Water mist fluid cold stripper, dehumidifying and demisting device and dehumidifying and demisting method thereof

Abstract

The invention discloses a water mist fluid cold stripper, a dehumidifying and demisting device and a dehumidifying and demisting method thereof. The stripper includes a hollow cold water jacket and acold water pipe, spiral flow guide plates are arranged between the cold water pipe and the inner wall of the hollow cold water jacket, a flow guide mechanism is arranged on the hollow cold water jacket, and the flow guide mechanism is used for guiding out water vapor fluid formed by condensation in water mist fluid, and the cold water pipe and the hollow cold water jacket are both connected to a cold water circulation mechanism. According to the invention, the water mist fluid cold stripper is equipped with the hollow cold water jacket, and the cold water pipe is disposed therein, also the spiral flow guide plates are arranged between the cold water pipe and the inner wall of the hollow cold water jacket, so that moisture and gas in water mist fluid not only can achieve condensation separation after flowing through the outer surface of the cold water pipe, the windward surfaces of the spiral flow guide plates and the inner surface of the hollow cold water jacket, but also can realize centrifugal separation in a spiral channel formed by the spiral flow guide plates, i.e. the cold stripper utilizes the mechanical centrifugal stripping mechanism and the cold wall heat transfer mechanism simultaneously, and ensures the stripping effect of fluid with high water vapor content.

Description

technical field [0001] The invention relates to the technical field of environmental protection and purification, in particular to a water mist fluid cold stripper, a dehumidification and demisting device and a dehumidification and demisting method thereof. Background technique [0002] At present, when dehumidifying and defogging fluids, there are usually the following seven technologies: [0003] 1. Compression dehumidification method: compress the air and then cool it, the water vapor in the air will condense into water, drain the condensed water and then heat it to obtain air with low humidity. Its characteristics are: 1) It is suitable for dehumidification with small air volume and low dew point; 2) The compression power cost is relatively large; 3) It is suitable for instruments, controls, etc. that need high-pressure and small amount of dehumidified air. [0004] 2. Solid-type adsorbent method: The surface of the adsorbent has a porous structure, and the moisture in ...
