Description

Technical Field

[0001] The invention relates to the technical field of spray cooling, and in particular to a plant spray cooling system. Background Art

[0002] During the hot summer season, the temperature in the production plant can reach above 35°C, and for the steel structure production site, most of the workers are using welding machines for welding. The high temperature generated during welding plus the original high temperature of the weather have a severe impact on the workers' physiology and working environment, which can easily cause heat stroke in workers and seriously affect the health and production efficiency of personnel; the Chinese patent with announcement number CN209147323U discloses a plant temperature control spray circulation system, which sprays and cools the roof by setting a sprinkler nozzle on the outer roof, and the residual water after spraying can be recycled and reused; this prior art has at least two defects: first, spraying in an open environment outside the roof, not only will the flowing air take away a lot of moisture, but the spray water will also cover the entire roof, which also requires a lot of water, consumes a lot of water resources, and also increases the burden of water circulation; second, the sprinkler head and the water pipe structure are exposed outside the roof, and are affected by relatively bad weather such as rain, snow and strong wind, which will greatly reduce the service life, require frequent maintenance, and increase the cost of use. Summary of the invention

[0003] In order to overcome the deficiencies in the background technology and solve the existing technical problems, the present invention discloses a plant spray cooling system, which can not only achieve better cooling effect with less resource consumption, but also reduce maintenance costs.

[0004] In order to achieve the above-mentioned invention object, the present invention adopts the following technical scheme: A factory building spray cooling system comprises a return water bucket, a water storage bucket, a high-pressure water pump and a building body with a double-slope roof, wherein a human-shaped ceiling which can be controlled to rise and fall and position by a lifting mechanism is correspondingly arranged directly above the double-slope roof; water-collecting curtains are installed on both side edges of the human-shaped ceiling, and a water collecting trough is provided directly below each water-collecting curtain, and both water collecting troughs are lower than the bottom of the double-slope roof and are fixed to the corresponding outer side walls of the building body, and the bottom of the water collecting trough is correspondingly connected to the return water bucket through a return water pipe; an atomizing nozzle for spraying upwards is installed on the top of the double-slope roof, and the water inlet end of the atomizing nozzle is correspondingly connected to the outlet of the high-pressure water pump through a high-pressure hose, and the inlet of the high-pressure water pump is correspondingly connected to the water storage bucket.

[0005] Furthermore, the lifting mechanism includes two rows of telescopic cylinders respectively arranged on both sides of the room body, the cylinder body of the telescopic cylinder is fixed to the inner wall of the room body, and the telescopic rod end of the telescopic cylinder slides and seals through the double-slope roof and is fixedly connected to the human-shaped ceiling.

[0006] Furthermore, the water-collecting curtain comprises a frame, a frame edge of which is rotatably connected to a corresponding side edge of the human-shaped ceiling, and a metal mesh or a plurality of evenly spaced metal baffles are arranged in the frame.

[0007] Furthermore, the cross section and longitudinal body of the water collecting trough are both V-shaped, and the upper end of the return pipe is connected to the lowest point of the bottom surface of the water collecting trough.

[0008] Furthermore, a holder is provided at the tail end of the atomizing nozzle for detachable connection with the top of the double-slope roof.

[0009] Furthermore, a T-shaped guide rail along the longitudinal direction of the double-slope roof is fixed to the top of the double-slope roof, and the holder of the atomizing nozzle is clamped on the T-shaped guide rail and can be controlled by a driving mechanism to move and position along the T-shaped guide rail.

[0010] Furthermore, a plurality of atomizing nozzles are evenly spaced longitudinally along the double-slope roof.

[0011] Furthermore, filtering devices are provided at both ends of the return pipe.

[0012] Furthermore, a circulation pipe with a circulation pump is connected between the return water bucket and the water storage bucket, and temperature measuring devices are provided in the return water bucket and the room body.

[0013] Furthermore, a refrigeration device for cooling the return water in the return water barrel is provided on one side of the return water barrel.

[0014] Due to the adoption of the above-mentioned technical solution, the present invention has the following beneficial effects: The factory building spray cooling system disclosed in the present invention can form a mezzanine space between the human-shaped ceiling and the double-broken roof by adding a human-shaped ceiling, so as to block the downward transmission of sunlight heat and protect the atomizing nozzle and the pipeline. After the atomizing nozzle sprays the water in the water storage barrel upward into atomized form, it can first spray it on the middle part of the human-shaped ceiling. The water on the human-shaped ceiling flows and spreads from the middle to both sides along the slope to form a cooling water film. The water droplets atomized by the atomizing nozzle and reflected by the human-shaped ceiling and floating in the mezzanine space form a cooling fog area, and the water falling on the double-slope roof will also form a cooling water film, thereby greatly improving the effect of spray cooling; at the same time, under the protection of the human-shaped ceiling and the water-collecting curtain, a large amount of water loss can be prevented, and it is ensured that the return water can be recycled and reused through the water collection tank, thereby greatly reducing the consumption of water resources; more importantly, the human-shaped ceiling is designed to be liftable to meet the use requirements of different weather changes.

