Description

Technical Field

[0001] This utility model relates to the field of water treatment, and in particular to reverse osmosis membrane water treatment equipment. Background Technology

[0002] On the one hand, water treatment equipment in cold regions is prone to low-temperature damage such as pipe freezing and cracking, and condensate freezing and damaging the equipment. On the other hand, as pressurized equipment, water treatment equipment is susceptible to accidents due to embrittlement caused by low temperatures. Therefore, the temperature inside water treatment equipment rooms should generally be above 5°C.

[0003] Meanwhile, reverse osmosis membranes, being semi-permeable, allow only water to pass through under pressure higher than the osmotic pressure of the solution, while impurities, salts, and heavy metal ions are retained, thus achieving water separation and purification. This requires providing pressure to the water during operation, enabling it to overcome osmotic pressure and undergo reverse osmosis. However, at lower water temperatures, the viscosity increases, and the flux of the reverse osmosis membrane decreases. During the process of the water body changing from low temperature to room temperature, for every 3% increase in water temperature, the permeate flow rate increases by 10%. The optimal water treatment efficiency of reverse osmosis membranes is achieved at 20-25℃.

[0004] Therefore, in water treatment equipment equipped with reverse osmosis membranes, different heating treatments are required in low outdoor temperatures. Specifically, the ambient temperature for general equipment is increased to above 5°C, while the incoming water to the reverse osmosis membrane is heated to 20°C. This balances optimal winter maintenance of water treatment with the highest possible reverse osmosis membrane permeability.

[0005] Existing technologies typically use electric temperature tracing tape, which is wrapped around the water treatment equipment to provide only a minimum temperature rise. This is neither energy-efficient nor allows for differentiated temperature control.

[0006] High humidity is also a major threat to water treatment equipment. Humidity of 40-60% is most beneficial to the equipment, but in winter, water treatment equipment rooms are highly enclosed to prevent heat exchange in order to maintain heat. In addition, the operation of water-related equipment leads to high humidity in the equipment room, which shortens the service life of the equipment. Utility Model Content

[0040] The operation method of the temperature and humidity control system in the low-temperature zone reverse osmosis membrane water treatment equipment room is as follows:

[0041] Parameter settings:

[0042] The real-time temperature measured by the temperature sensor at the end pipe of the solar collector is T1;

[0043] The real-time temperature measured by the temperature sensor in the heat storage tank is T2;

[0044] The real-time temperature measured by the temperature sensor in the intermediate water tank is T3;

[0045] The real-time temperature measured by the temperature sensor mounted on the main wall of the equipment room is T4;

[0046] The real-time temperature measured by the humidity sensor mounted on the main wall of the equipment room is M1;

[0047] 1) The heating step of the medium in the heat storage tank:

[0048] A. When T1-T2≥20℃, the booster pump on the second inlet pipe starts, the electric valve on the second connecting pipe closes, and the medium flows from the heat storage tank through the second inlet pipe, the solar collector, the second outlet pipe, and finally back to the heat storage tank to form a circulating heating.

[0049] B. When T1-T2 < 20℃, the circulating heating needs to be stopped and the booster pump on the second inlet pipe needs to be turned off;

[0050] C. To prevent freezing damage, the medium is refluxed, that is, the electric valve on the second connecting pipe is opened, and the medium in the second outlet pipe flows back to the heat storage tank by gravity from the second outlet pipe. The medium in the solar collector flows back to the heat storage tank by gravity through the second inlet pipe and the second connecting pipe.

[0051] 2) Steps for adjusting the room temperature of the main equipment room:

[0052] A. Considering that the air inside the equipment room will flow upward during the heating process and that heat loss will be caused by the cold bridge formed by the part of the equipment room in contact with the outside, the flow barrier layer is stretched to block the air flow between the above-ground part and the underground part of the main body of the equipment room. The air in the above-ground part of the equipment room is in a relatively static state, which greatly reduces heat loss.

