Description

Technical Field

[0001] This utility model belongs to the field of acid deblocking agents, specifically an energy-saving acid deblocking agent preparation and recycling device. Background Technology

[0002] In many industrial fields such as oil extraction and chemical production, acid dissolution technology is a key means to solve problems such as oil layer blockage and equipment scaling. Acid dissolution agents can react chemically with blockages to dissolve or disperse these substances, thereby restoring the permeability of the oil layer and improving the operating efficiency of equipment. Therefore, the preparation and use of acid dissolution agents play a vital role in ensuring the normal operation of industrial production.

[0003] Traditional acid blockage removers are typically prepared by injecting raw materials into a reaction vessel and stirring and heating them. When used, the remover is directly injected into the pipeline to clear blockages, and then discharged afterward. However, the reaction vessel lacks effective insulation during preparation and cannot directly transfer heat to the raw materials. Consequently, a large amount of heat is lost to the surrounding environment during heating, requiring continuous energy consumption to maintain the required reaction temperature, thus increasing energy consumption. Furthermore, the effective components cannot be efficiently recovered from the used remover, resulting in the waste of significant reusable resources. This not only increases production costs but also places additional pressure on the environment.

[0004] In summary, this invention provides an energy-saving acid deblocking agent preparation and recovery device to solve the above problems. Utility Model Content

[0020] Example 1

[0021] like Figure 1-4 As shown, this is the first embodiment of the present invention. This embodiment provides an energy-saving acid unblocking agent preparation and recovery device, including a preparation unit 1, a recovery unit 2 at the bottom of the preparation unit 1, and an exhaust assembly 3 at the top of the preparation unit 1. The preparation unit 1 includes a reaction tank 11, with an insulation sleeve 12 covering the surface of the reaction tank 11 and a microcontroller 13 on the surface of the insulation sleeve 12. A geared motor 14 is fixedly connected to the top of the reaction tank 11, and the output shaft of the geared motor 14 extends into the inner cavity of the reaction tank 11 and is connected to a stirring shaft 15. A connecting plate 16 is fixedly connected to the upper end of the surface of the stirring shaft 15, and electric heating tubes 17 are fixedly connected to both sides of the bottom of the connecting plate 16. The recovery unit 2 includes a recovery tank 21, with a liquid injection pipe 22 connected to the upper end of one side of the surface of the recovery tank 21. A nanofiltration membrane 23 and an ultrafiltration membrane 24 are respectively provided at the lower and upper ends of the inner cavity of the recovery tank 21, and a liquid outlet pipe 25 is connected to the bottom of the recovery tank 21.

[0022] like Figure 1-4As shown, the rotation of the stirring shaft 15, connecting plate 16, and electric heating tube 17 is driven by the geared motor 14, which allows the raw materials to mix and react inside the reaction tank 11, facilitating the preparation of the acid-dissolving unblocking agent. During the preparation process, the speed of the geared motor 14 can be controlled by the microcontroller 13 to reduce energy waste. Heat is directly transferred to the raw materials through the electric heating tube 17, and the insulation jacket 12 can effectively reduce heat loss inside the reaction tank 11, thereby reducing energy consumption during the heating process, improving energy utilization efficiency, reducing energy consumption, and achieving energy saving. By setting a recovery unit 2 at the bottom of the preparation unit 1, the integrated design of acid-dissolving unblocking agent preparation and recovery is realized, reducing the equipment footprint and material transfer losses, and improving production efficiency. The used acid-dissolving unblocking agent can be effectively separated and purified through the nanofiltration membrane 23 and ultrafiltration membrane 24, improving the recovery rate of effective components and reducing production costs.

[0023] Example 2

[0024] Reference Figure 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0025] In this embodiment, the top of the injection pipe 22 is provided with a round cover, and the surface of the outlet pipe 25 is provided with a valve. The nanofiltration membrane 23 and the ultrafiltration membrane 24 are connected by a vertical rod. The surface of the recovery tank 21 is fixedly connected with a support base 212. The bottom of the reaction tank 11 extends into the inner cavity of the recovery tank 21 and is threadedly connected to the inner cavity of the recovery tank 21. The lower end of the inner cavity of the recovery tank 21 is fixedly connected with a limiting ring 211, and the bottom of the nanofiltration membrane 23 is in contact with the top of the limiting ring 211.

