Double helix water stream barrel type high-efficiency coolers

Abstract

A double-helix water flow cylinder type high-efficiency cooler, including a cylinder body, an inner sleeve, and a spiral tube, is characterized in that: a swirl flow generating device is provided at the bottom of the cylinder body, and the swirl flow generating device is composed of an outer flow guide sleeve and an inner flow guide sleeve , an annular partition and a sealing plate; an outer ring guide space is formed between the outer diversion sleeve and the cylinder wall, and the outer ring guide space corresponds to the outer space of the spiral tube; an inner ring guide space is formed between the inner guide sleeve and the outer guide sleeve , the guiding space of the inner ring corresponds to the inner space of the helical tube; the first and second guiding holes are evenly distributed on the wall surfaces of the outer guiding sleeve and the inner guiding sleeve, and the vortex that their central extension lines do not pass through the axial center in the circumferential direction The direction of rotation is set; the bottom of the inner cavity of the outer diversion sleeve and the inner diversion sleeve forms a water inlet chamber, one end of which is connected to the cooling water inlet pipe, and the other end is guided to the space by the first and second diversion holes and the inner ring , The outer ring guides the spatial connection. The cooling water of the present invention can be divided into two helical strands, inner and outer, to flow upwards, so that the inner and outer sides of the helical tube can be cooled uniformly, thereby finally improving the heat exchange efficiency.

Description

technical field [0001] The invention belongs to mechanical engineering heat exchange equipment without direct contact with the heat exchange medium, and in particular relates to a cylinder cooling device used for an online sampling and analysis device for high-temperature water and steam in a thermal power plant thermal system. Background technique [0002] In the thermal system of thermal power generation, the quality of the working medium—high temperature and high pressure water and steam directly affects the safety performance of the heat engine. Therefore, online continuous analysis and monitoring of high temperature and high pressure water and steam sampling is indispensable. If it is unrealistic to directly introduce high-temperature and high-pressure water and steam into online instruments, it is usually necessary to reduce the temperature, pressure, and flow of water and steam to the conditions allowed by the normal operation of the analysis and monitoring instrument...
