Description

Technical Field

[0001] This application relates to the field of environmental protection equipment technology, specifically an energy-saving ammonia collection and treatment device. Background Technology

[0002] With the acceleration of industrialization, ammonia emissions have been increasing year by year, especially in the fields of chemical industry, agriculture and aquaculture. As a common harmful gas, ammonia poses a serious threat to the environment and human health. At present, ammonia treatment technologies mainly include physical adsorption, chemical absorption and biodegradation.

[0003] However, existing technologies have revealed that existing ammonia treatment devices suffer from low processing efficiency with physical adsorption methods and high energy consumption with chemical absorption methods. This makes it difficult to balance processing efficiency and energy saving, thus failing to meet the needs of ammonia treatment. Therefore, there is an urgent need for an ammonia collection and treatment device that can achieve both high efficiency and energy saving. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an energy-saving ammonia collection and treatment device, which has the advantages of significantly improving ammonia treatment efficiency while reducing energy consumption, thus solving the problem that it is difficult to balance treatment efficiency and energy saving when using existing devices.

[0005] To achieve the above objectives, this application provides the following technical solution: an energy-saving ammonia collection and treatment device, comprising a gas collection hood, a gas guide pipe fixedly installed on the right side of the gas collection hood, a fan fixedly installed at the right end of the gas guide pipe, a connecting pipe one fixedly installed at the output end of the fan, a multi-stage filter fixedly installed at the right end of the connecting pipe one, a connecting pipe two fixedly installed at the output end of the multi-stage filter, an energy-saving reactor fixedly connected at the right end of the connecting pipe two, a connecting pipe fixedly connected to the upper surface of the energy-saving reactor, a purification module fixedly installed at the right end of the connecting pipe, an exhaust pipe fixedly connected to the output end of the purification module, a molecular sieve layer fixedly installed on the inner wall of the multi-stage filter, an activated carbon layer fixedly installed on the inner wall of the multi-stage filter, and a high-efficiency catalyst disposed inside the energy-saving reactor.

[0006] To improve ammonia treatment efficiency and reduce energy consumption, the above scheme involves installing a gas guide pipe on the right side of the gas collection hood. A fan allows ammonia to enter a multi-stage filter. In the multi-stage filter, the ammonia undergoes initial adsorption through the molecular sieve and activated carbon layers, removing most of the ammonia. The remaining ammonia enters the energy-saving reactor through connecting pipe two. Inside the energy-saving reactor, it decomposes into nitrogen and water under the action of a highly efficient catalyst. Finally, the treated gas is transmitted to the purification module through connecting pipes. The purification module further removes residual pollutants, ensuring emissions meet standards. This device, through the synergistic effect of the multi-stage filter and the energy-saving reactor, significantly improves ammonia treatment efficiency while reducing energy consumption.

[0007] Furthermore, a sealing cover is fixedly installed on the upper surface of the multi-stage filter, and the sealing cover is fixed to the multi-stage filter by bolts.

[0008] The above method involves installing the sealing cover on the upper surface of the multi-stage filter with bolts, which facilitates sealing of the openings of the multi-stage filter. The use of multiple bolts for fixing ensures the airtightness of the connection.

[0009] Furthermore, the molecular sieve layer is made of 5A molecular sieve, and the activated carbon layer is made of coconut shell activated carbon.

[0010] The above scheme uses 5A molecular sieves for the molecular sieve layer. 5A molecular sieves can adsorb any molecule with a diameter smaller than its pore size, and have the characteristics of high selective adsorption and fast adsorption speed, which can improve adsorption efficiency. Coconut shell activated carbon is used for the activated carbon layer. Coconut shell activated carbon has a well-developed pore structure and a huge specific surface area, which enables it to adsorb a large number of ammonia molecules, thereby achieving efficient ammonia removal. This high adsorption capacity ensures the effectiveness of the multi-stage filter in the initial ammonia adsorption stage.

[0011] Furthermore, the highly efficient catalyst is a platinum-based catalyst.

[0012] The above scheme employs a platinum-based catalyst, which has high catalytic activity and can achieve the highest reaction rate required by experimental conditions at low temperatures, thereby improving the reaction rate. It also has excellent oxidation and corrosion resistance, and due to its stability and high efficiency, it has a very long service life.

[0013] Furthermore, a support frame is fixedly connected to the outer surface of the energy-saving reactor, and a drain pipe is fixedly connected to the bottom surface of the energy-saving reactor.

[0014] With the above scheme, the support frame is installed on the outer surface of the energy-saving reactor, which can support the energy-saving reactor. The drain pipe is set on the bottom surface of the energy-saving reactor, which facilitates the discharge of water separated in the energy-saving reactor.

[0015] Furthermore, a gas composition sensor is fixedly installed on the inner wall of the exhaust pipe, a support frame is fixedly connected to the bottom surface of the purification module, and an installation frame is slidably connected to the inner wall of the purification module.

