Description

Technical Field

[0001] The utility model belongs to the technical field of high-purity water production equipment, and particularly relates to a high-purity water production device. Background Technique

[0002] High-purity water, also known as ultra-pure water or pure water, is water with extremely high chemical purity. Its key characteristic is extremely low conductivity, usually above 0.1 MΩ·cm, indicating that there are almost no ions or other charged particles in high-purity water. The preparation of high-purity water is usually achieved through processes such as distillation, reverse osmosis, ion exchange, ultrafiltration, and UV disinfection to remove impurities in water, including minerals, salts, bacteria, microorganisms, dissolved gases, and other organic substances.

[0003] In the daily experiments of the engineering test and monitoring institute, high-purity water is required. Since high-purity water has extremely high requirements for water quality, its storage and transportation require the use of special pollution-free containers and pipelines to avoid secondary pollution. The requirements for pollution-free containers and pipelines result in high environmental requirements during the transfer of high-purity water, and the probability of being contaminated during the transfer process is extremely high. Since high-purity water production equipment is usually large in volume and fixedly set in one location, people cannot apply it immediately after high-purity water is generated, thus causing great inconvenience. Content of the Utility Model

[0004] Aiming at the above existing problems, the purpose of the utility model is to provide a high-purity water production device that can directly obtain high-purity water for engineering tests.

[0005] The technical solution of the utility model is: a high-purity water production device, comprising:

[0006] A heating tank, internally provided with a heating device, which is used to heat the water introduced into the heating tank to generate water vapor;

[0007] A guiding pipe, one end of which is arranged at the top of the heating tank and is communicated with the inside of the heating tank, and is used to discharge the water vapor out of the heating tank;

[0008] A cooling pipe, one end of which is communicated with the other end of the guiding pipe, and is used to cool the water vapor to generate high-purity water;

[0009] A vacuum tank, arranged outside the heating tank and communicated with the inside of the heating tank;

[0010] An exhaust assembly, connected to the vacuum tank, and is used to evacuate the air inside the vacuum tank to maintain a vacuum state.

[0011] Further, the inside of the vacuum tank always maintains a medium vacuum state.

[0012] Further, the exhaust assembly includes:

[0013] An exhaust pipe, which is connected to a vacuum tank, and a first vacuum valve is provided on the exhaust pipe;

[0014] A vacuum pump, which is connected to the exhaust pipe and is used to extract vacuum from the vacuum tank.

[0015] Further, a first connecting pipe is connected to the heating tank, the first connecting pipe is connected to a second vacuum valve, and the second vacuum valve is connected to the vacuum tank through a second connecting pipe, so as to realize an on-off setting between the vacuum tank and the heating tank.

[0016] Further, the guiding pipe is vertically arranged above the heating tank, and the cooling pipe and the guiding pipe form an inverted U-shaped structure.

[0017] Further, the cooling pipe includes:

[0018] A reduced-diameter pipe, which is in a funnel-shaped structure, and the end with a larger diameter is connected to the guiding pipe;

[0019] A spiral pipe, one end of which is connected to the end with a smaller diameter of the reduced-diameter pipe;

[0020] A water outlet pipe, which is connected to the other end of the spiral pipe;

[0021] An outer pipe, which is sleeved outside the reduced-diameter pipe, the spiral pipe, and the water outlet pipe. One end of the reduced-diameter pipe penetrates through the outer pipe, and the other end of the water outlet pipe penetrates through the outer pipe. The inner wall of the outer pipe and the outer wall of the spiral pipe form a cooling cavity, and a water inlet and a water outlet are provided on the cooling cavity. The cooling cavity is used to fill cold water.

[0022] Even further, the cooling pipe further includes a water inlet pipe and a connecting pipe. One end of the water inlet pipe is connected to an external water source, and the other end of the water inlet pipe is connected to the water inlet. The water inlet pipe is used to introduce cold water into the cooling cavity; the connecting pipe is connected to the water outlet, and the connecting pipe is used to discharge the heat-exchanged cold water out of the cooling cavity.

[0023] Even further, a valve is provided on the water outlet pipe.

[0024] Further, a water inlet pipe connected to the heating tank is connected to the bottom of the heating tank, and a water inlet valve is connected to the water inlet pipe.

[0025] The working method of the present utility model: When in use, only need to introduce water through the water inlet pipe so that the water can enter the heating tank, and then close the water inlet valve and the valve on the water outlet pipe to keep the heating tank in a sealed state. Then open the second vacuum valve to balance the air pressure between the vacuum tank and the heating tank 1, so that the air pressure in the heating tank is reduced.

[0026] Then, close the second vacuum valve again so that the heating tank and the vacuum tank are each independently sealed. To ensure that the vacuum degree in the vacuum tank remains at a medium vacuum degree, open the first vacuum valve and the vacuum pump so that the air in the vacuum tank leaves through the exhaust pipe, thereby increasing the vacuum degree in the vacuum tank and preparing for the next operation. Then, close the first vacuum valve and the vacuum pump.

[0027] Then, the heating device heats the heating tank, causing the water in the heating tank to be heated and turn into water vapor. The water vapor enters the necked pipe through the guiding pipe. Then, the water vapor contacts the necked pipe and the spiral pipe, forming high-purity water after condensation and leaving through the water outlet pipe. The operator only needs to open the valve on the water outlet pipe to extract the high-purity water. The external water source will enter the cooling chamber through the water inlet pipe and discharge through the connecting pipe, enabling the cooling chamber to continuously maintain the temperature condition for condensation, ensuring that the spiral pipe is in a low-temperature environment so that the water vapor can be condensed, facilitating people to obtain high-purity water. In this way, there is no need to use a container to transfer the high-purity water, and the high-purity water can be directly extracted, avoiding contamination during the transfer process. Among them, the heating device uses a commercially available electric heating wire.

