Abstract
The utility model discloses the cloth-bag-typed dust-removing equipment together with functions of removal of sulfur and fluorine, and a container for storing chemical powder is provided. The container is communicated with a compressed air source and is connected with a spray head arranged in the inner cavity of a work chamber of the bag-typed dust-removing equipment. Being put in the container, while in use, the chemical powder with which sulfur oxide and fluoride in the flue gas can chemically react to produce nonpoisonous chemical material is sprayed onto the surface of a cloth bag in the work chamber. With the utility model, the poisonous chemical material of sulfur and fluorine in the dust can be effectively removed, the service life of the dust-removing equipment can be considerably prolonged, the request of the content of sulfur and fluoric in the primary fuel for cement manufacture enterprises can be reduced, and the production cost can be reduced.
Description
Technical field:
The utility model relates to the bag-type dust equipment of manufacture of cement industry, the particularly equipment of desulfurization defluorination bag-type dust.
Background technology:
China's cement industry is a heavy polluter, and the waste water that produces in its production process, dust, pernicious gas efflux in a large number, has a strong impact on people's living environment, and environmental protection is very urgent.At present, the function of the cleaner that generally uses of cement industry only rests on the control dust concentration on this.Dust collection method commonly used is to use bag-type dust.Under system's main air blower effect, dusty gas enters air inlet pipe through flue, enter deduster by top, the part particle is because inertia directly falls into ash bucket, and all the other cross cloth after the air bleeding valve exhaust duct enters atmosphere by exhaust blower through cloth bag, along with the prolongation of filtration time, dust layer on the cloth bag is constantly long-pending thick, the resistance of cleaner constantly rises, and when equipment resistance rose to setting value, deashing device began to carry out deashing.During deashing, compressed air or blowback air pass through each pulse valve or blowback air-valve in order with the extremely very brief time, make cloth bag produce vibration rapidly through winding-up or blowback, be stripped from attached to the dust on the cloth bag outer surface and fall into ash bucket, concentrate by grey quarrel again and discharge.In existing sack cleaner, because sulphur, fluorine are mainly with SO in the dusty gas
2, SO
3, the HF gas form exists, behind the cloth bag filtration, SO
2, SO
3, HF gas can not be retained down, and has only particles such as dust to be retained down behind the cloth bag filtration, and SO
2, SO
3, HF gas is through cloth bag, discharges deduster, SO with air-flow
2, SO
3, toxic gas such as HF also is discharged in the atmosphere, causes air pollution.
The utility model content:
The purpose of this utility model is to overcome above-mentioned deficiency, proposes a kind of bag-type dust collector that can effectively remove noxious material sulphur and fluorine in the dust.
The utility model technical solution is: contain the container of depositing chemical powder, container and compressed air source communicate, also be provided with the tube connector of the operating room's inner chamber that leads to sack cleaner on the container, the port of export of tube connector is equipped with shower nozzle, and shower nozzle places operating room's inner chamber of sack cleaner.
Between compressed air inlet and container, be provided with controllable valve.
On the tube connector between the operating room of container and sack cleaner, controllable valve is housed.
Adopt the utility model, can effectively remove noxious material sulphur and fluorine in the dust, have higher desulfurization defluorination efficiency of dust collection, gas after treatment meets the environmental protection new-standard GB4915-2004 that country formulates, and has reduced steam, SO
2, SO
3, harmful substance such as HF is to the corrosion of cleaner, prolonged the service life of cleaner greatly, reduced maintenance cost, also reduces the content requirement of cement production enterprise to sulphur in the crude fuel and fluorine, reduces production cost.
Description of drawings:
Accompanying drawing has provided an embodiment of the present utility model:
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: 1--dusty gas inlet; The 2--compressed air inlet; The 3--controllable valve; The 4--charge door; The 5--container; The 6--level-sensing device; The 7--tube connector; The 8--controllable valve; The 9--shower nozzle; The 10--operating room; The 11--dust-removal cloth-bag.
The specific embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:
Contain the container 5 of depositing chemical powder, container 5 is arranged on the top of sack cleaner, the top of container 5 is provided with charge door 4, charge door 4 is provided with capping, gamma-rays level-sensing device 6 is installed in the container 5, container 5 interlinks through controllable valve 3 and with compressed air inlet 2, and control to adjust its required pressure by control system, container 5 bottoms also are provided with the many tube connectors 7 that lead to operating room's 10 inner chambers of sack cleaner, controllable valve 8 is housed on the tube connector 7, the port of export of tube connector 7 is equipped with shower nozzle 9, and shower nozzle 9 places the inner chamber of the operating room 10 of sack cleaner.
When using the utility model, earlier operating room's 10 inner chambers of sack cleaner are carried out deashing and handle, again can with the SO in the flue gas
2, SO
3Carry out chemical reaction with HF and generate the chemical powder CaO of nontoxic chemical substance in charge door 4 adding containers 5, compressed air from compressed air inlet 2 through controllable valve 3 in tube connector 7 enters container 5, under control system control, the CaO powder is gone into intact clearly ash through controllable valve 8 force feeds, in the operating room 10 of certain sack cleaner after the ash fall, through shower nozzle 9 ejections, be sprayed on the surface of the cloth bag 11 in the operating room 10 of sack cleaner, because the homogenizing of shower nozzle, the gravity effect of peptizaiton and CaO powder, CaO powder will stick on the surface of the cloth bag 11 in the operating room of sack cleaner equably.At this moment, control system is sent instruction, and this chamber enters the filtration state, and the steam in the flue gas at first reacts with the CaO that sticks to the cloth bag surface, generates Ca (OH)
2, the Ca of generation (OH)
2Again with flue gas in SO
2, SO
3, HF reacts, and generates CaSO respectively
3, CaSO
4, CaF
2Part big dust particle in the flue gas is because the gravity effect directly falls into ash bucket, and the parts of fine granule dust also is being attracted under the effect of air-flow on the cloth bag 11, the dust on cloth bag 11 surfaces and reaction product CaSO
3, CaSO
4, CaF
2Cumulative, the running resistance of equipment increases gradually, and when surpassing setting value, control system is sent instruction and carried out deashing, reactant CaSO
3, CaSO
4, CaF
2, and the dust that is adsorbed on the cloth bag 11 gone into ash bucket clearly, by ash-discharging device regularly or draw off continuously, the clean gas after cloth bag 11 filters is discharged by discharge pipe.After clear intact ash, ash fall, control system is sent instruction, once more CaO powder force feed is gone into this operating room 10, repeats the above-mentioned course of work, goes round and begins again.
