Description

Dehumidifying duct using swirling-flow to improve dehumidifying efficiency

The present invention is a swirl flow dehumidification method that improves the dehumidification efficiency applicable to weather or season with high humidity so that the effective performance of the deodorizing biooxygen applied to various sewage treatment plants, food treatment plants, horn manure, etc. It is about a duct.

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

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

In the design of the duct, first, the air supply and exhaust hood with proper operation control is designed, and the design flow rate of the air supply and exhaust hood is determined. Second, determine the minimum duct velocity. Since the transfer ducts exhaust particulate matter, a minimum transport velocity must be maintained in the ducts to prevent settling in the transfer ducts. Duct speeds for steam, gas and non-condensable fumes are not critical. Third, the branch duct size is determined by dividing the design flow rate by the minimum duct speed. Select a duct with a slightly smaller inner diameter so that the actual duct speed is greater than the minimum duct speed. Fourth, the schematic diagram is used to determine the required design length for each part of the duct and fittings and elbows. The design length here is the centerline distance along the duct and the radius of the elbow is neglected. Fifth, calculate the pressure loss for the supply and exhaust system. The pressure loss due to friction or fittings can be calculated using the velocity pressure method or the equivalent length method. In this case, the speed pressure method is used more frequently because the speed pressure method is faster, and all losses such as the inflow loss of the hood are calculated by the same criteria. In addition, since the duct is designed by the balanced pressure method, the size of the branch duct can be quickly recalculated.

For reference, the object of dust sucked from the hood has a particle diameter ranging from 0.1 μm to several mm, and the types thereof are various, so that the dust is transported to the prevention facility without being deposited in the duct. The speed of conveying dust is called the conveying speed. The speed of conveying dust depends on the nature of the dust and the pipe condition, but the conveyance speed of heavy metal dust and water wet dust should be increased.

The indoor air conditioning duct described above has a dehumidification function, but in the case of industrial use, a general duct that simply introduces natural outdoor air without a dehumidification function is used. In this case, indoor air drops sharply in winter, affecting certain equipment or sensors to stop the operation of the machine or make the working environment difficult, and the rainy season also increases the discomfort index at the same temperature.

Therefore, if the work environment where odor occurs, the odor removal efficiency can be lowered and the work environment can be lowered. Therefore, a new technology for dehumidifying exhaust or supply air through the duct has been required.

On the other hand, indoor air conditioning plays a role of dehumidification, vibration damping, and temperature maintenance. In particular, even at the same temperature, when the humidity is low, the discomfort index that a human feels is significantly lowered. Therefore, if the humidity of the indoor air can be reduced under the indoor temperature regulation, the above problem can be largely solved. However, dehumidification to reduce humidity at present uses a method of condensing moisture in the air at a low temperature state using a refrigeration cycle, and thus there is a problem that a cooling device must be operated for dehumidification in a general air conditioning system.

This dehumidification is the same in general industrial sites. Therefore, a separate dehumidifier is used to remove water from the water-containing gas, and the dehumidifier is required to cool the gas to increase the saturated steam pressure. Therefore, for dehumidification 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 lowered at least in part, a considerable energy saving effect can be enjoyed.

Dehumidification duct 100 of the present embodiment, the tubular duct body 110, the drain port 113 is formed; It is built in the duct main body 110, the discharge hole 122 is formed in the bottom surface 121a of the narrow passage 121, the horn-shaped tube formed with a locking projection 123 along the tip of the narrow passage 121 120; A water pipe body 161 inserted into the duct body 110 and inserted into the duct body 110 so as to receive water dropped from the narrow body 121 of the horn-large tube 120 and flowably; The through hole 162 perforated in the water pipe body 161 so as to communicate with the drain 113, and the order line 164 piped from the bottom surface of the water pipe body 161 toward the through hole 162. Ordered pipe provided with 160; Swirl flow mechanism fan 140 is installed in a line in the order tube body 161 to face the narrow passage 121 of the horn large tube 120, so that the air passing through the horn large tube 120 rotates to turn , 140 '); It includes; a drain pipe (150) for gathering in the narrow passage 121 of the horn-shaped tube (120) and collects and drains the water flowing down by dropping to the bottom surface of the water pipe body (161).

In addition, the dehumidification duct 100 of the present embodiment, the demister filter 130 is installed in the horn large tube 120 to filter the air flowing toward the narrow passage 121 of the horn large tube 120; It further includes.

Hereinafter, each configuration will be described in more detail.

