Abstract

The invention relates to a modular sludge thermal hydrolytic treatment device and method. The device comprises a steam feeding main valve, a steam releasing main valve and three-five hydrolytic modules, wherein the steam feeding main valve is arranged at the inlet of a steam main pipeline, the steam releasing main valve is arranged at the outlet of the steam main pipeline, the inlet of each of the hydrolytic modules is connected with the inlet of the steam main pipeline, and the outlet of each of the hydrolytic modules is connected with the outlet of the steam main pipeline; each hydrolytic module comprises a steam feeding valve, a thermal hydrolytic reactor, a steam releasing valve and a waste steam feeding valve; the inlet of the steam feeding valve is connected with the inlet of the steam main pipeline, the outlet of the steam feeding valve is connected with the inlet of the thermal hydrolytic reactor and the outlet of the waste steam feeding valve in parallel, the outlet of the thermal hydrolytic reactor is connected with the inlet of the steam releasing valve, and the outlet of the steam releasing valve and the inlet of the waste steam feeding valve are connected with the outlet of the steam main pipeline; each thermal hydrolytic reactor is internally provided with a temperature sensor and a pressure sensor, and each temperature sensor and each pressure sensor send collected temperature values an pressure values to an automatic control system.

Description

technical field [0001] The invention relates to a sludge treatment device and method, in particular to a modular sludge thermal hydrolysis treatment device and method. Background technique [0002] With the continuous improvement of sewage treatment capacity and sewage treatment rate, the sludge output of sewage treatment plants has also increased. In the development of sewage treatment in our country, although sludge is one of the important links in the sewage treatment process, due to long-term lack of understanding and neglect, the problem of sludge disposal in urban sewage treatment plants in my country has been shelved for a long time, and the importance of sludge disposal The development is quite lagging behind, and the secondary pollution caused by sludge is becoming more and more prominent. It is urgent to solve the problem of safe disposal of sludge. Sludge treatment, like other solid waste treatment, should follow the principles of reduction, stabilization, and har...
