Embodiment 1

[0025] A test method for the gas rate and composition of calcium carbide dust when it is wet, such as figure 1 As shown, the main content of the present invention is a test method for the release rate and composition analysis of the flammable and explosive gas released by the reaction of water vapor and calcium carbide dust, which can generate water vapor with different humidity and simulate the actual working conditions of the calcium carbide production device. At the same time, the existing test method for the rate of flammable gas emission when wet is improved. The test system for the gas rate and composition of calcium carbide dust when it is wet is mainly composed of the following parts:

[0026] 1) Steam generator: connected with the steam premixer for producing steam.

[0027] 2) Steam generator control valve: connected with the steam generator and the steam premixer, used to connect and shut off the steam from the steam generator to the steam premixer.

[0028] 3) Wa...

Abstract

The invention relates to a method of testing release rate and composition of gas released by calcium carbide dust upon contact with moisture, and mainly solves the problem of the prior art where detection of the release rate and composition of flammable explosive gas produced by reaction of calcium carbide dust with water vapor has poor effect. The method used herein is characterized in that an apparatus of testing release rate and composition of gas released by calcium carbide dust upon contact with moisture is used to test the release rate and composition of the gas released by the calcium carbide dust upon contact with moisture, the apparatus comprises a water vapor premixer, a precision moisture meter, a calcium carbide dust raising unit, a calcium carbide dust raising controller, a gas release rate test system, a gas composition test system and a computer control system, the water vapor premixer is capable of generating water vapors of different humidities, and the water vapor premixer is connected with the precision moisture meter; by using the above technical scheme, the problem above is well solved; the method is applicable to the test on release rate and composition of gasreleased by calcium carbide dust upon contact with moisture.

Description

technical field [0001] The invention relates to a method for testing the gas rate and components of calcium carbide dust released when it is wet. Background technique [0002] In recent years, with the rapid development of my country's calcium carbide industry, the annual output has been rising steadily, but the traditional calcium carbide production process requires a lot of manual operations, which is inefficient and complicated to operate. The workers of the enterprise need to carry out high-intensity operations under the harsh conditions of high temperature and high dust, which poses great safety hazards. The calcium carbide dust removal system plays a key role in reducing the dust hazards in the process of calcium carbide extraction and ensuring the occupational health of dust collectors. However, because the dust contains incompletely reacted calcium carbide, and the carbon monoxide and hydrogen in the calcium carbide furnace may be partly carried out during the proce...
