Abstract
Description
Technical Field
[0001] The invention relates to the technical field of a nitre reaction heat treatment device, and in particular to a circulating water cooling type nitre reaction device and process. Background Art
[0002] Dinitrochlorobenzene is a chemical agent, a hapten, which can covalently bind to the soluble part of epithelial protein to form a complete antigen. It is a light yellow crystalline powder, soluble in acetone. In the production process of dinitrochlorobenzene, the materials in the nitric acid mixed high-level tank and the acid chlorobenzene high-level tank are respectively pumped into the nitric microchannel reactor by two metering pumps in proportion to carry out the nitric reaction (the chlorobenzene reaction conversion rate of this process is about 95%, the liquid holding capacity of one microchannel reactor is 1.5L, the material stays in the microchannel reactor for 2 to 10 seconds; the feed pressure of the microchannel reactor is 0.3 to 2.0MPa, and the discharge pressure is about 0.1MPa; the feed temperature of the microchannel reactor is about 45℃, and the discharge temperature is 100 to 180℃). The mixed material after passing through the microchannel reactor enters a tubular reactor to continue the reaction, and then enters the tubular reactor to continue the reaction and is indirectly cooled by circulating water to improve the material conversion rate.
[0003] At present, there are still some shortcomings in cooling the nitrate reaction materials through tube-circulating water: At present, when circulating water cooling is performed, the inside of the tubular reactor shell needs to be filled with cooling water, and the heat exchange tubes arranged inside the shell are covered by the cooling water, so as to complete the heat exchange of the materials inside the heat exchange tubes. However, in this process, due to the large internal space of the tubular reactor shell, a large amount of circulating water is required, and the fluidity of the water is poor, resulting in low heat exchange efficiency; After a long period of water cooling, scale will continue to accumulate on the outer surface of the heat exchange tube, and material residue will continue to accumulate on the inner surface of the heat exchange tube, which will cause the heat exchange performance of the heat exchange tube to continue to decrease, thus affecting the heat exchange efficiency of the material; The material flowing through the heat exchange tube is in a stable flow state, which makes the contact surface between the material and the inner wall of the heat exchange tube relatively single, and it is impossible to exchange heat well at the center of the flowing material, making the heat exchange uniformity of the material poor and insufficient.
[0004] In view of this, the present invention proposes a circulating water cooling type nitrate reaction device and process. Summary of the invention

[0015] A process for a circulating water cooling type nitrate reaction device comprises the following steps: S1. Connect the raw material barrel containing the material after the nitrate reaction to the pipe end on the conveying mechanism through a pipeline, and inject external cooling water into the first circulating water storage chamber through the circulating water inlet pipe. As the water pressure inside the first circulating water storage chamber gradually increases, the cooling water inside the first circulating water storage chamber will be transported to the inside of the second circulating water storage chamber through the circulating water pipe, and finally discharged through the circulating water outlet pipe, thereby forming a cycle, and the outer wall of the material pipe is circulated and cooled by the circulating cooling water; S2, turn on the power supply, start the motor, the motor drives the drum to rotate through its output shaft, the drum drives the small bevel gear to rotate, the small bevel gear drives the large bevel gear to rotate on the top of the support plate, the large bevel gear drives the mounting plate to revolve, the mounting plate pushes and pulls the supporting column through the connecting rod, the supporting column pulls the reciprocating rod inside the drum through the supporting block, and pushes and pulls the piston seat inside the temporary storage cylinder through the push-pull frame, when the piston seat is pulled back, the one-way valve on the upper side is opened, the one-way valve on the lower side is closed, and the material is drawn into the temporary storage cylinder through the pipe end, then, when the piston seat is pushed forward, the one-way valve on the upper side is closed, the one-way valve on the lower side is opened, so that the material inside the temporary storage cylinder will pass through and merge into the first material storage chamber, then, the material inside the first material storage chamber flows into the second material storage chamber through the material pipe, in this process, since the material pipe is arranged on the inner side of the circulating water pipe, the cooling water circulating inside the circulating water pipe can exchange heat with the material in the material pipe; S3. When the motor drives the drum to rotate, the drum can drive the fan to rotate, sucking the external airflow into the air guide frame through the air inlet, and sending it into the air chamber through the air inlet, blowing air to the outer wall of the circulating water pipe inside the air chamber, thereby accelerating the loss of heat in the circulating water pipe and reducing the temperature of the cooling water flowing through the circulating water pipe; S4.

