Description

Technical Field

[0001] The present invention relates to a drying device, and more specifically to a gas drying device with an automatic alarm function. Background Art

[0002] During the process of producing hydrogen by electrolyzing water, due to factors such as the occurrence of electrolysis reaction and the pressure-resistant and airtight structure of the electrolytic cell, the temperature of the electrolyte in the electrolytic cell will continue to rise. As the temperature rises, the content of water vapor in the hydrogen and oxygen gas generated by electrolysis and the alkaline components in the electrolyte will increase, which has a negative impact on the service performance of the hydrogen and oxygen gas. The prior art generally uses the principle of condensation to reduce the content of water vapor and alkaline components in the hydrogen and oxygen gas, but this method cannot completely remove the water vapor in the hydrogen and oxygen gas. The water vapor condenses into water droplets, and as the water droplets accumulate, it will affect the service performance of the hydrogen and oxygen gas. In addition, the existing drying device has a single structure, and there are defects such as too short contact path between the desiccant and the gas, low drying efficiency, short replacement cycle of the desiccant, and inability to predict the failure of the desiccant.

By increasing the surface roughness of the water electrolysis plate 401.3, the contact surface area between the water electrolysis plate 401.3 and the electrolyte is increased, the gas production efficiency is improved, and at the same time the external dimension of the water electrolysis plate 401.3 is reduced to meet the requirement of product miniaturization;

[0068] A water electrolysis plate installation area 401.3.7 is provided on the outer circle of the electrolysis area 401.3.5, and a plurality of water electrolysis plate installation holes 401.3.8 are evenly opened in the water electrolysis plate installation area 401.3.7 along the circumferential direction of the water electrolysis plate body 401.3.1.

At the same time, since the electrolyzer gasket 401.4 is one circle larger than the outer shape of the electrolyzer plate 401.3, the electrolyzer plate 401.3 can be completely wrapped during mutual extrusion, avoiding short circuit phenomena between multiple electrolyzer plates 401.3, realizing the overall waterproof requirement of the electrolyzer 401, and improving safety and reliability.

To ensure a stable anti-slosh effect, one or two additional layers of the first anti-slosh partition fins 402.5 and the second anti-slosh partition fins 402.6 of the circulating liquid storage tank can be added above the circulating liquid storage tank mesh partition plates 402.7 or within the liquid level fluctuation range.

The top end of the circulating liquid storage tank liquid filling pipe 402.13 is located in the upper section of the circulating liquid storage tank storage chamber 402.3 on the left side, that is, above the liquid level, effectively avoiding the liquid level fluctuation caused by the liquid surging during liquid filling.

[0074] A circulating liquid storage tank pressure sensor 402.14 is also provided inside the circulating liquid storage tank 402.

[0075] The working principle of the circulating liquid storage tank 402: In the normal working state, the circulating liquid storage tank 402 holds electrolyte equal to 2 / 3 of its volume. The hydrogen and oxygen gases generated by the electrolysis of water carry the electrolyte and enter the circulating liquid storage tank 402 through the circulating liquid storage tank air inlet 402.8. The hydrogen and oxygen gases pass through the electrolyte in the circulating liquid storage tank 402 and are output through the circulating liquid storage tank air outlet 402.9. The electrolyte stored in the circulating liquid storage tank 402 under the action of gravity outputs liquid to the liquid replenishing tank 405 through the circulating liquid storage tank liquid outlet 402.10. When the vehicle is moving continuously, the circulating liquid storage tank 402 can prevent the liquid contained in the tank from shaking and the liquid level from fluctuating, avoiding the liquid from overflowing into other pipelines, and ensuring the stability of the pressure and liquid level in the circulating liquid storage tank, thereby avoiding the signal error of the circulating liquid storage tank liquid level sensor 402.12.

A gas cooling and water filtering device air inlet 403.2 is provided at the lower part of the right side surface of the gas cooling and water filtering device tank body 403.1. A gas cooling and water filtering device air outlet 403.3 is provided at the upper part of the left side surface of the gas cooling and water filtering device tank body 403.1. A gas cooling and water filtering device liquid return port 403.4 is provided at the bottom of the gas cooling and water filtering device tank body 403.1.

