BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dehumidifying duct having a dehumidifying duct,

The present invention relates to a swirling-type dehumidifying dehumidification method that improves dehumidification efficiency applicable to high humidity or seasons so that effective performance of biooxidation for indoor deodorization applied to various sewage treatment plants, food processing plants, Lt; / RTI >

A typical duct is a conduit that carries contaminated air from the source to the containment facility or from the containment facility to the final outlet, consisting of a main duct and a branch duct. Therefore, one or more ducts directly connected to the hood are connected to the branch pipe to carry polluted air to the prevention facility. Generally, the exhaust system consists of a hood, a duct, a fitting, and an exhaust fan.

On the other hand, a common duct is a main duct of an exhaust system. Submain ducts of a simple system are connected to the main duct, and branch ducts are connected to the main duct.

The design of the duct is as follows. First, the design of the grade and the exhaust hood suitable for the operation control and the design flow rate (design f) rate of the grade and the exhaust hood are determined. Second, determine the minimum duct velocity. Since the conveying ducts exhaust particulate matter, the minimum transport velocity must be maintained in the duct to prevent settling in the conveying duct, and the duct velocity for the vapor and gas and non-condensing fumes is not important. Third, determine the size of the branch duct by dividing the design flow rate by the minimum duct velocity. Select a duct with a slightly smaller internal diameter so that the actual duct velocity is greater than the minimum duct velocity. Fourth, the schematic is used to determine the design length for each part of the duct required, fittings, and elongation. The design length is the centerline distance along the duct, and the radius of the elbow is negligible. Fifth, calculate the pressure loss for the feed and exhaust system. The frictional action or the pressure loss due to fittings can be calculated using the velocity pressure method or the equivalent length method. At this time, the speed-pressure method is used more frequently because it is faster to use the speed-pressure method, and all losses, such as the loss of the inlet of the hood, are calculated by the same criteria. Also, since the duct is designed by the balanced method, there is an advantage that the size of the branch duct can be quickly recalculated.

For reference, dusts aspirated from the hood range in size from 0.1 micron to several millimeters in size, and are generally characterized by the fact that these dusts are not deposited in ducts and are transported to a preventive facility. The speed at which dust is carried is called the conveying speed. It is necessary to speed up the conveyance speed of the metallic dust which is heavy depending on the nature of the dust and the piping condition, the wet dust and the light dust.

The above-described air duct for air conditioning has a dehumidifying function, but in the case of industrial use, a general duct for simply introducing natural outside air without a dehumidifying function is used. In this case, in winter, indoor air drips down, affecting specific equipment or sensors, causing the machine to stop operating or making the working environment difficult, and the rainy season also increases the discomfort index at the same temperature.

Therefore, a new technology for dehumidifying exhaust air or exhaust air through the duct is required because the odor-removing working efficiency is lowered and the work environment can be lowered if the working environment generates odor.

On the other hand, indoor air conditioning plays a role of dehumidification, vibration suppression, and temperature maintenance. In particular, even at the same temperature, the lower the humidity, the lower the discomfort index felt by humans becomes. Therefore, if the humidity of the indoor air can be lowered under the room temperature regulation, the above problem can be largely solved. However, since the dehumidification for lowering the current humidity uses a method of condensing moisture in the air at a low temperature by using a refrigeration cycle, there is a problem that the cooling system must be operated for dehumidification in a general air conditioning system.

Such dehumidification is also common in the industrial field. Therefore, a separate dehumidifying device is used in order to remove moisture from the gas containing moisture, and this dehumidifying device is necessarily required to cool the gas to raise the saturated steam pressure. Therefore, in order to dehumidify while maintaining the temperature of the gas, energy for cooling the gas and energy for heating again are required. Therefore, if the absolute humidity of the input gas can be partially lowered, a considerable energy saving effect can be obtained.

Especially, when the indoor humidity is high, it is harmful to the environment and health such as the second generation of odor smell and various bacterium breeding. However, when the moisture removal is effectively performed in a place or environment where high humidity is high, It is possible to increase the efficiency of the air purifier used and reduce the malfunction rate and maintain a comfortable working environment and reduce the discomfort of the operator.

The present dehumidifying duct 100 includes a tubular duct body 110 having a drain hole 113 formed therein; A vent hole 122 is formed in a bottom surface 121a of the narrowing passage 121 and a hooking protrusion 123 is formed along the tip of the narrowing passage 121, (120); A water pipe main body 161 inserted into the duct main body 110 and inserted into the narrow passage 121 so as to receive the water dropped from the narrow passage 121 of the large horn 120, A through hole 162 formed in the water pipe main body 161 so as to communicate with the drain hole 113 and an order line 164 piped from the bottom surface of the water pipe main body 161 toward the through hole 162 A water tank 160 provided with a water tank; The swirling flow fan 140 is installed in the main water pipe main body 161 so as to face the narrowing passage 121 of the large diameter pipe 120 and rotates so as to circulate air passing through the large diameter pipe 120 , 140 '); And a drain pipe (150) which is collected at the narrowed portion (121) of the horny large pipe (120) and collects and drains water flowing down to the bottom surface of the water pipe main body (161).

