Non-clogging penetrating mixing swirl tubular reactor

Abstract

The invention discloses a blockage-free penetration and mixing cyclone pipe type reactor. The blockage-free penetration and mixing cyclone pipe type reactor comprises a shell, a supporting piece, a plurality of blockage-free penetration and mixing cyclone pipe type reaction units, a main reaction material inlet and output connecting pipe and an auxiliary reaction material inlet and outlet connecting pipe. Each blockage-free penetration and mixing cyclone pipe type reaction unit comprises a reaction unit pipe and an inlaid welding inclined reinforcing piece arranged in the reaction unit pipe, areinforcing piece chamfer and / or a reinforcing piece fillet is formed on at least part of the edge of each inlaid welding inclined reinforcing piece in the extension direction to prevent sundries inreaction materials from being hung and clamped on the inlaid welding inclined reinforcing piece. According to the blockage-free penetration and mixing cyclone pipe type reactor, main reaction materials and added materials can be automatically stirred and fully mixed, uniform and efficient reaction is implemented, blockage of the reaction materials is prevented effectively, and long-period, safe, reliable and efficient running of the reactor can be realized.

Description

technical field [0001] The invention relates to the technical field of sewage or sludge treatment, in particular to a non-blocking penetrating mixing swirl tube reactor. Background technique [0002] In related technologies, the wet oxidation process is used for urban sewage sludge treatment, especially the Wetox process of partial wet oxidation, which is an advanced process that is clean and can maximize the utilization of resources. The Wetox process of partial wet oxidation: a horizontal reactor (tank) is used, and 4-6 continuously stirred step downflow tanks are arranged in the reactor, and each tank is also equipped with a stirring and aeration device. [0003] However, the above-mentioned horizontal reactor also has some disadvantages: first, the pressure is limited (generally about 2MPa), the process parameters (temperature, pressure) are low, and it is difficult to achieve higher pressure and temperature process parameters, such as sub- The critical and supercritica...

Problems solved by technology

[0003] However, the above-mentioned horizontal reactor also has some disadvantages: First, the pressure is limited (generally about 2MPa), the process parameters (temperature, pressure) are low, and it is difficult to achieve higher pressure and temperature process parameters, such as sub- The critical and supercritical water oxidation process makes the reaction efficiency low and the reaction time too long; second, multiple mechanical agitators are set up, which are prone to leakage, failure and even safety accidents, and the agitation of the tank is also insufficient and insufficient. Equal, affect the reaction efficiency and reaction time, and the energy consumption also increases; Third, there are also low-speed zones, vortex dead zones, etc. The high viscosity and cohesiveness of the sludge seriously affect the overall reaction efficiency and prolong the reaction time, and seriously affect the quality of the reaction product. Due to the above reasons, etc., the reaction efficiency is low and the reaction time is long; Fourth, the reaction efficiency is low and the reaction time is long, which also makes the structure size larger and the floor area larger, and the equipment investment is higher

[0004] In addition, although the debris filtration process is set in the sludge pretreatment process, it is still inevitable that some debris remains in the sludge, such as hair, plastic bags, woven bags, branches, leaves, etc. These debris, especially fiber Such debris can easily block conventional tubular, tank, and tower reactors, making it difficult for conventional tubular, tank, and tower reactors to operate normally
