Description

Technical Field

[0001] The invention belongs to the technical field of waste liquid processing, and in particular relates to an acrylonitrile waste liquid incineration and recycling system. Background Art

[0002] Acrylonitrile wastewater mainly comes from wastewater produced by acrylonitrile production, ABS plastic production, and thiamine production, and contains a large number of pollutants, such as acrylonitrile, acetonitrile, hydrocyanic acid, heavy components (polymers), ammonium sulfate, sodium carbonate, and catalyst powder. Acrylonitrile wastewater has complex components, high toxicity, and contains ammonium sulfate and salt. It is very difficult to treat. It is necessary to comprehensively consider nitrogen oxide emissions, sulfur corrosion, salt corrosion, and reasonable use of energy. Therefore, more complex treatment processes and systems can meet the requirements. At present, the commonly used industrial treatment methods for the above wastewater include biological methods, wet catalytic oxidation methods, and high-temperature incineration methods.

[0003] As for the high-temperature incineration method, it has the characteristics of simple process and efficient processing, strong adaptability to the flow rate and component fluctuations of acrylonitrile wastewater, and can achieve complete oxidation and decomposition of harmful substances in acrylonitrile wastewater. The specific description is: for waste liquid with calorific value, it is atomized into small droplets by compressed air through a waste liquid gun and then sprayed into the incinerator. Among them, the upper part of the incinerator is the reduction section. In the reducing atmosphere, more CN in the waste liquid is reduced to N2, and NOX is generated as little as possible. At the same time, some CO and H2 are produced. The lower section of the incinerator is the oxidation section. The high-temperature flue gas generated in the reduction section reacts with excess air, and is completely oxidized, burned, and decomposed into harmless or easy-to-handle components under the action of high temperature and turbulence.

[0004] In the prior art, when waste liquid is treated by high-temperature incineration method, not only a large amount of fuel is consumed to achieve the high temperature required for incineration, but also the operating cost is high, and the waste gas after combustion is generally discharged into the external environment after denitration treatment, resulting in energy waste. At the same time, for the combustion air transported to the incinerator, it needs to absorb a certain amount of heat in the furnace to heat up, and then play its combustion-supporting role, which affects the temperature environment in the incinerator to a certain extent, limits the incineration process, increases the combustion cost, affects the economic benefits in the factory, and cannot meet the use requirements. For this reason, a system for incinerating and recycling acrylonitrile waste liquid is provided, which has reasonable design, simple structure, convenient processing, and can centrally collect steam after incineration and denitration, and fully exchange heat in the transportation process of combustion air, so that it can obtain the temperature in front of the furnace in advance, and reduce the possibility of affecting the temperature in the incinerator. It can not only save fuel input and consumption, but also reuse steam energy to save resources, ensure the economic benefits of processing in the factory, and effectively meet the use requirements.

Detailed implementation manners

[0029] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0030] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0031] Embodiment, as Figures 1 to 10As shown in the figure, an acrylonitrile waste liquid incineration and reuse system is established at the end of an incinerator with a denitration device, and can especially receive the steam after denitration treatment. Further: it includes the reuse system device body, and the reuse system device body includes a tank group designed in a T shape. The tank group includes a heat exchange tank 1 set horizontally and a placement tank 2 set vertically. Among them, the heat exchange tank 1 is designed in a sandwich style. While improving its service strength, it can also ensure the effective completion of the heat exchange work. A steam inlet 1a is arranged below one side of the heat exchange tank 1, which is connected to the output end after acrylonitrile waste liquid is incinerated. Of course, before that, the aforementioned has undergone denitration treatment, so that it has a good use effect in the subsequent heat exchange process and will not affect the environment. Specifically: a heat exchange component is arranged in the heat exchange tank 1. The heat exchange component includes a turbulence component 3 for disturbing the hot steam and a conveying pipe group 4 for conveying the combustion-supporting air and designed in a U shape. The conveying pipe group 4 includes a plurality of conveying pipe monomers, and the monomers are designed in a U shape. Their two ends respectively correspond to the connecting pipes 55 in the air inlet component 5 and the air outlet component 6. While ensuring smooth conveying, it also improves the rationality of the arrangement of equipment components. Further, an air inlet component 5 is arranged on one side of the conveying pipe group 4, and an air inlet pipe 7 is arranged below it. An air outlet component 6 is arranged on the other side of the conveying pipe group 4, and an air outlet pipe 8 is arranged above it. The air inlet component 5 receives the combustion-supporting air conveyed by an external pump body and conveys it into the conveying pipe group 4. The air outlet component 6 receives the medium after the first heat exchange and conducts it into the next heat exchange process, fully ensuring the heat exchange effect and reducing the possibility of resource waste. A heat exchange pipe 9 designed in a reciprocating rotation shape is arranged in the placement tank 2. One end of the heat exchange pipe 9 penetrates into the heat exchange tank 1, and the other end penetrates to the outside of the placement tank 2. A combustion-supporting air supply pipe 10 designed in a mountain shape and connected to the air outlet component 6 is also arranged in the placement tank 2. The combustion-supporting air supply pipe 10 completes secondary heat exchange at the heat exchange pipe 9 and then inputs it into the external combustion-supporting pipeline. Considering that the conveying process of the combustion-supporting air in various pipelines only relies on an external pump body, in order to improve its conveying process, a pressurization component 11 is arranged above the placement tank 2 and connected to the end of the combustion-supporting air supply pipe 10. The establishment of the pressurization component 11 accelerates the flow process of the combustion-supporting air medium itself. Especially by using the high-low position conveying path of the medium and cooperating with the pressurization component 11, the medium is pressurized when being exported outward. In this way, the combustion-supporting air after heat exchange is pre-given a certain temperature, then is pressurized and exported through the pressurization component 11, and then is conveyed into the incinerator through the combustion-supporting air pipeline of the incinerator. To a certain extent, it reduces the possibility that the combustion-supporting air affects the temperature in the furnace. At the same time, it can also save the fuel input and consumption in the incinerator and ensure the economic benefits in the workshop;

