Description

  The present invention purifies contaminated air using groundwater stored near the surface of the contaminated soil and feeds it into the room, detoxifies used water and returns it to the contaminated soil. The present invention relates to groundwater use air and a soil cleaning device that perform cleaning and lower the water level by pumping up groundwater to prevent entry of pollutants from the site of contaminated soil to other sites.

In recent years, groundwater contamination has become a major social problem in rural areas near cities, causing health damage to residents. This phenomenon is unthinkable in the old days when clear streams used to flow through rivers. The reasons for the contamination of groundwater are the devastation of Yatsuda due to the arrangement of agricultural areas and the widespread use of chemical fertilizers and pesticides and the large consumption of electricity, water, and supplies due to improved living conditions. This contaminated groundwater is collected relatively close to the surface of the earth, and harmful chemicals and chemicals are mixed in this groundwater. In addition, since the sites are generally close to each other, contaminated groundwater in one site easily flows into the adjacent site, and contamination of the entire site proceeds. There are various means to solve this problem, but actively pumping up groundwater to purify groundwater and contaminated air, and use the temperature of groundwater (15 ℃ to 16 ℃). In the past, there has been no such thing that cleans the air at a suitable temperature with energy saving and cleans the groundwater by returning the cleaned groundwater to the surface again. In addition, although the patent document 1 and the patent document 2 are mentioned as a well-known technique relevant to this invention, it differs in this invention in a structure, the objective, and an effect.

  The contaminated air generates a large amount of negative ions by spraying and removes filth and odor by collision with water. The treated air is separated into air and water, and cooled and heated to obtain clean air having an appropriate temperature. By using groundwater as this water, it is possible to effectively use groundwater at an appropriate temperature, and the groundwater that has been pumped up and contacted with contaminated air is purified by oil-water separation, electrolysis, coagulant treatment, and the like. The soil can be cleaned by returning the cleaned groundwater to the ground surface again. In addition, groundwater pumping lowers the groundwater level of the site, preventing inflow of contaminants into other sites. In addition, since groundwater is stored at a temperature of 15 ° C to 16 ° C, heat is exchanged with the air in the steam separator using this temperature, or the air is heated to an appropriate temperature by energy saving.

To do. This treated air is separated into air and water, further separated into air and water while exchanging heat with groundwater, introduced into the duct, and discharged into the room by a fan. As a result, clean air generating a large amount of negative ions is introduced into the room. On the other hand, water in contact with contaminated air is separated from oil and water, further electrolyzed and ionized, further detoxified by chemical change using a condensing agent, ion-removed and discharged into the soil again. By this circulation, the groundwater in the soil can be purified. In addition, groundwater has a temperature of 15 ° C to 16 ° C. In winter, cleaning air is heated to an appropriate temperature by this warm water and discharged indoors. In summer, groundwater exchanges heat with hot air to lower the temperature of the air. And air of appropriate temperature can be discharged indoors. In winter, groundwater is heated and clean air with an appropriate temperature is sent indoors.

  In addition, according to claim 2 of the present invention, “groundwater use air and soil cleaning device”, since groundwater is pumped from a plurality of shallow wells and used, the contaminated soil is purified over a wide area. The site water level can be greatly reduced.

  Further, according to claim 3 of the present invention, “groundwater use air and soil cleaning device”, the application of the photocatalyst agent and the irradiation with the ozone lamp are performed in the conduit into which the cleaned air is introduced. It is possible to send air that is rich in harmless negative ions, in which bacteria in the air are sterilized and cleaned. Thereby, the room can be made a more comfortable environment.

  Further, according to claim 4 of the present invention, “groundwater use air and soil cleaning device”, the device is compactly arranged and can be conveniently used by being installed in an arbitrary place.

  Hereinafter, embodiments of the “groundwater use air and soil cleaning device” of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the “groundwater use air and soil cleaning device” of the present invention is roughly divided into an air cleaner 1, a separator for moisture separation 2, a separator 3, an oil separation tank 4, and an electrolyzer 5. , A washing water tank 6 in which groundwater is stored, a cooling / heating water tank 7, a boiler 8 for heating the cooling / heating water tank 7, a tornado mixer 9 and a coagulation tank as water detoxifying means 10 and an adsorption tank 11 and main components such as a conduit 19 for sending air into the room. Hereinafter, the above main components will be described in detail.

  The air cleaner 1 includes a spray chamber 1a, an eliminator 1b for removing water droplets, a pump 1c for discharging water (ground water) from which filth and odor of contaminated air are removed. Contaminated air is introduced into the spray chamber 1a from the introduction pipe. A conduit 16 is connected to the outlet 15 of the air cleaner 1, and the conduit 16 is connected to the separator 2 for water separation. The clean air treated by the air purifier 1 with the moisture separating separator 2 is separated into air and water, and is cooled or heated by the cooling heating coil 18 wound around the outer periphery of the inner cylinder 17 inside thereof to be on the conduit 19 side. To be released. The conduit 19 is connected to a duct 21 having a fan 20, and the duct 21 has a discharge port (not shown) on the indoor side, from which clean air is discharged into the room. A photocatalyst agent 12 and an ozone lamp 13 are provided in the duct 21.

