As shown in Fig. 1, Fig. 2 and Fig. 3, a kind of can more accurately detect the total sulfur content in the coal gas that produces in the coal coking process provided by the present invention and be used for coke oven gas total S content measurement online sampling system. The on-line sampling system includes a filter cleaning device 1, a water removal device 2, an absorption sampling device 3 and a discharge device 4, and the filter cleaning device 1, a water removal device 2, an absorption sampling device 3 and a discharge device 4 are sequentially Connected, the online sampling system is connected to the coke oven gas delivery pipe that needs to be sampled through the filtering and cleaning device 1 . The present application sets up a set of on-line sampling system including filter cleaning device, water removal device, absorption sampling device and discharge device, and connects the filter cleaning device, water removal device, absorption sampling device and discharge devic...

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.

[0023] Example one

[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 , The sulfide in imported coke oven gas is sampled and tested by this sampling device and detection method. 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 trace amounts and can be ignored, that is, the total sulfur content is 5.47g/m 3 , And analysis of the sulfur content of the on-site desulfurization product, the result error is within 10%.

[0025] After the coke oven gas is purified by the desulfurization device, the sulfide in the outlet 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 SO after combustion of gas boiler 2 Calculated concentration of 180mg/m 3 , The error is within 10%.

[0026] Through this sampling device and the detection of the components of each solution, relatively accurate data is basically obtained, which provides reference design values for on-site deep desulfurization and gas reuse, reduces the investment cost of deep desulfurization, and ensures the desulfurization effect, which has reached the reuse requirements.
