Abstract
The utility model provides a gas box pulse spraying bag-typed dust catcher. The utility model is provided with a shell with an ash receiving hopper; the shell is internally divided into a gas box, an exhaust room, a bypass air path and a group of smoke gas room by clapboards; a group of filter bags hang on an upper clapboard in the smoke gas room; the gas box is internally provided with an exhaust valve and a pulse spraying valve; under the pumping action of a wind guide main pipe, the powder ashes and dust slag impurities are filtrated and blocked by the filter bags; the clean air after filtration enters the exhaust room through the gas box and is exhausted by the wind guide main pipe; the instant high pressure airflow sprayed by the pulse spraying valve can blow the powder ashes and dust slag impurities adsorbed on the external surface of the filter bag down to an ash receiving hopper, so as to realize the object of cleaning and recycling the ashes. The utility model has the advantages of novel design, low manufacture cost, high dedusting efficiency, good continuous and stable operation performance, extremely convenient filter bag replacement and maintenance management, and having extremely good generalization application prospect.
Description
Technical field:
The utility model relates to and a kind of industrial dust, ash-laden gas is carried out purified treatment and can collect the device of powder ash, the reuse of dirt slag waste material, specifically a kind of air box pulse spraying bag filter, it is particularly suitable for manufacture of cement factory and discharging dust such as iron and steel, electric power and chemical industry, manufacturing enterprise that exhaust gas volumn is bigger installs and uses.
Background technology:
We know; A large amount of industrial dust and ash-laden gas can discharge in the enterprise that produces cement, iron and steel, chemical products, harmful substances such as industrial dust that these enterprises discharge and ash-laden gas meeting severe contamination air, the environment space that people are depended on for existence causes huge pollution.China environmental protection administrative service division has force these enterprises and must handle and up to standardly can allow discharging the industrial waste gas that is discharged, to industrial waste gas handle can not be up to standard enterprise will limit output to being forced to property even close stopping production.Up to now, in the most enterprises of China the processing of industrial dust and ash-laden gas is remained and to continue to use traditional moisture film water-bath dedusting technology, this moisture film water-bath dedusting technology is that harmful substances such as dust flue gas is soluble in water, though it can alleviate the industrial waste gas that the discharged pollution level to air, but this moisture film water-bath dedusting technology one-time investment expense is higher, water consumption is bigger in running, directly cause the processing cost of industrial waste gas to increase, the management and maintenance expense also increases thereupon, and, work as dust, discharging can form new industrial wastes pollution sources after harmful substances such as flue gas are water-soluble, once can cause huge pollution to the ecological environment of river basin again.Obviously, this moisture film water-bath dedusting technology only is a kind of temporary measure that table does not effect a permanent cure of controlling.Recently, in the dust collection device industry, released a kind of industrial filter bag dust-precipitator again, in general, this filter bag dust-precipitator can satisfy the requirement that slighter dust flue gas is handled, but, in the higher occasion of dust flue gas concentration, the phenomenon of filter bag appears stopping up in actual use easily, cause the air permeance resistance utmost point that gathers dust of filter bag to increase severely greatly, shortened the Acceptable life of filter bag greatly, have a strong impact on dust collection effect, the continous-stable runnability of dust collection device is reduced greatly, and it is not enough in use also to exist the deashing dynamics, the ash discharge deashing is difficulty comparatively, change the outfit filter bag and maintenance management also very the trouble.
Summary of the invention:
The utility model be propose on the basis of existing technology a kind of simple in structure, novel in design, cost of manufacture is low, the dust-collecting efficiency height, and the continous-stable runnability is good, filter bag and maintenance management air box pulse spraying bag filter extremely easily changes the outfit, it is that the top is equipped with cover, the bottom is equipped with the housing that connects ash bucket, top at housing is separated into gas tank by upper spacer, in housing, be separated out the exhaust chamber of sealing by midfeather, be separated into one group of flue dust chamber by one group of diaphragm plate, the blast pipe that is installed on exhaust chamber is connected with the air inducing person in charge, done one group of air release valve hole at the top of exhaust chamber, being threaded onto the guiding distributor pipe that connects in the ash bucket is connected with the flue dust person in charge, it is characterized in that one group of filter bag that is set in the cage skeleton mounts that to be suspended in one group of flue dust in upper spacer indoor, in gas tank, one group of drain tap by the cylinder interlock is installed with one group of corresponding position of air release valve hole, in gas tank, set of pulses snifting valve is installed with corresponding position, one group of flue dust chamber, during its work, be installed on each dust by distribution, the sweep-up pipe of smoke pollution source origination point imports the flue dust person in charge with dust and ash-laden gas, it is indoor all to be distributed into one group of flue dust by the guiding distributor pipe again, under the swabbing action that air inducing is responsible for, the powder ash, dirt slag impurity is barred from the filter bag outer surface by being suspended in one group of indoor filter bag filtration of flue dust, clean air after the filtration enters the filter bag inner chamber, through gas tank, air release valve hole enters exhaust chamber, by discharging behind the blast pipe input air inducing person in charge, when the powder ash that is adsorbed in the filter bag outer surface, dirt slag impurity is thicker, when the air permeance resistance of filter bag increases, at this moment cylinder operation promotes drain tap and closes air release valve hole, spray the instantaneous pressure air-flow by set of pulses snifting valve to the filter bag inner chamber, the powder ash of filter bag outer surface will be adsorbed in, dirt slag impurity blows off and breaks away from the filter bag surface and crash into and connect in the ash bucket, the gather dust purpose of deashing of realization, thereupon, cylinder spurs drain tap again and opens the working cycles that air release valve hole promptly enters next filtration deashing.
The utility model also has following technical characterictic:
In exhaust chamber, be separated out the bypass gas circuit of sealing again by a pair of dividing plate, the air inlet pipe that is installed on the bypass gas circuit is connected with the flue dust person in charge, the escape pipe that is installed on the bypass gas circuit is connected with the air inducing person in charge, when needs change the outfit filter bag or complete machine when needing repairing, can use bypass gas circuit discharging flue gas, not influence the operate as normal of production system.
At the bottom device that connects ash bucket ash-valve is arranged, manually the time opening ash-valve is collected powder ash, the reuse of dirt slag, ash-valve also can be selected the quantitative open valve for use, when being deposited on the powder ash that connects ash bucket bottom, when dirt slag thing reaches the weight of setting, promptly opening ash discharge automatically and collect reuse.
