Description

Cooling tower air cooling auxiliary equipment

technical field

The utility model relates to a steam condensing device, in particular to a cooling tower air-cooling auxiliary device.

Background technique

In reality, such a situation is often encountered: due to the expansion of production scale or the aging of the original steam condensing equipment, the original steam condensing equipment cannot meet the production needs. At this time, the method of upgrading or updating the original equipment is generally adopted. The above method not only has high cost, but also has a long cycle, high energy consumption and large water consumption.

Contents of the invention

The purpose of this utility model is to provide a cooling tower air-cooling auxiliary equipment to solve the problems of high cost, long cycle, high energy consumption and large water consumption for replacement or transformation of old equipment.

The utility model is mainly composed of a tower body, an induced draft fan, a finned sleeve heat exchange tube bundle, and a filter screen. Inside the tower body, a filter screen is arranged under the heat exchange tube bundle of finned sleeves, the heat exchange tube bundle of finned sleeves is composed of several finned condenser tubes, and water collection tanks are respectively installed at both ends of the heat exchange tube bundle of finned sleeves, wherein A water inlet is set on the outside of one water collection tank, and a water outlet is set on the outside of the other water collection tank. The boxes are respectively provided with feed inlets, and the inner sides of the two ring-gap tube boxes are respectively connected with the ring-gap channels of the fin condenser tubes.

The finned condensation tube is composed of an outer finned tube and one or more inner light tubes, and several support plates are arranged between the outer finned tubes and the inner light tubes.

Each of the above equipment is equipped with 1-4 induced draft fans.

This equipment can be connected in series to the original pipeline when in use, the water inlet of the water collection tank is connected to the water outlet of the original system circulating water, and the water outlet of the water collection tank is connected to the water inlet of the original system circulation water, which has the advantages of short renovation period, Low cost, energy saving and water saving features.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the structural diagram when the utility model is connected with the original equipment.

In the figure: 1 tower body, 2 water inlet, 3 water collection tank, 4 annular gap tube box, 5 feed inlet, 6 outer finned tube, 7 support plate, 8 inner light pipe, 9 annular gap channel, 10 induced draft fan, 11 ring gap tube box, 12 water collection tank, 13 water outlet, 14 feed inlet, 15 filter screen, 16 finned sleeve heat exchange tube bundle.

The specific implementation method Embodiment 1:

As shown in the figure: the induced draft fan 10 is set above the tower body 1, the finned tube heat exchange tube bundle 16 is set inside the tower body 1, the filter screen 15 is set under the finned tube heat exchange tube bundle 16, the finned tube tube bundle The heat exchange tube bundle 16 is composed of several finned condenser tubes, and the two ends of the finned sleeve heat exchange tube bundle 16 are respectively provided with water collection tanks 3 and 12, and the water inlet 2 is provided on the outside of one of the water collection tanks 3, and the water inlet 2 is provided on the outside of the other water collection tank 12. The water outlet 13, the inner side of the two water collecting tanks 3, 12 communicate with the inner light tube 8 of the finned sleeve tube bundle 16, the inner sides of the two water collecting tanks 3, 12 are provided with annular gap tube boxes 4, 11, and the two annular gap tube boxes 4 11 and 11 are respectively provided with feed inlets, and the inner sides of the two annulus tube boxes 4 and 11 communicate with the annulus channel 9 of the fin-tube heat exchange tube bundle 16 respectively.

The fin condenser tube is assembled by an outer finned tube 6 and an inner light tube 8 , and a support plate 7 is arranged between the outer finned tube 6 and the inner light tube 8 . Each device is equipped with 2 induced draft fans.

Embodiment 2: The difference between embodiment 2 and embodiment 1 is that the finned condenser tube is made up of one outer finned tube 6 and four inner light tubes 8 . All the other are identical with embodiment 1.

When in use, the steam enters the annular gap tube box on one side of the fin casing tube bundle through the pipe and the annular gap channel cools down and condenses, then flows into the annular gap tube box on the other side and is discharged through the pipe, and at the same time, the original system circulating water enters the fin casing through the pipe The water collection tank on one side of the tube bundle and the heat exchange in the inner light tubes heat up and flow into the water collection tank on the other side through the pipes to return to the original circulating water system, then cool down and recycle. Under the strong draft of the fan, the cold air from the outside sweeps over the surface of the fins to take away the heat released by the steam in the fin sleeves, and the steam in the annular gap channel is cooled by the inner and outer cooling methods, and the steam is quickly condensed and discharged out of the fins. Sheet casing tube bundle. The non-condensable gas is drawn out by a vacuum pump.
