set to 1500Pa), the dust cleaning control device sets the differential pressure or the dust cleaning time. After the set value automatically closes the off-line valve of the first room, the electronically controlled pulse valve is opened in accordance with the set procedure to stop the air blowing. The compressed air is used to make the instantaneous spray increase the pressure in the bag and shake the dust on the filter bag ( Even fine dust can be cleaned into the hopper. The dust is discharged from the ash discharge mechanism, and the clean air is discharged into the atmosphere through the clean air channel.
Main structure and characteristics of long bag low pressure pulse dust collector :
1. With advanced automatic off-line valve and off-line three-state ash cleaning mechanism, advanced technology, reliable work and low ash cleaning energy consumption.
2. Reasonable design of the air inlet channel and ash bucket diversion technology have solved the phenomenon of uneven airflow in each sub-chamber often produced by general bag filter.
3. A special large-capacity pulse valve gas storage bag is designed to meet the requirements of low-pressure pulse gas injection.
4. The upper end of the filter bag adopts a spring ring type, which not only has good sealing performance, but also is quick and easy to repair and change the bag, so that the bag can be changed outside the machine. When changing the bag, the filter bag skeleton is drawn from the clean room of the dust collector, the dirty bag is put into the ash hopper and taken out through the hopper hole, which improves the bag changing environment.
5. The structure design of the upper end of the bag cage can be selected according to different working conditions. There are a variety of structural types (octagonal, round, etc.). There are strict requirements for the manufacture of bag cages. The company's bag cages are imported from abroad. The technical production of automated production line processing, its indicators are about 50% higher than industry standards.
6. The standard length of the bag cage is 6 meters. If the user's space is limited, it can be increased by 1-2 meters as needed. When the same air volume is handled, the equipment has a smaller footprint than other anti-dust dust collectors and conventional pulse dust collectors. Save 30-50%, and the equipment weight can be reduced by about 40%.
7. The service life of the diaphragm of the electromagnetic pulse valve wearing parts is more than 1 million times. Adopting low-pressure pulse injection technology and using straight-through low-pressure pulse valve, the injection pressure is only 0.2 ~ 0.4MPa. Due to the low injection pressure, the pressure of the diaphragm of the pulse valve and the impact force during opening and closing are low, and the opening and closing is fast. Strong cleaning ability. At the same time, due to the long dust cleaning cycle, the number of pulse valve openings is correspondingly reduced, thereby extending the service life of the pulse valve and improving the reliability of the pulse valve.
8. The dust collector can be controlled by an advanced program controller, which has three methods: differential pressure, timing, and manual. It can achieve comprehensive system control of the dust collector pulse valve and ash discharge valve. If required, it can also control the sensor element on the body. Devices such as temperature perform auxiliary alarm control.
设备技术性能、工艺参数： Technical performance and process parameters of long bag low pressure pulse dust collector :
Filter bag material:
Under normal working conditions, 450-500mg / m2 polyester needle felt filter material is used when the temperature is ≤120 ℃.
If used in flammable and explosive occasions, please specify the use of anti-static polyester needle felt felt filter material.
When using at high temperature 130 ℃ ～ 250 ℃, please indicate the use of high temperature resistant filter material such as Normex needle felt or glass fiber filter material, which is selected according to the working conditions.
There are various control methods
1) Ash cleaning controller The dust cleaning controller opens the off-line valve and the electromagnetic pulse valve according to the set procedure.
2) The control cabinet is equipped with a programmable controller to the dust collector
The solenoid valve pulse valve, ash unloading mechanism, relevant dust collector body and sensor parts implement full-pressure differential or timing, manual ash removal control in three ways, and monitor pressure, temperature and other parameters.
