Description

[0001] The present invention relates to an offensive odor treatment apparatus,

The present invention relates to a malodor removing apparatus, and more particularly, to a malodor removing apparatus capable of efficiently removing malodor of high-temperature odor gas.

In the sewage treatment plant, the wastewater end treatment plant, the livestock and manure treatment plant, the compost plant and the food waste treatment plant, the food production plant and the pharmaceutical factory, severe odor is generated in the process of treating various substances such as wastewater and chemicals. Such odor stimulates a person's smell and causes people to feel discomfort and disgust.

The substances that cause odor vary greatly depending on the source, but the main substances include sulfur compounds such as hydrogen sulfide and mercaptan, nitrogen compounds such as ammonia amine, volatile organic compounds such as benzene, toluene, ethylbenzene, xylene and volatile sulfur compounds .

In order to remove such odors, there is a method of injecting a malodorous gas that generates odor into the wet scrubber and then spraying a chemical liquid containing a drug that reacts with the malodorous substance into the wet scrubber and reacting with the malodorous gas .

When the malodorous gas is a high-temperature gas, the chemical solution is in contact with the exhaust gas and the temperature rises, so that the drug contained in the chemical solution evaporates and the deodorization efficiency by the chemical solution is lowered. In order to solve such a problem, it is necessary to continuously replenish the drug, but since the drug used to remove the odor is expensive, there is a problem that the cost for removing the odor is greatly increased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are provided by way of example so that those skilled in the art can fully understand the spirit of the present invention. Therefore, the present invention is not limited to the embodiments described below, but may be embodied in other forms. In the drawings, the width, length, thickness, etc. of components may be exaggerated for convenience. Like reference numerals designate like elements throughout the specification.

1 is a schematic view showing a state where an embodiment of a malodor removing apparatus according to the present invention is installed in a wet scrubber. 1, an embodiment of a malodor removal apparatus according to the present invention includes a malodor removing chamber 110 including a gas cooling unit 130 and a malodor removing unit 120, a gas cooling unit 130, And includes various components installed in the reject 120. In this embodiment, the malodor removal chamber 120 is integral with the top of the wet scrubber 10. The malodor removing apparatus according to the present invention can be installed integrally with various structures such as a chimney for discharging odorous gas at a high temperature and a duct connected to a device for generating odor gas as well as a wet scrubber. Hereinafter, a malodor removing apparatus integrally combined with the wet scrubber 10 will be described as an example. The wet scrubber 10 also serves to remove odors. However, if the odor is not completely removed by the wet scrubber 10, the odor removing apparatus according to the present invention can be installed in the wet scrubber 10.

The malodor removal chamber 110 is arranged to discharge the hot odor gas discharged from the outlet of the wet scrubber 10 from the gas cooler 130 and recovered from the gas cooler 130, 130). ≪ / RTI > That is, the liquid 1 used in the wet scrubber 10 and the cooling water in the malodor removal chamber are not mixed with each other.

The cooled odor gas is immediately recovered after being injected into the odor eliminator 120 and comes into contact with the chemical liquid circulated only in the odor eliminator 120. At this time, the drug in the chemical liquid reacts with the odor generating substance in the odor gas to remove the odor. When the malodor generating material is a volatile organic compound, the volatile organic compound is decomposed after the drug is adsorbed by the volatile organic compound, and the odor is removed. Here, since the chemical liquid reacts with the odor gas sufficiently cooled by the gas cooling unit 130, the temperature of the chemical liquid does not rise. Therefore, the evaporation of the drug in the drug solution can be minimized, and the amount of drug to be supplemented can be minimized in order to maintain an appropriate concentration of the drug solution.

