Detailed Description
The utility model is shown in figures 1-2 and comprises a waste gas fort 13, wherein the waste gas fort 13 is vertically arranged, the top of the waste gas fort 13 is communicated with a waste gas discharge mechanism, and one side of the waste gas fort 13 is provided with a furnace body 22 through hole for accommodating a calcining furnace, so that the feed end of the furnace body 22 is positioned in the waste gas fort 13;
the lower part of the inner wall of the waste gas barrel stand 13 is fixedly connected with a primary deposition hopper 131, the primary deposition hopper 131 is in an inverted circular truncated cone shape and is located below the furnace body 22, a primary deposition discharge hole is formed in the bottom of the primary deposition hopper 131, a first valve 132 is arranged in the primary deposition discharge hole, and a discharge door 133 is formed in the bottom of the waste gas barrel stand 13 (so that an operator can conveniently and efficiently collect and move out zinc oxide deposited for the first time through a trolley). Like this, the air current that gets into in the waste gas fort from the furnace body will be in the waste gas fort primary cooling for most zinc oxide falls naturally under the dead weight influence in the air current, and the concentrated collection is on a deposit fill, and operating personnel can open a valve one at an interval, carries out convenient recovery to the zinc oxide of collecting.
The exhaust gas discharge mechanism 14 includes a communicating pipe 141, a secondary deposition pipe 142 and an outlet pipe 143, the communicating pipe 141 is horizontally arranged, one end of the communicating pipe 141 is fixedly connected to the top of the outer wall of the waste gas fort 13 and is communicated with the waste gas fort 13, the secondary deposition pipe 142 is vertically arranged, the top end of the secondary deposition pipe 142 is butted with one end of the communicating pipe 141 far away from the waste gas gun platform 13, the bottom of the secondary deposition pipe 142 is provided with a secondary deposition discharge hole, a second valve 144 is arranged in the secondary deposition discharge hole, the gas outlet pipe 143 is horizontally disposed and one end thereof is communicated with the lower portion of the secondary deposition pipe 142, one end of the gas outlet pipe 143, which is far away from the secondary deposition pipe 142, is connected with a blower 145 (the blower only needs to pass through a low rotating speed, so that the gas in the communicating pipe, the secondary deposition pipe and the gas outlet pipe has a certain flow speed, but not keeps still). Like this, the gas that flows out from the waste gas fort will get into the secondary deposit pipe behind communicating pipe to further cool off in the secondary deposit pipe, make wherein the very little zinc oxide that carries finally fall to secondary deposit discharge gate in collect, thereby stopped and finally contained the problem of zinc oxide in the gas that flows out from the outlet duct. Similarly, an operator can open the second valve at intervals to conveniently recover the collected zinc oxide.
Therefore, through the processes of primary deposition and secondary deposition, the discharged tail gas is cooled, and the zinc oxide in the tail gas is recovered, so that on one hand, the influence on the surrounding environment of a production workshop is reduced, and the pollution to the environment is avoided; on the other hand, a small amount of zinc oxide contained in the tail gas is cooled and recovered, so that the waste of raw materials is avoided.
Waste gas is got rid of the mechanism and is still included the air-cooled mechanism, the air-cooled mechanism includes booster fan 151, cooling tuber pipe 152 and cooling tuber pipe two 153, booster fan 151 fixed connection is in the top of air-blower 145, cooling tuber pipe 152 is the spiral and changes the winding outside secondary sedimentation pipe 142, cooling tuber pipe two 153 is the heliciform winding outside waste gas fort 13, booster fan 151, cooling tuber pipe 152 and cooling tuber pipe two 153 communicate in proper order. Therefore, air outside the workshop exchanges heat with the secondary deposition pipe firstly and then exchanges heat with the waste gas gun platform, and on one hand, the two positions can be cooled respectively, so that zinc oxide can be deposited better and faster; on the other hand, the air temperature in the cooling air pipe II can be higher than that in the cooling air pipe I, so that the problems of cracking of the waste gas gun platform and the like caused by excessive cooling are avoided through preheating of the cooling air pipe I, and the actual service lives of the air cooling mechanism and the waste gas gun platform are prolonged.
