Description

Technical Field

[0001] The invention relates to the technical field of cooling tower spraying, in particular to a counter-spraying mechanism for a cooling tower. Background Art

[0002] The water spraying system of the cooling tower is one of the important components. It cooperates with the spraying filling mechanism to undertake most of the cooling tasks in the cooling tower. The effect of the water spraying system directly affects the cooling efficiency of the cooling tower. The current spraying mechanism is mostly designed at the upper end of the spraying filling mechanism. The upper opening of the spraying filling mechanism is sprayed by rotating the spraying method, and then the upper opening and the air inside are cooled, resulting in a large amount of kinetic energy loss. At the same time, the spraying is not direct enough, and the upper exhaust port cannot be fully covered. Moreover, the spraying effect cannot be automatically controlled according to the air temperature. The degree of automation control is low, and it cannot be quickly stored and adjusted to change the spraying method. Later maintenance is also more troublesome. Summary of the invention

[0003] The technical problem to be solved by the present invention is: the current spraying mechanism is mostly designed at the upper end of the spraying filling mechanism, and spraying is carried out by rotation, which leads to a large amount of kinetic energy loss. The spraying is not direct enough and cannot fully cover the upper exhaust port. Moreover, the spraying effect cannot be automatically controlled according to the air temperature. The degree of automatic control is low, and it cannot be quickly stored and adjusted to change the spraying mode. Later maintenance is also more troublesome.

[0005] The opposite spraying mechanism includes a transverse guide pipe fixedly installed on both sides of the upper end opening of the spray filler, a side-mounted electrically controlled adjustment support rod for controlling the flipping of the transverse guide pipe, a first spray head installed on the outer wall of one side of the transverse guide pipe, a second spray head installed on the outer wall of the other side of the transverse guide pipe, a first sputtering cover plate elastically mounted on the outer wall of one side of the transverse guide pipe, and a second sputtering cover plate elastically mounted on the outer wall of the other side of the transverse guide pipe.

[0006] The first spray head and the second spray head are staggeredly arranged on both sides of the transverse flow guide pipe.

[0010] A temperature sensing and control module is fixedly assembled on the outer side surfaces of the first sputtering cover plate and the second sputtering cover plate.

[0011] Lateral limiting blocks are provided on the side wall of the cooling tower body and are matched with the first sputtering cover plate and the second sputtering cover plate.

[0012] Condensation plates are installed on both the outer side surface and the lower end of the fixed bracket.

[0013] The bottom return pump is fixedly installed on the inner side wall of the bottom water collection box, and an electrically controlled rotary filter screen is movably sleeved outside the lateral inlet of the bottom return pump.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, and therefore only showing the components related to the present invention.

[0022] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An opposed jet spraying mechanism for a cooling tower as shown in and, including a cooling tower body 1, a spraying filler 2 is fixedly installed inside the cooling tower body 1, an opposed jet spraying mechanism 3 is fixedly assembled above the spraying filler 2 inside the cooling tower body 1, a top-mounted diversion mechanism 4 is installed on the inner top surface of the cooling tower body 1, a bottom-mounted reflux assembly 5 is fixedly assembled at the lower end of the cooling tower body 1, a bottom-mounted reflux pump 6 is fixedly installed on one side inside the bottom-mounted reflux assembly 5, and a side-mounted diversion pipe 7 communicating with the opposed jet spraying mechanism 3 is installed on the side wall of the bottom-mounted reflux pump 6.

[0024] Working principle: air is introduced from the bottom of the cooling tower body 1, then passes through the spray filler 2, and then the bottom reflux pump 6 is started, and the coolant inside the bottom reflux component 5 is filled into the inside of the opposite spray mechanism 3 through the side-mounted guide pipe 7, and the opposite spray mechanism 3 is used to spray the upper opening position of the spray filler 2, thereby improving the cooling effect, and the cooled air is upward and discharged to the outside of the cooling tower body 1 by the top guide mechanism 4.

[0025] In order to cooperate with the top spraying, the double-spray spray mechanism 3 includes a horizontal guide tube 31 fixedly installed on both sides of the upper end opening of the spray filler 2, a side-mounted electrically controlled adjustment support rod 32 for controlling the flipping of the horizontal guide tube 31, a first spray head 33 installed on the outer wall of one side of the horizontal guide tube 31, a second spray head 34 installed on the outer wall of the other side of the horizontal guide tube 31, a first sputtering cover plate 35 elastically mounted on the outer wall of one side of the horizontal guide tube 31, and a second sputtering cover plate 36 elastically mounted on the outer wall of the other side of the horizontal guide tube 31.

