Each dust collector unit comprises a jetting device, an upper box body, a middle box body, a plurality of filtering bags, a flow guide plate, a dust hopper and a dust discharging device, wherein the upper box body and the middle box body are independent from each other and are separated from each other by the filtering bags; the opening of each filtering bag is upward and the opening end of each filtering bag is connected with the upper box body; a cavity of each filtering bag is communicated with the upper box body; each filtering bag body is located inside the middle box body; the dust hopper is connected to the bottom of the middle box body; the bottom of the dust hopper is connected with the dust discharging device; the flue gas inlet is formed in the side surface of the dust hopper; the air outlet is formed in the side surface of the upper box body; a jetting pipe of the jetting device is arranged above all the filtering bags and is provided with a plurality of jetting nozzles; the jetting nozzles respectively face the opening ends of the corresponding filtering bags; the dust hopper is also internally provided with the flow guide plate; and the plane direction of the flow guide plate and the opening direction of the flue gas inlet form an acute angle. The dust collector has the characteristics of being in a unit-combination type and in multiple specifications according to the quantity of units.

Description

Low-pressure jet pulse bag type dust catcher
Technical field
The technical program belongs to the Environmental-protecting dust-removing technical field, specifically a kind of low-pressure jet pulse bag type dust catcher.
Background technology
Bag filter is to use dust removal and filtration equipment more widely.Bag filter runs into many problems, and on filter bag, adhesive dust is more, brings the lower problem of dust removal and filtration efficient.In order to address this problem, in prior art, the general mode that adopts blowing device reverse impulse in the filter bag to blow is removed the dust on filter bag.The dust-precipitator of this mode need to adopt compressed air, blows afloat mouth, impulse valve and control appliance etc.For large-scale application scenarios, dust is larger, if the dust that blows down on filter bag just needs more intense air pulse, the power requirement to blowing device is just higher like this.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the technical program proposes a kind of new low-pressure jet pulse bag type dust catcher, it is characterized in that comprising one or more identical deduster unit, and the gas approach of each deduster unit is connected respectively with air outlet; For a deduster unit, comprise blowing device, upper box, middle casing, filter bag, deflector, ash bucket and ash-discharging device; Described filter bag has a plurality of;
Upper box and middle casing are separate, isolate by filter bag between them; Each filter bag opening up, and the openend of filter bag is connected with upper box, and the filter bag inner chamber is communicated with upper box; The bag of each filter bag is in middle casing; Ash bucket is connected to the bottom of middle casing, and the bottom of ash bucket is connected with ash-discharging device; Gas approach is offered in the side of described ash bucket, and the side opening of upper box sets out the air port; The injection tube of described blowing device has a plurality of winding-ups mouthful on injection tube above each filter bag, each winding-up mouth is respectively towards the openend of a filter bag; Also be provided with deflector in described ash bucket, the opening direction of deflector in-plane and gas approach acutangulates.
Dusty gas is entered by the flue gas air port, and the deflector in ash flue bucket makes that in gas, the part big dust particle is separated by the inertia force effect, directly falls into ash bucket.The dust granules of filter bag filtering area that dusty gas enters the raising middle flask body after by ash bucket is less, can be blowed with comparalive ease device and remove, and makes the blow gas pressure of blowing device and pulse duration require to reduce.
The external support that is connected with of described raising middle flask.Described ash bucket outer wall is connected with hopper wall vibrator.Described ash-discharging device is star-shaped ash unloading valve or the conveying worm that is connected to the ash bucket blanking port.
This low-pressure jet pulse bag type dust catcher is that a kind of efficiency of dust collection is high, stable, dependable performance, large-scale cleaner easy to maintenance, can be widely used in the dust pelletizing system of all trades and professions such as casting, metallurgy, machinery, electric power, building materials, ore, cement, chemical industry.
The characteristics of the technical program are that cleaner is unit-combination type, can consist of plurality of specifications according to element number.Cleaner adopts high-effect, low consumed blowing device, realized the injection method of low-pressure, short pulse.Can reduce kinetic equation loss, extend the service life of consumable accessory.Filter bag adopts film composite filtering material.It not only can improve filtration velocity, and cleaner resistance reduction, stable.Make the dedusting of the dusty gas of cleaner particularly suitable high humidity, high temperature, as industries such as cement, electric power.Cleaner is lightweight, take up an area less, cost is low.
Description of drawings
Fig. 1 is the structural representation of the technical program;
In figure, blowing device 1, upper box 2, middle casing 3, filter bag 4, deflector 5, ash bucket 6, ash-discharging device 7, support 8, injection tube 9, nozzle 10.
The specific embodiment
The technical program is further illustrated as follows below in conjunction with accompanying drawing and the specific embodiment:
A kind of new low-pressure jet pulse bag type dust catcher is characterized in that comprising one or more identical deduster unit, and the gas approach of each deduster unit is connected respectively with air outlet; For a deduster unit, comprise blowing device, upper box, middle casing, filter bag, deflector, ash bucket and ash-discharging device; Described filter bag has a plurality of;
Upper box and middle casing are separate, isolate by filter bag between them; Each filter bag opening up, and the openend of filter bag is connected with upper box, and the filter bag inner chamber is communicated with upper box; The bag of each filter bag is in middle casing; Ash bucket is connected to the bottom of middle casing, and the bottom of ash bucket is connected with ash-discharging device; Gas approach is offered in the side of described ash bucket, and the side opening of upper box sets out the air port; The injection tube of described blowing device has a plurality of winding-ups mouthful on injection tube above each filter bag, each winding-up mouth is respectively towards the openend of a filter bag;
The external support that is connected with of described raising middle flask.Described ash bucket outer wall is connected with hopper wall vibrator.Described ash-discharging device is star-shaped ash unloading valve or the conveying worm that is connected to the ash bucket blanking port.
Work principle of filter:
Dusty gas is entered by the ash bucket gas approach, and the deflector in ash flue bucket makes that in gas, the part big dust particle is separated by the inertia force effect, directly falls into ash bucket.Dusty gas enters the filter bag filtering area of raising middle flask body after by ash bucket, and gas passes filter bag, and dust is delayed at the filter bag outer surface.Purified gas then is discharged by air outlet after filter pocket mouths enters upper box.
