TBLMA series pulse dust collector is a dry dust collector, it is suitable for capturing fine, dry non-fibrous dust.
TBLMA series pulse dust collector is a high-efficiency dust collector product produced by our company. 99% of the dust is collected. Under the new national environmental protection standard conditions, the TBLMA series pulse dust collector is widely used in feed, cement, food, pharmaceutical, machinery, chemical, metallurgy, steel, and other industries.
Working principle of TBLMA series pulse dust collector:
The dust gas gets into the ash hopper from the air inlet and enters the filter bag room, and the big particles of dust directly fall into the ash hopper under the action of gravity. The clean gas is filtered through the filter bag enters the clean air chamber, and then passes through the air outlet of the clean air chamber and is discharged by the fan. The dust accumulates on the outer surface of the filter bag and keeps increasing so that the resistance of the bag filter continues to rise. In order to keep the resistance of the equipment not exceeding 1500Pa, the bag filter can continue to work, and the dust on the filter bag needs to be removed regularly. Soot cleaning is to start the electromagnetic pulse valve in a timed sequence by the pulse controller, so that the compressed air (0.5～0.7MPa) in the bag is ejected from the holes of the injection pipe and enters the filter bag, so that the filter bag expands rapidly in an instant, accompanied by the reverse airflow. Shake off the dust to the action to achieve the purpose of cleaning.
Structure of TBLMA series pulse dust collector:
(1) Box body of TBLMA series pulse dust collector: including bag room, clean air room, flower plate, filter bag, filter bag skeleton, gas storage bag, control cabinet, and box body. The designed pressure resistance is below 1500Pa.
(2) Air outlet system of TBLMA series pulse dust collector: including fans and motors equipped with fans.
(3) Blowing system of TBLMA series pulse dust collector: including main gas pipe, blowing pipe, pulse valve, and controller.
(4) Ash discharge system of TBLMA series pulse dust collector: the lower box adopts the ash bucket type.
TBLMA series pulse dust collector can install a blowing pipe according to the outlet of each pulse valve, aiming at the filter bag installed under the blowing hole, so as to improve the high-efficiency pulse dust cleaning work.
How to choose TBLMA series pulse dust collector:
TBLMA series pulse dust collector is a small pulse dust collector, its specifications are 24 bags, 36 bags, 48 bags, 64 bags, 72 bags, 80 bags, 96 bags, 100 bags, 120 bags, etc., pulse cloth bags The working process of the dust collector: the dust-laden gas gets into the ash hopper under the action of the induced draft fan, and is divided into each filter bag after passing by the deflector evenly. The dust is intercepted on the outer surface of the filter bag, and the gas passes through the filter bag and is discharged after passing through the clean air chamber. The dust captured by the bag filter on the outer surface of the filter bag will lead to the reduction of the air permeability of the filter bag, and the resistance of the filter will continue to increase. Wait until the resistance reaches the set value (differential pressure control) or the filtering time reaches the set value. value (time control), the pulse valve that is usually in the closed state is opened for a very short period of time (about 0.1s) under the pulse injection control of the pulse injection controller PLC, and the high-pressure gas enters the injection pipe from the airbag instantaneously, and the high-speed ejected from the blowhole. The high-speed airflow injected into the filter bag will also generate secondary drainage several times that of the injected gas. The combined action of the jet airflow and the secondary drainage makes the pressure inside the filter bag rise rapidly, the filter bag changes from the original concave shape to the convex shape and generates a large reverse acceleration when the deformation reaches the maximum value. , The dust adsorbed on the filter bag is mainly under the action of this reverse acceleration, and is separated from the surface of the filter bag and falls into the ash hopper, and the resistance of the dust collector decreases accordingly. The process of removing dust from the filter bag surface is called cleaning. The cleaning work is carried out row by row. Each time the pulse valve is actuated, a row of filter bags is cleaned. The pulse valve acts in sequence according to the set time interval and sequence until a cycle is completed.
