DETAILED DESCRIPTION
[0015] Reference Figure 1-Figure 8A modular filtering and rectifying structure, comprising: a filtering and rectifying box 1, a filter screen module 2 is detachably connected inside the filtering and rectifying box, and a rectifying module is detachably connected to the air outlet side of the filtering and rectifying box; The bottom of the filtering and rectifying box is connected to the ash discharge pipe 14; A primary inertial dust removal structure and a secondary inertial dust removal structure are fixed in the filter rectifier box. The filter rectifier box is placed on a fixed bracket 3. A filter screen socket 11 is provided on the filter rectifier box. The filter screen module is inserted into the filter rectifier box through the filter screen socket. A rectifier socket 12 is provided near the air outlet side. The rectifier module is inserted into the filter rectifier box through the rectifier socket. The outlet of the filter rectifier box is connected to the inlet of the fan, and an ash bucket is placed at the open bottom of the ash discharge pipe at the bottom of the filter rectifier box. The operation of the equipment mainly realizes filtering and rectification through the air duct structure, in which the flow pressure head is provided by the external fan, and the external fan is turned off when the module needs to be replaced; when replacing the filter module, the filter module is pulled out by turning the filter handle, and the detachable filter is replaced and then inserted back into the filter rectifier box; when it is necessary to adjust the intake preheating or precooling, the rectifier handle is turned out to pull out the rectifier module and replace it with an electric heating or semiconductor refrigeration module; The primary inertial dust removal structure is a side wall block 13, and the obtuse diversion surface of the side wall block faces the air inlet 5 of the filter rectifier box; The secondary inertial dust removal structure is a baffle 15 protruding from the top of the filter rectifier box on the air outlet side close to the filter rectifier box; The air duct system takes in air from the front end of the filter rectifier box, passes through the first-level inertial dust removal structure, and filters the dust-free air A from the upper end. The dust-rich air B hits the side wall block through inertia. Due to the pressure of the outlet fan, the air B is effectively filtered through the filter module. Then the air A and the air B converge and pass through the second-level inertial dust removal structure, and then are discharged from the filter rectifier box through the rectifier module. Part of the gas that enters the ash discharge pipe flows back to the filter rectifier box through the ash discharge pipe. The baffle is arranged vertically downward.
[0016] The ash discharge pipe is a V-shaped pipe with an open bottom.
[0017] Reference Figure 3 The filter module includes a detachable filter 21, and a filter handle 22 is hinged on the side of the detachable filter.
[0018] Reference Figure 4 The rectifier module includes a rectifier plate 41, and a rectifier handle 42 is hinged on the side of the rectifier plate.
[0019] An ash separator 17 is fixed in the filter rectifier box, and the lower part of the ash separator is inserted into the ash discharge pipe. The upper side surface of the ash separator and the vertical surface of the side wall block are respectively provided with an inlay 16 for inserting the edge of the filter module. After the filter module is inserted, an air filter channel 19 is formed through the side wall block, the filter module and the ash separator.
[0020] Reference Fig. 9 The dust system enters the first-level inertial dust removal structure with the intake air. The dust hits the side wall block, and the large particles fall on the slope surface 18 at the bottom of the filter rectifier box. Due to the action of gravity, the dust falls on the bottom ash discharge pipe; the intake air B enters the filter air channel. Due to the pressure of the outlet fan, part of the intake air B will pass through the filter module, and the dust is filtered out by the filter module. Then the intake air A and the intake air B converge and pass through the second-level inertial dust removal structure, and are thrown on the rear slope surface of the filter rectifier box and fall into the ash discharge pipe. Finally, the dust is concentrated in the ash discharge pipe and discharged into the bottom ash bucket.
