Description

An energy tower that can meet different flow demands

Technical field:

The utility model relates to an energy tower, in particular to an energy tower which can meet different flow demands.

Background technique:

At present, the existing energy towers have the following problems:

(1) The distributor used in the existing energy tower is in the form of a flat groove, with liquid separation holes evenly distributed on it, and the solution flow can only run at 120% and 80% of the design flow. The outflowing solutions are all the same, and the outflow volume cannot be adjusted. If it is to meet the heat exchange demand of heating the solution in winter, it cannot meet the heat exchange demand of large cooling load and large flow requirements in summer. If it is to meet the large cooling load and large flow requirements in summer The heat exchange demand of heating solution in winter cannot meet the heat exchange demand.

(2) The existing energy tower does not have a dedicated liquid distribution tank. When preparing the brine, observing the brine and liquid level control, it is necessary for staff to enter the tower to operate, which is not only very inconvenient, but also affects the air volume during operation. and heat transfer efficiency.

(3) The existing energy tower does not have a rain and snow discharge device. When used in rainy and snowy days, rain and snow can easily enter the energy tower to dilute the refrigerant solution. Although some energy towers are equipped with rain and snow prevention devices: the air outlet is equipped with a curved wind The upper tower body of the air inlet is provided with a tower body eaves cover, but this structure is not completely protected against rain and snow. When it rains and snows, most of the rain and snow still enters the tower to dilute the refrigerant. As a result, the concentration of the brine solution is unstable and the solid brine is frequently added, which not only increases the operating cost, but also increases the workload of the staff and wastes manpower and material resources.

Utility model content:

The purpose of the utility model is to overcome the deficiencies of the prior art above and provide a uniform flow rate, meet different flow requirements, improve heat exchange efficiency, stable and reliable operation, reduce operating costs, reduce the workload of staff, and save manpower. Energy towers with material resources that can meet different flow demands.

The purpose of this utility model can be achieved through the following measures: an energy tower that can meet different flow requirements, it includes a shell that can enter the wind on both sides, and the two ends of the shell are respectively connected with side rain shields, which is characterized in that There are fillers on both sides of the housing, and the top of the fillers on each side of the housing is connected to the distributor. The bottom plate of the distributor is a concave-convex plate. There is a liquid inlet pipe above the device, and a liquid collection tank is provided under each side of the packing in the shell. The two liquid collection tanks are connected by a connecting pipe. Connect the air cylinder, the air cylinder is connected to the motor frame, the motor frame is connected to the motor, and the motor is connected to the fan through the reducer.

In order to further realize the object of the utility model, the distributor is provided with an anti-scouring groove, and the distributor cover is connected above the distributor at the upper end of the housing.

In order to further realize the purpose of the utility model, the upper end of the filler is connected to the rain and snow shield, and the lower part of the housing is connected to the rainwater pan, and a rainwater discharge port is arranged on the rainwater pan.

In order to further realize the purpose of the utility model, the lower end of the side rain shield is provided with a rainwater deflector.

In order to further realize the purpose of the utility model, one of the liquid collection tanks is connected to the liquid distribution tank.

Compared with the prior art, the utility model can produce the following positive effects:

(1) The bottom plate of the distributor of this utility model adopts a concave-convex structure plate, and the concave and convex surfaces are provided with liquid separation holes, and the height of the liquid separation holes is different. When the flow rate is small, the solution can only fill the concave liquid separation holes, ensuring small The flow rate is evenly distributed. When the flow rate is large, the solution not only fills the concave liquid separation hole, but also fills the convex liquid separation hole to increase the flow area and ensure even distribution when the large flow rate is large. It can not only meet the heat exchange demand of the heating solution in winter, but also meet the occasions where the cooling load is large and the flow rate is large in summer. The cooling load in summer is increased by more than 100% compared with that before the improvement.

(2) The utility model is provided with a liquid distribution box connected with the liquid collection box. Not only is it convenient to prepare the brine, observe the brine, and control the liquid level, but also operate during operation without affecting the air volume and heat exchange efficiency. It provides a good place for the preparation of air volume and heat exchange efficiency. Unaffected by flow, stable.

(3) The utility model is equipped with a rain and snow discharge device, which is composed of a rain and snow shield, a rainwater tray, a rainwater discharge port and a rainwater deflector. When it rains and snows, the rain and snow entering the wind duct of the energy tower flows through the top rain and snow plate into the rainwater tray, and is discharged out of the tower by the rainwater discharge port; the rain and snow that passes through the side rain plate flows out through the rainwater deflector. In this way, the external rain and snow cannot mix with the heat exchange solution from the heat pump system. When the utility model is used in rainy and snowy days, it can prevent rain and snow from entering the energy tower to dilute the solution, thereby causing the problem of unstable concentration of the refrigerant solution and frequent addition of solid refrigerant, reducing the operating cost and the work of the staff amount, saving manpower and material resources.

Embodiment 1: An energy tower that can meet different flow requirements (see Figure 1-Figure 4), which includes a housing 12 that can be ventilated on both sides, and the left and right ends of the housing 12 are respectively connected with side rain shields 8. There are fillers 7 on the left and right sides of the housing 12, and the distributor 5 is connected above the fillers 7 on each side of the housing 12. The bottom plate of the distributor 5 is a concave-convex plate, and its convex surface 5-1 and concave surface 5 -2 are equipped with evenly distributed liquid separation holes. Distributor 5 is provided with anti-scouring groove 6, distributor cover 14 is connected above distributor 5 at the upper end of housing 12, liquid inlet pipe 4 is provided above distributor 5 on housing 12, and filler 7 on each side of housing 12 The lower part of each is provided with a liquid collection box 9, and the two liquid collection boxes 9 are connected by a connecting pipe 10, and one of the liquid collection boxes 9 is provided with a liquid outlet 11.
