Description

Apparatus for removing bad smell by ozone water with two steps}

The present invention relates to a device for removing odors, and more particularly, to a device for removing odors generated in an aversion facility with ozone water over two stages.

In general, gases generated from hate facilities, etc., generate odors.

As a method of removing the odor gas, there is a method of installing a plurality of nozzles in a deodorizing device and spraying water on a gas containing odor introduced into the deodorization tank at a deodorant facility (water washing method). A method in which a layer of an adsorbent such as activated carbon, silica gel, and zeolite is disposed in the tank to adsorb odor substances (activated carbon adsorption method) or a method in which a specific microbial layer is disposed instead of the adsorbent so that the microorganisms decompose odor-generating substances (microbial contact Method), etc.

However, the above methods have limitations in removing odors containing acidic and alkaline components, and there is a consideration to remove the odors using a single cleaning solution instead of water in the water washing method, but this also removes only one of the acidic and alkaline components. It has a problem that it cannot remove all odor components.

An apparatus for removing odors for solving this problem is disclosed in Patent Registration No. 10-2128552, which has been applied by the present applicant and registered as a patent.

The disclosed apparatus for removing odor includes: an alkaline cleaning liquid tank and an acidic cleaning liquid tank mounted adjacent to the base in parallel; A main body housing mounted on the alkaline cleaning liquid tank and the acidic cleaning liquid tank and standing upright; A first neutralization reaction unit connected to the discharge side of the gas inlet pipe which is built in the lower end of the main housing and has a suction side connected to the discharge side of the blower connected to the odor generating source; A second neutralization reaction unit built into the main body housing above the first neutralization reaction unit to allow circulation to the first neutralization reaction unit; A radix separation demister built into the main housing above the second neutralization reaction unit; And an exhaust port provided at an upper end of the main housing,

The first neutralization reaction unit includes: a first reaction plate disposed at a position higher than the gas inlet pipe and covering a lower portion of the main housing; A wall portion formed by standing on one side of an upper surface of the first reaction plate; An acidic cleaning liquid circulation pipe through which one side of the first reaction plate is opened to circulate the acidic cleaning liquid flowing through the wall portion into the acidic cleaning liquid tank; And a suction side connected to the acid washing liquid tank and a discharge side connected to the discharge side of the acid washing liquid circulation pump connected to the first neutralization reaction unit, and the first reaction plate is vertically spaced apart from the first reaction plate. 1 It includes a plurality of nozzles for spraying an acidic cleaning solution on the reaction plate,

The first neutralization reaction unit further includes a plurality of inner ring orbiting nozzle units circulatingly coupled to each of a plurality of through-holes formed by having an arrangement of a grid pattern on the first reaction plate,

Each of the plurality of inner ring orbiting nozzle units may include a tubular portion provided by standing up on the first reaction plate by forming a spiral portion of a plurality of rows extending in a vertical direction on an inner circumferential surface while flowing through each of the plurality of through holes; A flange portion fixedly circumscribed to the upper end of the tubular portion; A circular wall mounted on the edge of the plurality of flanges to be disposed in the acidic cleaning solution accumulated on the first reaction plate, and having a plurality of pores formed at intervals in the vertical direction and the circumferential direction; A cover provided at an upper end of the circular wall to close the upper end of the circular wall; And a plurality of wing portions extending radially outwardly and streamlined from the center of the underside of the cover,

The second neutralization reaction unit is configured to be substantially the same as the first heavy reaction unit,

A partition wall having a flow port formed between the first and second neutralization reaction portions is provided, and a hatchet-shaped portion is provided in the flow port.

However, in the disclosed odor removal apparatus, a vortex of odor gas discharged through the plurality of inner ring orbiting nozzle units provided in the first and second neutralization reaction units occurs only around each of the plurality of inner ring orbiting nozzle units, The accumulated chemical liquid accumulated in the first and second reaction plates of the first and second neutralization reaction units does not flow as a vortex along the edges of the first and second reaction plates as a whole, but flows only locally as a vortex. Not only does some of the malodorous gas react with each other, but also the malodorous gas that has escaped from the accumulated chemical liquid is generated only around the plurality of inner ring rotating nozzles, through the nozzle over the entire area of the space of the first and second neutralization reaction units. There is a problem that the odor removal gas removal efficiency is poor because it reacts by contacting a part of the sprayed chemical liquid.

Moreover, when ozonated water, which has better odor removal efficiency than acidic or alkaline chemicals, is applied to the above-described odor removal device instead of acidic or alkaline chemicals, the amount of ozone water that has not reacted with the odorous gas is vaporized and is discharged to the outside. The odor removal device disclosed above has.

In addition, in the disclosed odor removal apparatus, the odor gas entering the hatch-shaped distribution port provided between the first and second neutralization reaction units moves upward in the direction of gravity, and then hits the hatchet-shaped part and inclines downward to be discharged outward. Therefore, there is a problem that the vertical component airflow force of the malodorous gas entering the distribution port is weakened by the airflow force of the downward component generated in the hatchet shape, and the second medium-lower reaction section, the next step, cannot enter the desired pressure. .

The present invention has a problem in solving the above problems.

In the present invention, the neutralization treatment of the odor gas is made with ozone water, and a plurality of the first and second reaction plates are disposed on the first and second reaction plates of the first and second neutralization reaction units at intervals along the edges of the first and second reaction plates. A plurality of bending nozzles are provided to suck odor gas in a vertical direction and discharge it in a horizontal direction so as to discharge odor gas in one direction of the rim trajectory of the first and second reaction plates, and between the first and second neutralization reaction parts. The above problem can be solved by replacing the provided conventional hatchet-shaped flow port with an inner ring rotating nozzle provided in the first and second neutralization reaction units.

In the present invention, a vortex of odor gas discharged through a plurality of bending nozzles provided in the first and second neutralization reaction units is generated along the edges of the first and second reaction plates of the first and second neutralization reaction units. Accumulated ozone water accumulated in the first and second reaction plates of the first and second neutralization reaction units as a whole flows as a vortex along the edges of the first and second reaction plates, so that the entire accumulated ozone water and odor gas react with each other. In addition, the odor gas that has escaped from the accumulated ozone water is also distributed over all areas of the first and second neutralization reaction units, and all of the ozone water sprayed through the nozzles over the entire area of the space of the first and second neutralization reaction units and By contacting and reacting, the odor removal gas removal efficiency can be significantly increased compared to the conventional one.

Moreover, in the present invention, even when ozone water having a better odor removal efficiency than acidic or alkaline chemicals is applied to the first and second neutralization reaction units instead of acidic or alkaline chemicals, ozone contained in ozone water reacting to malodorous gases is increased. , It is possible to significantly reduce the amount of ozone vaporized in ozone water and released to the outside.

In addition, in the present invention, a plurality of inner ring orbiting nozzle units are provided between the first and second neutralization reaction units, and the odor gas entering the distribution port is moved upward in the direction of gravity and then discharged in a radial direction outward from the horizontal direction. It is possible to make it possible to reduce the force of the odorless gas to enter the desired pressure in the next step, the second heavy-duty reaction unit, without increasing the ability of the blower to supply malodorous gas.
