Description

Energy-saving and environmentally friendly flue gas whitening system device

Technical Field

This utility model relates to the field of fitness equipment, specifically to an energy-saving and environmentally friendly flue gas whitening system device.

Background Technology

Cooling towers are widely used in industrial production to cool circulating water. However, during operation, cooling towers emit a large amount of hot and humid flue gas. This flue gas is prone to forming white water mist, commonly known as "white smoke," in low-temperature environments. White smoke not only affects the visual effect but also causes certain pollution to the environment. Therefore, a flue gas whitening device with a simple structure, low energy consumption, and good effect is needed.

Utility Model Content

In view of the problems existing in the background art, the purpose of this utility model is to provide an energy-saving and environmentally friendly flue gas whitening system device, which effectively solves the problems existing in the background art.

To achieve the above objectives, the present invention adopts the following technical solution:

An energy-saving and environmentally friendly flue gas whitening system includes a flow guide hood installed in the cooling tower air chamber. The flow guide hood has two symmetrically arranged downward-sloping outlets, and a drain pipe is also installed on the flow guide hood. The outlet of the drain pipe extends to the cooling tower water pool. A condensing plate assembly is installed at each of the two outlets of the flow guide hood. The condensing plate assembly includes multiple parallel hollow condensing plates. The front and rear ends of the hollow condensing plates are respectively connected to a first distribution box and a first collection box. A heating plate assembly is also installed at the inlet of the cooling tower air duct. The heating plate assembly includes multiple parallel hollow heating plates. The front and rear ends of the hollow heating plates are respectively connected to a second collection box and a second distribution box. A first connecting pipe is installed between the second distribution box and the first collection box. A circulating pump is installed on the first connecting pipe. A second connecting pipe is installed between the second collection box and the first distribution box. The condensing plate assembly, heating plate assembly, first distribution box, first collection box, second collection box, second distribution box, first connecting pipe, and second connecting pipe are all filled with liquid heat exchange medium.

Furthermore, the cooling tower air chamber is equipped with a filter cotton lining corresponding to the outlet of the flow guide shroud.

Furthermore, the air deflector includes a V-shaped section and an M-shaped cover correspondingly disposed above the V-shaped section.

Furthermore, the adjacent hollow condenser plates are connected by multiple flow pipes.

Furthermore, the adjacent hollow heating plates are also connected by multiple flow pipes.

This utility model has the following beneficial technical effects:

This invention effectively reduces the water vapor content in flue gas and eliminates white mist through the combined use of condensing plate assembly and heating plate assembly. The condensing plate assembly condenses some of the water vapor in the flue gas into water droplets, while the heating plate assembly heats the condensed flue gas, reducing its relative humidity and thus preventing the formation of white smoke. In addition, since both outlets of the guide shroud are angled downwards, the condensed droplets are less likely to be carried back to the cooling tower outlet by the airflow, resulting in better gas-water separation compared to existing equipment. This invention has a simple structure, low energy consumption, low operating costs, and is suitable for various types of cooling towers, with broad application prospects.

As shown in Figures 1 and 2, the energy-saving and environmentally friendly flue gas whitening system device described in this embodiment includes a flow guide hood installed in the cooling tower air chamber. The flow guide hood has two symmetrically arranged downward-sloping outlets 1. Specifically, the flow guide hood includes a V-shaped section 2 and an M-shaped hood 3 correspondingly installed above the V-shaped section 2. The front and rear sides of the flow guide hood are respectively pressed against the front and rear walls of the cooling tower air chamber, so that the air from the cooling tower packing layer enters the V-shaped section 2. A drain pipe 4 is also provided on the flow guide hood. The inlet of the drain pipe 4 is located at the lower part of the outer side of the V-shaped section 2, and the water flow outside the V-shaped section 2 can enter the drain pipe 4. The outlet of the drain pipe 4 extends to the cooling tower water pool. A condensing plate group 5 is respectively installed at the two outlets of the flow guide hood. The condensing plate group 5 includes multiple parallel hollow condensing plates 6. Adjacent hollow condensing plates 6 are connected by multiple flow pipes 7. The front and rear ends of the hollow condensing plates 6 are respectively connected to a first distribution box and a first collection box 8. The first distribution box is located on the front side of the cooling tower, and the first collection box 8 is located on the rear side of the cooling tower.

A heating plate assembly 9 is also installed at the inlet of the cooling tower air duct. The heating plate assembly 9 includes multiple parallel hollow heating plates 10. Adjacent hollow heating plates 10 are also connected by multiple flow pipes 7. The front and rear ends of the hollow heating plates 10 are respectively connected to a second collector box and a second distributor box 11. The second distributor box 11 is located on the rear side of the cooling tower, and the second collector box is located on the front side of the cooling tower. A first connecting pipe 12 is provided between the second distributor box 11 and the first collector box 8. A circulation pump is installed on the first connecting pipe 12. A second connecting pipe is provided between the second collector box and the first distributor box.

The condenser plate assembly 5, the heating plate assembly 9, the first distribution box, the first collection box 8, the second collection box, the second distribution box 11, the first connecting pipe 12, and the second connecting pipe are all filled with liquid heat exchange medium, preferably water.

The cooling tower air chamber is equipped with a filter cotton liner 13 corresponding to the outlet of the guide shroud. Preferably, the filter cotton liner 13 is attached to the left and right side walls inside the cooling tower air chamber. After the liquid droplets carried by the airflow at the outlet of the guide shroud come into contact with the filter cotton liner 13, they can be intercepted by the filter cotton liner 13. After saturation, they drip to the outside of the V-shaped section 2. This can further prevent the airflow from carrying the condensed liquid droplets to the air outlet of the cooling tower, thereby improving the gas-liquid separation efficiency. In addition, since both outlets 1 of the guide shroud are inclined downward, the condensed liquid droplets are not easily carried by the airflow back to the cooling tower outlet. Compared with the existing equipment, the gas-liquid separation effect is better.

The working principle of this embodiment is as follows:

After being humidified and heated within the packing layer, the airflow enters the V-shaped section 2, splits in two at the middle of the V-shaped section 2, and enters the M-shaped hood 3. After being guided by the M-shaped hood 3, the airflow reaches the outlet 1 of the guide hood and exchanges heat with the condenser plate group 5. The airflow temperature decreases, and some water vapor condenses into droplets that accumulate at the lower outer side of the V-shaped section 2 and eventually reaches the cooling tower water pool through the drain pipe 4. After passing through the condenser plate group 5, the airflow turns upward and is heated by the heating plate group 9 before being discharged by the cooling tower duct. In the above process, the condenser plate group 5 effectively reduces the water vapor content in the gas and eliminates white water mist, while the heating plate group 9 heats the condensed flue gas, reduces its relative humidity, and prevents the formation of white smoke.

After absorbing heat and heating up, the liquid heat exchange medium in the condenser plate group 5 reaches the second distribution box 11 through the first collector box 8 and the first connecting pipe 12 on the rear side of the cooling tower, and then enters the heating plate group 9 to heat the air exiting the tower. After releasing heat and cooling down, the liquid heat exchange medium in the heating plate group 9 reaches the first distribution box through the second collector box and the second connecting pipe on the front side of the cooling tower, and then is sent back to the condenser plate group 5, thus completing the cycle.

The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
