Resource regeneration processing method and equipment for urban sewage sludge

Abstract

The invention discloses a resource treatment method for municipal sludge and equipment thereof. The method comprises the following steps that: the dried sludge is subject to carbonization treatment with a carbonization temperature range of between 450 and 650 DEG C and molded to produce a solid product; carbonization fractions in the carbonization treatment are reclaimed and a condensate is separated off; purified wood coal gas is comprehensively utilized; through a carbonization process adopting a biomass dynamic carbonization and pyrogenation comprehensive treatment technology, feeding, drying, carbonization, carbon generation, the dust removal of wood coal gas, condensation, washing and the separation of various byproducts can be continuously completed; carbonization equipment can realize automatic operation and can carry out resource treatment to biomass; the adopted process has strong adaptability to the variety and humidity of the biomass and has small loss of biomass and high treatment efficiency in the treatment process; as the process adopts a full-closed carbonization furnace, product yield is all products, wherein, the produced wood coal gas is used as fuel for drying, carbonization or power generation, thereby reducing production cost; and the whole system has perfect design and reasonable economical technology.

Description

Technical field [0001] The patent of the present invention relates to a sludge treatment method, in particular to a resource treatment method and equipment of urban sludge. Background technique [0002] In the past period, some regions did not seriously consider protecting the environment while developing the economy. As a result, the environmental situation deteriorated, which severely restricted economic development and caused the deterioration of the living environment of human settlements. Facts proved that this development path was unworkable. In the new era today, the development and protection of the environment, and environmental protection requirements have been put in the first place. That's why there is a government-managed environmental protection one-vote veto system. The environmental protection work in the production development process and the construction of living facilities is mainly the treatment of the three wastes (waste residue-solid waste, waste water and ...