[0032] In the above process: By using the established tank group, the processes of transporting the heat exchange and combustion-supporting media can be combined. On the one hand, the purpose of two-stage heat exchange can be achieved, reducing the possibility of resource waste. On the other hand, by using the established heat exchange component and the combustion-supporting gas supply pipe 10, the transportation process of steam and the combustion-supporting media is optimized, improving the functionality of the device and equipment, and providing a prerequisite for the smooth progress of subsequent incineration work. This device is reasonably designed, simple in structure, convenient to process, can centrally collect the steam after incineration and denitrification, and fully exchange heat in the process of transporting the combustion-supporting air, enabling it to obtain the pre-furnace temperature in advance and reducing the possibility of affecting the temperature in the incinerator. It can not only save the input and consumption of fuel, but also reuse the steam energy to achieve resource conservation, ensure the economic benefits of processing in the workshop, and effectively meet the usage requirements.

[0033] To further improve the rationality of the established device and equipment, the combustion-supporting gas supply pipe 10 includes a horizontal pipe 101 connected to the air outlet pipe 8. On one side of the horizontal pipe 101, there is a vertical pipe 102 designed in an L shape and penetrating through the heat exchange pipe 9. It makes secondary contact with the medium transported in the heat exchange pipe 9, that is, the heat exchange steam conducts a certain degree of heat exchange treatment on the vertical pipe 102 to avoid resource waste. Below the vertical pipe 102, there is a concave pipe 103 designed in a concave shape. Among them, one end of the two concave pipes 103 at the diagonal is higher than one end of the other two concave pipes 103 at the diagonal. Specifically described as: For the combustion-supporting air after heat exchange in the heat exchange tank 1, it makes further heat exchange contact with the heat exchange steam by means of the vertical pipe 102. The medium after secondary heat exchange is output to the outside through the concave pipe 103 to ensure the thoroughness of heat exchange and reduce the possibility of resource waste. In addition, for the high and low positions of the concave pipe 103 of the combustion-supporting gas supply pipe 10, its own transportation process can be used to achieve the purpose of increasing the speed, ensuring that it can be transported to the incinerator through the combustion-supporting pipeline more quickly, and to a certain extent ensuring the effective progress of the incineration work and improving the work process.

[0034] In order to relatively prolong the residence time of steam in the heat exchange tank 1 and fully ensure the heat exchange effect, the spoiler assembly 3 includes a circular plate 31 in the shape of a major arc, and its shape is designed to be larger than a semicircle, that is, its outer circumference is a major arc, so that the upper part can facilitate the passage of steam, and an extension plate 32132 is arranged above the circular plate 31, which is fixed to the circular plate 31, and a spoiler with a bent design is arranged on the outer side of the extension plate 32132. Multiple spoilers are equidistantly arranged along the outer circumference of the extension plate 32132, which can play a certain spoiler role on the steam in the transportation process and improve the heat exchange effect. Two adjacent spoiler assemblies 3 are centrally symmetrical, and multiple spoiler assemblies 3 are alternately arranged. After the multiple spoiler assemblies 3 are set up as described above, the steam with heat enters from the steam inlet 1a, and then flows in the heat exchange tank 1 in an S-shaped path. Under the condition of smooth transportation, the combustion air in the transportation pipe group 4 can be preheated to ensure the working process.

