Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

Example (b):

referring to fig. 1, the present embodiment provides a building ventilation air purification system, including an air inlet pipe 1 and a return air pipe 2, wherein the air inlet pipe 1 is provided with a plurality of air outlet branch pipes 11, the return air pipe 2 is provided with a plurality of return air branch pipes 21, an air inlet end of the air inlet pipe 1 is connected with a purification pipe 3 with a purification assembly inside, and the purification pipe 3 is provided with a heat exchange assembly; the air outlet end of the return air pipe 2 is communicated with the air inlet end of the heat exchange assembly.

Specifically, as shown in fig. 2 and 3, the purification assembly includes an ultraviolet lamp 32 fixedly installed in the purification tube 3 through a connecting rod 31 and coaxially installed with the purification tube 3, and a plurality of negative ion generators 33 installed on the inner sidewall of the front end of the purification tube 3. Therefore, when the ultraviolet lamp tube 32 works, the air flowing through the purifying tube 3 can be sterilized and disinfected, and meanwhile, the negative ion generator 33 can generate negative ions, and finally the negative ions can be led into a room along with the air to purify the air.

Referring to fig. 3 and 4, the heat exchange assembly includes a heat insulating sleeve 41 fixedly sleeved outside the purification tube 3, and a helical blade 42 fixedly installed between the purification tube 3 and the heat insulating sleeve 41 to form a helical channel; the front end of the heat insulation sleeve 41 is communicated with the air outlet end of the return air pipe 2; the end of the heat insulating sleeve 41 is communicated with an air guide pipe 43. The spiral blades 42 are arranged to form a spiral channel to increase the flowing distance of air in the heat insulating sleeve, so that the flowing time of air in the heat insulating sleeve 41 is increased, thereby improving the heat exchange efficiency.

As shown in fig. 5, in order to prevent outdoor dust from being introduced into the room, a filter pipe 5 having a filter assembly therein is further connected to the end of the purification pipe 3, and the filter assembly includes a dust filter 51 and a HEPA filter 52 fixedly installed in the filter pipe 5 in this order.

The implementation principle is as follows: when the ventilation system works, outside air is guided into the air inlet pipe 1 through the filter pipe 5 and the purification pipe 3 and then is guided into a room through the air outlet branch pipe 11, and indoor air is guided into the air return pipe 2 through the air return branch pipe 21 and finally is guided into the outside through the air return pipe 2.

In winter, the indoor air is heated, so the indoor air temperature is high, the outdoor air temperature is low, therefore, during ventilation, the external cold air is guided into the purifying pipe 3 and finally into the indoor, meanwhile, the indoor hot air is guided into the heat insulation sleeve 41 through the air return pipe 2, and the hot air flows along the spiral channel formed by the spiral blades 42 in the heat insulation sleeve 41 and finally flows into the outdoor; in the above-mentioned process, the hot-air that flows into in the thermal-insulated cover can be through the pipe wall of purge tube 3 with heat transfer to in the purge tube 3 to the realization realizes the heat exchange with the cold air in the purge tube 3, for the cold air intensification in the purge tube 3, the cold air after finally rising the temperature just can be leading-in indoor, so just make full use of the resource.
