Description

Technical Field

[0001] The invention relates to the technical field of air dehumidification, in particular to a membrane dehumidifier with an anti-clogging function. Background Art

[0002] Humidity is an important indicator for measuring indoor air quality and has a significant impact on human comfort, production processes and product quality. At the same time, environmental humidity also has strict requirements in lithium battery manufacturing, pharmaceuticals, food and other fields. It is usually necessary to maintain a low-humidity environment to ensure the life, quality and safety of the product. Excessive humidity will not only cause metal corrosion and deterioration of food and medicine, but also affect human comfort and health.

[0003] Most conventional dehumidifiers directly draw external air into the interior through pipes for dehumidification. During this process, if the inhaled air contains a lot of moisture, the moisture will carry the dust in the air and adhere to the pipe. Over time, it may cause blockage of the suction pipe, affecting the entry of air. If the air contains fewer water molecules, during the dehumidification process, it may reach the standard for input into the room halfway through, but the entire dehumidification path still needs to be completed, resulting in useless dehumidification in the second half and low efficiency. Summary of the Invention

[0004] The object of the present invention is to provide a membrane dehumidifier with an anti-clogging function to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] The membrane dehumidifier is used to filter water molecules in the air. The membrane dehumidifier includes a dehumidifier body, an anti-clogging mechanism and a path adjustment mechanism. The dehumidifier body is connected to the anti-clogging mechanism, and the dehumidifier body is connected to the path adjustment mechanism.

[0007] In a membrane dehumidifier, the device is used to filter out most of the water molecules in the air. The air with most of the water molecules filtered out can be used in fields with high humidity requirements such as lithium battery manufacturing, pharmaceuticals, and food. The dehumidifier body is used to provide a place for gas dehumidification, filtering out the water molecules in the imported air and then exporting them. The anti-clogging mechanism is used to heat the pipe when the air is input to evaporate the water molecules in the imported air, preventing the dust carried in the air from adhering to the pipe and causing blockage of the pipe. The path adjustment mechanism detects the water molecules in the air being dehumidified, and adjusts the path for direct output for air that has completed dehumidification in advance.

After the concentrated dehumidification solution completes the dehumidification of the air, the dehumidified dehumidification solution absorbs water molecules so that the concentration becomes lower, so that it flows through the heater for heating, and after being heated to the temperature required for regeneration, it flows into the regenerator for concentrated regeneration. The dehumidification solution after the regenerator is restored to a concentrated solution. At this time, the solution temperature is high and the dehumidification efficiency is low. It flows through the cooler for cooling, and finally flows into the liquid reservoir for storage and waiting for dehumidification again, completing the cycle and realizing the recycling of the concentrated dehumidification solution. The outdoor fresh air is sent into the membrane dehumidifier with a serpentine flow channel with a sinusoidal wall by the induced draft fan. After being dehumidified by the dehumidification solution, it flows into the indoor use.

[0010] Furthermore, the membrane dehumidifier includes an upper shell and a lower shell, the upper shell and the lower shell are separated by a selective semipermeable membrane, the membrane dehumidifier is connected to the inclined tube, the upper shell is connected to the inclined tube, an air flow channel is provided in the upper shell, an air inlet and an air outlet are respectively provided on the opposite side surfaces of the upper shell, the air inlet, the air outlet and the air flow channel are connected, the air inlet is connected to the inclined tube at one end away from the air flow channel and is connected to the gas outlet, the lower shell is connected to the liquid reservoir, the lower shell is connected to the heater, a solution flow channel is provided in the lower shell, a liquid inlet and a liquid outlet are respectively provided on the opposite side surfaces of the lower shell, the liquid inlet, the liquid outlet and the solution flow channel are connected, the liquid inlet and the liquid reservoir are connected through a pipe, the liquid outlet and the heater are connected through a pipe, the wall surfaces of the air flow channel and the solution flow channel are both sinusoidal, and cuttlefish fin-shaped waveform flow blocks are periodically provided at the bottom of the air flow channel and the solution flow channel.

