Description

Technical Field

[0001] This utility model relates to the technical field of solution concentration equipment, specifically a calcium bromide solution concentration device. Background Technology

[0002] The need for calcium bromide solution concentration is widespread across numerous industries. For example, in the recycling of electronic circuit boards, the calcium bromide solution converted from hydrogen bromide requires concentration; in pharmaceutical production, concentration is necessary to achieve the required concentration for preparing pharmaceutical-grade calcium bromide; in offshore oil drilling fluid preparation, obtaining a suitable solution from calcium bromide-containing brine also relies on concentration operations; and in chemical production, the production of calcium bromide from tetrabutylammonium bromide crystallization mother liquor also necessitates a concentration process. However, existing calcium bromide solution concentration equipment has many shortcomings.

[0003] From the perspective of concentration efficiency, the internal structure design of the evaporator in traditional concentration equipment has flaws. The flow path of the solution within the evaporator is chaotic, lacking a reasonable diversion and guidance mechanism, resulting in the inability of the solution to form a stable and uniform film within the heat transfer tubes. When hot steam is introduced, the contact area between the solution and the hot steam is limited, leading to low heat exchange efficiency and significantly extended concentration time. In large-scale production scenarios, this inefficient concentration method severely restricts production progress and cannot meet the output demands of enterprises. For example, in the electronic circuit board recycling industry, large quantities of calcium bromide solutions require rapid concentration, but traditional equipment struggles to achieve efficient operation.

[0004] In terms of steam treatment and equipment stability, the condensation mechanism of traditional units is too simple. The heat exchange area is small, and steam cannot fully contact the cooling medium after entering the condensation zone, resulting in a slow condensation rate. This not only affects the timely discharge of steam during the concentration process but also causes internal pressure fluctuations, seriously threatening the stable operation of the unit. If steam cannot condense in time, it may accumulate inside the equipment, causing a series of safety hazards and reducing the equipment's service life. For example, in the concentration units used on offshore oil exploration platforms, the harsh working environment places extremely high demands on equipment stability, which traditional simple condensation structures cannot meet, leading to frequent malfunctions and affecting production operations. Therefore, there is an urgent need to improve a calcium bromide solution concentration unit to solve these problems. Utility Model Content

[0009] Preferably, a liquid storage chamber is provided above the baffle, an inlet pipe is fixedly installed at the top of the concentration tower, a steam inlet pipe is fixedly installed on the side of the concentration tower, the steam inlet pipe is fixedly installed between the baffle and the partition plate, a concentration chamber is provided below the partition plate, a steam outlet pipe is fixedly installed at the position of the concentration chamber, a condenser is fixedly installed on the partition plate, a concentration outlet pipe is fixedly installed at the bottom of the concentration tower, and a valve is fixedly installed on the concentration outlet pipe.

[0010] Preferably, the condensing mechanism includes a steam outlet pipe, the end of which is fixedly installed inside the evaporator. The evaporator is provided with an evaporation chamber, and a condensing device is fixedly installed inside the evaporation chamber.

[0011] Preferably, the condensing device includes condensing fins, a first condensing tube is fixedly installed inside the condensing fins, one end of the first condensing tube is fixedly installed at the outlet of the water pump, the other end of the first condensing tube is fixedly installed inside the water tank, the evaporator is connected to the water tank through a second condensing tube, and the condensing fins are of W-shaped design.

[0012] Preferably, the water pump has a liquid extraction pipe fixedly installed at its inlet, the liquid extraction pipe passes through the condenser, and the other end of the liquid extraction pipe is fixedly installed on the water tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This calcium bromide solution concentration device, through the design of a flow-dividing mechanism, forms a stable thin film when the calcium bromide solution flows along the flow-dividing platform into the heat transfer tubes. This facilitates the introduction of hot steam, accelerating the concentration of the calcium bromide solution. The unique trapezoidal design of the flow-dividing platform ensures that the solution is evenly dispersed in the heat transfer tubes, increasing the contact area between the solution and the hot steam. Compared to traditional devices without a flow-dividing structure, this significantly shortens the concentration time, meeting the needs of large-scale production.

