Description

Technical Field

[0001] The present invention relates to the field of water treatment, and particularly to reverse osmosis membrane water treatment equipment. Background Art

[0002] On the one hand, water treatment equipment in cold regions is prone to low-temperature damage such as pipeline freezing and condensate icing invading the equipment. On the other hand, as a pressurized equipment, water treatment equipment is prone to accidents in the case of embrittlement caused by low temperature. Therefore, it is required that the temperature in the water treatment equipment room is generally higher than 5°C.

[0003] At the same time, for the reverse osmosis membrane with semi-permeability, under the action of a pressure higher than the osmotic pressure of the solution, only water can pass through the reverse osmosis membrane, while impurities, salts, heavy metal ions, etc. in the water are intercepted, so as to achieve the purpose of separating and purifying water. This requires that during the operation of the reverse osmosis membrane, pressure needs to be provided for water to pass through the reverse osmosis membrane so that water can overcome the osmotic pressure for reverse osmosis. However, when the water temperature is low, the viscosity of water will increase, and the flux of the reverse osmosis membrane will decrease. During the process of the water to be treated changing from low temperature to normal temperature, for every 3% increase in water temperature, the water production increases by 10%. In the case of 20 - 25°C, the water treatment efficiency of the reverse osmosis membrane is the best.

[0004] Therefore, in the water treatment equipment with reverse osmosis membrane equipment, different heating treatments need to be carried out in outdoor low-temperature situations, that is, the ambient temperature of general equipment is given above 5°C, and the water coming into the reverse osmosis membrane is heated to 20°C. Thus, the best winter maintenance of water treatment and the highest water production efficiency of the reverse osmosis membrane are taken into account.

[0005] The prior art usually adopts the form of electric heating tapes, which are wound around the water treatment equipment, only providing the equipment with a minimum heating, which is neither energy-saving nor capable of differential temperature control.

[0006] Higher humidity is also a major threat to water treatment equipment. The humidity of 40 - 60% is the most beneficial to the equipment, but in winter, in order to achieve heat preservation in the water treatment equipment room, the equipment room is highly enclosed to avoid heat exchange. Coupled with the operation of water-related equipment, the humidity in the equipment room is extremely high, and the service life of the equipment is shortened. Summary of the Invention

