Description

Technical Field

[0001] This utility model relates to the field of water circulation cooling technology, specifically a stainless steel water tank cooling circulation large-diameter backflow anti-collision device. Background Technology

[0002] Stainless steel cooling circulating water tanks are an important component of the circulating system, and are mostly placed on the ground or in low-lying areas. During operation, they must not only withstand the impact of the large-diameter backflow after cooling from the rooftop or high-altitude cooling tower, but also transport the collected return water to the test equipment for cooling via a circulating pump.

[0003] Currently, when stainless steel cooling circulating water tanks are subjected to the impact of large-diameter backflow after cooling from rooftops or high locations, the tanks typically use a single large-diameter pipe directly connected to the cooling water return pipe at the tank inlet. With this single-pipe connection, the return water, without diversion or pressure reduction, rushes directly into the tank through the large-diameter pipe, creating a significant potential energy difference due to the strong and singular water flow impact. Without any backflow impact prevention measures, the tank is prone to leakage or even disintegration within a short period, greatly increasing the risk of water system failure. Furthermore, the operation generates resonance noise, affecting the static operation and maintenance of the water system, posing a severe challenge to the cooling circulating water tank.

The right branch pipe outside the tank is vertically connected to the right branch pipe inside the stainless steel cooling water tank. The bottom of the right branch pipe inside the tank is connected to an elbow.

[0016] Please see Figure 1-2 This utility model provides a technical solution: a large-diameter backflow anti-collision device for cooling circulation in a stainless steel water tank, comprising a main pipe 1, an external left branch pipe 3, an external right branch pipe 4, an internal left branch pipe 6, an internal right branch pipe 7, a slotted straight pipe 11, and a stainless steel cooling water tank 12. Left and right branch pipe supports 5 are installed on the top of the outer wall of the stainless steel cooling water tank 12. External left branch pipes 3 and external right branch pipes 4 are installed horizontally on both sides of the left and right branch pipe supports 5, respectively. The main pipe 1 connects the external left branch pipes 3 and external right branch pipes 4. One end of the main pipe 1 is connected to the return pipe after cooling by the rooftop cooling tower. One end of the left branch pipe 3 outside the box is vertically connected to the left branch pipe 6 inside the stainless steel cooling water tank 12. One end of the left branch pipe 6 inside the box is connected to the elbow 9 inside the box. One end of the right branch pipe 4 outside the box is vertically connected to the right branch pipe 7 inside the stainless steel cooling water tank 12. The bottom end of the right branch pipe 7 inside the box is connected to the elbow 10 inside the box. A slotted straight pipe 11 is connected between the elbow 10 inside the box and the elbow 9 inside the box.

[0017] Furthermore, the main pipe 1 is fixedly connected to the fixed surface through the main pipe support 2, the right branch pipe 4 and the left branch pipe 3 outside the box are fixedly connected to the fixed surface through the left and right branch pipe supports 5, and the left branch pipe 6 and the right branch pipe 7 inside the box are fixedly connected to the internal frame box of the stainless steel cooling water tank 12 through the internal support 8.

[0018] Furthermore, the combined cross-sectional area and flow rate of the left branch pipe 3 and the right branch pipe 4 outside the box are greater than the cross-sectional area and flow rate of the single main pipe 1.

[0019] Furthermore, a square water outlet with its opening facing upwards is provided at equal intervals on the surface of the slotted straight pipe 11. The opening of the water outlet is perpendicular to the water body deep within the stainless steel cooling water tank 12. The water flow rate of the water outlet must be greater than the water flow rate collected between the left branch pipe 6 and the right branch pipe 7 inside the tank.

[0020] Specifically, such as Figure 2 The diagram shown is a schematic of the diversion and pressure reduction structure of the main pipe 1 into the stainless steel cooling water tank 12 of this utility model. The main pipe 1 is a single large-diameter pipe, which is the return pipe after cooling by the rooftop cooling tower. It has a large diameter, high pressure, fast flow rate, and heavy self-weight.

[0021] Step 1: Install the main pipe support 2, the left branch pipe 3 outside the box, the right branch pipe 4 outside the box, and the supports for the left and right branch pipes 5.

[0022] (1) Reinforce the main pipe 1 with the main pipe support 2 to provide fixed support for the main pipe 1. The main pipe support 2 can be composed of an angle iron, two tie wires and fixed expansion bolts, etc.

