For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0043] In the field of high temperature gas sampling, the commonly used gas sampler in the prior art only adopts a single sampling tube, which has a relatively primitive structure. The flue gas collected by the gas sampler is only the gas from a single part of the gas to be measured.

[0044] The disadvantage is that the collected gas composition cannot represent the full picture of the gas being measured, and sampling is only done by one sampling tube, and the sampling volume is very small in a short time, which is not convenient for chemical analysis of the gas sample.

[0045] like Figure 1 , 3 As shown, a multi-point sampler capable of preventing dust clogging comprises: a sampling tube 1, a cooling mechanism 2, and a filtering mechanism 3;

[0046] The cooling mechanism 2 is arranged inside the wall of the sampling tube 1 and is used to cool the gas passing through the sampling tube 1;

[0047] The filter mechanism 3 is arranged at one end of the back side of the sampling tube 1 and is used to filter dust particles in the gas;

[0048] The filter mechanism 3 includes: a connecting pipe 31, a filter chamber 32, and a filter plate 33;

[0049] The connecting tube 31 is fixedly connected to one end of the back of the sampling tube 1 for connecting the gas;

[0050] The filter chamber 32 is fixedly connected to the back side of the connecting pipe 31 , and the filter plate 33 is fixedly connected to the inner wall of the filter chamber 32 . The filter plate 33 is used for filtering gas.

[0051] Specifically, the smoke inhaled by the sampling tube 1 is connected by setting a connecting tube 31, and filtered through the filter plate 33 on the inner wall of the filter chamber 32 to facilitate interception of dust particles in the smoke, so as to avoid dust particles mixed in the sampled smoke and affect subsequent smoke detection.

[0052] like Figure 3 As shown, the filter plate 33 is V-shaped.

[0053] Specifically, by setting the filter plate 33 into a V shape, the filter plate 33 intercepts dust particles in the flue gas when filtering, making it difficult for the dust particles to adhere to the surface of the filter plate 33 and slide out of the filter plate 33 through the inclined surfaces on both sides of the V shape to avoid clogging of the filter plate 33.

[0054] like Figure 3 As shown, the filtering mechanism 3 further includes a chute 34 and a collecting frame 35;

[0055] The two groups of collecting frames 35 are slidably connected to the two sides of the filter bin 32 through the provided slide grooves 34 , respectively. The back of the collecting frames 35 is provided with filter holes, and the collecting frames 35 are used to collect dust particles.

[0056] Specifically, the collecting frame 35 is provided to facilitate the collection of dust particles sliding out of the inclined surface of the filter plate 33 , and the chute 34 is provided to allow the collecting frame 35 to be withdrawn, so that the dust particles can be processed in a centralized manner.

[0057] like Figure 2 As shown, the cooling mechanism 2 includes a cooling pipe 21;

[0058] The cooling tube 21 is buried in the tube wall of the sampling tube 1 and is used for the flow of cooling medium.

[0059] Specifically, the cooling medium in the cooling pipe 21 absorbs the heat in the flue gas, thereby achieving a cooling effect, so as to prevent the flue gas temperature from being too high and easily damaging the equipment.

[0060] like Figure 2 As shown, the cooling tube 21 is spiral.

[0061] Specifically, by arranging the cooling tube 21 in a spiral shape, the contact area with the tube wall can be increased to improve the heat absorption efficiency.

[0062] like Figure 2 As shown, the cooling mechanism 2 includes a circulation pipe 22 and a water inlet joint 23;

[0063] The circulation pipe 22 is in communication with the cooling pipe 21 . The outer wall of the circulation pipe 22 is connected with two groups of water inlet joints 23 . The water inlet joints 23 are used to inject cooling medium.

[0064] Specifically, the water inlet joint 23 is provided to cooperate with the circulation pipe 22 to facilitate the access of new cooling medium, so as to avoid the temperature in the cooling pipe 21 from increasing and affecting the cooling effect.

[0065] like Figure 2 , 4 As shown, the cooling mechanism 2 includes an inner cylinder 24;

[0066] The inner cylinder 24 is detachably connected to the inner wall of the sampling tube 1 .

[0067] Specifically, a detachable inner cylinder 24 is provided on the inner wall of the sampling tube 1 to facilitate removal of the inner cylinder 24 for cleaning, thereby preventing residual impurities from adhering to the inner wall of the sampling tube 1 and affecting subsequent use.

[0068] The working principle of the utility model is as follows:

[0069] The smoke inhaled by the sampling tube 1 is connected by setting a connecting pipe 31, and filtered through the filter plate 33 on the inner wall of the filter chamber 32, so as to intercept dust particles in the smoke, so as to avoid dust particles mixed in the sampled smoke and affect the subsequent smoke detection. By setting the filter plate 33 into a V shape, the filter plate 33 intercepts the dust particles in the smoke when filtering the smoke, so that the dust particles are difficult to adhere to the surface of the filter plate 33, and slide out of the outside of the filter plate 33 through the inclined surfaces on both sides of the V shape to avoid clogging of the filter plate 33. By setting a collection frame 35, it is convenient to collect the dust particles sliding out of the inclined surface of the filter plate 33 By setting a slide 34, the collection frame 35 can be pulled out to centrally process the dust particles. The cooling medium of the cooling pipe 21 absorbs the heat in the flue gas to achieve a cooling effect to avoid the high temperature of the flue gas, which may easily damage the equipment. The water inlet joint 23 and the circulation pipe 22 are arranged to facilitate the connection of new cooling medium to avoid the temperature in the cooling pipe 21 from rising and affecting the cooling effect. A removable inner cylinder 24 is arranged on the inner wall of the sampling tube 1 to facilitate the removal of the inner cylinder 24 for cleaning, so as to avoid residual impurities adhering to the inner wall of the sampling tube 1 and affecting subsequent use.
