Description
Technical field
The technical program belongs to Environmental-protecting dust-removing technical field, specifically a kind of low-pressure jet pulse bag type dust catcher.
Background technology
Bag filter is to apply dust removal and filtration equipment more widely.Bag filter runs into many problems, and on filter bag, adhesive dust is more, brings the problem that dust removal and filtration efficiency is lower.In order to address this problem, in prior art, the general mode that adopts blowing device to blow to reverse impulse in filter bag 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 blowing down on filter bag just needs more intense air pulse, just higher to the power requirement of blowing device 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 multiple;
Upper box and middle casing are separate, between them, isolate by filter bag; Each filter bag opening up, and the openend of filter bag is connected with upper box, and 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 air port; The injection tube of described blowing device, above each filter bag, has multiple winding-ups mouthful in injection tube, and each winding-up mouth is respectively towards the openend of a filter bag; In described ash bucket, be also provided with deflector, the opening direction of deflector in-plane and gas approach acutangulates.
Dusty gas is entered by flue gas air port, and the deflector in ash flue bucket makes part big dust particle in gas be separated by inertia force effect, directly falls into ash bucket.The dust granules of filter bag filtering area that dusty gas enters 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 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 feature of the technical program is that cleaner is unit-combination type, can form plurality of specifications according to element number.Cleaner adopts high-effect, low consumed blowing device, has 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 the industry such as cement, electric power.Cleaner is lightweight, take up an area less, cost is low.
Accompanying drawing explanation
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 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 multiple;
Upper box and middle casing are separate, between them, isolate by filter bag; Each filter bag opening up, and the openend of filter bag is connected with upper box, and 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 air port; The injection tube of described blowing device, above each filter bag, has multiple winding-ups mouthful in injection tube, and 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 ash bucket blanking port.
Work principle of filter:
Dusty gas is entered by ash bucket gas approach, and the deflector in ash flue bucket makes part big dust particle in gas be separated by 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 is through filter bag, and dust is delayed at filter bag outer surface.Purified gas, after filter pocket mouths enters upper box, then is discharged by air outlet.
