Description

Multi-stage gas-liquid contact deodorization device using multi-stage baffle-type gas-liquid contact device{ MULTI-STAGE GAS-LIQUID CONTACT APPARATUS USING MULTI-STAGE BAFFLE TYPE GAS-LIQUID CONTACT APPARATUS}

The present invention relates to a chemical contact deodorization device using a multi-stage baffle-type gas-liquid contact device. In particular, a gas generated from a sewage treatment plant, a livestock excreta treatment plant, a manure treatment plant, or a wastewater treatment plant is contacted with one or more kinds of deodorizing chemicals to deodorize it. It relates to a multi-stage chemical contact deodorizing device that deodorizes and eliminates odors of various components contained in gas through a multi-step process.

Environmental basic facilities such as sewage treatment plants, incinerators, food waste treatment facilities, and landfills generate air pollutants and odors. The odor generated in the environmental infrastructure includes gas components that cause pain by stimulating the human mind and nervous system, such as ammonia, methyl mercaptan, hydrogen sulfide, methyl sulfide, methyl disulfide, trimethylamine, acetaldehyde, styrene, etc. . Concentrations of these substances are regulated and controlled by law.

In order to remove the odor emitted from these basic environmental facilities, various gas-liquid contact deodorizing devices and methods are currently being researched and developed. As a representative method, the chemical cleaning method is a method of cleaning odorous substances that are not very soluble in water but react with an aqueous solution of acid or alkali or that react with a specific chemical with an acid or alkali cleaning solution. In this method, ammonia, amines, Removes odorous substances such as hydrogen sulfide and methyl mercaptan.

In the gas-liquid contact deodorizing device, various gas-liquid contact devices have been developed and proposed to increase the contact efficiency between the gas component including the odor and the liquid to absorb the odor component. For example, such a gas-liquid contact device is disclosed in Patent Document 1.

In the case of the gas-liquid contact device of Patent Document 1, in order to evenly spread the cleaning solution over the entire cross-sectional area of the gas-liquid contact space, a sponge (a kind of filler) dripping method or a perforated plate type uniform distribution module 6 is used. . However, this equal distribution module (6) method reduces the contact area between the gas and the liquid by blocking the passage (channel) through which the gases to be cleaned pass by the partition walls between the holes of the sponge tissue or the perforated plate, so the contact efficiency is reduced. low. In addition, since the total cross-sectional area of the passage (channel) through which the gases pass is reduced to generate pressure, there is a disadvantage in that the scale of the facility increases, such as having to use a high-output blower for the passage of the gas.

In addition, the gas-liquid contact device of Patent Document 1 has a disadvantage in that the overall scale of the facility increases because a plurality of bulky fillers are arranged and used.

Expression second into the second gas-liquid contacting chamber (R2) so that the second bubble cap (211A) and the gas flowing into the inner space of the second gas-liquid contacting chamber (R2) come into contact with the second chemical (L2) to be cleaned A multi-stage gas-liquid contact deodorizing device using a multi-stage baffle-type gas-liquid contact device having a second chemical liquid supply pipe (Pa) for spraying the chemical liquid (L2). 3. The method of claim 2,
The rotationally floating first bubble cap 211,
The gas in the lower second chemical liquid storage tank 203 passes into the upper first gas-liquid contact chamber R1, but the second chemical liquid L2 stored at the bottom of the first gas-liquid contact chamber R1 is the second In order not to flow back into the chemical storage tank 203, the first bottom plate 202 is installed to protrude into the inner space of the first gas-liquid contact chamber R1, and a plurality of gas outlets 212a are provided along the circumference at the upper end of the side wall. a gas passage pipe 212 formed; and
A multi-stage gas-liquid contact deodorizing device using a multi-stage baffle-type gas-liquid contact device having a cover 213 placed on the upper end of the gas passage pipe 212 and having a plurality of gas outlets 213a formed along the periphery on the side wall. . According to claim 1,
The first liquid multi-stage washing unit 100,
After the odor is removed through the quaternary gas-liquid contact part 40 , the gas moving to the upper part of the internal space 104 of the first housing 105 is transferred to the tertiary chemical solution provided on the upper side of the first housing 105 . A multi-stage baffle-type gas-liquid contacting device further comprising a fifth gas-liquid contacting part for deodorizing odor components by contacting the first chemical sprayed from the third chemical liquid injection nozzle N3 of the supply pipe PL3 and the first housing 105 in the first housing 105 . A multi-stage gas-liquid contact deodorization device using
