Description

[Detailed explanation of the idea] The present invention relates to an improved cooling tower device for areas with heavy snowfall.

When a conventional type of cooling tower is installed in an area with heavy snowfall, the air outlet, outside air intake, and other areas must be cleared of snow, otherwise the capacity will decrease due to snow accumulation and the operation cannot continue.

In addition, even when the vehicle was stopped, snow removal was required if there was a large amount of snow.

The present invention aims to improve this point, and provides a cooling tower system that can be operated continuously without requiring snow removal work, even if it has a relatively large capacity.

That is, the cooling tower device for snow-covered areas of the present invention has a window on one side wall, a window on the opposite side wall, and a sloped roof. This is a cooling tower device that houses a water tank in its entirety.The water tank is installed directly under the sloping roof, and a packing layer is installed below this water tank, and a lower water tank is installed below that, and the blower 4 is installed on the side of the packing layer. It is characterized in that the outside air sucked into the blower is taken in through a window on one side wall, and the exhaust gas that has passed through the packing layer is discharged through the other window.

In the cooling tower system of the present invention, all the equipment necessary to construct the cooling tower is housed inside a building equivalent to a single-family house, and outside air is brought into the building from one window. Since the exhaust air is discharged from the windows of the building, outside air intake and exhaust from the cooling tower equipment are carried out inside the building, preventing contact with snow outside the building, and the water tank is installed on a sloped roof. Because it is installed directly under the roof, the heat held by the water to be cooled before it is used for cooling can warm the roof from within, and this allows snow that has accumulated on the sloped roof to fall automatically. .

By building the building in such a way that no ventilation is allowed except for the windows, and configuring the forced ventilation path inside the building to be unidirectional from one window to the other, even in the summer and mid-season when there is no snowfall, , ventilation can be done as effectively as in a traditional cooling tower.

To further explain with reference to the drawings, the illustrated embodiment shows an example in which two independently operable cooling tower cells are housed inside one building, and both cells are constructed from exactly the same equipment.

As shown in the figure, the device of the present invention uses a window 2 provided on one side wall of a detached house with a sloping roof 1 as an outside air intake, and a window 3 provided on the opposite side wall as an exhaust outlet. Two mechanical ventilation paths are formed by two blowers 4 facing from the window 3, and a filling layer 5 is installed in both ventilation paths, and water to be cooled is sprinkled on each of the filling layers 5. It is.

In the figure, 6 is a water tank, 7 is a rectifying plate, 8 is an eliminator, 9 is a lower water tank, 10 is an electric motor, 11 is a reducer, 12 is an ascending/descending staircase, 13 is an entrance/exit door, and 14 is a snow shutter. There is.

In each cell, water to be cooled is sent to a water sprinkling tank 6 through a water supply pipe 15, and is sprinkled from this water sprinkling tank 6 onto a filling layer 5. After being cooled by coming into contact with a forced air flow in a cross-flow manner, it falls into the lower water tank 9.

The cooled water stored in the lower water tank 9 is supplied to various processes through a water supply pipe 16.

The air flow of this device is such that outside air is taken indoors through the window 2 by the drive of the blower 4, and after coming into contact with water spray at the filling layer 5, it is discharged outdoors through the window 3.

In order to make this flow more effective, it is recommended to form three independent spaces inside the building.

One is the suction side space A' on the side of the window 2 divided by the partition wall 17, and the second is the partition wall 1 at the position where the water tank 6 is located.
The upper space B1 divided by 7 and 18 has a discharge side space C7 extending from the blower 4 to the windows 3 and 3.

The suction side space A is used as a machine room, the upper space B is used as an inspection room, and the suction side space C is used as a heat exchange room.

As a result, ventilation is carried out through the airflow path passing from the suction side space A to the discharge side space C. However, by providing the independent upper space B, the air discharged from the filling layer 5 and the eliminator is returned to the suction side space. The entire amount flows toward the window 3 without being circulated to A, and unidirectional ventilation for heat exchange can be effectively performed.

This also makes it possible to provide a sufficient gap between the blower 4 and the window 2 in the space A, and a sufficient gap between the eliminator 8 and the window 3 in the space C, and these gaps are sufficient to prevent snow damage. do useful work.

That is, these gaps prevent snow from blowing in from the windows 2 and 3 from accumulating and directly accumulating on internal equipment.

Further, snow shutters 14 are attached to the windows 2 and 3, and are lowered to block snow from blowing in when the machinery is stopped or idle.

The roof will have a gabled shape, which is not seen on conventional cooling towers, and will have a slope such as a single roof that will allow snow to slide off naturally.

Since the water sprinkler tank 6 is located directly under the roof, the natural falling of the snow is further assisted by the snow-melting action of the heat retained in the water to be cooled.

□In this way, the device of the present invention can prevent deterioration of equipment functionality due to snow accumulation and snow blowing, and can also avoid snow removal work. Also, this snow damage prevention effect prevents the deterioration of ventilation capacity when there is no snow accumulation. Since it can be realized without any inconvenience, the stated purpose can be achieved effectively □1