The gas cooling and water filtering device heat dissipation fins 403.5 promote the rapid heat dissipation of the gas cooling and water filtering device tank body 403.1. When the relatively high-temperature hydrogen-oxygen gas flows through the relatively low-temperature gas cooling and water filtering device wire mesh 403.6 inside the gas cooling and water filtering device tank body 403.1, the water vapor in the hydrogen-oxygen gas condenses into water droplets on the surface of the dense gas cooling and water filtering device wire mesh 403.6. The water droplets gather together under the action of gravity and are output through the gas cooling and water filtering device liquid return port 403.4. The gas cooling and water filtering device 403 is small in size, simple in structure, and easy to process, can reduce the content of water vapor and alkaline components in the hydrogen-oxygen gas, and does not require an additional storage device to export and cool the hydrogen-oxygen gas, thus reducing the occupied space.

[0081] A horizontal first partition plate 404.18 of the gas drying device is provided at the bottom section of the central gas chamber 404.4 of the gas drying device.

The fourth partition plate 404.21 of the gas drying device divides the inner cavity of the air outlet chamber 404.13 of the gas drying device into an upper cavity and a lower cavity; Multiple air holes are formed on the surfaces of the third partition plate 404.20 and the fourth partition plate 404.21 of the gas drying device. Desiccants are placed in the inner cavity of the gas chamber 404.14 of the gas drying device and the lower cavity of the air outlet chamber 404.13 of the gas drying device;

[0082] When the staff places the desiccant into the kettle body 404.1 of the gas drying device, the kettle body 404.1 of the gas drying device needs to be placed upside down. The first partition plate 404.18 of the gas drying device is used to block the desiccant from entering the central gas chamber 404.4 of the gas drying device. The second partition plate 404.19 of the gas drying device makes the air inlet chamber 404.12 of the gas drying device form an independent water accumulation space and blocks the desiccant from entering the air inlet chamber 404.12 of the gas drying device. The fourth partition plate 404.21 of the gas drying device is used to block the desiccant from entering the upper cavity of the air outlet chamber 404.13 of the gas drying device to prevent the desiccant from blocking the air outlet 404.6 of the gas drying device. The third partition plate 404.20 of the gas drying device is used to block the desiccant in the corresponding gas chamber 404.14 of the gas drying device from entering the air inlet chamber 404.12 of the gas drying device to avoid the desiccant from blocking the air inlet 404.5 of the gas drying device;

[0083] Gas drying device gaskets 404.22 are provided between the top end and the bottom end of the kettle body 404.1 of the gas drying device and the upper kettle lid 404.2 and the lower kettle lid 404.3 of the gas drying device respectively;

[0084] Sealing strips 404.23 of the gas drying device are provided on the upper and lower end faces of the central gas chamber 404.4, the inlet gas chamber 404.12, the outlet gas chamber 404.13 and the gas chamber 404.14 of the gas drying device.

[0085] The working principle of the gas drying device 404: The hydrogen-oxygen gas with water vapor enters the inlet gas chamber 404.12 of the gas drying device through the gas drying device inlet 404.5. Part of the water vapor condenses into small water droplets and deposits in the inlet gas chamber 404.12 of the gas drying device. The hydrogen-oxygen gas with water vapor flows through the gas chamber 404.14 at the rear section of the gas drying device body 404.1 in an S shape successively up and down through the first notch 404.10 and the second notch 404.11 of the gas drying device, and then enters the central gas chamber 404.4 of the gas drying device through the fourth notch 404.16 of the gas drying device, and enters the gas chamber 404.14 adjacent to the front side of the inlet gas chamber 404.12 of the gas drying device through the third notch 404.15 of the gas drying device, and flows through the gas chamber 404.14 at the front section of the gas drying device body 404.1 in an S shape successively up and down through the first notch 404.10 and the second notch 404.11 of the gas drying device, and finally enters the outlet gas chamber 404.13 of the gas drying device and is output through the gas drying device outlet 404.6. When the desiccant fails or the drying capacity is insufficient, the water vapor in the hydrogen-oxygen gas cannot be sucked out in time. After a long time, the water level in the central gas chamber 404.4 of the gas drying device gradually rises. When the float in the liquid level sensor 404.17 of the gas drying device reaches the high liquid level, the liquid level sensor 404.17 of the gas drying device feeds back the signal to the control unit 100, starts the alarm function and triggers further protection measures. The gas drying device 404 has two functions of gas drying and failure alarm. While ensuring a small volume, it increases the effective path and area of contact between the desiccant and the gas, extends the replacement cycle of the desiccant, and its structural design is convenient for replacing the desiccant. When the desiccant fails or the drying capacity is insufficient, it can automatically alarm and trigger further protection measures.

