Non-clogging penetrating mixing cyclone sleeve reactor

Abstract

The invention discloses a non-clogging penetrating mixed cyclone double-tube-reactor. The double-tube-reactor comprises a shell assembly, a plurality of reaction units, a plurality of connecting pieces, a main material inlet pipe and a main material outlet pipe, wherein the shell assembly defines a cavity; the plurality of reaction units are arranged in the cavity at intervals; each reaction unitcomprises an outer pipe, an inner pipe and a reinforcing part; one end of each outer pipe is provided with a first feed nozzle; one end of each inner pipe is provided with a second feed nozzle; a partof each inner pipe is arranged in the corresponding outer pipe, and the other end is open; an annular cavity is formed between each outer pipe and a part being inserted into the outer pipe of the corresponding inner pipe; the reinforcing parts are arranged on the part being inserted into the outer pipe of the inner pipe; each connecting piece makes two adjacent reaction units communicate with each other; the main material inlet pipe is communicated with the reaction units; the main material outlet pipe is communicated with the reaction units. By adopting the non-clogging penetrating mixed cyclone double-tube-reactor according to the embodiment of the invention, material mixing is enhanced, material clogging can be prevented, the reaction process parameters are increased, the reaction efficiency is increased, the reaction time is reduced, and safe, fault-free, leakage-free, long-period and efficient running is realized.

Description

technical field [0001] The invention relates to the technical field of reaction equipment, in particular to a non-blocking through-mixing swirl sleeve reactor. Background technique [0002] At present, more and more attention has been paid to the treatment of sludge and sewage. Among them, the wet oxidation process (WetAir Oxidation, referred to as WAO) of sewage sludge refers to the use of oxidants and catalysts (such as oxygen in the air, Ozone, hydrogen peroxide and other oxidants, Cu-based, Mn-based, Fe-based and composite catalysts) oxidize organic matter in sewage sludge into carbon dioxide and water, thereby achieving the purpose of removing pollutants.

AI Technical Summary

Problems solved by technology

[0003] In the horizontal reactor (tank) of the related art, 4-6 continuously stirred step-down tanks are arranged in the reactor, and each tank is provided with a stirring and aeration device, which is not only limited in pressure (generally is about 2MPa), the process parameters (temperature, pressure) are low, it is difficult to achieve higher pressure and temperature process parameters, such as subcritical and supercritical water oxidation processes, resulting in low reaction efficiency and long reaction time

[0004] Moreover, due to the installation of multiple mechanical stirring devices, the stirring is prone to leakage and failure, and may even cause safety accidents. The stirring in the tank is not sufficient and uniform, which affects the reaction efficiency and reaction time, increases energy consumption, and at the same time, many A continuous stirring step downcomer pool has low-velocity zones, vortex dead zones, etc. Due to the high viscosity and cohesiveness of the sludge, it seriously affects the overall reaction efficiency, prolongs the reaction time, and seriously affects the reaction product. Quality, larger structure size and larger floor area, higher equipment investment

[0005] In addition, some sundries (such as hair, plastic bags, woven bags, branches, leaves, etc.) are not thoroughly filtered and remain in the sludge, especially fibrous sundries can easily block the tubular, tank, and tower reactors, resulting in Tubular, tank and tower reactors are difficult to operate normally
