Technical Field
[0001] The utility model relates to the technical field of petrochemical industry, in particular to an anti-clogging dechlorinator system. Background Art
[0002] In the production process of petrochemical products, chlorides are contained in the raw materials themselves, and chlorides are also introduced during the processing and production process. However, excessive chlorides will bring some negative effects, such as corrosion to reforming unit equipment, pipeline blockage, and even catalyst poisoning to workers. Therefore, the removal of chlorides is of great significance to ensure the normal production of enterprises.
[0003] The desulfurization process of chloride mainly uses a dechlorinating agent to react in a dechlorination tank. The main use of dechlorinating agents for dechlorination is that the active components of the dechlorinating agent will undergo an acid-base neutralization reaction with HCl to generate stable metal chlorides which are then fixed, thereby achieving the purpose of removing HCl.
[0004] However, in the prior art, the upstream raw materials contain a large amount of ash and colloid during the reaction of the dechlorination tank, which is easy to block the gaps between the catalysts at the top during operation, causing pressure to rise, affecting operation safety, and thus causing the entire tank of dechlorination agent to be scrapped, resulting in economic losses. This in turn increases the company's equipment usage fees, labor costs, solid waste treatment fees, etc. Utility Model Content
[0005] In view of the above-mentioned defects, the utility model provides a blockage-resistant dechlorinator system which can timely avoid the blockage section when blockage occurs, thereby ensuring continuous operation of the device and reducing losses and risks, thereby achieving good effect and low risk, long dechlorination agent service life and low dechlorination cost.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a blockage-proof dechlorinator system, comprising a dechlorinator feed main pipeline, a dechlorinator side feed main pipeline, and a discharge pipeline, wherein the dechlorinator feed main pipeline is connected to the feed end at the top of the dechlorinator, the dechlorinator feed end is provided with a dechlorinator feed main pipeline through valve, the dechlorinator feed main pipeline is also connected to the dechlorinator side feed main pipeline, and the upper, middle, and tail portions of the dechlorinator side feed main pipeline are sequentially connected to the upper side of the dechlorinator. The feed pipe, the feed pipe in the middle of the dechlorination tank, and the feed pipe at the bottom of the dechlorination tank are connected to the upper, middle and lower parts of the dechlorination tank respectively. Valves are provided on the outer sides of the connection points between the feed pipe in the upper side of the dechlorination tank, the feed pipe in the middle of the dechlorination tank, and the feed pipe at the bottom of the dechlorination tank and the dechlorination tank. The bottom discharge end of the dechlorination tank is connected to the discharge pipeline, and a discharge pipe through valve is provided at the bottom discharge end of the dechlorination tank.
[0007] As a further improvement of the utility model, the dechlorination tank feed main pipeline through valve and the discharge pipeline through valve are both solenoid valves.
[0008] As a further improvement of the utility model, the dechlorination tank is filled with a reformed oil liquid phase dechlorination agent.
[0009] As a further improvement of the utility model, a pressure sensor is installed on the pipe wall of the dechlorination tank feed main pipe.
[0010] As a further improvement of the present invention, a pressure sensor is installed on the pipe wall of the discharge pipeline.
[0011] As a further improvement of the utility model, pressure sensors are provided at the connection points between the upper feed pipe of the dechlorination tank, the middle feed pipe of the dechlorination tank, the lower feed pipe of the dechlorination tank and the dechlorination tank.
[0012] Beneficial effects of the utility model:
[0013] 1. By setting up multiple pipelines, it is ensured that when the upper part of the pipeline is blocked, the dechlorinating agent in the lower layer of the pipeline can still be used effectively, and the chlorine capacity of the dechlorinating agent in the dechlorinating tank is fully utilized, thereby ensuring that the service life of the dechlorinating agent is extended as much as possible.
[0014] 2. Different pipelines and valves on the pipelines are relatively independent and can be opened individually or together at will. Users can use them flexibly according to their needs, avoiding the current situation of blockage of the dechlorinator at the line inlet and insufficient use of the dechlorinator. It can effectively improve the dechlorination effect and dechlorination efficiency, reduce the cost of catalyst use, labor costs, solid waste treatment costs, etc., and ensure maximum corporate benefits.

[0022] like Figures 1 to 5 The anti-clogging dechlorinator system shown in the figure comprises a dechlorinating tank feed main pipeline 1 and a dechlorinating tank side feed main pipeline 2. One end of the dechlorinating tank feed main pipeline 1 is connected to the material supply end, and the other end of the dechlorinating tank feed main pipeline 1 is connected to the feed end at the top of the dechlorinating tank 6.

