Abstract
The utility model relates to an environmental protection device in metallurgical, cement, chemical, mining and other enterprises, in particular to a pulse gas bag deduster for coal milling specially. Above an upper gas tank is provided with a plurality of exaltation valves. A solenoid pulse valve is connected with an injection elbow, and both of which are arranged in the exaltation valve. Above the upper gas tank is provided with a compressed gas pipe which is connected with a plurality of exaltation valves respectively. A plurality of dust-sieving cloth bags is arranged in a lower gas tank. An air inlet and an air outlet are arranged in the two sides of the lower gas tank. Inside the lower gas tank is provided with gas chamber clapboard which is deposited aslant. An explosion vent is arranged in the back of the lower gas tank. A hole door is arranged in the middle of a ash bucket and a discharge device is arranged under the ash bucket. The utility model is characterized in that the pulse gas bag deduster is compact in structure, small in floor space, powerful in dedusting, good in effect and long in life-span.
Description
Technical field
The utility model relates to the environmental protection equipment of enterprises such as metallurgy, cement, chemical industry, mine, relates in particular to a kind of coal and grinds special-purpose air box impulse bag-type dust remover.
Background technology
In the past cement production enterprise, the dedusting of various coal mills, because deduster is when control of dust is too much under negative pressure or high temperature action, overstep the extreme limit and easily produce burning or blast, set up the burn-proof and explosion prevention measure, the cleaner structure also will be made corresponding change, thereby not too is fit to the dedusting of dust content extra-high-speed.And there is the defective that air leak rate of air curtain height, the easy dust stratification in corner, cloth bag service life is short, equipment resistance is big, ash-removal effect is poor, cleaning efficiency is low in sack cleaner, also there is the deashing kinetic energy deficiency of chamber-dividing counter-blowing in it, reaches jetting deashing and filters the defective of carrying out simultaneously.
Summary of the invention
The purpose of this utility model is in order to overcome deficiency of the prior art, and a kind of rational in infrastructure, pulse unit sack cleaner that cleaning efficiency is high is provided.
For achieving the above object, the utility model adopts following technical scheme to realize:
Coal grinds special-purpose air box impulse bag-type dust remover, it is characterized in that: go up the gas tank top front face and be provided with several lift valves, electromagnetic impulse valve is connected with the winding-up elbow, electromagnetic impulse valve is arranged on the lift valve with the winding-up elbow, and last gas tank top is provided with the Compressed Gas pipeline and is connected with several lift valves respectively; Following gas tank inside is provided with several filter dirt cloth bags, and following gas tank both sides are respectively equipped with air inlet and air outlet, are provided with gas chamber clapboard in the following gas tank, and this gas chamber clapboard tilts to place, and following gas tank back is provided with explosion relief door; The middle part of ash bucket is provided with door to access, and the ash bucket bottom is provided with discharger.
The hopper slope of described ash bucket 〉=65 °.
Compared with prior art, the utility model has the advantages that:
1, this product has locellus global purge dust and adopts big specification electromagnetic impulse valve dust out form, have compact conformation, floor space little, remove that grey ability is strong, effective, the advantage of long service life;
2, this product integrates chamber-dividing counter-blowing and winding-up pulse bag type dust collector, has overcome the shortcoming of the deashing kinetic energy deficiency of chamber-dividing counter-blowing;
3, this product is applicable to the improvement of high concentrate dust, can simplify the technological process for the treatment of flour dust, reduces equipment investment;
4, this equipment enhanced leaktightness avoids in the system oxygen content too high and cause dust explosion;
5, this product has explosion prevention function, and safe explosion relief door is compared with explosion proof door, has both reduced cost, and is safe and reliable again;
6, ash bucket is designed to hopper slope 〉=65 and ° avoids the turning dust stratification, and cause spontaneous combustion.
Description of drawings
Fig. 1 is a structural front view of the present utility model;
Fig. 2 is a structure left view of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
See Fig. 1, Fig. 2, coal grinds special-purpose air box impulse bag-type dust remover, last gas tank 4 top front face are provided with several lift valves 3, electromagnetic impulse valve 1 is connected with winding-up elbow 2, electromagnetic impulse valve 1 is arranged on the lift valve 3 with winding-up elbow 2, and last gas tank 4 tops are provided with Compressed Gas pipeline 15 and are connected with several lift valves 3 respectively; Following gas tank 7 inside are provided with several filter dirt cloth bags 5, and following gas tank 7 both sides are respectively equipped with air inlet 13 and air outlet 14, are provided with gas chamber clapboard 12 in the following gas tank 7, and this gas chamber clapboard tilts to place, and following gas tank 7 back are provided with explosion relief door 11; The middle part of ash bucket 8 is provided with door to access 9, and ash bucket 8 bottoms are provided with discharger 10.
When the outer surface dust that is attached to filter dirt cloth bag 5 increases, air communication is filtered dirt cloth bag 5 resistances and is constantly increased, when resistance increases to 1770Pa, the automated programming controller sends pulse signal, the first locellus lift valve 3 cuts out, cut off the air-flow that leads to first locellus, electromagnetic impulse valve 1 is opened simultaneously, high pressure air is blown in the filter dirt cloth bag 5 by the Venturi tube of winding-up elbow 2 through filter dirt cloth bag 5 inlets, filter dirt cloth bag 5 is sharply expanded, cause impact shock, make blow off 8 li in ash bucket of the dust that sticks to filter dirt cloth bag 5 outer surfaces, the first locellus lift valve 3 is opened afterwards; The automated programming controller is patrolled and examined processing successively to several locellus; When the control of dust of ash bucket 8 is too much, open discharger 10 dust discharges.
Claims (2)
