Description

Technical Field

[0001] This utility model relates to the field of chemical raw material processing technology, specifically to an evaporator for dehydrating chemical raw materials. Background Technology

[0002] A chemical raw material dehydration evaporator is a device specifically designed for the chemical industry to dehydrate chemical raw materials. Its core working principle is to use heat to convert the water in the liquid raw material into steam, thereby achieving dehydration, concentration, or drying.

[0003] A search revealed that patent CN202221982036.0 discloses an evaporator for dehydrating chemical raw materials. While this device heats the evaporation tank using an electric heating plate, causing the saturated solution inside to boil and partially vaporize and crystallize, and utilizes a steam condensation mechanism to reduce harmful substances released into the air, and a collection mechanism to collect and clean the condensed liquid, and a cooling water circulation mechanism to circulate and cool the cooling water in the cooling pool, the device cannot operate continuously, severely limiting its production efficiency. In the chemical industry, which requires large-scale, high-efficiency production, this intermittent production method is clearly unacceptable. Furthermore, intermittent production necessitates frequent equipment start-ups and shutdowns, which not only increases operational complexity but may also lead to accelerated equipment wear and tear, thereby increasing maintenance and replacement costs. Simultaneously, due to low production efficiency, achieving the same output may require longer production times and greater energy consumption, further increasing production costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an evaporator for dehydrating chemical raw materials, thus solving the problems mentioned in the background art.

[0005] The solution of this utility model to the above-mentioned technical problems is as follows:

[0006] An evaporator for dehydrating chemical raw materials includes a shell, a heating head is installed at one end of the shell, and a base is installed at the bottom end of the heating head and the shell.

[0007] A condenser head is installed at the end of the outer shell away from the heating head. Both the heating head and the condenser head are equipped with heat exchange coils. The heating head and the condenser head are respectively equipped with a heating medium outlet head, a heating medium inlet head, a condenser medium outlet head, and a condenser medium inlet head. Both the heating head and the condenser head are equipped with a second partition. The interior of the heating head and the condenser head are respectively divided into two cavities by the second partition. The two cavities are respectively connected to the two ends of the first inlet head.

[0008] The outer shell has a first partition inside, and the outer shell is divided into a heating chamber and a condensation chamber by the first partition.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the two cavities inside the heating head are respectively connected to the heating medium outlet head and the heating medium inlet head.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] This design allows the heating medium to flow through two cavities within the heating head, thereby increasing the contact area between the heating medium and the heating head body. A larger contact area means more heat can be effectively transferred to the heating head body, thus heating the chemical raw materials. By optimizing the flow path and velocity of the heating medium, heat exchange efficiency can be further improved, ensuring that the chemical raw materials are heated uniformly and rapidly within the heating chamber. The two-cavity design within the heating head helps achieve a uniform distribution of the heating medium. When the heating medium enters the heating head from the inlet, it flows through two independent cavities, where it is thoroughly mixed and diffused. This uniform distribution of the heating medium ensures that the temperature remains consistent throughout the heating head body, thus avoiding localized overheating or underheating of the chemical raw materials during the heating process.

[0013] Furthermore, the two cavities of the condenser head are respectively connected to the condenser medium outlet head and the condenser medium inlet head.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The two cavities of the condenser head are connected to the condenser outlet and inlet respectively, ensuring sufficient flow of the condenser medium within the condenser head and adequate heat exchange with the water vapor in the condensation chamber. This design increases the contact area between the condenser medium and water vapor, thereby improving condensation efficiency. Uniform distribution of the condenser medium within the condenser head is crucial for ensuring uniform condensation. The two-cavity design allows the condenser medium to flow more evenly through the condenser head, avoiding problems of insufficient or excessive condensation in certain areas. This uniform condensation effect helps maintain product quality and stability.

[0016] Furthermore, the outer casing is provided with a first pressure stabilizing connector and a first inspection port at the top of the heating chamber, and the outer casing is provided with a first liquid inlet and a first discharge pipe at the bottom of the heating chamber.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] The first pressure stabilizing connector ensures stable pressure within the heating chamber. During the dehydration process of chemical raw materials, pressure fluctuations may occur within the heating chamber. The pressure stabilizing connector effectively absorbs and regulates these fluctuations, preventing damage to the equipment from excessively high or low pressure. By maintaining stable pressure within the heating chamber, the first pressure stabilizing connector helps reduce the risk of equipment malfunction during operation. This not only improves equipment reliability but also ensures operator safety. The first inspection port provides operators with a convenient passage for inspecting and repairing components within the heating chamber. This helps to identify and resolve problems promptly, preventing escalation of faults. The first liquid inlet precisely controls the flow rate of the heating medium, ensuring uniform temperature distribution within the heating chamber. This helps improve the dehydration efficiency and quality of chemical raw materials. The first discharge pipe ensures timely discharge of waste liquid generated within the heating chamber, preventing accumulation of waste liquid within the equipment and causing pollution or damage.