[0011] In the membrane dehumidifier, the upper shell and the lower shell are used to circulate air and concentrated dehumidification solution respectively. The outside air enters the air flow channel through the air inlet and flows out along the air flow channel to the air outlet. The concentrated dehumidification solution enters the solution flow channel through the liquid inlet and flows out along the solution flow channel to the liquid outlet. In this process, the flow direction of the concentrated dehumidification solution is opposite to the flow direction of the air. The wall surfaces of the solution flow channel and the air flow channel are sinusoidal. The air enters the air flow channel and flows in a serpentine shape, forming a countercurrent or quasi-countercurrent with the solution flow, which has a higher mass transfer efficiency. The bottom of the solution flow channel and the air flow channel are periodically provided with cuttlefish fin-shaped wave-shaped flow blocks, which can further enhance the fluid disturbance in the flow channel and improve the heat exchange efficiency.

[0012] Furthermore, the anti-blocking mechanism includes a heating device, which is placed in the working chamber and connected to the gas inlet. The heating device includes an induction coil and an inclined tube. The induction coil and the inclined tube are placed in the working chamber. The inclined tube is a metal tube. One end of the inclined tube is connected to the gas inlet. The induction coil is sleeved on the outer periphery of the inclined tube. The heating device is connected to the dehumidifier body, and the inclined tube is connected to the dehumidifier body. The anti-blocking mechanism also includes a collecting device, which is placed in the working chamber, the collecting device is connected to the heating device, and the inclined tube is connected to the collecting device. The collecting device includes a collecting tube and a water storage tank. The collecting tube and the water storage tank are placed in the working chamber, one end of the collecting tube is connected to the bottom of the inclined tube near the gas inlet, and the end of the collecting tube away from the inclined tube is connected to the water storage tank.

[0013] In the anti-clogging mechanism, the mechanism is used to heat the introduced air, so that most of the water molecules evaporate, and the water molecules and dust are separated, to prevent the dust from containing more water molecules and adhering to the pipe, which will cause the pipe to be blocked in the long run. The heating device is used to heat the inclined pipe, and the induction coil is wound around the outer periphery of the inclined pipe. After the power is turned on, current is passed through the induction coil to generate a high-frequency electromagnetic field. The electromagnetic field generates eddy currents in the pipe, and the eddy current flow generates heat, causing the inclined pipe to heat up. After the air enters the inclined pipe from the gas inlet, the water molecules in the air will evaporate, so that the water molecules and the dust entrained in the air are separated, and will not adhere to the pipe due to excessive water molecules. At the same time, through heating, the water molecules in the air can be initially dehumidified. After stopping work, the inside of the inclined pipe returns to normal temperature, and the evaporated water molecules are liquefied when cooled. The inclined pipe is placed at an angle, and the water molecules flow through the inclined pipe to the collection pipe below and finally flow into the water storage tank.

[0014] Furthermore, the path adjustment mechanism includes a humidity detection device, the path adjustment mechanism is connected to the membrane dehumidifier, the humidity detection device is connected to the membrane dehumidifier, the humidity detection device is connected to the upper shell, the humidity detection device is connected to the air flow channel, the humidity detection device includes a metal electrode plate and a metal oxide sheet, the metal electrode plate is placed in the middle section of the air flow channel, two metal electrodes are provided, the two metal electrodes are tightly connected to the air flow channel, the metal oxide sheet is tightly connected to the middle section of the air flow channel, the metal electrode plate and the metal oxide sheet are parallel, the path adjustment mechanism also includes a cut-off device, the cut-off device is connected to the membrane dehumidifier, the cut-off device is connected to the upper shell, the cut-off device is connected to the air flow channel, the cut-off device is connected to the air outlet, the cut-off device is placed on the side of the humidity detection device away from the air inlet, the cut-off device includes a regulating valve, an air guide pipe and a push plate, a through hole is provided at the top of the air flow channel, one end of the air guide pipe is connected to the air flow channel through hole, the other end of the air guide pipe is connected to the air outlet, the bottom of the push plate is hinged to the bottom wall of the air flow channel, and the top of the push plate and the air flow channel are slidably connected by a telescopic rod.

