Description

Infectious disease ward air purification device

technical field

The utility model relates to a gas disinfection equipment among medical instruments, in particular to an air purification device for an infectious disease ward.

Background technique

The gas exhaled by patients with infectious diseases often contains pathogens and is highly infectious. In addition to the gas exhaled in the ward, some seriously ill patients cannot get out of bed and often defecate and urinate indoors. Patients eat and live in the ward. The air inside is turbid, which is not conducive to the recovery of patients. The current solution is to open windows to ventilate, and use chemical disinfectant to spray, wipe the ground and indoor utensils with poison. It can kill some germs and viruses, but is ineffective against germ spores; some are irradiated with ultraviolet light for disinfection, because patients cannot go outside the ward, and the irradiation time cannot be too long, which affects the disinfection effect.

It is characterized in that an ozone generator is fixed on the upper part of the vertical box, an ellipsoidal air purification and disinfection chamber is fixed on the middle of the vertical box, and a circulating spray cooling mechanism is fixed on the bottom of the vertical box. The inner exhaust fan is fixed on the top wall of the body, the air supply pipe of the inner exhaust fan is inserted into the ozone generator, the ozone nozzle of the ozone generator is inserted into the upper part of the elliptical air purification and disinfection chamber, and the atomization of the circulating spray cooling mechanism The nozzle is also inserted into the upper part of the elliptical air purification and disinfection chamber, and the purified air outlet is set at the lower part of the bottom front panel in the vertical box body, and the purified air exhaust fan is fixed on the inner side of the purified air outlet, and the ellipsoidal air An exhaust pipe is arranged at the bottom of the purification and disinfection chamber, and the exhaust pipe is connected with the box body of the purified air exhaust fan. The utility model is also implemented through the following measures: a drying chamber is set on the air supply pipe from the inner exhaust fan to the ozone generator to increase the production of ozone, and a filter screen cover is set on the indoor polluted air inlet to prevent larger Dust particles are sucked into the ozone generator; the circulating spray cooling mechanism is composed of a sealed water tank, a micro circulation pump, a return pipe, an atomizing nozzle, and a conduit. The sealed water tank is fixed on the bottom of the vertical box, and the ellipsoidal air The purification and disinfection chamber is connected with the sealed water tank through a conduit, so that the sewage in the ellipsoidal air purification and disinfection chamber enters the sealed water tank. The micro circulation pump is connected to the ellipsoidal air purification and disinfection chamber through the return pipe and atomizing nozzle, and the micro circulation pump Circulating backflow, the sprayed water mist can cool the produced ozone, prolong the ozone degradation time and disinfection time, and also increase the humidity of the dirty air entering the ellipsoidal air purification and disinfection chamber. The relative humidity of ozone is greater than When the temperature is 70%, the sterilization effect is the best; an umbrella-shaped waterproof cover is also provided on the exhaust pipe at the lower part of the ellipsoidal air purification and disinfection chamber; the drying chamber is composed of a chamber body and a heating pipe, and the air is dried through the heating pipe , this is the prior art, so it will not be described again; the ozone generator and circuit connection are known technologies, so it will not be described more.

The beneficial effect of the utility model is that: compared with the current device for purifying and disinfecting air by the ozone generator, since a drying chamber is added on the pipeline where the air enters the ozone generator, the dried air can make the ozone concentration high and sterilize the air. Powerful; because there is a spray cooling mechanism in the ellipsoidal air purification and disinfection chamber, the production of ozone is maintained at high stability, and at the same time, the humidity in the ellipsoidal air purification and disinfection chamber is increased to enhance the disinfection effect, so it is especially suitable for infectious diseases Air purification in wards.
