Description

Technical Field

[0001] This utility model belongs to the field of triethanolamine collection, specifically, it relates to a triethanolamine product collection device. Background Technology

[0002] Triethanolamine is typically produced by reacting ethylene oxide with ammonia under high temperature and pressure. The reaction products are a mixture of monoethanolamine, diethanolamine, and triethanolamine, which requires a series of complex distillation separation processes to obtain high-purity triethanolamine. This distilled, qualified liquid triethanolamine is collected during the production process using a collection device.

[0003] However, existing triethanolamine product collection devices have some shortcomings in actual use. The existing devices may not be precise enough in terms of temperature control. The state and properties of triethanolamine will change at different temperatures, and poor temperature control may affect the quality of the product and the collection efficiency.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a triethanolamine product collection device, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A triethanolamine product collection device includes: two product tanks, each product tank is connected to a raw material tank pipe, the raw material tank pipe is equipped with a transfer pump, and a product filling tank pipe is provided below the product tanks;

[0008] An outer half-pipe is provided on the outer periphery of the product tank. The two ends of the outer half-pipe are respectively connected to the hot water main pipe and the self-heating hot water main pipe. A flow meter and a regulating valve are provided on the hot water main pipe.

[0009] Optionally, the product tank is connected to a self-purging nitrogen main pipe, and the self-purging nitrogen main pipe is connected to a self-nitrogen sealing nitrogen main pipe.

[0010] Optionally, the product tank is connected to a main exhaust pipe.

[0011] Optionally, a self-compressed air pipe and a waste liquid main pipe are connected to the bottom of the product tank.

[0012] Optionally, a product buffer tank pipe is connected to the product filling tank pipe.

[0013] Optionally, a sampling manual control box is connected to the product filling tank pipe, and both the product filling tank pipe and the sampling manual control box are connected to a self-purging nitrogen main pipe.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] By setting the outer half-pipes on the outer periphery of the two product tanks, the temperature of the triethanolamine product in the product tanks can be effectively controlled. When the product needs to maintain a certain temperature to maintain its good fluidity and stability, hot water can flow into the outer half-pipes through the hot water main pipe. During the process of flowing around the product tank, the heat is transferred to the triethanolamine in the product tank. The hot water main pipe can then discharge the hot water after heat exchange, forming a circulating hot water supply system.

[0016] The flow meter installed on the hot water main can monitor the flow rate of hot water in real time. Operators can precisely adjust the flow rate of hot water by adjusting the regulating valve according to the actual temperature of triethanolamine in the product tank, thereby achieving precise temperature control. This temperature control method can not only ensure the quality of triethanolamine products, but also avoid problems such as product performance degradation caused by excessively high or low temperatures.

[0017] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0023] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Please see Figure 1-2 As shown, this embodiment provides a triethanolamine product collection device, including: two product tanks 1, a raw material tank pipe 2 connected to the product tank 1, a transfer tank pump 3 installed on the raw material tank pipe 2, and a product filling tank pipe 4 installed below the product tank 1;

[0026] The outer periphery of product tank 1 is provided with an outer half pipe 15, and the two ends of the outer half pipe 15 are respectively connected to the hot water main pipe 8 and the self-heating hot water main pipe 9. The hot water main pipe 8 is equipped with a flow meter and a regulating valve.

[0027] Among them, the capacity of the two product tanks 1 is 4m³. 3 To ensure product specifications, the product tank is nitrogen-sealed, and the cylinder is made of 304 stainless steel lined with fluoropolymer. The fluoropolymer is from an imported brand, which reduces the risk of metal ion precipitation and ensures product purity. The product tank is equipped with an external coil half-pipe, through which hot water from the client is supplied. The hot water flow rate is controlled by an interlock between a flow meter and a regulating valve to maintain the product temperature inside the tank. Finally, qualified products are pumped to the product filling unit via a blower pump. The blower pump outlet is designed with a sampling port. Based on the sampling and analysis results, it is determined whether the product is sent to the product filling unit or returned to the raw material tank for re-purification. The product tank is designed with pressure monitoring, liquid level monitoring, temperature monitoring, nitrogen port, exhaust port, vacuum port, cleaning port, drain port, and discharge port.

[0028] By using the outer half-pipes 15 installed on the outer periphery of the two product tanks 1, the temperature of the triethanolamine product in the product tank 1 can be effectively controlled. When the product needs to maintain a certain temperature to maintain its good fluidity and stability, hot water can flow into the outer half-pipes 15 through the hot water main pipe 8. During the flow around the product tank 1, the heat is transferred to the triethanolamine in the product tank 1. The hot water main pipe 9 can then discharge the hot water after heat exchange, forming a circulating hot water supply system.

[0029] The flow meter installed on the hot water main pipe 8 can monitor the flow rate of hot water in real time. Operators can precisely adjust the flow rate of hot water by adjusting the regulating valve according to the actual temperature of triethanolamine in product tank 1, thereby achieving precise temperature control. This temperature control method can not only ensure the quality of triethanolamine products, but also avoid problems such as product performance degradation caused by excessively high or low temperatures.

