Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of fertilizer production, and specifically to an environmental protection treatment mechanism for an intelligent fertilizer production system. Background Art
[0002] In the process of modern agricultural development, fertilizers, as a key factor in ensuring crop growth and yield, have seen continuous improvement in their production scale and intelligent level. The intelligent fertilizer production system, with the help of advanced automatic control, sensor technology, and data analysis means, has significantly improved production efficiency, product quality stability, and consistency. However, the environmental pollution problems generated during the fertilizer production process have always been the key factors restricting the sustainable development of this industry.
[0003] With the improvement of environmental protection awareness and the gradual improvement of environmental protection regulations, some enterprises have begun to introduce single dust removal equipment, such as bag filters. Bag filters use the filtration principle and can effectively intercept dust particles with larger particle sizes. However, the dust particle size distribution during fertilizer production is wide. In addition to dust with larger particle sizes, there are also a large number of dust particles with tiny particle sizes. These tiny dust particles are easy to penetrate the filter layer of the bag filter, resulting in the still excessive dust content in the discharged waste gas. Moreover, when the bag filter processes waste gas with high temperature and high humidity, problems such as bag blockage and bag sticking are likely to occur, affecting its normal operation and service life.
[0004] In terms of waste gas treatment, traditional treatment methods mainly involve simply washing the waste gas through an absorption tower. This method can only remove some water-soluble harmful substances in the waste gas, and the treatment effect on some insoluble harmful substances, such as volatile organic compounds (VOCs), nitrogen oxides, etc., is not good. Moreover, a large amount of wastewater will be generated during the water washing process. If this wastewater is directly discharged without effective treatment, it will cause serious pollution to the water environment. Summary of the Invention

[0006] To achieve the above purpose, the present invention provides the following technical solution: An environmental protection treatment mechanism for an intelligent fertilizer production system, including a bag filter. The inlet of the bag filter is connected to the waste gas discharge port of the fertilizer production equipment. The right side of the bag filter is connected to a cyclone separator through a first transfer pump. The right side of the cyclone separator is connected to a gravity sedimentation treatment tank in cooperation with a waste gas discharge pipe through a second transfer pump.

The right side of the top of the spray water washing tank communicates with a discharge pipe, and a second regulating valve is movably installed on the top of the discharge pipe.
[0007] As a preferred solution, the lower end of the exhaust gas discharge pipe is additionally communicated with a separation grid, the bottom of the separation grid is communicated with the inside of the gravity sedimentation treatment tank, and the seal fixing components are distributed on the front and back sides of the separation grid.
[0008] As a preferred solution, the seal fixing component includes a seal baffle, the seal baffle is in sealed contact with the end of the separation grid, both sides of the outside of the seal baffle are fixedly installed with abutting springs, the outer ends of the abutting springs are fixedly installed with fixing plates, and the bottom of the fixing plate is connected to the top of the gravity sedimentation treatment tank.
[0009] As a preferred solution, side baffles are fitted and installed on both sides of the separation grid, a bent baffle is installed inside the side baffle and at the end of the seal baffle, and one end of the bent baffle is slidably fitted with the surface of the side baffle.
[0010] As a preferred solution, a sealing plug is sleeved outside the connection part of the exhaust gas discharge pipe and the separation grid, and the connection part between the bottom of the sealing plug and the top of the separation grid is in sealed contact.
[0011] As a preferred solution, an atomizing pipe is fixedly installed above the back surface of the inner cavity of the gravity sedimentation treatment tank, a water pipe is communicated with the back surface of the atomizing pipe, and the rear end of the water pipe penetrates through the back surface of the gravity sedimentation treatment tank and is connected with a flange.
[0012] As a preferred solution, a slag discharge pipe is communicated with the right side of the bottom of the front surface of the gravity sedimentation treatment tank, and a first regulating valve is movably installed at the top of the slag discharge pipe.
[0013] As a preferred solution, a ventilation pipe is communicated with the top of the cyclone dust collector, a shielding disc is installed above the ventilation pipe, and a sealing block is clamped inside the upper end of the ventilation pipe.
[0014] As a preferred solution, the inner wall of the gravity sedimentation treatment tank is coated with a ceramic coating, the outer surface of the ceramic coating is coated with a wear-resistant rubber coating, and the outer surface of the wear-resistant rubber coating is coated with a catalytic coating.
