Air bathing type gasifier easy to deice

Abstract

The invention discloses an air bathing type gasifier easy to deice. The inlet ends of a plurality of heat exchange pipes are connected with a liquid inlet pipe after being connected in series, the outlet ends are connected with an air discharge pipe after being connected in series, a cross-shaped insert piece is arranged in each heat exchange pipe, fins are vertically and uniformly connected with the outer walls of the heat exchange pipes, wherein the heat exchange pipes are snake-shaped, the longitudinal gaps between the parallel sections shrink gradually along the liquid medium flow direction, and the fin number is increased gradually section by section; each cross-shaped insert piece is spiral so as to enable the liquid low-temperature medium to generate an obvious dispersion flow effect in the heat exchange pipe. According to the air bathing type gasifier easy to deice, the environment temperature at four sides of the air bathing type gasifier easy to deice descends slowly through expanding the longitudinal gaps between parallel sections of the heat exchange pipes near the inlet end and reducing the fin number at the inlet end, so that the air bathing type gasifier is not easy to deice; the air bathing type gasifier easy to deice has beneficial effects of simple structure, convenience in use, high heat exchange efficiency, low cost and the like, and the air bathing type gasifier easy to deice can be broadly used for different large, medium and small enterprises and public institutions.

Description

technical field [0001] The invention relates to an air-bath gasifier, in particular to an air-bath gasifier which is easy to remove ice. Background technique [0002] In the existing technical field, the air bath gasifier is generally mainly composed of heat exchange tubes and fins. The parallel sections of the heat exchange tubes are equally spaced, and the fins are also equally installed on the heat exchange tubes. The number of fins is generally 12 pieces. Because the liquid low-temperature medium absorbs a large amount of heat in the atmosphere near the inlet of the heat exchange tube, the moisture in the atmosphere condenses into a thick ice layer on the surface of the inlet tube, which seriously affects the effect of heating and gasification. The internal surface area of ​​the heat pipe is small, and the ratio of the surface area of ​​the heat pipe to the fin surface cannot be between 1:7 or 1:10. The simple flow of the liquid low-temperature medium in the pipe cannot ...

The internal surface area of ​​the heat pipe is small, and the ratio of the surface area of ​​the heat pipe to the fin surface cannot be 1:7 or 1:10. The simple flow of the liquid low-temperature medium in the pipe cannot perform sufficient heat exchange, and it is easy to generate dirt, which seriously affects the Heat transfer efficiency
