The flue gas removing device can remove flue gas generated during water quenching, can enable the quenching water to recycle, and greatly reduces waste of water resource and pollution to environment.
Description
Technical field
The present invention relates to the flue gas scavenge unit for water quenching of the flue gas produced when removing water quenching in quenching tower.
Background technology
Quenching tower is a hollow building, and the middle part of quenching tower is provided with spray equipment.Water quenching refers to that the spray equipment in quenching tower makes red-hot red Jiao's cooling become the method for normal temperature coke to the red-hot red Jiao's spray coke quenching water be placed on bottom quenching tower on coke quenching cart.When water quenching, coke quenching water meets red-hot red Jiao can produce a large amount of high-temperature flue gas, containing a large amount of steam and harmful substance in flue gas, usual flue gas can directly be discharged to air from the tower top outlet of quenching tower, so just serious pollution is caused to environment, and containing a large amount of steam in the flue gas of draining, also create the waste of water resource.
Summary of the invention
Technical problem to be solved by this invention is: the flue gas scavenge unit for water quenching providing a kind of flue gas produced when can remove water quenching in quenching tower.
In order to solve the problem, the technical solution adopted in the present invention is: for the flue gas scavenge unit of water quenching, comprise support, be characterized in: on support, be provided with the collecting hood that can shelter from quenching tower top exit, support is also provided with the flue that import is connected with collecting hood, the sidewall of flue is connected with deduster, blower fan in deduster by flue the flue gas inspiration deduster in collecting hood, the condenser pipe carrying out steam in condensation flue gas by passing into condensate liquid is also provided with in flue, between the deduster access port of condenser pipe on collecting hood and flue sidewall, flue gas is first after the condensation of condenser pipe, be inhaled into dedusting in deduster again, the condensed water of condensing tube condensation gained can flow into cesspool from the outlet at bottom of flue, in quenching tower, the water inlet of spray equipment is connected with cesspool, and the coke quenching water in quenching tower after quenching can flow in cesspool along the ditch of coke quenching cart bottom.
Further, the aforesaid flue gas scavenge unit for water quenching, wherein: collecting hood is in diminishing horn shape from bottom to top, and the import of flue is connected with the top of collecting hood.
Further, the aforesaid flue gas scavenge unit for water quenching, wherein: condenser pipe distributes in the shape of a spiral in flue.
Further, the aforesaid flue gas scavenge unit for water quenching, wherein: deduster is wet scrubber.
Advantage of the present invention is: the flue gas produced when the flue gas scavenge unit for water quenching of the present invention can remove water quenching, and it can make coke quenching water recycle, and greatly reduces the waste of water resource and the pollution to environment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the flue gas scavenge unit for water quenching of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention is described in further detail.
For the flue gas scavenge unit of water quenching, as shown in Figure 1, comprise support 1, support 1 is provided with the collecting hood 2 that can shelter from quenching tower 7 top exit, collecting hood 2 is in diminishing horn shape from bottom to top, collecting hood 2 is designed to horn-likely better to collect flue gas, support 1 is also provided with the flue 3 that import is connected with the top of collecting hood 2, the sidewall of flue 3 is connected with deduster 4, in actual applications, deduster 4 can use wet scrubber (such as: multi-pipe impact dust collector), wet scrubber manufacturing cost is relatively low, it not only can remove the dust in flue gas, cleaning solution also can be utilized to remove the peculiar smell in flue gas and be absorbed with harmful substances, for with moisture content, the flue gas of viscosity and penetrating odor is optimal dust arrester, blower fan in deduster 4 aspirates the flue gas in collecting hood into deduster 4 by flue 3, the condenser pipe carrying out steam in condensation flue gas by passing into condensate liquid is also provided with in flue 3, between deduster 4 access port of condenser pipe on collecting hood 2 and flue 3 sidewall, and condenser pipe distributes in the shape of a spiral in flue 3, condenser pipe distributes in the shape of a spiral can increase the contact area of condenser pipe and flue gas, the steam in flue gas is made more to be condensed into water, in actual applications, condensate liquid in condenser pipe can by after condensate circulation cooling device 5 rapidly cooling, in recirculation input condenser pipe, so just condensate liquid can be recycled, decrease the loss of condensate liquid, flue gas is first after the condensation of condenser pipe, be inhaled into dedusting in deduster 4 again, steam during such fume treatment order can farthest remove smoke and harmful substance, the condensed water of condensing tube condensation gained can flow into cesspool 6 from the outlet at bottom of flue 3, reuse again after the steam so just making water quenching produce can be condensed into water, save water resource, in quenching tower 7, the water inlet of spray equipment is connected with cesspool 6, spray equipment can extract water for quenching from cesspool 6, and the coke quenching water in quenching tower 7 after quenching can flow in cesspool 6 along the ditch of coke quenching cart 71 bottom, the coke quenching water stayed after quenching flows in cesspool 6 by ditch, and then for quenching, reuse coke quenching water like this and greatly can save water resource.
The operation principle of the flue gas scavenge unit for water quenching described in the present embodiment is: the spray equipment in quenching tower 7 can be collected cover 2 to the flue gas produced after the red-hot red burnt 72 spray coke quenching waters in coke quenching cart 71 and collect, blower fan rotation in deduster 4 can make to produce negative pressure in flue 3, the flue gas collected in collecting hood 2 can be inhaled in flue 3 because of negative pressure, first flue gas first removes wherein most steam through the condensation of condenser pipe, then flue gas is inhaled into dedusting in deduster 4 again, harmful substance remaining in flue gas is removed, gas after dedusting is discharged from the outlet of deduster 4.
Beneficial effect of the present invention is: the flue gas produced when the flue gas scavenge unit for water quenching of the present invention can remove water quenching, and it can make coke quenching water recycle, and greatly reduces the waste of water resource and the pollution to environment.
