Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a chemical cleaning deodorizing apparatus using a Venturi tube and a micro-

The present invention relates to a chemical liquid cleaning and deodorizing apparatus using a venturi tube and a microbubble solution, and more particularly to a chemical liquid cleaning and deodorizing apparatus using a venturi tube and a microbubble solution, The present invention relates to a chemical liquid cleaning and deodorizing apparatus using a turbulent tube and a microbubble liquid.

Generally, in an industrial field, an unpleasant odor is generated during the production process of the product, or various odors are generated in the process of the waste water treatment.

According to the Ministry of Environment statistics in 2012, there were 7,247 complaints of bad odor, which increased by 15.1% compared to the previous year (6,297 cases). These odor complaints have been steadily increasing since 2001. The causes of odor are very diverse, and their composition and concentration are also very different.

In particular, the odor of organic wastewater / waste treatment facilities such as waste storage and treatment facilities, waste water, manure, and livestock facilities is a complex odor of organic compounds combined with atoms such as oxygen, sulfur, and nitrogen. It is roughly classified into odor (s).

As an example of a deodorizing device for removing such organic complex odors, according to Korean Patent Registration No. 10-0794208, odor is removed by acidic water and alkaline water injected from a malodor control unit, and Patent Registration No. 10-0954087 The acid gas in the malodor component adsorbs only the acid gas in the adsorbing section and adsorbs and removes only the alkali gas in the alkali gas adsorbing section.

Patent Registration No. 10-1023398 discloses that odor is removed by a collision reaction between a cleaning liquid and a malodorous component due to the injection of a cleaning liquid into a swirl flow generated by rotation of a rotating plate in a malodor control unit. Patent Registration No. 10-0636620 The odor is removed by photocatalytic filter and ultraviolet ray photochemical oxidation / reduction reaction.

Patent Registration No. 10-1174095 is a facility for deodorization by activated carbon adsorption and ultraviolet rays after firstly removing odors by a chemical solution cleaning unit.

In the case of flushing of the above-mentioned patents or deodorization by a chemical solution, the reproducibility of the malodor removal may be lowered as time goes by the change of the concentration of the chemical solution or the absorption ability of the malodor component in the chemical solution is decreased. In the case of photochemical oxidation / reduction reaction, It is pointed out that the odor removal efficiency is not so high.

On the other hand, according to Korean Patent Registration No. 10-1012725, an example similar to the technique of the present invention is that a malodorous gas is introduced into a venturi form, which is insufficient for a malodor removal system using Venturi theory.

In addition, Patent Registration No. 10-1056686 discloses a device for removing odors by mixing cavitation bubbles and swirling flow odor gas. However, there is a problem that the odor removing efficiency by these is extremely limited.

Next, referring to FIGS. 1 to 4, a method of operating a chemical liquid cleaning and deodorizing apparatus using a venturi tube and a microbubble liquid according to a preferred embodiment of the present invention will be described in detail.

The malodor air generated from the malodor generation source flows through the inflow pipe 11, and the malodor air is sucked by the suction fan 14 or the blower motor.

The odor air is absorbed, adsorbed and dissolved in the fine bubble liquid flowing into the venturi tube 12 from the bubble generator 15 generated by 5 to 10 탆 passing through the venturi tube 12.

These odor air and minute bubble liquid are momentarily contacted, mixed, collided, absorbed and dissolved in the enlarged pipe 12c. That is, the fine bubble liquid is supplied to the injection nozzle 20 by the second pump 19, and the odor air flows from the neck portion 12b of the venturi tube 12 to the high-speed airflow state to collide or mix with the microbubbles In the coaxial expansion pipe 12c, the airflow is reduced while causing a vortex flow.

At this time, since the passage velocity of the odor air passing through the neck portion 12b is maintained at least 60 m / sec or more, collision, absorption and high dissolution rate of the fine bubble liquid and the odor air can be obtained in the expansion pipe 12c.

Due to the increase of the pressure and the collision of the odor air and the microbubble liquid, the odor air is easily absorbed and dissolved in the fine bubble surface (enemy) of 5 to 10 μm. Thus, the microbubble solution absorbed, adsorbed and dissolved by the malodorous air is transferred to the neutralization reaction section 30.

Various chemical reactions occur when the fine bubble liquid is transported through the first charging part 31 and the second charging part 33 and the fine bubble liquid contacts the charging container 38 and the carrier 39.

A chemical solution for neutralizing typical ammonia (ammonia, NH ₃ ) and trimethyl / ethyl-amine ((CH ₃ ) ₃ N)

As a sulfuric acid (H ₂ SO ₄ ) solution, the reaction formula is as follows.

2 NH ₃ + H ₂ SO ₄ → (NH ₄ ) ₂ SO ₄

2 (CH ₃ ) ₃ N + H ₂ SO ₄ → ((CH ₃ ) ₃ N) ₂ SO ₄

The agent that neutralizes a typical acidic hydrogen sulfide (H ₂ S), methyl mercaptan (CH ₃ SH), or the like is caustic soda (NaOH) and is neutralized as shown in the following formula.

H ₂ S + ₂ NaOH → Na ₂ S + 2H ₂ O (or H ₂ S + NaOH → NaHS + H ₂ O)

CH ₃ SH + NaOH → CH ₃ SNa + H ₂ O

In the above reaction formula, the caustic soda aqueous solution shows a removal rate of 90% or more at a pH of 12 or more. When the pH value is about 10, the removal rate is reduced to 70 to 80%.

The reason is that hydrogen sulfide is regenerated by the reverse reaction as shown in the following equation.

H ₂ S + NaOH? NaHS + H ₂ O

_{NaHS + NaOH → Na 2 S +} H 2 O

In this case, when sodium hypochlorite (NaOCl), which is an oxidizer, is added, the following irreversible product is produced and the main reaction of hydrogen sulfide and caustic soda proceeds (forward direction) because sodium sulfide which is a reaction product is consumed to lower the concentration of sulfide.

NaS + 4NaOCl - > Na ₂ SO + 4NaCl (at about pH 10)

Na ₂ S + NaOCl + H ₂ O → NaCl + NaOH + S (PH <2 and PH> 12)

Therefore, the absorption and dissolution rates of the hydrogen sulfide are increased, and the removal rate of 90% or more is obtained at about 10 ° C.

Also, the consumption of sodium hypochlorite is the lowest at about 10 ° C.

The oxidizing agent of sodium hypochlorite easily oxidizes and decomposes odorous gases (methyl mercaptan, methyl sulfide, methyl disulfide, acetalide, etc.) other than hydrogen sulfide by reacting with many odor components as shown in the following equation.

CH ₃ SH + ₃ NaOCl - &gt; CH ₃ SO ₃ H + ₃ NaCl

_{(CH 3) 2 S + 3NaOCl} → (CH 3) 2 SO 3 + NaCl

_{(CH 3) 2 S 2 +} 5NaOCl → 2CH 3 SO 2 H + 5NaCl

CH ₃ CHO + NaOCl + NaOH → CH ₃ COONa + NaCl + H ₂ O

In the present invention, the chemical liquid cleaning and deodorizing apparatus is capable of neutralizing and oxidizing while falling down to the neutralization reaction unit 30 by water droplets (meaning 'water droplets') of microbubbles absorbed and dissolved by the odorous air.

In order to increase the neutralization and oxidation reaction efficiency, the neutralization reaction unit 30 is filled with a filling container 38 filled with a carrier 39 so as to form an appropriate layer on the filling supports 32 and 34 of the perforated plate.

By stacking the filling containers 38 in layers as described above, it is possible to prevent moonflow and drift, and the reaction efficiency is improved.
