Abstract
The invention relates to a heat exchange system capable of realizing waste gas recovery. The heat exchange system comprises a fan, a heat exchanger, a rotary separator, a cold water tower and a gas-liquid mixing tower and further comprises a first-stage purification mechanism, a second-stage purification mechanism and a third-stage purification mechanism; the third-stage purification mechanism controls opening and closing of an air inlet of the heat exchanger through a first transmission assembly and controls switching work of a liquid outlet a of the rotary separator through a second transmission assembly; a purification liquid storage tank is arranged outside the gas-liquid mixing tower, and a purification liquid in the purification liquid storage tank is continuously introduced into the first-stage purification mechanism; an output mechanism is arranged in the second-stage purification mechanism, and the output mechanism quantitatively and intermittently conveys the purification liquid into the third-stage purification mechanism; a separation mechanism is arranged below the third-stage purification mechanism. The technical problem that the waste gas purification effect is low due to the fact that products are fewer and fewer due to the fact that reactants of the purification liquid are fewer and fewer after the purification liquid of the gas-liquid mixing tower is subjected to multiple times of reactions is solved.
Description
technical field [0001] The invention relates to the technical field of waste gas recovery, in particular to a heat exchange system for waste gas recovery. Background technique [0002] At present, in my country's large and medium-sized cities, especially in economically developed areas, the amount of industrial waste gas has increased sharply, and the proper treatment of these waste gases has become more and more urgent. A large part of these waste gases are organic waste gases. There are many types of these organic waste gases. In the past, the method of direct discharge was used to deal with these organic waste gases. Contains gaseous organic solvents, direct discharge will cause serious pollution to the atmosphere, and is not conducive to the recycling of organic solvents. [0003] The patent document with the patent number CN2016101275320 discloses a waste gas recovery and heat exchange system, including a fan, a heat exchanger, a rotating separation chamber, a cooling ...
