Technical Field
[0001] The utility model relates to the technical field of incinerators, and particularly relates to a sealed slag discharging device for molten salt of an incinerator. Background Technique
[0002] An incinerator is an environmental protection device that incinerates waste gas, waste liquid, solid waste, such as toxic gases (spray painting tail gas), toxic rocket liquid fuel, medical waste, domestic waste, animal carcasses, etc. at high temperature to achieve a reduction or shrinkage in quantity, and at the same time, it is a product that utilizes the heat energy of part of the incineration medium.
[0003] Incinerators are divided into fixed incinerators and mobile incinerators. When an incinerator is in use, a slag discharging operation needs to be carried out. However, the slag discharging port of the existing incinerator has a simple structure, and the phenomenon of blockage occurs when discharging slag, and it cannot be processed. Since the slag discharging port of the incinerator is in an open state, there are potential safety hazards.
[0004] Therefore, we propose a sealed slag discharging device for molten salt of an incinerator. Content of the Utility Model
[0005] The main purpose of the utility model is to provide a sealed slag discharging device for molten salt of an incinerator. The molten salt enters the first slag discharging channel in the slag discharging pipe through the high-temperature molten salt discharging port, and then enters the second slag discharging channel through the pipeline to achieve the purpose of slag discharging. Through the design of the burner, the blockage of the molten salt in the adiabatic laminar flow channel can be avoided, and the problems in the background technique can be effectively solved.
[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0007] A sealed slag discharging device for molten salt of an incinerator includes a sealed metal shell, an adiabatic laminar flow channel, a burner, an observation sight glass, and a detection instrument interface. The sealed metal shell is a horizontally arranged cylindrical structure. The adiabatic laminar flow channel is located inside the sealed metal shell. One end of the sealed metal shell is connected to one side of the bottom of the incinerator body. The adiabatic laminar flow channel is communicated with the inside of the incinerator body. A slag discharging pipe is provided at the lower part of the end of the sealed metal shell away from the incinerator body. The bottom end of the slag discharging pipe is connected to a pipeline;
[0008] The burner is installed at the top of the sealed metal shell. Observation sight glasses and detection instrument interfaces are respectively provided on both sides of the burner at the top of the sealed metal shell. A coke cleaning port is provided at the end of the sealed metal shell away from the incinerator body. A high-temperature molten salt inlet is provided at the end of the sealed metal shell away from the coke cleaning port. A high-temperature molten salt discharging port is provided at the bottom end of the sealed metal shell at the position where the slag discharging pipe is located.
[0009] By adopting the above technical solution, the molten salt enters the adiabatic laminar flow channel located inside the sealed metal shell through the high-temperature molten salt inlet, enters the first slag discharge channel inside the slag discharge pipe through the high-temperature molten salt discharge port, and then enters the second slag discharge channel through the pipeline to achieve the purpose of slag discharge.
[0010] Specifically, the adiabatic laminar flow channel is respectively communicated with the coke cleaning port, the high-temperature molten salt discharge port and the high-temperature molten salt inlet.
[0011] Specifically, there are two groups of the observation sight glasses, and the other group of the observation sight glasses is arranged at one end of the sealed metal shell far away from the incinerator body.

At the same time, the cooperation of the above structures enables the incinerator body and the sealed slag discharge device to form a sealed body to achieve the purpose of sealing, and further improves its safety;
[0016] The molten salt enters the adiabatic laminar flow channel located inside the sealed metal shell through the high-temperature molten salt inlet, enters the first slag discharge channel inside the slag discharge pipe through the high-temperature molten salt discharge port, and then enters the second slag discharge channel through the pipeline to achieve the purpose of slag discharge;
