Abstract
The invention discloses a cement kiln waste heat power generating device which has high rotary kiln outer surface heat extracting efficiency and high hot water steam using efficiency. According to the cement kiln waste heat power generating device, a circulating water bag is arranged on the outer surface of a rotary kiln in a wrapping mode, the circulating water bag is filled with water and comprises a cold water inlet and a hot water outlet, the cold water inlet is connected with a water tank through a pipeline, the hot water outlet is connected with a boiler through a pipeline, the boiler conveys hot water steam to a steam turbine through a pipeline, and the steam turbine is connected with a power generator. The steam turbine collects steam-water mixtures passing through the steam turbine through a recycling water pipeline which is communicated with the inner portion of the water tank through the hot end of a thermoelectric power generation module. The cold end of the thermoelectric power generation module is cooled through a circulating cooling pipeline, and a cooling spraying tower is arranged on the circulating cooling pipeline.
Description
Technical field
The present invention relates to the device for generating power by waste heat of cement kiln, be specifically related to the cogeneration of cement rotary kiln.
Background technology
The kiln surface temperature of cement rotary kiln is higher, and the temperature of this part does not utilize by traditional cement rotary kiln, causes waste, and existing cement kiln residual heat generating device generates electricity after the heat extraction of this part by producing steam after boiler heating; Existing cement kiln residual heat generating device, the utilization rate of kiln external surface heat is inadequate, and meanwhile, steam is after steam turbine power generation, and it is cooled by air conditioner, and the low-temperature heat quantity of this part is slatterned, and air conditioner also needs electric energy to do work simultaneously.
Summary of the invention
The present invention is directed to the deficiency that above-mentioned prior art exists, provide a kind of cement kiln residual heat generating device, it has higher rotary kiln outer surface heat extraction efficiency, and higher hot water and steam utilization ratio.
The technical solution adopted for the present invention to solve the technical problems is: cement kiln residual heat generating device, recirculated water bag installed by the outer surface parcel of rotary kiln, water is filled in recirculated water bag, it comprises cold water inlet and hot water outlet, cold water inlet connects water tank by pipeline, hot water outlet connects boiler by pipeline, boiler by hot water and steam by Pipeline transport to steam turbine, steam turbine connect generator;
Above-mentioned steam turbine collects the steam water interface after steam turbine by recycle-water pipeline; Reclaim line is communicated to water tank inside behind the hot junction of temperature-difference power generation module; The cold junction of above-mentioned temperature-difference power generation module is lowered the temperature by circulating cooling pipeline, circulating cooling pipeline is provided with chilling spray tower.
Further: above-mentioned water tank also offers water supplement port, this water supplement port is by water pipe moisturizing.
Further: the structure of above-mentioned recirculated water bag is the water bag of the heat conducting film formation of sealing.
The invention has the beneficial effects as follows:
Cement kiln residual heat generating device of the present invention, rotary kiln surface is wrapped up by water bag, therefore it more directly can absorb the heat of kiln surface to a greater extent, meanwhile, hot water and steam sends into the hot junction of temperature-difference power generation module after steam turbine, the temperature difference is sent out point module and is utilized this low grade heat energy again to generate electricity, and sends into water tank after hot water and steam being herein converted into water completely simultaneously.