  The pump 1c is connected to a separator 3 that performs oil-water separation of treated water (groundwater). The separator 3 is connected to an oil separation tank 4 into which the separated oil is introduced and an electrolyzer 5 that performs water ion decomposition. Is done. The electrolyzer 5 is connected to a washing water tank 6 for temporarily storing groundwater. In addition, ground water in the vicinity of the ground surface is pumped into the washing water tank 6 by a pump 22, and from here, the ground water is sent to the air purifier 1 side by a pump 23. In FIG. 1, a cooling / warming water tank 7 is connected to the washing water tank 6, and the pump 22 is connected to the cooling / warming water tank 7, and a part of ground water in the cooling / warming water tank 7 is sent to the washing water tank 3 side. The pump 23 is then sent to the spray chamber 1a of the air purifier 1 and sprayed. Further, a boiler 8 for heating the groundwater in the cooling / warming water tank 7 is connected, and is heated while being circulated by a boiler circulation pump 24. The water in the cold / warm water tank 7 is connected to the cooling / heating coil 18 of the moisture decomposition separator 2 by the cold / hot water pump 25 to send cold water or hot water.

  On the other hand, the water overflowing from the washing water tank 6 is added with the flocculant from the flocculant tank 10 and swirls into the tornado type mixing device 9 and mixed with the flocculant to be chemically changed and rendered harmless (for example, Chlorine is mixed into metal-rich water to form iron oxide). Next, the tornado-type mixing device 9 is connected to the adsorption tank 11 where ions are removed by the adsorbent, and then discharged to return to the soil.

  Next, the cleaning and purification action by the above components will be described. The groundwater pumped into the washing water tank 6 is sent to the spray chamber 1a side of the air purifier 1 by the pump 23 and sprayed from the nozzle 26 into the spray chamber 1a. On the other hand, contaminated air is introduced into the spray chamber 1a from the conduit 14. Here, contaminated air comes into contact with sprayed groundwater and is washed. It is known that when water is injected into air, dirt and odor in the air are removed and a large amount of negative ions are generated. In the case of the present invention, negative ions of 14000 to 35000 / cc were measured at the outlet of the duct 13. It is 5000 / cc in the forest area, 150 to 450 / cc in the urban area, and 5000 to 10,000 / cc in the waterfall area. In addition, air having a certain humidity has an antistatic effect.

  The air from which the dirt and odor are removed in the spray chamber 1a is guided to the illuminator 1b, where water droplets are removed, and the clean air is introduced into the moisture separation separator 2 from the discharge port 15 through the conduit 16. Here, the clean air further separates moisture and is heated to an appropriate temperature by the cooling / heating coil 18, sterilized by the photocatalyst 12 and the ozone lamp 1 in the duct 21, and discharged into the room. Although ozone lamps are very effective for sterilizing bacteria, ozone is dangerous and should not be used when people are working, but should be used only for a certain time using a timer at midnight. Thus, sufficient sterilization is performed.

  It is desirable that the temperature of the clean air is substantially constant throughout summer and winter. Since the groundwater maintains a temperature of 15 ° C. to 16 ° C., heat exchange with high-temperature air is performed by supplying the groundwater as it is even in summer, and the temperature of the air can be set to a desired low temperature state. In winter, water at a desired temperature can be supplied by heating the ground water as it is or slightly. Thereby, the effect of energy saving is raised.

  The spray water that has been cleaned of dirty air and accumulated under the air purifier 1 is sent to the separator 3 by the pump 1c and separated from heavy oil and oil by a swirling action. The separated oil is guided to the oil separation tank 4 and discharged. The separated water enters the electrolyzer 5 and is ion-decomposed and introduced into the washing water tank 6. The water overflowed in the washing water tank 6 enters the tornado mixing device 9. In addition, the flocculant is added just before entering, and the water is mixed with the flocculant while swirling in the tornado mixing device 9, and the agglomeration proceeds due to a chemical change (for example, when chlorine is mixed in water with a high iron content, Become). Next, water enters the adsorption tank 11 and is ion-removed and discharged. By discharging this water into the field or returning it to the ground, purified water is supplied to the field, and the soil is improved and purified. In addition, a tornado mixing device may be provided later with a sedimentation tank to precipitate the substance changed by the agglomeration effect (or a means for separating by a separator and adsorbing it through an activated carbon filter). There are also means to remove.

  The components shown in FIG. 1 may be further connected as a whole to constitute the apparatus as a whole, but these may be housed compactly in one housing and made movable.

  In the above description, the ground water is sent to the cold / warm water tank 7 and the washing water tank 6, but an example of the means for pumping the ground water in a predetermined site will be described with reference to FIG. In FIG. 2, the code | symbol 27 is a site which desires soil purification. A plurality of shallow wells 28 for pumping up groundwater are arranged in the vicinity of the boundary line of the site 27. In FIG. 2, it consists of ten shallow wells 28. The groundwater pumped up from the shallow well is connected to the spray chamber 1a of the air purifier 1. In the case of FIG. 2, three rows of air cleaners are arranged. As described above, the contaminated air in the site 27 is cleaned, and the treated water is returned to the basement again. Thereby, purification of the site 28 is performed. Disposing the plurality of shallow wells 28 on the site 27 purifies the soil in the site 27. In addition, by pumping up the ground water, the water level is lowered, groundwater flowing to the other site 27 is prevented, and the purified water is returned to the site 27 so that the soil can be purified more effectively. A part of the used water is stored in the drainage adjustment tank 29. This tank may be of an appropriate size and is used for fire prevention tanks, discharge tanks and other miscellaneous water. Moreover, when there is much water quantity, you may use for fish farming and other uses.