A liquid replenishing tank water injection port 405.2 is provided at the top of the liquid replenishing tank body 405.1. A liquid replenishing tank water outlet 405.3 is provided at the lower section of the liquid replenishing tank body 405.1. A cooling spiral tube 405.4 is arranged in the inner cavity of the liquid replenishing tank body 405.1 from top to bottom. The upper port of the cooling spiral tube 405.4 is set as a cooling spiral tube liquid inlet 405.5, and the upper port of the cooling spiral tube 405.4 extends out of the upper section of the liquid replenishing tank body 405.1.

[0089] A first pipeline is connected between the water electrolysis cell gas outlet 401.11 and the circulation storage tank gas inlet 402.8.

A fourth pipeline is connected among the gas cooling and water filtering device liquid return port 403.4, the circulation storage tank liquid outlet 402.10 and the cooling spiral tube liquid inlet 405.5. A fifth pipeline is connected between the cooling spiral tube liquid outlet 405.6 and the water electrolysis cell liquid return port 401.9.

[0090] The working principle of a fuel-saving and emission-reducing device for a vehicle internal combustion engine:

[0091] The water electrolyzer 401 starts electrolyzing water and promptly generates hydrogen-oxygen gas with water vapor. The hydrogen-oxygen gas with water vapor accumulates towards the top and enters the circulation liquid storage tank 402 through the first pipeline from the gas outlet 401.11 of the water electrolyzer and the inlet 402.8 of the circulation liquid storage tank. It passes through the electrolyte in the circulation liquid storage tank 402, accumulates at the top inside the circulation liquid storage tank 402, and then enters the gas cooling and water filtering device 403 through the second pipeline from the gas outlet 402.9 of the circulation liquid storage tank and the inlet 403.2 of the gas cooling and water filtering device. After cooling, the hydrogen-oxygen gas enters the gas drying device 404 through the third pipeline from the gas outlet 403.3 of the gas cooling and water filtering device and the inlet 404.5 of the gas drying device. The hydrogen-oxygen gas is dried by the desiccant in the drying device 404, and the dried hydrogen-oxygen gas is output into the intake pipeline of the engine 102 through the gas outlet 404.6 of the gas drying device and finally enters the engine cylinder with the air;

[0092] When the hydrogen-oxygen gas with water vapor enters the gas cooling and water filtering device 403, the water vapor condenses into liquid upon cooling, accumulates at the bottom of the gas cooling and water filtering device 403, and enters the cooling spiral tube 405.4 through the fourth pipeline from the liquid return port 403.4 of the gas cooling and water filtering device and the inlet 405.5 of the cooling spiral tube. It then returns to the water electrolyzer 401 through the fifth pipeline from the outlet 405.6 of the cooling spiral tube and the liquid return port 401.9 of the water electrolyzer;

[0093] During the electrochemical reaction process of water electrolysis, a large amount of heat energy is released, causing the temperature of the electrolyte in the water electrolyzer 401 to continuously rise. When the hydrogen-oxygen gas generated in the water electrolyzer 401 enters the circulation liquid storage tank 402 through the first pipeline from the gas outlet 401.11 of the water electrolyzer and the inlet 402.8 of the circulation liquid storage tank, due to the internal pressure and air flow in the water electrolyzer 401, the high-temperature electrolyte in the upper part of the water electrolyzer 401 is carried into the circulation liquid storage tank 402 in the form of a gas-liquid mixture. After the electrolyte in the circulation liquid storage tank 402 is slightly cooled, under the action of its own gravity, it enters the cooling spiral tube 405.4 through the fourth pipeline from the liquid outlet 402.10 of the circulation liquid storage tank and the inlet 405.5 of the cooling spiral tube. Since the replenishing tank 405 is filled with normal-temperature raw water, it can fully cool the high-temperature electrolyte in the cooling spiral tube 405.4. The cooled electrolyte returns to the water electrolyzer 401 through the fifth pipeline from the outlet 405.6 of the cooling spiral tube and the liquid return port 401.9 of the water electrolyzer for electrolysis reaction. Such continuous cyclic cooling is carried out.

