Benefits of technology

The technical purpose described by this patented technology is that it allows for effective removal or destruction of harmful gases from exhaust gas streams while minimizing production cost compared to previous methods like absorption into liquid solvents. This makes them more efficient than current technologies such as incinerators.

Problems solved by technology

This patented technical solution described in the patents describes various ways to remove harmful gases from industrial processes or environmental concerns such as emissions caused by volatilization during burning process. These techniques include use of different types of materials like activated carbon carriers, metal carbons, ceramics, porous silica, zeolite, lithium ion batteries, iron based panel products, and cathode ray tubes. However, each technique requires an expensive apparatus installation due to their complexity structure and poor performance compared to traditional technologies. Therefore, finding alternative solutions without requiring excessively long periods of time and expenses would help address issues related to emission control standards.

Abstract

The invention relates to a heat accumulating type oxidation device for catalysis denitration. The heat accumulating type oxidation device comprises heat accumulation chambers and an oxidation chamber. The oxidation chamber is fixedly installed on the tops of the multiple heat accumulation chambers. A combustor and an explosion door are arranged on the oxidation chamber. A heat accumulating body layer is installed inside each heat accumulation chamber. An air inlet pipeline, an air exhaust pipeline, an air inlet valve and an air exhaust valve are fixedly connected below each heat accumulation chamber. A catalysis reducing agent layer and a reduced product nozzle are further installed inside each heat accumulation chamber. The reduced product nozzles are connected with a liquid reduced product pipeline and installed above the catalysis reducing agent layers and spray reduced products to the catalysis reducing agent layer. A valve is installed on the liquid reduced product pipeline. The heat accumulating type oxidation device is reasonable in structure, low in manufacturing and operation cost, small in occupied area, good in energy-saving effect, capable of efficiently treating VOCs and NOx at the same time, and ideal.