[0035] In order to guide the steam delivery process in the heat exchange tank 1, especially to ensure that it can be guided to the delivery pipe group 4 to ensure the heat exchange effect, a guide component 12 is arranged between two adjacent spoiler components 3, and the guide component 12 includes a guide plate 121 designed in an acute angle, which is located at the geometric center of the delivery pipe group 4 set up in a U shape, and promotes the steam delivery. The opening of the guide plate 121 near the steam inlet 1a is located at the top, and a guide cover 122 designed in a conical shape is arranged in the guide plate 121, and its opening is in the same direction as the opening of the guide plate 121. At the same time, for the multiple guide covers 122 set up For example, they are evenly distributed from top to bottom, and the two adjacent guide hoods 122 are staggered, the two adjacent guide components 12 are set up in a centrally symmetrical manner, and multiple guide components 12 are set up alternately. The specific description is: when the steam with heat is transported in accordance with the spoiler component 3, the steam flow direction is first collected to the inside of the guide plate 121, and then guided to both sides by the guide hood 122, especially acting on the adjacent conveying pipe group 4, to a certain extent ensure the effective realization of the heat exchange action, so that the smoothness of the heat exchange steam flow process can be guaranteed, and its action position can also be limited, thereby improving the working process and meeting the use requirements.

[0036] In order to facilitate the heat exchange process of the combustion-supporting air, the intake assembly 5 includes a pipe body 51 designed in a T shape. A ring plate 511 is arranged on the outer side of the pipe body 51. One side of the ring plate 511 is provided with an end shell 52 designed with an L-shaped cross section. An extension pipe 53 is arranged below the end shell 52. A disc 54 is arranged in the pipe body 51. A connecting pipe 55 designed in an L shape is arranged in the disc 54. One side of the connecting pipe 55 penetrates into the gap between the pipe body 51 and the end shell 52 and is communicated with the extension pipe 53. The other side of the connecting pipe 55 penetrates through the disc 54 and is connected to the delivery pipe group 4. Specifically described as follows: The equipment composition of the intake assembly 5 is the same as that of the outlet assembly 6. The difference lies in the installation direction of the extension pipe 53. Among them, the extension pipe 53 of the intake assembly 5 faces downward, and the extension pipe 53 of the outlet assembly faces upward to meet the delivery requirements in different delivery processes of the combustion-supporting air. Take the intake assembly 5 as an example: The external combustion-supporting air is delivered to the heat exchange tank 1 by a pump body, especially input into the extension pipe 53 through the intake pipe 7. The combustion-supporting air medium is delivered and fills the end shell 52. Due to the arrangement of each connecting pipe 55, the combustion-supporting air medium is input from one end of the connecting pipe 55 and delivered to the delivery pipe group 4 to ensure the smooth progress of the heat exchange work. Further, one connecting pipe 55 corresponds to one delivery pipe, and their arrangement methods are the same, which not only ensures the smoothness of the delivery process but also improves the rationality of the installation of the device equipment. Correspondingly, for the outlet assembly 6, the installation methods of each device are the same as those of the intake assembly 5. The difference is that after the heat-exchanged combustion-supporting air medium is delivered to the connecting pipe 55 in the outlet assembly 6 along the delivery pipe group 4, it is then centrally delivered in the end shell 52, and finally output by the extension pipe 53 and connected to the outlet pipe 8. Furthermore, the heat-exchanged combustion-supporting air can be input into the combustion-supporting air delivery pipe 10, providing a prerequisite for its secondary heat exchange, fully reducing the possibility of resource waste. At the same time, the installation of the same structure for the intake assembly 5 and the outlet assembly 6 can achieve multi-purpose use of one machine, improve its use functionality, and save costs.

[0037] In order to achieve the pressurized export of the combustion-supporting air after heat exchange to improve its transportation process, the pressurization assembly 11 includes an annular pipe 111, and its upper part is connected to the concave pipe 103 located at a high position. A confluence member 112 is arranged below the annular pipe 111 and is communicated with the concave pipe 103 located at a low position. A first speed-increasing shell 113 with an arc-shaped cross-section is arranged above the confluence member 112. A lead-out shell 114 with an L-shaped cross-section is arranged above the first speed-increasing shell 113. A second speed-increasing shell 115 is arranged below the lead-out shell 114 and is located between the annular pipe 111 and the first speed-increasing shell 113. Among them, the lower half of the cross-section of the second speed-increasing shell 115 is also designed in an arc shape, and the upper half of its cross-section is designed in an L shape. An air vent groove 1131 designed with an inner opening is arranged on the first speed-increasing shell 113. The specific description is as follows: For the combustion-supporting air transported to the pressurization assembly 11 at a low position, it converges at the confluence member 112 and is guided from the outside of the confluence member 112 into the first speed-increasing shell 113. For the air medium entering the first speed-increasing shell 113, its transportation path changes from a large diameter to a small diameter, then to a large diameter, and finally is transported through the lead-out shell 114 to the combustion-supporting pipe of the external incinerator to achieve the combustion-supporting effect in the incinerator. For the combustion-supporting air transported to the pressurization assembly 11 at a high position, it is first transported between the annular pipe 111 and the lead-out shell 114 and flows downward, and then flows out from the gap between the second speed-increasing shell 115 and the first speed-increasing shell 113. When passing through the second speed-increasing shell 115, the combustion-supporting air is introduced from a large-diameter part and flows towards a small-diameter part, and then is guided towards a large-diameter part, achieving a certain degree of speed increase for the combustion-supporting air led out at a high position. Finally, it is led out through the air vent groove 1131 and is led out together with the combustion-supporting air in the first speed-increasing shell 113. The two promote each other and are input into the incinerator together, achieving a certain degree of speed increase and export of the combustion-supporting air medium, ensuring the effective progress of the combustion work and meeting the use requirements.

