Description

A photothermal photovoltaic combined disinfection device

technical field

The invention relates to a solar disinfection system, in particular to a photothermal photovoltaic combined disinfection device.

Background technique

The high-temperature and high-pressure disinfection device generates high-pressure steam to kill bacteria, fungi and other microorganisms. It is the most reliable and widely used physical sterilization method at present. Among them, the high temperature of the steam can denature or coagulate the proteins of microorganisms (such as various enzymes), resulting in changes in the structure of the proteins and eventually losing their physiological functions. As a result, the metabolism of microorganisms cannot be carried out normally and are killed, so as to achieve the purpose of disinfection. In addition, because the boiling point of water increases with the increase of air pressure, it can generate extremely hot steam with a temperature higher than 100 degrees Celsius under high pressure, thereby increasing the bactericidal effect. In addition, high pressure can also increase the penetration of steam to microorganisms, causing the rupture of microbial cell membranes, causing the outflow of biochemical components in the body and eventually causing cell damage.

When natural disasters occur, they are often accompanied by long-term and large-scale power interruptions. In the face of numerous rescue and disaster relief tasks, how to carry out effective disinfection and sterilization operations in the case of power outages has become a difficult problem for disaster relief personnel. Solar energy, as a ubiquitous energy source that can be converted into both heat and electricity, undoubtedly provides a reliable option to solve this problem.

Contents of the invention

In order to overcome the problems existing in the above-mentioned prior art, the object of the present invention is to provide a combined photothermal and photovoltaic disinfection device, so that in the absence or even interruption of power supply, it can effectively convert solar energy into other forms of energy and finally achieve The effect of sterilization and disinfection.

In order to achieve the above object, the present invention adopts following technical scheme:

A photothermal photovoltaic combined disinfection device, comprising a disinfection system 3, a photothermal system 1 and a photovoltaic system 2 connected to the disinfection system 3; the photothermal system 1 includes a water storage tank 1a connected through a water pipeline 1c and the vacuum heat collection tube group 1b; the photovoltaic system 2 includes a solar cell assembly 2a and a storage battery assembly 2c connected through the first electric wire 2b; the disinfection system 3 includes a high-pressure pump 3a and a sterilization chamber 3b connected, The sterilization chamber 3b is provided with an electric heating device 3c; the vacuum heat collection tube group 1b of the photothermal system 1 communicates with the sterilization chamber 3b of the disinfection system 3 through the hot water pipeline 4; the solar cell of the photovoltaic system 2 Component 2a and battery component 2c are all connected with the high-pressure pump 3a of disinfection system 3 and the electric heating device 3c in the sterilization chamber 3b through the second electric lead 5; The heated high-temperature water is provided to the disinfection system 3; on the other hand, the photovoltaic system 2 is used to convert solar energy into electrical energy, and the generated electrical energy is provided to the high-pressure pump 3a and the electric heating device 3c of the disinfection system 3.

The top cover 3g of the sterilization chamber 3b is provided with an exhaust safety valve 3e, the bottom is connected with a waste liquid discharge pipe 3d, and the sterilization chamber 3b is also provided with a pressure gauge 3f.

The pipe wall of the hot water pipeline 4 should adopt thermal insulation material.

The water storage tank 1a adopts stainless steel or plastic water storage tank.

The solar cell module 2a adopts crystalline silicon solar cells or thin film solar cells.

The storage battery assembly 2c is a lead-acid storage battery, a nickel metal hydride storage battery or a lithium-ion battery.

Compared with the prior art, the present invention has the following advantages:

1. Combining the two utilization modes of solar thermal and photovoltaic, realizes the two-way utilization of solar thermal utilization and solar electricity utilization. On the one hand, the photothermal system is used to convert solar energy into heat energy, and the heated high-temperature water is provided to the disinfection system. On the other hand, photovoltaic systems are used to convert solar energy into electrical energy. The generated electric energy continues to heat the high-temperature water in the disinfection system to generate high-temperature steam, and at the same time supplies the high-pressure pump to generate high pressure. Since the boiling point of water increases with the increase of pressure, higher temperature steam can be generated under high pressure, thereby enhancing the sterilization effect.

2. The water entering the sterilization chamber is pre-heated by the photothermal system, which reduces or even eliminates the need for electric heating devices in the chamber in some cases. As a result, the load on the solar cell components and storage batteries of the photovoltaic system is greatly relieved, thereby reducing the scale of the photovoltaic system.

3. The electric energy generated by the solar cell components can be stored in the battery pack when the system is idle. The storage battery pack can supply power for the disinfection system together with the solar cell components when the system is working, so as to achieve the purpose of stable power supply.

4. Another feature of the present invention is that even when the photothermal system fails to work, unheated cold water can be directly introduced into the sterilization chamber from the water storage tank. The electric heating device in the chamber is powered by a photovoltaic system to generate high temperature water. However, the efficiency of the electric heating of the photovoltaic system will be far inferior to the direct thermal heating of the photothermal system. This is because the photothermal system can directly convert light energy into heat energy, while the photovoltaic system must adopt the conversion process of light-electricity-heat. This indirect conversion process can greatly reduce efficiency and increase losses. Even without considering the loss of the photovoltaic system from electrical energy to thermal energy conversion, the light-to-heat conversion efficiency of the photothermal system is generally better than the light-to-electricity conversion efficiency of the photovoltaic system. Photothermal technology (such as water heaters using solar collector tubes) has also been widely used to heat water in daily life, and has the advantage of mature technology. In principle, both photothermal and photovoltaic technologies can be used to generate heat and electricity. But at the current level of technology, the former has higher heat production efficiency, and the latter has higher power generation efficiency. The invention effectively combines solar thermal and photovoltaic utilization modes, realizes bidirectional utilization of solar thermal utilization and solar electrical utilization, and thus utilizes solar energy resources more effectively.