By providing the circulating water pipe and introducing cooling water into the circulating water pipe, the amount of circulating water can be reduced and the flow rate of water can be increased, thereby quickly removing the temperature. In addition, a wind-cooling drive mechanism is provided on the upper side of the cooling cylinder. When the wind-cooling drive mechanism is working, the motor drives the rotating cylinder to rotate through its output shaft. During the rotation of the rotating cylinder, the rotating cylinder can drive the fan to rotate, and the external airflow is sucked into the air guide frame through the air inlet, and is sent into the wind chamber through the air inlet, thereby blowing air to the outer wall of the circulating water pipe inside the wind chamber, thereby accelerating the loss of heat in the circulating water pipe and reducing the temperature of the cooling water flowing through the circulating water pipe. In the present invention, a conveying mechanism is arranged on the upper side of the second end cover, and a transmission mechanism is arranged between the conveying mechanism and the air-cooling driving mechanism. During the operation of the air-cooling driving mechanism, the conveying mechanism can be driven by the transmission mechanism, so that while the air-cooling driving mechanism air-cools the interior of the air chamber, the conveying mechanism can intermittently deliver the material to be cooled in the mononitro reaction to the interior of the first material storage chamber, thereby realizing continuous delivery of the material without the need for additional power equipment, thereby saving costs. In the present invention, a stirring and scraping mechanism is provided on the second end cover. In the process of the transmission mechanism driving the conveying mechanism, the stirring and scraping mechanism can be driven by the conveying mechanism, and the outer scraping ring on the stirring and scraping mechanism can scrape and clean the outer wall of the material pipe, so as to avoid the accumulation of scale on the outer wall of the material pipe by the circulating cooling water after a long period of work, resulting in reduced heat exchange efficiency. The inner scraping ring that moves back and forth can scrape and clean the inner wall of the material pipe, so as to avoid the accumulation of sediment on the inner wall of the material pipe after a long period of work, and the reciprocating support rod can sway the material flowing inside the material pipe, so that the material in contact with the inner wall of the material pipe can be constantly changed, thereby improving the uniformity of the material heat exchange, making the heat exchange more sufficient and efficient.

The reciprocating support rod 424 can sway the material flowing inside the material pipe 8, so that the material in contact with the inner wall of the material pipe 8 can be constantly changed, thereby improving the uniformity of the heat exchange of the material and making the heat exchange more sufficient.
[0034] Working principle and usage process: When working, the raw material barrel containing the material after the nitre reaction is connected to the pipe end 55 on the conveying mechanism 5 through a pipeline, and the external cooling water is injected into the first circulating water storage chamber 15 through the circulating water inlet pipe 17. As the water pressure inside the first circulating water storage chamber 15 gradually increases, the cooling water inside the first circulating water storage chamber 15 will be transported to the inside of the second circulating water storage chamber 14 through the circulating water pipe 9, and finally discharged through the circulating water outlet pipe 16, thereby forming a cycle, and the outer wall of the material pipe 8 is circulated and cooled by the circulating cooling water.
[0035] After that, the power is turned on and the motor 72 is started. The motor 72 drives the rotating drum 74 to rotate through its output shaft, and the rotating drum 74 drives the small bevel gear 61 to rotate. The small bevel gear 61 drives the large bevel gear 67 to rotate on the top of the support plate 62, and the large bevel gear 67 drives the mounting plate 68 to revolve. The mounting plate 68 pushes and pulls the supporting column 65 through the connecting rod 66. The supporting column 65 pulls the reciprocating rod 63 inside the rotating drum 74 through the supporting block 64, and pushes and pulls the piston seat 52 inside the temporary storage cylinder 53 through the pushing and pulling frame 51. When the piston seat 52 is pulled back, the one-way valve 56 on the upper side opens. Open, the one-way valve 56 on the lower side is closed, and the material is drawn into the temporary storage tube 53 through the connecting pipe end 55. Then, when the piston seat 52 is pushed forward, the one-way valve 56 on the upper side is closed, and the one-way valve 56 on the lower side is opened, so that the material inside the temporary storage tube 53 will flow into the first material storage chamber 31. Then, the material inside the first material storage chamber 31 flows into the second material storage chamber 21 through the material pipe 8. In this process, since the material pipe 8 is arranged on the inner side of the circulating water pipe 9, the cooling water circulating inside the circulating water pipe 9 can exchange heat with the material in the material pipe 8. While the motor 72 drives the drum 74 to rotate, the drum 74 can drive the fan 75 to rotate, sucking the external air flow into the air guide frame 73 through the air inlet 76, and sending it into the air chamber 11 through the air inlet 13, blowing air on the outer wall of the circulating water pipe 9 in the air chamber 11, thereby accelerating the loss of heat in the circulating water pipe 9 and reducing the temperature of the cooling water flowing through the circulating water pipe 9.
[0036] During the process of the push-pull frame 51 pushing and pulling the piston seat 52 inside the temporary storage tube 53, the piston seat 52 pushes and pulls the push-pull rod 411, and the push-pull rod 411 pushes and pulls the horizontal axis 415 through the connecting rod 412. The horizontal axis 415 drives the outer ring 413 and the vertical plate 414 to reciprocate. During the reciprocating movement of the vertical plate 414, the first mounting shaft 421 and the second mounting shaft 422 can be reciprocated, thereby driving the support rod 424, the inner scraper ring 425 and the outer scraper ring 423 to reciprocate. The reciprocating outer scraper ring 423 can scrape and clean the outer wall of the material pipe 8 to avoid the accumulation of scale on the outer wall of the material pipe 8 by the circulating cooling water after a long period of work, resulting in reduced heat exchange efficiency. The reciprocating movement of the support rod 424 and the inner scraper ring 425 can scrape and clean the inner wall of the material pipe 8 through the reciprocating inner scraper ring 425, so as to avoid the accumulation of sediment on the inner wall of the material pipe 8 after a long period of work. The reciprocating support rod 424 can sway the material flowing inside the material pipe 8, so that the material in contact with the inner wall of the material pipe 8 can be constantly changed, thereby improving the uniformity of the heat exchange of the material and making the heat exchange more sufficient.
