Due to the installation or improper operation and maintenance of the dust collector, the dust removal device has air leakage, and a large amount of cold air is sucked into the bag filter, so that the local air temperature of the dust collector drops sharply and the moisture in the air is precipitated. , resulting in condensation. There are many reasons for the air leakage of the bag filter. In the process of making and installing the dust collector, there is leakage of air, which causes air leakage. If there is a leak in the unloader, the air is leaking. The non-standard pipe has leakage welding during the installation process. Air leakage, there is a leaky seal between the dust collector and the non-standard pipe flange connection, resulting in air leakage and so on.

The pulse bag dust collector cleaning control adopts PLC microcomputer program controller, which is divided into three control modes: constant pressure (automatic), timing (automatic) and manual. Constant pressure control: According to the set pressure difference, the pressure difference of the precipitator exceeds the set value, and the chambers are automatically cleaned one by one. Timing control: According to the set time, every other cleaning cycle, each room is cleaned up one by one. Manual control: On the field operation cabinet, you can manually control each room to clean it automatically, or you can clean each room separately. The control mode is selected by the user, and when the user does not request, the supply is controlled according to the timing.

The coarse dust particles fall directly into the bottom of the ash bucket, and the fine dust particles enter the middle and lower tanks with the airflow turning upwards. The dust accumulates on the outer surface of the filter bag, and the filtered gas enters the upper tank to the clean air collecting pipe-exhaust duct. , discharged to the atmosphere through the exhaust fan. The cleaning process is to first cut off the clean air outlet duct of the chamber, so that the bag of the chamber is in a state of no airflow (the compartment is shut off and cleaned). Then, the pulse valve is opened and the pulsed air is cleaned by the compressed air. The closing time of the shut-off valve is enough to ensure that the dust peeled off from the filter bag after the spray is settled to the ash bucket, and the dust is prevented from being separated from the air bag after being separated from the surface of the filter bag. The phenomenon of the adjacent filter bag surface completely cleans the filter bag, and the exhaust valve, pulse valve and ash discharge valve are fully automatic controlled by the programmable controller.

The pulse bag filter adopts the split-air pulse pulse blowing cleaning technology, which overcomes the shortcomings of the conventional pulse dust collector and the compartment back-blowing dust collector. It has strong cleaning ability, high dust removal efficiency, low emission concentration, low air leakage rate and low energy consumption. The steel consumption is small, the floor space is small, the operation is stable and reliable, and the economic benefit is good. It is suitable for the purification of dust-containing gas and the recovery of materials in metallurgy, building materials, cement, machinery, chemical, electric power and light industry. Due to the use of compartmental air-stop pulse to spray cleaning, the purpose of thorough cleaning can be achieved by spraying once, so the cleaning cycle is prolonged, the energy consumption of cleaning is reduced, and the consumption of compressed gas can be greatly reduced. At the same time, the fatigue of the filter bag and the pulse valve is correspondingly reduced, thereby multiplying the life of the filter bag and the valve piece.