The duct body 110 is a tube made of a circular curved sheet or a rectangular curved sheet, and the like, and is connected to all ducts such as spiral ducts and square ducts made of aluminum in the form of a kit. The duct main body 110 of the present embodiment may be installed in a section where the pipe diameter of the duct is narrowed to increase the air flow rate, and in the case where there is a branch pipe, it may be installed at the front end of the branch pipe to increase the water removal efficiency. For reference, the duct main body 110 of this embodiment is comprised from the tubular pipe 111 and the flange 112 formed in the edge part of the pipe 111. As shown in FIG. In this case, the flange 112 is utilized for connection with another neighboring water pipe body 161.

The horn-shaped tube 120 forms a tubular shape in which the narrow passage 121 is formed and is installed in the duct body 110. Therefore, the air moving along the duct body 110 is introduced into the horn-shaped tube 120 is discharged through the narrow passage 121. For reference, since the air passing through the narrow passage 121 decreases in temperature as the moving speed increases rapidly, the air is liquefied and discharged from the narrow passage 121. In this process, moisture is collected in the narrow passage 121. . The condensed water forms water droplets and is discharged to the outside of the horn-shaped tube 120 through the narrow passage 121 by receiving the exhaust pressure of the air passing through the narrow passage 121 when it exceeds a certain self weight.

On the other hand, the horn-shaped tube 120 is installed in the duct main body 110, the discharge hole 122 is formed in the bottom surface 121a of the narrow passage 121, the locking projections along the tip of the narrow passage 121 ( 123 is formed. Therefore, the air introduced into the horn large tube 120 is exhausted through the narrow passage 121, causing the vortex while passing through the locking projection 123, during this process water vapor condenses on the front of the locking projection (123) Is generated. As a result, the air passing through the narrow passage 121 undergoes a first dehumidification process, and the generated water falls into the water pipe 160 through the discharge hole 122. For reference, the bottom surface 121a of the narrow passage 121 forms a concave channel so that water condensed from the front surface of the bottom surface 121a and the locking protrusion 123 flows toward the center of the concave channel, and thereby the bottom. Drained to the discharge hole 122 located in the center of one side of the surface (121a).

Subsequently, the horn-large tube 120 of the present embodiment is connected to one end of the discharge hole 122 adjacent to the catching protrusion 123 and suspended in the direction of the order line 164, and is discharged from the discharge hole 122. And a guide line 124 having a concave channel 124a formed along the longitudinal direction so that the drained water flows into the order line 164.

As shown in FIG. 2, the guideline 124 is suspended from the top of the guide line 124 by being connected to the narrow passage 121 of the horn-shaped tube 120, and the bottom of the guideline 124 is adjacent to or in contact with the order line 164 of the body 161. In addition, since the guide line 124 is formed with a concave channel 124a along the longitudinal direction, the water condensed in the locking protrusion 123 of the narrow passage 121 flows downward through the water channel 124a and the order line 164. Flows into.

The demister filter 130 is installed in the horn large tube 120 to filter the air passing through the horn large tube 120. For reference, when the demister filter 130 is contaminated, it is installed in the form of a slide on the inside of the horn large tube 120, so as to be easily removable from the horn large tube 120, on the outer surface of the demister filter 130 By attaching the cover, it maintains its own maintenance and convenience.

Swirl flow mechanism fans 140 and 140 ′ rotate by the flow pressure of the air discharged from the horn-shaped tube 120 to cause the air to turn. Therefore, the air discharged from the horn-shaped pipe 120 is dispersed to the inner surface of the water pipe body 161, and the moisture remaining in the air condenses on the inner surface of the water pipe body 161 and remains.

In the swirl flow mechanism fans 140 and 140 'of this embodiment, two or more are arranged in a line with the horn-shaped tube 120 as a viewpoint. Therefore, the air discharged from the horn-shaped tube 120 collides with the first adjacent first operation fan 140 first, and secondly with the subsequent second operation fan 140 '. Here, the second operation fan 140 ′ of the present embodiment has a larger radius than the first operation fan 140. Therefore, the air discharged from the horn-shaped tube 120 forms a more powerful vortex while passing through the first and second operating fans 140 and 140 ', thereby allowing the airflow to flow through the inner surface of the main body 161. It continuously adjoins with, it produces the effect of increasing the water contact surface of the inner surface of the water pipe body 161 and the contact speed of water, and improving the penetration speed of the turning airflow, and reducing a static pressure.

In this embodiment, the first operating fan 140 has a radius of the wing 141 of the first operating fan 140 to reduce the flow rate of the air discharged from the horn-shaped tube 120. The second operation fan 140 'is disposed at a distance of 50 cm or more from the first operation fan 140, and the radius of the wing 141' of the second operation fan 140 'is different. It is set to 2/3 size of the radius of the water pipe main body 161. In addition, the swirl flow mechanism fans 140 and 140 'are stably engaged with the pipe 111 via a support 142 that rotatably supports the wings 141 and 141'. For reference, the support 142 is preferably to apply a narrow member, such as a wire in order to minimize the resistance of the air flow.

