A clean and environmentally friendly toxic gas vocs efficient treatment device

Abstract

The invention discloses a clean and environmental-friendly efficient disposal device for toxic gas VOCs. The clean and environmental-friendly efficient disposal device for toxic gas VOCs comprises a shell. A liner is arranged in the shell, a cushion block is connected to the bottom surface of an inner cavity of the shell, the top surface of the cushion block is connected to the bottom surface of the liner, a distraction block is connected to the inner wall of the shell, the other face of the distraction block is connected to the outer surface of the liner, insulating cotton is arranged in a cavity between the shell and the liner, a fixed bar is connected to the top of the shell, and a flue gas hood is connected to the top end of the fixed bar. A tar scraping device is driven by an eliminating device to operate, so that the tar scraping device can scrape ash on the inner wall of an inner hexagonal catalyst hole to make sure that the inner wall of the inner hexagonal catalyst hole can bein full contact with exhaust gas, and the contact area of a catalyst and exhaust gas is constant, and therefore, the catalytic combustion speed is increased and the disposal effect is better. No toxic gas VOCs is remained in the disposal gas, so that the clean and environmental-friendly efficient disposal device is good in environmental-friendliness, and the practicality of the clean and environmental-friendly efficient disposal device for toxic gas VOCs is improved.

Description

technical field [0001] The invention relates to the field of gas processing equipment, and more specifically, relates to a device for efficiently processing clean, environmentally friendly and toxic gas VOCs. Background technique [0002] Exhaust gas refers to the toxic and harmful gases emitted by human beings in the process of production and life, such as the exhaust gases emitted by chemical plants, steel plants, pharmaceutical factories, coking plants and oil refineries, etc. These exhaust gases contain toxic gas VOCs, which makes the exhaust gas smell Larger, which seriously pollutes the environment and affects human health. Here, VOCs are also called volatile organic compounds, which refer to the saturated vapor pressure at room temperature greater than 70.91Pa, the boiling point below 50-260°C under the standard atmospheric pressure of 101.3kPa and the initial boiling point equal to 250°C. organic compounds, or any organic solid or liquid that can be volatilized at no...

Problems solved by technology

[0003] The existing toxic gas VOCs treatment device designed according to the catalytic combustion method is composed of a casing, a catalytic reaction part, a heater, a heat exchanger, etc., wherein the catalytic reaction part is made by spraying a precious metal catalyst on the inner surface of a honeycomb carrier. However, during use, the catalytic combustion of toxic gas VOCs on the surface of the catalyst will form carbonaceous ash, which adheres to the inner wall of the catalyst hole and covers the catalyst, reducing the contact area between the catalyst and the exhaust gas, resulting in catalytic combustion. The speed slows down, the treatment effect becomes worse, and the residual toxic gas VOCs in the treated gas is more, polluting the environment, and some carbon-containing ash will move with the air flow and adhere to the surface of the heat exchanger, making the heat exchanger The reduction of heat transfer efficiency leads to a gradual decrease in heat utilization rate, a gradual increase in energy consumption, and a high cost of waste gas treatment. Therefore, it is urgent to design a clean, environmentally friendly and efficient treatment device for toxic gas VOCs
