A humidifier for humidifying gas containing sulfur dioxide

Abstract

The name of the invention is a humidifier for humidifying sulfur dioxide-containing gas. The utility model belongs to the technical field of engineering and environmental protection technology experimental equipment. It mainly provides a device for humidifying sulfur dioxide-containing gas for desulfurization technology research. Its main features are: it includes a gas-liquid mixing tank with a thermal insulation jacket; a heating jacket is provided inside the thermal insulation jacket, and a thermocouple is installed in the gas-liquid mixing tank; the gas-liquid mixing tank is equipped with an air inlet pipe and an air outlet pipe. The outlet port of the gas pipe is located at the lower part of the gas-liquid mixing tank, and the inlet port of the gas-liquid mixing tank is located at the top of the gas-liquid mixing tank; a drain pipe is installed at the bottom of the gas-liquid mixing tank, and a manual ball valve is installed on the drain pipe; There is a float switch and a connecting water pipe, and the water pipe between the float switch and the drain pipe is connected with a water inlet pipe and a solenoid valve. The invention has the characteristics of making the water vapor content in the simulated flue gas meet the requirements of the experimental design, and is mainly used for humidifying the gas containing sulfur dioxide.

Description

technical field [0001] The invention belongs to the technical field of chemical engineering and environmental protection technology experimental equipment, relates to the humidification of simulated flue gas in the chemical industry, and in particular relates to a 2 Experimental device for humidification of other corrosive gases. Background technique [0002] In recent years, my country's sulfuric acid industry has developed rapidly, and pollutant emissions have continued to increase. In 2007, the annual amount of waste gas emitted by the sulfuric acid industry in China was 122.3 billion m3 3 , accounting for 4.0% of the chemical industry emissions; SO 2 The total emission is about 100,000 tons, accounting for 0.4% of the national emission and accounting for SO 2 9.0% of the total emission, which is a larger SO 2 Emission source. At present, sulfuric acid industrial enterprises adopt the two-turn-two-suction process or add a tail gas desulfurization device on the basis ...
