Description

Technical Field

[0001] The invention relates to a cooling tower, in particular to an intelligent electricity-free cooling tower with high efficiency, durability and ultra-low noise. Background Art

[0002] The electricity-free cooling tower is a cooling tower that does not use electricity. Compared with the traditional cooling tower, its energy-saving and power-saving technology is mainly reflected in the fact that it does not use a motor to drive the fan blades, completely eliminating the need for a motor device. The cooling tower fan blades are driven by a water machine. The principle is to convert the amount of water flow into the mass of the air that is pushed to exchange heat with the hot water. The motor uses a certain number of kilowatts of electrical power to convert the mass of the air that is pushed to exchange heat. This simply means that the shaft power of the water machine of the motor-free cooling tower is the same as the shaft power of the motor, and the same cooling effect can be achieved. The shape, structure, size, and cooling principle of the cooling tower do not need to be changed.

[0003] The turbines used in the current electricity-free cooling towers will produce a lot of noise during use, and the water flow in the internal cooling cycle will also produce a certain amount of noise. The current sound insulation method uses sound insulation materials to fit the inner and outer surfaces of the tower body. This type of sound insulation material is relatively loose and can easily breed bacteria in a humid environment, causing discoloration of the material surface and certain pollution.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figures 1 to 5 In an embodiment of the present invention, an efficient, durable, ultra-low noise intelligent electricity-free cooling tower includes a cooling tower case 1, the main body of the cooling tower case 1 is a rectangular parallelepiped structure, air intake windows 21 are opened at the left and right ends of the cooling tower case 1, an exhaust port is opened at the middle position of the top of the cooling tower case 1, and a silencing chamber 12 is arranged in the exhaust port and the corresponding cooling tower case 1, the silencing chamber 12 is connected to the inner wall of the cooling tower case 1 through a bracket, the silencing chamber 12 is a cylindrical structure with an opening at the top, and a plurality of through holes are opened on the outer surface and the bottom of the silencing chamber 12, so that the sound emitted by the sound source in the silencing chamber 12 can be partially weakened by reflection from the inner wall, and partially weakened by interference through the through holes, and the space between the silencing chamber 12 and the cooling tower case 1 can be used to reduce the sound again, thereby meeting the requirement of ultra-low noise.

[0029] The top of the exhaust hole of the cooling tower housing 1 is covered with a cover 15 with holes.

[0030] A limiting pipe 13 is welded at the exhaust hole of the cooling tower box 1, and an annular plate is welded at the bottom of the limiting pipe 13, and the inner ring of the annular plate is connected to the middle outer surface of the soundproof chamber 12 through a sealing ring, and a flange welded on the outside of the top opening of the soundproof chamber 12 is fixedly connected to the top of the limiting pipe 13; the soundproof chamber 12 is divided into an upper half and a lower half by the limiting pipe 13, and an electricity-free water equalization mechanism is arranged in the upper half of the soundproof chamber 12, so that in the actual working process, the turbine drives the airflow to rise and can inhale air from the lower half of the soundproof chamber 12, thereby extending the working distance of the airflow and avoiding the problem of uneven cooling caused by air intake from the through holes in the upper half. At the same time, the setting of the limiting pipe 13 is equivalent to adding a structure that reflects and consumes sound waves, thereby further reducing the noise generated in the area where the turbine is located.

[0031] The electricity-free water-equalizing mechanism is mainly composed of a plurality of turbines 16, the output shafts of the turbines 16 are fixedly connected to the fan blades for exhaust, the water inlet end of one of the turbines 16 is connected to the external hot water discharge system through an inlet pipe, and the discharge end of the turbine 16 is connected to an input port of a multi-way pipe 18 and the water inlet end of another turbine 16 through a corresponding electromagnetic three-way valve 19, thereby realizing the series connection of multiple turbines, and at the same time, the output end of the last turbine is directly connected to the last input port of the multi-way pipe 18; the output end of the multi-way pipe 18 is connected to the water distribution network 17 through a pipeline, and in actual use, different numbers of turbines are operated by sequentially controlling the conduction cycle of the electromagnetic three-way valve 19, thereby realizing the selection of different exhaust volumes, that is, the kinetic energy of the water discharged from the hot water discharge system is reasonably utilized to achieve heat dissipation and increase the energy consumption mode (mainly the kinetic energy of the water discharged from the hot water discharge system).

[0032] The electromagnetic three-way valve 19 is located in a waterproof sealing box, which is fixed to the corresponding metal pipe by welding. At the same time, the inlet and outlet holes of the waterproof sealing box are both provided with waterproof plugs. The turbine 16 is fixedly connected to the inner wall of the anechoic chamber 12 by a bracket.

