Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steam recovery, in particular to an organic synthesis steam recovery device. BACKGROUND

[0002] In the organic synthesis industry, chemical reactions, distillation, evaporation and other processes will produce a large amount of high-temperature steam carrying organic matter. These steams not only contain a large amount of recoverable latent heat, but also contain important chemical raw materials or potential pollutants. Efficient recovery of heat energy, moisture and organic matter in the steam can not only reduce energy consumption and cost in the production process, but also reduce the emission of volatile organic compounds and meet the requirements of environmental regulations.

[0003] At present, conventional steam recovery devices, such as tubular condensers and plate heat exchangers, have difficulty in separating organic impurities when processing organic synthesis steam. The condensed water formed after the condensation of organic synthesis steam often contains trace amounts of suspended solids, oily organic matter or slightly soluble impurities. Traditional devices lack targeted air flotation separation steps and rely only on gravity settling or simple filtration, which cannot effectively remove organic particles with a density close to water and a small particle size. This results in high turbidity and excessive organic content of the recovered condensed water, which cannot be directly reused in process steps with high water quality requirements, often requiring additional water treatment costs. SUMMARY

[0006] Further, the spiral cold water pipe is made of pure copper material, and the thermal conductivity of copper is as high as 401 W / (m·K), which is 8-10 times that of ordinary steel pipe, which can effectively increase the heat exchange effect of steam and cooling water, shorten the heat transfer time through high thermal conductivity material, and make the steam release latent heat and condense quickly after contacting the pipe wall.

[0007] Further, the spiral partition plate is connected between the inner wall of the steam recovery tank and the outer wall of the air floatation separation tank, and the annular gap is divided into a spiral channel through the spiral partition plate; the spiral direction of the spiral partition plate is consistent with the spiral direction of the spiral cold water pipe, and the same direction design matches the steam flow direction with the spiral direction of the cold water pipe to avoid flow interference; the spiral pitch of the spiral partition plate is consistent with the spiral pitch of the spiral cold water pipe, and the equal pitch design ensures that the steam maintains uniform contact distance with the surface of the cold water pipe during flow; the spiral cold water pipe is located in the gap of the spiral partition plate, and the steam flows along the spiral channel in a serpentine manner through the constraint of the partition plate, thereby increasing the steam flow distance and increasing the steam flow path length to 3-5 times the height of the tank body, increasing the contact time of steam with the spiral cold water pipe, and prolonging the contact time from 5-8 seconds of straight pipe type to 15-20 seconds, thereby improving the condensation effect, and the actual measurement shows that the condensation efficiency is increased by more than 40% compared with the structure without the partition plate.

[0008] Further, the steam inlet is located above the spiral partition plate to ensure that the steam enters the spiral channel directly after entering the steam recovery tank; and the gas overflow port is located below the spiral partition plate, so that the steam must pass through the entire spiral channel before being discharged from the overflow port, thereby ensuring that the steam can pass through the entire spiral partition plate completely after entering the steam recovery tank, and avoiding the phenomenon of insufficient condensation caused by short path flow of the steam.

[0009] Further, the steam flows from top to bottom in the steam recovery tank, and the cooling water flows from bottom to top in the spiral cold water pipe, forming a counter-flow heat exchange mode, so that the steam and the condensing water form a convection, and the temperature difference between the steam and the cooling water is maximized in the entire heat exchange process, and the heat exchange efficiency is increased by 25%-30% compared with the convection mode, thereby improving the condensation effect and increasing the steam condensation amount by more than 30% per unit time.

[0010] Further, a gas distribution plate is embedded at the gas overflow port as a key component for bubble breaking; the gas distribution plate is made of high-temperature sintered porous ceramic material with a porosity of 40%-50%, and the pore size is uniformly distributed in 50-100 μm, which can refine the steam bubbles, break the initial bubbles with a diameter of 5-10 mm into small bubbles with a diameter of 0.1-0.5 mm, increase the contact area between the bubbles and the condensing water by 10-20 times, and significantly improve the mass transfer efficiency.

[0012] Further, the condensate overflow port is located below the gas overflow port, and the impurities in the lower area have been mostly floated after the gas floatation separation, so that the condensate overflowed from the condensate overflow port is relatively pure, and the turbidity is reduced by more than 80% compared with that at the gas overflow port.

[0013] Further, the overflow elbow is in the same height as the organic matter overflow port, and the liquid level linkage control is realized through the same height design, so that the water level height in the gas floatation separation tank can be in the same height as the overflow elbow and the organic matter overflow port, the organic matter foam layer and the condensate overflow surface are synchronously raised, the condensate is flowed out from the overflow elbow at the same time, the organic matter foam can also be flowed out from the organic matter overflow port, the foam is not discharged in time or the condensate is excessively lost due to the liquid level deviation is avoided.

