Description
Technical field
The utility model relates to a kind of TRT, refers in particular to the TRT that the waste heat that can utilize tunnel cave generates electricity, and is specially novel tunnel kiln device for generating power by waste heat.
Background technology
Energy-saving and emission-reduction and comprehensive utilization of resources are the important state basic policies of protecting environment, building a harmonious society, realize sustainable economic development.Utilize the waste heat of Industrial Stoves equipment to generate electricity, be economize on resources, the effective way of the energy.At present, the device that utilizes the waste heat of Industrial Stoves equipment to generate electricity comprises: be arranged on the heat exchanger in the tunnel cave, the media recycler that is connected with heat exchanger, the engine that is connected with media recycler, the generator that is connected with engine; Heat exchanger generally comprises superheater and evaporimeter.Media recycler generally comprises condenser, condensate pump, water tank etc.Engine is a steam turbine.The generator steam turbine generator.And prior art all is that heat exchanger with boiler is arranged in the flue between Thermal Equipment and the chimney (high temperature section of tunnel cave), and the generating set that is adopted is a Turbo-generator Set.This device is to the quality requirements height of waste heat, only utilizing high-temperature residual heat, and changes or waste heat quality when low when the operation system of Industrial Stoves, and its application just is subjected to certain limitation, and efficient is had a greatly reduced quality.
Summary of the invention
The utility model provides a kind of novel tunnel kiln device for generating power by waste heat at the problems referred to above that existing residual heat of tunnel kiln TRT exists.
The utility model has adopted following technical scheme to realize above-mentioned purpose: a kind of novel tunnel kiln device for generating power by waste heat, comprise the heat exchanger that is arranged in the tunnel cave, the media recycler that is connected with heat exchanger, the engine that is connected with media recycler, the generator that is connected with engine; Heat exchanger is arranged on the low temperate zone of tunnel cave; Engine is the vapour-liquid Hydrodynamic machine, and generator is the screw expansion generator.The interconnection technique of heat exchanger and boiler, heat exchanger and media recycler, media recycler and engine, engine and generator is prior art.The low temperate zone of tunnel cave is meant the clinkering zone end and the salband of tunnel cave.
The utility model has overcome the high request of prior art to waste heat, has enriched thermal source, and medium is easily produced, thermal efficiency height; The utility model is simple in structure, easy to operate, efficient, durable, operating mode is wide; Variable parameter operation on a large scale, when 40-100% loaded, internal efficiency was 65%-80%; Can bear bigger impact electric load, can be widely used in power set, small power generation, cogeneration system, compare with the Steam Turbine generation mode: cost of investment is low, generating efficiency is high.Particularly use vapour-liquid mixed phase vapor stream, system can be according to the periodic duty of thermodynamics triangle, and heat loss is little, the cycle efficieny height, and under equal conditions Power Recovery exceeds 60% than steam turbine Rankine cycle.As the steam boiler that utilizes pressure 1.0-1.6MPa produces the wet saturated steam of mass dryness fraction 80%, and acting back vapour-liquid fluid directly is compressed into the liquid-vapor mixture of pressure 1.2-1.8MPa and returns steam boiler thermal cycle again, reduces the loss of the cooling energy consumption and the latent heat of vaporization; It is few that system's sealing and circulating consumes the water yield.Vapour-liquid fluid-driven power generator group is to reclaim and efficiently utilize a kind of advanced effective technical of industrial low-temperature waste heat and combustible exhaust gas resource.Therefore, the utlity model has good application prospects.
