[0041] Reference Figures 1-6 An embodiment of a hydrogen oxygen removal device and method of the present application:

[0042] The method of removing oxygen from water using hydrogen mainly relies on the reducing ability of hydrogen. Hydrogen can react with oxygen in water to produce water, thereby achieving the purpose of removing oxygen. This method is commonly used in industrial applications, especially in situations where high-purity hydrogen is required;

[0043] The device comprises an oxygen remover 1 and a water tank 2 arranged below the oxygen remover 1; the oxygen remover 1 comprises a mounting shell 3, the upper part of the mounting shell 3 is provided with a spray head 4 and a gas outlet, and the middle part is provided with a filler 5; the filler 5 is provided with a uniform distribution device 6 between the filler 5 and the hydrogen adding hole; one side of the mounting shell 3 is provided with a steam adding hole, and the other side is provided with a hydrogen adding hole;

[0044] When the device is in use, the water to be deoxygenated is sprayed from the spray head 4, and the water is uniformly sprayed on the filler 5, then hydrogen is introduced into the oxygen remover 1 through the hydrogen adding hole, the hydrogen rises due to its density, and after being uniformly distributed by the uniform distribution device 6, it enters the filler 5, at this time the hydrogen will fully contact with the oxygen in the water, and an oxidation reaction will occur to produce water; in this way, the purpose of removing oxygen from water by hydrogen is achieved;

[0045] In order to increase the reaction speed of hydrogen and oxygen, a catalyst is added in the device, which is a gas catalyst participating in and accelerating the reaction of hydrogen and oxygen.

[0046] Since the oxidation reaction of hydrogen and oxygen occurs more efficiently at a higher temperature, the temperature of the oxidation reaction of hydrogen and oxygen, that is, the temperature of the internal space of the filler 5, needs to be increased. The device increases the internal temperature of the filler 5 by steam heating. High-temperature steam is added from the steam addition hole when hydrogen and oxygen react. The high-temperature steam uniformly enters the gaps in the filler 5 through the uniform distribution device 6. The heat carried by the steam heats the filler 5 to increase the temperature of the filler 5 and accelerate the oxidation reaction of hydrogen and oxygen.

[0047] The steam used in the device contains a small amount of oxygen, usually not more than 7 ppb, that is, 7 parts per billion. The oxygen in the hydrogen water is also reduced to 7 ppb. Therefore, compared with the electric heating method in the prior art, the steam can penetrate into all the pores of the filler 5, and the heating efficiency is very high.

[0048] At the same time, the reaction of hydrogen and oxygen generates water, which is an exothermic reaction. Combined with the pressure involved in the device, the steam will be overheated, which will cause the temperature of the filler 5 to be always high, but the temperature of the cylinder wall is relatively low, and the heat in the middle cannot be removed in time, which may cause the central part of the filler 5 to sinter and reduce the service life of the filler 5. The filler 5 is a high-activity palladium catalyst, and the temperature of the palladium catalyst increases as the reaction of oxygen and hydrogen to generate water proceeds.

[0049] To solve the above problems, the device is provided with a main heat dissipation column 7 at the center of the filler 5. The main heat dissipation column 7 is provided with a heat dissipation system 8. The heat dissipation system 8 includes a spiral channel 81 installed in the main heat dissipation column 7. The upper end of the spiral channel 81 is connected to an inlet pipe 82, and the lower end of the spiral channel 81 is connected to an outlet pipe 83. The cooling liquid outside can enter the spiral channel 81 in the main heat dissipation column 7 through the inlet pipe 82, take away the temperature of the main heat dissipation column 7 through the spiral channel 81, and finally output from the outlet pipe 83 to complete the heat dissipation of the main heat dissipation column 7. In this way, the problem of too high temperature at the center of the filler 5 can be prevented.

[0050] The upper end of the main heat dissipation column 7 is provided with a connecting column 9, and the connecting column 9 is connected with a secondary heat dissipation column 10. The secondary heat dissipation column 10 is circumferentially distributed around the main heat dissipation column 7, and the secondary heat dissipation column 10 is inserted into the filler 5.

