Description
Technical field
The utility model relates to the design field of hazardous waste afterheat generating system.
Background technology
Along with industrial expansion, the hazardous waste of industrial processes discharge is increasing.The steam quality produced after the process of danger waste burning is low, and under conventional art restriction, enterprise is except self employs, and can only discharge, not only cause environmental pollution, and cause larger energy waste to sky.By the waste heat in remanufacture technical process, produce other thermal demand that steam is used for electricity generation grid-connecting or meets productive life, realize cascaded utilization of energy, raising efficiency of energy utilization has become the problem that the useless industry development of danger must be considered.
Utility model content
The utility model object is, for above problem, to provide a kind of economize energy, realize cascaded utilization of energy, improves the hazardous waste afterheat generating system of efficiency of energy utilization.
The utility model comprises feed system, rotary kiln, dual firing chamber, waste heat boiler, screw machine, generator, stram condenser, condensate tank, condensate pump, running water water inlet, water softener, softened water tank, oxygen-eliminating device, water service pump, boiler feed pump; The output of described feed system is connected with the input of rotary kiln, and the output of described rotary kiln is connected with the input of dual firing chamber; Described waste heat boiler comprises flue gas input, gas cleaning output, soft water input and reclaims heat energy output end; The output of described dual firing chamber is connected with the flue gas input of waste heat boiler; The recovery heat energy output end of described waste heat boiler is connected with the input of screw machine by pipeline, and described screw machine is connected with generator; The exhaust steam outlet of described screw machine is connected with the input of stram condenser by pipeline, the output of described stram condenser is connected with the input of condensate tank, the output of described condensate tank is connected with the input of condensate pump, and described condensate water delivery side of pump is connected with the condensed water input of oxygen-eliminating device; Described water softener, softened water tank, water service pump are connected between running water water inlet to oxygen-eliminating device by water pipe successively; The output of described oxygen-eliminating device connects the input of boiler feed pump, and described boiler feedwater delivery side of pump is connected with the soft water input of waste heat boiler.
In use, solid dangerous waste pours feed hopper into the utility model, enters rotary kiln front end through feed system equipment; Liquid wastes are sent to rotary kiln main burner and dual firing chamber two combination burners respectively by noncorrosive pump and burn.The high-temperature flue gas that burning produces enters dual firing chamber and burns away, the temperature of dual firing chamber controls between 1100 ~ 1200 DEG C, flue gas time of staying in dual firing chamber will be greater than 2s, and with this understanding, in flue gas, bioxin will be broken off with more than 99.99% of other harmful components.Dual firing chamber's outlet high-temperature flue gas enters waste heat boiler.Boiler inlet flue-gas temperature 1150 DEG C, outlet temperature 550 DEG C, discharges after gas cleaning is up to standard from waste heat boiler flue gas out.Waste heat boiler adopts fin panel casing steam boiler.Partial heat energy in flue gas reclaims by waste heat boiler, and the steam of generation is done work by screw machine, and drive electrical generators generates electricity.Exhaust steam in screw machine after acting is cooled by stram condenser, after condensing into water, flows into condensate tank reuse.And force to send into waste heat boiler drum use as boiler soft water through oxygen-eliminating device water pump, thermal deaerator, boiler feed pump, supply line together with the water of softening water tank.The utility model economize energy, realize cascaded utilization of energy, improve efficiency of energy utilization.
