Abstract
The invention provides a low-pressure long-bag pulse-jet bag dust collector which comprises an upper box, a middle box and an ash bucket part. An external filtering type structure is adopted, the lower part of a filtering bag is closed, and the upper part of the filtering bag is opened. For preventing the filtering bag from contracting in a working process, a bag cage is arranged in the filtering bag; dust-containing air enters from the lower end of the middle box, firstly passes through a rough metal filter screen in a buffering area and then penetrates through the filtering bag from outside to inside; and the dust is stopped outside the bag, and clean air upward flows in the filtering bag, reaches to the upper box through the bag opening and then is discharged from an air outlet. According to the invention, the self-consumption of a pulse-jet system is reduced by low-pressure pulses, so that the required air pressure can be reduced, the energy consumption can be reduced, the adaptability is higher, the low-pressure long-bag pulse-jet bag dust collector has the advantages especially for the situations of large air treating volume and narrow space, and the dust cleaning effect is excellent.
Description
Technical field
The present invention designs the technical field of dust separation, more particularly to a kind of long bag pulse dust collector working under low pressure.
Background technology
Recently as the enforcement of environmental protection new-standard, the smoke exhaust producing for various commercial production stoves, it is required to
Just can discharge after being processed, the raising of the accessory technology such as the appearance with high-quality filtrate and pulse valve, reliability
Increase, large-scale cleaner unit newly-built at present is all a lot of using bag collector, and the deashing side that these dust-precipitators are adopted
Formula in a pulsed fashion based on.Air quantity is big, SR is little, deashing is thorough, efficiency of dust collection is high because it is processed for pulse bag type dust collector
The advantages of, favored by users, be widely used in each enterprise.How to further investigate impulse bag further
The Cleaning mechanism of cleaner unit, is constantly optimized design and seems and be even more important.
Content of the invention
It is an object of the invention to overcoming the shortcoming of prior art, making a kind of compact conformation of offer, adapting to Wind Volume, low consumption
Can, adaptability is higher, a kind of high long bag pulse dust collector working under low pressure of deashing intensity.
Even if the realization of present invention scheme is as follows：
A kind of long bag pulse dust collector working under low pressure is made up of upper box, middle casing, ash bucket part, using outside filtering type structure, filters
The closing of bag bottom, upper opening.In order to prevent filter bag from shrinking in the course of the work, there is filter bag built-in marsupial cage.Dusty gas by
Middle lower box enters, and first passes through relief area and slightly imitates metal filter screen, then ecto-entad passes through filter bag.Dust is detained to bag
Outward, clean gas flow up in filter bag, and reach upper box via bag mouth, then discharge purify air (Fig. 1) by exhaust outlet.
The deashing of filter bag is carried out by pulse spraying equipment, with compressed air as source of the gas.When control system sends signal, it is contained in voltage stabilizing gas bag
On straight through pulse valve just open, calming the anger in abrupt release out in gas bag, and the nozzle from injection tube sends into every
In filter bag.Filter bag is subject to the impulse of deashing air-flow to vibrate, and filter bag wall obtains very big acceleration, so that dust layer is cleared filter
Bag, falls into ash bucket.
Beneficial effects of the present invention：
The big dust particle that the combination of metal filter screen and vibrating motor can effectively stop in smoke exhaust is slightly imitated in relief area,
Under the stop of metal filter screen, big dust particle can partly drop in ash bucket, partly has can opening of certain adhesiveness
Vibrating motor is allowed to drop in ash bucket.
Metal filter screen is linked with driving vibrator and partly can dismantle, the larger nothing of small part viscosity after a long time use
Method vibrations remove, and simply metal filter screen windage becomes big, reduces dust removing effects, can disassemble and be carried out.Extend
The service life of metal filter screen, improves and removes dust quantity, the service life of protection filter bag.
The present invention is relatively low in compressed air pressure used, is 0.2～0.5MPa, using electromagnetic impulse valve, filter bag length one
As be more than 5m, and process that air quantity is big and the narrow and small occasion in place, more show its superiority, and ash-removal effect is good.
Brief description
Fig. 1 is a kind of schematic diagram of long bag pulse dust collector working under low pressure of the present invention.
Specific embodiment
With reference to the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Ground description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on this
Embodiment in invention, the every other reality that those of ordinary skill in the art are obtained under the premise of not making creative work
Apply example, broadly fall into the scope of protection of the invention.
With reference to Fig. 1, long bag pulse dust collector working under low pressure is made up of upper box 3, middle casing, ash bucket 10 part, upper box 3
Composition in electromagnetic impulse valve 1, voltage stabilizing gas bag 2, injection tube 4 be connected, card 5, flower are set between upper box 2 and middle casing
Plate 5 hypomere links filter bag 7, is provided with filter bag frame 6, middle casing left bottom has air inlet, air inlet one upper lateral part inside filter bag
There are purified gas outlet, air inlet and purified gas outlet metallic plate to separate, metallic plate is provided with driving vibrations 9, drives
Electromagnetic shaker 9 links with promoting effect metal filter screen 8.
Preferably, described relief area is slightly imitated metal filter screen 8 and drives the combination of vibrator 9 can effectively stop cigarette
Big dust particle in dirt waste gas, under the stop of metal filter screen, big dust particle can partly drop in ash bucket, part
The vibrating motor of can opening having certain adhesiveness is allowed to drop in ash bucket 10, after the dust collection in ash bucket 10 is full, opens out
Grey valve 11 is cleared up.
Preferably, electromagnetic impulse valve 1 and voltage stabilizing gas bag 2 utilize the deashing to cleaner unit for the computer controller that PLC is movement
Carry out programme-control；Using constant pressure difference control mode, the pressure of compressed air bag 2 is relatively low, is 0.2～0.5MPa, has simultaneously
Time control function, optional by operator.
The real process of pulse dust cleaning can be described as：The pressure in filter bag 7 is made rapidly to increase in pulse dust cleaning air-flow, filter
Bag 7 rapid outward expansion, when bag wall expand into extreme position, very big tension force makes it be subject to strong impact shock, and obtains
Obtain maximum opposite acceleration thus starting inwardly to receive；But the dust layer being attached to filter bag surface is not subject to tension force effect, due to inertia
The effect of power and come off from filter bag, maximum opposite acceleration is bigger, and inertia is also bigger, and ash-removal effect is better.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification of being made, equivalent, improvement etc., should be included within the scope of the present invention.
