Problems solved by technology

[0002] At present, with the continuous acceleration of industrialization, environmental problems are becoming more and more prominent. The emission of greenhouse gases, dust, and harmful gases has received widespread attention around the world. The best is to use bag dust removal and electrostatic dust removal. These two methods generally can only remove larger dust particles, but are helpless for smaller dust and carbon dioxide. Moreover, the aforementioned two dust removal methods require more sophisticated equipment. The cost is relatively high, so many manufacturers still discharge industrial waste gas directly into the atmosphere due to the cost of dust removal

Embodiment Construction

[0009] Below by accompanying drawing and embodiment this industrial waste gas discharge method is further explained:

[0010] In the embodiment shown in the accompanying drawings, the equipment used in the method includes: an air pump 2, an exhaust gas pipeline 3, a mesh plate 4, and a well. The method is implemented as follows: dig a well 5 near the exhaust gas discharge source 1, accumulate water in the well, and put Lime water is poured into the well to maintain a suitable CaOH concentration, and a multi-layer stencil 4 is installed in the well. The mesh of each stencil 4 is small enough, and the exhaust gas generated by the exhaust gas discharge source is introduced into the bottom of the well by the air pump 2 through the exhaust gas pipeline 3 , so that the carbon dioxide in the exhaust gas is absorbed by the lime water in the well, and the large air bubbles are divided at the 4 meshes of the mesh plate, so that the dust in the gas is dissolved into the water when the air...

Abstract

The invention provides an industrial waste gas emission method, which is characterized in that a well with water accumulated is dug up near a waste gas emission source and then added with lime water, proper CaOH concentration is maintained, multiple layers of meshed plates are arranged in the well with meshes of each being small enough, the waste gas from the waste gas emission source is guided to the bottom of the well by a gas pump through a waste gas pipeline so that carbon dioxide in the waste gas is absorbed by the lime water in the well and large bubbles are divided at the meshes of the meshed plates, thus dusts and impurities in the gas are dissolved in the water when the bubbles break up. The industrial waste gas emission method has simple flow and equipment adopted, low dust removal cost and good effect.

Description

Technical field [0001] The invention relates to the field of environmental protection, in particular to a method for discharging industrial waste gas. Background technique [0002] At present, with the continuous acceleration of industrialization, environmental problems are becoming more and more prominent. The emission of greenhouse gases, dust, and harmful gases has received widespread attention around the world. The best is to use bag dust removal and electrostatic dust removal. These two methods generally can only remove larger dust particles, but are helpless for smaller dust and carbon dioxide. Moreover, the aforementioned two dust removal methods require more sophisticated equipment. The cost is relatively high, so many manufacturers still discharge industrial waste gas directly into the atmosphere due to the cost of dust removal. Contents of the invention [0003] For the problems referred to above, the object of the present invention is to provide a method for di...