The dechlorinating tank 6 is filled with a dechlorinating agent, and the dechlorinating agent is mainly a reforming oil liquid phase dechlorinating agent, which is generally a molecular sieve and a calcium zinc type. The discharge end of the dechlorinating tank 6 is connected to one end of the discharge pipeline 7, and a pressure sensor is provided on the pipeline wall at the connection between the discharge pipeline 7 and the discharge end. The discharge end at the bottom of the dechlorinating tank 6 is provided with a discharge pipeline through valve 70, and the other end of the discharge pipeline 7 is connected to the discharge collection place.
[0023] As a further illustration of this example, the dechlorination tank feed main pipeline through valve 10 and the discharge pipeline through valve 70 are both solenoid valves.
[0024] The dechlorination tank feed main pipeline 1 is also connected to the dechlorination tank side feed main pipeline 2. The upper part of the dechlorination tank side feed main pipeline 2 is connected to the dechlorination tank 6 through the dechlorination tank upper side feed pipeline 3.

[0029] As a further illustration of this example, after the colloid is blocked, the pressure drop will increase, and the pressure sensor is used to detect whether it is blocked by the pressure drop. The blockage position is generally blocked from top to bottom, and the pressure drop will gradually increase.
[0030] The working principle and use process of this utility model:
[0031] 1. In normal working state: the upper through valve 30, the middle through valve 40 and the lower through valve 50 are all in the closed state, the main pipeline through valve 10 and the discharge pipeline through valve 70 are in the open state, and the undechlorinated material enters the top feed end of the dechlorination tank 6 from the material supply end through the dechlorination tank feed main pipeline 1. After the undechlorinated material reacts with the dechlorination agent in the dechlorination tank 6 for dechlorination, it is discharged from the discharge end at the bottom of the dechlorination tank 6 through the discharge pipeline 7 to the discharge collection point.
[0032] 2. When the pressure drop of the pressure sensor at the dechlorination tank feed main pipeline 1 increases and the top pipeline of the dechlorination tank 6 is blocked: the main pipeline through valve 10, the middle through valve 40, and the lower through valve 50 are all in a closed state, and the upper through valve 30 and the discharge pipeline through valve 70 are in an open state. The undechlorinated material first enters the dechlorination tank side feed main pipeline 2 from the material supply end through the dechlorination tank feed main pipeline 1, and then directly enters the upper part of the dechlorination tank 6 from the upper side feed pipeline 3 of the dechlorination tank. After the undechlorinated material undergoes dechlorination reaction with the dechlorination agent in the dechlorination tank 6, it is discharged from the discharge end at the bottom of the dechlorination tank 6 through the discharge pipeline 7 to the discharge collection point.
[0033] 3. When the pressure drop of the pressure sensor at the upper feed pipe 3 of the dechlorination tank increases and the upper pipeline of the dechlorination tank 6 is blocked: the main pipeline through valve 10, the upper through valve 30, and the lower through valve 50 are all in a closed state, and the middle through valve 40 and the discharge pipeline through valve 70 are in an open state. The undechlorinated material first enters the dechlorination tank side feed main pipe 2 from the material supply end through the dechlorination tank feed main pipe 1, and then directly enters the middle part of the dechlorination tank 6 from the dechlorination tank middle side feed pipe 4. After the undechlorinated material undergoes dechlorination reaction with the dechlorinating agent in the dechlorination tank 6, it is discharged from the discharge end at the bottom of the dechlorination tank 6 through the discharge pipeline 7 to the discharge collection point.
[0034] 4. When the pressure drop of the pressure sensor at the upper feed pipe 4 of the dechlorination tank increases and the middle pipeline of the dechlorination tank 6 is blocked: the main pipeline through valve 10, the upper through valve 30, and the middle through valve 40 are all in a closed state, and the lower through valve 50 and the discharge pipe through valve 70 are in an open state. The undechlorinated material first enters the dechlorination tank side feed main pipe 2 from the material supply end through the dechlorination tank feed main pipe 1, and then directly enters the lower part of the dechlorination tank 6 from the lower feed pipe 5 of the dechlorination tank. After the undechlorinated material undergoes dechlorination reaction with the dechlorination agent in the dechlorination tank 6, it is discharged from the discharge end at the bottom of the dechlorination tank 6 through the discharge pipeline 7 to the discharge collection point.
[0035] After the switch, the blocked part is not processed temporarily, and after the dechlorination reaction of the dechlorinating agent is complete, the dechlorinating agent in the dechlorinating tank 6 is uniformly unloaded.
[0036] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above implementation measures. All technical solutions under the idea of the utility model belong to the protection scope of the utility model.