[0051] In order to cope with the exothermic reaction of hydrogen and oxygen, the device is also provided with a secondary heat dissipation column 10, which is not arranged at the center of the filler 5, but at the position between the center of the filler 5 and the cylinder wall of the deaerator 1, and the number of the secondary heat dissipation column 10 is six, which is uniformly distributed around the main heat dissipation column 7, the purpose is to further improve the heat dissipation effect of the filler 5 and improve the service life of the filler 5.

[0052] The device is also provided with a connecting column 9 between the main heat dissipation column 7 and the secondary heat dissipation column 10, which is arranged for heat exchange between the main heat dissipation column 7 and the secondary heat dissipation column 10, so that the heat of the secondary heat dissipation column 10 can be transferred to the main heat dissipation column 7 through the connecting column 9; at the same time, the connecting column 9 is embedded in the filler 5, so that the connecting column 9 can also absorb part of the temperature of the filler 5, further increasing the heat dissipation efficiency.

[0053] The main heat dissipation column 7 is a trapezoidal circular cone, and the main heat dissipation column 7 is provided with a liquid inlet groove 11, which is uniformly distributed on the main heat dissipation column 7, and the main heat dissipation column 7 is provided with a liquid outlet 12, which penetrates the lower end surface of the main heat dissipation column 7, and the liquid outlet 12 is communicated with the liquid inlet groove 11.

[0054] The temperature of the main heat dissipation column 7 of the device is lower than the ambient temperature, at this time the main heat dissipation column 7 is equivalent to a condenser in a certain sense, and after the steam contacts the main heat dissipation column 7, it will directly form condensed water, which has very low oxygen content and does not need to be operated by hydrogen deoxidation, but if this part of water is not treated, it will occupy the space of the filler 5, thereby occupying the space of the water to be deoxidized, reducing the deoxidization efficiency; therefore, the device needs to prevent this part of water with very low oxygen content from entering the filler 5; the main heat dissipation column 7 is set to a trapezoidal circular cone, and then a circle of inclined liquid inlet grooves 11 is arranged on the trapezoidal circular cone, at this time the condensed water will slide down along the surface of the trapezoidal circular cone, and then enter the liquid inlet groove 11, then the condensed water enters the liquid outlet 12, and finally is directly output without entering the filler 5.

[0055] The uniform distribution device 6 comprises a mounting frame 61, and an inclined plate 62 is arranged in the mounting frame 61.

[0056] The function of the mounting frame 61 is to arrange the inclined plate 62, and the inclined plate 62 is provided with a gap for the steam to rise; when the steam rises, it will be guided by the inclined plate 62, and then pass through the gap between the inclined plates 62; in this way, the steam can be preliminarily uniformly distributed, so that the steam can more uniformly contact and heat the filler 5.

[0057] The inclined directions of the inclined plates 62 of the adjacent two uniform distribution devices 6 are opposite.

[0058] In this way, the two adjacent inclined panels 62 are oppositely inclined, when the steam enters the lower inclined panel 62, the flow direction is changed, and then enters the upper inclined panel 62, at this time, due to the change of the inclination direction of the inclined panel 62, the direction of the steam flow is changed; the direction of the steam flow is repeatedly changed through the upper inclined panel 62, so that the steam can uniformly enter the filler 5, and the filler 5 is uniformly heated by the steam.

[0059] The inclined panel 62 is installed on the mounting frame 61 through a rotating shaft, the rotating shaft is connected with the inclined panel 62, and a damper is arranged between the rotating shaft and the mounting frame 61.

[0060] The inclination direction of the inclined panel 62 in the device can be adjusted, and the reason for this arrangement is that the rising speed of the steam can be increased according to the inclination direction of the inclined panel 62, the faster the rising speed of the steam, the less the heat loss, and the higher the temperature of the filler 5 will be heated; when the inclined plate 62 is completely vertical, the steam rises vertically, the speed is the fastest, and the heat loss is the least; when the inclined plate 62 is horizontal, the gap between the inclined plates 62 will be blocked, and the steam cannot pass through; when the inclined plate 62 has a small gap, the steam needs to pass through the small gap, and the heat loss will be more.

