Reverse osmosis device discharges hot water cooling water tank

technical field

The invention relates to the technical field of heat dissipation devices, in particular to a heat dissipation water tank used for discharging hot water during thermal disinfection of a reverse osmosis device.

Background technique

The reverse osmosis water treatment equipment in the hospital needs to discharge a certain amount of hot water during thermal disinfection, and the temperature can reach above 90°C, while the drainage pipes in the hospital are mostly PVC pipes, and their temperature resistance value is 60°C. If the hot water is directly Discharge to drain will cause damage to PVC pipe. For example, changing the drainage pipe to other materials with high temperature resistance can solve the problem, but the transformation of the pipe will bring high costs. Therefore, measures need to be taken to cool the discharged hot water to a certain temperature before discharging.

The structure of the existing cooling device is complicated, which can be known from the technology disclosed in the patent No. 01255509.6, the application date is 2001.9.5, and the name is "integrated water circulation cooling device". The cooling device consists of a cooling water tank, It consists of water pump, heat exchanger and cooling fan. The cooling water tank is close to the end face of the heat source, and its close contact is made of materials with good thermal conductivity. The cooling water tank, water pump, and heat exchanger form a circulating waterway through pipelines. The heat exchanger consists of multiple cooling fins and passes through the cooling fins. The tubes of the holes are formed, and the radiator water tank, the heat exchanger and the radiator fan form a whole through the connectors.

Although the heat dissipation device adopting the above structure has a good heat dissipation effect, its structure is too complicated, the cost is high, and it is not easy to install.

Description of drawings

Fig. 1 is a structural schematic diagram of a cooling water tank for discharging hot water in a reverse osmosis device.

Detailed ways

Fig. 1 is the structure schematic diagram of the cooling water tank used for discharging hot water by the reverse osmosis device of the present invention, in the figure: water inlet pipe 1; water tank 2; water outlet pipe 3; hot water A; cooling water B. The top of the water tank 2 is provided with an air outlet 21, the water inlet pipe 1 is fixedly connected to the upper side of the water tank 2, and the inlet of the water inlet pipe 1 communicates with the hot water discharge pipe of the reverse osmosis device. Outlet pipe 3 is inverted U-shaped, and its upper end is provided with air outlet 31, and the lower end is two openings that extend to opposite sides: one is interface 32, and the other is water outlet 33, and interface 32 is fixedly connected in water tank 2 lower sides.

In the present invention, utilizing the principle of water connection, the outlet pipe 3 is made into an inverted U shape with an opening at its upper end. The purpose of this structure is to make there be no pressure difference between the water tank 2 and the outlet pipe 3. The water level is flush with the highest point of the water outlet pipe 3 all the time. When water enters the water inlet pipe 1, the water at the bottom of the water tank 2 will be pushed out through the water outlet pipe 3 due to the pressure difference.

When using the cooling water tank for the first time, the water tank 2 should be filled with cold water first. According to the principle of connection, the water level in the water tank will always be at the same level as the highest point of the water outlet pipe. This state is the state of full water.

According to the principle of thermal expansion and contraction, the higher the temperature of water, the lower the density, so the same volume of hot water is lighter than cold water. When water inlet pipe 1 has hot water A to enter, because hot water A is lighter than cold water, so hot water A can be in the upper layer of water in water tank 2. According to the connection principle again, since the water level of the water tank 2 is higher than the water level at the highest point of the water outlet pipe 3, the cold water at the bottom of the water tank 2 will be pushed out of the water tank 2 through the water outlet pipe 3.

The volume of the water tank 2 is determined according to the amount of hot water discharged by the reverse osmosis device. Since the reverse osmosis device only discharges hot water when it is thermally sterilized, the discharge volume of each thermal disinfection is determined, and the thermal disinfection is performed every day. Do this at most once. Therefore, when the volume of the water tank 2 is greater than the discharge volume of the hot water A of the reverse osmosis equipment, it can be ensured that the cooled cooling water B discharged from the water outlet pipe 3 is always cooled. The volume of the water tank 2 is preferably 1.3 to 1.5 times the discharge volume of the hot water A of the reverse osmosis equipment.

When one discharge ends, the water in the water tank 2 is still full, and it is allowed to cool down naturally. When hot water A enters the water tank next time, the water in the water tank 2 has been cooled, and the above discharge process can be performed again.