[0023] (2) An anti-surge measure of first diverting the flow and then reducing the pressure is adopted. Two branch pipes, left and right, are diverted from the main pipe 1 to the outside of the tank: left branch pipe 3 and right branch pipe 4. The single large-diameter main pipe 1 is connected to the stainless steel cooling water tank 12 by welding a double-pass pipe. The left branch pipe 3 outside the stainless steel cooling water tank 12 is a left branch pipe diverted from the main pipe 1, and the right branch pipe 4 outside the tank is a right branch pipe diverted from the main pipe 1, which serves to divert the flow of the single large-diameter water. Note that the cumulative cross-sectional area and diverted water volume of the left branch pipe 3 and the right branch pipe 4 outside the tank should be greater than the cross-sectional area and water flow of the single main pipe 1 in order to divert the water flow of the main pipe 1.

[0024] (3) Reinforce the left and right branch pipe supports 5 on the left branch pipe 3 and the right branch pipe 4 outside the box to provide fixed support for the two branch pipes. The left and right branch pipe supports 5 can be composed of an angle iron, two tie wires and fixed expansion bolts, etc.

[0025] Step 2: Install the left branch pipe 6, the right branch pipe 7, the bracket 8, the elbow 9 of the left branch pipe, and the elbow 10 of the right branch pipe inside the box.

[0026] (1) One end of the left branch pipe 6 inside the tank is positioned above the constant water level in the stainless steel cooling water tank 12 and connected to the left branch pipe 3 outside the tank. The other end is positioned below the constant water level and connected to the elbow 9 of the left branch pipe inside the tank, serving as a connecting link. One end of the right branch pipe 7 inside the tank is positioned above the constant water level in the stainless steel cooling water tank 12 and connected to the right branch pipe 4 outside the tank. The other end is positioned below the constant water level and connected to the elbow 10 of the right branch pipe inside the tank, serving as a connecting link.

[0027] (2) Position the bracket 8 inside the box below the constant water level inside the stainless steel cooling water tank 12 to ensure that there is a certain constant water level inside the stainless steel cooling water tank 12 to supply the circulation pump. Fix the left branch pipe 6 and the right branch pipe 7 inside the box to the channel steel frame structure inside the stainless steel cooling water tank 12 to resolve the impact kinetic energy generated by the water flow and water pressure inside the pipe.

[0028] (3) Position the left branch pipe elbow 9 below the constant water level in the stainless steel cooling water tank 12. Connect one end to the left branch pipe 6 inside the tank and the other end to the slotted straight pipe 11. The left branch pipe elbow 9 is a key component for changing the flow direction of the left branch pipe 6 inside the tank. Position the right branch pipe elbow 10 below the constant water level in the stainless steel cooling water tank 12. Connect one end to the right branch pipe 7 inside the tank and the other end to the slotted straight pipe 11. The right branch pipe elbow 10 is a key component for changing the flow direction of the right branch pipe 7 inside the tank.

[0029] Step 3: Install the slotted straight pipe 11.

[0030] (1) Position the slotted straight pipe 11 in the middle position below the constant water level, and connect it to the left branch pipe 6 and the right branch pipe 7 inside the box.

[0031] (2) A square water outlet with the opening facing upward is provided at the 11th division of the straight pipe. The opening of the outlet is perpendicular to the water body in the depth of the box. Note that the calculated water output of the outlet must be greater than the water flow of the left branch pipe 6 and the right branch pipe 7 in the box that collide with each other. It can receive and resolve the water flow and pressure in the left branch pipe 6 and the right branch pipe 7 in the box.

[0032] When the cooling tower is in operation, one end of the slotted straight pipe 11 receives the water flow and pressure from the left branch pipe 6 inside the tank, and the other end receives the water flow and pressure from the right branch pipe 7 inside the tank. Then, the two water flows with the same speed and opposite direction collide, dissolve and release below the constant water surface, and flow out from the slot of the straight pipe and merge into the water body of the stainless steel cooling water tank 12. The potential kinetic energy of the water flow drop is effectively converted into static kinetic energy below the constant water surface. This can effectively avoid the risk of drop impact and resonance disintegration of the stainless steel cooling water tank 12 caused by the previous single large-diameter backflow. At the same time, it can also effectively eliminate the resonance noise generated by the water flow impact when the cooling tower is working.