[0038] In order to enable the combustion-supporting air after heat exchange to be smoothly discharged and improve its smoothness during the discharge process, the confluence member 112 includes a mounting shell 1121 designed in a Z shape. A confluence shell 1122 designed in an obtuse angle shape is provided below the mounting shell 1121, and the lower part of the confluence shell 1122 is designed in an arc shape. Among them, a buffer groove with a right trapezoidal cross-section is formed between the inner side of the mounting shell 1121 and the outer side of one end of the confluence shell 1122. On the one hand, the combustion-supporting air can extend outward under the collection effect below the confluence shell 1122, and on the other hand, it is concentrated at the above-mentioned buffer groove, which not only plays a buffering role but also provides a prerequisite for guiding it into the first speed-increasing shell 113. Further speaking: A steady flow body 1123 designed in a hemispherical shape is provided above the confluence shell 1122, which can, to a certain extent, reduce the collision of the medium introduced from below into the first speed-increasing shell 113 and affect the conveying process. Further speaking, a flow-dispersing groove 11221 is opened at the bending part of the confluence shell 1122, so that the medium concentrated at the buffer groove can be smoothly conveyed into the pressurization assembly 11, which facilitates improving its conveying speed.

[0039] In order to fully complete the convenient adjustment of the steam flow for heat exchange work input, an adjustable valve 13 is provided on the heat exchange tube 9 above the intake assembly 5 and the outlet assembly 6. The adjustable valve 13 includes an annular shell 131 with a concave cross-section design. A stabilizing frame 132 is provided inside the annular shell 131. One end where multiple stabilizing frames 132 converge is provided with a cover body 133. Among them, the cover body 133 is composed of two parts and is connected together by bolts. One end of the stabilizing frame 132 is fixedly connected to the cover body 133, and the other end is connected to the annular shell 131 by bolts to ensure the stability of its position. In addition, a shaft body penetrating into the cover body 133 is provided on one side of the rotating flap 134 close to the cover body 133 and is rotatably connected to the cover body 133 to ensure the smoothness of its subsequent rotation. A plurality of fan-shaped rotating flaps 134 are evenly arranged on the cover body 133. A rotating shaft 135 is provided on the other side of the rotating flap 134 and penetrates through the annular shell 131. A bearing seat 138 is provided on the outer periphery of the annular shell 131 and is connected to the rotating shaft 135. A connecting plate 136 is provided at the upper end of the rotating shaft 135. A spherical connecting rod 137 is provided between adjacent two connecting plates 136. The two spherical connecting rods 137 on the same connecting plate 136 are arranged staggeredly front and back. Further, the specifications of the rotating flaps 134 can be set to different sizes according to different usage requirements. Multiple rotating flaps 134 of the same size specification form a cylindrical shape and are adapted to the inner side of the annular shell 131, and can cut off the heat exchange steam when fully closed. In the use state, when the rotating flaps 134 are in different positions, different amounts of steam can be ensured to be exported, realizing the controllability of the heat exchange process; in addition, for the set rotating shaft 135, the connecting shaft 141 on the rotating shaft 135 close to the mounting plate 14 bears the driving power. The rotating shaft 135 rotates with the connecting shaft 141 and can drive the connecting plate 136 to rotate relative to the bearing seat 138, and can rotate reciprocally to a certain extent to facilitate the adjustment of the rotating flaps 134 in different positions, that is, the adjustment angle of the rotating flaps 134 can be freely adjusted. For the adjustment between adjacent two rotating flaps 134, the two staggeredly arranged spherical connecting rods 137 can drive the synchronous rotation of the adjacent two connecting plates 136, and at the same time can make the rotation angles of multiple rotating flaps 134 consistent, fully ensuring the use functionality of the device and equipment.

[0040] In order to further improve the rationality of the installation of the device, an installation plate 14 designed in a concave shape is provided on one side of the ring shell 131. A connecting shaft 141 is arranged inside the installation plate 14.
