Description

[0001] The present invention relates to a deodorizing apparatus,

The present invention relates to a deodorizing device for purifying odor generated in facilities such as a sewage treatment plant, a water treatment plant, a factory, etc., and discharging the odor to the atmosphere. More particularly, To a deodorizing apparatus which further improves the performance of the deodorizing apparatus.

Conventional wastewater treatment devices have been dealt with deodorizing devices of various treatment methods such as adsorption type, chemical treatment type, biological decomposition type and the like, but most of the deodorization type is the installation site and initial investment cost and maintenance Cost and other factors, it is not only the situation where the investment cost is not expected, but it requires continuous management and cost in order to maintain the stable driving condition, and thus a lot of human and material resources are consumed.

On the other hand, as for a deodorization device using a bio filter, which is a biological decomposition method that is generally used among conventional deodorization methods,

The odor collected in the deodorizing tower configured to maintain the humidity by continuously supplying water at a predetermined time interval while forming a carrier in the middle portion flows into the lower space through the odor supply pipe, And the odor is removed by the microorganism while the odor is decomposed by the contact with the carrier which is impregnated.

The biofilter, which is a deodorizing device using such a microorganism, has a problem in that deodorizing function of microorganisms is changed according to a temperature change. Since the activity of microorganisms is considerably low during the low temperature season, There is a serious problem such as causing environmental pollution and the like.

In addition, in order to cope with a high concentration odor exceeding the malodor processing ability of the deodorizer, the system is inefficient because it is not provided with a treatment operation system suitable for the concentration.

Therefore, as a technique for solving such conventional problems, Korean Patent Registration No. 10-0510620 discloses a 'deodorizing device'.

The above-described technique includes a main body case forming an air flow path therein; An ozone generator provided in the air flow path in the main body case so as to freely flow air and serving as a light source for emitting light having a wavelength of 185 nm and 254 nm; A photocatalytic filter unit provided with a photocatalytic filter, the photocatalytic filter unit being freely installed in an air flow path in the main body case; Wherein air flow is freely provided downstream of at least one of the ozone generator and the photocatalytic filter in the air flow path in the main body case, and at least one component of potassium hydroxide and nickel nitrate is adhered to activated carbon adsorbing the odor component, , And it was proposed to overcome the disadvantage of the technique that the odor is decomposed by the conventional microorganisms with ozone, a photocatalytic filter, and an impregnated carbon.

However, the above technology is manufactured by using a resin such as FRP (fiber reinforced plastics) as a main material. Resins cause environmental pollution due to the nature of materials, and are harmful to human body and difficult to recycle. Further, since there is no separate pretreatment device capable of filtering oil and various pollutants, there is a limitation in removing fine dust and odors, and it is also difficult to replace the photocatalytic filter.
