Construction air exchange device

Abstract

The invention discloses a construction air exchange device. The device comprises a machine shell, wherein an air blowing mechanism is arranged in the middle of an inner cavity of the machine shell, awet curtain is arranged on one side of the air blowing mechanism, a water spraying cover is arranged at the top end of the wet curtain, a plurality of nozzles are fixedly inserted and connected in thebottom end of the water spraying cover, one side of the water spraying cover is in fixed communication with a water pump through a guide pipe, the bottom end of the wet curtain is provided with a water receiving cover, the bottom end of the water receiving cover is fixedly connected with a water outlet pipe, the inner wall of the water receiving cover is fixedly connected with a strip-shaped bearing plate, and the top end of the strip-shaped bearing plate is provided with a filter screen. According to the device, the arrangement of the wet curtain, the water pump, the water spraying cover andthe nozzles are utilized, and in combination with the use of the air blowing mechanism, air blown into a workshop can be filtered and cooled by the wet curtain in advance, particles of dust and the like in the air are removed, and the temperature of the air is reduced, so that the freshness degree of the exchanged air in the workshop is improved; and meanwhile, the water receiving cover, the water outlet pipe and the filter screen are cooperatively used to filter and recover sewage generated after the wet curtain is cleaned, and thus the recovery utilization rate of water resources is increased.

Description

technical field [0001] The invention relates to the field of air exchange devices, in particular to a construction air exchange device. Background technique [0002] At present, in some processing workshops, especially some wood processing workshops, due to the debris generated during processing and the heat energy generated by electrical equipment during the processing, the air in the workshop will be mixed with a lot of floating debris, causing The pollution of the workshop environment, the staff in this environment for a long time will easily affect their health, and at the same time, the heat generated by the electrical equipment will be transferred to the air, which will increase the air temperature and reduce the comfort of the staff when working in the workshop. Therefore, many Air exchange devices will be installed in the workshop to discharge the dirty and hot air in the workshop. [0003] Most of the air exchange devices used today use fans to blow the outside air...

[0002] At present, in some processing workshops, especially some wood processing workshops, due to the debris generated during processing and the heat energy generated by electrical equipment during the processing, the air in the workshop will be mixed with a lot of floating debris, causing The pollution of the workshop environment, the staff in this environment for a long time will easily affect their health, and at the same time, the heat generated by the electrical equipment will be transferred to the air, which will increase the air temperature and reduce the comfort of the staff when working in the workshop. Therefore, many Air exchange devices will be installed in the workshop to discharge the dirty and hot air in the workshop

[0003] Most of the air exchange devices used today use fans to blow the outside air into the workshop, so that the gas in the workshop is blown out from the exhaust pipe by using the pressure relationship to achieve a ventilation effect, but this directly blows the outside The way of blowing air into the workshop to squeeze out the air in the workshop is simply to achieve an air replacement. The dust mixed in the external air will still be brought into the workshop, and the temperature of the external air is similar to the outdoor temperature, thus Resulting in reduced air quality blown into the workshop
