Description

Technical Field

[0001] The utility model relates to the field of smoke recovery devices, in particular to a smoke recovery device for coal tar production. Background Art

[0002] A coke oven is a furnace used to refine coke. A modern coke oven consists of a carbonization chamber, a combustion chamber, a heat storage chamber, a ramp area, a furnace top, a foundation, a flue, etc. The coal in the carbonization chamber is heated to become coke under air-isolated conditions. The coke oven will produce high-temperature flue gas during operation. If the high-temperature flue gas is directly transmitted to the flue gas purification device, it will cause heat waste. Therefore, it is necessary to recover the heat in the flue gas to improve the heat utilization rate.

[0003] A Chinese patent document with publication number CN219252015U discloses a coke oven flue gas recovery device, which comprises an outer shell with an insulation layer inside to prevent the internal temperature of the device from being lost to the surrounding area and causing uncontrollable factors. The device also comprises an inner shell with a cavity inside. Normal temperature water is passed into the cavity to absorb the high temperature in the flue gas. A water pipe is opened through a switch valve on one side to allow water to flow. When the normal temperature water reaches a certain temperature, the switch valve on the other side is opened and the water is discharged to a designated position through the water pipe to form heat recovery.

[0004] When the device adopts the method of introducing room temperature water to absorb the high temperature in the flue gas, this method has the advantage of fast heating, but the disadvantages of this method are also obvious: the flue gas flows too fast inside the heating furnace, resulting in a shorter contact time between the room temperature water and the flue gas, resulting in low heat utilization rate, which in turn causes waste problems.

[0030] refer to Figure 1-Figure 5 , when using,

[0031] Place the furnace body 3 horizontally on the ground so that the equipment is supported, and assemble the filter frame 5 into the interior of the furnace body 3, and then use bolts to fix the furnace cover 1 to the top of the furnace body 3, so that the furnace body 3 and the furnace cover 1 cooperate with each other to form a heat-generating furnace;
