Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen and oxygen generators, and more particularly to an integrated intelligent water electrolysis hydrogen and oxygen generator system station. Background Art

[0002] At present, small and medium-sized water electrolysis hydrogen production or water electrolysis hydrogen and oxygen mixed gas process equipment are supplied to the market in the form of single sets, and the gas production of a single set is mostly no more than 20000m 3 / h, when multiple sets are used for gas supply at the same time or the gas supply volume is greater than 20000m 3 / h or more, it is necessary to concentrate multiple small and medium-sized water electrolysis equipment in an independent space to meet the use of a large number of gas supply points or to meet the large gas demand. In order to facilitate the operation, operation, maintenance, safety and other management needs of the equipment, the water electrolysis hydrogen and oxygen generating device (or equipment) requires an independent workspace for easy management. For example, in steel enterprises, an area is generally selected in advance to build a hydrogen and oxygen generator workstation using brick-concrete or steel frame structure, and multiple sets of hydrogen and oxygen generators are placed in the station to achieve the purpose of centralized management. This kind of scheme for building hydrogen and oxygen generating stations is extremely common in the market. The requirements for steel mills are relatively stringent. It is necessary to meet multiple design specifications such as construction, water heating, ventilation, and industrial gas safety at the same time. A lot of money and manpower are invested in the construction of hydrogen and oxygen stations each time, which is not conducive to cost reduction. In addition, the conditions of steel mills vary, and they are greatly restricted by conditions such as site, cost, and design safety. Therefore, the application of hydrogen and oxygen generators is often hindered by such restrictions.

[0003] In addition, each hydrogen and oxygen generator inside the workstation is an integrated machine currently used, that is, each power system and each electrolyzer uses a set of integrated frame and generator shell. The problem with this solution is: low space utilization, and each device uses a separate frame and generator shell, which causes waste of materials and high cost.

[0004] Therefore, in order to solve the above-mentioned problems faced by steel mills when using water electrolysis hydrogen and oxygen generators, how to provide a simpler, more flexible, small-footprint, low-cost integrated intelligent water electrolysis hydrogen and oxygen generator system station is an urgent problem that technical personnel in this field need to solve. Summary of the invention

[0005] In view of this, the present invention provides an integrated intelligent water electrolysis hydrogen and oxygen generator system station which is simpler, more flexible, occupies a smaller area and has a lower cost.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] All-in-one intelligent water electrolysis hydrogen and oxygen generator system station, including:

[0008] A cabinet, wherein a plurality of side doors are provided on both sides of the cabinet, a camera is provided on the top wall of the cabinet, and a hydrogen and oxygen sensor is provided on an inner side wall of the cabinet;

[0009] A water electrolysis hydrogen-oxygen generator module, wherein the water electrolysis hydrogen-oxygen generator module is multiple and is arranged inside the cabinet along the length direction of the cabinet and is arranged corresponding to the corresponding side door positions respectively. Each of the water electrolysis hydrogen-oxygen generator modules is provided with a temperature sensor for detecting the temperature of the electrolytic cell, a pressure sensor for detecting the pressure of the output gas and a solenoid valve for closing the output gas. The temperature sensor is arranged on the electrolytic cell, and the pressure sensor and the solenoid valve are both arranged on the exhaust pipe on the electrolytic cell;

[0010] A water supply tank, the water supply tank is arranged at the top of the cabinet, and the water outlet of the water supply tank is connected to the plurality of electrolytic cells through pipelines, and the pipelines are provided with corresponding switch valves;

[0011] A power supply main management cabinet, which is arranged on one side of the cabinet body and is electrically connected to the electrolysis power supply boxes on the multiple water electrolysis hydrogen and oxygen generator modules;

[0012] A remote management platform is connected to the camera, the hydrogen and oxygen gas sensor, the temperature sensor, the pressure sensor, the solenoid valve, the switch valve, and the power supply main management cabinet by radio.

