Double-wire drying combustion tower and combustion method thereof

Abstract

The invention discloses a double-wire drying combustion tower which comprises a combustion box body. A combustion cavity capable of prolonging the combustion time, a combustion gas gathering cavity used for gathering combustion gas and a cooling cavity used for cooling combusted gas are formed in a combusting cavity of the combustion box body in sequence from bottom to top. A control box used for controlling the temperature of the combustion box body is arranged on the front side or the rear side of the combustion box body. By means of the double-wire drying combustion tower and the combustion method thereof, a bottom-to-top layer-by-layer combustion manner is adopted, ventilation partition plates are arranged in a staggered manner, so that the time for waste gas particles to pass through each combustion area is prolonged, the waste gas particles can be combusted more sufficiently in each combustion area, and gas discharged afterwards reaches the marked discharging grade. By means of the combustion manner of the combustion tower, discharging of the waste gas particles can be greatly reduced, discharged gas can be more environment-friendly, all dust generated after combustion of the particles can be thoroughly removed through a dust collector, and collecting and cleaning of the combustion tower are facilitated.

Description

technical field

[0001] The invention relates to waste gas combustion equipment, in particular to a double-line drying combustion tower. Background technique

[0002] When chemical vapor deposition (CVD) techniques are used in the solar cell manufacturing industry and in the manufacture of integrated circuits and electronic components, to prevent pollution and fire, it is necessary to avoid the release of used gases into the atmosphere and / or the production of these processes. gas. Certain gas compounds in these exhaust gases are toxic to humans, are flammable when in contact with air at high temperatures, and can spontaneously burn even when in contact with air or any oxidant at normal temperature. . The traditional equipment for dealing with these harmful gases mainly uses the method of burning flammable gases to burn harmful gases. The disadvantages of this method are: high operating costs, and harmful exhaust gases are prone to appear when flammable gases are extinguish...
