Description

Technical Field

[0001] The utility model relates to the technical field of condensation recovery, in particular to a condensation recovery device. Background Art

[0002] Condensation recovery is to cool the steam from the gas and condense it into liquid. It is suitable for recovering harmful substances in the vapor state; especially for recovering organic solvent vapor with a mass concentration of more than 1000mg / m3. In theory, it can achieve a very high degree of purification; but the cost also increases; the equipment and operating conditions required for condensation recovery are relatively simple, and the purity of the recovered material is relatively high. It is often used as a pre-treatment for purification methods such as adsorption and combustion to reduce the load when using these methods. For example, in the chlor-alkali industry, the condensation method is often used to convert mercury vapor into liquid mercury for recovery; in addition, the organic waste gas is also condensed by the condensation method to condense water vapor, which greatly reduces the amount of gas and is beneficial to the next step of operation; the water after condensation recovery is mostly warm water, and the recovered warm water can be used in many ways to reduce energy loss and be more energy-saving and environmentally friendly.

[0003] When the condensed and recovered water is transported to various devices, some devices require water of higher purity and need to filter out impurities in the water. It is necessary to add a filtering structure to the condensed water recovery tank. The existing filtering structure is not easy to disassemble for replacement or cleaning. For this reason, we propose a condensation recovery device. Utility Model Content

[0004] The main purpose of the utility model is to provide a condensation recovery device, which solves the problem that when the water after condensation recovery is transported to various equipment, some equipment requires water of higher purity, impurities in the water need to be filtered, and a filtering structure needs to be added to the condensation water recovery tank, and the existing filtering structure is not easy to disassemble, replace or clean.
