Problems solved by technology

[0004] The object of the present invention is to provide a hydrogen chloride industrial waste gas condensation absorption recovery device, which first condenses the waste gas, so that the volume of hydrogen chloride at a higher temperature is greatly reduced, condensed and reduced to hydrochloric acid for recovery, so that the concentration of hydrogen chloride in the waste gas is greatly reduced After the volume is reduced, two-stage treatment is carried out through the absorption tower and the neutralization tower to alleviate the large consumption of chemicals and high operating costs of the existing treatment methods, and the high salt content in the water produced after neutralization will have an impact on the environment. Secondary pollution and other technical issues

Abstract

The invention provides a device and a system for condensing and absorbing recovery of hydrogen chloride industrial waste gas, and relates to the technical field of environmental protection. The condensing and absorbing device comprises a first condenser, the first condenser comprises a first shell, a plurality of first heat exchange tubes are arranged in the first shell, and a first atomization sprayer is arranged at the top of the first shell. The technical problems of large medicament consumption, high running cost and great influences of high salt of neutralizing water on the environment inexisting two-stage treatment using an absorbing tower and a neutralizing tower are alleviated. The device condensing and absorbing recovery of hydrogen chloride industrial waste gas makes the hydrogen chloride industrial waste gas rise in the heat exchange tubes and be condensed under the dual action of cooling water and the sprayer in order to make the hydrogen chloride condensed and reduced into hydrochloric acid, so efficiency increase and load reduction are achieved in the subsequent treatment using the absorbing tower and the neutralizing tower, thereby the medicament consumption is greatly reduced, the running cost is reduced, and adverse influences on the environment are avoided.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a hydrogen chloride industrial waste gas condensation absorption recovery device and system. Background technique [0002] Some chemical companies will emit waste gas containing a large amount of hydrogen chloride during the production process. If the waste gas is not treated, it will seriously pollute the environment. At present, the hydrogen chloride industrial waste gas is treated in two stages through the absorption tower and the neutralization tower, and then the waste gas that meets the standard is discharged into the atmosphere. However, due to the high content of hydrogen chloride in the waste gas and the high temperature, it is necessary to consume a large amount of water for hydrogen chloride absorption and a large amount of water. The acid-base neutralization of the lye results in a large consumption of chemicals and high operating costs, and the waste...
