Description

Technical Field

[0001] The utility model relates to the technical field of gas manufacturing equipment, in particular to an intermittent electrolytic cell side wall blowing and heat dissipation system. Background Art

[0002] The existing electrolytic cells are mostly old and account for 60%. The risk of sidewalls is increasing day by day. It is necessary to cool the sidewalls. Lowering the temperature of the electrolytic cell sidewalls can improve the efficiency and safety of the electrolysis process. The following are some possible methods:

[0003] 1. Cooling system: A cooling system is installed to reduce the sidewall temperature by circulating cooling liquid or gas.

[0004] 2. Insulation material: Use efficient insulation material to wrap the electrolytic cell to reduce heat conduction.

[0005] 3. Thermal insulation layer: Add thermal insulation layer on the side wall of the electrolytic cell to reduce the heat transfer to the side wall.

[0006] 4. Optimize the electrolysis process: Improve the parameters of the electrolysis process, such as current density and electrolyte temperature, to reduce heat generation.

[0007] 5. Heat recovery: Implement a heat recovery system to reuse the generated heat and reduce the side wall temperature.

[0008] 6. Control operating temperature: Ensure operation within the appropriate temperature range to avoid overheating.

However, the long-term blowing of the blowpipe cannot achieve 100% utilization of wind energy and is often in an uncontrollable state, causing energy waste. The blowpipe used for cooling the electrolytic cell in the prior art cannot be turned on and off regularly, causing energy waste. Utility Model Content

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] The utility model aims to provide an intermittent electrolytic cell side wall air blowing heat dissipation system, which realizes intermittent air blowing on the electrolytic cell side wall by setting a timer at the power supply end of the solenoid valve, thereby improving the heat dissipation efficiency of the air blowing pipe.

[0039] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] Embodiment 1

[0041] like Figure 1 As shown, the utility model provides an intermittent electrolytic cell side wall air blowing heat dissipation system, the system comprising: a gas storage tank 2, a solenoid valve 5, a timer 6 and a blowing pipe 9.

[0042] The air inlet of the air storage tank 2 is connected to the compressed air pipeline, the air outlet of the air storage tank 2 is connected to the air inlet of the solenoid valve 5, and the air outlet of the solenoid valve 5 is connected to the air inlet of the blowing pipe 9; the air outlet of the blowing pipe 9 is arranged on the side of the electrolytic cell.

[0043] The output end of the timer 6 is electrically connected to the power supply end of the electromagnetic valve 5. The timer 6 is used to open and close the electromagnetic valve 5 at a fixed time, so as to achieve the fixed time blowing of the blowing slot air duct 9, which can effectively reduce energy saving.

[0044] As an optional implementation, the system further includes: a check valve 3 .

[0045] The check valve 3 is located between the gas storage tank 2 and the solenoid valve 5 , and the check valve 3 is used to prevent gas from flowing back.

[0046] As an optional implementation, the system further includes: a flow-dividing gas control device 4 ; the flow-dividing gas control device 4 is located between the check valve 3 and the solenoid valve 5 .

[0047] As an optional implementation, the flow splitting air control device 4 specifically includes: a pressure control valve 41, a second air filter pressure reducing valve 42, a third air filter pressure reducing valve 43 and a two-position five-way pneumatic valve 44;

[0048] The air inlet of the pressure control valve 41 is connected to the air outlet of the check valve 3, and the air outlet of the pressure control valve 41 is connected to the air inlet of the second air filter pressure reducing valve 42. The pressure control valve 41 is used to open the pipeline when the pressure reaches a preset pressure.

[0049] The model of the pressure control valve 41 is CY400, and the preset pressure is 0.4MPa. When the wind pressure is lower than 0.4MPa, the pressure control valve 41 does not work, the two-position five-way pneumatic valve 44 is in a non-working state, the compressed air does not supply air to the solenoid valve 5, and intermittent blowing is not performed; when the pressure is greater than 0.4MPa, the pressure control valve 41 is opened, the two-position five-way pneumatic valve 44 is switched to a working state, and the compressed air supplies air to the solenoid valve 5 to achieve intermittent blowing.