[0053] B. When T4≤5℃ and T2≥30℃, the medium in the heat storage tank heats the equipment room through heat exchange; the electric valve on the first connecting pipe, the electric valve at the front end of the electric heating pipe, and the electric valve at the rear end of the first outlet pipe are closed; the two electric valves at the front and middle sections of the first outlet pipe, the electric valve on the first inlet pipe, and the electric valve on the radiator inlet pipe are opened; the booster pump on the first outlet pipe is turned on; the medium flows back to the heat storage tank through the heat storage tank, the front and middle sections of the first outlet pipe, the radiator, and the rear section of the first inlet pipe, and is dissipated by the radiator until T4≥10℃, at which point the booster pump (c) on the first outlet pipe is turned off;

[0054] C. When T4≤5℃ and T2<30℃, the temperature difference between the medium and the equipment room is small, and the heat exchange efficiency is low. Temperature is adjusted by electric auxiliary heating. The electric valve on the first connecting pipe, the electric valve at the front end of the electric heating pipe, and the electric valve on the water inlet pipe of the radiator are opened. The three electric valves in the front, middle, and rear sections of the first outlet pipe and the electric valve on the first inlet pipe are closed. The heating rod in the electric heating pipe is energized, and the booster pump on the first outlet pipe is turned on. The medium forms a closed loop through the first connecting pipe, the electric heating pipe, the radiator, and a part of the first inlet pipe. The heating rod in the electric heating pipe heats the medium, and the radiator dissipates heat until T4≥10℃. Then, the booster pump on the first outlet pipe is turned off, and the heating rod in the electric heating pipe is de-energized.

[0055] 3) The step of storing and heating water in the intermediate water tank:

[0056] Before the intermediate water tank is filled with water and heated, T4 needs to be heated to 10°C, using the same method as the equipment room main body temperature adjustment steps, and then the intermediate water tank is filled with water and heated.

[0057] A. When T2≥40℃, the temperature difference between the medium in the heat storage tank and the water to be heated is large, resulting in high heat exchange efficiency. Therefore, the medium in the heat storage tank heats the water stored in the intermediate water tank. The three electric valves on the first outlet pipe and the electric valve on the first inlet pipe are opened, while the electric valve on the first connecting pipe, the electric valve at the front end of the electric heating pipe, and the electric valve on the radiator inlet pipe are closed. The booster pump on the first outlet pipe is started, thus forming a closed loop pipeline through the heat storage tank, the first outlet pipe, the heating vessel, and the first inlet pipe to heat the water stored in the intermediate water tank until T3≥20℃, at which point the booster pump on the first outlet pipe is turned off.

[0058] B. When T2 < 40℃, the temperature difference between the medium in the heat storage tank and the water to be heated is small, resulting in low heat exchange efficiency. Therefore, the electric heating rod in the electric heating pipe heats the water stored in the intermediate water tank by heating the medium. The two electric valves in the front middle section of the first outlet pipe, the electric valve on the first inlet pipe, and the electric valve on the radiator inlet pipe are closed. The electric valve in the rear section of the first outlet pipe and the electric valve on the first connecting pipe are opened. The heating rod in the electric heating pipe is energized, and the booster pump on the first outlet pipe is started. This forms a closed loop of the medium through the first connecting pipe, the electric heating pipe, the rear section of the first outlet pipe, the heating vessel, and the first inlet pipe, which heats the water stored in the intermediate water tank until T3 ≥ 20℃. At this point, the booster pump on the first outlet pipe is closed, and the heating rod in the electric heating pipe is de-energized.

[0059] 4) Dehumidification steps inside the main body of the equipment room:

[0060] Before dehumidifying the main body of the equipment room, T4 needs to be heated to 10°C, using the same method as the equipment room temperature adjustment steps.

[0061] When the humidity M1 ≥ 60%, the flow-blocking layer retracts, allowing airflow between the above-ground and underground parts of the equipment room. The first and second open-type fans are opened for 10-30 seconds. The cold air from outside entering through the lower first open-type fan sinks to the bottom of the equipment room due to its low density, while the hot and humid air inside rises due to its high density and is discharged through the higher second open-type fan. Then, the first and second open-type fans are closed, and the flow-blocking layer opens and fully covers the top of the equipment room.

[0062] The advantages and positive effects of this utility model are as follows: the reverse osmosis membrane water treatment equipment room in cold regions adopts a semi-underground form with cavities around the perimeter and a flow-blocking layer on the top to minimize cold bridges and 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 is heated at night without energy consumption; openable fans at different heights are set up, and the principle of cold air sinking and warm and humid air rising is used to quickly dehumidify, achieving rapid dehumidification of the insulated and sealed space; a separate circulating heating loop is used for the equipment placement space and the water to be treated by the reverse osmosis membrane to achieve precise temperature control, saving energy and significantly increasing the water production of the reverse osmosis membrane in cold regions during winter.
