Hospital department exhaust treatment device and method

Abstract

The invention discloses a hospital department exhaust treatment device and method. The treatment device comprises a primary filtering unit, a sterilizing and disinfecting unit, a secondary filtering unit and an ultraviolet sterilizing and disinfecting unit. An electrostatic dust collector is adopted in the primary filtering unit, and an air inlet of the electrostatic dust collector communicates with an exhaust outlet of the hospital department. The primary filtering unit comprises two particle activated carbon adsorption recycling devices which are connected in parallel, and when one of the particle activated carbon adsorption recycling devices is in a working state, the other particle activated carbon adsorption recycling device is in a standby state. Air inlets of the particle activatedcarbon adsorption recycling devices communicate with an exhaust pipe at the top of a tower body. An air inlet of the ultraviolet sterilizing and disinfecting unit communicates with air outlets of theparticle activated carbon adsorption recycling devices. According to the hospital department exhaust treatment device and method, the structure is reasonable, and treatment of exhausting of differentdepartments is achieved.

Description

technical field [0001] The invention relates to the technical field of hospital equipment, in particular to a hospital department exhaust air processing device and processing method. Background technique [0002] The hospital is a place where patients gather. Because there are many patients in the hospital, various pollutant gases will be produced, especially for patients with infectious diseases. It is easy to cause a large-scale spread of diseases and endanger public safety. Therefore, in each department of the hospital, it is necessary to set up an exhaust system to regularly exhaust the air to the outside and introduce fresh air to improve the quality of the air in the department. However, the discharged outdoor air will contain a large amount of infectious bacteria and infectious viruses produced by the patient's breath, which is also a kind of pollution to the outdoor air. This will also cause varying degrees of disturbance and impact on residents living around the h...

Problems solved by technology

That is, the spraying method is used for sterilization and disinfection, but in this way, the contact area between the reaction reagent and the exhaust gas is small, the sterilization is not sufficient, and the sterilization effect needs to be improved; the exhaust gas flow passes through the airflow in the distribution plate installed inside the reactor 4 The channel rises directly and has no demisting effect. There is a phenomenon that the exhaust gas is directly discharged into the atmosphere with the air flow, and the treatment effect is not particularly good; moreover, the system uses a sterilization procedure, so that the sterilization effect needs to be further improved
