Description

{Odor removing equipment for dryer}

The present invention relates to a deodorizing apparatus for a dryer having a novel structure capable of effectively removing contaminants which are contained in exhaust gas generated when an object is dried by using a drier to generate odor.

In general, various types of dryers used for drying grain, food waste or various other industrial wastes have been developed and widely used.

The present applicant has developed a dryer capable of effectively drying and stirring various objects, and has been patented (Patent No. 10-1472568, No. 10-1534492, etc.)

Such a dryer includes a housing having a cylindrical shape extending in the up and down direction, a housing having a charging port formed on one side of the upper portion and a discharge port formed on the lower side of the housing, a plurality of drying panels spaced apart from each other in the vertical direction inside the housing, A stirring means for stirring an object supplied to an upper surface of the panel and a heating means connected to the housing and the drying panel for heating the internal space of the housing and the drying panel, The object can be dried by heating the object directly or indirectly using the heating means while stirring the supplied object.

At this time, an exhaust pipe is connected to one side of the housing, and the steam generated when the object is dried can be discharged.

However, since the exhaust gas discharged through the exhaust pipe of the dryer contains not only steam generated from the object but also various pollutants causing odors, odor and environmental pollution occur when the exhaust gas is directly discharged to the atmosphere.

Therefore, a malodor removing device is connected to the exhaust pipe to remove contaminants that cause malodor.

FIG. 1 shows an example of such a malodor removing apparatus. In FIG. 1, a passage 11 connected to the exhaust pipe is formed therein, and exhaust gas discharged through the exhaust pipe passes through the passage 11, And a burner 20 connected to the heating tank 10 and heating the exhaust gas passing through the passage 11. [

At this time, an inlet port 12 connected to the dryer is formed on one side surface of the heating tank 10, and an exhaust port 13 is formed on the other end surface.

The burner 20 is connected to one end surface of the heating tank 10 through a connecting pipe 21 so that a high temperature combustion gas generated when the fuel is burned in the burner 20 flows into the passage 11, .

Therefore, the exhaust gas discharged through the exhaust pipe is mixed with the exhaust gas inside the heating tank 10, and thus the contaminants contained in the exhaust gas are heated and heated to be removed by thermal decomposition.

However, in order for the malodor removing apparatus to function effectively, the exhaust gas supplied through the exhaust pipe and the high-temperature combustion gas supplied by the burner 20 must be effectively mixed in the heating tank 10 , So far, no method has been developed for mixing the exhaust gas and the combustion gas.

Therefore, in the case of the conventional malodor removing apparatus, the exhaust gas and the combustion gas are not effectively mixed, the pollutants contained in the exhaust gas are not completely decomposed, and thus the generation of odor can not be completely prevented there was.

Therefore, there is a need for a new method to solve such a problem.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 to 4 illustrate a deodorizing device for a dryer according to the present invention, in which a passage 11 connected to an exhaust pipe of a dryer is formed therein so that exhaust gas discharged through the exhaust pipe flows through the passage 11 A burner 20 connected to the heating tank 10 to supply a high temperature combustion gas into the passage 11 to heat the exhaust gas passing through the passage 11, Is the same as the conventional one.

According to the present invention, first and second diaphragms 14 and 15 having through-holes 14a and 15a passing through both surfaces of the heating tank 10 are interposed in the middle of the passage 11, As shown in FIG.

In detail, the heating tank 10 is formed in a cylindrical shape extending in a downward direction and is installed at an upper end of a supporting table 16 formed by joining metal bars. At the lower end of the heating tank 10, (12) is formed, and an exhaust port (13) is formed at the upper end.

The first and second diaphragms 14 and 15 are made of a metal such as steel whose strength is not lowered even when heated to a high temperature while being strong against heat. The first and second diaphragms 14 and 15 are alternately arranged vertically in the heating tank 10 Respectively.

That is, the first diaphragm 14 is provided at the bottom of the heating tank 10, the second diaphragm 15 is provided above the first diaphragm 14, and the second diaphragm 15 And the first diaphragm 14 is provided on the upper side of the first diaphragm.

The through-hole 14a of the first diaphragm 14 is formed at the center of the first diaphragm 14 and the through-hole 15a of the second diaphragm 15 is formed at the periphery of the second diaphragm 15 .

The burner 20 is connected to the lower side of the heating tank 10 through a connecting pipe 21.

For this, a communication hole 17 is formed in the lower side of the heating tank 10 so as to pass through the upper and lower surfaces, and the connection pipe 21 is vertically connected to the communication hole 17.

At this time, the burner 20 uses a pellet boiler made of pellet as a fume.

Therefore, the pellet boiler is ignited, and the high-temperature combustion gas is supplied to the lower side of the heating tank 10 through the connection pipe 21. The high-temperature combustion gas is supplied to the inside of the heating tank 10 through the inlet port 12, When the exhaust gas is supplied to the inner lower side, the combustion gas and the exhaust gas are mixed through the through holes (14a, 15a) and then discharged through the exhaust port (13).

The through-hole 14a of the first diaphragm 14 is formed at the center of the first diaphragm 14 and the through-hole 15a of the second diaphragm 15 is formed at the periphery of the second diaphragm 15 So that the combustion gas and the exhaust gas are alternately stirred while being alternately flowing inward and outward from the inside of the heating tank 10 as shown by an arrow, The pollutants are heated to a high temperature by the heat of the combustion gas and pyrolyzed and removed.

The first and second diaphragms 14 and 15 having through holes 14a and 15a passing through both sides of the heating tank 10 are disposed in the middle of the passage 11, The through holes 14a of the first diaphragm 14 are formed at the center of the first diaphragm 14 and the through holes 15a of the second diaphragm 15 are formed at the center of the first diaphragm 14, 2 diaphragm 15 so that the exhaust gas and the combustion gas supplied from the burner 20 pass through the through holes 14a and 15a of the first and second diaphragms 14 and 15, .

Therefore, the high-temperature combustion gas and the exhaust gas are effectively mixed with each other, so that the contaminants contained in the exhaust gas can be effectively heated, pyrolyzed and removed.

Particularly, the heating tank 10 is formed in a cylindrical shape extending in the vertical direction and formed with an intake port 12 at the lower end periphery and an exhaust port 13 at the upper end. The burner 20 is connected to the connection pipe 21, To the lower side of the heating tank (10).

Therefore, there is an advantage that the exhaust gas, which has been supplied into the heating tank 10 and then mixed with the combustion gas, is naturally lifted upward and mixed with the combustion gas.

Since the first and second diaphragms 14 and 15 are made of a metal material heated by the burning gas supplied to the inside of the heating tank 10 by the burner 20, And the second diaphragms 14 and 15 are heated to a high temperature so that the first and second diaphragms 14 and 15 heated to a high temperature when the exhaust gas passes through the through holes 14a and 15a So that the contaminants contained in the exhaust gas can be more effectively heated and pyrolyzed.
