Tail heat recycling rendering kettle

Abstract

The invention discloses a tail heat recycling rendering kettle which comprises a gas stove air blower, a gas stove and a kettle body, wherein the gas stove air blower is connected with the gas stove; the gas stove is connected with a coal gas combustor through a coal gas tube; a coal gas control valve for controlling in / out of the coal gas is arranged on the coal gas tube; the kettle body is arranged above the coal gas combustor; an outer thermal-insulating cylinder is arranged at the periphery of the kettle body; a gas collecting ring is arranged on the top of the outer thermal-insulating cylinder; high-temperature tail gas collected by the gas collecting ring is sucked and fed into a casing type heat exchanger by a tail gas pipe through a rotor body; the rotor body is driven by a motor to rotate; the casing type heat exchanger is connected with the air inlet of the combustion air blower through an over-hot air tube; the air outlet of the combustion air blower is connected with the coal gas tube through a pipeline. By adopting the tail heat recycling rendering kettle, a retained high-heat barrier gas can be disturbed, and meanwhile the convective heat-transfer coefficient of air flow and a wall surface is greatly increased due to convective flow of the inner and outer layers of the tube; tail heat generated in the oil refining process can be efficiently recycled, the utilization rate of energy is increased, and the purposes of energy conservation and effect improvement can be achieved.

Description

technical field [0001] The invention belongs to the technical field of oil refining, and in particular relates to a tail heat recovery oil refining pan. 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...
