Device for purifying gas by using liquid medium

The technical field is as follows:

the utility model relates to a gaseous purification field especially relates to utilize purifier of liquid medium purified gas.

Background art:

the development of modern industry brings great convenience to human life, and meanwhile, harmful substances such as vehicle exhaust gas, nitrogen oxides, sulfur oxides, restaurant oil smoke, SARA virus, PM2.5, PM10 and the like come along, so that air pollution seriously harms the living environment of human beings. The haze brings great threat to the health of the respiratory system of human beings, and seriously harms the health of people. In order to create a clean working environment and non-polluted air, various air purification devices have been developed.

In order to achieve a good purifying effect, the conventional air purifying device and equipment usually adopt a high-density filtering material for gas filtration. However, the high density of the filter material may result in the obstruction of the ventilation effect, and the filter material may be too sparse, resulting in the reduction of the purification effect. In order to ensure the air filtration quality, the traditional air purification device and equipment need to frequently replace filter materials such as filter elements and the like, and the use cost is very high.

The liquid medium is used for purifying gas, so that the air purifier is supplemented and perfected for the traditional air purifying equipment, has the function which cannot be realized by the traditional air purifier in the aspects of comprehensive dust removal, disinfection and sterilization and the like, and makes up the defects of the traditional air purifier. The liquid medium is used for purifying the gas, a filter element and a filter screen are not needed, and the use cost is very low.

Therefore, the urgent need is for a device for purifying gas by using liquid medium, which satisfies different purification requirements of different spaces to gas, and achieves the purpose of pertinently taking different purification measures to different gas pollutions.

The utility model has the following contents:

an object of the utility model is to provide an use liquid medium to purify the gas's device, use the liquid medium of different compositions to carry out corresponding purification to the air, compensate the defect of traditional air purification device and equipment.

According to one aspect of the present invention, the above object is achieved by providing an apparatus for purifying gas using a liquid medium, the apparatus comprising a tubular gas passage, a liquid medium emitting device, a gas pressurizing and depressurizing device disposed on one side or both sides of a flow of the liquid medium,

the liquid medium emitting device comprises a liquid medium ejector and a pipeline or a liquid medium pump for conveying a liquid medium for the liquid medium ejector, the liquid medium ejector comprises but is not limited to a spray head and a spray nozzle, the liquid medium emitting device is installed and arranged on the inner wall of the tubular gas channel, the liquid medium emitting device emits single or multiple liquid medium flows into the tubular gas channel according to needs, the liquid medium flows block or block gas flowing through the tubular gas channel, the gas flows from a high gas pressure place to a low gas pressure place under the action of gas pressure difference, and the gas in the tubular gas channel flows through a gap between the liquid medium flows and the wall of the tubular gas channel.

In another preferred embodiment; the tubular gas channel is a hollow pipeline type receiving main body, the basic constituent element of the tubular gas channel is a tubular gas channel unit, and the tubular gas channel is formed by a single tubular gas channel unit, a plurality of tubular gas channel units or formed by arranging and combining one or more groups of tubular gas channel units.

In another preferred embodiment: the gas pressure increasing and reducing device can change the gas pressure on two sides of the liquid medium flow in the tubular gas passage, and comprises but not limited to a fan, a blower and a gas pump.

According to the specific requirement of purifying gas, the liquid medium can be added with the required components of sterilization, degerming, water purification and the like, so that pollutants in the liquid medium can be decomposed and adsorbed in a targeted manner, and toxic bacteria and viruses in the liquid medium can be killed.

Description of the drawings:

fig. 1 shows the basic structural unit of the present invention.

Fig. 2 is a schematic structural diagram of an embodiment of the present invention.

The specific implementation mode is as follows:

the traditional air purification method which is generally adopted at present has certain defects and shortcomings, and the solid-state filter screen filtering method has limited filtering efficiency of filtering particulate pollutants by using a filter element and a filter screen. After the filter element works for a period of time, the filtering efficiency of the filter element is obviously reduced, dust is separated from the solid filter screen and blown out, and the possibility of secondary pollution is caused. The traditional filter screen and filter element filtering method is not suitable for source decontamination of pollution sources (pre-decontamination treatment of factory and enterprise waste gas). In order to maintain the efficiency of decontamination, conventional gas filtration facilities using screens require replacement of the screen, filter cartridge or cleaning at intervals, which is a costly and cumbersome task.

Therefore, the present invention has been made in view of the above problems. The gas flows from the high-pressure end to the low-pressure end under the action of the air pressure difference, and flows through the liquid medium flow or the gap between the liquid medium flow and the wall of the tubular gas channel, so that the gas filtering efficiency is ensured, the gas purification quality is also ensured, and the aims of dust removal, purification, disinfection and sterilization are fulfilled.
