Abstract
The invention discloses a waste heat power generation device of a rotary cement kiln body. Since electric energy is generated through thermoelectric power generation, the whole power generation device is simpler in structure. The waste heat power generation device of the rotary cement kiln body is characterized in that the rotary cement kiln body is mounted on a support frame rotationally, a heat-conductive sleeve coats the rotary cement kiln body, a plurality of mounting grooves are formed in the heat-conductive sleeve evenly, and thermoelectric power generation components are mounted in the mounting grooves; each thermoelectric power generation component comprises a high-temperature surface and a low-temperature surface, the high-temperature surfaces are embedded into the mounting grooves, and the depths of the mounting grooves are higher than the thicknesses of the high-temperature surfaces; radiator pieces are mounted on the outer surfaces of the low-temperature surfaces. Moreover, all the thermoelectric power generation components are convergently connected to a guide line which is connected with an external cable through an electricity-conductive sliding ring.

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 waste-heat power generation system is steam-electric power, and it needs boiler to heat, system configuration relative complex.
Summary of the invention
The present invention is directed to the deficiency that above-mentioned prior art exists, provide a kind of cement rotary kiln body device for generating power by waste heat, it produces electric energy by thermo-electric generation, makes whole power generation system structure more simple.
The technical solution adopted for the present invention to solve the technical problems is: cement rotary kiln body device for generating power by waste heat, support rotates and installs back rotary kiln body, rotary kiln body outer surface wraps up one deck heat conducting sleeve, and heat conducting sleeve evenly offers multiple mounting groove, installs thermo-electric generation assembly in mounting groove;
Described thermo-electric generation assembly comprises high temperature face and low temperature face, and described high temperature face is embedded in above-mentioned mounting groove, and the degree of depth of described mounting groove equals the thickness of high temperature face; Described low temperature face outer surface is provided with radiator fin.
Further: above-mentioned all thermo-electric generation assemblies all collect and are connected on wire, and wire is connected with extraneous cable by conducting slip ring.
The invention has the beneficial effects as follows:
Cement rotary kiln body device for generating power by waste heat of the present invention, generated electricity by thermo-electric generation assembly, therefore its whole system does not need boiler and supply equipment, system configuration is relatively simple, meanwhile, the high temperature face of thermo-electric generation assembly, in order to increase generating efficiency, embeds in heat conducting sleeve by the present invention completely, and therefore the absorption temperature effect of high temperature face is better.
