Embodiment 1

[0024] A coking company has 3 coke ovens, with an annual output of 3 million tons of coke and 1.6 billion m of coke oven gas 3 , through this sampling device and detection method, the sulfide in the imported coke oven gas is sampled and detected. The gas volume is 200L, and the measured hydrogen sulfide content is 4.81g / m 3 , carbon disulfide content 805mg / m 3 , COS content 496mg / m 3 , other sulfides are small, negligible, that is, the total sulfur content is 5.47g / m 3 , and on-site desulfurization product sulfur content analysis, the result error is within 10%.

[0025] After the coke oven gas is purified by the desulfurization device, the sulfide in the exported coke oven gas is sampled and tested. The gas volume is 200L, and the measured hydrogen sulfide content is 210mg / m 3 , carbon disulfide content 97mg / m 3 , COS content 62mg / m 3 , by calculating the total sulfur content, it is 197.8mg / m 3 , slightly higher than the SO after combustion of the gas-fired boiler 2 Co...

Abstract

The invention discloses an online sampling system, particularly discloses an online sampling system for measuring the total S content in coke oven gas, and belongs to the technical field of design andmanufacturing of coke oven gas production and detecting equipment. According to the online sampling system for measuring the total S content in the coke oven gas, the total S content in the gas produced in the coal coking process can be detected accurately. The online sampling system comprises a filter impurity-clearing device, a dewatering device, an absorption sampling device and a dischargingdevice which sequentially communicate, and the online sampling system is connected into a coke oven gas conveying pipe needing to be sampled through the filter impurity-clearing device.

Description

technical field [0001] The invention relates to an online sampling system, in particular to an online sampling system for measuring the total S content of coke oven gas, and belongs to the technical field of design and manufacture of coke oven gas production testing equipment. Background technique [0002] Coke oven gas is a high calorific value flammable gas produced by high-temperature dry distillation of coal in isolation from the air. During the coking process of coal, about 30% to 35% of the sulfur in the raw coal is converted into sulfides such as hydrogen sulfide, and the sulfides are converted into inorganic sulfides and organic sulfides. The main form of inorganic sulfur is hydrogen sulfide. The chemical formula is h 2 S; organic sulfur is carbon disulfide chemical formula CS 2 The chemical formula of carbon oxysulfide is COS, the chemical formula of mercaptan is RSH, the chemical formula of thioether is R-S-R' and the chemical formula of thiophene is C 4 h 4 Su...
