Embodiment Construction

[0021] The device for purifying volatile organic compound gas with liquid-gas medium of the present invention first impacts the non-acid and non-alkaline harmful gas into the liquid through the air inlet (1) under the effect of negative pressure, and the larger particles in the gas are Under the action of gravity and gravity, it rushes into the liquid and sinks to the bottom of the pool. Smaller particles and gases form a gas-liquid mixture and hit the screen upward. When a large amount of harmful gas-liquid mixture rushes through the screen, harmful gases will accumulate. After the liquid is produced, the harmful liquid will flow into the other end under the screen through one end of the circulation pipe (5), and the circulation pipe (5) will play a circulating role, and the gas other than the harmful liquid will enter the middle VOC volatile gas At the same time, it is also necessary to add nitrogen oxides and VOC volatile gases in the photochemical reaction chamber through t...

Abstract

The invention discloses an apparatus for purifying volatile organic gas by liquid and gas media, and belongs to the field of gas purification. Firstly, gas to be purified is driven to impact liquid under action of pressure, particles in the gas are captured and absorbed after contacting with the liquid, and the volatile organic gas which cannot be removed enters a VOC (volatile organic compound) reaction chamber; and a certain quantity of nitrogen oxide is added to be subjected to intense photochemical reaction with the volatile organic gas under optical waves generated by an ultraviolet lamp and high-pressure mercury, so that the volatile organic gas is removed. By the apparatus, the problem that the volatile organic gas which is a VOC cannot be dissolved in acid or alkali and accordingly cannot be removed by the acid or alkali is solved, and the volatile organic gas can be purified by double action of the liquid-phase and gas-phase media.

Description

technical field [0001] The invention relates to a device for purifying volatile organic compound gas with a liquid-gas medium, in particular to a device for purifying gas with a liquid-phase medium capable of removing non-acid and non-alkali volatile VOC harmful gases. Background technique [0002] VOC volatile organic compounds can destroy the ozone layer and produce photochemical smog. It is also one of the causes of allergies (congenital allergies) and building syndrome that have attracted much attention in recent years. It has long been pointed out that it is harmful to the earth's environment and Effects on the human body. [0003] The generation of VOC mainly has two aspects: industry and people's livelihood. In terms of industry, the increase in the output of various products has led to the deterioration of the operating environment. VOCs in the industry are mostly produced in petroleum, adhesives, paints, dry cleaning, printing, chemicals, surface cleaning and other...