[0030] like Figure 2 As shown, in this embodiment, the product tank 1 is connected to a self-purging nitrogen main pipe 5, and the self-purging nitrogen main pipe 5 is connected to a self-nitrogen sealing nitrogen main pipe 6.

[0031] The function of the self-purging nitrogen main pipe 5 is to periodically purge the product tank 1 during the operation of the device to prevent impurities or other substances from accumulating in the tank and affecting the purity of the triethanolamine product. The self-nitrogen sealing nitrogen main pipe 6 provides nitrogen sealing protection for the product tank 1. When the triethanolamine in the product tank 1 comes into contact with air, it may undergo chemical reactions such as oxidation, which may affect the product quality. By filling the product tank 1 with nitrogen through the self-nitrogen sealing nitrogen main pipe 6, a nitrogen protective film is formed on the product surface, isolating the product from the air and effectively avoiding oxidation and other problems.

[0032] Both the self-purging nitrogen main pipe 5 and the self-sealing nitrogen main pipe 6 are equipped with corresponding valves and pressure sensors. The valves can control the amount of nitrogen entering the pipeline as needed, while the pressure sensors can monitor the nitrogen pressure in the pipeline in real time. Operators can adjust the opening of the valves to precisely control the flow rate and pressure of nitrogen according to the actual situation in the product tank 1, so as to ensure that the purging and nitrogen sealing effects reach the best state.

[0033] like Figure 2 As shown, the product tank 1 in this embodiment is connected to the exhaust gas main pipe 7.

[0034] The main function of the exhaust gas main pipe 7 is to collect and treat the exhaust gas generated in the product tank 1. During the storage of triethanolamine products, some volatile gases may be generated. If these exhaust gases are directly discharged into the atmosphere, they will not only cause environmental pollution, but may also pose certain safety hazards. The exhaust gas main pipe 7 is connected to the product tank 1 and can promptly draw out the exhaust gas in the tank.

[0035] like Figure 2 As shown, in this embodiment, the product tank 1 is connected to a self-compressed air pipe 10 and a waste liquid main pipe 11.

[0036] The function of the self-compressed air pipe 10 is to introduce compressed air into the product tank 1 when necessary to assist in the transportation of the product or to clean the inside of the tank. When the product needs to be transported from the product tank 1 to other equipment, the compressed air can provide a certain pressure to speed up the outflow of the product and improve the transportation efficiency.

[0037] The waste liquid drain pipe 11 is used to discharge the waste liquid in the product tank 1. During the production and storage of triethanolamine products, some waste liquid will be generated. This waste liquid may contain impurities, unqualified products, or sewage generated from cleaning the tank. The waste liquid drain pipe 11 is connected to the bottom of the product tank 1, which can promptly draw out this waste liquid and prevent the waste liquid from accumulating in the tank and affecting product quality.

[0038] like Figure 2 As shown, in this embodiment, a product buffer tank 12 is connected to the product filling tank 4.

[0039] The product buffer tank 12 plays an important role in buffering and regulating. During the process of transporting triethanolamine from product tank 1 through product filling tank 4, the transport may be unstable due to various factors, such as pressure fluctuations and flow rate changes. The product buffer tank 12 can temporarily introduce some product into the product buffer tank. When the transport pressure is too high or the flow rate is too high, the excess product will enter the product buffer tank through the product buffer tank 12 for storage, so as to avoid causing too much impact on the subsequent filling tank and ensure the smooth progress of the filling process.

[0040] Meanwhile, when the product flow rate in the product filling tank 4 is insufficient, the product stored in the product buffer tank can flow back to the product filling tank 4 through the product buffer tank 12, which can replenish the product and maintain the continuity of product transportation.

[0041] like Figure 2 As shown, in this embodiment, a sampling manual control box 14 is connected to the product filling tank pipe 4, and a self-purging nitrogen main pipe 13 is connected to both the product filling tank pipe 4 and the sampling manual control box 14.

[0042] During the process of transporting triethanolamine products through the product filling tank pipe 4, impurities or residual products may adhere to the inner wall of the self-purging nitrogen main pipe 13. Over time, this may affect the quality of the product and the transport performance of the pipeline. The self-purging nitrogen main pipe 13 can periodically introduce nitrogen into the product filling tank pipe 4 and the sampling manual control box 14, and use the pressure of nitrogen to blow out the impurities and residual products in the pipeline, thereby cleaning the pipeline.

[0043] For the sampling manual control box 14, during the sampling process, some product may remain in the manual control box, which will not only affect the accuracy of subsequent sampling, but may also pose certain safety hazards to the operators. The nitrogen gas introduced by the self-purging nitrogen main pipe 13 can remove the residual product in the manual control box, ensuring the cleanliness and safety of the sampling environment.

[0044] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
