Organic waste gas catalytic combustion integrated device

Abstract

The invention belongs to the field of environment protection, and relates to an organic waste gas catalytic combustion integrated device. The device comprises an organic waste gas pretreatment system,a heat exchanger, a heating chamber, a catalytic combustor and an air volume adjusting device which are sequentially arranged in the body and further comprises a control system arranged on the body.After being filtered through the organic waste gas pretreatment system, organic waste gas enters the heat exchanger, indirect energy exchange is conducted on the organic waste gas and high-temperaturegas obtained after the catalytic reaction, and the temperature of the waste gas is increased for the first time at the time; the organic waste gas with a certain temperature enters the heating chamber, and the temperature of the organic waste gas is increased to the best catalytic reaction temperature; the temperature meets the catalytic reaction temperature requirement, the organic waste gas enters the catalytic combustor and is thoroughly decomposed, and meanwhile a large amount of heat is released; and heat energy of purified gas is converted to pretreated organic waste gas through the heat exchanger, and emptying is conducted after cooling. The device has the characteristics of being high in universality and low in energy consumption.

Description

Technical field [0001] The invention relates to exhaust gas catalytic combustion treatment technology and belongs to the field of environmental protection. In particular, it relates to an organic waste gas catalytic combustion integrated device. Background technique [0002] With the increasing development of modern industry, the pollution of organic waste gas to the environment is becoming more and more serious, especially in the coating, dye, spray paint, printing, automobile, household appliances, chemical and other industries. A large amount of organic waste gas will be generated during the production process, which contains nitrogen. Organic matter (containing ammonia) is one of the main components. However, existing catalytic combustion devices usually use precious metal catalysts, which can decompose organic matter into water and carbon dioxide. However, when organic waste gas contains nitrogen-containing organic matter, a large amount of nitrogen oxides will be produced,...

Problems solved by technology

The device has high energy consumption and the effect is not given

The implementation of the treatment device described in the above patents is relatively complicated, the energy consumption is high, and the discharge of pollutants at the outlet cannot be guaranteed to meet the standards.

Nitrogen-containing organic matter catalytic combustion catalyst is a kind of catalyst that adopts the principle of catalytic combustion to treat nitrogen-containing organic matter in organic waste gas. There is no device in the prior art that uses nitrogen-containing organic matter catalytic combustion catalyst to treat organic waste gas.
