Abstract

The invention discloses a continuous organic solid waste pyrohydrolysis treatment system and method. The continuous organic solid waste pyrohydrolysis treatment system comprises a primary slurrying reactor, a secondary slurrying reactor group, a pyrohydrolysis reactor, a primary flash evaporation reactor and a secondary flash evaporation reactor; a discharge port of the primary slurrying reactor is connected with feed ports of the secondary slurrying reactors in the secondary slurrying reactor group through a material conveying pump; at least two secondary slurrying reactors are arranged in the secondary slurrying reactor group, discharge ports of the secondary slurrying reactors are connected in parallel and then connected with a feed port of the pyrohydrolysis reactor, and the pyrohydrolysis reactor is sequentially connected with the subsequent flash evaporation reactors in series. According to the invention, the treatment efficiency and the system treatment capacity are greatly improved, and the construction cost of the unit treatment capacity is reduced, that is, under the condition of the same volume of the reactors, the scale of the continuous pyrohydrolysis system is improved by 60%-100% compared with that of a sequencing batch treatment system. The temperature and pressure fluctuation range in the pyrohydrolysis reactor is small, and the steam consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of urban organic solid waste treatment, in particular to a continuous thermal hydrolysis treatment system and method for organic solid waste. Background technique [0002] At present, looking at domestic and foreign thermal hydrolysis systems, the actual production process still mainly adopts the intermittent operation mode, which successively goes through a series of processing processes such as feeding, reaction, pressure relief and discharging. This system has complex technological process, poor stability and low processing efficiency. In the few continuous thermal hydrolysis systems used, volume pumps (such as screw pumps and plunger pumps) are mainly used when transporting fluids with high viscosity, high temperature and high pressure, and above the boiling point High-temperature and high-pressure material quantitative conveying device", but there are many defects in the actual operation process: 1) Wh...