[0015] 2. This calcium bromide solution concentration device, through the design of its condensation mechanism, features a tightly fitted condenser fin and condenser tube, significantly expanding the heat exchange area. The steam outlet pipe introduces the high-temperature steam generated in the concentration tower into the evaporator chamber, ensuring full contact between the steam and the condenser fins. The cold water flowing within the condenser tube rapidly absorbs the heat from the steam, causing it to condense quickly into a liquid. Compared to traditional simple condensation structures, this significantly improves condensation efficiency, ensuring that the steam generated during concentration can be processed promptly, maintaining stable operation of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Based on existing technology, the internal structure design of the evaporator in traditional concentration equipment has flaws. The solution flows chaotically within the evaporator, lacking a reasonable diversion and guidance mechanism, preventing the formation of a stable and uniform thin film within the heat transfer tubes. When hot steam is introduced, the contact area between the solution and the steam is limited, resulting in low heat exchange efficiency and significantly prolonged concentration time. In large-scale production scenarios, this inefficient concentration method severely restricts production progress and cannot meet the company's output demands. For example, in the electronic circuit board recycling industry, large quantities of calcium bromide solution require rapid concentration, but traditional equipment struggles to achieve efficient operation. Therefore, this device incorporates a diversion mechanism; please refer to [link / reference]. Figures 1-3 This utility model provides a technical solution: a calcium bromide solution concentration device, including a concentration tower 1, a support leg 2 fixedly installed at the bottom of the concentration tower 1, an evaporator 3 provided on the side of the concentration tower 1, a water pump 4 provided on the side of the evaporator 3, a water tank 6 provided below the evaporator 3, and a condenser 5 provided between the water pump 4 and the water tank 6; the calcium bromide solution concentration device includes a diversion mechanism, a concentration mechanism and a condensation mechanism, including a concentration tower 1, a baffle 2035 fixedly installed inside the upper end of the concentration tower 1, multiple sets of through holes provided on the baffle 2035, and a support rod 2032 fixedly installed on the baffle 2035.

[0024] A mounting plate 2031 is fixedly installed at the top of the support rod 2032, a mounting rod 2033 is fixedly installed at the middle position of the mounting plate 2031, and a flow divider 2034 is fixedly installed at the end of the mounting rod 2033. The flow divider 2034 is a trapezoidal platform.

[0025] The concentration mechanism includes a concentration tower 1, a partition plate 206 is fixedly installed inside the concentration tower 1, and multiple sets of heat transfer tubes 204 are fixedly installed between the partition plate 206 and the baffle 2035. The heat transfer tubes 204 are installed at the through holes on the baffle 2035. A flow distribution platform 2034 is located inside the heat transfer tubes 204, and the bottom diameter of the flow distribution platform 2034 is close to the inner diameter of the heat transfer tubes 204.

[0026] A liquid storage chamber 202 is provided above the baffle 2035. An inlet pipe 201 is fixedly installed at the top of the concentration tower 1. A steam inlet pipe 205 is fixedly installed on the side of the concentration tower 1. The steam inlet pipe 205 is fixedly installed between the baffle 2035 and the partition plate 206. A concentration chamber 207 is provided below the partition plate 206. A steam outlet pipe 209 is fixedly installed at the position of the concentration chamber 207. A condenser pipe 208 is fixedly installed on the partition plate 206. A concentration outlet pipe 210 is fixedly installed at the bottom of the concentration tower 1. A valve 211 is fixedly installed on the concentration outlet pipe 210.

[0027] The calcium bromide solution to be concentrated is injected into the storage chamber 202 through the inlet pipe 201. When the calcium bromide solution is evenly attached to the inner wall of the heat transfer tube 204 by the action of the diverter 203, high-temperature steam is introduced into the concentration tower 1 through the steam inlet pipe 205 to heat the thin film of calcium bromide solution in the heat transfer tube 204, so that the water in the calcium bromide solution vaporizes and is discharged through the steam outlet pipe 209. The water condensed from the high-temperature steam introduced into the concentration tower 1 is transported into the water tank 6 through the condenser pipe 208. Example

[0028] Building upon Example 1, the condensation mechanism of traditional devices is overly simplistic in terms of steam treatment and equipment stability. The small heat exchange area prevents sufficient contact between steam and the cooling medium after steam enters the condensation zone, resulting in slow condensation. This not only affects the timely discharge of steam during concentration but also causes internal pressure fluctuations, seriously threatening the stable operation of the device. If steam cannot condense in time, it may accumulate inside the equipment, leading to a series of safety hazards and reducing the equipment's lifespan. For example, in the concentration units used on offshore oil exploration platforms, the harsh working environment demands extremely high equipment stability, which traditional simple condensation structures cannot meet, frequently resulting in malfunctions and impacting production operations. Therefore, this device incorporates a condensation mechanism. Please refer to [link / reference]. Figures 1-5 This utility model provides a technical solution: a calcium bromide solution concentration device, the condensation mechanism includes a steam outlet pipe 209, the end of the steam outlet pipe 209 is fixedly installed in the evaporator 3, the evaporator 3 is provided with an evaporation chamber 301, and a condensation device 302 is fixedly installed in the evaporation chamber 301.

[0029] The condensing device 302 includes condensing fins 3021, and a first condensing tube 3022 is fixedly installed inside the condensing fins 3021. One end of the first condensing tube 3022 is fixedly installed at the outlet of the water pump 4, and the other end of the first condensing tube 3022 is fixedly installed inside the water tank 6. The evaporator 3 and the water tank 6 are connected by a second condensing tube 304.

[0030] The water pump 4 has a fixed suction pipe 303 installed at its suction port. The suction pipe 303 passes through the condenser 5, and the other end of the suction pipe 303 is fixedly installed on the water tank 6.

[0031] The vaporized steam is transported into the evaporator 3 through the steam outlet pipe 209, where it is condensed by the condensing device 302. The condensed water is then transported back into the water tank 6 through the water tank 6, completing the cycle.
