Description

Technical Field

[0001] The invention relates to the technical field of heat exchange equipment, and more specifically to a triple-effect energy-saving evaporator. Background Art

[0002] The three-effect energy-saving evaporator is a highly efficient and environmentally friendly evaporation equipment. It achieves energy conservation and efficiency improvement through optimized design and technical improvement. This evaporator has broad application prospects in industrial production, which helps to reduce production costs and improve economic benefits.

[0003] The design of the three-effect energy-saving evaporator takes into account the multiple utilization of heat energy in the evaporation process. In the traditional single-effect evaporator, after the primary steam is used to heat the raw materials, its condensed water and unused heat are usually discharged, resulting in energy waste. In the three-effect system, the first evaporator (called the first effect) uses raw steam for heating, and the secondary steam generated is transported to the second evaporator (the second effect) as its heating source. Similarly, the secondary steam generated by the second effect is used in the third evaporator (the third effect). By connecting the three evaporators in series, each portion of heat energy can be used multiple times within the system, greatly improving the overall energy efficiency ratio.

[0004] However, during the operation of the evaporator, the temperature difference between the top and bottom of the internal chamber causes the water vapor to encounter the colder top wall of the chamber during its rise, which causes the water vapor to condense. The condensed water vapor turns into tiny water droplets, which gradually gather on the top wall. However, these water droplets need to accumulate to a certain volume before they can form droplets large enough to flow back to the bottom of the chamber. This process undoubtedly increases the evaporation cycle and reduces the evaporation efficiency. In addition, the natural heating evaporation method will cause the static solution to be heated unevenly. This temperature unevenness will directly affect the evaporation rate of the solvent molecules in the solution. In areas with higher temperatures, the kinetic energy of the solvent molecules is larger, and it is easier to overcome the attraction of the liquid surface and escape to become gas, thereby accelerating the evaporation process. On the contrary, in areas with lower temperatures, the kinetic energy of the solvent molecules is smaller, and the evaporation rate is correspondingly slowed down, resulting in an unstable evaporation rate.

[0005] Therefore, a new triple-effect energy-saving evaporator is urgently needed. Summary of the invention

[0027] In this embodiment, it should be specifically explained that the side walls of the transformer chamber 103 and the transition chamber 104 are movably penetrated by the connecting rod 603, and the outer end of the sliding block 604 extends at least beyond the position of the front wall of the body 1, so that the bidirectional screw rod 701 can penetrate the left and right sliding blocks 604, thereby transmitting the left and right efficiency-enhancing components 6 to move toward or away from each other; A water collection tank is provided at the bottom of the transition chamber 104. The cleaning brushes 602 moving in opposite directions scrape the inner wall of the transition chamber 104, and the condensed water droplets on the inner wall of the transition chamber 104 are scraped off and fall into the water collection tank at the bottom of the transition chamber 104, and then transported to the inner cavity of the evaporation chamber 101 through the one-way reflux pipe. There is a gap between the fixing rod 805 and the channel for steam to flow, and the surface of the lining plate 804 has holes and grooves for steam to flow.

[0028] Working principle of the present invention: When the evaporator heats and evaporates the solution injected into the inner cavity of the evaporation chamber 101, the output shaft of the servo motor 704 drives the driving gear 703 connected thereto to rotate forwardly, and the rotating driving gear 703 transmits the driven gear 702 meshing therewith, causing the driven gear 702 and the bidirectional screw rod 701, which are coaxially sleeved, to spin, causing the efficiency-enhancing components 6 arranged in mirror images on the left and right to move toward each other along the bidirectional screw rod 701 with the help of the sliding block 604, and the piston plates 601 moving toward each other continuously compress the transverse bellows 801, so that the gas in the inner cavity of the transverse bellows 801 is rapidly discharged. The water droplets are transferred to the longitudinal bellows 802, which causes the longitudinal bellows 802 to extend and push the lining plate 804, the fixing rod 805 and the sealing plate 806 connected thereto to move upward, so that the sealing plate 806 quickly seals the vent pipe 803. At the same time, the cleaning brush 602 moving in opposite directions scrapes the inner wall of the transition chamber 104, scrapes off the condensed water droplets on the inner wall of the transition chamber 104 and drops them into the water collection tank at the bottom of the transition chamber 104, and then transports them to the inner cavity of the evaporation chamber 101 through the one-way reflux pipe, thereby accelerating the reflux of water droplets on the top wall of the equipment chamber, shortening the evaporation cycle, and improving the evaporation efficiency. After the sealing plate 806 seals the vent pipe 803, along with the continuous displacement of the piston plate 601, the high-pressure airflow compressed in the pressure-changing chamber 103 will be introduced downward into the drainage chamber 102 connected thereto, and the high-pressure airflow drives the coaxially arranged impeller 502, the roller shaft 501 and the stirring plate 503 to spin, and the spinning stirring plate 503 stirs the solution in the inner cavity of the evaporation chamber 101 to improve the uniformity of the heating of the solution and maintain the stability of the evaporation rate, while part of the high-pressure airflow condenses in the drainage chamber 102 and is then transported to the inner cavity of the evaporation chamber 101 through the one-way reflux pipe; Subsequently, the output shaft of the servo motor 704 drives the driving gear 703 connected thereto to rotate in the opposite direction, causing the efficiency-enhancing components 6 arranged in mirror images on the left and right to move in opposite directions along the bidirectional screw rod 701 by means of the sliding block 604, and the gas in the inner cavity of the longitudinal bellows 802 is transferred to the transverse bellows 801 again, and the longitudinal bellows 802 contracts and pulls the lining plate 804, the fixing rod 805 and the sealing plate 806 connected thereto to move downward, causing the sealing plate 806 to separate from the vent pipe 803, and at the same time, the cleaning brushes 602 moving in opposite directions are reset to the two sides of the transition chamber 104, waiting for the next cycle to clean the water droplets on the top wall of the equipment chamber; When the sealing plate 806 is separated from the vent pipe 803, the piston plate 601 continues to move in opposite directions, and the pressure in the pressure-changing chamber 103 is reduced, which speeds up the steam in the evaporation chamber 101 to be introduced into the pressure-changing chamber 103 through the steam delivery pipe 4. The steam entering the pressure-changing chamber 103 passes through the gaps between the lining plate 804, the fixing rod 805 and the sealing plate 806 in turn, and is introduced into the inner cavity of the transition chamber 104 through the vent pipe 803, and then is guided into the lower-stage evaporator from the steam discharge pipe 3 connected to the side wall of the transition chamber 104. The device reciprocates to perform the above-mentioned cycle steps to improve the uniformity of heating of the solution and accelerate the reflux of water droplets on the top wall of the device chamber, so as to reduce the evaporation time and improve the evaporation efficiency and stability.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or modifications within the technical scope disclosed by the present invention; according to the technical plan and its improved conception of the present invention, all of which should be included under the protection of the present invention.