[0028] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0029] Based on the heating tank, the present utility model provides a connected vacuum tank. The vacuum tank creates a vacuum environment under high pressure, which can not only maintain the pressure in the heating tank in a stable state close to medium vacuum, but also kill or inhibit microorganisms in the heating tank, playing a sterilization role to ensure a sterile environment inside the heating tank and enabling more convenient provision of high-purity water that meets the requirements.

[0030] During use, water is fed into the heating tank, and the heating tank is kept relatively sealed. Then, the vacuum tank is connected to it, quickly reducing the air pressure in the heating tank. Then, the two are separated again, and the vacuum degree in the vacuum tank is readjusted to prepare for the next operation. The heating tank is ready to heat the water in it to generate water vapor as soon as possible and introduce it into the cooling pipe for cooling, and the distilled water leaves through the water outlet pipe and is supplied to people as high-purity water. This water production device is small in size and convenient to carry, and high-purity water can be directly obtained without using a container or pipeline for transfer, avoiding its contamination.

The exhaust pipe 51 is communicated with the vacuum tank 4, and a first vacuum valve 510 is arranged on the exhaust pipe 51; the vacuum pump 52 is communicated with the exhaust pipe 51 for extracting vacuum from the vacuum tank 4. The vacuum pump 52 can be used to make the inside of the vacuum tank 4 in a vacuum state.

Through the second vacuum valve 11, the connection and disconnection between the heating tank 1 and the vacuum tank 4 can be realized, so that the vacuum state between the two tanks can be flexibly adjusted according to process requirements.

[0042] Preferably, the guiding pipe 2 is vertically arranged above the heating tank 1, and the cooling pipe 3 and the guiding pipe 2 form an inverted U-shaped structure.

Moreover, the water vapor passing through the guiding pipe 2 can be cooled by the cooling pipe 3 and then flow downward naturally under the action of gravity.

[0043] Preferably, as Figure 2 、 Figure 3As shown in the figure, the cooling pipe 3 includes a reduced-diameter pipe 31, a spiral pipe 32, a water outlet pipe 33, and an outer pipe 34.

The inner wall of the outer pipe 34 and the outer wall of the spiral pipe 32 form a cooling cavity 30. The cooling cavity 30 is provided with a water inlet and a water outlet, and the cooling cavity 30 is used to fill cold water.

[0044] Preferably, the cooling pipe 3 further includes a water guiding pipe 35 and a connecting pipe 36.

It should be noted that the water guiding pipe 35 and the connecting pipe 36 are connected by a flexible hose, and there are two water guiding pipes 35 and two connecting pipes 36 respectively. The flexible hoses are not drawn in the attached drawings of this embodiment specification. Figure 3 The flexible hoses are not shown.

[0045] Preferably, the water outlet pipe 33 is provided with a valve. The valve can be used to control the on-off of pure water in the water outlet pipe 33, which is convenient for use. The valve is opened when in use and closed when not in use.

[0046] Preferably, the bottom of the heating tank 1 is connected with a water inlet pipe 13 communicating with it, and a water inlet valve 14 is connected to the water inlet pipe 13. The water inlet valve 14 can be used to control the on-off of the water entering the heating tank 1, and closing the water inlet valve 14 can conveniently create a sealed environment in the heating tank 1.

[0047] The working method of the above embodiment is as follows:

[0048] When in use, only need to introduce water through the water inlet pipe 13 so that the water can enter the heating tank 1. Then close the water inlet valve 14 and the valve on the water outlet pipe 33 to keep the heating tank 1 in a sealed state. Then open the second vacuum valve 11 to balance the air pressure between the vacuum tank 4 and the heating tank 1, so that the air pressure in the heating tank 1 is reduced.

[0049] Then close the second vacuum valve 11 again to make the heating tank 1 and the vacuum tank 4 independently sealed. In order to ensure that the vacuum degree in the vacuum tank 4 remains at a medium vacuum degree, open the first vacuum valve 510 and the vacuum pump 52 so that the air in the vacuum tank 4 leaves through the exhaust pipe 51, thereby increasing the vacuum degree in the vacuum tank 4 and preparing for the next work. Then close the first vacuum valve 510 and the vacuum pump 52.

[0050] Subsequently, the heating device heats the heating tank 1, causing the water in the heating tank 1 to be heated and then form water vapor. The water vapor enters the necked tube 31 through the guiding tube 2. Then, the water vapor contacts the necked tube 31 and the spiral tube 32, thereby forming high-purity water after condensation and leaving through the water outlet pipe 33. The operator only needs to open the valve on the water outlet pipe 33 to extract the high-purity water. External water sources will enter the cooling chamber 30 through the water inlet pipe 35 and be discharged from the connecting pipe 36, enabling the cooling chamber 30 to continuously have the temperature conditions for condensation, thus ensuring that the spiral tube 32 can be in a low-temperature environment for the water vapor to condense, facilitating people to obtain high-purity water. In this way, there is no need for a container to transfer the high-purity water, and the high-purity water can be directly extracted, avoiding the effect of being contaminated during the transfer process.
