Description

Continuous sampling device of coal coking Technical Field The utility model relates to the technical field of coking production sampling devices, in particular to a coal coking continuous sampling device. Background Coking is also called high-temperature carbonization of coal, and refers to a coal conversion process which takes coal as a raw material, heats the raw material to about 950 ℃ under the condition of air isolation, produces coke through high-temperature carbonization, simultaneously obtains coal gas and coal tar, and recovers other chemical products. The main application of coke produced by coking coal is iron making, and a small amount of coke is used as chemical raw material for manufacturing calcium carbide, electrodes and the like. In the production process of coal coking, in order to ensure the safety and the environmental protection of production link, the gas that produces in the production process needs to be sampled and detected at the specific position regularly, but current sampling device often is independent component when using, needs to place sampling device in the sampling mouth and operate when the sample, later take off sampling device again and take out the sample and detect, so not only complex operation still can not accomplish continuous sampling, and then influences the efficiency that the sample detected. In view of the above, the present application provides a continuous sampling device for coking coal, which is used for solving the above problems.
