The ozone produced by the action of high-voltage electrostatic discharge is dissolved in the water curtain to kill bacteria and viruses.

Description

一种水媒绿色空气病菌病毒清除机Water-borne green air germ virus removal machine 技术领域Technical field

本发明涉及一种水媒绿色空气病菌病毒清除机。The invention relates to a water-borne green air germ virus removal machine.

背景技术Background technique

现有医院室内清除细菌和病毒采用过滤设备(层流洁净技术)或采用紫外线线灯进行。层流洁净设备已广泛用于医院的无菌病房，手术室等，层流洁净技术是过滤原理，只能滤掉细菌而对病毒无效，因为病毒直径只有细菌的十分之一，层流设备的滤网网孔大于病毒直径，紫外线灯虽能杀灭病毒，但对人体有伤害性，无法实现人机共处实时消毒，所以医院里因病毒传播而感染成了一大难题。Existing hospitals use filtering equipment (laminar flow clean technology) or ultraviolet light to remove bacteria and viruses. Laminar flow cleaning equipment has been widely used in aseptic wards, operating rooms, etc. of hospitals. Laminar flow cleaning technology is the principle of filtration, which can only filter out bacteria and is ineffective against viruses, because the diameter of viruses is only one-tenth of that of bacteria. Laminar flow equipment The mesh of the filter screen is larger than the diameter of the virus. Although the ultraviolet lamp can kill the virus, it is harmful to the human body and cannot realize the real-time disinfection of the human and the machine. Therefore, the infection in the hospital due to the spread of the virus has become a major problem.

因此亟待开发出一种对空气中病菌病毒同步绿色清除机器，来解决医院室内空气病菌病毒感染传播问题。Therefore, it is urgent to develop a synchronous green cleaning machine for bacteria and viruses in the air to solve the problem of infection and transmission of indoor air bacteria and viruses in hospitals.

The invention designs a water-borne green air germ virus removal machine, which includes a box body, a discharge needle, a high-voltage electrostatic generator, and a fan. It is characterized in that there is a partitioned water curtain in the box body, and a discharge needle is arranged on one side of the water curtain. , The other side of the water curtain is equipped with a fan, one pole of the output end of the high-voltage electrostatic generator is connected to the discharge needle, the other end is grounded or connected to the water curtain, and an air inlet is set near the discharge needle on the box body, and the box body is set near the fan Air outlet. The water curtain flows out from the spray water tank arranged above the box body, the discharge needle is connected to one pole of the high-voltage electrostatic generator, the bottom of the box body below the water curtain is provided with a water tank, and a water pump is connected to the water tank and the spray water tank by a water pipe.

本发明的优点是空气净化器除了使用水之外不添加任何化学剂，利用溶解在水中的臭氧水杀灭细菌和病毒，做到了无二次污染，为一种生态型绿色空气病菌病毒清除设备。The advantage of the invention is that the air purifier does not add any chemical agent except water, uses ozone water dissolved in the water to kill bacteria and viruses, and achieves no secondary pollution.

具体实施方式Detailed ways

一种空气病菌病毒清除机，包括箱体1，放电针2，高压静电发生器3，风机4，其特征在于：在箱体内有一个分隔水幕5，在水幕的一侧设置放电针，水幕的另一侧设置风机4，高压静电发生器输出端一极接放电针，另一端接地和或水幕，在箱体邻近放电针处设置有进风口6，在箱体邻近风机处设置出风口7。水幕由设置在箱体上方的喷淋水箱8流出，水幕的下方的箱体底部设置有水槽9，有一水泵10由水管11连接水槽及喷淋水箱。An air germ virus removal machine, comprising a box body 1, a discharge needle 2, a high-voltage electrostatic generator 3, and a fan 4, and is characterized in that there is a partition water curtain 5 in the box body, and a discharge needle is arranged on one side of the water curtain. A fan 4 is set on the other side of the water curtain. One pole of the output end of the high-voltage electrostatic generator is connected to the discharge needle, and the other end is grounded and or the water curtain. An air inlet 6 is provided near the discharge needle of the cabinet, and the cabinet is adjacent to the fan. Outlet 7. The water curtain flows out from a spray water tank 8 arranged above the box body. A water tank 9 is provided at the bottom of the box body below the water curtain. A water pump 10 is connected to the water tank and the spray water tank by a water pipe 11.

本发明的基本工作过程如下，工作开机后，空气中的氧气在高压静电场放电条件下生成臭氧，臭氧随风机吸风吹向水幕，由于臭氧会溶解在水中，臭氧本身就具有较强的氧化性，会对水(本发明中灌入水箱的水采用的是普通的自来水或非纯水，含有杂质，具有导电性)中的细菌病毒产生灭杀作用。此外通过高压电场的粉尘颗粒及上面附着的细菌和病毒均会带电荷，在与水幕冲击时，被吸附到异性电荷的水幕上从而进入到水中，由于臭氧水及水幕冲刷的双重作用，本发明能高效净化空气，且能灭杀细菌病毒。此外，本发明无过滤装置，不会产生细菌病毒的积聚，不会产生二次污染。The basic working process of the present invention is as follows. After the work is turned on, the oxygen in the air generates ozone under the condition of high-voltage electrostatic field discharge, and the ozone is blown towards the water curtain with the fan suction. Since the ozone will be dissolved in the water, the ozone itself has a strong The oxidizing property of the water can kill bacteria and viruses in the water (in the present invention, the water filled into the water tank is ordinary tap water or impure water, which contains impurities and has conductivity). In addition, the dust particles passing through the high-voltage electric field and the bacteria and viruses attached to them will be charged. When they collide with the water curtain, they will be adsorbed on the water curtain of the opposite sex and enter the water due to the double effect of ozone water and water curtain washing. , The invention can efficiently purify the air, and can kill bacteria and viruses. In addition, the present invention has no filtering device, no accumulation of bacteria and viruses, and no secondary pollution.