The malodor removing chamber 110 includes an inlet 111 through which hot odor gas discharged from the wet scrubber 10 is introduced, an outlet 113 through which odor gas introduced after the inlet odor is purified, And a sidewall 112 forming an inner space 114 that flows from the outlet 113 to the outlet 113. [

The inlet 111 side of the inner space 114 of the malodor removal chamber 110 functions as the gas cooling unit 130 and the outlet 113 side serves as the malodor removal unit 120.

The gas cooling unit 130 is provided with a cooling water injection nozzle 131 and a cooling water guide plate 133 which are cooling water supply devices for injecting cool cooling water for cooling the hot odor gas. The cooling water injection nozzle 131 is installed at an upper portion of the gas cooling unit 130. In the cooling water injection nozzle 131, cold cooling water is uniformly sprayed at an angle of about 120 degrees. A cooling water guide plate 133 is provided below the cooling water injection nozzle 131. A cooling water storage portion 132 is provided under the cooling water guide plate 133.

The cooling water guide plate 133 serves to form a path along which the hot odor gas flows together with the side wall 112 of the odor elimination chamber 110. In addition, it serves to guide the cooling water injected from the cooling water injection nozzle 131 to the cooling water storage part 132. And serves to form the cooling water curtain 3 on the flow path of the malodorous gas. The odor gas is not discharged to the outlet 113 without passing through the cooling water curtain 3 because the cooling water curtain 3 blocks all the paths through which the odor gas flows. Therefore, the odor gas and the cooling water are brought into complete contact with each other. In the present invention, the frequency of contact between odor gas and cold cooling water can be increased simply by increasing the number of cooling water guide plates 133.

In this embodiment, the cooling water guide plate 133 extends from the side wall 112 toward the inner space 114. The cooling water guide plate 133 extends in a downwardly inclined state so as to allow the cooling water to flow to the cooling water storage part 132. The remaining space is blocked by the pair of cooling water guide plates 133 so that the odor gas can flow into the space between the pair of cooling water guide plates 133. [ The cooling water which has struck the cooling water guide plate 133 flows downward along the cooling water guide plate 133 and falls from the end of the cooling water guide plate 133 to the cooling water storage part 132 like waterfall water, And the cooling water curtain 3 is formed between the two portions 132. [

The cooling water stored in the cooling water storage part 132 is cooled again by various kinds of cooling devices 150 and then supplied to the cooling water injection nozzle 131 again. For example, various types of cooling devices such as a cooling tower, a cooling coil, and a heat exchanger can be used.

The cooling water stored in the cooling water storage part 132 is recovered immediately after the temperature is slightly elevated by heat exchange with the hot odor gas and then cooled by the cooling device 150 again. Since the cooling water is used only for cooling the gas, the cooling device 150 can cool the cooling water with a small amount of cooling heat.

The malodor removing unit 120 is the same as the gas cooling unit 130 except that a chemical liquid is used instead of the cooling water. The malodor removing nozzle 120 is provided with a chemical liquid guide plate 123 below the chemical liquid spraying nozzle 121. The chemical liquid spraying nozzle 121 is provided with a chemical liquid guide plate 123, Respectively. And a chemical liquid reservoir 122 is provided below the liquid medicament guide plate 123. The chemical solution stored in the chemical solution storage part 122 is supplied to the chemical solution injection nozzle 121 again by the chemical solution circulation device 140 as shown in Fig. The chemical liquid circulation device 140 may be a circulation pump.

Natural drugs such as persimmon leaf extract, pine tree extract, and pine tree extract, which contain a large amount of tannic acid, can be used as drugs to be added to the chemical solution. When the volatile organic compound is removed, an oil that is well dissolved in water can be used as a drug.

Hereinafter, the operation of the malodor removing apparatus according to the present embodiment will be described.

The high-temperature odor gas generated in the process of treating various substances such as wastewater and chemicals in a sewage treatment plant, a waste water end treatment plant, a livestock and manure treatment plant, a compost plant and a food processing plant, a food production plant, Chimneys, and ducts.

