Embodiment Construction
[0020] The present invention will be further described below in conjunction with accompanying drawing.
[0021] Such as figure 1 shown. A humidifier used for humidifying sulfur dioxide-containing gas according to the present invention includes a gas-liquid mixing tank 2 with a thermal insulation jacket, the gas-liquid mixing tank 2 is a quartz glass tank body, and the thermal insulation jacket is composed of a thermal insulation material 4 and a stainless steel shell 5. The gas-liquid mixing tank 2 of the thermal insulation coat is contained on the support 6. A heating jacket 3 is arranged in the heat-insulation jacket outside the gas-liquid mixing tank 2, and a thermocouple 7 is arranged in the gas-liquid mixing tank 2. The heating jacket 3, the thermocouple 7 and the temperature controller form a temperature control system. Gas-liquid mixing tank 2 is equipped with inlet pipe 1, outlet pipe 8, and the outlet port of inlet pipe 1 is positioned at gas-liquid mixing tank 2 bo...

The invention relates to a humidifier for humidifying gas containing SO2 and belongs to the technical field of experiment equipment of chemical engineering and environment protection. The humidifier is mainly used for humidifying the gas containing SO2 in desulfurization technology. The humidifier mainly includes following units: a gas-liquid mixing pot having a heat-insulating jacket; a heating jacket arranged in the heat-insulating jacket; a thermoelectric couple arranged in the gas-liquid mixing pot; a gas inlet pipe and a gas outlet pipe arranged on the gas-liquid mixing pot, wherein a gas outlet end of the gas inlet pipe is arranged on the bottom of the gas-liquid mixing pot and the gas inlet end of the gas outlet pipe is arranged on the top of the gas-liquid mixing pot; a water discharge pipe arranged on the bottom of the gas-liquid mixing pot and provided with a manual ball valve; and a float switch and a connecting water pipe arranged between the gas outlet pipe and the water discharge pipe, wherein a water inlet pipe and an electromagnetic valve are connected to the water pipe between the float switch and the gas outlet pipe. The humidifier enables the content of water vapor in simulative flue gas to achieve an experiment design required value and is mainly used for humidifying the gas containing SO2.
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 more specifically relates to a 2 Experimental device for humidification of 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, China's sulfuric acid industry emitted 122.3 billion m3 of waste gas annually. 3 , accounting for 4.0% of the emissions from the chemical industry; SO 2 The total emission is about 100,000 tons, accounting for 0.4% of the national emission, accounting for SO 2 9.0% of the total emission is the larger SO 2 Emission source. At present, sulfuric acid industrial enterprises adopt a two-turn-two-suction process or add a tail gas desulfurization device on the basis of a one-turn-one-sucti...
