Separation and recovery device for low pressure and high air volume condensation water containing steam

Abstract

The invention discloses a separation and recovery device for low pressure and high air volume condensation water containing steam. The separation and recovery device is characterized by comprising a casing; a mist inlet, a drainage opening and a dry air exhaust outlet are formed in the casing; the mist inlet is communicated with an original air duct mist outlet; the drainage opening is communicated with a drainage main pipe; a water collection tank is arranged at the bottom inside the casing; an overflow water opening for limiting the water level and formed in the water collection tank is communicated with the drainage main pipe; calandria water condensers are arranged in the casing and located above the mist inlet; baffling mist eliminators are arranged above the calandria water condensers. The calandria water condensers are formed by one or more calandria pipes transversely arranged in the casing. The baffling mist eliminators are formed by one or more rows of baffling plates longitudinally arranged in the casing. The area of the dry air exhaust outlet is less than the cross-sectional area of the casing and is greater than the area of the mist inlet. The separation and recovery device can effectively solve the problem of steel companies, namely low-pressure and high air volume contained steam and the condensation water are directly discharged into the atmosphere, as a result, the separation of water and mist and the recovery and utilization are realized.

Description

technical field [0001] The invention relates to a separation and recovery device for steam condensed water carried by low pressure and large air volume. technical background [0002] In the process of cold rolling and continuous casting press plate in steelmaking enterprises, water and wind are mixed for cooling. The mixing of water and wind will generate a large amount of water vapor, and a large amount of water vapor will generate a large amount of condensed water when it encounters cold air. The existing technology is The steam condensate carried by the low pressure and large air volume is directly discharged into the atmosphere through the outlet, which not only causes a lot of water waste but also causes steam pollution, especially in winter in the northern region, the condensate falls everywhere in the factory area, and when it falls to the top of the factory building, it condenses hugely. Ice cubes will increase the pressure on the top of the factory building, which w...
