Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon production, in particular to a pipeline heater for activated carbon production. Background Art

[0002] Activated carbon is a specially treated carbon. The organic raw materials are heated in an airtight condition to reduce the non-carbon components, and then react with the gas to erode the surface and produce a well-developed microporous structure. Activated carbon is prepared by pyrolysis and activation of carbon-containing raw materials such as wood, coal and petroleum coke.

[0003] At present, in the activated carbon production process, a pipe heater is used to heat the liquid added to the activated carbon raw material, but the existing pipe heater does not have a reflux structure, and the liquid flowing out of the pipe heater that does not reach the predetermined heating temperature cannot flow back for reheating. Therefore, a pipe heater for activated carbon production is proposed. A reflux device is installed on the pipe heater, so that the liquid flowing out of the pipe heater that does not reach the predetermined heating temperature can flow back into the pipe heater for heating. Utility Model Content

[0006] A reflux assembly is arranged outside the tank body, and the reflux assembly comprises a reflux pipe arranged outside the tank body, one end of the reflux pipe is connected to a booster pump through a pipeline joint, and a feed end of the booster pump is connected to a valve through a pipeline.

[0007] By adopting the above technical solution, the liquid flows into the inner cylinder and is heated by the heating pipe. The liquid that flows out of the inner cylinder and does not reach the predetermined temperature can flow back into the inner cylinder through the reflux pipe and be heated again.

[0008] Specifically, a feed pipe is welded on the top of the tank body, a discharge pipe is welded on the bottom of the tank body, one end of the reflux pipe is connected to one side of the feed pipe through a pipe joint, and one end of the valve is connected to one side of the discharge pipe through a pipe.

[0009] Specifically, a heat-insulating layer is provided between the tank body and the inner tube, and the heat-insulating layer is made of polyvinyl chloride material.

[0010] Specifically, a temperature controller is installed at one end of the tank body through a mounting seat, a detection end of the temperature controller is located inside the inner tube, and a current output end of the temperature controller is electrically connected to a current input end of the heating pipe through a power line.

[0011] Specifically, a one-way valve is sleeved on the outer side of the reflux pipe close to the feed pipe, and support frames are fixed to both ends of the bottom of the tank body by bolts.

[0012] Specifically, a discharge valve is connected to the bottom of the discharge pipe through a threaded groove, a temperature gauge is installed on one side of the discharge pipe through a mounting frame, and a detection end of the temperature gauge is located inside the discharge pipe.
