Description

Technical Field

[0001] This utility model relates to the field of humidifier technology, specifically to a high-precision electrode humidifier and a pure water replenishment system for the electrode humidifier. Background Technology

[0002] Existing electrode humidifiers mainly consist of a humidification tank and electrodes placed inside the tank. When adjusting the humidification output, the electrode humidifier controls the current passing through the electrodes by adjusting the liquid level in the humidification tank, thereby changing the amount of heat generated by the electrodes and controlling the amount of steam produced. However, because the liquid level adjustment in the humidification tank is slow and unstable, the humidification output adjustment is delayed, and the control accuracy is relatively low, failing to meet the requirements for precise air humidification in laboratories, operating rooms, clean rooms, or biological laboratories. Utility Model Content

[0014] The present invention will be further described in detail below through specific embodiments:

[0015] like Figure 1 As shown in the figure, this utility model embodiment proposes a high-precision electrode humidifier, including an electrode humidification barrel body 1, a liquid level adjustment unit, and a humidification current pulse controller 2. The liquid level adjustment unit is connected to the electrode humidification barrel body 1 and is used to maintain a constant liquid level in the electrode humidification barrel body 1. The humidification current pulse controller 2 is connected to the electrode in the electrode humidification barrel body 1 and is used to adjust the energizing time of the electrode with pulses.

[0016] In this embodiment, the electrode humidification tank body 1 is the electrode humidifier described in the background art. This high-precision electrode humidifier mainly consists of the electrode humidification tank body 1, a liquid level adjustment unit, and a humidification current pulse controller 2. The liquid level adjustment unit maintains a constant liquid level inside the electrode humidification tank body 1, ensuring that the current value passing through the electrode remains constant. The humidification current pulse controller 2 adjusts the energizing time of the electrode with pulses to change the heating amount of the electrode humidification tank body 1, thereby controlling the amount of steam generated. Because the pulse adjustment of the heating amount of the electrode humidification tank body 1 is precise and rapid, the humidification control accuracy is significantly improved.

[0017] To better understand this solution, the liquid level control unit will be described in detail below. For example... Figure 1 As shown, according to another embodiment of the present invention, the high-precision electrode humidifier includes a liquid level adjustment unit comprising a liquid level gauge 3 and a water replenishment solenoid valve 5. The liquid level gauge 3 is disposed in the electrode humidification barrel body 1. The water replenishment solenoid valve 5 is disposed on the liquid replenishment pipe of the electrode humidification barrel body 1 and is connected to the liquid level gauge 3.

[0018] In this embodiment, the level gauge 3 detects the liquid level inside the electrode humidification tank body 1 in real time. When a change in the liquid level is detected, the level gauge controls the opening and closing of the water replenishment solenoid valve 5 to maintain a relatively constant liquid level inside the electrode humidification tank body 1. Specifically, the level gauge 3 feeds back the detected liquid level signal to the operation controller in the electrode humidification tank body 1, and the operation controller controls the opening and closing of the water replenishment solenoid valve 5.

[0019] To reduce the impact of the salt concentration of the liquid inside the electrode humidification tank 1 on the humidification current value passing through the electrode, such as... Figure 1 As shown, according to another embodiment of the present invention, the high-precision electrode humidifier is provided with a drain solenoid valve 4 on the drain pipe of the electrode humidification tank body 1, and the electrode is connected to a current transformer 6 that cooperates with the drain solenoid valve 4.

[0020] In this embodiment, the humidification current value passing through the electrode is detected by the current transformer 6. When the detected humidification current value is greater than the set value, the drain solenoid valve 4 and the water replenishment solenoid valve 5 are controlled to open, draining the high-salt liquid in the electrode humidification tank body 1 and replenishing it with low-salt liquid to adjust the salt concentration of the liquid in the electrode humidification tank body 1 to the preset concentration value. Then, the drain solenoid valve 4 and the water replenishment solenoid valve 5 are closed to ensure that the humidification current value remains relatively constant. Then, the humidification current pulse controller 2 adjusts the energization time of the electrode with pulses, thereby controlling the amount of steam generated from the humidification steam outlet of the electrode humidification tank body 1, so as to achieve precise control of the humidification amount.

[0021] The aforementioned high-precision electrode humidifier is applied to the pure water replenishment system of the electrode humidifier, such as... Figure 2 As shown, according to another embodiment of the present invention, the electrode humidifier pure water replenishment system includes a high-precision electrode humidifier as described in any of the above embodiments, to have its advantages.

[0022] Based on the above solution:

[0023] The pure water replenishment system of the electrode humidifier also includes a tap water pipe and a bypass pipe. The tap water pipe is connected to the replenishment pipe of the electrode humidifier body 1, and a pre-filter A, a water inlet solenoid valve B, a pressure pump C, and an RO membrane filter D are arranged sequentially from its inlet end to its outlet end on the tap water pipe. The front end of the bypass pipe is connected to the tap water pipe and is located between the pre-filter A and the water inlet solenoid valve B. The rear end of the bypass pipe is connected to the tap water pipe and is located between the RO membrane filter D and the replenishment pipe. A bypass solenoid valve G is installed on the bypass pipe.

