Description

Technical Field

[0001] This utility model relates to the field of dehydrogenation, specifically to a dehydrogenation device. Background Technology

[0002] In chemical engineering, petroleum refining, and organic synthesis, dehydrogenation is an important chemical reaction process widely used in the preparation of compounds such as olefins and aromatics. Traditional dehydrogenation units typically suffer from low reaction efficiency, incomplete product separation, and unstable temperature control, resulting in high overall energy consumption, complex equipment, and high operating and maintenance costs.

[0003] A Chinese patent proposes a refining dehydrogenation tower (application number: CN202222558175.7), comprising a tank body with an outlet pipe connected to the upper end. A feed pipe is fixedly connected to the side of the tank body. A preheating pipe is installed on the outer wall of the feed pipe near the tank body. Pressure sensors are sequentially arranged on the preheating pipe away from the tank body. Each pressure sensor includes a sensing housing, which is fixedly connected to the feed pipe. A sliding valve is slidably connected to the feed pipe near the sensing housing. A piston is fixedly connected to the upper end of the sliding valve, and a spring is fixedly connected to the piston away from the sliding valve. This invention achieves automatic control of the tank pressure without affecting the internal temperature of the tank by using a sensing housing connected to the outlet pipe at the upper part of the housing cavity. The spring then pushes the sliding valve to cut off the feed pipe, causing the tank to lose gas supply. After continuous discharge, the feed pipe is restored.

[0004] Most existing dehydrogenation devices employ a single reaction chamber structure, lacking effective means to control the catalytic reaction environment, particularly in the efficient simultaneous processing of gaseous and liquid products. Furthermore, the low integration of the temperature control system negatively impacts the stability and safety of the reaction process.

[0005] Therefore, there is a need to provide a new type of dehydrogenation device with a reasonable structure, precise temperature control, high reaction efficiency, and thorough product separation to meet the requirements of high efficiency, energy saving, and environmental protection in industrial production. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a dehydrogenation device.

The other end of the processing tank has a discharge head with an exhaust port and a liquid discharge port on its exterior. A catalytic inlet is provided through the exterior of the discharge head, and the other end of the catalytic inlet is connected to a transition pipe. The other end of the transition pipe is connected to a liquid discharge pipe.

[0009] Optionally, the connector is fixedly connected to the intake control pipe, and a processing valve is provided on the outside of the connector.

The transition pipe and the drain pipe are located inside the processing tank, and the temperature circulation chamber is connected to the temperature inlet and the temperature outlet, respectively.

[0014] Optionally, the drain pipe is threaded to the transition pipe, and protruding holes are uniformly formed on the outside of the drain pipe.

[0015] The beneficial effects achieved by this utility model are as follows:

[0016] This invention, by setting up an inlet control pipe, can precisely control the amount and flow rate of materials entering, ensuring a stable and controllable reaction process. Simultaneously, a catalytic zone is set up inside the processing tank, allowing the materials to react fully under suitable conditions, improving dehydrogenation efficiency. The gaseous products after the catalytic reaction are discharged through the exhaust port, while the liquid products are separated and output through the liquid drain port, achieving efficient separation of the gas and liquid phases, avoiding cross-contamination, and improving product purity. By setting up temperature inlets and outlets and connecting them to an external temperature-controlled liquid circulation system, a constant reaction temperature within the processing chamber is effectively maintained, ensuring the continuity and stability of the dehydrogenation reaction and improving overall reaction efficiency.

The transition pipe 801 and the drain pipe 803 are located inside the processing tank 1. The temperature circulation chamber 102 is connected to the temperature inlet 2 and the temperature outlet 3, respectively.

[0033] Optionally, a spiral plugging blade 802 is provided on the outside of the transition tube 801, and the spiral plugging blade 802 contacts the inner wall of the processing chamber 101.

[0034] Specifically, the spiral plugging blade 802 can increase the reaction distance, facilitating subsequent catalytic dehydrogenation of the feedstock.

[0035] Optionally, the drain pipe 803 is threadedly connected to the transition pipe 801, and protruding holes are evenly provided on the outside of the drain pipe 803.
