Description

Technical Field

[0001] This invention relates to the field of alcohol waste liquid recycling technology, and specifically to a vaporization device based on the recycling and reuse of alcohol-containing waste liquid. Background Technology

[0002] Alcohol-containing waste liquids are widely generated in many industrial sectors such as chemical, pharmaceutical, electronics, and energy. Their direct discharge not only causes serious environmental pollution but also leads to the waste of a large amount of high-value alcohol resources. With increasingly stringent environmental regulations and continuously rising resource prices, the recycling and reuse of alcohol-containing waste liquids has changed from an "optional" to a "mandatory" choice for enterprises.

[0003] There are various ways to recycle and reuse alcohol-containing waste liquid, which can be mainly divided into several categories such as distillation, membrane separation, and ion exchange. Among them, distillation is the most widely used and technologically mature core method. Its principle is very simple: it utilizes the difference in boiling points of the components (alcohols and other substances) in the waste liquid. By heating, the lower boiling point alcohols are preferentially converted into vapor, and then condensed into liquid, thus achieving the separation and collection of alcohol substances.

[0004] Taking methanol-based waste liquid as an example, the waste liquid is first pretreated, for instance, by using a filter to remove suspended solids, residues, and other impurities. Then, the waste liquid is preheated before entering a distillation column for further heating, causing the methanol to vaporize and rise. The collected gaseous methanol is then condensed in a condenser to obtain liquid methanol. The heating temperature of the distillation column is generally controlled slightly above the boiling point of methanol (64.7 degrees Celsius) to preferentially vaporize the methanol. However, even at temperatures far below the atmospheric boiling point of water (100 degrees Celsius), water molecules still gain sufficient energy to continue evaporating. Therefore, the final collected steam includes not only methanol vapor but also water vapor, forming a mixture of both. This directly leads to two main problems: firstly, it reduces the purity of the recovered methanol, increasing the difficulty and cost of subsequent purification; secondly, the presence of water vapor in the mixed steam consumes the processing capacity of the condenser and distillation column, reducing the system's effective recovery efficiency.

[0005] Based on the above, the present invention proposes a vaporization device based on the recycling and reuse of alcohol-containing waste liquid. Summary of the Invention

[0006] To address the negative impacts of water vapor in the collected mixed steam mentioned above, this invention provides a vaporization device based on the recycling and reuse of alcohol-containing waste liquid, which can minimize the water vapor content in the mixed steam.

[0007] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows.

[0008] A vaporization device based on the recycling and reuse of alcohol-containing waste liquid includes a frame on which a vacuum pump, a water pump and vaporization components are installed.

[0009] The vaporization assembly includes a vaporization tank with its centerline arranged horizontally and capable of rotating around the centerline. A heating element is provided on the outside of the vaporization tank, and blades are provided on the inner wall of the vaporization tank. Multiple blades are arranged in an array along the circumference of the vaporization tank.

[0010] The vaporization tank contains both gas and liquid pipelines, both of which are coaxial with the vaporization tank. The liquid pipeline provides a path for injecting waste liquid into the vaporization tank and for discharging the remaining waste liquid after vaporization. The gas pipeline provides a path for collecting the vapor discharged during the vaporization process.

[0011] As a further improvement and optimization of the present invention, each end of the vaporization tank extends a connecting shaft, the connecting shaft is coaxial with the vaporization tank, the connecting shaft is movably connected to the frame, and the connecting shaft is connected to the motor mounted on the frame through a power transmission component.

[0012] As a further improvement and optimization of the present invention, the blade is in the shape of extending along the axis of the vaporizer and continuously bending.

[0013] As a further improvement and optimization of the present invention, both ends of the gas pipeline extend out of the vaporization tank and are connected to the frame. One end of the gas pipeline is connected to a suction branch pipe and a valve a is provided at the end of the suction branch pipe. The other end of the gas pipeline is connected to an inlet branch pipe and a valve b is provided at the end of the inlet branch pipe. The outer circular surface of the gas pipeline is also provided with air holes, and multiple air holes are arranged in an array along the axis of the gas pipeline.

[0014] As a further improvement and optimization of the present invention, the liquid pipeline is located inside the gas pipeline, both ends of the liquid pipeline extend out of the gas pipeline and are connected to the frame, and a valve c is provided at one end of the liquid pipeline and a valve d is provided at the other end.

[0015] A baffle is installed inside the liquid pipeline, which divides the liquid pipeline into two non-connected sections, namely the liquid inlet section and the liquid outlet section. The liquid inlet section is connected to the lowest point of the outer circular surface of the liquid inlet section, and the lower end of the liquid inlet section passes through the gas pipeline and is close to the lowest point of the inner wall of the vaporization tank. The liquid outlet section is connected to the lowest point of the outer circular surface of the liquid outlet section, and the lower end of the liquid outlet section passes through the gas pipeline and is close to the lowest point of the inner wall of the vaporization tank.

