Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to an activation system for activated carbon and resin. Background Technology

[0002] In chemical plant distillation units, activated carbon and resins remove impurities and harmful substances from raw materials or products through adsorption and exchange, which is of great significance for improving product purity and quality. In the polysilicon production process, the activation devices for activated carbon and resins have a profound impact, as the activation effect directly relates to the removal rate of boron, phosphorus, and metallic impurities, thus affecting product purity.

[0003] In existing technologies, activation devices typically use a nitrogen pipeline to blow nitrogen from the bottom of the device for activation. This method has significant drawbacks: it cannot quickly resolve high-temperature or high-heat issues, which can easily lead to safety accidents; moreover, when the device is fed, since the interior is filled with activated carbon or resin, if the material entering the device contains large particles of impurities, these impurities will adhere to the inner wall of the device or the activated carbon and resin, adversely affecting the device's lifespan, activation effect, and adsorption effect. Utility Model Content

[0004] The present invention aims to solve the problems mentioned in the background art by providing an activation system for activated carbon and resin to address the aforementioned technical problems.

[0005] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: an activation system for activated carbon and resin, comprising an activation device and a filter, wherein the bottom of the activation device is connected to a pneumatic pressure relief valve via a drain pipeline; a feed valve B, a drain valve b, and a filter are sequentially connected to one side of the bottom of the activation device via a feed pipeline; a feed valve A and a feed inlet are connected to one side of the filter via a feed pipeline; and a drain valve a, a first pressure reducing valve, and a nitrogen port are sequentially connected to the bottom of the filter via an air inlet pipeline.

[0006] Specifically, the top of the activation device is connected to a pneumatic regulating valve and an exhaust outlet via an exhaust pipe; the diameter of the exhaust pipe is DN40.

[0007] Specifically, the upper part of one side of the activation device is connected to a second pressure reducing valve and a nitrogen port via a nitrogen pipeline.

[0008] Specifically, the outer walls of the feed pipeline, drain pipeline, feed pipeline and air intake pipeline are coated with an anti-corrosion coating made of epoxy resin.

[0009] Compared with the prior art, this utility model has the following advantages: The addition of a nitrogen pipeline at the top of this device effectively prevents dangerous situations such as high temperature, high heat, and high pressure during activation. The introduction of nitrogen allows for timely control of the reaction rate, protecting the resin and activated carbon inside the device from damage and ensuring maximum activation efficiency. The filter is connected to the nitrogen pipeline at the bottom and also to the feed pipeline, ensuring smooth flow of material into the activation device. This reduces the adverse effects of larger impurities in the material, improving the device's lifespan, activation efficiency, and adsorption capacity. The addition of a top nitrogen pipeline and a bottom filter structurally enhances the device's efficiency and safety, providing more reliable support for industrial production.

[0012] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention: An activation system for activated carbon and resin includes an activation device 1 and a filter 2. The bottom of the activation device 1 is connected to a pneumatic pressure relief valve 10 through a drain line for discharging waste liquid or other by-products generated during the activation process. This effectively solves the problem of blowing materials from top to bottom to the drain line when high temperature and high heat occur during the activation process, thereby reducing the temperature and pressure inside the device, protecting the activated carbon and resin from damage, and preventing the occurrence of explosion accidents due to high temperature and high heat. Simultaneously, hot nitrogen can be alternately blown from the top and bottom during drying to accelerate the process and ensure thorough drying. The bottom of one side of the activation device 1 is connected in sequence to a feed valve B7, a drain valve b6, and a filter 2 via pipelines. The filter 2 is connected to a feed valve A3 and a feed inlet via a feed pipeline, ensuring smooth material flow. The feed pipeline is equipped with a filter 2 to prevent impurities from entering the activation device, contaminating the activated carbon and resin, and extending their service life. The bottom of the filter 2 is connected in sequence to a drain valve a5, a first pressure reducing valve 4, and a nitrogen inlet via an air inlet pipeline.

[0013] Furthermore, the top of the activation device 1 is connected to a pneumatic regulating valve 9 and an exhaust outlet via an exhaust pipe; the diameter of the exhaust pipe is DN40, which is an increase from the original DN25 to DN40, and it is equipped with a pneumatic regulating valve.

[0014] Furthermore, the upper part of one side of the activation device 1 is connected to a second pressure reducing valve 8 and a nitrogen port via a nitrogen pipeline, which effectively protects the resin and activated carbon inside the device from damage and also allows for better control of the activation process, ensuring the maximum activation effect.

[0015] Furthermore, the outer walls of the feed pipeline, drain pipeline, feed pipeline and air inlet pipeline are coated with an anti-corrosion coating made of epoxy resin.

[0016] During activation, the first step is to open feed valve A3 to begin feeding silicon tetrachloride into the activation device. Then, open nitrogen drain valve a5 at the bottom of filter 2 to introduce hot nitrogen into the system. Under the heating effect of the hot nitrogen, the material undergoes a phase change, transforming from a liquid phase to a gas phase. At this point, open feed valve B7 to allow the gaseous material to enter the activation device. Here, activated carbon and resin play a crucial role, adsorbing these gaseous materials to achieve a good activation effect. However, some problems may arise during activation, such as high temperature, excessive heat, and excessive pressure within the device. To address these issues, the nitrogen pipeline at the top of the device, by introducing cooler nitrogen, effectively controls the reaction rate within the device, preventing the resin from overheating due to excessively rapid reaction.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