[0015] As a preferred solution, it further includes an environmental protection treatment step, and the treatment steps are as follows: Step 1: The waste gas generated by the fertilizer production equipment first enters the bag filter. An alkaline chemical treatment agent is added inside, which can react with acidic gases (such as sulfur dioxide, nitrogen oxides, etc.) in the waste gas to neutralize them and convert them into stable substances such as salts. At the same time, it can adsorb some dust particles or harmful pollutants in the waste gas, changing the properties of the dust particles and making them more easily captured by the filter bags. Through the internal bag filtration of the bag filter, larger particulate dust and impurities in the waste gas can be intercepted. When the waste gas passes through the filter bags, the dust is retained on the surface of the filter bags, and the clean gas is discharged through the filter bags; Step 2: The waste gas treated by the bag filter is transported to the cyclone separator by the first transfer pump. The cyclone separator uses the action of centrifugal force to make the waste gas rotate inside the equipment. During the rotation process, the particles in the waste gas, due to their larger mass, are thrown towards the wall of the separator under the action of centrifugal force and then fall along the wall to the bottom of the separator, thus achieving the separation of particles and gas; Step 3: The waste gas coming out of the cyclone separator enters the gravity sedimentation treatment tank through the second transfer pump and the waste gas discharge pipe. Before entering the gravity sedimentation treatment tank, part of the waste gas will pass through the separation grid, which can further intercept and separate the particles in the waste gas. A ceramic coating and a wear-resistant rubber coating are added inside the gravity sedimentation treatment tank to cooperate in the dust removal work. The ceramic coating can effectively resist the erosion and wear of the particle-containing waste gas on the wall of the tank body, and the addition of the wear-resistant rubber coating provides additional protection and dust removal assistance functions for the tank body. The catalytic coating can accelerate the chemical reactions of some harmful components in the waste gas, prompting them to be converted into harmless or less harmful substances. After entering the gravity sedimentation treatment tank, the particles in the waste gas gradually settle to the bottom of the tank under the action of gravity. The atomizing pipe above the back of the inner cavity of the gravity sedimentation treatment tank will spray water mist into the tank. The water mist combines with the particles in the waste gas, increasing the mass of the particles and thus accelerating the sedimentation speed of the particles and improving the effect of gravity sedimentation; Step 4: The waste gas treated by gravity sedimentation enters the spray washing tank from the right side of the gravity sedimentation treatment tank. A spray device is arranged in the spray washing tank, which sprays a large amount of water into the waste gas. The water comes into full contact with the waste gas, further absorbing the harmful gases and fine particles in the waste gas. Through spray washing, most of the water-soluble harmful gases and the remaining particles in the waste gas can be removed, making the waste gas more thoroughly purified; Step 5: The waste gas treated by spray washing is discharged through the discharge pipe. The second regulating valve at the top of the discharge pipe can control the discharge speed and flow rate of the waste gas. After the above series of treatment steps, pollutants such as dust and harmful gases in the waste gas are effectively removed and discharged into the atmosphere after reaching the environmental protection discharge standards.
[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the multi-stage treatment of the bag filter, cyclone dust collector, gravity sedimentation treatment tank and spray washing tank, the present invention can effectively remove dust and pollutants of different particle sizes, improve the efficiency and effect of waste gas treatment. The sealing baffles are distributed on both sides of the separation grid, which can increase the sealing performance of the connection and can also reinforce its installation, ensuring the connection sealing between each treatment link, preventing waste gas leakage, improving the treatment efficiency, and the gravity sedimentation treatment tank is provided with a slag discharge pipe and a regulating valve, which is convenient for regularly cleaning the sedimented waste residue.
[0017] 2. By fitting and installing the side baffles on both sides of the separation grid, the present invention can effectively prevent waste gas from leaking from the side of the separation grid. The existence of the side baffles ensures that the waste gas can only enter the gravity sedimentation treatment tank through the predetermined channel, that is, the bottom of the separation grid, improving the sealing performance and effectiveness of waste gas treatment. The bent baffle is installed inside the side baffle and at the end of the sealing baffle, and one end of it is slidably fitted with the surface of the side baffle, and this design further enhances the sealing effect at the end of the separation grid.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0021] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments. Embodiment 1:
[0022] Please refer to Figure 1 As shown, the present invention provides an environmental protection treatment mechanism for a fertilizer intelligent production system, including a bag filter 1. The inlet of the bag filter 1 is connected to the exhaust gas discharge port of the fertilizer production equipment. The right side of the bag filter 1 is connected to a cyclone dust collector 2 through a first transfer pump 16. The right side of the cyclone dust collector 2 is connected to a gravity sedimentation treatment tank 3 through a second transfer pump 17 in cooperation with an exhaust gas discharge pipe 5. A sealing and fixing assembly 9 is installed on the top of the gravity sedimentation treatment tank 3. The right side of the gravity sedimentation treatment tank 3 communicates with a spray washing tank 4. The right side of the top of the spray washing tank 4 communicates with a discharge pipe 14. A second regulating valve 15 is movably installed on the top of the discharge pipe 14. Embodiment 2:
[0023] On the basis of Embodiment 1, as shown in the present invention Figure 5 As shown, the lower end of the exhaust gas discharge pipe 5 is additionally communicated with a separation grid 7. The bottom of the separation grid 7 is communicated with the inside of the gravity sedimentation treatment tank 3. The sealing and fixing assembly 9 is distributed on the front and back sides of the separation grid 7. The sealing and fixing assembly 9 includes a sealing baffle 901. The sealing baffle 901 is in sealing contact with the end of the separation grid 7. Both sides of the outside of the sealing baffle 901 are fixedly installed with abutting springs 903. The outer ends of the abutting springs 903 are fixedly installed with fixing plates 10. The bottom of the fixing plates 10 is connected to the top of the gravity sedimentation treatment tank 3.
