Automatic device for measuring sulfur dioxide capacity of active coke with continuous method

Abstract

The invention discloses an automatic device for measuring sulfur dioxide capacity of active coke with a continuous method. The automatic device comprises a flue gas mixing device, a water vapor generating device, a gas mixing device and a reaction tube, wherein the flue gas mixing device comprises a premixer; the water vapor generating device comprises a pump, a vaporizer and a gas flow meter, and water enters the vaporizer for vaporization via the pump; mixed gas is obtained after gas at an outlet of the premixer and water vapor after vaporization by the vaporizer enter the gas mixing device and enters the reaction tube via a pipeline; a resistance wire and a distribution plate are arranged in the reaction tube, the mixed gas is fully contacted with activated coke in the reaction tube, and the mixed gas after adsorption by the activated coke is discharged out of the reaction tube. Compared with existing devices, the automatic device has the characteristics that the sulfur dioxide adsorption capacity of the activated coke can be measured automatically, the gas component composition is accurate and stable, the integration level is high, the operation is convenient and quick and the like, and the method has positive significance in solving the problem of high difficulty in measurement of adsorption capacity of the activated coke at present.

Description

technical field [0001] The invention relates to environmental protection technology equipment for pollutant adsorption capacity, and is particularly suitable for the field of activated coke adsorption capacity of gas pollutants. Background technique [0002] In recent years, the industrial application of adsorption to remove gas pollutants has become more and more widespread, such as flue gas desulfurization, sugar decolorization, oil and gas recovery, wastewater treatment, etc. At the same time, activated coke, activated carbon, molecular sieve, diatomite, etc. The adsorption effect and capacity in actual industrial applications urgently need quantitative and qualitative evaluation. At present, there is a shortage of analytical and testing instruments with strong pertinence and relatively narrow fields in this industry. The error is relatively large. For continuous operation industrial devices, the labor cost of this intermittent device is relatively high, and it is difficu...