A human-shaped ceiling 2 which can be lifted and positioned by a lifting mechanism is arranged directly above the double-slope roof 1. The width of the human-shaped ceiling 2 is slightly larger than the double-slope roof 1, but the shape is consistent from top to bottom, which is convenient for water flow diffusion and can be closer to the double-slope roof 1 when the human-shaped ceiling 2 is lowered. The human-shaped ceiling 2 can generally be made of lightweight materials for easy lifting and lowering control. When spray cooling is not needed in spring, autumn and winter, it can be lowered and retracted to avoid damage by strong winds or snow. In addition, the lifting mechanism of the human-shaped ceiling 2 is Lowering the height also affects the spray reflection of the atomizing nozzle 4. When the height is low, the water mist space is small and the water flow recovery circulation speed is fast. According to the needs, the lifting mechanism includes two rows of telescopic cylinders 5 respectively arranged on both sides of the room body. The cylinder body of the telescopic cylinder 5 is fixed to the inner wall of the room body. After the end of the telescopic rod of the telescopic cylinder 5 slides and seals through the double-slope roof 1, it is fixedly connected to the human-shaped ceiling 2. The human-shaped ceiling 2 is lifted and lowered by controlling the telescopic cylinder 5 to extend and retract. Specifically, a plurality of telescopic cylinders 5 in each row can be evenly spaced according to the supporting weight, and a sealing ring is installed in the hole through which the telescopic rod of the telescopic cylinder 5 passes to ensure the sealing effect and prevent water leakage. Water-collecting curtains 3 are installed on the two side edges of the human-shaped ceiling 2. The water-collecting curtains 3 can play a protective role and prevent water mist from excessively overflowing, thereby losing a large amount of water. When the water mist hits the water-collecting curtains 3, it can be collected and flow downward; the water-collecting curtains 3 can be set as generally dispersed flexible curtains, and can also be set as needed to include a frame, one frame edge of the frame is correspondingly connected to the corresponding side edge of the human-shaped ceiling 2 for rotation, and a metal mesh or a plurality of evenly spaced metal baffles are arranged in the frame, which is convenient for the overall rotation and flipping up without affecting the descent of the human-shaped ceiling 2, and can also play a role in condensing water when it droops; a water collection tank 6 is provided directly below each water-collecting curtain 3, The two water collecting tanks 6 are both lower than the bottom of the double-slope roof 1 and fixed to the outer side wall of the corresponding house body, so that the water collecting tank 6 can recover the water dripping from the water collecting curtain 3 and the water from the double-slope roof 1; the bottom of the water collecting tank 6 is connected to the return water bucket 14 through the return water pipe 8, so that the water collected by the water collecting tank 6 can flow into the return water bucket 14 through the return water pipe 8; according to the needs, the cross section and the longitudinal groove body of the water collecting tank 6 are both V-shaped, that is, there will be a low point position in the center of the groove bottom of the water collecting tank 6, and the upper end of the return water pipe 8 is connected to the low point position of the groove bottom surface of the water collecting tank 6, so as to facilitate complete water return; in addition, both ends of the return water pipe 8 are provided with filtering devices 12 to prevent mud and debris from entering the return water pipe 8; The top of the double-slope roof 1 is equipped with an atomizing nozzle 4 that sprays upward. The atomizing nozzle 4 can atomize and spray the water sent up to a certain extent, thereby achieving a better heat exchange and cooling effect. When the atomizing nozzle 4 is fixedly installed, it is necessary to provide a plurality of atomizing nozzles 4 evenly spaced along the longitudinal direction of the double-slope roof 2, so that the spray covers the entire double-slope roof 1; according to needs, the tail end of the atomizing nozzle 4 is provided with a holder that is detachably connected to the top of the double-slope roof 1, and the atomizing nozzle 4 can be removed in seasons when spraying and cooling are not required; in addition, in order to save costs and reduce the disassembly and assembly process, only one atomizing nozzle 4 can be installed, and the top of the matching double-slope roof 1 is fixed with a T-shaped guide rail along the longitudinal direction of the double-slope roof 1, and the holder of the atomizing nozzle 4 is clamped on the T-shaped guide rail and can be driven The mechanism controls the movement and positioning along the T-shaped guide rail, and the driving movement is a prior art and will not be described in detail. The hose connected to the atomizing nozzle 4 does not affect its movement. The water inlet end of the atomizing nozzle 4 is connected to the outlet of the high-pressure water pump 9 through the high-pressure hose 7, and the inlet of the high-pressure water pump 9 is connected to the water storage barrel 11. The water in the water storage barrel 11 is sent to the atomizing nozzle 4 for spraying through the high-pressure water pump 9. According to needs, a circulation pipe 10 with a circulation pump 13 is connected between the return water barrel 14 and the water storage barrel 11 to facilitate the recycling of water flow. The return water barrel 14 and the room body are both provided with temperature measuring devices, which can adjust the spray water flow rate according to the detected temperature. In addition, a refrigeration device 15 for cooling the return water in the return water barrel is provided on one side of the return water barrel 14, and the cooling effect can be further improved by refrigeration.

[0018] The factory building spray cooling system described in the present invention is implemented. When spray cooling is needed, it is only necessary to first control the telescopic cylinder 5 to lift the double-slope roof 2 to a certain height, and then start the high-pressure water pump 9 to send the water in the water storage barrel 11 upward to the atomizing nozzle 4 for spraying. The sprayed water mist is diffused through divergence and reflection to achieve a local cooling effect. At the same time, excess water flows into the water collection tank 6 and is then collected into the return bucket 14 for standby use. When spraying is not needed, the double-slope roof 2 can be lowered and retracted by the telescopic cylinder 5.