[0024] Adopt as Figure 1In the technical solution shown, the sealing baffle 901 is in close sealing contact with the end of the separation grid 7, which can effectively prevent waste gas from leaking from the connection part between the separation grid 7 and the gravity sedimentation treatment tank 3. Through this sealing design, it can ensure that the waste gas flows along the predetermined path throughout the treatment process, improving the treatment efficiency. The good sealing performance helps to maintain the stable pressure and air flow distribution in the gravity sedimentation treatment tank 3. The setting of the pressing spring 903 makes the sealing baffle 901 have a certain elasticity. During the operation of the fertilizer intelligent production system, the equipment may vibrate, or due to factors such as temperature and pressure changes, the components may have small displacements. The pressing spring 903 can buffer these vibrations and displacements, ensuring that the sealing baffle 901 always maintains good sealing contact with the separation grid 7 and avoiding damage to the sealing performance due to the normal operation changes of the equipment.
[0025] Secondly, in the technical solution, side baffles 8 are fitted and installed on both sides of the separation grid 7. A bent baffle 902 is installed inside the side baffle 8 and at the end of the sealing baffle 901. One end of the bent baffle 902 is in sliding fit with the surface of the side baffle 8; an external sealing plug 6 is sleeved on the outside of the connection part between the waste gas discharge pipe 5 and the separation grid 7, and the bottom of the sealing plug 6 is in sealing contact with the connection part at the top of the separation grid 7.
[0026] It adopts the technical solution as Figure 1 shown. The side baffles 8 are fitted and installed on both sides of the separation grid 7, which can effectively block the leakage of waste gas from the sides of the separation grid 7. The presence of the side baffles 8 ensures that the waste gas can only enter the gravity sedimentation treatment tank 3 through the predetermined channel, that is, the bottom of the separation grid 7, improving the sealing performance and effectiveness of the waste gas treatment. The bent baffle 902 is installed inside the side baffle 8 and at the end of the sealing baffle 901, and one end of it is in sliding fit with the surface of the side baffle 8. This design further enhances the sealing effect at the end of the separation grid 7.
[0027] The addition of the wear-resistant rubber coating 19 provides additional protection and dust removal auxiliary functions for the box body. The rubber material has good flexibility and elasticity, which can buffer the impact of dust particles on the box wall surface, reduce wear. At the same time, the special structure and properties of its surface make it difficult for dust to adhere, further improving the efficiency of gravity sedimentation. The catalytic coating 20 can accelerate the chemical reaction of some harmful components in the waste gas, prompting them to be converted into harmless or less harmful substances, further improving the purification effect of the waste gas. Embodiment 3:
[0028] The present invention is as Figures 1-6As shown in the figure, an atomizing pipe 11 is fixedly installed above the back surface of the inner cavity of the gravity sedimentation treatment tank 3. A water pipe is connected to the back surface of the atomizing pipe 11, and the rear end of the water pipe penetrates through the back surface of the gravity sedimentation treatment tank 3 and is connected with a flange; a slag discharge pipe 12 is communicated with the right side of the bottom of the front surface of the gravity sedimentation treatment tank 3, and a first regulating valve 13 is movably installed on the top of the slag discharge pipe 12; a ventilation pipe is communicated with the top of the cyclone dust collector 2, and a shielding disc is installed above the ventilation pipe. In addition, a sealing block is clamped inside the upper end of the ventilation pipe; the inner wall of the gravity sedimentation treatment tank 3 is coated with a ceramic coating 18, the outer surface of the ceramic coating 18 is coated with a wear-resistant rubber coating 19, and the outer surface of the wear-resistant rubber coating 19 is coated with a catalytic coating 20.