[0011] The operation method of the temperature and humidity regulation system in the low-temperature zone reverse osmosis membrane water treatment equipment room is as follows: Parameter setting: The real-time temperature measured by the temperature sensor on the end pipe of the solar collector is T1; The real-time temperature measured by the temperature sensor of the heat storage tank is T2; The real-time temperature measured by the temperature sensor of the intermediate water tank is T3; The real-time temperature measured by the temperature sensor mounted on the wall of the equipment room main body is T4; The real-time temperature measured by the humidity sensor mounted on the wall of the equipment room main body is M1; 1) The heating step of the medium in the heat storage tank: A. When T1 - T2 ≥ 20°C, the booster pump on the second liquid inlet pipe starts, the electric valve on the second communication pipe closes, and the medium circulates from the heat storage tank through the second liquid inlet pipe, solar collector, and second liquid outlet pipe, and finally returns to the heat storage tank to form circulating heating; B. When T1 - T2 < 20°C, the circulating heating needs to be stopped, and the booster pump on the second liquid inlet pipe closes; C. To prevent freezing damage, the medium returns, that is, the electric valve on the second communication pipe opens, the medium in the second liquid outlet pipe returns to the heat storage tank by gravity, and the medium in the solar collector returns to the heat storage tank by gravity through the second liquid inlet pipe and the second communication pipe; 2) The room temperature regulation step of the equipment room main body: A. Considering that the air in the equipment room will flow upward during the heating process and heat loss will be caused by the cold bridge formed by the contact part between the equipment room and the outside, the flow blocking layer is stretched to block the air flow between the above-ground part and the underground part of the equipment room main body, and the air in the above-ground part of the equipment room is in a relatively static state, greatly reducing heat loss; B. When T4 ≤ 5°C and T2 ≥ 30°C, the medium in the heat storage tank heats up the equipment room through heat exchange; the electric valves on the first connecting pipe, the electric valve at the front end of the electric heating pipeline, and the electric valve at the rear section of the first liquid outlet pipe are closed, and the two electric valves in the front middle section of the first liquid outlet pipe, the electric valve on the first liquid inlet pipe, and the electric valve on the radiator water inlet pipeline are opened. The booster pump on the first liquid outlet pipe is started, and the medium flows back to the heat storage tank through the heat storage tank, the front middle section of the first liquid outlet pipe, the radiator, and the rear section of the first liquid inlet pipe, and dissipates heat through the radiator until T4 ≥ 10°C, and the booster pump (c) on the first liquid outlet pipe is closed; C. When T4 ≤ 5°C and T2 < 30°C, the temperature difference between the medium and the equipment room is small, and the heat exchange efficiency is low. The temperature is adjusted by electric auxiliary heating; the electric valves on the first connecting pipe, the electric valve at the front end of the electric heating pipeline, and the electric valve on the radiator water inlet pipeline are opened, and the three electric valves in the front, middle, and rear sections of the first liquid outlet pipe and the electric valve on the first liquid inlet pipe are closed. The heating rod in the electric heating pipeline is powered on, and the booster pump on the first liquid outlet pipe is started. The medium forms a closed loop through the first connecting pipe, the electric heating pipeline, the radiator, and a part of the first liquid inlet pipe, and the medium is heated by the heating rod in the electric heating pipeline and dissipates heat through the radiator until T4 ≥ 10°C. The booster pump on the first liquid outlet pipe is closed, and the heating rod in the electric heating pipeline is powered off; 3) Steps for storing and heating water in the intermediate water tank: Before storing and heating water in the intermediate water tank, T4 needs to be heated up to 10°C, and the method is the same as the steps for adjusting the room temperature of the main body of the equipment room, and then the water in the intermediate water tank is heated; A. When T2 ≥ 40°C, the temperature difference between the medium in the heat storage tank and the water to be heated is large, and the heat exchange efficiency is high. Therefore, the medium in the heat storage tank heats up the water stored in the intermediate water tank; the three electric valves on the first liquid outlet pipe and the electric valve on the first liquid inlet pipe are opened, and the electric valve on the first connecting pipe, the electric valve at the front end of the electric heating pipeline, and the electric valve on the radiator water inlet pipeline are closed. The booster pump on the first liquid outlet pipe is started, and thus a closed circulation pipeline for the medium to pass through the heat storage tank, the first water outlet pipe, the temperature increasing kettle, and the first water inlet pipe is formed to heat up the water stored in the intermediate water tank until T3 ≥ 20°C, and the booster pump on the first liquid outlet pipe is closed; B. When T2 < 40°C, the temperature difference between the medium in the heat storage tank and the temperature of the water to be heated is small, and the heat exchange efficiency is low. Therefore, the electric heating rod in the electric heating pipeline heats the flowing medium to heat the water stored in the intermediate water tank; the two electric valves in the front and middle sections of the first liquid outlet pipe, the electric valve on the first liquid inlet pipe, and the electric valve on the radiator water inlet pipeline are closed, the electric valve in the rear section of the first liquid outlet pipe and the electric valve on the first communication pipe are opened, the heating rod in the electric heating pipeline is powered on, and the booster pump on the first liquid outlet pipe is started. Thus, a closed circulation pipeline of the medium passing through the first communication pipe, the electric heating pipeline, the rear section of the first water outlet pipe, the temperature increasing kettle, and the first water inlet pipe is formed to heat the water stored in the intermediate water tank until T3 ≥ 20°C, then the booster pump on the first liquid outlet pipe is closed, and the heating rod in the electric heating pipeline is powered off; 4) The dehumidification step in the main body of the equipment room: Before dehumidifying the main body of the equipment room, T4 needs to be heated to 10°C, and the method is the same as the room temperature adjustment step of the main body of the equipment room; When the humidity M1 ≥ 60%, the blocking layer retracts, enabling the air flow between the above-ground part and the underground part of the main body of the equipment room. The first opening fan and the second opening fan are opened for 10 - 30 seconds. The cold outside air entering through the lower first opening fan sinks to the lower part of the main body of the equipment room due to its low density, and the indoor hot and humid air floats upward due to its high density and is discharged through the upper second opening fan. Then the first opening fan and the second opening fan are closed, and the blocking layer expands and fully covers the upper part of the main body of the equipment room.

[0012] The advantages and positive effects of the present invention are as follows: The reverse osmosis membrane water treatment equipment room in cold regions adopts a semi-underground form, with cavities around the periphery and a blocking layer on the top, minimizing cold bridges to achieve heat preservation; when the solar radiation intensity is high in winter, solar energy is used for heat storage, and the equipment room or the water to be treated can be heated without energy consumption at night; opening fans at different heights are set, and based on the principle that cold air sinks and warm and humid air floats, dehumidification is achieved quickly, realizing rapid dehumidification in a heat-preserved enclosed space; separate circulating heating circuits are adopted for the equipment placement space and the reverse osmosis membrane water to be treated, achieving precise temperature adjustment, saving energy, and significantly increasing the water production of the reverse osmosis membrane in cold regions in winter.

The method is the same as the room temperature adjustment steps of the main body 11 of the equipment room; When the humidity M1 ≥ 60%, the flow-blocking layer 37 retracts, enabling air to flow between the above-ground and underground parts of the equipment room main body 11. The first opening fan 35 and the second opening fan 36 open for 10 - 30 seconds. The cold outside air entering through the lower first opening fan 35 sinks below the equipment room main body 11 due to its low density, while the hot and humid air inside the room floats upward and is discharged through the upper second opening fan 36. Then, the first opening fan 35 and the second opening fan 36 close, and the flow-blocking layer 37 expands and fully covers the upper part of the equipment room main body 11.
