Description

Bag-type dust collector

Technical Field

The utility model relates to a dust purification technical field, more specifically relates to a sack cleaner.

Background

The existing bag-type dust remover has detailed parameters, and the pulse bag-type dust remover is mainly divided into an air box pulse dust remover, a pulse valve line-spraying dust remover and a pulse single-machine bag-type dust remover. Generally, the bag-type dust collector is a type of bag-type dust collector which removes dust attached to a filter unit (a dust collecting bag or a filter cartridge) by blowing compact air. According to the type and the fineness of the bag-type dust remover, a plurality of or a plurality of groups of pulse valves can be arranged, the pulse controller or the PLC is used for controlling, one group of pulse valves is opened each time to remove the dust of the part of the bag or the filter cylinder controlled by the pulse controller or the PLC, while other bags or filter cylinders are in normal responsibility, the next group of pulse valves are opened after a period of time, and the cleaning process is that the air duct of the clean air outlet of the chamber is firstly cut off, so that the bag of the chamber is in a shape without air flow (air blowing and dust removal in the chamber). Then the pulse valve is opened, the dust is intermittently and pulse-blown to remove ash by using the compressed air, the closing time of the stop valve is enough to ensure that the dust stripped from the filter bag after being blown is settled to the dust hopper, the phenomenon that the dust is attached to the outer surface of the adjacent filter bag along with the airflow after being separated from the outer surface of the filter bag is avoided, the dust removal of the filter bag is complete, and the exhaust valve, the pulse valve, the ash discharge valve and the like are intermittently and fully automatically controlled by the programmable controller. The dust-containing gas enters from the air inlet, and when the dust passes through the dust hopper, part of large-particle dust in the gas is separated out under the effects of inertia force and gravity and directly falls into the bottom of the dust hopper. The dust-containing gas enters the filter bag filtering area of the middle box body after passing through the dust hopper, the gas passes through the filter bag, the dust is blocked on the outer surface of the filter bag, and the purified gas enters the upper box body through the filter bag opening and then is discharged from the air outlet. The bag type dust collector has the defect that the bag type dust collector has half the dust collection effect on wet and viscous dust, and is not as good as a wet type dust collector.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a can improve dust collection efficiency's sack cleaner.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a bag-type dust collector, includes the dust removal box, be provided with a plurality of filter bags in the dust removal box, the bottom of dust removal box is provided with the ash bucket, the ash bucket bottom is provided with unloads grey valve, one side of dust removal box is provided with steam heating equipment, steam heating equipment is equipped with steam inlet and play steam pipe, go out the steam pipe be equipped with a plurality of with the steam jet of filter bag one-to-one.

The dust particles are mutually impacted to generate static electricity, so that the outer surface of the filter bag is provided with the static electricity which is the same as that of the dust particles, the filter bag is subjected to reverse blowing at a constant temperature of 50 ℃ through steam heating equipment, the inner part of the filter bag is provided with charges opposite to the outer part, and the dust is adsorbed on the filter bag and is blocked outside. On the other hand, because the air contains moisture, the efficiency of the bag-type dust remover can be better improved by using the dry gas back blowing. The utility model discloses a steam heating equipment carries out invariable 50 ℃ temperature blowback gas to the filter bag, strengthens the inside and outside electrostatic action of filter bag, improves the efficiency of dust absorption on the filter bag, can reduce the dust concentration of dusty flue gas by a relatively large margin, improves the ability that the amount of wind was handled to the dust remover, improves dust collection efficiency.

Furthermore, a control valve for controlling the opening and closing of each steam jet port is arranged on the steam outlet pipe, and the steam is controlled to be jetted according to the requirement by controlling the opening and closing of the control valve, so that the waste of the steam is avoided.

Furthermore, a pressure gauge and a thermometer are arranged on the steam heating equipment, so that the pressure and the temperature of the steam heating equipment can be visually displayed, and the steam heating equipment is convenient to monitor and adjust at any time.

Furthermore, one side of the dust hopper is provided with a dust poking hole, when the dust in the dust hopper is accumulated too much, the dust is poked down through the dust poking hole, and the inner part of the dust hopper is prevented from being blocked.

Furthermore, the bottom of the ash bucket is located a baffle is arranged above the ash discharge valve, and a # -shaped baffle is arranged above the ash discharge valve, so that the filter bag is prevented from falling off and falling into the ash bucket, the phenomenon that the motor is burnt out by the reducer due to the fact that the filter bag falls off and is blocked is avoided, and normal operation of the machine is guaranteed.

Furthermore, the access hole has been seted up to the outer wall of dust removal box, and the DN80 access hole is opened to the outer wall, and the maintenance personnel of being convenient for carry out the maintenance work of equipment.

To sum up, the utility model discloses a steam heating equipment carries out invariable 50 ℃ temperature blowback gas to the filter bag, strengthens the inside and outside electrostatic action of filter bag, improves the efficiency of dust absorption on the filter bag, can reduce the dust concentration of dusty flue gas by a relatively large margin, improves the ability that the amount of wind was handled to the dust remover, improves dust collection efficiency.
