Description

A smell remove device for car wash recycle water}

The present invention relates to an apparatus for removing the odor of car wash water, and in particular, it is possible to efficiently remove the odor smell of the water by injecting ozone into the water used for car wash.

In general, the car was washed by hand at the time of washing, but recently, an automatic device for automatically washing the car within 5 minutes while the driver is sitting in the driver's seat has been developed and used in each car wash.

In this case, a large amount of wastewater is generated compared to car wash by hand, but the wastewater purification device is not developed accordingly, so the car wash wastewater contains oil and a large amount of synthetic detergent unlike general household wastewater or livestock wastewater. If left unsecured, it causes severe water pollution and destroys the ecosystem.

Conventional car wash wastewater treatment methods are mainly agglomeration and sedimentation method by chemicals, and when treated by such chemicals treatment method, the pollution concentration of the effluent is increased, and the secondary pollution problem due to sediment is generated. Waste water from maintenance shops contains a large amount of detergents (surfactants).

In order to treat such surfactants, there are treatment methods such as chlorine injection, flocculation, sedimentation, sand filtration, etc., but it is impossible to treat them completely. As a result, the surfactants in the waste water form bubbles to reduce the oxygen transfer rate. It inhibits the growth of microorganisms due to toxicity and destroys the ecosystem.

The conventional wastewater treatment method has a problem of deterioration of wastewater treatment performance and a heavy burden on the cost of chemicals and sediment (sludge) treatment, which causes a lot of burden on the operation at small workplaces, so that some operators discharge the environment without monitoring. It becomes a serious problem to pollute.

The present invention has been devised in response to such a point, and an object of the present invention is to effectively remove odors (odors) of car wash regeneration water by injecting ozone while passing the waste water after washing through an oil / water separation tank, a sedimentation tank, and a reuse water tank. The present invention provides a deodorizing device for washing car regeneration water.

According to the present invention for achieving the above object, the ozone generator has an upper layer portion having a power connection hole and a bolt hole, an air inlet port and an ozone exhaust port, and a lower layer portion formed with a space portion in a central portion, and inserted between the space portion and the upper layer portion of the lower layer portion. It is characterized in that it comprises a ceramic plate that generates ozone when the power is applied.

As described above, the present invention injects the ozone generated from the ozone generator into the wastewater for car wash, thereby effectively removing the odor (odor) of the regenerated water for car wash.

The oil having a low specific gravity among the incoming wastewater is separated into the upper surface of the water, and the large particulate matter is gravity settled to the bottom, and the separated wastewater is sedimented with an oil / water separation tank (1) for natural emulsification into a sump. A settling tank (2) for obtaining high quality regenerated water, a reaction tank (3) for flocculating the floc to settle the floccules of the settling tank (2) by slow stirring, and a greater amount of ozone gas by supplying 98% oxygen And ions are oxidized and precipitated in the wastewater from the ozone generator (4) and the reaction tank (3) to prevent the formation of unnecessary NOx, and the organic substances are decomposed to Recycling tank (5) for securing water, discharge tank (6) in which ozone generated by the ozone generator (4) flows in and water containing ozone water is discharged, and a chemical reservoir (7) for injecting drugs And a pump 8 for pumping the wastewater of the reactor 3, a mixer 9 in which the wastewater pumped by the pump 8 and the chemical reservoir 7 are mixed with the chemicals, and the mixer 9. It consists of a filter 10 for filtering the water mixed through the).

The operation of the present invention configured as described above will be described.

In the present invention, when the wastewater used for washing is introduced into the oil and water separation tank 1, the chemicals from the reservoir 7 are also introduced into the oil and water separation tank 1 together.

Therefore, in the oil / water separation tank 1, oil having a low specific gravity in the inflowing wastewater is separated into the upper surface of the water surface, and large particulate matter is caused to gravity settle downward.

In addition, wastewater having a low specific gravity flowing out from the oil / oil separation tank 1 precipitates flocculated floc in the precipitation tank 2 so as to obtain high quality recycled water.

The regeneration water passing through the settling tank (2) is moved to the reaction tank (3), it is sent to the mixer (9) through the pumping of the pump (8), wherein the chemical from the chemical reservoir (7) is applied to the mixer (9) and mixed The regenerated water mixed through the mixer (9) is filtered through the filter (10) and sent back to the oil / water separator (1).

On the other hand, when the water level of the reaction tank 3 is above a certain level, the sensor 11 for detecting the water level detects it and sends the regeneration water of the reaction tank 3 to the reuse tank 5, and in the reuse tank 5 the reaction tank 3 It oxidizes and precipitates ionic substances in the wastewater from) and decomposes organic substances to secure quality water.

In addition, the water in the reuse tank (5) is sent to the discharge tank (6) at this time to remove the odor because ozone generated by the ozone generator (4) flows into the discharge tank (6).

Low-grade ozone generators are usually generated using atmospheric air, which generates as much as 2-3% of NOx (78% nitrogen in the atmosphere).

In order to prevent such side effects, in the ozone generator 4 of the present invention, by supplying 98% of oxygen, a larger amount of ozone gas can be generated and unnecessary generation of NOx can be prevented.

Here, the water filtered by the filter 10 is introduced into the discharge tank (6).

3 and 4 show the ozone generator 4 of the present invention, which has an upper layer 15 having a power connection hole 13 and a bolt hole 14, an air inlet 16, and an ozone outlet 17. And a ceramic plate 20 inserted between the lower portion 19 and the upper portion 15 of the lower portion 19 having the space portion 18 formed in the center, and generating ozone when the power is applied. do.

In addition, the transparent tempered glass 24 is installed on the ceramic plate 20, the ceramic plate 20 is fixed by the ceramic plate holder 21.

In the ozone generator 4, the ceramic plate 20 is inserted into and fixed in the space 18 between the upper layer 15 and the lower layer 19, and the upper layer 15 and the lower layer 19 are bolted holes 14. While coupled to the bolt through the power supply is connected through the power connection hole (13).

Therefore, when a high voltage is applied to the ceramic plate 20 through a power source, ozone is generated from the ceramic plate 20 and flows into the discharge tank 6.

Here, the principle of ozone generation is ozone is generated when the AC voltage 11000-13000 is discharged by using a transformer, usually 220V, and the ozone is thus transferred through the air intake blower 12 as shown in FIG. .

Ozone production in the present invention uses a glaze added to the ceramic plate 20, like porcelain, baked at a high temperature, and assembled in a rectangular outer space case.

This ozone is excellent in sterilization and deodorization, and is used in many fields. The car wash water treatment machine is also commercialized, and is widely used in gas stations.