[0061] The water tank 2 is provided with a catalyst pipe 13 near the bottom, a plurality of extension pipes 14 are installed on the catalyst pipe 13, and gas outlets 15 are arranged at the ends of the extension pipes 14; the extension pipes 14 are inclined downward from the connection end of the catalyst pipe 13 to the end where the gas outlets 15 are located.

[0062] The catalyst pipe 13 in the device provides a catalyst, the entire water tank 2 is filled with 70% water, the catalyst pipe 13 is immersed in water and arranged near the bottom of the water tank 2, a plurality of extension pipes 14 are arranged on the catalyst pipe 13, and the extension pipes 14 are inclined downward; when the catalytic gas enters the extension pipe 14, it can be output from the gas outlet of the extension pipe 14 into the water in the water tank 2, and then rises from the water into the upper deoxidizer 1, passes through the uniform distribution device in the deoxidizer 1, enters the filler, participates in and catalyzes the reaction of hydrogen and oxygen, accelerates the reaction process, and improves the oxygen removal efficiency.

[0063] Under the action of the catalyst, a small amount of oxygen in the hydrogen can react with the hydrogen to generate water, thereby achieving the purpose of oxygen removal. The catalyst in the device also passes through the uniform distribution device 6 during the rising process, uniformly enters the filler 5, and accelerates the exothermic reaction of hydrogen and oxygen.

[0064] Hydrogen oxygen removal method:

[0065] Step 1: Purify hydrogen;

[0066] Step 2: Purified hydrogen is introduced into the deaerator 1;

[0067] Step 3: The hydrogen introduced into the deaerator 1 rises through the distribution device 6 and is fully contacted with the water sprayed by the spray head 4 in the filler 5. The hydrogen reacts with the oxygen in the water to remove the oxygen.

[0068] Step 4: When the hydrogen is contacted with the water, a catalyst is supplied to the deaerator 1 to accelerate the reaction rate of the hydrogen and the oxygen.

[0069] Referring to Figure 6 In step 1, the hydrogen is purified. The raw material hydrogen (one at 0.8 MPa and normal temperature, and the other at 3 MPa and normal temperature) outside the factory is transported into the factory through a pipeline, impurities in the raw material gas are removed through a purification device, and the purified hydrogen is pressurized to 20 MPa by a compressor and then filled into a tube bundle vehicle or a steel cylinder.

[0070] The process of the purification device is as follows. The raw material gas is transported from the pipeline outside the boundary zone, first passes through the deoxidation process of MDP-D to completely remove the oxygen, and then enters the PSA process of MDP-P to purify the hydrogen to meet the requirements of fuel hydrogen. The product hydrogen obtained meets the standard requirements of GB / T37244-2018 “Fuel Hydrogen for Proton Exchange Membrane Fuel Cell Vehicles”.

[0071] The MDP-P process is used to separate H2 from CO, CH4, N2 and other impurity components, which is the main process. The MDP-D deoxidation process is used to catalytically react the oxygen in the raw material gas with hydrogen to generate water, thereby completing the removal of oxygen.

[0072] The PSA process of MDP-P adopts a 6-tower design. In the case of gas source 1, 5 adsorption towers are used, 1 tower is adsorbed at the same time, 2 times of pressure equalization is performed, and the adsorbent is subjected to primary flushing. In the case of gas source 2, 6 adsorption towers are used, 1 tower is adsorbed at the same time, 3 times of pressure equalization is performed, and the adsorbent is subjected to primary flushing and regeneration.

[0073] The adsorption towers of the PSA process work alternately. In one cycle, each adsorption tower must go through the following steps: adsorption, pressure equalization and pressure reduction, forward discharge, reverse discharge, flushing, pressure equalization and pressure increase, and final pressure charging.

[0074] (1) Adsorption

[0075] The hydrogen-rich gas is introduced into the adsorption tower of the MDP-P process. Under the predetermined adsorption pressure, the impurities in the hydrogen-rich gas are adsorbed by the special adsorbent, and H2 flows out from the top of the adsorption tower as product gas. When the leading edge of the mass transfer zone in the adsorption tower reaches the predetermined position of the adsorption tower, the raw material gas inlet valve and the adsorption tail gas outlet valve of the adsorption tower are closed, and the adsorption tower stops the adsorption step and starts the regeneration process.

