Description

Technical Field

[0001] This invention relates to the field of water-cooled wall technology, and more particularly to a high-efficiency water-cooled wall for reactors. Background Technology

[0002] Reactors in existing technology can be classified as follows: Isothermal reactors: Ideal reactors where the temperature of the reactants is constant throughout the system. Reactors with minimal heat effect, sufficient heat exchange between the reactants and the heat carrier, or significant heat feedback within the reactor (such as a vigorously stirred batch reactor) can be approximated as isothermal reactors. Adiabatic reactors: Ideal reactors where there is no heat exchange between the reaction zone and the environment. Large industrial reactors without heat exchange devices in the reaction zone, where heat exchange with the outside is negligible, can be approximated as adiabatic reactors. Non-isothermal and non-adiabatic reactors: Reactors that exchange heat with the outside and experience heat feedback within the reactor, but do not achieve isothermal conditions, such as tubular fixed-bed reactors. Heat exchange can occur in the reaction zone, such as in a stirred tank reactor with jacketed heat exchange, or within the reaction zone, such as in a multi-stage reactor with interstage heat exchange.

[0003] Water-cooled walls consist of numerous tubes arranged along the inner walls of the reactor. Their function is to absorb heat radiated from the flue gas and protect the reactor. Currently, in reactors where water-cooled walls are used, heat cannot be transferred quickly when the reaction is vigorous and there are issues such as uneven heat absorption, uneven heat exchange, and uneven heat distribution. This can seriously affect the normal operation of the reactor reaction. Summary of the Invention

[0004] To address the shortcomings of the existing technology, the present invention provides a high-efficiency water-cooled wall for reactors, which is used in reactors with vigorous reactions, uneven heat distribution, and a need for rapid and uniform absorption of reaction heat.

[0006] In some embodiments, the water-cooled wall support frame includes an inner water-cooled wall partition, an outer water-cooled wall partition, and a plurality of water-cooled wall spacers, wherein the inner water-cooled wall partition, the outer water-cooled wall partition, and the plurality of water-cooled wall spacers constitute a plurality of the spacer regions.

[0007] In some embodiments, the outer baffle of the water-cooled wall is fixed to the inner wall of the reactor, the inner baffle of the water-cooled wall is longitudinally attached to and wrapped around the water-cooled wall tube, and the two ends of the inner baffle of the water-cooled wall are fixed to the outer baffle of the water-cooled wall.

[0008] The plurality of water-cooled wall partitions are respectively arranged on both sides of each water-cooled wall tube. The two ends of the water-cooled wall partitions are fixed to the inner partition and the outer partition of the water-cooled wall to maintain the distance between them and the water-cooled wall tube.

[0009] In some embodiments, the closely arranged various types of water-cooled wall tubes include: water-cooled wall inlet tubes, water-cooled wall outlet tubes, horizontal swivel tubes, vertical swivel tubes, turning tubes, and interference bypass tubes arranged in close contact with each other.

[0010] In some embodiments, the water-cooled wall inlet pipe is provided with a water-cooled wall inlet, and the water-cooled wall outlet pipe is provided with a water-cooled wall outlet.

[0011] In some embodiments, the water-cooled wall inlet and water-cooled wall outlet can be arranged in any orientation according to process requirements.

[0012] In some embodiments, cooling water flows through the water-cooled wall inlet, passes through the entire water-cooled wall, and then flows out from the water-cooled wall outlet, completing the entire heat exchange process.

[0013] Compared with the prior art, the advantages of the technical solution of the present invention are as follows:

[0014] The reactor provided by this invention has a compact high-efficiency water-cooled wall structure that covers the entire inner wall. The inlet and outlet pipes can be set at any position according to process requirements, which is beneficial to the arrangement of reactor pipes and facilitates piping connection, effectively solving the problem of easy interference in pipe piping.

[0015] The water-cooled wall support structure skeleton of the reactor provided by this invention can ensure accurate positioning of the water-cooled wall pipe spacing and firmly fix the water-cooled wall to the inner wall of the reactor.

[0016] The reactor provided by this invention uses a high-efficiency water-cooled wall with various loop pipelines to achieve uniform mixing of pipelines in different heat sections, effectively reducing local heat concentration and achieving efficient heat conduction. Attached Figure Description
