Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen production, in particular to a novel environmentally friendly hydrogen production equipment. Background Art

[0002] As an important secondary energy source, hydrogen energy is crucial to my country's energy security, regional environmental pollution control, and global climate change response. The ammonia nitrogen in various wastewaters has poor biodegradability. If discharged directly, it will cause great harm to the ecological environment, seriously affecting and restricting people's lives and the healthy development of industry and agriculture.

[0003] In some industrial wastewater, ammonia nitrogen concentrations sometimes exceed 10,000 ppm. Some chemical plant wastewater has concentrations as high as 40,000 ppm. Furthermore, in wastewater from sources like landfill leachate and aquaculture wastewater, ammonia nitrogen concentrations often exceed 1,500 ppm, posing a significant environmental risk and hindering energy recycling. To address these issues, we have developed a new, environmentally friendly hydrogen production equipment. Utility Model Content

[0004] The utility model discloses a novel environmentally friendly hydrogen production equipment, which aims to solve the technical problem that the ammonia nitrogen concentration in wastewater in the fields of landfill leachate, aquaculture waste liquid, etc. often exceeds 1500ppm, which is highly harmful to the environment and is not conducive to the recycling of energy.

An inlet head is installed at one end of the delivery pipe close to the stripping tower, and a discharge head is installed at one end of the delivery pipe close to the electrochemical reaction tank.

[0007] In a preferred solution, switch valves are installed at equal intervals on the outside of the delivery pipe, and the switch valves are independently controlled, so that each section of the delivery pipe can be controlled individually.

[0008] In a preferred embodiment, the bottoms of the stripping tower, scrubber, regeneration tank and electrochemical reaction tank are all fixedly connected to a supporting base.

[0009] In a preferred solution, a drain pipe is fixedly connected to the bottom of the stripping tower.

[0010] In a preferred solution, the electrochemical reaction box is electrically connected to an external controller.

[0011] The new environmentally friendly hydrogen production equipment provided by the utility model has the following advantages:

[0012] Firstly, by installing hydrogen production equipment, wastewater can be purified, eliminating the ammonia nitrogen treatment system in the traditional sewage treatment process, which can reduce the sewage treatment cost by at least 20%; secondly, the ammonia removal rate index is stable, which can ensure that the sewage treatment meets the discharge standards and the ammonia nitrogen concentration of various types of wastewater after treatment is reduced to less than 1 mg / L; thirdly, clean new energy hydrogen with a purity of 99.99% is produced, which has certain additional benefits and achieves waste resource utilization.

[0013] Secondly, the supporting base can support the stripping tower, scrubber, regeneration box and electrochemical reaction box to play a protective role.

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0019] Reference Figure 1 - Figure 3A new type of environmentally friendly hydrogen production equipment includes a stripping tower 1, a scrubber 2 is provided on the outside of the stripping tower 1, a regeneration box 3 is provided on the outside of the scrubber 2, and an electrochemical reaction box 4 is provided on the outside of the regeneration box 3. The tops of the stripping tower 1, the scrubber 2, the regeneration box 3 and the electrochemical reaction box 4 are all connected with connecting pipes 5, and the connecting pipes 5 are connected with delivery pipes 6. The end of the delivery pipe 6 close to the stripping tower 1 is equipped with a feed head 8, and the end of the delivery pipe 6 close to the electrochemical reaction box 4 is equipped with a discharge head 9. On-off valves 7 are equidistantly installed on the outside of the delivery pipe 6. The on-off valves 7 are independently controlled, and each section of the delivery pipe 6 can be controlled separately. A drain pipe is fixedly connected to the bottom of the stripping tower 1.

[0020] In the above technical solution, considering that the concentration of ammonia nitrogen in wastewater from fields such as landfill leachate and aquaculture wastewater often exceeds 1500ppm, which poses a high risk to the environment and is not conducive to the recycling of energy, in order to solve such problems, the specific operations are as follows:

[0021] Reference Figure 1 - Figure 3 In a preferred embodiment, wastewater and air are injected into stripping tower 1, which is then pressurized and heated to 800-850°C. A catalyst decomposes ammonia into hydrogen and nitrogen. The chemical equation is: 2NH₃ → 3H₂ + N₂. In this process, hydrogen accounts for the main proportion (about 75%), and nitrogen is a by-product (about 25%). The treated wastewater is discharged through the drain pipe, and then the mixed gas is injected into the scrubber 2. The mixed gas reacts simultaneously in the scrubber 2 and the regeneration box 3, and then starts to enter the electrochemical reaction box 4, so that the mixed gas is separated from the hydrogen and nitrogen by the electrochemical reaction box 4. Through the set hydrogen production equipment, firstly, the wastewater can be purified, and the ammonia nitrogen treatment system part in the traditional sewage treatment process is omitted, which can reduce the sewage treatment cost by at least 20%; secondly, the ammonia removal rate index is stable, which can ensure that the sewage treatment meets the discharge standards and the ammonia nitrogen concentration of various types of wastewater after treatment is reduced to within 1 mg / L; thirdly, clean new energy hydrogen with a purity of 99.99% is produced, which has certain additional benefits and achieves waste resource utilization.

[0022] Reference Figure 1 - Figure 3 In a preferred embodiment, a support base 10 is fixedly connected to the bottom of the stripping tower 1, scrubber 2, regeneration tank 3, and electrochemical reaction tank 4. The electrochemical reaction tank 4 is electrically connected to an external controller. The support base 10 provides support and protection for the stripping tower 1, scrubber 2, regeneration tank 3, and electrochemical reaction tank 4. A controller allows operators to control the opening and closing of the electrochemical reaction tank 4, simplifying operation.

[0023] Working Principle: First, the required wastewater and air are injected into stripping tower 1. The interior of stripping tower 1 is then pressurized and heated to 800-850°C. A catalyst decomposes ammonia into hydrogen and nitrogen. The chemical equation is: 2NH3 → 3H2 + N2. Hydrogen accounts for the majority of this process (approximately 75%), with nitrogen as a byproduct (approximately 25%). The treated wastewater is discharged through a drain pipe. The mixed gas is then injected into scrubber 2, where it reacts simultaneously in scrubber 2 and regeneration tank 3. The mixture then enters electrochemical reactor 4, where it separates hydrogen from nitrogen. The clean hydrogen energy is then piped to a storage tank for storage. Hydrogen detection can be performed by observing no noticeable ammonia odor from the vent or an orange flame from the decomposition gas. Chemical instruments can also be used for detection.

The replacements described may be partial structures, devices, or method steps, or they may be complete technical solutions. Any equivalent replacements or modifications based on the technical solution and the concept of the present invention shall be covered by the scope of protection of the present invention.
