A kind of cabinet type deduster enhancing wind pressure
The utility model relates to dust catcher device field, specifically a kind of cabinet type deduster for enhancing wind pressure.
Deduster is setting that dust is separated from flue gas, and is common facility in boiler and industrial production, existing
Have and disclose the deduster of various structures in technology, such as CN202823075U discloses a kind of deduster, it will by mesh screen
Air and dust separation, and there is backflow structure, the backwash to mesh screen may be implemented, existing deduster has been made and has been changed
Into, but there are still some defects of current device, such as the air quantity of air intake vent to be affected by flue gas discharge rate, flue gas pressures
Have the defects that dedusting speed is slow, inefficiency when too small；Simultaneously for the flue gas containing bulky grain, by same strainer into
Row filtering, causes screen replacing frequent, and cost improves.
Utility model content
The technical problem to be solved by the utility model is to provide the cabinet type dedusters that one kind can enhance wind pressure, existing to solve
There is defect present in technology.
The technical solution that the utility model solves above-mentioned technical problem is as follows:
A kind of cabinet type deduster enhancing wind pressure, the electric cabinet including being located at cabinet body side, the electric cabinet control electricity
Machine rotation drives the blower filtered gas is discharged, and the side of opposite blower has smoke inlet in the cabinet body, and flue gas passes through
The smoke inlet is sent into filter cabin after entering pipeline, and the filter cabin has particle mesh screen and dust strainer, respectively to flue gas
In large particle and dust be filtered after be discharged through blower；The filter cabin is connected with compressed air inlet, the compression
Air intake pass through respectively the first electromagnetic valve, second solenoid valve door, third electromagnetic valve control switch pipeline and filter cabin
Connection, first electromagnetic valve, second solenoid valve door, third electromagnetic valve connect with electric cabinet and are controlled by it switch, institute
It states particle mesh screen and dust strainer two sides is respectively provided with guiding device, the dust fallen after filtering is imported in mud chamber, precipitating
There is the grey trolley connection below switchable baffle and cabinet body below room.
Further, the grey trolley is set in cabinet body lower cavity, and the cabinet door with good airproof performance is sealed,
Prevent dust from flying upward；The ash trolley has universal wheel, easy to remove.
Further, the pipeline and filter chamber connection position are provided with check valve, prevent gas backwash.
Further, the side of the cabinet body is provided with maintenance door, convenient to overhaul to deduster inside.
The beneficial effects of the utility model are: being provided with double-filtration net, classified filtering can be carried out to flue gas, reduced
Consumption to strainer；Meanwhile by being passed through compressed air in filter cabin, the rate of filtration can be accelerated, improved efficiency；Dedusting and recoil
Operation, which only needs to control the different electromagnetic valves of unlatching, to be carried out, easy to use；And the removable grey trolley of setting is convenient to clean
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model overlooking structure diagram；
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
As shown in Figs. 1-2, a kind of cabinet type deduster enhancing wind pressure, the electric cabinet 1 including being located at cabinet body side are described
Electric cabinet 1 controls the rotation of motor 2 to drive blower 3 to be discharged filtered gas, and the side in the cabinet body with respect to blower 3 has
Smoke inlet 5, flue gas are sent into filter cabin after the smoke inlet 5 enters pipeline, and the filter cabin has particle mesh screen 7 and powder
Dirt strainer 8, respectively in flue gas large particle and dust be filtered after be discharged through blower 3；The filter cabin is connected with pressure
Contracting air intake 4, the compressed air inlet 4 pass through the first electromagnetic valve 9, second solenoid valve door 10, third solenoid valve respectively
The pipeline of 11 control switches of door is connect with filter cabin, first electromagnetic valve 9, second solenoid valve door 10, third electromagnetic valve
11 connect with electric cabinet 1 and are controlled by it switch, and the particle mesh screen 7 and 8 two sides of dust strainer are respectively provided with guiding device, will
The dust fallen after filtering imports in mud chamber 12, with the grey trolley below switchable baffle and cabinet body below mud chamber 12
Further, the grey trolley 14 is set in cabinet body lower cavity, and the cabinet door 13 with good airproof performance carries out
Sealing, prevents dust from flying upward, and the ash trolley 14 has universal wheel 15, easy to remove.
Further, the pipeline and filter chamber connection position are provided with check valve 6, prevent gas backwash.
Further, the side of the cabinet body is provided with maintenance door 16, convenient to overhaul to deduster inside.
Specific work process: flue gas is after pipeline enters filter cabin, by compressed air inlet injecting compressed air, when into
When row dust removal operation, the first electromagnetic valve is controlled by electric cabinet and is opened, thus compressed air enters filter cabin, pressure in cabin is increased
By force, accelerate the rate of filtration, improve efficiency；When carrying out recoil cleaning operation, electric cabinet controls second solenoid valve door and third electricity
Magnetic valve working, compressed air carry out recoil operation to particle mesh screen and dust strainer respectively, the dust of attachment are blown off, dust
Enter in mud chamber through guiding device, after precipitation, dust is imported grey trolley by openable opening, periodically by grey trolley release into
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
