Description

A kind of uniform pulse backblowing deduster of air flow method

Technical field

The utility model belongs to environmental protection machinery more particularly to a kind of uniform pulse backblowing deduster of air flow method.

Background technique

In the industrial equipments such as mixing plant, various types cleaner is commonly used, the uniform pulse backblowing of air flow method removes Dirt device is a kind of high-effective dust-removing equipment that can be realized automatic ash removing function.Chief component 1- blower as shown in Figure 1:；2- Pulse jet system；3- cabinet；4- filter core；5- blast pipe；6- ash hole.Main operational principle are as follows: by the air inducing of blower 1, Gas by the external world with dust sucks deduster from blast pipe 5, and the air with dust filters in cabinet 3 through filtration core 4, passes through Pure air is discharged from blower after filter；Pulse jet system 2 is grouped to the inside of filter core 4 by way of pulse and sprays into a large amount of skies Gas is discharged so that the dust for accumulating in cartridge surface be made to fall off from ash hole 6.

In the uniform pulse backblowing deduster of currently used air flow method, the structure as a whole of cabinet 3 is each to filter Core close-packed arrays in cabinet.When carrying out blowback to a part of filter core, blower is just drawn pulse jet system simultaneously Wind is easy to be adsorbed in neighbouring filter core again so that the dust to fall off from the filter core by blowback is blown to neighbouring filter core, from And it is easy obstruction filter core, reduce efficiency of dust collection.Thus as shown in Fig. 2, I am for a kind of pulse backblowing of above situation application Deduster, the patent No. 201620544767, by increasing and being arranged partition；Cabinet is isolated into several warehouses by partition, thus anti- The dust that anti-avulsion is fallen is adsorbed again by neighbouring filter core, improves dust-collecting efficiency.But in use discovery, due to be provided with every Plate causes the negative pressure being subject to the warehouse of blower face at middle part big, therefore the dust absorbed is more, and filter core service life is short；And The negative pressure that the warehouse of periphery is subject to is small, therefore the dust absorbed is few, long service life, since filter core service life is irregular, This causes pulse backblowing deduster needs often to be dismantled to replace filter core, wastes time.Furthermore, while have pulse jet system, but It is or having dust gradually accumulates, reduces the service life of deduster, therefore it is a kind of that reduction, which enters the dust quantity of filter core, The method for effectively increasing deduster service life.

Utility model content

To solve the above problems, the utility model provides a kind of uniform pulse backblowing deduster of air flow method.This reality With the novel use time for extending filter core by setting airflow-distribution board and buffer air chamber, reduce the replacement number of filter core simultaneously Extend the service life of deduster.

To reach above-mentioned technical effect, the technical solution of the utility model is:

A kind of uniform pulse backblowing deduster of air flow method, including cabinet, cabinet are equipped with blast pipe and ash hole；Case Body is connected with blower；Pulse jet system is equipped between ash hole and blower, pulse jet system is connected with several filter cores, described Partition is equipped between filter core；Cabinet is isolated into several warehouses by partition, and the top of the box is equipped with airflow-distribution board, air-flow point Several air flow method holes are formed on fabric swatch；The upper surface of the airflow-distribution board is recessed upper arc groove, airflow-distribution board Lower surface be fovea superior arc lower arcuate slot.

It is further to improve, buffer air chamber, buffer air chamber left side and blast pipe connectivity part are communicated in the middle part of the blast pipe Filter screen is installed.

Further to improve, the buffer air chamber bottom opening is simultaneously threaded with capping, and capping internal shaping has sink.

Further to improve, the pulse jet device includes several pulse jet devices, and each warehouse is equipped with a pulse spray Blow device.

Further to improve, the partition is two, and cabinet is isolated into warehouse one, warehouse two and warehouse three by partition.

The utility model extends the use time of filter core by setting airflow-distribution board and buffer air chamber, reduces filter core Replacement number and extend the service life of deduster.

Specific embodiment

The technical solution of the utility model is illustrated below by way of specific embodiment and in conjunction with attached drawing.

Embodiment 1

A kind of uniform pulse backblowing deduster of air flow method as shown in Figure 3 includes: 1- blower；2- pulse jet system System；3- cabinet；4- filter core；5- blast pipe；6- ash hole；7- airflow-distribution board；71- air flow method hole；The upper arc groove of 72-；73- Lower arcuate slot；8- buffer air chamber；9- filter screen；10- capping；11- sink.Increase partition 31 inside cabinet 3, by deduster case Body is isolated into multiple small warehouses, and (warehouse 1, warehouse 2 33 and warehouse 3 are 34)；Filter core is distributed in each warehouse, each warehouse Respectively correspond a pulse jet device；Blower 1 carries out air inducing to entire deduster, and band dusty air is entered by blast pipe 5 to be removed Dirt device, after in different warehouses pass through filter element filtering, pure air pass through blower after deduster is discharged, dust is adhered to each warehouse Deduster surface；Pulse jet device point warehouse successively carries out blowback, when pulse jet device carries out blowback to one of warehouse, Dust falls off from the warehouse filter core, falls to the discharge of ash hole 6；Due to being stopped by partition 31, dust will not be in the mistake that fall that recoils It is adsorbed in journey by neighbouring filter core.

In order to which the negative pressure for guaranteeing that each warehouse is subject to is consistent, airflow-distribution board 7, airflow-distribution board 7 are installed at the top of cabinet 3 On be formed with several air flow method holes 71；The upper surface of the airflow-distribution board 7 is recessed upper arc groove 72, airflow-distribution board 7 lower surface is the arc lower arcuate slot 73 of fovea superior, guarantees that each warehouse is subject to negative by the distribution in air flow method hole 71 in this way Pressure is consistent, and the setting of upper arc groove 72 and lower arcuate slot 73 is so that air flow method plate surface has certain gradient, it is not easy to Accumulate dust.

In order to reduce the dust inlet in deduster, buffer air chamber 8,8 left side of buffer air chamber are connected in the middle part of blast pipe 5 Filter screen 9 is installed with 5 connectivity part of blast pipe.8 bottom opening of buffer air chamber is simultaneously threaded with capping 10, covers 10 internal shapings There is sink 11.Before gas enters deduster in this way, line passes through buffer air chamber 8, since the internal diameter of buffer air chamber is greater than blast pipe 5, Flowing velocity slows down air-flow here, and big dust granule is easy to deposit here, while filter screen 9 is arranged, and reinforces big ash The deposition of dirt particle, and the capping 10 by being placed with water adheres to dust granule, only needs to jack up disassembly capping in this way and rinses Change the i.e. sustainable adhering dust particle of water.It is greatly reduced in this way into the dust at filter element of duster, substantially increases filter core And the service life of deduster.

It above are only one of the utility model specific guiding embodiment, but the design concept of the utility model not office It is limited to this, all non-essential modifications to the present invention made by this concept should belong to the guarantor for invading the utility model Protect the behavior of range.