[0015] In the path adjustment mechanism, the mechanism is placed in the middle of the air flow channel, and the humidity detection device is used to detect the humidity of the air in the middle of the air flow channel. Two metal plates are placed on both sides and a metal oxide sheet is placed in the middle. After the power supply is connected, during the flow of air, the metal oxide sheet absorbs moisture, causing the dielectric constant to change, and then the capacitance value to change. When more moisture is absorbed, the capacitance value increases, and when less moisture is absorbed, it decreases. The humidity is determined based on the change. If the capacitance value does not change much, the regulating valve is opened, the telescopic rod is extended to make the push plate stand up, the air flow channel is disconnected, and the gas flows directly to the air outlet through the air duct. If the capacitance value increases a lot, the regulating valve remains closed, and the gas continues to pass through the air flow channel for dehumidification. The water molecules are absorbed by the concentrated dehumidification solution through the selective semipermeable membrane, and flow into the room from the gas outlet after reaching the air outlet.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention filters and absorbs water molecules in the external air through the dehumidifier body, and then flows into the room, and realizes anti-clogging in the pipe by setting an anti-clogging mechanism. In the process of air entering the air inlet through the gas inlet, an inclined pipe is set, and an induction coil is arranged on the periphery of the inclined pipe. After power is turned on, the temperature inside the inclined pipe is increased, so that the air passing through this section is heated, the water molecules evaporate, and the water molecules and dust in the air are separated, so as to avoid the dust in the air being entrained by water at room temperature and adhering to the inner wall of the pipe, which will cause pipe blockage in the long run and affect the dehumidification efficiency. At the same time, the water molecules in the heated air are initially filtered out. In addition, it can improve the subsequent dehumidification efficiency. By setting a path adjustment mechanism, the air flowing through the middle of the air flow channel is detected, and the water molecules in the air are detected through the metal plate and the metal oxide sheet. If the capacitance value does not change much, the regulating valve is opened, and the gas flows directly to the air outlet through the air duct. If the capacitance value increases significantly, the regulating valve remains closed, and the gas continues to pass through the air flow channel for dehumidification. The water molecules are absorbed by the concentrated dehumidification solution through the selective semipermeable membrane, and after reaching the air outlet, they flow into the room through the gas outlet, thereby realizing adjustable path in the dehumidification process and improving dehumidification efficiency. The concentrated dehumidification solution is then recycled through the heater, regenerator, cooler and liquid reservoir. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Working principle of the present invention: The present invention filters and absorbs water molecules in the external air through the dehumidifier body 1, and then flows into the room. By setting an anti-clogging mechanism 2, anti-clogging in the pipeline is achieved. In the process of air entering the air inlet 1412 through the gas inlet 112, an inclined tube 212 is set. The induction coil 211 is arranged on the periphery of the inclined tube 212. After power is turned on, the temperature inside the inclined tube 212 is increased, so that the air passing through this section is heated, the water molecules evaporate, and the water molecules and dust in the air are separated, so as to avoid the dust in the air being entrained by water at room temperature and adhering to the inner wall of the pipeline, which will cause pipeline blockage in the long run and affect the dehumidification efficiency.

By setting the path The diameter adjustment mechanism 3 detects the air flowing through the middle of the air flow channel 1411, and detects the water molecules in the air through the metal electrode 311 and the metal oxide sheet 312. If the capacitance value does not change much, the regulating valve 321 is opened, and the gas flows directly to the air outlet 1413 through the air guide tube 322. If the capacitance value increases significantly, the regulating valve 321 remains closed, and the gas continues to pass through the air flow channel 1411 for dehumidification. The water molecules are absorbed by the concentrated dehumidification solution through the selective semipermeable membrane, and after reaching the air outlet 1413, they flow into the room through the gas outlet 113, thereby realizing the adjustable path during the dehumidification process and improving the dehumidification efficiency. The concentrated dehumidification solution is then recycled through the heater 124, the regenerator 121, the cooler 122 and the liquid reservoir 123.