[0016] As a further improvement and optimization of the present invention, the input end of the vacuum pump is connected to valve a, the output end of the vacuum pump is provided with a collection pipe, and the input end of the water pump is connected to valve d.

[0017] As a further improvement and optimization of the present invention, the outer circular surface of the gas pipeline is provided with an arc plate by means of a bracket. The arc plate is bent downward and coaxially located above the gas pipeline.

[0018] As a further improvement and optimization of the present invention, initially, the vaporization tank is in a negative pressure state;

[0019] The end of the collection pipe is equipped with a three-way pipe C, and each of the remaining two ports of the three-way pipe C is equipped with a solenoid valve.

[0020] As a further improvement and optimization of the present invention, two vaporization components are provided.

[0021] As a further improvement and optimization of the present invention, the input end of the vacuum pump is connected to the valve a of the two vaporization components through a three-way pipe a;

[0022] The water pump input is connected to the valves d of the two vaporization components via a three-way pipe b.

[0023] Compared with the prior art, the advantages of this invention are as follows:

[0024] Technical advantage 1: The technical advantage of the vaporization tank being initially under negative pressure is that it can prevent the liquid level of the waste liquid injected into the vaporization tank from exceeding the set value, thus ensuring the smooth operation of vaporization.

[0025] Technical effect 2: During the vaporization process, the vaporization tank rotates along with the blades, thereby agitating the waste liquid inside the vaporization tank and keeping the temperature of each part of the waste liquid consistent, thus providing better conditions for the evaporation of alcohols.

[0026] Technical Effect 3: Furthermore, the blades are continuously bent, and during the rotation of the vaporization tank, they scoop up and pour out the waste liquid. The poured-out waste liquid eventually falls onto the arc plate and flows downward along the arc plate, forming a continuously flowing water curtain at both ends of the arc plate. On the one hand, the waste liquid can directly enter the gas pipeline through the vent, thus preventing waste liquid leakage. On the other hand, a small portion of the mixed steam of gaseous alcohols and water vapor is located inside the water curtain and directly enters the gas pipeline through the vent. However, most of the mixed steam is located outside the water curtain, so it needs to pass through the water curtain to enter the gas pipeline through the vent. Since the water curtain itself is also composed of waste liquid, the heat of the water vapor will be transferred to the water curtain during the process of the mixed steam passing through the water curtain, causing the alcohols in the water curtain to absorb heat and evaporate, while the water vapor releases heat and condenses. In this way, the alcohols in the waste liquid are evaporated and extracted, and the purpose of capturing water vapor is achieved, reducing the water vapor content in the mixed steam.

[0027] Technical benefit 4: By cooperating with the two vaporization components, the purpose of alternating use can be achieved, thereby achieving continuous and uninterrupted operation and higher efficiency. Attached Figure Description

[0037] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0038] Example 1

[0039] Reference Figures 1-7 A vaporization device based on the recycling and reuse of alcohol-containing waste liquid includes a frame 100, on which a vacuum pump 101, a water pump 102, a motor 103, and a vaporization assembly 200 are mounted. In use:

[0040] Alcohol-containing waste liquid is injected into vaporization component 200 and heated by vaporization component 200. The resulting mixed steam is drawn away by vacuum pump 101, and the remaining water is drawn away by water pump 102.

[0041] The mixed steam includes alcohol vapor and water vapor. One of the core aspects of this application is to minimize the proportion of water vapor in the mixed steam, thereby addressing a series of negative effects caused by excessive water vapor as mentioned in the background art.

[0042] Reference Figures 4-7 The vaporization assembly 200 includes a vaporization tank 201 with its centerline arranged horizontally. Each end of the vaporization tank 201 has a connecting shaft extending from it. The connecting shaft is coaxial with the vaporization tank 201 and is movably connected to the frame 100, for example, through a bearing. The connecting shaft is connected to the motor 103 through a power transmission component 1031. The power transmission component 1031 can be implemented using existing power transmission route technology, which will not be elaborated here. The motor 103 can drive the vaporization tank 201 to rotate.

[0043] The vaporization tank 201 is equipped with a heating element 202 on its exterior. The heating element 202 can be implemented using existing electric heating technology, which will not be described in detail.