[0013] It can be known from the above technical scheme that compared with the prior art, the present invention discloses an integrated intelligent water electrolysis hydrogen and oxygen generator system station, which uses an integrated cabinet frame to build a whole hydrogen and oxygen generating room with a station as a unit, which not only saves the traditional brick-concrete and steel frame structure, but also saves the packaging cost of multiple single equipment, making it more convenient and flexible to use, easy to install, and small footprint, without excessive investment in building hydrogen and oxygen generating stations, reducing the initial investment cost. In addition, the remote management platform can also be used to observe the use of on-site equipment in real time through the camera, and monitor the on-site hydrogen and oxygen gas leakage, the output hydrogen and oxygen gas pressure and the temperature of the electrolyzer during operation. When a problem occurs, the remote management platform can remotely control the solenoid valve, the switch valve and the power supply main management cabinet to stop working, so that the system station stops producing gas, so as to improve the safety of the system station. Therefore, the system station adopts intelligent management, which can reduce on-site management of personnel, reduce the work intensity of personnel and improve the safety of personnel.

[0014] Furthermore, it also includes a water treatment device arranged in the cabinet, the water inlet of the water treatment device is connected to the external water source through a first water pipe, and the water outlet of the water treatment device is connected to the water inlet of the water supply and storage tank through a second water pipe.

[0015] The beneficial effect of adopting the above technical solution is that the water treatment equipment can convert the on-site water source into pure water or distilled water specially used for electrolysis conditions and store it in a water supply tank to provide water source for the equipment.

[0016] Furthermore, it also includes a plurality of racks arranged in the cabinet, the electrolytic cell is placed under the racks, and the electrolytic power supply box is placed on the top of the racks.

[0017] The beneficial effect of adopting the above technical solution is to make full use of space, reduce the space occupied by the water electrolysis hydrogen and oxygen generator module in the cabinet, and greatly reduce the overall system station footprint.

[0018] Furthermore, the plurality of racks are arranged in multiple rows, and longitudinal tracks arranged along the length direction of the cabinet are laid between two adjacent rows of racks on the inner bottom wall of the cabinet, and transverse tracks arranged along the width direction of the cabinet are laid below the racks on the inner bottom wall of the cabinet, and the electrolytic cell is placed on the transverse tracks.

[0019] Furthermore, a moving wheel is provided at the bottom end of the electrolytic cell, and the moving wheel is in rolling contact with the transverse track.

[0020] The beneficial effect of adopting the above technical solution is that by opening the side door, the electrolytic cell can be pushed out along the horizontal track, and the electrolytic power box can be moved along the longitudinal guide rail. After moving into place, it can be moved to the placement rack, which is convenient for maintenance and replacement of the electrolytic cell and the electrolytic power box.

[0021] Furthermore, a stop column for stopping the moving wheel is provided at a position of the transverse track away from the side door.

[0022] The beneficial effect of adopting the above technical solution is that when installing the electrolytic cell, the electrolytic cell is pushed along the transverse track until the moving wheel abuts against the stop column, thereby preventing the electrolytic cell from being pushed out of the transverse guide rail.

[0023] Furthermore, a cooling fan connected to the remote management platform radio is installed on the side door.

[0024] The beneficial effect of adopting the above technical solution is that a fixed air duct is formed in the box body to stabilize ventilation and heat dissipation by adopting the left-right configuration.

[0025] Furthermore, the exhaust pipe extends out of the cabinet and is connected to an external anti-backfire safety junction cabinet.

[0026] The beneficial effect of adopting the above technical solution is that it can effectively prevent flame flashback and cause danger.

[0027] Furthermore, a front door is provided on the front side of the cabinet.

[0028] The beneficial effect of adopting the above technical solution is that it facilitates the management of the equipment inside the cabinet.

[0029] Furthermore, the cabinet body is formed by welding sheet metal.

[0030] The beneficial effects of adopting the above technical solution are low cost, simple manufacturing, and the cabinet can be processed according to the actual required size or assembled by splicing several cabinets. BRIEF DESCRIPTION OF THE DRAWINGS
