Garbage disposal waste heat power generation system with internal steam pipe

Abstract

The invention discloses a garbage disposal waste heat power generation system with an internal steam pipe, which comprises a garbage gasifier and a turbine steam power generation device. The turbine steam power generation device comprises a steam generator, a steam discharge pipe, a steam drum, a steam turbine and a power generator, wherein the steam drum, the steam turbine and the power generator are sequentially connected, and the steam generator is arranged in the garbage gasifier and is of a cylindrical cage type structure comprising an upper annular pipe, a plurality of straight pipes and a lower annular pipe. As the steam generator is arranged in the garbage gasifier to realize primary heat exchange and a heat exchanger is additionally arranged in a flue gas channel to realize secondary utilization, heat generated in garbage disposal is used to the maximum extent, the technique with low heat utilization rate of a waste heat boiler for traditional garbage disposal steam power generation in the past is thoroughly changed, and garbage disposal heat recovery is maximized. Owing to a four-step hydraulic pusher, garbage is increasingly looser in the process of entering the garbage gasifier, and is not blocked.

Description

technical field [0001] The invention relates to waste treatment power generation equipment, in particular to a waste heat power generation system for waste treatment which recycles various garbage (organic matter) after treatment and the generated waste gas has been purified. Background technique [0002] Biomass energy refers to various organisms produced by photosynthesis. Bioenergy is an energy form in which solar energy is stored in organisms in the form of chemical energy, and it is an energy that uses biomass as a carrier. Biomass gasification refers to the use of combustible gases produced by anoxic combustion of plant stems, branches, leaves, straw, chaff, industrial solid organic waste, etc., for various purposes. [0003] The biomass resources in the world are huge in quantity and in various forms, such as firewood, agricultural and forestry crops, agricultural and forestry residues, leftovers from food processing and forest product processing, and urban solid wast...

Problems solved by technology

The existing waste treatment technology is landfill, accounting for 85%, composting 10%, incineration 3-5%, but these three treatment methods have shortcomings: landfill occupies a large area, releases harmful gases, pollutes groundwater, brings Secondary pollution; compost sorting process is complex, high cost, low fertilizer efficiency, no market for compost products; low incineration temperature, easy to form dioxin-like toxic substances, causing secondary pollution, and huge investment, long construction period, operation and maintenance costs high, difficult to maintain
