Abstract

The invention relates to cooling equipment, and discloses a double-effect cooler. The double-effect cooler comprises an outer barrel with a closed end and an open end, wherein an outer barrel flange is arranged on the outer rim of the open end; an end cover flange is fixed on the outer barrel flange through a bolt; a cooling water inlet is formed on the wall of the outer barrel; a cooling water outlet, a sample water outlet and a sample water inlet are formed on the end cover flange; the sample water outlet and the sample water inlet are respectively connected to the two ends of a dual-helix coil pipe; an inner barrel is arranged inside the outer barrel; the dual-helix coil pipe is divided into an outer coil pipe and an inner coil pipe; the inner coil pipe is inserted into the inner barrel; the outer coil pipe is sleeved on the outer side of the inner barrel; the inner coil pipe is connected with the sample water inlet at the end cover flange; the outer coil pipe is connected with the sample water outlet at the end cover flange; and the cooling water outlet is in the range of the inner barrel at the end cover flange. Compared with the conventional single-helix-coil-pipe cooler, the double-effect cooler has the advantages of increasing the heat exchange area, saving the material cost, prolonging the heat exchange time, improving the heat exchange efficiency and reducing the running cost.

Description

technical field [0001] The invention relates to cooling equipment, in particular to a double-effect cooler in a water vapor centralized sampling and analysis device. Background technique [0002] The centralized water vapor sampling and analysis device is a device suitable for centralized water vapor sampling and analysis in steam power plants and steam supply equipment. Its main function is to cool down, depressurize, and constant temperature the high-temperature and high-pressure water vapor samples, and then detect and analyze them with online instruments. . [0003] With the advancement of science and technology, in order to meet the needs of low-carbon environmental protection and sustainable development, steam-powered power plant boilers have gradually shifted from high-pressure boilers to subcritical pressure boilers and supercritical pressure boilers. The pressure and temperature of steam-water samples have also changed from 6-14MPa, 46 -540°C is increased to 17-22M...