[0076] (2) Pressure equalization and pressure reduction

[0077] After the adsorption step is completed, the adsorption column is connected in turn with the adsorption column at low pressure, and the useful components in the dead space of the adsorption column are recovered.

[0078] (3) Forward release

[0079] After the equalization and pressure reduction step is completed, the adsorption column is subjected to multiple forward release processes to the forward release gas buffer tank, reducing the pressure of the adsorption column, and the forward release gas is used as the regeneration flushing gas for other adsorption columns.

[0080] (4) Reverse release

[0081] After the forward release step is completed, the adsorption front of impurities is close to the outlet of the adsorption column, and reverse release is started to reduce the pressure of the adsorption column to near atmospheric pressure. The reverse release process can also partially desorb the impurities adsorbed by the adsorbent.

[0082] (5) Flushing

[0083] After the reverse release is completed, in order to effectively regenerate the adsorbent, the forward release gas in the forward release gas buffer tank is used to flush the adsorption column in the reverse direction, so that the adsorbent is completely desorbed.

[0084] (6) Equalization and pressure increase

[0085] After the flushing step is completed, higher pressure gas from other adsorption columns is used to sequentially equalize and increase the pressure of the adsorption column, gradually increasing the pressure of the adsorption column.

[0086] (7) Final pressure increase

[0087] The adsorption column that has gone through the above equalization and pressure increase steps has not yet reached the predetermined adsorption pressure. In order to smoothly switch to the next adsorption, the adsorption column is finally pressurized with product H2, and the pressure of the adsorption column is increased to the predetermined adsorption pressure.

[0088] At this point, the adsorption column has completed a complete adsorption-regeneration cycle process and is ready for the next cycle process.

[0089] Each adsorption column alternately performs the above steps, and cooperates with each other to operate smoothly, so that the entire device runs smoothly and the required H2 product gas is obtained.

[0090] In this hydrogen purification process, after the raw gas enters, it passes through three modules of MDP-D purification, MDP-P crude hydrogen purification, and MDP-T fine impurity removal, and finally obtains the project product gas.

[0091] Using a special adsorbent, CO and H2S toxic impurities in hydrogen are deeply and accurately removed, realizing high selectivity separation of hydrogen and impurities; the adsorbent has the advantages of high adsorption capacity, high selectivity, high stability, environmental friendliness, low preparation cost, etc.

[0092] Optimization process, through the continuous operation process, the development of efficient, low, low energy consumption of new hydrogen purification process. Solve the PSA technology output hydrogen impurity content fluctuation problem, can be stable output in line with the fuel hydrogen standard of hydrogen. The process is advanced at home and abroad.

[0093] The purification process has organic integration purification module, optimization integrated modular design, developed a small footprint, convenient transportation, low energy consumption, high yield and stable quality of fuel hydrogen purification demonstration device. The fuel hydrogen purification system device is advanced at home and abroad.

[0094] Then the purified hydrogen enters the oxygen remover 1, and the oxygen remover 1 is arranged above the water tank 2; The upper end of the oxygen remover is provided with three pipes, the middle one is a spray water pipe, one side is provided with a condensate water pipe, and the other is an exhaust pipe. Non-condensable gas is discharged through the exhaust pipe again, and a small amount of steam sprayed water mist falls on the heating filler 5 below, also known as the first stage filler 5; A plurality of uniform distribution devices 6 are arranged below the filler 5, which are called air separation uniform distribution devices 6, and sometimes also called degassing uniform distribution devices 6, secondary uniform distribution devices 6; The oxygen remover 1 is provided with a maintenance door on one side, which can be used for maintenance and replacement of the filler 5 and the uniform distribution device 6; Oxygen is reduced to 7 parts per billion; The lower end of the uniform distribution device 6 is provided with a space, when the steam enters the space of the uniform distribution device 6 from one side of the oxygen remover 1, it will first enter the space at the lower end of the uniform distribution device 6, then the steam rises into the uniform distribution device 6, and after being uniformly distributed by the uniform distribution device 6, it contacts the filler 5.