The high-temperature odor gas flows into the inlet 111 of the malodor removal chamber 110 of the malodor removing unit which is integrally combined with the structure in which the high-temperature odor gas is discharged, such as the wet scrubber 10, the chimney, and the duct.

The high temperature odor gas passes through the cooling water curtain 3 formed in the gas cooling unit 130 of the malodor removal chamber 110 while the temperature of the high temperature odor gas is about 110 ° C, When the cooling tower is used, it is cooled to less than 30 占 폚 in summer and less than 10 占 폚 in winter, and flows into odor eliminator 120.

Cooling water having a slightly increased temperature in the process of cooling the odor gas at a high temperature is firstly stored in the cooling water storage part 132, and is transferred to the cooling device 150 and then cooled. The cooled cooling water is supplied to the cooling water injection nozzle 131 along the circulation pipe 134 again.

The cooled odor gas passes through the drug solution curtain (2) formed in the odor eliminator (120), and the odor is removed.

Since the temperature of the malodor gas is sufficiently lowered in the process of passing through the coolant curtain 3, even if the malodor gas and the chemical liquid come into contact with each other, the temperature of the chemical liquid does not substantially rise. Therefore, evaporation of the drug in the chemical liquid can be minimized. The chemical liquid stored in the chemical liquid storage unit 122 is supplied again to the chemical liquid injection nozzle 121 through the chemical liquid circulation unit 140. [

FIGS. 2 to 5 are views showing structures inside the malodor removal chamber according to another embodiment of the present invention.

As shown in Fig. 2, in this embodiment, one cooling water storage unit 132 is provided on the left and right sides, respectively. The configuration of the cooling water guide plate 133 is changed.

The cooling water guide plate 133 includes a first cooling water guide plate 133a and a pair of second cooling water guide plates 133b.

The first cooling water guide plate 133a is inclined so that the cooling water flows to both the left and right cooling water storage parts 132 in the drawing.

The pair of second cooling water guide plates 133b is provided between the first cooling water guide plate 133a and the nozzle 131 and guides the cooling water injected from the nozzle 131 to drop it on the first cooling water guide plate 133a. The pair of second cooling water guide plates 133b extend from the side walls 112 facing each other toward the center of the inner space 114. [ The cooling water flowing along the pair of second cooling water guide plates 133b falls onto the first cooling water guide plate 133a to form the cooling water curtain 3.

The high temperature gas including the water vapor flowing in the downward direction in the drawing passes through the cooling water curtain 3 formed between the first cooling water guide plate 133a and the cooling water storage part 132, the second cooling water guide plate 133b, Flows through the cooling water curtain 3 formed between the cooling water curtains 133a and then flows upward in the direction in which the outlet is formed. If necessary, a third cooling water guide plate having the same shape as that of the first cooling water guide plate 133a may be provided on the cooling water guide plate 133b, and cooling water guide plates may be provided thereon.

The first cooling water guide plate 133a and the second cooling water guide plate 133b may be disposed at different positions and only one cooling water storage unit 132 may be provided at the lower center of the inner space 114. [

3, the cooling water curtains 3 are formed by using the cooling water guide plates 133 extending from the side walls 112 opposed to each other with a height difference to guide the cooling water to the cooling water storage part 132 It is possible.

The embodiment shown in FIG. 4 shows a method of constructing the cooling water guide plate 133 to guide the cooling water injected from the plurality of nozzles 131 when the inner space 114 is wide. As shown in Fig. 4, in the width direction of the inner space 114, the third cooling water guide plates 133c extending in an inclined downward direction from the side wall 112 and the pair of third cooling water guide plates 133c extending in the opposite directions The fourth cooling water guide plates 133d having the inclined surfaces are appropriately arranged to form a path through which the outside air flows and the cooling water can be guided to the cooling water storage part 132 while forming the cooling water curtain 3 on the path of the outside air have.

