In some embodiments, the vent valve 32 may include a first valve disposed at the inlet of the vent passage 12 and a second valve disposed at the outlet of the vent passage, with the two valves providing improved sealing. In addition, in the purification mode, the first valve and the second valve are closed, and clean positive pressure gas can be introduced into the ventilation channel 12 between the first valve and the second valve, so that the pressure of the ventilation channel 12 between the first valve and the second valve is greater than that of the purification channel, and the first valve can be prevented from leaking polluted gas into the ventilation channel 12. In addition, in the cleaning mode, the first valve and the second valve are closed, and a negative pressure pipeline is applied to the ventilation channel 12 between the first valve and the second valve, so that the pressure of the ventilation channel 12 between the first valve and the second valve is smaller than that of the cleaning channel, and the polluted gas leaked from the first valve into the ventilation channel 12 can be discharged from the negative pressure pipeline.
The inventor finds that: if adopt the binary channels structure to realize ventilation, purification performance, under realizing the purification mode, close the ventilation valve, open the purge valve, because adopt same purification fan to the inlet side of ventilation passageway and the entry side-blowing of purge channel, if the ventilation valve is sealed not tight, lead to unpurified contaminated gas to be discharged by purge channel easily, cause dangerous accident.
Fig. 1 to 11 show an embodiment of a dual-channel air ventilation and purification device and an air purification method thereof according to the present invention, based on the ventilation and purification device in the above embodiment, referring to fig. 1 to 11, a dual-channel air ventilation and purification device according to an embodiment of the present invention includes:
decontaminating member 10, comprising: the device comprises a ventilation channel 12 and a purification channel 11 which are arranged in parallel, wherein the ventilation channel 12 is provided with a ventilation valve 32, the purification channel 11 is provided with a purification valve 31, and an outlet of the ventilation channel 12 is communicated with an outlet of the purification channel 11;
a purge fan 20, an air outlet side of the purge fan 20 being open to an inlet side of the ventilation passage 12 and an inlet side of the purge passage 11;
the channel pressure adjusting device is used for exhausting air to the ventilation channel 12 in the purification part 10 of the two-channel air ventilation and purification device, so that the air pressure inside the purification channel 11 is larger than the air pressure inside the ventilation channel 12.
In the technical solution provided in the embodiment of the present invention, in the purification mode, under the condition that the ventilation valve 32 is closed, the purification valve 31 is opened, and the same purification fan 20 is used to blow air to the inlet side of the ventilation channel 12 and the inlet side of the purification channel 11, the ventilation channel 12 in the purification component 10 of the dual-channel air ventilation purification device is pumped so that the air pressure inside the purification channel 11 is greater than the air pressure inside the ventilation channel 12, compared with the prior art, if the ventilation valve 32 is not tightly sealed, the polluted gas leaked into the ventilation channel 12 by the ventilation valve 32 will be pumped by the channel pressure adjustment device because the air pressure inside the purification channel 11 is greater than the air pressure inside the ventilation channel 12, and will not be discharged from the unified outlet communicating with the outlet of the ventilation channel 12 and the outlet of the purification channel 11, thereby improving the safety of the use of the purification mode.
Wherein the vent valve 32 may be arranged at an inlet position of the vent channel 12, said vent valve 32 comprising a first valve of the inlet of the vent channel 12. The channel pressure adjusting device is used for pumping air between the inlet of the ventilation channel 12 and the outlet of the ventilation channel 12 in the two-channel air ventilation and purification device purification part 10, and the polluted air leaked into the ventilation channel 12 from the ventilation valve 32 at the inlet of the ventilation channel 12 can be pumped away by the channel pressure adjusting device. Since the outlet of the ventilation channel 12 is communicated with the outlet of the purge channel 11, a part of the clean air discharged from the outlet of the purge channel 11 is drawn by the channel pressure adjusting device, resulting in a large loss of air flow. Further, in order to improve the utilization rate of the clean air discharged from the outlet of the purge passage 11, the vent valve 32 may be disposed at an inlet position and an outlet position of the vent passage 12, and the vent valve 32 includes a first valve at the inlet of the vent passage 12 and a second valve at the outlet of the vent passage 12. The channel pressure adjusting device is used for pumping air between the inlet of the ventilation channel 12 and the outlet of the ventilation channel 12 in the two-channel air ventilation and purification device purification part 10, and the polluted air leaked into the ventilation channel 12 from the ventilation valve 32 at the inlet of the ventilation channel 12 can be pumped away by the channel pressure adjusting device. Because the outlet of the ventilation channel 12 is provided with the second valve, the second valve can be closed in the purification mode, so that the air quantity of the clean air discharged from the outlet of the purification channel 11 entering the ventilation channel 12 can be greatly reduced (the second valve leaks to enter a trace amount of clean air in the ventilation channel 12).
