Problems solved by technology

Traditional waste gas treatment technology can no longer meet the needs of various toxic and harmful organic gases. At the same time, all localities have put forward zero emission requirements for enterprises. Traditional combustion methods and adsorption methods will produce secondary emissions or solid waste. Therefore, Physical treatment and recovery of industrial waste gas to realize resource reuse will be an inevitable choice for industrial enterprises

Abstract

The invention provides a low-temperature waste gas treatment and recovery system and method. The system comprises a generation section which is connected to a heating coil pipe, wherein the heating coil pipe is connected to a low-temperature heat pump auxiliary radiator; and a purification section which is connected to a combined condenser, wherein the combined condenser is connected to the low-temperature heat pump secondary refrigerant circulating pipeline pump; steam generated by the generation section serves as an inlet of gas of the purification section, and high-purity gas purified by the purification section enters the condensation section to be condensed and then enters the liquid storage tank. The secondary refrigerant can be used as a refrigeration medium to realize condensationand liquefaction of industrial waste gas under a low temperature condition; the system operates under negative pressure and is suitable for toxic and high-concentration industrial waste gas which is not easy to combust and adsorb, greatly reduces the energy consumption of conventional waste gas treatment by driving energy input through the low-temperature heat pump, realizes recovery of productionraw materials after waste gas purification, and saves the production cost and the raw material consumption.

Description

technical field [0001] The invention relates to the field of industrial waste gas treatment, in particular to a low-temperature waste gas treatment and recovery system and method. Background technique [0002] As my country's environmental protection requirements are increasing year by year, the requirements for waste gas treatment in the industrial field are becoming increasingly stringent. Traditional waste gas treatment technology can no longer meet the needs of various toxic and harmful organic gases. At the same time, all localities have put forward zero emission requirements for enterprises. Traditional combustion methods and adsorption methods will produce secondary emissions or solid waste. Therefore, It is an inevitable choice for industrial enterprises to physically process and recycle industrial waste gas to realize resource reuse. In view of the current actual demand for the treatment and reuse of high-concentration and toxic waste gas in the industrial waste ga...