[0044] The inner wall of the vaporization tank 201 is provided with blades 203. Multiple blades 203 are arranged in an array along the circumference of the vaporization tank 201. Furthermore, the blades 203 are in a continuous bent shape along the axis of the vaporization tank 201. That is to say, when the vaporization tank 201 rotates and rotates with the blades 203: on the one hand, the blades 203 have a stirring effect on the waste liquid in the vaporization tank 201, improving the heating uniformity; on the other hand, the blades 203 have a scooping-pouring action on the waste liquid in the vaporization tank 201. This scooping-pouring action can not only further improve the stirring effect, but also cooperate with the arc plate 207 to form a liquid curtain. The technical effect of the liquid curtain will be described in detail later.

[0045] The vaporization tank 201 also contains a gas pipe 204 and a liquid pipe 205, both of which are coaxial with the vaporization tank 201.

[0046] Both ends of the gas pipeline 204 extend out of the vaporization tank 201 and are connected to the frame 100. One end of the gas pipeline 204 is connected to a suction branch pipe 2041 and a valve a 2042 is installed at the end of the suction branch pipe 2041. The other end of the gas pipeline 204 is connected to an inlet branch pipe 2043 and a valve b 2044 is installed at the end of the inlet branch pipe 2043. The outer circular surface of the gas pipeline 204 is also provided with air holes 2045, and multiple air holes 2045 are arranged in an array along the axis of the gas pipeline 204.

[0047] The liquid pipeline 205 is located inside the gas pipeline 204. Both ends of the liquid pipeline 205 extend out of the gas pipeline 204 and are connected to the frame 100. One end of the liquid pipeline 205 is equipped with a valve c2054 and the other end is equipped with a valve d2055.

[0048] A partition 2051 is installed inside the liquid pipeline 205, which divides the liquid pipeline 205 into two non-connected sections, namely the liquid inlet section and the liquid outlet section. The liquid inlet section is connected to the lowest point of the outer circular surface of the liquid inlet section, and the lower end of the liquid inlet section 2052 passes through the gas pipeline 204 and is close to the lowest point of the inner wall of the vaporization tank 201. The liquid outlet section is connected to the lowest point of the outer circular surface of the liquid outlet section, and the lower end of the liquid outlet section 2053 passes through the gas pipeline 204 and is close to the lowest point of the inner wall of the vaporization tank 201.

[0049] An arc plate 207 is provided on the outer circular surface of the gas pipeline 204 via a bracket 206. Furthermore, the arc plate 207 is bent downwards and coaxially located above the gas pipeline 204.

[0050] The input end of vacuum pump 101 is connected to valve a2042, and the output end of vacuum pump 101 is provided with a collection pipe 1012. The input end of water pump 102 is connected to valve d2055.

[0051] The working process of Example 1:

[0052] Initially, the vaporization tank 201 is under negative pressure;

[0053] Step 1: Connect valve C2054 to the storage tank containing the waste liquid. The storage tank is not shown in the diagram.

[0054] When valve C2054 is opened, under negative pressure, the waste liquid enters the vaporization tank 201 through valve C2054, liquid pipe 205, and inlet pipe 2052 in sequence. When the liquid level in the vaporization tank 201 approaches the vent 2045, the liquid inlet is stopped and valve C2054 is closed. Preferably, the distance between the liquid level and the lowest point of the outer circular surface of the vaporization tank 201 is two-thirds of the radius of the vaporization tank 201.

[0055] The technical advantage of vaporizing tank 201 being initially under negative pressure is that it can prevent the liquid level of the waste liquid injected into vaporizing tank 201 from exceeding the set value.

[0056] Step 2: The vacuum pump 101, motor 103, and heating element 202 are started;

[0057] The motor 103 works in conjunction with the heating element 202 to achieve the evaporation and extraction of alcohols from the waste liquid. Specifically, the heating element 202 keeps the internal temperature of the vaporization tank 201 near the boiling point of the alcohols, while the motor 103 drives the vaporization tank 201 to rotate. Together, they achieve the purpose of evaporating the alcohols into a gaseous state.

[0058] At the same time, the vacuum pump 101 is started, drawing gaseous alcohols from the vaporization tank 201. The gaseous alcohols leave the vaporization tank 201 through the vent 2045, gas pipe 204, suction branch pipe 2041, and the opened valve a2042 and collection pipe 1012, and are collected and stored.

[0059] Its technological advantages lie in:

[0060] 1. The vaporizer 201 rotates together with the blades 203, thereby agitating the waste liquid inside the vaporizer 201, keeping the temperature of each part of the waste liquid consistent, and providing better basic conditions for the evaporation of alcohols.