[0029] With the above technical solution, the atomizing pipe 11 is installed above the back surface of the inner cavity of the gravity sedimentation treatment tank 3, is communicated through a water pipe and can spray water to form an atomizing effect. When the waste gas enters the gravity sedimentation treatment tank 3, the atomized water droplets can combine with the dust particles in the waste gas. After the dust particles adsorb the water droplets, their mass increases and they are more likely to settle under the action of gravity, thereby significantly improving the efficiency of gravity sedimentation treatment and effectively removing the dust in the waste gas.
[0030] Secondly, a chemical treatment agent is added inside the bag filter 1. The added chemical treatment agent will undergo a chemical reaction or adsorption with certain components in the waste gas. For example, if an alkaline chemical treatment agent is added, it can undergo a neutralization reaction with acidic gases such as sulfur dioxide and nitrogen oxides in the waste gas and convert them into stable substances such as salts. At the same time, some chemical treatment agents have adsorption properties and can adsorb some dust particles or harmful pollutants in the waste gas, changing the properties of the dust particles and making them more easily captured by the filter bag. In some cases, the added chemical treatment agent may make the dust particles carry a certain charge. When the charged dust particles approach the filter bag, they will be affected by the electrostatic attraction force on the surface of the filter bag and thus adhere more firmly to the filter bag, improving the dust removal efficiency. In addition, the filter bag itself may also generate static electricity through friction and other means, enhancing the adsorption ability of dust.
[0031] The environmental protection treatment mechanism of the intelligent fertilizer production system further includes an environmental protection treatment step, and the treatment steps are as follows: The first step: The waste gas generated by the fertilizer production equipment first enters the bag filter 1. An alkaline chemical treatment agent is added inside it, which can undergo a neutralization reaction with acidic gases (such as sulfur dioxide, nitrogen oxides, etc.) in the waste gas and convert them into stable substances such as salts. At the same time, it can adsorb some dust particles or harmful pollutants in the waste gas, changing the properties of the dust particles and making them more easily captured by the filter bag. The bag filter 1 can intercept larger particle dust and impurities in the waste gas through the internal bag filtration. When the waste gas passes through the filter bag, the dust is intercepted on the surface of the filter bag, and the clean gas is discharged through the filter bag; Step 2: The waste gas treated by the bag filter 1 is transported to the cyclone separator 2 by the first transfer pump 16. The cyclone separator 2 utilizes the centrifugal force to make the waste gas rotate within the device. During the rotation, the particles in the waste gas, due to their larger mass, are thrown towards the wall under the action of the centrifugal force and then fall along the wall to the bottom of the dust collector, thus achieving the separation of particles and gas. Step 3: The waste gas coming out of the cyclone separator 2 enters the gravity sedimentation treatment tank 3 through the second transfer pump 17 and the waste gas discharge pipe 5. Before entering the gravity sedimentation treatment tank 3, part of the waste gas will pass through the separation grid 7. The separation grid 7 can further intercept and separate the particles in the waste gas. A ceramic coating 18 and a wear-resistant rubber coating 19 are added inside the gravity sedimentation treatment tank 3 to cooperate in the dust removal work. The ceramic coating 18 can effectively resist the erosion and wear of the particle in the dust-containing waste gas on the wall surface of the tank body. The addition of the wear-resistant rubber coating 19 provides additional protection and dust removal assistance functions for the tank body. The catalytic coating 20 can accelerate the chemical reaction of some harmful components in the waste gas, prompting them to be converted into harmless or less harmful substances. After entering the gravity sedimentation treatment tank 3, the particles in the waste gas gradually settle to the bottom of the tank under the action of gravity. The atomizing pipe 11 above the back of the inner cavity of the gravity sedimentation treatment tank 3 will spray water mist into the tank. The water mist combines with the particles in the waste gas, increasing the mass of the particles, thereby accelerating the sedimentation speed of the particles and improving the effect of gravity sedimentation. Step 4: The waste gas after gravity sedimentation treatment enters the spray washing tank 4 from the right side of the gravity sedimentation treatment tank 3. A spray device is provided in the spray washing tank 4, which sprays a large amount of water into the waste gas. The water comes into full contact with the waste gas, further absorbing the harmful gases and fine particles in the waste gas. Through spray washing, most of the water-soluble harmful gases and the remaining particles in the waste gas can be removed, making the waste gas more thoroughly purified. Step 5: The waste gas after spray washing treatment is discharged through the discharge pipe 14. The second regulating valve 15 at the top of the discharge pipe 14 can control the discharge speed and flow rate of the waste gas. After the above series of treatment steps, pollutants such as dust and harmful gases in the waste gas are effectively removed and discharged into the atmosphere after meeting the environmental protection discharge standards.
