Detailed Description

The following description of the preferred embodiments of the present invention will be made in conjunction with the accompanying drawings 1-2, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be more clearly and clearly defined.

In order to purify the waste gas of the operating room efficiently and reduce the possibility of cross contamination of hospitals and the influence on the external environment, the embodiment discloses a waste gas treatment device for purifying the operating room, wherein an air inlet pipeline 2 and an air outlet pipeline 3 communicated with the inside of a cabinet body 1 are respectively arranged at two ends of the top of the cabinet body 1, a high-voltage electrostatic dust collector 4, a high-efficiency filter 5, a rapid heating dryer 6 and an ultraviolet sterilization lamp 7 are sequentially arranged from one side of the air inlet pipeline 2 to one side of the air outlet pipeline 3 in the cabinet body 1, an exhaust fan 8 is arranged in the air outlet pipeline 3, an electric switch valve 9 is arranged in the air outlet pipeline 3 and positioned at the inner side of the exhaust fan 8, the high-efficiency filter 5 is connected with a differential pressure switch 11 and can feed back a filter blocking signal, and a power supply.

The power control cabinet comprises a start control key, a stop control key and a pause maintenance control key which are respectively electrically connected with an electric control device in the waste gas treatment device, the state of a filter corresponding to a pressure difference signal reacted by the pressure difference switch 11 is reflected on a three-color indicator lamp on the power control cabinet, and a maintainer can conveniently monitor the working state of the filter at any time so as to timely deal with abnormal states.

One side that is close to exhaust duct 3 in the cabinet body 1 is equipped with measurement module 10, and measurement module 10 collects measuring instrument and electric switch valve controller in an organic whole, and the measuring instrument mainly is the instrument of dust particulate matter content and organic matter content in the detection gas, electric switch valve controller and electric switch valve 9 electric connection.

The high efficiency filter 5 is detachably fixed inside the cabinet 1 through the filter screen bracket 12, and the set position is detected to be beneficial to the exertion of the filtering efficiency to the maximum.

The position that corresponds with high efficiency filter 5 on 1 chamber door of the cabinet body is equipped with the access door 13 that can open, makes things convenient for maintenance personal to get into the internal portion of cabinet and overhauls or change the filter, is equipped with the lock on access door 13 in order to prevent that other people from missing to go into or bring other inconveniences.

The specific operation process is as follows:

firstly, when the air in the cabinet body 1 is detected and confirmed by the measuring module 10 to meet the emission requirement, the electric switch valve 9 is in an open state, the exhaust fan 8 normally operates, the interior of the cabinet body 1 is in a negative pressure state, so that the waste gas in the operating room smoothly enters the cabinet body 1 through the air inlet pipeline 2, the waste gas entering the cabinet body 1 firstly passes through the high-voltage electrostatic dust collector 4, and after the process, nearly 95% of dust particles in the air and germs attached to the surfaces of the dust particles can be removed; then in the process of passing through the high-efficiency filter 5, dust particles in the gas can be further removed, the high-efficiency filter 5 is connected with a pressure difference switch 11 and serves as a feedback device of a filter blockage signal, the working condition of the filter can be fed back in time, the working state of the unit can be determined by observing a three-color indicator lamp on a power supply control cabinet, and the unit indicator lamp gives an alarm and can be overhauled or replaced in time when needing to be overhauled or replaced; the gas passes through the rapid heating dryer 6 in sequence, so that the humidity in the waste gas is reduced, the environment where bacteria grow is damaged, and redundant organic matters in the air are eliminated; finally, the gas is discharged from the exhaust pipeline 3 after being sterilized by the ultraviolet sterilizing lamp 7.

In addition, because the measuring module 10 is arranged on one side of the exhaust duct 3, the measuring instrument contained in the measuring module can detect the dust content, the organic matter content and the like in the processed gas, if the content is lower than the preset detection limit, the gas is normally discharged, and if the content is higher than the preset detection limit, the electric switch valve controller works to control the electric switch valve 9 to be closed, the exhaust fan 8 stops working until the air in the cabinet body 1 reaches the emission standard again, and if the air in the cabinet body does not reach the emission standard all the time, the whole machine can be stopped for maintenance.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