The dehumidifying duct 100 of the present embodiment further includes a demister filter 130 installed in the horny bulb 120 to filter air flowing toward the narrowing 121 of the horny bulb 120. .

Hereinafter, each configuration will be described in more detail.

The duct body 110 is a circular tube or a rectangular tube, and is connected to all the ducts in a kit form, such as a spiral duct and an aluminum-made rectangular duct. The duct main body 110 of the present embodiment can be installed in a section where the duct diameter of the duct becomes narrow to increase the air flow rate, and in the case where there is a branch pipe, it can be installed at the front end of the branch pipe to increase the water removal efficiency. For reference, the duct body 110 of the present embodiment is composed of a pipe 111 and a flange 112 formed at the end of the pipe 111. Here, the flange 112 is utilized for connection with the neighboring other water pipe main body 161.

The conical large-diameter pipe 120 is formed in a tubular shape having a narrowed portion 121, and is inserted into the duct body 110. Therefore, the air moving along the duct body 110 flows into the horn bulb 120 and is discharged through the narrow passage 121. For reference, the air passing through the narrowing passage 121 rapidly rises and the temperature is lowered, so that the water vapor contained in the air is liquefied and discharged from the narrowing passage 121. In this process, water is concentrated in the narrowing passage 121 . The condensed water forms a water droplet. When the weight exceeds a predetermined weight, the condensed water is discharged to the outside of the horn-shaped pipe 120 through the narrowing passage 121 by receiving the exhaust pressure of the air passing through the narrow-

The conical tube 120 is inserted into the duct body 110 and has a discharge hole 122 formed in a bottom surface 121a of the narrowed tube 121 and is provided with a hook- 123 are formed. Therefore, the air introduced into the horn 120 is exhausted through the narrow passage 121, and vortex is generated as it passes through the locking protrusion 123. In this process, water vapor condenses on the front surface of the locking protrusion 123, . As a result, the air passing through the narrowed portion 121 is subjected to the primary dehumidification treatment, and the generated moisture falls into the water pipe 160 through the discharge hole 122. The bottom surface 121a of the narrowing groove 121 forms a concave water channel so that the water condensed on the entire surface of the bottom surface 121a and the locking projection 123 flows toward the center of the concave water channel, And is discharged to the discharge hole 122 located at the center of one side of the surface 121a.

The conical large-diameter pipe 120 of this embodiment has an end connected to one end of the discharge hole 122 adjacent to the locking projection 123 and suspended in the direction of the order line 164, And a guide line 124 in which a water channel 124a having a concave shape is formed along the longitudinal direction so that the drained water flows to the order line 164.

As shown in FIG. 2, the upper end of the guide line 124 is connected to the narrowing portion 121 of the large horn 120, and the lower end of the guide line 124 is adjacent to or abutted with the ordinal line 164 of the water main body 161. The guide line 124 is formed with a concave channel 124a along the longitudinal direction so that the water condensed at the catching protrusion 123 of the narrowing passage 121 flows downward along the water channel 124a and flows along the order line 164, Respectively.

The demister filter 130 is mounted in the giant bulb 120 to filter the air passing through the giant bulb 120. When the demister filter 130 is contaminated, the demister filter 130 is installed in the form of a slide on the inner side of the conical bulb 120 so as to facilitate detachment from the conical bulb 120, By attaching the cover, maintenance and convenience of itself are promoted.

The swirl flow mechanism fans 140 and 140 'rotate by the flow pressure of the air exhausted from the horny bulb 120 to swirl the air. Therefore, the air discharged from the horny bulb 120 is dispersed on the inner surface of the water pipe main body 161, so that water remaining in the air condenses on the inner surface of the water pipe main body 161 and remains.

Two or more of the swirling flow mechanism fans 140 and 140 'of this embodiment are arranged in line with the view point of the horny bulb 120. Therefore, the air discharged from the horn-bulb 120 first collides with the closest first mechanism fan 140 and collides with the second subsequent mechanism fan 140 '. Here, the second mechanism fan 140 'has a larger radius than the first mechanism fan 140. Accordingly, the air discharged from the horny bulb 120 is passed through the first mechanism fan 140 and the second mechanism fan 140 'to form a stronger vortex, Thereby increasing the water contact surface on the inner surface of the water main body 161 and promoting the contact speed of the water, thereby improving the penetration speed of the swirling air stream and reducing the static pressure.

The first mechanism fan 140 rotates the wing 141 of the first mechanism fan 140 in the radial direction of the main pipe body 161 in order to reduce the flow velocity of the air discharged from the large- The second mechanism fan 140 'is disposed at a distance of 50 cm or more from the first mechanism fan 140 and the radius of the wing 141' of the second mechanism fan 140 ' The radius of the water main body 161 is set to be 2/3 of the radius. In addition, the swirling flow mechanism fans 140 and 140 'are stably coupled to the pipe 111 via a support bracket 142 that rotatably supports the blades 141 and 141'. For reference, it is preferable to apply a member having a small diameter such as a wire or the like in order to minimize the resistance of the airflow.