The first cooling water guide plate 133e and the pair of second cooling water guide plates 133f may extend horizontally from the side wall 112 as shown in FIG. In addition, the end portion may be inclined.

FIG. 6 is a schematic view showing a state in which another embodiment of a malodor removing apparatus according to the present invention is installed in a wet scrubber. The present embodiment differs from the embodiment shown in Fig. 1 only in the structure of the gas cooling unit 130, and therefore only the description will be given. In the present embodiment, the gas cooling unit 130 is provided with a support plate 30, a plurality of gas cooling cylinders 40, and a cooling water storage plate 50.

The support plate 30 is installed between the malodor removing unit 120 and the inlet 111. The support plate 30 may be coupled to the inner surface of the malodor removal chamber 110 by welding or the like. As shown in FIG. 7, the support plate 30 is in the form of a plate that intercepts the inner space 114 of the malodor removal chamber 110, and a plurality of first through holes 31 are formed. In the present embodiment, the first through holes 31 are circular, but may be rectangular or polygonal. The support plate (30) serves to support a plurality of gas cooling cylinders (40).

The gas cooling cylinder 40 serves to cool the high-temperature odor gas by using the cooling water.

8, the gas cooling cylinder 40 includes a cylinder 41 having both ends thereof opened, a cooling water injection nozzle (not shown) provided at an upper portion of the cylinder 41 for injecting cooling water into the inside of the cylinder 41 42 and a cooling water guide plate 43.

In the present embodiment, the cylindrical body 41 is generally cylindrical, and a latching protrusion 44 protruding in the circumferential direction is formed at the upper end of the cylindrical body 41 so as to be caught by the upper surface of the support plate 30. The tubular body 41 can be detachably coupled to the support plate 30 using a bolt or the like.

The cooling water jetting nozzle 42 is installed in the upper part of the inside of the cylinder 41. In the cooling water injection nozzle 42, cold cooling water is evenly injected at an angle of about 120 degrees. A cooling water guide plate (43) is provided under the cooling water injection nozzle (42).

The cooling water guide plate (43) serves to form a path through which hot odor gas flows together with the inner wall of the cylinder (41). Further, it serves to guide the cooling water injected from the cooling water injection nozzle 42 to the cooling water storage plate 50. And serves to form the cooling water curtain 3 on the flow path of the hot odor gas. Since the cooling water curtain 3 blocks all the paths through which the exhaust gas flows, the hot odor gas is not discharged to the outlet 113 without passing through the cooling water curtain 3. Therefore, hot gas of odor and cooling water are brought into perfect contact with each other. In the present invention, the frequency of contact between the high-temperature odor gas and the cold cooling water can be increased simply by increasing the number of the cooling water guide plates 43.

In this embodiment, the cooling water guide plate 43 includes a pair of first cooling water guide plates 43a, a second cooling water guide plate 43b, a pair of third cooling water guide plates 43c and a fourth cooling water guide plate 43d .

A pair of first cooling water guide plates (43a) extend from the inner surfaces of the cylinder (41) facing each other toward the center of the cylinder (41). The pair of first cooling water guide plates 43a is provided between the second cooling water guide plate 43b and the cooling water injection nozzle 42 and guides the cooling water injected from the cooling water injection nozzle 42 to the second cooling water guide plate 43b, On top. The pair of first cooling water guide plates 43a extend in a downwardly inclined state so as to allow the cooling water to flow to the second cooling water guide plate 43b. The remaining space is blocked by the pair of first cooling water guide plates 43a so that the exhaust gas can flow into the space between the pair of first cooling water guide plates 43a. The cooling water hitting the first cooling water guide plate 43a flows downward along the first cooling water guide plate 43a and falls from the end of the first cooling water guide plate 43a to the second cooling water guide plate 43b like waterfall water, A cooling water curtain (3) is formed between the end of the guide plate (43a) and the upper surface of the second cooling water guide plate (43b).