[0061] 2. Furthermore, the blades 203 are continuously bent, and during the rotation of the vaporizer 201, they perform a scooping-and-pouring action on the waste liquid. The poured-out waste liquid eventually falls onto the arc plate 207 and flows downward along the arc plate 207, forming a continuously flowing water curtain at both ends of the arc plate 207. On the one hand, this allows the waste liquid to directly enter the gas pipe 204 through the vent 2045, thus preventing waste liquid leakage. On the other hand, a small portion of the mixed vapor of gaseous alcohols and water vapor, located inside the water curtain, directly passes through the vent 204. 5. The gas enters the gas pipe 204, but most of the mixed steam is located outside the water curtain. Therefore, it needs to pass through the water curtain to enter the gas pipe 204 through the vent 2045. Since the water curtain itself is also composed of waste liquid, the heat of the water vapor will be transferred to the water curtain during the process of the mixed steam passing through the water curtain, causing the alcohol in the water curtain to absorb heat and evaporate, while the water vapor releases heat and condenses. In this way, the alcohol in the waste liquid is evaporated and extracted, and the purpose of capturing water vapor is achieved, reducing the water vapor content in the mixed steam.

[0062] It is important to note that one of the core aspects of this case is to maximize the reduction of water vapor content in the mixed steam, rather than to remove water vapor 100%.

[0063] Step 3: After the preset time, the evaporation, extraction and collection of alcohol substances are completed. Vacuum pump 101, motor 103 and heating element 202 stop running. Valve b2044 and valve d2055 are opened. Water pump 102 starts. The remaining liquid in vaporization tank 201 is discharged sequentially through drain pipe 2053, liquid pipeline 205 and valve d2055. At the same time, outside air enters vaporization tank 201 through valve b2044, air inlet pipe 2043, gas pipeline 204 and air hole 2045, providing basic conditions for the smooth discharge of the remaining liquid.

[0064] Step 4: After the remaining liquid is discharged, valves b2044 and d2055 are closed, and vacuum pump 101 is started to draw out the gas in vaporization tank 201, making vaporization tank 201 under negative pressure. At this time, vaporization component 200 returns to its initial state and can start the next round of evaporation, extraction and collection of alcohols in waste liquid.

[0065] It should be noted that since not only gaseous alcohols but also air are discharged from the collection pipe 1012, a three-way pipe c can be installed at the end of the collection pipe 1012. A solenoid valve is installed at each of the remaining two ports of the three-way pipe c. Two discharge paths are constructed through the remaining two ports of the three-way pipe c, allowing gaseous alcohols and air to be discharged separately without interference.

[0066] Example 2

[0067] A vaporization device based on the recycling and reuse of alcohol-containing waste liquid, wherein two vaporization components 200 are provided.

[0068] Reference Figures 1-3 The input end of the vacuum pump 101 is connected to the valve a2042 of the two vaporization components 200 through a three-way pipe a1011.

[0069] The input end of the water pump 102 is connected to the valve d2055 of the two vaporization components 200 through a three-way pipe b1021.

[0070] In this way, the two vaporization components 200 can be used alternately to achieve continuous and uninterrupted operation, resulting in higher efficiency.

[0071] In summary, the technical advantages of this application are as follows:

[0072] Technical advantage 1: The technical advantage of the vaporization tank being initially under negative pressure is that it can prevent the liquid level of the waste liquid injected into the vaporization tank from exceeding the set value, thus ensuring the smooth operation of vaporization.

[0073] Technical effect 2: During the vaporization process, the vaporization tank rotates along with the blades, thereby agitating the waste liquid inside the vaporization tank and keeping the temperature of each part of the waste liquid consistent, thus providing better conditions for the evaporation of alcohols.

[0074] Technical Effect 3: Furthermore, the blades are continuously bent, and during the rotation of the vaporization tank, they scoop up and pour out the waste liquid. The poured-out waste liquid eventually falls onto the arc plate and flows downward along the arc plate, forming a continuously flowing water curtain at both ends of the arc plate. On the one hand, the waste liquid can directly enter the gas pipeline through the vent, thus preventing waste liquid leakage. On the other hand, a small portion of the mixed steam of gaseous alcohols and water vapor is located inside the water curtain and directly enters the gas pipeline through the vent. However, most of the mixed steam is located outside the water curtain, so it needs to pass through the water curtain to enter the gas pipeline through the vent. Since the water curtain itself is also composed of waste liquid, the heat of the water vapor will be transferred to the water curtain during the process of the mixed steam passing through the water curtain, causing the alcohols in the water curtain to absorb heat and evaporate, while the water vapor releases heat and condenses. In this way, the alcohols in the waste liquid are evaporated and extracted, and the purpose of capturing water vapor is achieved, reducing the water vapor content in the mixed steam.

[0075] Technical benefit 4: By cooperating with the two vaporization components, the purpose of alternating use can be achieved, thereby achieving continuous and uninterrupted operation and higher efficiency.