[0016] The above solution involves installing a gas composition sensor on the inner wall of the exhaust pipe. This sensor can detect the composition of the exhaust gas, determine whether harmful substances have been effectively removed, and identify any other harmful gases produced. This ensures that the exhaust gas meets environmental standards. The second support frame is fixed to the bottom of the purification module to provide support. The mounting frame is placed on the inner wall of the purification module and is designed as a sliding connection to limit its movement.

[0017] Furthermore, an activated carbon plate is fixedly installed on the inner wall of the mounting frame, a sealing ring is provided on the outer surface of the mounting frame, and a limiting shell is provided on the top of the mounting frame.

[0018] The above method involves installing activated carbon plates on the inner wall of the mounting frame. The activated carbon plates are made of fruit shell activated carbon, which is environmentally friendly, has an excellent pore structure, a large specific surface area, and strong adsorption capacity. At the same time, the pores are evenly distributed, which can effectively remove organic matter, grease, and some gaseous impurities from nitrogen. The sealing ring is placed on the outer surface of the mounting frame, and the limiting shell is placed above the mounting frame. By setting the sealing ring between the mounting frame and the limiting shell, the sealing of the mounting frame after installation can be guaranteed, preventing nitrogen leakage.

[0019] Furthermore, two fixing bolts are installed on the inner wall of the limiting shell, and each fixing bolt is installed on the inner wall of the purification module and the mounting frame.

[0020] The above method involves installing fixing bolts on the inner wall of the limiting shell and connecting the fixing bolts to the purification module and the mounting frame, so that the mounting frame and the limiting shell can be fixed. After removing the limiting shell, the mounting frame and the activated carbon plate can be removed and replaced.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This energy-saving ammonia collection and treatment device incorporates multi-stage filters and an energy-saving reactor. A gas collection hood covers the ammonia source, and the ammonia gas enters the multi-stage filters via a gas guide pipe, fan, and connecting pipe one. In the multi-stage filters, preliminary adsorption occurs through molecular sieve and activated carbon layers, removing most of the ammonia. The remaining ammonia gas enters the energy-saving reactor through connecting pipe two, where it is decomposed into nitrogen and water by a highly efficient catalyst. Finally, the treated gas is transmitted to a purification module via connecting pipe. The purification module further removes residual pollutants, ensuring emissions meet standards. This device significantly improves ammonia treatment efficiency while reducing energy consumption through the synergistic effect of the multi-stage filters and the energy-saving reactor. A gas composition sensor installed on the inner wall of the exhaust pipe allows for real-time gas monitoring, ensuring that emissions comply with environmental standards. Attached Figure Description

[0039] This embodiment of an energy-saving ammonia collection and treatment device includes a multi-stage filter 5, an energy-saving reactor 7, and other components. A gas collection hood 1 covers the ammonia source, and the ammonia enters the multi-stage filter 5 through a gas guide pipe 2, a fan 3, and a connecting pipe 4. In the multi-stage filter 5, the ammonia undergoes preliminary adsorption through a molecular sieve layer 12 and an activated carbon layer 13, removing most of the ammonia. The remaining ammonia enters the energy-saving reactor 7 through a connecting pipe 6, where it is decomposed into nitrogen and water by a high-efficiency catalyst 14. Finally, the treated gas is transmitted to a purification module 9 through a connecting pipe 8. The purification module 9 further removes residual pollutants, ensuring emissions meet standards. This device significantly improves ammonia treatment efficiency and reduces energy consumption through the synergistic effect of the multi-stage filter 5 and the energy-saving reactor 7. A gas composition sensor 17 installed on the inner wall of the exhaust pipe 10 allows for real-time gas detection, ensuring that the emitted gas meets environmental standards.

[0040] It should be noted that fan 3 is a corrosion-resistant centrifugal fan made of corrosion-resistant materials. It can handle corrosive gases and has high efficiency and low noise level, making it suitable for use in ammonia collection and treatment equipment.

[0041] The working principle of the above embodiments is as follows:

[0042] First, the gas collection hood 1 is covered over the ammonia source to ensure good sealing. Then, the ammonia is smoothly introduced into the multi-stage filter 5 through the gas guide pipe 2 and the fan 3. In the multi-stage filter 5, the ammonia is initially adsorbed through the molecular sieve layer 12 and the activated carbon layer 13, removing most of the ammonia. The remaining ammonia enters the energy-saving reactor 7 through the connecting pipe 2 6. Inside the energy-saving reactor 7, it is decomposed into nitrogen and water under the action of the high-efficiency catalyst 14. Finally, the treated gas is transmitted to the purification module 9 through the connecting pipe 8. The activated carbon plate 20 in the purification module 9 can further remove residual pollutants. Finally, it is discharged through the exhaust pipe 10. During the discharge process, the gas composition sensor 17 can detect the gas in real time to ensure that the emitted gas meets environmental protection standards. When the activated carbon plate 20 needs to be replaced, the fixing bolts 23 are removed so that the limiting shell 22 can be removed, and then the mounting frame 19 is removed so that the activated carbon plate 20 can be replaced.