The second cooling water guide plate 43b is inclined such that the central portion thereof is higher and the height thereof is lowered toward both ends so as to allow cooling water to flow to the pair of third cooling water guide plates 43c. The remaining space is blocked by the second cooling water guide plate 43b so that hot odor gas can flow only through the space between the second cooling water guide plate 43b and the inner surface of the cylinder 41. [ The cooling water that strikes the second cooling water guide plate 43b flows downward along the second cooling water guide plate 43b and falls to the third cooling water guide plate 43c like waterfall water at the end of the second cooling water guide plate 43b, A cooling water curtain 3 is formed between the end of the guide plate 43b and the upper surface of the third cooling water guide plate 43c.

In the same manner, the cooling water that has fallen to the third cooling water guide plate 43c falls again to the fourth cooling water guide plate 43d. In this process, the cooling water curtain 3 is formed. The cooling water that has fallen on the fourth cooling water guide plate 43d falls on the cooling water storage plate 50 to form the cooling water curtain 3.

By using a plurality of gas cooling cylinders 40, each of which has a size relatively smaller than that of the cleaning case 10, it is possible to minimize the occurrence of a drift in the cleaning liquid or the high-temperature odor gas.

A cooling water storage plate (50) is installed below the plurality of gas cooling cylinders (40).

6 and 9, a plurality of second through holes 51 are formed in the cooling water storage plate 50 at positions corresponding to the plurality of first through holes 31 of the support plate 30. As shown in FIG. The diameter of the first through hole 51 is smaller than that of the first through hole 31. In the periphery of the plurality of second through holes 51, cylindrical wall surfaces 52 extending in the direction of the gas cooling cylinder 40 are formed. The hot odor gas flows into the inner space of the cylindrical wall surface 52 and the space surrounded by the cylindrical wall surface 52 and the upper surface of the cooling water storage plate 50 and the inner surface of the side wall 13 of the cleaning case 10 The cooling water separated from the cooling water guide plate 43 is stored.

10, a sloped surface 55 surrounding the second through hole 51 is formed on the lower surface of the cooling water storage plate 50. As shown in FIG. The inclined surface 55 is inclined so as to be further away from the central axis of the second through hole 51 as it advances toward the inlet 11 side of the cleaning case 10. [ That is, it is inclined to induce the high-temperature odor gas into the second through-hole 51. Since the high-temperature odor gas striking the cooling water storage plate 50 by the inclined surfaces is well distributed to the respective gas cooling cylinders 40 and flows into the respective gas cooling cylinders 40, there is an advantage that it is possible to prevent the occurrence of drift in the high- .

The cooling water 4 stored in the cooling water storage plate 50 is supplied to the cooling apparatuses 59 of various kinds by the cooling water circulation pipe 57 to be cooled again and then supplied to the cooling water injection nozzle 42 again. For example, various types of cooling devices such as a cooling tower, a cooling coil, and a heat exchanger can be used.

The cooling water (4) stored in the cooling water storage plate (50) is immediately recovered in a state where the temperature is slightly raised by heat exchange with the hot, high-temperature odor gas, and then cooled again by the cooling device (59). Since the cooling water is used only for cooling the hot odor gas, the cooling device 59 can cool the cooling water with a small amount of cooling heat.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.

For example, although the malodor removal chamber is described as having one malodor removal unit, a plurality of the malodor removal units may be provided in series.

In addition to the cooling water injection nozzle, various types of cooling water such as a cooling water reservoir configured to flow over the stored cooling water downward, a cooling water pipe configured to directly supply cooling water on the surface of the cooling water guide plate, A feeding device may be used.

In addition, although it has been described that the chemical liquid injection nozzle is used as the chemical liquid supply device, various types of chemical liquid supply devices can be used as well as the cooling water supply device described above.

The structure of the cooling water guide plate shown in Figs. 2 to 5 may also be used as the structure of the chemical liquid guide plate.