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

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

In more detail, the drain structure of the present embodiment, the duct body 110 and the water pipe body 161 is a drain hole in the rear of the swirl flow mechanism fan (140, 140 ') to drain the water flowing along the inner surface And a through hole 162, respectively, and the drain pipe 150 is fixed to the exterior of the duct main body 110 so as to communicate with the drain hole 113, and controls the drainage of water collected and introduced into the drain hole 113. The drain valve 153 is provided.

To this end, the drain pipe 150 constitutes a container-shaped collecting bowl 151 for receiving water drained from the drain hole 113, and is bound to the outer surface of the duct body 110. The binding of the drain pipe 150 to the duct body 110 may be a fastening means such as welding or bolting or bonding, but in the present embodiment, the drain pipe 150 may be fastened to at least one of the front end and the rear end. Forming, to apply a fastening means for wrapping and tightening the duct body 110 along the locking step 152 with a band or the like. Therefore, the drain pipe 150 of the present embodiment can be directly attached without additional modification to the existing duct. For reference, although the drain pipe 150 of the present embodiment is disposed only on the bottom surface of the pipe 111, the drain pipe 150 may be formed by binding to one or more of the top, left, right and bottom surfaces of the pipe 111.

Subsequently, the container-shaped drain pipe 150 includes a drain valve 153 for controlling the drainage of the water drained from the drain port 113 and collected. Here, the drain valve 153 opens and closes the drain pipe P connected to the drain pipe 150, and the manager may control and manage the drainage of the water collected in the drain pipe 150.

Figure 5 is a perspective view showing a cross-sectional view of one embodiment of the water pipe in the dehumidification duct according to the present invention, Figure 6 is a cross-sectional view showing a cross-sectional view of the order line section in accordance with the present invention.

The water pipe main body 161 of the present embodiment has a through hole 162 and a drainage hole at an inner surface of the water pipe main body 161 so as to receive water that has fallen from the narrow passage 121 of the horn-large tube 120 to be flowable. The order line 164 is piped toward the 113. Accordingly, the water that is concentrated in the horn-shaped pipe 120 and dropped to the inner surface of the water pipe body 161 by its own weight flows toward the through hole 162 and the drain 113 along the pipe path of the water line 164. . For reference, a stopper 163 is formed at the rear end of the through hole 162 so that the water flowing along the order line 164 does not leave the water line 160 through the through hole 162. Accordingly, the water flowing along the order line 164 flows into the through hole 162 without leaving the order pipe 160 and is discharged through the drain hole 113.

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

Through this, the water flowing along the inner surface of the water pipe body 161 flows into and flows into the water line 164, so that the through-hole 162 and the drain hole are not dispersed even in the air flow generated by the swirl flow mechanism fans 140 and 140 '. It can flow stably toward 113.

On the other hand, the water line main body 161 of the present embodiment, the water line generated in the section located behind the swirl flow mechanism fans 140, 140 'on the inner surface of the water line main body 161 as shown in FIG. In order to be collected by the), the order guide 165 is further provided toward the order line 164 is further provided.

The swirling flow mechanism fans 140 and 140 'rotate by the wind power of the air exhausted from the horn-shaped tube 120 to cause the swirling flow of air in the order pipe body 161. The swirling flow is the order pipe body 161. The water collected on the inner surface of the can be dispersed again. Therefore, the order guide 165 disposed behind the swirl flow mechanism fans 140 and 140 ′ blocks the flow of air so that water dispersion by wind does not occur, and the water collected in the order guide 165 is self-weighted. It flows downward by the flow into the order line (164). Of course, water introduced into the order line 164 is drained to the through hole 162 and the drain 113 along the order line 164.

As mentioned above, a considerable amount of water may be formed on the inner surface of the water flow pipe main body 161 as well as the swirling flow mechanism fans 140 and 140 ', and the water thus formed may form water droplets while being combined with each other. The order line 164 is formed in the section so that the combined water flows toward the through hole 162 and the drain hole 113. As a result, the water formed on the inner surface of the water pipe body 161 at the rear of the swirl flow mechanism fans 140 and 140 'is prevented from being pushed backward by the wind or dispersed again by the wind and vaporizing. 161 and guides the water settled on the inner surface to the through hole 162 and the drain 113 to collect.

In addition, the order line 164 of the present embodiment is formed so that the bottom surface is inclined so as to flow toward the through hole 162 and the drain port 113 even when the water pipe body 161 is horizontally installed. That is, the water flowing into the order line 164 is allowed to flow continuously along the inclined bottom surface toward the through hole 162 and the drain 113.

As a result, the water flowing into the order line 164 stably flows toward the through hole 162 and the drain 113 by its own weight without being separated from the vortices caused by the swirl flow mechanism fans 140 and 140 '.