[0094] As the electrolysis reaction continues, the electrolyte in the water electrolytic cell 401 is continuously consumed, causing the electrolyte level in the circulating liquid storage tank 402 to continuously drop. When the electrolyte level drops to a set low level, an alarm signal is triggered, and the control unit 200 controls the water pump 407 to start, and at the same time controls the electric stop valve 408 to open, and the room temperature raw water in the replenishment tank 405 is pumped into the circulating liquid storage tank 402 through the replenishment tank outlet 405.3 and the seventh pipeline from the bottom end of the circulating liquid storage tank replenishment pipe 402.13. As the liquid level in the circulating liquid storage tank 402 rises, when the liquid level reaches a set high level, an alarm signal is triggered, and the control unit 200 controls the water pump 407 to close, and at the same time controls the electric stop valve 408 to close, and water addition stops.

[0095] During the output process of hydrogen and oxygen gas, if the pipeline is blocked, resulting in poor gas output, the gas pressure in the circulating liquid storage tank 402 and the gas cooling and water filtering device 403 will continue to increase. The circulating liquid storage tank pressure sensor 402.14 is used to monitor the gas pressure change in the circulating liquid storage tank 402 in real time. When the gas pressure in the circulating liquid storage tank 402 reaches the alarm upper limit pressure value, a signal alarm is triggered, and the control unit 200 controls the intelligent controllable electrolytic power supply 300 to stop power supply in time, and the entire vehicle internal combustion engine energy-saving and emission reduction device 400 is turned off to stop generating gas; when the circulating liquid storage tank pressure sensor 402.14 fails or the control unit 200 fails, and the pressure cannot be protected and monitored, since a circulating liquid storage tank pressure relief cover 402.11 is provided on the top of the circulating liquid storage tank 402, when the gas pressure in the circulating liquid storage tank 402 reaches the alarm upper limit pressure value, the protective spring in the circulating liquid storage tank pressure relief cover 402.11 is compressed under the action of pressure, so that the pressure relief port is opened, and it automatically resets after the pressure is released.

[0096] Working principle of an automatic control system for an energy-saving device for an internal combustion engine of a vehicle:

[0097] The control unit first detects the vehicle start-stop state, and when the vehicle is powered on, performs parameter pre-detection on the vehicle and the hydrogen-oxygen-assisted fuel-saving and emission-reduction device for the vehicle internal combustion engine;

[0098] When the engine is in the starting state, the control unit enters the normal operation mode and judges the engine's operating conditions (idling, normal driving) based on the detection information of the vehicle's own sensors and external sensors;

[0099] When the vehicle starts to run normally, the control unit collects, analyzes, and calculates the data of each sensor in real time, and judges the vehicle's working conditions, driving environment, road, and traffic conditions in real time (the vehicle's working conditions include: driving states such as vehicle startup, acceleration, constant speed, deceleration, etc.; the driving environment includes: weather conditions, ambient temperature, air humidity, ambient wind force, atmospheric pressure, etc.; the road and traffic conditions include: flat, ramp, or rough road conditions, urban, suburban, or highway roads, traffic smooth or congested conditions, etc.);

[0100] Meanwhile, the control unit collects the voltage and current values of the intelligent controllable electrolysis power supply in real time. Through the collection and analysis of the above parameters, according to the strategy set by the program, it outputs according to the current values calibrated under different states such as the vehicle's working conditions, driving environment, road, and traffic conditions. When the electrolysis current value changes, the gas production of the water electrolysis cell also changes accordingly, so as to realize the control of the gas supply volume of the fuel-saving and emission-reduction device for vehicle internal combustion engines.

[0101] By collecting, analyzing, and calculating the data of each sensor in the fuel-saving and emission-reduction device for vehicle internal combustion engines in real time by the control unit, it judges the operation situation of the device in real time, identifies various alarm and fault states, and timely controls each actuator to perform corresponding processing actions to ensure the normal operation and fault alarm of the whole device.

[0102] Among them, the control unit can maintain a real-time communication connection with the background data server through the network, and record in real time the relevant information of the vehicle (such as vehicle speed, position, interval trajectory, etc.), various parameters in the fuel-saving and emission-reduction device for vehicle internal combustion engines (such as operation start-stop state, internal component execution action records, alarm and fault codes, etc.), device maintenance records, etc., and push the items to be processed to network terminals such as sales and after-sales service in a timely manner.

[0103] The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention. Any technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of the present invention's rights protection.
