Description

Technical Field

[0001] This utility model relates to the technical field of triethylamine recovery equipment, specifically a glass-lined reactor based on triethylamine treatment. Background Technology

[0002] Triethylamine recovery reactors are typically used in chemical production for the recovery and reuse of triethylamine. These reactors allow for the distillation and recovery of triethylamine. The reactors generally include heating, cooling, recovery, and control systems to ensure the efficient separation and recovery of triethylamine from the mixture.

[0003] Existing reactors have some shortcomings. In actual use, the gas is cooled by a spiral cooling pipe inside the reactor. However, the complex structure of the spiral cooling pipe makes it easy for scale to form on the surface of the pipe after long-term use. Cleaning the scale is very inconvenient and reduces its practicality. Utility Model Content

[0004] To address the shortcomings of existing technologies, a glass-lined reactor based on triethylamine treatment is disclosed, comprising a reactor body, an inlet pipe and an outlet pipe provided on the reactor body, and a cooling pipe provided inside the reactor body.

[0005] Preferably, the cooling pipe includes a horizontal section and a vertical section, the vertical section being embedded in the left and right side walls of the vessel body, and the horizontal section being connected to the vertical section.

[0006] Preferably, a descaling structure is provided on the horizontal section. The descaling structure includes a scraper ring slidably disposed on the horizontal section, a slide rod connected to the scraper ring, the slide rod slidingly penetrating the side wall of the vessel body, and the outside of the slide rod being connected to the vessel body via a first electric push rod.

[0007] Preferably, a pair of pipes pass through the slide rod, a cavity is formed inside the scraper ring, one end of the pipe is located inside the cavity, and a nozzle is installed at the inner end of the pipe inside the cavity. The cavity extends outward and has a through hole.

[0008] Preferably, a second electric push rod is installed on the upper wall of the scraper ring, and a sealing plate is installed on the second electric push rod, the sealing plate being slidably connected to the side wall of the scraper ring.

[0009] Preferably, a deflector is installed on the air intake pipe via a connecting rod.

[0010] Preferably, a drain pipe is provided on the lower wall of the vessel.

[0011] This utility model has the following beneficial effects: The utility model has a reasonable structure and novel design. In use, gas is injected into the reactor body, and a cooling pipe is connected to a cooling box to inject cold water into the cooling pipe for cooling the gas. The water continuously circulates to ensure the cooling effect. When descaling the horizontal section, the descaling agent is first sprayed onto the horizontal section through a nozzle. The pump power is gradually increased, causing the descaling agent to be sprayed onto the horizontal section in a parabolic shape. Under the action of gravity, the descaling agent flows along the arc surface of the horizontal section, gradually covering it for easy descaling. A first electric push rod drives a sliding rod to move, which in turn drives a scraper ring to move. The scraper ring moves across the horizontal section, removing the scale. After the scraper ring finishes cleaning, it moves back to the left. During this back-movement, the pump is activated to spray water from the nozzle onto the horizontal section to clean the descaling agent. Attached Figure Description
