Description

Technical Field

[0001] This utility model belongs to the technical field of chemical cleaning equipment, and relates to a mobile reaction vessel cleaning device. Background Technology

[0002] In chemical synthesis, the same reaction vessel is often used to produce different varieties and batches of products. Incomplete cleaning of the reaction vessel can lead to cross-contamination and affect product quality.

[0003] Currently, reflux cleaning is commonly used for reactor cleaning. This method consumes large amounts of solvent and generates significant amounts of waste liquid, which is detrimental to environmental protection. Reflux cleaning also easily creates blind spots, requiring workers to enter the reactor for cleaning, which poses risks due to working in confined spaces. Furthermore, most existing cleaning equipment is fixed to the reactor, making it difficult to quickly disassemble and adapt to other reactors. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a cleaning device that can be used in various reaction vessels and is easily movable.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A portable reactor cleaning device includes: a portable cleaning water tank, a diaphragm pump, and a spraying device. The cleaning water tank is provided with a water outlet, a water return outlet, and an exhaust outlet. The spraying device consists of a spray pipe and a spray ball. After the spraying device is connected to the reactor's manhole, the spray ball is placed inside the reactor. The reactor's discharge port is connected to the water return outlet. The water outlet and a nitrogen delivery device are respectively connected to the diaphragm pump, which pumps water and nitrogen into the spraying device.

[0007] Furthermore, wheels are installed below the cleaning water tank to enable the cleaning device to be moved.

[0008] Furthermore, both the cleaning water tank and the spray device are made of corrosion-resistant materials.

[0009] Choose the appropriate anti-corrosion material based on the corrosiveness of the cleaning fluid, with stainless steel being the preferred material.

[0010] Furthermore, the diaphragm pump is connected to the water outlet, nitrogen delivery device, and spraying device via flexible hoses, and the reactor outlet is connected to the return water outlet via flexible hoses.

[0011] Furthermore, the connections between the diaphragm pump and the outlet, nitrogen delivery device, and spray device, as well as the connection between the reactor outlet and the return water outlet, are all made using detachable fixed pipeline connections.

[0012] Furthermore, the spraying device is connected to the manhole of the reactor via clamps and chucks.

[0013] Furthermore, the spray pipe and the spray ball at the end are connected by clamps.

[0014] Furthermore, the spraying device can be customized by replacing the spray pipes and spray balls according to the size of the reactor and the size of the reactor's manhole. Changing the spray pipes and spray balls allows for better compatibility of the cleaning device with different reactors.

[0015] Furthermore, nitrogen-driven diaphragm pumps deliver cleaning fluid to the spraying device, causing the spray balls to rotate.

[0016] Furthermore, the exhaust port is connected to the exhaust gas absorption system.

[0017] This invention's cleaning device integrates a wheeled cleaning water tank, a diaphragm pump, and a detachable spray system to achieve overall mobility. This solves problems such as the cleaning device's inability to adapt to other reaction vessels, difficulty in quick disassembly, and incomplete cleaning, while also avoiding the operational risks associated with manual tank cleaning.

[0022] The present invention will now be described through specific embodiments. Unless otherwise specified, the technical means used in this invention are all methods known to those skilled in the art. Furthermore, the embodiments should be understood as illustrative, not limiting, of the scope of the invention; the essence and scope of the invention are defined only by the claims. For those skilled in the art, various changes or modifications to these embodiments, without departing from the essence and scope of the invention, also fall within the protection scope of this invention. Example 1

[0023] like Figure 1As shown, a movable reactor cleaning device includes a movable cleaning water tank 1, a diaphragm pump 2, and a spraying device 3. The cleaning water tank 1 is equipped with an outlet 5, a return water inlet 6, and an exhaust outlet 7. The spraying device 3 consists of a spray pipe 12 and a spray ball 10 at the end. After the spraying device 3 is connected to the reactor manhole 9, the spray ball 10 is placed inside the reactor. The reactor outlet 8 is connected to the return water inlet 6, and the exhaust outlet 7 is connected to the tail gas absorption system. The outlet 5 and the nitrogen delivery device 11 are respectively connected to the diaphragm pump 2. The cleaning solution in the cleaning water tank 1 is delivered to the spray pipe 12 by the nitrogen gas delivered by the outlet 5 and the nitrogen gas delivery device 11 through the diaphragm pump 2. Under the action of nitrogen gas pressure, the spray ball 10 rotates, and the cleaning solution is sprayed into the reactor along the spray pipe 12 through the rotating spray ball 10. After cleaning is completed, the reactor outlet 8 is opened and the generated wastewater flows back to the cleaning water tank 1 through the return water outlet 6. The toxic and harmful gases generated after cleaning are treated by the tail gas absorption system connected to the exhaust port 7. The treated wastewater is then subjected to environmental protection treatment.

[0024] The cleaning water tank 1 and the diaphragm pump 2 can be moved as a unit or separately, and all of the above components are connected by hoses. Example 2

The cleaning water tank 1 is made of corrosion-resistant material, and wheels are installed at the bottom of the cleaning water tank 1 for mobility. The spray device 3 is connected to the reactor manhole 9 via clamps 13 and chucks 14. The spray pipe 12 is connected to the spray ball 10 via clamps 13. Other components are connected by quick-disassembly fixed pipelines. Other structures are the same as in Embodiment 1. Example 3
