[0019] Compared with the prior art, the beneficial effect of the present utility model is that the tail gas treatment device with a sampling mechanism

[0020] (1) In this case, through the set sampling and detection structure, the situation in the above solution where there is no sampling and treatment of the filtered tail gas, and thus it is impossible to confirm whether the treated tail gas is completely treated, is solved. When it is necessary to sample and detect the treated tail gas, at this time, the operator controls the other control check valve to close, and then the operator controls the check valve and the negative pressure machine to operate. When the negative pressure machine is operating, it transports the treated tail gas into the sampling chamber for sampling and detection. When the treated tail gas is transported into the sampling chamber, at this time, the tail gas detector detects and processes the treated tail gas. When the tail gas detection is normal, the control check valve is opened to discharge the tail gas. When the tail gas detection is abnormal, the alarm operates to alarm and notify the operator to replace the components in the tail gas treatment device body;

[0021] (2) Through the set tail gas treatment structure, the situation where leakage is likely to occur during tail gas sampling and the tail gas is normally discharged into the sampling chamber is solved. When the tail gas is normally discharged, at this time, the tail gas is transported through the outlet pipe and the connecting pipe into the flange outlet pipe for discharge. When the tail gas needs to be sampled and detected, at this time, the tail gas is transported through the outlet pipe into the sampling chamber for sampling and detection. At the same time, when the sampling chamber samples and detects the tail gas, it is convenient for the normal discharge and treatment of other tail gases. Description of the Drawings
