Description

Technical Field

[0001] The utility model relates to the technical field of incineration equipment, in particular to a device for recovering and utilizing waste heat from incineration of high-halogen hazardous waste. Background Art

[0002] With the development of science and technology, the methods for treating hazardous wastes are gradually increasing. Industrial hazardous wastes with high content of salt, chlorine, fluorine, bromine and other halogens are one of the many wastes. In order to avoid pollution to the surrounding environment, they need to be purified by incineration.

[0003] In the prior art, a Chinese patent with announcement number CN215833103U discloses an AOX halogen combustion furnace protection device that is convenient for temperature detection. The device adopts a scheme of "including an equipment body, a lower incineration equipment shell is fixedly installed on the top of the equipment body, and a second telescopic shell is fixedly installed on the side of the lower incineration equipment shell". The scheme is provided with a connecting gear, a first telescopic block, a linkage rod and an auxiliary telescopic rod. The connecting gear on the side of the connecting rod is controlled by a connecting handle to rotate on the surface of the fixed round block. During the rotation, the first telescopic block is controlled to be lifted and lowered by the meshing tooth grooves. During the lifting and lowering process, the linkage rod drives the second telescopic block to be lifted and lowered together, so that the upper incineration equipment shell is lifted and lowered smoothly. At the same time, the auxiliary telescopic rod on the side of the upper incineration equipment shell is lifted and lowered in the first telescopic shell of the lower incineration equipment shell, so that contactless opening can be achieved to avoid burns.

[0004] However, the above scheme still has some shortcomings. For example, when the above scheme is actually used, it lacks a mechanism for preheating the incineration material by utilizing the waste heat of the flue gas, which causes waste heat. When the cold halogen waste enters the incineration equipment, it will reduce the overall temperature inside, thereby affecting the subsequent incineration efficiency and effect. At the same time, when the incineration equipment shell is opened, the harmful gas in the incineration shell will leak and be exposed to the air, causing pollution to the surrounding environment. There is a lack of a mechanism to prevent gas leakage. In view of this, the utility model proposes a high-halogen hazardous waste incineration waste heat recovery and utilization device.
