Heat pipe heat-transfer type gas-liquid-solid three-phase circulation flow reactor

Abstract

The invention discloses a heat pipe heat-transfer type gas-liquid-solid three-phase circulation flow reactor which comprises a three-phase circulation flow reactor body and a heat transfer device, wherein the three-phase circulation flow reactor body comprises a tower body, an upper seal head, a lower seal head and a lifting pipe; the upper seal head, the lower seal head and the lifting pipe are matched with the tower body; an annular space area is formed in the tower body; the heat transfer device is a heat pipe; the heated end of the heat pipe is arranged in the annular space area; the heat release end of the heat pipe is arranged outside the tower body; a cooling medium is arranged around the heat release end of the heat pipe. After heat is absorbed from the heated end of the heat pipe, the heat is transferred to the heat release end of the heat pipe outside the tower body and is taken by the cooling medium through phase change and flow of the working medium in the heat pipe, so that heat in a bed is removed. According to the reactor, the high-efficiency heat transfer can be realized, and the operation, the regulation and the maintenance in the later stage are convenient.

Description

technical field [0001] The invention belongs to the fields of energy engineering and chemical engineering, in particular to a gas-liquid-solid three-phase spray circulation reactor of a composite heat pipe. Background technique [0002] The three-phase spouted circulating bed is a gas-liquid-solid reactor with good application prospects. Its working principle is that the gas phase or liquid phase or the gas-liquid two-phase mixture is sprayed into the reactor at a relatively high speed to form a jet. Under the action of jet propulsion and static pressure difference propulsion, the fluid inside the reactor forms an up-and-down circulation flow, and at the same time drives the circulation of solid phase particles. Compared with the conventional three-phase circulating fluidized bed, the movement of solid phase particles has better order, which has a good advantage in the occasions where solid phase renewal needs to be considered, and is expected to be applied in petrochemical,...
