Description

Technical Field

[0001] This utility model belongs to the field of cooling tower technology and relates to an antifreeze device for circulating water cooling towers. Background Technology

[0002] After a long period of operation, a circulating water cooling tower may leak at the inlet valve when it stops running, especially in winter when the ambient temperature is low and the operating time of the circulating water cooling tower is reduced. If the cooling tower inlet valve is not closed tightly or is forgotten to be closed, the circulating water will freeze in the inlet pipe, causing the inlet pipe to crack. Once the circulating water enters the circulating water cooling tower packing layer from the cracked inlet pipe, it can easily cause the packing layer to freeze and be damaged, affecting the normal operation of the subsequent circulating water system. Utility Model Content

[0003] The purpose of this utility model is to provide an antifreeze device for circulating water cooling towers, which addresses the problems existing in the prior art. This device solves the problem that when the inlet valve on the inlet pipe leaks or is left open, the circulating water freezes in the inlet pipe, affecting the normal operation of the cooling tower or damaging the packing layer after seeping into it.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] A circulating water cooling tower antifreeze device includes a circulating water cooling tower body, with an inlet pipe on the side of the circulating water cooling tower body and a cooling water pool below it; the inlet pipe is L-shaped and has an inlet valve, which is located at the vertical section of the inlet pipe.

[0006] A bypass water pipe is provided on the side of the inlet pipe, and the two are connected. The bypass water pipe is equipped with a bypass water valve. A first protective net and a second protective net are symmetrically provided on both sides of the circulating water cooling tower body.

[0007] The diameter of the inlet pipe is larger than the diameter of the bypass pipe.

[0008] The bypass water pipe is L-shaped and includes a horizontal section and a vertical section. The horizontal section of the bypass water pipe is connected to the vertical section of the inlet water pipe. The vertical section of the bypass water pipe passes through the first protective net and its end faces the cooling water pool.

[0009] Both the inlet valve and the bypass valve are butterfly valves, and the inlet valve diameter is larger than the bypass valve diameter.

[0010] The beneficial effects of this utility model are as follows:

[0011] This invention addresses the issue of leaked circulating water entering the cooling water tank directly through the bypass pipe when the inlet valve on the inlet pipe is not closed tightly or is forgotten to be closed. This prevents the circulating water from freezing in the inlet pipe and affecting the normal operation of the cooling tower, or from seeping into the packing layer and damaging it. This reduces potential damage to the circulating water cooling tower, lowers maintenance costs, and extends its service life. Attached Figure Description

[0016] The technical solution of this utility model will be described below with reference to the accompanying drawings and implementation methods.

[0017] like Figure 1 As shown, a circulating water cooling tower antifreeze device includes a circulating water cooling tower body 1, with an inlet pipe 2 on the side of the circulating water cooling tower body 1 and a cooling water pool 8 below it; the inlet pipe 2 is L-shaped and is equipped with an inlet valve 6; specifically, the inlet valve 6 is located in the vertical section of the inlet pipe 2 and is close to the pipe opening.

[0018] A bypass water pipe 4 is provided on the side of the inlet pipe 2, and the two are connected; specifically, the diameter of the inlet pipe 2 is larger than the diameter of the bypass water pipe 4; the bypass water pipe 4 is L-shaped, including a horizontal section and a vertical section, wherein the horizontal section of the bypass water pipe 4 is connected to the vertical section of the inlet pipe 2, the vertical section of the bypass water pipe 4 passes through the first protective net 3, and the end faces the cooling water pool 8.

[0019] The bypass water pipe 4 is equipped with a bypass water valve 5, and the circulating water cooling tower body 1 is symmetrically equipped with a first protective net 3 and a second protective net 7 on both sides; specifically, the inlet valve 6 and the bypass water valve 5 are both butterfly valves, and the diameter of the inlet valve 6 is larger than the diameter of the bypass water valve 5.

[0020] The usage process of this utility model is as follows:

[0021] When the circulating water cooling tower is running normally, close the bypass water valve 5 and open the inlet valve 6. Water enters the cooling tower through the inlet pipe 2 and directly contacts the air entering through the first protective net 3 and the second protective net 7 in the cooling tower through the packing layer, etc., to carry out heat exchange. The water is cooled by evaporation. The cooled water falls into the cooling water pool 8 and then returns to the required equipment for use and circulation, thereby achieving recycling.

[0022] When the circulating water cooling tower stops running, the bypass water valve 5 is opened. At this time, even if the inlet valve 6 is not closed tightly and leaks water or is forgotten to be closed, the water in the inlet pipe 2 will directly enter the cooling water pool 8 through the bypass water pipe 4, thereby avoiding the circulating water from freezing in the inlet pipe and affecting the normal start-up of the cooling tower or from seeping into the packing layer and damaging the packing layer.
