Main application of the Micro Portable Pulse Dust Collector:

The Micro Portable Pulse Dust Collector has two models, single air duct and double air duct. It is the latest pulse dust removal equipment launched by Huazhong Machinery.

Suitable for the following occasions: dust removal and purification of flue gas in grain storage and transportation units, grain processing and cleaning enterprises, and iron and steel plants; dust removal of calcium carbide furnaces and various electric furnaces in ferroalloy plants; dust removal of coal-fired boilers and small boilers; high-temperature flue gas dust removal of smelters; aluminum Factory flue gas purification; garbage incinerator dust removal; cement plant rotary kiln tail and kiln head dust removal.

Performance characteristics of Micro Portable Pulse Dust Collector:

The Micro Portable Pulse Dust Collector uses filter bags to filter and use pulse blowers to remove dust. The dust collector has powerful dust removal ability, can remove dust efficiently, has low emission concentration value, low air leakage rate, low energy consumption, and low space occupation.

The equipment can operate reliably and stably. With the accumulation of filtration time, the dust layer on the filter bag of the dust collector continues to thicken, and the resistance of the dust removal equipment continues to increase. When the resistance of the Micro Portable Pulse Dust Collector rises to the set fixed value, the dust cleaning device starts to clean the dust. First, the electromagnetic pulse valve is opened, the compressed air is rapidly expanded in the equipment in a short time, and then the air is poured into the filter bag, causing the filter bag to expand and deform and generate vibration.

With the continuous effect of the reverse airflow, the dust attached to the outer surface of the filter bag of the Micro Portable Pulse Dust Collector is blown away into the soot bucket by the airflow. After the ash removal is complete, close the electromagnetic pulse valve. Open several groups of pulse valves according to the set time sequence,from the beginning of the first group of cleaning to the beginning of the next cleaning cycle is a cleaning cycle.

After filtering and dust removal, the trapped dust falls into the ash hopper and is removed by the ash discharge valve at the outlet of the ash hopper.

The dust-containing gas enters the dust box through the air inlet of the  Micro Portable Pulse Dust Collector for sale, and the fine dust particles are blocked on the outer wall of the filter bag due to the various barrier effects of the filter bag.

The purified gas is discharged through the air outlet of the box on the filter bag. As the use time increases, the dust adsorbed on the surface of the filter bag of the  Micro Portable Pulse Dust Collector continues to increase, the air permeability of the filter bag gradually weakens, and the resistance of the dust collector continues to increase.

In order to ensure that the resistance of the vacuum cleaner is controlled within a limited range, the pulse controller sends a signal to open the electromagnetic pulse valve in sequence, and the compressed air in the air bag is sprayed from each nozzle of the blowing pipe to the filter bag (called primary air) At this time, the airflow in the filter bag expands sharply, and the impact of the reverse pulse airflow disappears immediately.The filter cartridge shrinks sharply, the dust accumulated on the outer wall of the filter bag is removed, and the fallen dust enters the ash hopper.

Since several groups of filter bags are cleaned in sequence, and the dust-laden air is processed continuously, the processing capacity of the  Micro Portable Pulse Dust Collector does not change during the clean.

The pulse controller is the main control device of the Micro Portable Pulse Dust Collector for sale. The electromagnetic pulse valve is controlled by its output signal. The compressed air blown by the electromagnetic pulse valve cleans the filter bag in sequence.

The resistance of the dust collector can be kept within the set range,to ensure the dust removal capacity and dust removal efficiency of the dust collector.

1. When installing the Micro Portable Pulse Dust Collector, check whether the motor of the dust collector and the air compressor motor rotate normally, and whether the air inlet hose of the dust collector is installed in place.

2. Before starting the small pulse bag filter, check the installation and sealing of the filter cartridge and bag.

Check for leaks in equipment pipe joints.

Adjust the backflush pressure, pulse frequency, and pulse width. (This equipment is equipped with a pressure switch, and the pulse dust collector will not work when the set pressure difference is not reached)

3. When starting the Micro Portable Pulse Dust Collector, first start the air compressor switch and then the dust collector switch. Turn off the dust collector ten minutes after the end of the operation, and turn off the compressor twenty minutes later. If the operation is only stopped for a short time, only the fan will be turned off and the compressor will not stop to ensure that the filter cartridge and cloth bag are clean. Continue to work and turn on the fan.

4. After the Micro Portable Pulse Dust Collector is started, pay attention to whether the dust collector and the air compressor are working properly. Do not open the observation hole and perform ash removal operations without completely closing the dust collector.

5. After the Micro Portable Pulse Dust Collector is stopped, if it is not for a long time, the air compressor can not be turned off. The oil-water separator should be discharged once every shift. Depending on the ash in the ash bucket, clean the ash at least once per shift. At the same time, each shift needs to check whether the gas emission of the dust collector chimney is good. If dust is found in the chimney, the damaged filter cloth and cloth bag should be replaced in time.

6. After using the small pulse bag filter for a long time, the user and maintainer should check the sealing strip on the door, and replace it in time if it is aging. At the same time, equipment users and maintainers need to check the compressed air system and dust removal system of the dust collector regularly. If any abnormalities are found, they should be dealt with in time. If the pulse valve or diaphragm is found to be faulty or damaged, it should be repaired or replaced in time.

Installation process of Micro Portable Pulse Dust Collector

Micro Portable Pulse Dust Collector usually works under negative pressure. If the equipment is not well sealed and leaks, it will inhale a large amount of outside air or rain, which will cause the filter bag to become damp and compact, and increase the operating resistance of the equipment. . Therefore, the tightness of the pulse dust collector is required to be strictly guaranteed, and the air leakage rate should be less than 3%. In the process of equipment installation, welding quality is very important. All welding must be implemented in accordance with the specifications and standards of the corresponding country and industry. After the welding is completed, kerosene, fluorescent powder, etc. shall be used for leakage inspection, and the leakage must be re-welded. The inspection door of the dust collector must be sealed with a rubber strip and checked and replaced frequently. At the same time, check the flange and each discharger carefully, and do a good sealing operation to reduce the air leakage of the dust collector. This can effectively protect the filter bag and avoid the occurrence of paste bags.Ensure that the equipment runs smoothly with low resistance.

1. When hoisting a Micro Portable Pulse Dust Collector, care should be taken to avoid damage to the dust collector box and accessories due to bumps. The aperture of the topping must be smaller than the dust collector. And welded on the top of the ash storage.

2. Turn on the air compressor and connect it to the air tank of the Micro Portable Pulse Dust Collector.

3. Before installation, check all parts of the dust collector to see if the parts are intact and complete. If missing, damaged or deformed parts are found, they must be repaired or replenished before installation.

4. The connection of the air bag and the injection pipe of the electromagnetic pulse valve should be reliably sealed, and there should be no air leakage.
