Oil refining caldron with air preheating function of oil

Abstract

The invention discloses an oil refining caldron with an air preheating function of oil. The oil refining caldron comprises a blower of a gas furnace, the gas furnace and a caldron body, wherein a heat insulation outer cylinder is arranged on the periphery of the caldron body, a gas collection ring is arranged at the top of the heat insulation outer cylinder, high-temperature tail gas collected by the gas collection ring enters a sleeve type heat exchanger via a tail gas pipe by pumping by a rotor body, the sleeve type heat exchanger is connected with a combustion blower through a hot air pipe, the sleeve type heat exchanger is connected with a tube side above a tubular heat exchanger through a tail gas pipe, the tube side below the tubular heat exchanger is connected with a tail gas exhaust pipe, the lower part of a shell side of the tubular heat exchanger is connected with a cold storage oil tank, and the upper part of the shell side of the tubular heat exchanger is connected with a hot storage oil tank. The oil refining caldron disclosed by the invention can greatly improve the convection and heat conduction coefficient between gas flow and the wall surface by strengthening the disturbance of gas staying in a high-heat resistance layer to realize layer convection inside and outside the pipe, further reduce the temperature of the tail gas by forming counterflow heat exchange between gas flow and gas flow and between oil flow and gas flow, improve the heat recovery rate, realize energy conservation and synergy, and realize shorter oil refining time and higher work efficiency.

Description

technical field [0001] The invention belongs to the technical field of oil refining, and in particular relates to an air preheating oil refining pot. Background technique [0002] Oil and spicy seasoning products are an important part of Chinese food culture, and are loved by people because of their unique taste and convenience. This kind of food processing technology has the steps of refining ingredients oil, that is, cooking oil and auxiliary materials are refined, sterilized, matured, fused, and then added into mustard, fermented bean curd, spicy chicken, black bean pepper, etc. for preparation. This kind of food is favored by consumers and consumes a lot, so the energy consumption generated in the production process is also very large. At present, a large part of the traditional oil refining equipment for this type of food uses gas furnaces to generate gas, and then burns the gas to obtain heat sources, which still have the disadvantages of low thermal efficiency and hi...
