technical field

The utility model relates to a heat exchanging device, in particular to a heat exchanging device which rationally utilizes the heat released by process water in the production process of solar cells to realize the heating of raw water for making pure water, so that the heat energy can be recycled .

Background technique

my country attaches great importance to the research and development of solar cells. As early as the Seventh Five-Year Plan period, the research work on amorphous silicon semiconductors has been listed as a major national topic; etc. In October 2003, the National Development and Reform Commission and the Ministry of Science and Technology formulated a solar resource development plan for the next five years. The Development and Reform Commission's "Bright Project" will raise 10 billion yuan to promote the application of solar power generation technology. It is planned that by 2015, the total installed capacity of the national solar power generation system will be up to 300 MW. my country has become the world's largest manufacturer of photovoltaic products. my country's upcoming "New Energy Revitalization Plan" plans for the installed capacity of photovoltaic power generation in my country to reach 20GW in 2020, which is more than 10% of the 1.8GW in the original "Renewable Energy Medium and Long-Term Plan". times.

The application of solar cells has entered the industry, commerce, agriculture, communications, household appliances and public facilities from the military field and the aerospace field, especially in remote areas, mountains, deserts, islands and rural areas to save the cost. of transmission lines.

We know that in the production process of solar cells, it is necessary to use cold process water to cool down the production equipment. The heated process water is usually transported to the cooling tower built outdoors for cooling and cooling, and the process water is cooled and then returned When it is used in the circulation system, the above-mentioned process water circulation system has many shortcomings and deficiencies, which are specifically manifested in, ①. In the cold winter in the north of our country, the cooling tower for cooling and cooling often freezes. The ice process consumes a lot of electricity and coal. ②. When the heated process water is cooled, the heat is wasted in vain, which is not conducive to the rational utilization of energy.

In addition, pure water needs to be used in the production of solar cells, and the raw water for making pure water needs to be heated to between 18 and 20°C. In the past, electric heating or coal-fired heating was used to heat the raw water, which also caused a lot of energy. waste, but also increased the cost of the production process. How to realize the heating of the raw water through heat exchange with the heat wasted when the process water is cooled, so that the raw water temperature reaches the production requirement between 18-20°C is the problem solved by the utility model.

Contents of the invention

The purpose of this utility model is to provide a simple and reasonable structure, which can reasonably utilize the heat energy generated in the production, and realize the cooling of the process water and the heating of the raw water for making pure water by means of heat exchange, so as to reduce the electric energy and Coal-burning resources waste solar cell production winter process water heat exchange device.

The purpose of this utility model is achieved in that the heat exchange device includes a raw water tank, a circulation pump, a heat exchanger, a water filter tank and a process pump, and a pipeline on the raw water tank is connected to the heat exchange unit through a circulation pump One end of the heat exchanger, the other pipe is connected to the other end of the heat exchanger; one pipe on the water filter tank is connected to one end of the heat exchanger through a process pump, and the other pipe is connected to the heat exchanger the other end of the device.

The utility model has the following advantages owing to adopting said structure:

1. The utility model solves the problem that the cooling tower is easy to freeze in winter when the amount of process water is small.

2. The utility model saves the consumption (consumption of about 10t/day) of using the tap water of the cooling tower.

3. The utility model converts the heat of the process water to the raw water for pure water production through heat exchange, so that the temperature of the pure water reaches the production requirement between 18 and 20°C, thus saving a lot of coal-burning expenses.

Detailed ways

As shown in Figure 1: the heat exchange device includes a raw water tank 1, a circulation pump 2, a heat exchanger 3, a water filter tank 4 and a process pump 5, and a pipeline 6 on the raw water tank 1 passes through the circulation pump 2 Connected to one end of the heat exchanger 3, another pipeline 7 is connected to the other end of the heat exchanger 3; a pipeline 8 on the water filter tank 4 is connected to the heat exchanger 3 through the process pump 5 At one end, another pipeline 9 is connected to the other end of the heat exchanger 3 .

The raw water tank 1 is connected to the device for producing pure water, and the water filter tank 4 is connected to the process water system used in the production.

The working process is as follows: the tap water (raw water) in the raw water tank 1 is sent to a heat exchange channel of the heat exchanger 3 through the circulating pump 2 to form the circulation of the medium I; It is sent to another heat exchange channel of heat exchanger 3 to form the circulation of medium II; the two water media I and II in the heat exchanger exchange heat energy to achieve the temperature rise of the raw water (the temperature rises to between 18 and 20°C ), to cool the process water (the temperature drops to between 18 and 20 ℃), to meet the production requirements.