The drain pipe 150 collects and drains the water moved along the inner surface of the duct body 110. For this purpose, the duct body 110 may form a drain hole 113 through which the water flowing along the inner surface drains to the outside.

4 is a cross-sectional view schematically showing one embodiment of the drain pipe according to the present invention.

The duct body 110 and the water tube main body 161 are provided at the rear of the swirling flow fan 140 or 140 'so that the water flowing along the inner surface of the duct body 110 is drained. The drain pipe 150 is connected to the outer surface of the duct body 110 so as to communicate with the drain hole 113 and flows into the drain hole 113 to control the drainage of the water collected And a drain valve 153 for discharging the water.

To this end, the drain pipe 150 forms a container-shaped water collecting bowl 151 for receiving water drained from the drain hole 113, and is attached to the outer surface of the duct body 110. The drain pipe 150 may be fastened to the duct main body 110 by welding or by bolting or gluing. In this embodiment, at least one of the front end and the rear end of the drain pipe 150 is provided with a locking protrusion 152, And a fastening means for fastening the duct body 110 along the fastening protrusion 152 with a band or the like is applied. Therefore, the drain pipe 150 of the present embodiment can be directly connected to the existing duct without any additional deformation. Although the drain pipe 150 according to the present embodiment is disposed only on the bottom surface of the pipe 111, the drain pipe 150 may be coupled to at least one of the upper surface, left surface, right surface, and bottom surface of the pipe 111.

Next, the container-shaped drain pipe 150 is provided with a drain valve 153 for controlling drainage of the water drained from the drain hole 113. The drain valve 153 opens and closes the drain pipe P connected to the drain pipe 150 so that the manager can control and manage the drainage of the water collected in the drain pipe 150.

FIG. 5 is a perspective view showing a part of a part of a water pipe in a dehumidifying duct according to the present invention, and FIG. 6 is a sectional view showing a section of a water line section according to the present invention.

The main water pipe main body 161 of the present embodiment is provided with a through hole 162 and a drain hole 162 on the inner surface of the water main body 161 so as to receive the water dropped from the narrow passage 121 of the large- And an order line 164 which is piped toward the discharge pipe 113. Therefore, the water that has fallen on the inner surface of the water pipe main body 161 due to its own weight after being collected in the large-diameter pipe 120 flows along the pipe line of the water line 164 toward the through hole 162 and the drain port 113 . A stopper 163 is protruded from the rear end of the through hole 162 so that water flowing along the order line 164 does not escape to the water pipe 160 via the through hole 162. [ Therefore, the water flowing along the water line 164 flows into the through hole 162 without being separated from the water tank 160, and is discharged through the drain hole 113.

The order line 164 may be a pipe through which one order line 164 guides water to one through hole 162 as shown in FIG. 5, but a plurality of order lines may guide the water through one through hole Or may be a pipe for guiding water through a plurality of through holes. In addition, even if the through holes have a single hole shape, the order lines can be piped in a bottleneck shape so that a plurality of order lines communicate with one drain hole.

The water flowing along the inner surface of the water tube main body 161 flows into the water line 164 and flows through it so that it is not dispersed in the air current generated by the swirling flow fan 140 or 140 ' (113).

On the other hand, the water main body 161 according to the present embodiment is configured such that water generated in a section located on the inner surface of the water tube main body 161 and located behind the swirling flow fan 140 or 140 ' And an order guide 165 installed toward the order line 164 so as to collect the order information.

The swirling flow mechanism fans 140 and 140 'generate swirling flow of air in the water tube main body 161 while being rotated by the wind force of the air exhausted from the large cone tube 120, ) Can be dispersed again. Therefore, the order guide 165 disposed behind the swirling flow mechanism fans 140 and 140 'blocks the flow of the airflow so that the water is not dispersed by the wind force, and the water collected in the order guide 165 reaches its own weight And then flows into the order line 164. Of course, the water introduced into the order line 164 is drained to the through hole 162 and the drain port 113 along the order line 164.

As mentioned above, not much water can be formed on the inner surface of the water tube main body 161, as well as the swirling flow mechanism fans 140 and 140 ', and water formed in this way can form water droplets , And the water line 164 is formed in the section so that the combined water flows toward the through hole 162 and the drain port 113. As a result, the water formed on the inner surface of the water tube main body 161 at the rear of the swirling flow mechanism fans 140 and 140 'is prevented from being evaporated by being pushed backward by the wind force or dispersed again by the wind power, 161 are guided to the through hole 162 and the drain port 113 to collect water.

The present order line 164 is inclined at the bottom surface so that the main water pipe body 161 can flow toward the through hole 162 and the drain port 113 even if the main water pipe body 161 is installed horizontally. In other words, the water flowing into the water line 164 flows along the sloping bottom surface and can flow continuously toward the through hole 162 and the drain port 113.

As a result, the water flowing into the secondary line 164 stably flows toward the through hole 162 and the drain port 113 due to its own weight without detaching the vortex caused by the swirl flow fan 140 or 140 '.

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.
