Double helix water stream barrel type high-efficiency coolers

Abstract

The invention relates to a double helix water flow cylinder type efficient cooler which comprises a cylinder body, an internal sleeve and a helix pipe and is characterized in that the interior of the cylinder body is provided with a rotational flow generating device, and the rotational flow generating device is composed of an outer diversion sleeve, an inner diversion sleeve, a ring-shaped partition plate and a sealing plate; an outer ring guide space is formed between the outer diversion sleeve and the cylinder body wall, and the outer ring guide space is corresponding with the outer side space of the helix pipe; an inner ring guide space is formed between the inner diversion sleeve and the outer diversion sleeve, and the inner ring guide space is corresponding with the inner side space of the helix pipe; the walls of the outer diversion sleeve and the inner diversion sleeve is uniformly distributed with a diversion hole, and the diversion hole is arranged in the vortex direction of that the center extension line of the circumferential direction doesn't pass through the shaft center; the outer diversion sleeve and the bottom of the inner diversion sleeve form a water inlet chamber, and one end of the water inlet chamber is communicated with a cooling water inlet pipe and the other end of the water inlet chamber is communicated with the inner and outer ring guide space through each diversion hole. The cooling water of the invention can be divided into the inner and outer streams which spirally upwards flow in order to result in that the inner and outer sides of the helix pipe are uniformly cooled, which thereby finally improves the efficiency of heat exchange.

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...
