Description

Technical Field

[0001] The utility model relates to the technical field of flue gas detection, in particular to a preprocessing device for flue gas detection. Background Art

[0002] The flue gas detection pretreatment device is a device for pretreating flue gas before flue gas detection. When the pretreatment device is used, the gas in the flue is pumped through the outlet pipe and the sintered filter to filter out the fixed large particles in the flue gas. Then, the gas passes through the first pipe and the air pump, so that the gas passes through the second pipe to the inside of the filter cartridge, and the small solid particles are filtered out through the filter element provided inside the filter cartridge. Then, the gas is discharged to the inside of the detection device through the third pipe for flue gas detection. This can effectively prevent the solid particles inside the flue gas from clogging the detection probe of the detection device.

[0003] In their daily work, the inventors discovered that the pretreatment device for flue gas detection still has at least the following problems: when the pretreatment device is used, the fixed small particles inside the flue gas are finally filtered out by the filter element. However, when the pretreatment device is used for a long time, the fixed small particles accumulate inside the filter element, which leads to a decrease in the working efficiency of the filter element, making it impossible to filter out the fixed particles inside the flue gas well.

When the pretreatment device is used, the gas in the flue 3 is pumped through the air pump 5 through the outlet pipe 2 and the sintered filter 1 to filter out the fixed large particles in the flue 3 gas. Then the gas passes through the first pipe 4 and the air pump 5, so that the gas passes through the second pipe 6 to the inside of the filter cartridge 7, and the small solid particles are filtered out through the filter element 10 provided inside the filter cartridge 7. Then the gas is discharged to the inside of the detection device through the third pipe 11 to detect the flue 3 gas.

[0028] Reference Figure 2 and Figure 3The fixing device 8 includes a first connecting strip 803, the side of the filter cartridge 7 is fixedly connected to the first connecting strip 803, the side of the first connecting strip 803 is provided with a connecting groove 804, the inner wall of the connecting groove 804 is slidably connected with a rectangular plate 806, the side of the rectangular plate 806 away from the connecting groove 804 is fixedly connected to the second connecting strip 805, and the side of the second connecting strip 805 is fixedly connected to the semi-cylinder 801. When using the fixing device 8, the rectangular plate 806 is directly slid into the interior of the connecting groove 804, thereby well setting the semi-cylinder 801 and the filter cartridge 7 together. When the filter element 10 needs to be replaced, the rectangular plate 806 is directly slid out of the connecting groove 804, which makes it very convenient to replace the filter element 10, thereby avoiding the decline in the filtering function of the filter element 10 due to long-term use. A rectangular strip 802 is slidably inserted into the bottom of the side of the filter cartridge 7, and the end of the rectangular strip 802 away from the filter cartridge 7 is fixedly connected to the semi-cylinder 801. By controlling the rectangular strip 80 The sliding movement at the bottom of the side of the filter cartridge 7 allows the rectangular plate 806 to slide smoothly into the interior of the connecting groove 804.

The side of the connecting ring 901 is provided with a slide groove 903, and the inner wall of the slide groove 903 is slidably connected to one end of the C-shaped plate 902. When using the connecting device 9, the C-shaped plate 902 is directly inserted into the inside of the slide groove 903 provided on the side of the connecting ring 901, and then the sintered filter screen 1 is inserted into the inside of the outlet pipe 2, so that the sintered filter screen 1 is well fixed to the inside of the outlet pipe 2.

The second spring 906 is fixedly connected to the C-shaped plate 902 at one end thereof, and the connecting rod 905 is pulled by the second spring 906 to restrict the positioning plate 907 to the inside of the rectangular groove 908.

[0030] Working principle: when using the pretreatment device, the gas in the flue 3 is pushed through the outlet pipe 2 and the sintered filter 1 by the air pump 5 to filter out the fixed large particles in the flue 3 gas, and then passes through the first pipe 4 and the air pump 5, so that the gas passes through the second pipe 6 to the inside of the filter cartridge 7, and the solid small particles are filtered out by the filter element 10 arranged inside the filter cartridge 7, and then the gas is discharged to the inside of the detection device through the third pipe 11 for detection of the flue 3 gas. This can effectively prevent the solid particles inside the flue 3 gas from clogging the detection probe of the detection device. When using the fixing device 8, the rectangular plate 806 is directly slid into the inside of the connecting groove 804, and then the U-shaped plate 810 is squeezed by the first spring 809, so that the U-shaped plate 810 is sleeved on the top of the rectangular plate 806, and then the round rod 811 is inserted into the top of the rectangular plate 806. In this way, the rectangular plate 806 can be well fixed inside the connecting groove 804, and the semi-cylinder 801 and the filter cartridge 7 can be well set together. When the filter element 10 needs to be replaced, the operation can be reversed. This makes it very convenient to replace the filter element 10, thereby avoiding the decline in the filtering function of the filter element 10 due to long-term use.
