The invention discloses a chlorination tail gas absorption apparatus, which includes a buffer tank, a high concentration HCl absorption tank, a low concentration HCl absorption tank, a HCl residual gas adsorption tank, and a control box. By means of the modification, a problem of environment pollution in the prior art is solved. In addition, according to the embodiment, firstly the tail gas is purified by water spray, then with low concentration hydrochloric acid being a spray solution, not only is environmental problem solved but also value is created for enterprises. In addition, the apparatus has high tail gas absorption efficiency and is low in tail gas treatment cost, and can avoid tail gas pollution. The apparatus is convenient to use and has long service life; by means of the control box, the whole process is simple and the whole structure is compact. Compared with similar apparatuses, the apparatus is more energy-saving and environment-pollution.
Description
technical field [0001] The invention relates to the field of chlorination reaction tail gas treatment, in particular to an energy-saving and environment-friendly chlorination reaction tail gas absorption device. Background technique [0002] At present, in chemical production, the main sources of pollution are waste gas, waste water and waste residue. If they are not properly treated, if they are discharged into the environment without meeting the prescribed discharge standards, they will pollute the environment and are not environmentally friendly; for industrial waste gas Speaking of it, hydrogen chloride gas is a common waste gas, and the industrial treatment of hydrogen chloride often requires multiple towers for series absorption, which is time-consuming, laborious, inefficient, and not environmentally friendly. [0003] After analysis, it is found that these existing processing devices still have the following deficiencies when dealing with hydrogen chloride tail gas: ...