[0050] The air outlet of the second air filter pressure reducing valve 42 is respectively connected to the A port and B port air circuits of the two-position five-way pneumatic valve 44; the air inlet of the third air filter pressure reducing valve 43 is connected to the air outlet of the check valve 3, and the air outlet of the third air filter pressure reducing valve 43 is respectively connected to the R1 port and R2 port air circuits of the two-position five-way pneumatic valve 44; the air inlet of the solenoid valve 5 is connected to the P port air circuit of the two-position five-way pneumatic valve 44.

[0051] The models of the first air filter pressure reducing valve 1, the second air filter pressure reducing valve 42 and the third air filter pressure reducing valve 43 are all LFR-1 / 4-D-MIDI; the model of the two-position five-way pneumatic valve 44 is VL-5-1 / 49199.

[0052] An air filter pressure reducing valve is a device used to control the pressure in a gas system. It is usually used to reduce high-pressure gas to a lower working pressure and remove impurities in the air through the filter. The air filter pressure reducing valve can perform pressure regulation and air filtration. Pressure regulation is achieved through the air filter. The main function of the pressure reducing valve is to reduce the input high-pressure gas to the required working pressure; air filtration is used to remove particulate matter and impurities in the air to protect subsequent equipment from contamination.

[0053] After being compressed, the compressed air is stored in the air storage tank 2 through the air filter pressure reducing valve, the pressure control valve 41, the air filter valve, the pressure reducing valve, and the two-position five-way air hole valve, which is connected to the blowing pipe 9 through the quick connector 8, and the air in the pipeline is diverted into the two-position five-way pneumatic valve 44, which provides more control and operation flexibility and is suitable for various applications that require multifunctional gas flow regulation. Specifically, the two-position five-way pneumatic valve 44 has the following advantages:

[0054] 1. Flow control: By diverting the air to a two-position five-way pneumatic valve, the flow of the two gas flow channels can be independently controlled. This is very useful for applications that require separate control of different flow directions, such as controlling multiple actuators in a hydraulic or pneumatic system.

[0055] 2. Direction control: The two-position five-way pneumatic valve allows the flow direction of the gas to be switched.

[0056] 3. Dual control: By diverting and controlling the two-position five-way pneumatic valve, redundant control can be achieved to improve the reliability of the system. If one valve fails, the other valve can still be used to control the gas flow.

[0057] 4. Multi-task operation: When multiple different tasks need to be performed in the same system, each task requires a different gas flow pattern. The two-position five-way pneumatic valve can meet these needs without having to change the pipeline connection.

[0058] 5. Safety: By diverting the gas and controlling two valves, you can more easily perform maintenance, repairs or emergency shutdown operations to ensure the safety of the system.

[0059] As an optional implementation, the system further includes: a first air filtering pressure reducing valve 1 .

[0060] The first air filtering and reducing valve 1 is located between the compressed air pipeline and the air storage tank 2; the first air filtering and reducing valve 1 is used to reduce the pressure and filter the incoming compressed air.

[0061] As an optional implementation, the system further includes: a stop valve 7 .

[0062] The stop valve 7 is located between the solenoid valve 5 and the blowing pipe 9, and the stop valve 7 is used to manually open and close the pipeline.

[0063] As an optional implementation, the stop valve 7 is connected to the air inlet of the blowing pipe 9 via a quick connector 8 .

[0064] The utility model realizes intermittent blowing of the side wall of the electrolytic cell by arranging a timer at the power supply end of the electromagnetic valve, thereby improving the heat dissipation efficiency of the blowing pipe.

[0065] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0066] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. At the same time, for those skilled in the art, according to the ideas of the utility model, there will be changes in the specific implementation methods and application scope.
