Description

Technical Field

[0001] The present invention relates to the technical field of air purification, and specifically to an indoor ventilation and air purification circulation system for operating rooms. Background Art

[0002] As a key place for performing surgical operations, the operating room has extremely high requirements for air quality. Pollutants such as dust particles and microorganisms in the air may cause surgical incision infections, seriously affect the postoperative recovery of patients, and even endanger lives.

[0003] Existing operating room ventilation and air purification systems have many deficiencies in practical applications. The filtration efficiency of some purification equipment for fine particles and microorganisms is poor, making it difficult to meet the purification standards of high-grade operating rooms; moreover, the system ventilation design is unreasonable, resulting in disordered indoor air flow organization, ventilation dead corners, and pollutant accumulation. Therefore, in order to solve the above problems, an indoor ventilation and air purification circulation system for operating rooms is proposed. Summary of the Invention

[0004] In order to make up for the deficiencies of the existing technology, the present invention proposes an indoor ventilation and air purification circulation system for operating rooms.

[0005] An indoor ventilation and air purification circulation system for operating rooms includes: S1 fresh air introduction module;

[0006] S2 primary filtration module;

[0007] S3 secondary filtration module;

[0008] S4 terminal filtration module;

[0009] S5 disinfection module;

[0010] S6 inspection module;

[0011] S7 air supply module;

[0012] S8 air outlet module;

[0013] S9 discharge module;

[0014] The S1 fresh air introduction module includes: a fresh air inlet and an electric air valve arranged inside the fresh air inlet, a rain-proof louver and an insect-proof net arranged outside the fresh air inlet. The S1 fresh air introduction module is responsible for introducing fresh air from the outside and providing sufficient fresh air volume for the operating room.

[0015] Preferably, the S2 primary filtration module includes: a primary filter. The primary filter uses a fibrous filter material, and the fibers are intertwined to form numerous small pores. When air flows through, pollutants with larger particle sizes will be blocked by the fibers and adsorbed on the surface of the filter material due to inertial collision, interception, etc., thus separating from the air and achieving the preliminary purification of the air.

[0016] Preferably, the S3 secondary filtration module includes: a medium - efficiency filter. The medium - efficiency filter uses a synthetic fiber material filter element; when the dusty air passes through the medium - efficiency filter, dust particles will deviate from the air flow direction due to inertia, collide with the synthetic fibers and be captured; smaller dust particles will diffuse to the surface of the synthetic fibers due to Brownian motion and be adsorbed and retained, achieving the secondary purification of the air.

[0017] Preferably, the S4 terminal filtration module includes: a high - efficiency filter. The high - efficiency filter element uses glass fiber filter paper; when the particulate pollutants in the air pass through the high - efficiency filter with the air flow, some particles with particle sizes similar to the fiber spacing will be directly blocked and intercepted by the fibers and cannot pass through the filter, thus separating from the air and achieving the terminal purification of the air.

[0018] Preferably, the S5 disinfection and sterilization module includes a reaction chamber, an ultraviolet sterilizer, and a plasma sterilizer; the reaction chamber provides space for the disinfection and sterilization reaction, ensuring that the fresh air has sufficient residence time in it to fully carry out the disinfection and sterilization process; when the fresh air passes through the reaction chamber equipped with an ultraviolet sterilizer and a plasma sterilizer, the ultraviolet rays will irradiate the air in all directions, killing bacteria and viruses in it. A large number of active particles react with microorganisms such as bacteria and viruses, destroying their cell walls and cell membranes, causing the leakage of intracellular substances, and leading to the death of microorganisms, thus completing the disinfection and sterilization of the air.

[0019] Preferably, the S6 inspection module includes a dust particle counter, an air volume sensor, and an air quality sensor. By using the dust particle counter to monitor the quantity and size of dust particles in the air in real - time, it can accurately understand the pollution status of suspended particulate matter in the air. By detecting the air volume through the air volume sensor, it can accurately control the air flow input into the operating room subsequently. By using the air quality sensor to monitor various parameters in the air of the operating room in real - time, such as dust particle concentration, microorganism content, concentrations of harmful gases (such as formaldehyde, ozone, etc.), temperature and humidity, it can accurately reflect the air quality status.

[0020] Preferably, the S7 air supply module includes: a plurality of high - efficiency air inlets are arranged at the position of the operating room ceiling close to the operating table. The air inlets adopt a unique streamline structure, which can make the fresh air enter the operating room in a uniform and gentle manner, avoid the formation of air flow dead - ends, and reduce the accumulation of dust.

[0021] Preferably, the S8 air outlet module includes: a plurality of air outlets are arranged around the operating room floor, and the plurality of air outlets are connected to the S2 primary filtration module, and the internal air of the operating room is discharged through the plurality of air outlets.

[0022] Preferably, the S9 discharge module: includes a discharge pipe and a control valve, and the on-off of the discharge pipe is controlled by the control valve, so that the air output by the S8 air outlet module is discharged through the discharge pipe.

[0023] The advantages of the present invention are as follows:

[0024] Through the multi-stage composite filtration structure and advanced sterilization technology, the present invention can effectively remove various pollutants in the air, significantly improve the air quality of the operating room, reduce the risk of surgical infection. At the same time, a unique air flow organization design is also adopted to eliminate ventilation dead corners, ensure the full circulation of indoor air, and provide a stable air environment for the operation.