[0019] Furthermore, the outer casing is provided with a second inspection port and a second pressure stabilizing connector at the top of the condensation chamber, and the outer casing is provided with a second discharge pipe at the bottom of the condensation chamber.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] The second inspection port, located at the top of the condensing chamber, provides operators with a convenient access for regular inspection, maintenance, and repair of the condensing chamber's interior. This helps to promptly identify and resolve problems, ensuring the condenser's normal operation. Regular maintenance and repairs allow for the timely detection and replacement of worn or damaged components, preventing equipment malfunctions during operation. This contributes to improved equipment reliability and stability. The second pressure stabilizing connector ensures stable pressure within the condensing chamber. During condensation, pressure fluctuations may occur within the chamber, and the pressure stabilizing connector effectively absorbs and regulates these fluctuations, preventing damage from excessively high or low pressure. The second drain pipe, located at the bottom of the condensing chamber, allows for the timely discharge of condensate generated during the condensation process. This helps prevent condensate buildup within the condensing chamber, which could cause blockages or damage to the equipment.

[0022] Furthermore, the outer casing has a first inspection port and a second inspection port on one side surface of the heating chamber and the condensation chamber, respectively.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] The first and second inspection ports are located on one side surface of the heating and condensing chambers, respectively, allowing operators to directly observe the internal operation of the equipment. During operation, abnormalities such as blockages, leaks, and scaling can be detected promptly through these ports, enabling timely intervention. Regular or irregular inspections through these ports allow for the timely identification and resolution of potential problems. This helps prevent problems from escalating, avoids equipment malfunctions during operation, and thus improves equipment reliability.

[0025] This invention provides an evaporator for dehydrating chemical raw materials. It has the following beneficial effects:

[0026] Both the heating head and the condenser head are equipped with heat exchange coils, which greatly improves heat exchange efficiency. The heating medium heats the chemical raw materials through the heat exchange coils in the heating head, causing the moisture in them to evaporate rapidly. Subsequently, the water vapor enters the condensation chamber and exchanges heat with the condensing medium through the heat exchange coils in the condenser head, thereby achieving efficient condensation.

[0027] The heating head and condenser head are internally divided into two cavities by a second partition. These two cavities are connected to the heating medium outlet, heating medium inlet, and condenser outlet and inlet, respectively. This design allows the heating and condenser media to flow along predetermined paths, ensuring effective heat transfer and recovery.

[0028] The interior of the outer shell is divided into a heating chamber and a condensation chamber by a first partition. These two chambers are interconnected but have distinct functions. The heating chamber is used to heat the chemical raw materials, causing the moisture in them to evaporate; while the condensation chamber is used to condense the water vapor, thereby achieving a dehydration effect. This separation design not only improves dehydration efficiency but also facilitates equipment maintenance and repair. Attached Figure Description

[0037] 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.

[0038] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0039] Example 1

[0040] An evaporator for dehydrating chemical raw materials includes a shell 2, a heating head 1 installed at one end of the shell 2, a base 4 installed at the bottom of the heating head 1 and the shell 2, and a condenser head 3 installed at the end of the shell 2 away from the heating head 1. Both the heating head 1 and the condenser head 3 are provided with heat exchange coils 210, and the heating head 1 and the condenser head 3 are respectively provided with a heating medium outlet head 101, a heating medium inlet head 102, a condenser medium outlet head 301, and a condenser medium inlet head 302. Both the heating head 1 and the condenser head 3 are provided with a second partition 303, which divides the interior of the heating head 1 and the condenser head 3 into two cavities. The two cavities are respectively connected to the two ends of a first inlet head 201. The two cavities in the heating head 1 are respectively connected to the heating medium outlet head 101 and the heating medium inlet head 102. This design adopts a dual-chamber heating head 1 structure, which allows the heating medium to flow in two independent cavities, thereby significantly increasing the heat exchange contact area between the heating medium and the heating head 1 body. A larger contact area promotes efficient heat transfer, thereby improving the heating efficiency of chemical raw materials. By optimizing the flow path and velocity of the heating medium, heat exchange efficiency can be further improved, ensuring that the chemical raw materials reach the required temperature uniformly and rapidly within the heating chamber 211. Furthermore, the dual-chamber design facilitates the uniform distribution of the heating medium within the heating head 1. When the heating medium flows in from the inlet, it mixes and diffuses fully in the two independent cavities, ensuring temperature consistency across all parts of the heating head 1 and avoiding localized overheating or underheating. The two cavities of the condensing head 3 are connected to the condensing medium outlet 301 and the condensing medium inlet 302, respectively. The dual-chamber structure of the condensing head 3, connected to both the condensing medium outlet and inlet, ensures sufficient flow of the condensing medium within the condensing head 3 and effective heat exchange with the water vapor in the condensing chamber 214. This design increases the contact area between the condensing medium and water vapor, significantly improving condensation efficiency. Uniform distribution of the condensing medium within the condensing head 3 is crucial for maintaining the uniformity of the condensation effect. The dual-chamber design allows the condensing medium to flow more evenly through the condenser head 3, avoiding problems such as insufficient or excessive condensation in certain areas, thereby ensuring the quality and stability of the product.

