Abstract
The invention discloses a waste gas filter material for a straw incinerator. The waste gas filter material sequentially comprises a three-dimensional reticular structure, a first non-woven material layer, a second non-woven material layer, a woven fabric and a coating from bottom to top, wherein the first non-woven material layer is made from metal fibers; the second non-woven material layer is made from bast fibers; a film layer is arranged between the first non-woven material layer and the second non-woven material layer and / or between the second non-woven material layer and the woven fabric and / or between the woven fabric and the coating; the apertures of the layers of the waste gas filter material are sequentially reduced from bottom to top, and the waste gas filter material forms a spiral shape in appearance. The invention also discloses a production method for producing the straw incineration waste gas filter material. The production method comprises the following steps: adhering the structures of the layers together by utilizing a hot rolling method; carrying out sanding treatment on the lower surface of the three-dimensional reticular structure. By adopting the mode, the waste gas filter material disclosed by the invention can be used for decreasing the harmful substances, namely sulfur dioxide, nitrogen dioxide, inhalable particles and the like which are generated by straw incineration, thereby protecting the earth environment and the physical health of human.
Description
technical field [0001] The invention relates to the field of new filter materials, in particular to a waste gas filter material for straw incinerators and a manufacturing method thereof. Background technique [0002] Today, with the rapid economic and social development, energy and ecological issues have attracted more and more attention. Without energy, economic development will lose momentum; with ecological damage, people's living space will be limited. Therefore, choosing new renewable energy and reducing environmental pollution has become a main goal that people deliberately pursue, and the use of new straw energy is one of the important contents. Straw power generation is an important strategic measure to vigorously develop circular economy and use renewable resources to transform the mode of economic growth. Relevant data show that the annual output of crop straw in China is about 700 million tons, ranking first in the world. The annual harvested straw can be used a...
