The same mesh plate is fixed to the inner walls on both sides of the treatment box by bolts. Packing materials are arranged on the outer wall of the top of the mesh plate. A spray rack is fixed to the inner wall of the top of the treatment box by bolts. After the water sprayed out is filtered by the filter screen on the sliding plate, it is circularly sprayed through a water pump, so as to avoid clogging the pipeline due to impurities in the water after spraying. The impurities filtered out on the sliding plate can be easily cleaned through the sliding plate.

[0004] However, when the above waste gas treatment device for a gas turbine power generation device is actually used, when treating the waste gas generated by a gas generator device, it only filters the dust and impurities in the waste gas, and cannot effectively recover and utilize the waste heat in the waste gas, which will cause a large amount of energy waste.

[0021] In this embodiment, a plurality of mounting ears 102 are symmetrically arranged at the bottom of the processing box 101, and a detachable cover plate 103 is arranged at the top. An exhaust pipe 104 is welded to the top of the cover plate 103. The mounting ears 102 will facilitate the mechanism to be fixed by bolts. The cover plate 103 is installed on the top of the processing box 101 by bolts. The exhaust pipe 104 is welded to the cover plate 103, and the flange at the top can be connected to the exhaust gas discharge pipe.

[0022] Among them, the intake pipe 105 is fixedly connected to the processing box 101 and is located at the front lower side of the processing box 101. The receiving box 106 is detachably connected to the processing box 101 and is located below the intake pipe 105. The flow guide plate 107 is fixedly connected to the processing box 101 and is located inside the processing box 101 and above the filter assembly. The heat exchange tube 108 is composed of a rectangular plate 1081 and a serpentine tube 1082. The rectangular plate 1081 is fixedly connected to the processing box 101, and the serpentine tube 1082 is welded to the rectangular plate 1081 and is located above the rectangular ventilation cavity of the flow guide plate 107. The filter assembly is arranged between the intake pipe 105 and the flow guide plate 107. The flange on the air outlet side of the intake pipe 105 is fixed to the outside of the air inlet of the processing box 101 by bolts, and the flange on the air inlet side is flange-connected to the exhaust gas input pipe flange. A rectangular chute is arranged at the bottom of the processing box 101 to facilitate the installation of the receiving box 106. The receiving box 106 can collect the dust and impurities generated when the filter assembly filters the exhaust gas. The flow guide plate 107 is fixed to the inner wall of the processing box 101 by bolts. The rectangular plate 1081 is fixed in the installation cavity of the processing box 101 by bolts. The serpentine tube 1082 is welded to the rectangular plate 1081. The inner end of the serpentine tube 1082 in the processing box 101 has a plurality of bent special-shaped parts to facilitate extending the circulation time of cold water inside it. The filter assembly is used for exhaust gas filtration treatment.

[0023] Secondly, one side of the short tube of the serpentine tube 1082 is the water inlet side, and the long tube side is the water outlet side. The flange arranged on the water inlet side is connected to the water outlet pipe of the water pump of the external water tank through a screw and nut, and the flange arranged on the water outlet side is flange-connected to the return water pipe flange of the external water tank through a screw and nut.

[0024] Then, the fixing frame 109 is fixedly connected to the processing box 101 and is located inside the processing box 101; the matching member is arranged on the upper and lower sides of the fixing frame 109. The cross-section of the fixing frame 109 is in the shape of a square and is fixed to the inside of the processing box 101 by bolts. The matching member is used to achieve hierarchical filtration treatment of the exhaust gas.

[0025] Finally, the lower filter screen 110 is fixedly connected to the fixing frame 109 and is located at the bottom of the fixing frame 109; the upper filter screen 111 is fixedly connected to the fixing frame 109 and is located at the top of the fixing frame 109.

The diameter of the filter holes of the upper filter screen 111 is smaller than that of the lower filter screen 110, thereby forming a waste gas hierarchical filtering structure. The dust and impurities generated by the filtration of the lower filter screen 110 can directly fall into the receiving box 106, and the receiving box 106 can be pulled out for cleaning. The impurities generated by the filtration of the upper filter screen 111 will be in the area between the upper filter screen 111 and the lower filter screen 110.

During waste gas treatment, the waste gas enters the treatment box 101 through the air inlet pipe 105, then moves upward, and is hierarchically filtered through the lower filter screen 110 and the upper filter screen 111. The dust and impurities generated by the filtration of the lower filter screen 110 can directly fall into the receiving box 106, and the receiving box 106 can be pulled out for cleaning. Further, the waste gas passes through the guide plate 107 and is discharged through the exhaust pipe 104. Before the filtered waste gas is discharged, it will pass through the serpentine tube 1082. The high-temperature waste gas will exchange heat with the cold water in the serpentine tube 1082, thereby heating up the cold water. After the cold water circulates multiple times until the temperature rises to the use temperature value, the water tank drain valve can be opened for derivation and use. Thus, when performing waste gas treatment on a gas turbine power generation device, the recovery and utilization of waste heat of waste gas can be realized, and energy waste can be reduced.