[0024] In this embodiment, it is used as follows:

[0025] Open the inlet solenoid valve B and close the bypass solenoid valve G, then start the booster pump C. Tap water is introduced into the tap water pipeline and passes through the pre-filter A, inlet solenoid valve B, booster pump C, and RO membrane filter D in sequence. The pre-filter A performs a first filtration of the tap water, and the RO membrane filter D performs a second filtration of the tap water, purifying the tap water into pure water. The pure water then enters the electrode humidification tank body 1 for use.

[0026] When insufficient salt content is detected in the electrode humidification tank body 1 (this information is obtained through the humidification current value of the electrode), the inlet solenoid valve B and the pressure pump C are closed, and the bypass solenoid valve G is opened; tap water is introduced through the tap water pipe and directly introduced into the electrode humidification tank body 1 through the bypass pipe. When sufficient salt content is detected in the electrode humidification tank body 1 and the humidification current value of the electrode reaches the set value, the inlet solenoid valve B is opened and the bypass solenoid valve G is closed, the pressure pump C is started, and the supply of pure water to the electrode humidification tank body 1 is restored, making it possible for the electrode humidifier to use pure water for humidification, and also completely solving the problem of severe scaling in the electrode humidifier.

[0027] To improve the utilization rate of RO membrane filters for wastewater generated during tap water purification, such as... Figure 2 As shown, according to another embodiment of the present invention, in the pure water replenishment system of the electrode humidifier, a waste liquid discharge and recycling unit is connected between the inlet end of the RO membrane filter D and the pressurization pump C. The waste liquid discharge and recycling unit is used to discharge and return the wastewater generated by the RO membrane filter D for reuse.

[0028] Specifically, the wastewater discharge and recycling unit includes a wastewater discharge pipe and a circulation pipe. One end of the wastewater discharge pipe is connected to the wastewater outlet of the RO membrane filter D and a wastewater flow restrictor J is installed on it. The rear end of the circulation pipe is connected to the inlet end of the booster pump C and its front end is connected to the wastewater discharge pipe and located in front of the wastewater flow restrictor J. A re-filtration check valve I and a re-filtration flow restrictor H are arranged sequentially on the circulation pipe in the direction of water flow.

[0029] Here, the amount of wastewater generated by the RO membrane filter D discharged from the wastewater outlet pipe and returned through the circulation pipe for reuse is adjusted by the wastewater flow restrictor J and the re-filtration flow restrictor H respectively. The re-filtration check valve I prevents the water in the circulation pipe from flowing backward, ensuring that the wastewater flows back through the circulation pipe to the inlet end of the pressure pump C and is then pumped into the RO membrane filter D for purification and reuse.

[0030] In order to stably supply water to the electrode humidification tank body 1, such as Figure 2 As shown, according to another embodiment of the present invention, in the pure water replenishment system of the electrode humidifier, an expansion tank F is provided on the tap water pipeline between the replenishment pipe and the RO membrane filter D, and the rear end of the bypass pipe is located in front of the expansion tank F.

[0031] In this embodiment, the purified water formed after purification by the RO membrane filter D or the tap water discharged through the bypass pipe is pressure stabilized by the expansion tank F to ensure that the water pressure introduced into the electrode humidification tank body 1 by the replenishment pipe is stable.

[0032] Based on the above solution:

[0033] A main check valve E is installed on the tap water pipeline, located between the rear end of the bypass pipe and the RO membrane filter D. This prevents tap water supplied through the bypass pipe from entering the RO membrane filter D when the bypass pipe is supplying water.

[0034] The expansion tank F is equipped with a water intake pipe at its front end and a water intake valve on the water intake pipe to facilitate water intake for analysis of the water quality in the expansion tank F.

[0035] In this embodiment, the electrode humidifier pure water replenishment system also includes a housing K, and the above structures are all arranged inside the housing K to form a humidifier device.

[0036] When the purified water replenishment system of this electrode humidifier is in normal use:

[0037] Open the inlet solenoid valve B and close the bypass solenoid valve G. Start the booster pump C. After the tap water passes through the pre-filter A, it passes through the inlet solenoid valve B and is then pressurized by the booster pump C to enter the RO membrane filter D. The purified water that comes out passes through the main check valve E and enters the makeup liquid pipe. The expansion tank F is used to stabilize the supply pressure of the purified water. Part of the wastewater produced by the RO membrane filter D is discharged through the wastewater discharge pipe, and the other part passes through the re-filtration check valve I and the re-filtration flow restrictor H in the circulation pipe and returns to the inlet of the booster pump C for reuse.

[0038] When the salt content in the electrode humidification tank body 1 is detected to be insufficient, the bypass solenoid valve G opens, the inlet solenoid valve B and the pressure pump C close, and tap water is directly added to the electrode humidification tank body 1 through the replenishment pipe. When the salt content in the electrode humidification tank body 1 is sufficient to make the humidification current value reach the set value, the inlet solenoid valve B and the pressure pump C are opened and the bypass solenoid valve G is closed to restore the pure water replenishment.

[0039] It should be noted that all electrical components in this solution are existing structures, and as long as they meet the usage requirements, they are sufficient. Detailed component models will not be provided here.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
