The sampled gas is sent to the flue gas pretreatment system in the CEMS cubicle through an electrically heated self-limiting temperature sampling pipe, and then sent to the flue gas analysis instrument. Due to the long-term heating state of the electrically heated self-limiting temperature sampling pipe, its own aging is fast, the temperature cannot reach the actual demand, resulting in crystallization blockage in the sampling pipe, affecting the measurement of environmental protection data, and the average service life is only 1-2 years. Therefore, it is necessary to preprocess it, so a new type of CEMS direct sampling pretreatment device needs to be set up.

[0003] When using the new type of CEMS direct sampling pretreatment device, the electrically heated self-limiting temperature sampling pipe of the direct extraction method sampling system is frequently blocked, has a short service life, and the replacement labor cost and equipment cost are relatively high.