[0033] The water inlet pipe is connected with an electronic pressure gauge 20, which is used to detect the water pressure of the high-temperature inlet water, that is, to determine its driving pressure according to the model of the selected turbine 16, that is, the size of the inlet water pressure determines how many turbines 16 participate in the work, and the electronic pressure gauge 20 collects the signal and sends it to the controller, and the PLC in the controller calculates (when the detected pressure is greater than the pressure required by a turbine 16, a solenoid three-way valve is adjusted after the fixed pressure is subtracted in sequence, until the remainder is less than the pressure required by a turbine 16, and then stops), and then controls the solenoid three-way valve 19 by outputting the level. In the actual use process, the solenoid three-way valve 19 needs to be numbered 1, 2, 3, 4...N from the water inlet side to the water outlet side, and the opening logic of the controller is to open from the small number to the large number in sequence, and the closing logic is to close from the large number to the small number in sequence. In fact, when there is no opening, the controller detects the water pressure of the inlet water and first opens the solenoid three-way valve numbered 1, and then opens the remaining solenoid valves in sequence after the pressure stabilizes.

[0034] A water collecting trough 11 is welded on the bottom inner wall of the cooling tower box 1 corresponding to the bottom of the anechoic chamber 12, which is used to collect the cooling water sprayed by the electricity-free water equalization mechanism. A drain outlet is opened at the bottom of the cooling tower box 1 corresponding to the water collecting trough 11, and one end of the bellows 8 is connected to the drain outlet, and the other end of the bellows 8 is connected to one end of the movable joint 9 (the bellows is made of plastic material, which can effectively reduce the sound of water impact). The movable joint 9 is tubular and has a retaining ring 10 welded on the surface. The other end of the movable joint 9 is inserted into the water inlet of the water collecting box 7, and the movable joint is used to achieve seamless drainage docking to prevent the sound of leaking water from being transmitted to the outside, thereby further reducing the drainage noise.

[0035] The joint below the retaining ring 10 is used to movably connect the semicircular ring welded at one end of the lever 6. The middle part of the lever 6 is rotatably connected to the support leg below the cooling tower box 1 through a rotating shaft welded thereon, so that the movable joint can be manually opened as needed.

[0036] An air filter structure is provided between the air inlet window of the cooling tower box 1 and the water collecting tank 11. The air filter structure is mainly composed of a movable air balancing plate 2, a wire brush 3 and a fixed air balancing plate 4. Several fixed air balancing plates 4 are vertically welded to the inner bottom of the cooling tower box 1. At the same time, two adjacent movable air balancing plates 2 are distributed on both sides of a fixed air balancing plate 4. The tops of the movable air balancing plates 2 pass through the through slots provided on the cooling tower box 1 and are welded to the external brackets. A handle 14 is welded on the top of the bracket. The movable air balancing plates 2 are used to be fixedly connected to the fixed air balancing plates 4 by screws. There is a wire brush 3, the bristle end of the wire brush 3 is arranged in contact with the fixed air equalizing plate 4, and the movable air equalizing plate 2 and the fixed air equalizing plate 4 are both provided with a plurality of ventilation holes 27. When the air intake window is blown, the external air can be evenly distributed through the ventilation holes 27 on the movable air equalizing plate 2 and the fixed air equalizing plate 4, and the dirt in the air can be blocked by the densely distributed wire brush to achieve a certain filtering effect. At the same time, the movable air equalizing plate 2, the fixed air equalizing plate 4 and the wire brush 3 are made of stainless steel to store cold energy, relatively reduce the fluctuation of the intake temperature, and effectively ensure the heat dissipation efficiency.

[0037] A nozzle 22 is correspondingly arranged at the top of the air filter structure, and the nozzle is located in a placement groove opened on the top of the box wall on both sides of the front and rear sides of the cooling tower box body 1. At the same time, the nozzle is connected to the threaded hole opened on the surface of the external C-shaped pipe 24. At the same time, one end of the C-shaped pipe 24 is closed and the other end is connected to the water inlet pipe through a manual three-way valve 23. After the entire equipment has been used for a period of time, the three-way valve 23 can be manually adjusted to allow water to be sprayed onto the movable air balancing plate 2, the fixed air balancing plate 4 and the wire brush 3 to achieve flushing. At the same time, during the cleaning process, the movable air balancing plate 2 can be pulled back and forth manually or by equipment to achieve preliminary cleaning of the interior, and finally the movable air balancing plate 2 can be pulled out for separate cleaning.

[0038] An ash collecting trough 5 is placed at the bottom between the fixed air balancing plates 4 to collect the washed sewage, and the ash collecting trough 5 can be drawn out from a notch opened on the side of the cooling tower body 1 .

[0039] As a further solution, the manual three-way valve 23 can also be replaced with a proportional valve. By adjusting the water supply ratio, a portion of water is continuously sprayed on the movable air balancing plate 2, the fixed air balancing plate 4 and the wire brush 3 (the spray amount can be controlled within a very small range). The evaporation of water carries a portion of the heat and carries the low-temperature water vapor to participate in the cooling activity in the anechoic chamber 12. The effect of carrying water vapor is to increase the heat that can be absorbed by the unit volume of air supply, thereby improving the heat exchange efficiency.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
