The air inlet pipe 102 on the tail gas recovery treatment box 1 is connected to a tail gas pipeline used in the industrial production process, so that the tail gas can enter the tail gas recovery treatment box 1 from the air inlet pipe 102, and then the pipeline for heat energy recovery is connected to the air outlet pipe 103 on the tail gas recovery treatment box 1, so as to achieve the effect of tail gas heat energy recovery and reuse. A mounting plate 2 is installed on one side of the inside of the tail gas recovery treatment box 1, a rack 201 is installed at the center of the inside of the mounting plate 2, and an exhaust fan 202 is installed in the rack 201. The rack 201 is fixedly installed on one side of the inside of the tail gas recovery treatment box 1 by the mounting plate 2 and is close to the air outlet pipe 103. According to the exhaust fan 202 in the rack 201, the efficiency of discharging the tail gas into the tail gas recovery treatment box 1 can be improved, the tail gas residence time is reduced, and the situation that the tail gas temperature accumulates quickly after residence is also reduced.

[0024] The other side of the inside of the tail gas recovery treatment box 1 is provided with a moving frame 3, which is located between the two groups of U-shaped sliding rails 101. The top and bottom of the moving frame 3 are provided with guide seats 301, and the outer wall of the guide seat 301 is connected with the inner wall of the U-shaped sliding rail 101 in a sliding manner. The inside of the moving frame 3 is provided with dust removal filter plates 302 on both sides. The moving frame 3 is pushed into the two groups of U-shaped sliding rails 101 in the tail gas recovery treatment box 1 in a sliding manner by the guide seat 301, and the dust removal filter plates 302 are installed on both sides of the inside of the moving frame 3. According to the two groups of dust removal filter plates 302, the filter mesh on the left side is larger than the filter mesh on the right side, so that the industrial tail gas inlet pipe 102 enters the tail gas recovery treatment box 1 and is filtered layer by layer by the two groups of dust removal filter plates 302, so as to avoid the influence of high content of dust or other particulate matters in the flue gas on the later heat energy recovery. A motor 303 is installed on the center of one side of the moving frame 3. The output shaft of the motor 303 is fixedly connected with one end of a rotating shaft 304 through a coupling. The outer wall of the rotating shaft 304 is provided with mounting frames 305 on both sides. A brush 306 is installed on the outer wall of one side of the mounting frame 305.

According to the fixed connection of the output shaft of the motor 303 with one end of the rotating shaft 304 through the coupling, the motor 303 drives the rotating shaft 304 to rotate forward or reverse, which can synchronously drive the two groups of brushes 306 to clean the dust or other particulate matters accumulated on the surfaces of the dust removal filter plates 302, so as to avoid the influence of the high content of dust or other particulate matters accumulated on the surfaces of the dust removal filter plates 302 on the filtering effect, and also avoid the need for high-power suction of the tail gas due to the high content of dust or other particulate matters on the surfaces, which increases the power consumption. By cleaning the dust removal filter plates 302 at irregular intervals, the normal flow of the tail gas is ensured, the power consumption is reduced, the energy saving and the efficiency of the tail gas recovery heat energy are improved. During the period, there is no need to involve relevant technical personnel for cleaning, which reduces the workload and work load of the personnel involved. At the same time, according to the dust or other particulate matters cleaned out, they can fall into the dust collection boxes 307, and finally they can be cleaned uniformly. The opening frequency of the motor 303 can be set according to the actual needs, and the motor 303 does not need to work all the time, which reduces the energy consumption of the motor 303.

[0025] Working principle: when using the utility model, the inlet pipe 102 on the tail gas recovery treatment box 1 is connected to the tail gas pipeline used in the industrial production process, so that the tail gas can enter the tail gas recovery treatment box 1 from the inlet pipe 102, and then the outlet pipe 103 on the tail gas recovery treatment box 1 is connected to the pipeline for heat energy recovery, achieving the effect of tail gas heat energy recovery and reuse. By installing the rack 201 on the installation plate 2 and fixing it on the inside of the tail gas recovery treatment box 1, close to the outlet pipe 103, according to the exhaust fan 202 in the rack 201, the efficiency of tail gas entering the tail gas recovery treatment box 1 can be improved, the tail gas residence time is reduced, and the situation of rapid loss of tail gas temperature after residence is also reduced. By sliding the moving frame 3 into the two groups of U-shaped sliding rails 101 in the tail gas recovery treatment box 1 through the guide seat 301, and installing the dust removal filter plates 302 on the inside of the moving frame 3, according to the two groups of dust removal filter plates 302, the left filter screen hole is larger than the right filter screen hole, so that the industrial tail gas enters the tail gas recovery treatment box 1 through the inlet pipe 102, and is filtered layer by layer by the two groups of dust removal filter plates 302, so as to avoid the situation that the high content of dust or other particulate matters in the flue gas affects the later heat energy recovery and utilization. According to the fixed connection between the output shaft of the motor 303 and one end of the rotating shaft 304 through the coupling, the motor 303 drives the rotating shaft 304 to rotate forward or reverse, which can synchronously drive the two groups of brushes 306 to clean the dust or other particulate matters accumulated on the surface of the dust removal filter plate 302, so as to avoid the situation that the high content of dust or other particulate matters on the surface of the dust removal filter plate 302 affects the filtering effect, and also avoid the situation that the high content of dust or other particulate matters on the surface requires high-power suction of tail gas, resulting in increased power consumption. By cleaning the dust removal filter plate 302 at irregular intervals, the normal flow of tail gas is ensured, the power consumption is reduced, the energy saving and the efficiency of tail gas recovery heat energy are improved, during which no related technical personnel is needed for cleaning, the workload and operation safety risk of the related personnel are reduced, and according to the dust or other particulate matters cleaned out, they can fall into the dust collection box 307, which can be cleaned uniformly at last. The opening frequency of the motor 303 can be set according to the actual needs, without the motor 303 working all the time, reducing the power consumption of the motor 303, and effectively improving the use effect of the tail gas heat energy saving and recovery tail gas treatment device.
