The terms "first", "second", etc. in the specification and claims and the above drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used herein are only for the purpose of describing the embodiments of the present application, and are not intended to limit the present application.

[0023] With reference to Figure 1 And Figure 2The embodiment of the present application provides a flow guide heat exchange purifier, which comprises a support frame 1, a plurality of hot side heat exchange channels 2 and a plurality of cold side heat exchange channels 3 arranged along the height direction of the support frame 1, a hot side filtering air inlet structure 4 arranged at one end of the hot side heat exchange channel 2, a cold side filtering air inlet structure 5 arranged at one end of the cold side heat exchange channel 3, and the hot side filtering air inlet structure 4 abutting one side of the cold side filtering air inlet structure 5. When the flow guide heat exchange purifier is in operation, the tail exhaust gas enters the hot side heat exchange channel 2 through the hot side filtering air inlet structure 4, and the natural wind enters the cold side heat exchange channel 3 through the cold side filtering air inlet structure 5, and the tail exhaust gas and the natural wind are subjected to heat exchange in the corresponding heat exchange channels.

[0024] Specifically, the support frame 1 comprises an inner frame body and an outer frame body, the inner frame body is used for mounting the hot side heat exchange channel 2 and the cold side heat exchange channel 3, and the outer frame body is used for mounting the hot side filtering air inlet structure 4 and the cold side filtering air inlet structure 5. In order to ensure the heat exchange efficiency, the plurality of hot side heat exchange channels 2 and the plurality of cold side heat exchange channels 3 are arranged alternately, that is, the hot side heat exchange channel 2 is adjacent to the cold side heat exchange channel 3, and the cold side heat exchange channel 3 is adjacent to the hot side heat exchange channel 2. The hot side heat exchange channel 2 comprises a plurality of hot side sub heat exchange channels 21 separated from each other, the cold side heat exchange channel 3 comprises a plurality of cold side sub heat exchange channels 31 separated from each other, and the plurality of hot side heat exchange channels 2 and the plurality of cold side heat exchange channels 3 are uniformly arranged along the height direction of the support frame 1. By arranging the hot side heat exchange channel 2 and the cold side heat exchange channel 3 in this way, the heat exchange area of the tail exhaust gas and the natural wind can be effectively increased, so that the heat exchange efficiency is ensured.

[0025] The hot side filtering air inlet structure 4 and the cold side filtering air inlet structure 5 are used for filtering and guiding the tail exhaust gas and the natural wind. Specifically, the hot side filtering air inlet structure 4 comprises a hot side air inlet channel 41 and a hot side filter 42 arranged in the hot side air inlet channel 41, the cold side filtering air inlet structure 5 comprises a cold side air inlet channel 51 and a cold side filter 52 arranged in the cold side air inlet channel 51, in the embodiment, the structure of the cold side air inlet channel 51 is the same as that of the hot side air inlet channel 41, and the axis of the cold side air inlet channel 51 is perpendicular to the axis of the hot side air inlet channel 41.

[0026] Taking the hot side filter air inlet structure 4 as an example, the hot side air inlet channel 41 has a hot side air inlet 411 and a hot side air outlet 412, the hot side air outlet 412 is communicated with the hot side heat exchange channel 2, the hot side filter 42 is arranged at the hot side air inlet 411, and the hot side filter 42 comprises a primary filter and a medium filter. The hot side air inlet 411 and the hot side air outlet 412 are connected with a hot side buffer portion 413, in order to ensure the air inlet amount and the heat exchange efficiency, the size of the hot side buffer portion 413 gradually decreases from one side of the hot side air inlet 411 to one side of the hot side air outlet 412, that is, the larger side of the hot side buffer portion 413 is the hot side air inlet 411, and the smaller side of the hot side buffer portion 413 is the hot side air outlet 412, so that the hot side air inlet 411 can have a larger air inlet area to allow more gas to enter, and the gas entering the hot side air inlet 411 accelerates and flows under the action of the hot side buffer portion 413 and is gathered to the hot side air outlet 412 to enter the hot side heat exchange channel 2.

[0027] With reference to Figure 1 , Figure 2 and Figure 3 , in order to ensure that the purifier structure is compact and convenient to maintain, the plurality of hot side air inlets 411 are close to each other and abut, and the plurality of hot side air inlets 411 surround to form an air inlet surface, and when the hot side filter 42 is installed, the plurality of hot side filters 42 are close to each other to form a filter surface with a larger area, so that more gas can be introduced.

In the embodiment, the first limiting piece 431 is a "L" shaped baffle, the first limiting piece 431 is installed on the outer frame body in a threaded connection mode, and the first limiting piece 431 limits and abuts against the hot side filter 42, so as to limit the hot side filter 42 in the air inlet direction; the second limiting piece 432 is a baffle with a rectangular cross section, the second limiting piece 432 is installed on the outer frame body in an interference connection mode, and the second limiting piece 432 limits and abuts against the hot side filter 42, so as to limit the hot side filter 42 on the side perpendicular to the air inlet direction.

[0029] By arranging the hot side filter air inlet structure 4, the hot side filter 42 is supported and limited by the hot side connecting piece 43, when the hot side filter 42 needs to be cleaned and maintained, the hot side filter 42 can be removed from the support frame 1 by loosening the hot side connecting piece 43 to release the limitation of the hot side filter 42, so that the specific hot side filter 42 can be cleaned or maintained and replaced, thereby ensuring the convenience of purifier installation and maintenance.

[0030] The cold side filter air inlet structure 5 comprises a corresponding cold side air inlet channel 51, a cold side filter 52 and a cold side connecting piece 53. The cold side air inlet channel 51 has the same structure as the hot side air inlet channel 41, the cold side filter 52 has the same structure as the hot side filter 42, and the cold side connecting piece 53 has the same structure as the hot side connecting piece 43, which will not be described again. The cold side filter air inlet structure 5 is adjacent to the hot side filter air inlet channel, and the hot side heat exchange channel 2 and the cold side heat exchange channel 3 are located between the cold side filter air inlet structure 5 and the hot side filter air inlet channel, realizing the integration of the filtering, flow guiding and heat exchange functions, which can effectively reduce the required area of the installation occupation, and the equipment flange of the hot side heat exchange channel 2 and the cold side heat exchange channel 3 far away from the side of the corresponding air inlet structure also has a plurality of through holes and threaded holes in the circumferential direction to facilitate the installation of other structures to treat the exhaust gas.
