Abstract

The invention relates to a sludge disintegration device. The sludge disintegration device comprises a subcritical reaction tank group, a heater, a dryer and a fluidized pyrolysis device, wherein the subcritical reaction tank group is used for high-temperature pressurization of primary sludge and enables the primary sludge to be in a subcritical state to be pyrolyzed so as to obtain a sludge pyrolysis liquid; the heater is connected with the subcritical reaction tank group and used for providing the subcritical reaction tank group with heat; the dryer is connected with the subcritical reaction tank group and used for drying the sludge pyrolysis liquid to obtain sludge powder; the fluidized pyrolysis device is connected with the dryer and used for pyrolyzing the sludge powder to obtain powdered carbon. As the subcritical reaction tank group and the fluidized pyrolysis device are arranged, primary sludge can be firstly subjected to subcritical high-temperature pyrolysis reaction, then the sludge powder obtained by drying is subjected to fluidized pyrolysis reaction to obtain powdered carbon, accordingly, most biological cells in primary sludge are ruptured, the molecular chains of long-chain organic matters are to be ruptured, and primary sludge can be pyrolyzed more sufficiently. The carbonization effect is good, and the carbonization time is short.

Description

Technical field [0001] The invention relates to the field of sludge treatment, in particular to a device for sludge decomposition. Background technique [0002] The existing sludge drying device directly heats and dries the sludge when drying the sludge, and the obtained dried sludge still contains a lot of organic substances or pollutants, which may cause environmental pollution to be discharged outdoors. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a device for sludge decomposition based on the shortcomings of the prior art. [0004] The technical solution of the present invention to solve the above technical problems is as follows: A device for sludge decomposition, including: [0005] The subcritical reaction tank group is used to pressurize the original sludge at high temperature, so that the original sludge enters a subcritical state for cracking to obtain a sludge cracking solution; [0006] A heating device, the he...