[0041] Example 2

[0042] To increase the dehydration efficiency of chemical raw materials, for example, such as Figures 1 to 4As shown, the present invention further includes: a first partition 213 is provided inside the outer casing 2, and the outer casing 2 is divided into a heating chamber 211 and a condensing chamber 214 by the first partition 213. The heating chamber 211 and the condensing chamber 214 are interconnected. After the chemical raw material is heated in the heating chamber 211, the water in the chemical raw material is decomposed into water vapor and flows to the condensing chamber 214 for condensation, thereby achieving the effect of dehydration of the chemical raw material. The outer casing 2 is provided with a first pressure stabilizing connector 202 and a first inspection port 204 at the top of the heating chamber 211, and a first liquid inlet 201 and a first discharge pipe 203 at the bottom of the heating chamber 211. The first pressure stabilizing connector 202 ensures the stability of the pressure inside the heating chamber 211. During the dehydration process of the chemical raw material, pressure fluctuations may occur inside the heating chamber 211, and the pressure stabilizing connector can effectively absorb and regulate these fluctuations, preventing excessively high or low pressures from damaging the equipment. Maintaining stable pressure within the heating chamber 211 helps reduce the risk of equipment malfunctions, improving equipment reliability and operator safety. The first inspection port 204 provides a convenient channel for component inspection and maintenance within the heating chamber 211, facilitating timely detection and resolution of problems and preventing the spread of faults. The first liquid inlet head 201 achieves uniform temperature distribution within the heating chamber 211 by precisely controlling the flow rate of the heating medium, thereby improving the dehydration efficiency and quality of chemical raw materials. The first discharge pipe 203 ensures timely discharge of waste liquid from the heating chamber 211, preventing accumulation and contamination within the equipment. The outer casing 2, located at the top of the condensing chamber 214, has a second inspection port 206 and a second pressure stabilizing connector 209. The outer casing 2, located at the bottom of the condensing chamber 214, has a second discharge pipe 207. The second inspection port 206, located at the top of the condensing chamber 214, provides a convenient channel for regular inspection, maintenance, and repair of the condensing chamber 214. This helps to promptly detect and replace worn or damaged components, preventing equipment malfunctions during operation and thus improving equipment reliability and stability. The second pressure stabilizing connector 209 ensures the stability of the pressure within the condensing chamber 214, effectively absorbing and regulating pressure fluctuations that may occur during condensation, preventing equipment damage. The second discharge pipe 207, located at the bottom of the condensing chamber 214, can promptly discharge condensate generated during condensation, preventing condensate buildup within the condensing chamber 214 that could lead to blockage or damage. The outer casing 2 has a first inspection port 205 and a second inspection port 208 on one side of the heating chamber 211 and the condensing chamber 214, respectively, providing operators with a direct means to observe the internal operation of the equipment. Through these inspection ports, operators can promptly detect abnormalities inside the equipment, such as blockages, leaks, and scaling, and take immediate action. Regular or irregular inspections through these ports can promptly identify and resolve potential problems, preventing escalation and ensuring reliable equipment operation.

[0043] Working principle:

[0044] Chemical raw materials are introduced into the heating chamber 211. The heat exchange coil 210 in the heating head 1 heats the chemical raw materials in the heating chamber 211 through a heating medium (such as steam, hot water, etc.). As the temperature rises, the moisture in the chemical raw materials begins to evaporate, forming water vapor. The water vapor generated by evaporation accumulates in the heating chamber 211 and flows to the condensation chamber 214 due to pressure or temperature differences.

[0045] The heat exchange coil 210 inside the condenser head 3 cools the water vapor in the condenser chamber 214 using a condensing medium (such as cold water or air). As the temperature decreases, the water vapor begins to condense and transform into liquid water. The condensed liquid water is discharged from the equipment through the second drain pipe 207 at the bottom of the condenser chamber 214.

[0046] The heating medium enters the heating head 1 through the heating medium inlet 102, passes through the heat exchange coil 210, and is discharged through the heating medium outlet 101. The condensing medium enters the condensing head 3 through the condensing medium inlet 302, passes through the heat exchange coil 210, and is discharged through the condensing medium outlet 301.

[0047] The pressure regulating connectors on the equipment (such as the first pressure regulating connector 202 and the second pressure regulating connector 209) are used to ensure that the equipment maintains a stable pressure environment during operation. By adjusting parameters such as the flow rate and temperature of the heating and condensing media, precise control of the evaporation and condensation processes can be achieved.

[0048] The access ports (such as the first access port 204 and the second access port 206) and inspection ports (such as the first inspection port 205 and the second inspection port 208) on the equipment allow operators to inspect, maintain and repair the interior of the equipment.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
