Abstract
The utility model provides a dust-removing device for a cement vertical kiln, which is composed of a spraying dust remover, an ultrafine dust remover, a buffering and dewatering chamber, a sedimentation dust remover and a dust and water separating device. The spraying dust remover, the ultrafine dust remover and the buffering and dewatering chamber are combined together from bottom to top. The dust and water separating device is connected with the bottom part of the spraying dust remover through a pipeline. The utility model has the advantages of reasonable design, simple structure, convenient use, good dust removing effect, no generation of secondary pollution, etc.
Description
The utility model relates to a kind of dust arrester, specifically a kind of Wet-way dust-collector that is used for cement in vertical kiln.
Usually cement in vertical kiln is the comparatively serious industrial equipment of a kind of environmental pollution, aborning mostly the exhaust emission that environment produced is by electric dust collector the exhaust opening of cement in vertical kiln to be carried out electric precipitation in order to administer cement in vertical kiln, but in use existing deficiency is that power consumption is big, dust removing effects difference etc.
The purpose of this utility model provides a kind of simple in structure, good energy-conserving effect, cement in vertical kiln dust arrester that operating cost is low.
The purpose of this utility model realizes in the following manner, in dust arrester, form the flue dust that multistage water spray gets rid of shaft kiln and carry out the washing, purifying dedusting by spray deduster, superfine deduster, buffering dewatering station, expansion chamber deduster, by seperator of ash and water mud and moisture being can be used as raw material from, the mud of recovery again sends nodulizer back to and makes ball again and advance shaft kiln calcination and become clinker.
The technical characterstic of equipment
1. supply with spray deduster, superfine deduster, cushion shower nozzle water supply the carrying out water mist dust-removing in dewatering station, the expansion chamber deduster by two cover water systems.Wherein a cover supplies water for the shower nozzle in expansion chamber deduster and the ultra tiny deduster through high-pressure pump for clear water.Another set of is that recirculated water after the Ash Water Separator uses for the shower nozzle in the spray deduster through the water pump group.Shaft kiln is forged the grog ash-laden gas, enters the expansion chamber deduster through passage, and the multilayer fine atomizer that divides into groups is housed in the expansion chamber deduster.By water inlet pipe, flow divider valve is supplied with the shower nozzle spraying to high-pressure pump with the high pressure clear water.Dust serves as that nuclear condenses by in the process of mist layer with the kiln ash, and the top layer is by moistening, cooling, and the sedimentation of growing up that bonds is mutually discharged through ash discharge, forms the wet dried row that receives.Flue-gas temperature changes greatly in order to solve, water evaporation problem of non-uniform, detect the variations in temperature of expansion chamber deduster in the equipment by thermocouple, realize the proportional relation that flue-gas temperature raises, injection flow rate increases by the flow solenoid valve of electronic temperature control unit control water inlet pipe then.Making gathers dust reaches best.
2. spray deduster is closed original shaft kiln chimney, and the flue gas after the dedusting of expansion chamber deduster enters spray deduster, in this dedusting different angles is housed, different atomizing half warps, the atomizer that multilayer is up sprayed.The water pump group is the recirculated water that has certain pressure, supply with atomizer by water inlet pipe, ball valve, in spray deduster, form the sealing atomizing layer, when ash-laden gas enters with certain flow rate, soot dust granule is atomized layer, after the wetting seizure, condense and advance the Ash Water Separator device with current and handle.
3. ultra tiny deduster, ultra tiny deduster is provided with baffle-box, water-supply-pipe, import, ultra tiny shower nozzle and atomizer and forms, flue gas is after the dedusting of preceding twice dust pelletizing system, carry a small amount of fine flue dust secretly and enter ultra tiny deduster, clear water is supplied with ultra tiny shower nozzle through high-pressure pump, water-supply-pipe, forms ultra tiny atomizing layer, because after flue gas enters ultra tiny dust pelletizing system, the cigarette prompt drop is low, helps that fine flue dust fully contacts with fog, cohesion, sedimentation fall.
In order to prevent that fine flue dust from floating,, give atomizer for recirculated water in the above by the water pump group, increase two-layer atomizing layer, stopped the rising of floating flue dust.Because shower nozzle spray direction is identical with the flue gas ascent direction, the resistance that fog produces and the climbing power of shower nozzle band flue gas offset basically, kiln face nest cigarette can not occur, thereby realize the continuous dedusting in three lines of defence.
4. the Ash Water Separator device is made up of seperator of ash and water, mud scraper two big parts, the grey water mixed liquid that dedusting is fallen flows into dirty mouthful of going into of seperator of ash and water along the chimney wall, in order to reduce the kinetic energy that buck falls, accelerate mud at bottom precipitation, control flow with flashboard, when making the dirty sewage pipe of sewage bottom, current are steady.Because sewage pipe and seperator of ash and water sectional area ratio differ manyfold, effluent flow rate has also reduced manyfold, form the approximate steady water surface, through natural sedimentation, mud flows to the mud mouth along seperator of ash and water cone wall, enter the mud scraper bottom, scrape through the scraper plate machine through mud and incorporate former technology and complete set equipment (biaxial rneader, pan-pelletizer) recycling into; Clear water is used for the spraying and dust-removing system circulation.
Owing to contain lime, dust, SO in the recirculated water
2And HF, absorb each other between them, clear up mutually, keep recirculated water and be neutral substantially, solved desulfurization, the defluorinate problem of flue gas.
Mud scraper is to drag reductor by motor to drive the driving-chain rotation, and many scraper plates are housed on the driving-chain, and scraper plate is scraped mud and up moved.Because the mud scraper outlet is higher than seperator of ash and water overflow plane, muddy water separately, mud enters former technology and complete set equipment (biaxial rneader, pan-pelletizer) by mud discharging mouth and recycles.
5., buffering dewatering station: flue gas after being purified enters buffering dewatering station, utilizes to change velocity of flue gas, and the gas-water separation principle is carried out processed.Flue gas after the dedusting enters sky after the dehydration of buffering dewatering system.
Accompanying drawing is the overall structure schematic diagram of cement in vertical kiln dust arrester.
Explain below with reference to Figure of description cement in vertical kiln dust arrester of the present utility model being done.
Cement in vertical kiln dust arrester of the present utility model, its structure is to be made of spray deduster 1, superfine deduster 2, buffering dewatering station 3, expansion chamber deduster 4 and Ash Water Separator device, spray deduster 1, superfine deduster 2 and buffering dewatering station 3 combine from bottom to top, spray deduster 1 joins with shaft kiln chimney 6 by leading smoke pipe 5, expansion chamber deduster 4 is connected on the below of shaft kiln chimney 6, and the Ash Water Separator device is by the bottom connection of pipeline 7 with spray deduster 1.
Be provided with atomizing spray 8 in spray deduster 1, superfine deduster 2 and expansion chamber deduster 4, atomizing spray head 8 joins by water pipe and water pump 9.
