Description

A detachable cross-flow cooling tower

technical field

The utility model relates to the field of heat exchange equipment, in particular to a detachable cross-flow cooling tower.

Background technique

The cross-flow cooling tower is a cooling tower in which water falls vertically from the upper part of the tower, air flows horizontally through the water spray filler, and the air flow is perpendicular to the water flow. The water exchanges heat and mass with the air flowing through it, resulting in a drop in water temperature. . The cross-flow cooling tower adopts the structure of air intake from both sides and exhaust air from the top. The air is heat-exchanged with hot water through the fillers on both sides, and the hot and humid air is discharged to the outside of the tower. It is mainly used for ground sites with good ventilation conditions and no obstacles.

The Chinese patent with application publication number CN103759548A discloses a cross-flow cooling tower, which includes a cooling tower body, air inlets are arranged on the left and right ends of the cooling tower body, and two packing devices are arranged at the left and right air inlets, and the two packing devices are located in the cooling tower. Inside the main body; two water distribution tanks are installed on the upper side of the two packing devices. The water distribution tanks are located on the upper end surface of the cooling tower body and corresponding to the filling device; The fan can drive the air circulation in the cooling tower body; a central cylinder is installed on the lower surface of the cooling tower body, and the central cylinder is connected with the water outlet; the air cylinder and the central cylinder are located between the two packing devices. The cooling tower can optimize the ventilation system, reduce resistance and save energy, have high operating efficiency, and be more energy-saving and environmentally friendly.

Because some scenic spots and historical sites also need to use cooling towers, but when the above-mentioned cross-flow cooling tower is installed in the scenic spots and historic sites, due to the industrial appearance of the cross-flow cooling tower itself, the cross-flow cooling tower installed in the scenic spots and historical sites will appear very abrupt, affecting The overall aesthetic effect of the scenic spot area; therefore, some will directly put a shell that is suitable for the scenic spot area directly on the shell, but the cooling tower is not stable when it is directly put on; and some will weld a shape-adapted shell for stability. The shell goes up, but it will be very troublesome when soldering.

Utility model content

The purpose of the utility model is to provide a detachable cross-flow cooling tower, which has the advantages of convenient replacement of the shell of the cross-flow cooling tower and stable installation.

The above-mentioned purpose of the utility model is achieved through the following technical solutions:

A detachable cross-flow cooling tower, comprising a cooling tower body, a frame for fixing the cooling tower body, an air inlet arranged on the side wall of the cooling tower body and a casing arranged on the periphery of the cooling tower, the casing is located at the inlet There is a slot at the tuyere to expose the air inlet. The housings are all in the shape of a cube. The inside of the housing is hollow and the upper and lower ends are opened. On the housing, the cooling tower body is provided with a flange near the ground end, and slide rails are arranged on both sides of the air inlet on the flange, and the slide rails are parallel to the bottom edge of the cooling tower body.