[0026] The transverse flow guide pipe 31 is movably assembled with the shaft pipes on both sides and the upper end discharge pipe of the side-mounted flow guide pipe 7, so that the connection state can be ensured and the flow guide pipe 31 can be turned over and adjusted.

[0027] The bottom-mounted reflux pump 6 injects liquid into the interior of the horizontal guide tube 31 through the side-mounted guide tube 7, and then uses the first spray head 33 to spray water outward to the inner wall of the first sputtering cover plate 35, controlling the first sputtering cover plate 35 to be squeezed and flipped upward, thereby forming a sputtering spray effect obliquely downward; similarly, the second spray head 34 sputters and sprays from the inside to the inner wall of the second sputtering cover plate 46.

[0028] In order to ensure the spraying range of the internal gap of the transverse flow guide tube 31 , the first spray head 33 and the second spray head 34 are staggeredly arranged on both sides of the transverse flow guide tube 31 .

[0029] In order to cooperate with the top exhaust, a top exhaust port 8 is opened on the top surface of the cooling tower body 1, and the top guide mechanism 4 is installed at the air inlet position at the lower end of the top exhaust port 8 through a fixing bracket 9.

[0030] In order to cooperate with the bottom liquid collection and filtration, the bottom reflux assembly 5 includes a bottom water collection box 10 fixed to the lower end of the cooling tower body 1, a top water inlet opened at the upper end of the bottom water collection box 10 and a metal filter 11 fixed inside the top water inlet.

[0031] In order to increase the spraying range, the first spray head 33 and the second spray head 34 are designed to be staggered in the horizontal and vertical directions.

[0032] The horizontal misalignment of the first spray head 33 and the second spray head 34 is to increase the spray range, while the vertical misalignment of the first spray head 33 and the second spray head 34 is used to control the flipping of the first sputtering cover plate 35 and the second sputtering cover plate 36 to different heights.

[0033] To cooperate with the temperature control adjustment, a temperature sensing control module 12 is fixedly assembled on the outer sides of the first sputtering cover plate 35 and the second sputtering cover plate 36.

[0034] The temperature sensing control module 12 monitors the temperatures on the outer sides of the first sputtering cover plate 35 and the second sputtering cover plate 36, and adjusts the flow rates of the first spray head 33 and the second spray head 34 according to the temperature levels, so as to achieve the purpose of intelligent temperature control.

[0035] The bottom-mounted reflux pump 6 and the side-mounted diversion pipe 7 adopt two sets of systems, one for supplying liquid to the first spray head 33 and the other for supplying liquid to the second spray head 34.

[0036] To prevent the first sputtering cover plate 35 and the second sputtering cover plate 36 from flipping too much, lateral limit blocks 13 that cooperate with the first sputtering cover plate 35 and the second sputtering cover plate 36 are provided on the side wall of the cooling tower body 1.

[0037] When the side-mounted electric control adjusting strut 32 controls the horizontal diversion pipe 31 to flip upward by contraction, at this time, the lateral limit block 13 is inserted into the inner gap of the horizontal diversion pipe 31 to limit the maximum flipping angle of the first sputtering cover plate 35 and the second sputtering cover plate 36, so as to prevent the sputtering range from being excessive due to excessive water pressure, thus affecting the spray effect and angle.

[0038] To improve the top condensation reflux, condensation plates 14 are installed on the outer side and the lower end of the fixing bracket 9.

[0039] When the relatively humid air is being pumped outwards, it will also be blocked by the condensation plate 14, retaining the moisture inside on the condensation plate 14, and then falling back into the bottom-mounted water collecting box 10 at the bottom, thereby improving the water resource recycling utilization rate.

[0040] To cooperate with the filtration of the water pumping port and prevent blockage, the bottom-mounted reflux pump 6 is fixedly installed on the inner side wall of the bottom-mounted water collecting box 10, and an electric control rotating filter net 15 is movably sleeved outside the lateral inlet of the bottom-mounted reflux pump 6.

[0041] The electric control rotating filter net 15 includes an annular guide rail fixed outside the lateral inlet of the bottom-mounted reflux pump 6, an external adjustment cover movably sleeved outside the annular guide rail, a cylindrical filter net fixed outside the external adjustment cover, and an embedded motor for adjusting the rotation of the external adjustment cover. The embedded motor is fixed on the outer side of the bottom-mounted reflux pump 6 and drives the external adjustment cover to rotate along the annular guide rail through the gear on the drive shaft.

[0042] Inspired by the above-described ideal embodiments of the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of the present invention. The technical scope of the present invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
