Problems solved by technology

The biological filter has low operating cost and high treatment efficiency, but it occupies a large area and the operating conditions are not easy to control. Improper parameters will lead to a rapid increase in system pressure drop, resulting in excessive system energy consumption and performance degradation
Although the floor area of ​​the spraying biological scrubber is small, the gas-liquid contact area in the form of an empty tower is small, and the mass transfer effect is not good; the mass transfer effect in the form of a packed tower is greatly improved, but the overall investment of the device increases, and the circulating fluid improves the power The cost is high, and it is prone to blockage

Abstract

The present invention belongs to the field of environment protection technology, and is especially one kind of enhanced biological spraying and bubbling gas absorbing purifier. The purifier consists of an atomizing cooler, a spraying and bubbling wash unit, a dewatering unit, an overflow trough, a regeneration pond, etc. The spraying and bubbling wash unit consists of an upper tank, a bubbling pipe, a lower tank and a liquid biological medium layer. Inside the lower tank, there are liquid biological medium layer, stirring pipeline in the bottom and bubbling pipe inserted into the liquid biological medium layer. The present invention has simple structure, reasonably designed pipeline, and easy maintenance.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection, and specifically relates to an enhanced spray bubbling gas biological absorption purification device. Background technique [0002] Due to the rapid development of modern industry, waste gas containing various pollutants discharged in the industrial process has caused serious pollution to the atmospheric environment. In order to protect the environment, more and more attention has been paid to the purification of exhaust pollutants. The current treatment methods for exhaust pollutants basically use physical, chemical and biological means, or a combination of these methods. It is generally believed that physical and chemical methods have the disadvantages of high energy consumption, large investment, and secondary pollution. Therefore, in recent years, the development and application of biological control technology for waste gas has increased. [0003] Biotechnology uses the degradati...