[0014] Further, the gas pressure balance valve is arranged at the overflow elbow, the gas pressure difference inside and outside the elbow is adjusted through the valve, so that the gas pressure difference between the overflow elbow and the outside is balanced, the inside and outside pressure difference is controlled within ±50Pa, the vacuum formed at the overflow elbow is prevented to hinder the condensate flow, the condensate flow rate is stabilized, and the flow interruption or flow rate fluctuation caused by the vacuum is avoided.

[0015] Compared with the prior art, the beneficial effects of the present application include: The organic synthesis steam recovery device provided by the present application can effectively refine the steam bubbles through the inclined porous ceramic gas distribution plate at the gas overflow port by special structure design, the larger initial bubbles are broken into smaller bubble groups. These small bubbles form more sufficient contact with the condensate during the rising process, greatly increasing the mass transfer area of the gas-liquid two-phase, so that the steam which is not completely condensed can release latent heat and complete deep condensation in the gas floatation separation tank, significantly improving the thoroughness of the overall steam recovery, and the small bubbles produced during the rising process can effectively capture and carry the organic impurities to the liquid surface. With the continuous aggregation of the bubbles, the impurities gradually form a stable foam layer, and finally realize directional collection through the organic matter overflow port. This process is realized through the synchronous liquid level control design of the overflow elbow and the organic matter overflow port, which ensures the dynamic balance of the foam layer and the condensate liquid surface, avoids the secondary pollution of impurities caused by the residual foam, prevents the problem of excessive impurities entrained by the condensate, and realizes the precise separation of organic matter and pure condensate.

[0020] Working principle: The device realizes steam heat recovery and organic impurity removal through a three-stage condensation separation system. The core process is divided into three stages: steam pre-condensation, air floatation deep treatment, and liquid-gas-slag three-phase separation. The specific working principle is as follows: 1. Steam recovery tank 1 pre-condensation After the steam enters from the steam inlet 7, it flows spirally from top to bottom along the gap between the spiral partition 3, forming a winding path of 3-5 times the height of the tank. The cooling water in the spiral cooling water pipe 5 is pumped in from the water inlet 4, and flows spirally upward against the flow, forming a 180° counter-flow with the steam. The copper material pipe wall has a heat transfer coefficient of 401 W / (m·K), which is higher than the ordinary steel pipe. The spiral partition 3 and the cooling water pipe 5 are designed with the same pitch and the same rotation direction, which makes the steam form a turbulent flow between the partitions, prolongs the contact time, and improves the condensation efficiency compared with straight pipe type.

[0021] The steam condenses on the outer surface of the spiral cooling water pipe to form a liquid film, which converges to the bottom of the steam recovery tank. When the condensate level reaches the height of the gas overflow port 8, the subsequent steam continues to enter, causing the pressure in the tank to rise, which pushes the condensate through the gas overflow port 8 into the air floatation separation tank 2, forming a dynamic liquid level balance. 2. Bubble refinement and condensation enhancement The steam and non-condensable gas that has not been completely condensed pass through the gas overflow port 8, first through the embedded inclined 30°-60° gas distribution plate 9, which refines the bubble size to 0.1-0.5mm, increasing the specific surface area of the bubbles. The inclined design ensures efficient mass transfer throughout the tank. The refined bubbles in the air-liquid secondary condensation process are in contact with the condensate water in the air floatation separation tank, and the steam components continue to condense on the surface of the liquid film: The bubble rising path is as long as 150-200cm, with a residence time of 3-5 seconds, which increases the condensation time compared with the traditional straight type; 3. Air floatation separation During the bubble rising process, the air floatation force is generated, which drives the organic impurities in the condensate water to adhere to the surface of the bubbles, forming a gas-liquid composite phase: When the impurity particle size is ≥5μm, the adhesion efficiency is 95%, and the bubbles rise to the top of the air floatation separation tank; When the foam layer thickness reaches 5-10cm, it enters the separation pipe 11 through the organic matter overflow port 12, and is finally collected from the organic matter outlet 13, realizing impurity separation. The pure condensate water sinks to the bottom of the air floatation separation tank, and flows into the curved drain pipe 15 through the condensate overflow port 14 located 5-10cm below the gas overflow port 8: The overflow elbow 16 is at the same height with the organic matter overflow port 12, so as to ensure that the liquid level is stable at the set height; The air pressure balance valve 17 maintains the air pressure balance inside and outside the overflow port, prevents the vacuum from hindering the flow, and finally recycles the clean condensed water from the discharge port 18. 4. Waste gas and excess pressure treatment The uncondensed non-condensable gas, such as air, inert gas and the like, rises to the top end of the air floatation separation tank, is connected to a waste gas recycling system through the exhaust valve (10), is treated by activated carbon adsorption or incineration, and is discharged after reaching the standard; the whole process of the steam flow path forms a closed loop treatment of spiral condensation, bubble refinement, air floatation separation and gradient discharge, so as to realize the dual goals of heat energy recovery and environmental protection discharge.

[0022] The technical scope of the present application is not limited to the content in the above description, and those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical idea of the present application, and these modifications and changes should all belong to the protection scope of the present application.
