Description

Technical Field

[0001] The utility model relates to a spray room, in particular to a low-resistance parallel tube group textile air-conditioning spray room. Background Art

[0002] The production process of textile factories requires a reasonable air-conditioning environment to ensure the quality of products and the health of workers. Therefore, textile factories need to meet the workshop temperature, humidity, air freshness and cleanliness required by the process. The temperature and humidity regulation of traditional textile air-conditioning systems generally adopts the treatment method of direct water spraying and direct air heat and moisture exchange. Chilled water or deep well water is pumped through the pipeline to increase the pressure and then enter the nozzle for atomization. The air is cooled, dehumidified or humidified by spraying with single or double rows of pipes. For the textile industry, the temperature and humidity of the workshop process can be controlled by simple water and air heat and moisture exchange. With the gradual improvement of the automation control means of textile air-conditioning, although the traditional water spray air-conditioning system has been widely used, it also has obvious shortcomings. The main problems are:

[0003] The water output of the sprinkler system pump and the water output of the nozzle are designed to match each other. At present, the water volume and air volume are both involved in automatic frequency conversion adjustment when the air conditioner is automatically adjusted. Since the water pump is operated with variable frequency, the water volume and pressure of the water pump change at any time, which will affect the atomization angle of the nozzle. The original nozzle spray angles are intersecting with each other, and there will be gaps in the closed water curtain. When the air flows, this space does not produce heat and moisture exchange, resulting in low heat and moisture exchange efficiency. Especially when the water pump pressure is low, some nozzles on the spray chamber do not spray water, and the air does not get a thorough heat and moisture exchange, making it difficult to guarantee the air temperature, humidity and cleanliness in the workshop. This not only wastes energy, but also affects production and endangers the health of workers.

[0004] Conventional nozzle arrangement in the prior art is as follows Figure 1 As shown, in the figure, 1-1 is the water supply main, 1-2 is the drainage branch pipe, 1-3 is the nozzle connecting short pipe, 1-4 is the centrifugal nozzle and 1-5 is the installation fixing bracket;

[0005] In the spray room, one or more main water supply pipes are connected to multiple spray branch pipes 1-1. Spray branch pipes 1-2 are installed vertically above the water surface. Each spray branch pipe has a short nozzle connection pipe 1-3, which facilitates connection to nozzles 1-4. The nozzles also have a threaded short pipe for connecting the nozzles. As shown in the figure, the short nozzle connection pipes increase the pressure on the water pump, resulting in high energy consumption. Furthermore, an air-conditioning spray room has many branch pipes, equipped with hundreds to thousands of nozzle connection pipes and nozzles. When air is supplied, these spray branch pipes, nozzle connection pipes, and nozzles occupy a large area of ​​the heat and moisture exchange space, resulting in significant wind resistance. Furthermore, the water atomized by the nozzles in the first row of spray pipes collides with the nozzle connection pipes and nozzles in the second row of pipes, forming water droplets, which affect the heat and moisture exchange effect. The nozzle connection pipes and nozzles are also prone to catching small cotton and dust particles, which also affect the heat and moisture exchange effect. Since the number of spray water pumps and nozzles is matched, when the air conditioning automatic control system automatically adjusts the frequency of the water pump, the water volume and pressure of the water pump will drop at the same time, and it will not be possible to provide many nozzles to spray at the same time, resulting in low efficiency and waste of energy.

DETAILED DESCRIPTION

[0031] The following describes a low-resistance parallel tube group textile air-conditioning spray room of the present invention in conjunction with the accompanying drawings.

[0032] In Example 1 of the present application, Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 and Figure 9As shown, the utility model is a low-resistance parallel tube group textile air-conditioning spray room, including a water pool 12, in which an overflow pipe 9, a water filter 10 and a drain pipe 11 are provided. The water pool 12 is connected to a water pump 8 through a water supply pipe 8-1, and the water pump 8 is connected to a spray main pipe 7 in the spray room 1. The surface of the spray main pipe 7 is arranged in pairs of spray pipe groups 1 7-1 and spray pipe groups 2 7-2 that are parallel to each other. The surface of the spray pipe group 1 7-1 is connected to one end of a plurality of parallel airfoil-shaped forward spray pipes 2-1, and the surface of the spray pipe group 2 7-2 is connected to one end of a plurality of parallel airfoil-shaped reverse spray pipes 2-2.

Compared with conventional drainage pipes, the low-resistance drainage pipes with built-in nozzles mainly reduce the short connecting pipes of the nozzles, reduce the resistance loss of the water pump, and combine the nozzles and drainage pipes internally, reducing the wind resistance facing the nozzles and reducing the resistance loss of the fan.

[0033] The structure of the second embodiment is basically the same as that of the first embodiment, except that Figure 6 、 Figure 7 and Figure 10 As shown, the surface of the spray pipe group 1 7-1 is connected to one end of multiple olive-shaped spray pipes Ⅰ2-3 arranged in parallel, and the surface of the spray pipe group 2 7-2 is connected to one end of multiple olive-shaped spray pipes Ⅱ2-4 arranged in parallel, and nozzles 3 are installed on the opposite side of the olive-shaped spray pipes Ⅰ2-3 and the olive-shaped spray pipes Ⅱ2-4.

[0034] Compared with the commonly used circular sprinkler pipes at present, under the condition of the same height cross-section, the cross-sectional area increases after using special-shaped pipes, the water flow velocity can be reduced, and the resistance of the water pump is reduced; compared with the commonly used circular sprinkler pipes at present, under the condition of the same water flow velocity, the height cross-sectional area of ​​the pipe can be reduced after using special-shaped pipes, and the wind resistance can be reduced.

Figures 11 to 15 As shown, the spray main pipe 7, located near the water filter 10, is connected to a plurality of parallel, airfoil-shaped, sequential spray pipes 2-1 via a vertical pipeline. Behind the airfoil-shaped sequential spray pipes 2-1, the spray main pipe 7 is connected to two sets of opposing horseshoe-shaped spray pipes 2-5 via pipelines. The nozzles 3 are mounted in recessed grooves at equal intervals on the opposing sides of the two sets of horseshoe-shaped spray pipes 2-5.

[0036] In order to further improve the performance of the present invention and prevent water mist from entering the factory, a water baffle 4 is provided at the air outlet of the spray chamber 1. A guide plate is provided at the air inlet of the spray chamber 1, which can effectively rectify the air, reduce air resistance, and improve the efficiency of air heat and moisture exchange.

[0037] Olive-shaped spray pipes I2-3 and II2-4 can be installed on the same cross-section as the guide plate, achieving a single flow and spray system. This increases the spray chamber length and reduces resistance within the air straightener and pipe system. To further improve air flow efficiency and extend equipment life, aerofoil-shaped forward spray pipes 2-1, aerofoil-shaped reverse spray pipes 2-2, olive-shaped spray pipes I2-3, and II2-4 are constructed from steel, plastic, or stainless steel.