[0026] The output terminal of the microcontroller 13 is connected to the input terminal of the geared motor 14 and the heating tube 17 respectively. The top of the reaction vessel 11 is connected to the feed pipe 112, the lower end of the surface of the reaction vessel 11 is connected to the drain pipe 111, and the surface of the drain pipe 111 is connected to a valve.

[0027] like Figure 1-3 As shown, the limiting ring 211 supports the ultrafiltration membrane 23 and nanofiltration membrane 24, preventing them from shifting or shaking under the impact of liquid flow. The feed pipe 112 facilitates the addition of various raw materials required for preparing the acid dissolving agent into the reaction tank 11. The drain pipe 111 is used to discharge the prepared acid dissolving agent from the reaction tank 11. The injection pipe 22 provides a channel for the used acid dissolving agent to enter the recovery tank 21. The round cover on the top of the recovery tank prevents external impurities and dust from entering the recovery tank 21. The outlet pipe 25 is used to discharge the recovered acid dissolving agent. The support base 212 provides stable support for the recovery tank 21. The recovery tank 21 is threadedly connected to the reaction tank 11, facilitating disassembly and allowing the ultrafiltration membrane 23 and nanofiltration membrane 24 inside the recovery tank 21 to be removed and cleaned.

[0028] Example 3

[0029] Reference Figure 1 and 4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0030] In this embodiment, the exhaust assembly 3 includes an exhaust pipe 31, which is connected to the reaction vessel 11. A connecting ring 32 is provided at the top of the exhaust pipe 31, and an activated carbon adsorption mesh 33 is fixedly connected to the inner cavity of the connecting ring 32.

[0031] A threaded ring 321 is fixedly connected to the bottom of the connecting ring 32. The bottom of the threaded ring 321 extends into the inner cavity of the exhaust pipe 31 and is threadedly connected to the inner cavity of the exhaust pipe 31. The connecting ring 32, the exhaust pipe 31 and the threaded ring 321 are connected.

[0032] like Figure 1 and 4 As shown, the exhaust pipe 31 provides an exhaust channel for the waste gas generated in the reaction tank 11. The activated carbon adsorption net 33 has a strong adsorption capacity and can effectively adsorb the harmful gases generated during the reaction process, reduce the pollution of the waste gas to the environment, and protect the health of the operators. The threaded connection between the activated carbon adsorption net 33 and the exhaust pipe 31 via the screw ring 321 makes it easy to disassemble and install, and facilitates the replacement and maintenance of the activated carbon adsorption net 33.

[0033] In use, the raw materials are first added to the reaction vessel 11 through the feed pipe 112, and the speed of the geared motor 14 and the heating temperature of the electric heating tube 17 are set by the microcontroller 13. Then, the geared motor 14 and the electric heating tube 17 are started to stir and heat the raw materials, thus preparing the acid-dissolving agent. When gas is generated during the preparation process, it is discharged through the exhaust pipe 31. When the gas passes through the activated carbon adsorption net 33, the activated carbon adsorption net 33 adsorbs harmful substances in the gas, thus preventing direct gas emission and pollution to the external environment. After preparation is complete, the liquid is discharged through the drain pipe 111. The prepared acid dissolution agent is discharged through the valve. When the used acid dissolution agent is to be recycled, the round cap on the injection pipe 22 is opened first to inject the used acid dissolution agent into the recycling tank 21. The acid dissolution agent passes through the nanofiltration membrane 23 and the ultrafiltration membrane 24 in the recycling tank 21. The nanofiltration membrane 23 can intercept large molecular impurities and allow small molecular effective components to pass through, achieving preliminary separation. The ultrafiltration membrane 24 can further separate effective components of different molecular weights, improving separation efficiency and purity. Finally, the recycled acid dissolution agent can be collected by opening the valve on the outlet pipe 25 for reuse.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.

[0035] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention.
