Abstract
The invention discloses a rotary cement kiln tail waste heat power-generation device which can guide out waste heat on the kiln tail in large area and is simple in structure and capable of adapting to the rotary working state of a rotary kiln. The rotary cement kiln tail waste heat power-generation device comprises a support. A rotary kiln body is rotationally installed on the support. A heat conductive casing pipe is installed on the outer surface of the rotary kiln body. Rotating grooves are evenly formed in the circumferential face of the heat conductive casing pipe. Heat conductive pieces are rotationally installed on the rotating grooves and are of a circular annular structure. The outer surfaces of the heat conductive pieces are fixedly installed on the inner wall of a heat collection casing pipe. The heat collection casing pipe is of a hollow structure and is filled with water. One end of the heat collection casing pipe is provided with a water outlet pipe, and the other end of the heat collection casing pipe is provided with a water inlet pipe. The water inlet pipe is communicated to a water tank, and the water outlet pipe is connected to a boiler. Power is generated after the boiler feeds hot steam into a steam turbine.
Description
Technical field
The present invention relates to the afterheat generating system of cement kiln, be specifically related to the cogeneration of rotary kiln.
Background technology
The kiln tail of manufacture of cement does not generally establish cooling device, the temperature of its kiln tail is lower, because not stall when rotary kiln works is moved, therefore relative other parts of rotary kiln, the low-grade heat source of kiln tail generally all can be wasted, its reason is existing heat-obtaining system because the existence of rotary kiln rotary state causes complex structure, and heat-conducting effect is deteriorated.
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 tail device for generating power by waste heat, kiln tail heat can large-arealy be derived by it, and structure is simple simultaneously, can adapt to the rotation work state of rotary kiln.
The technical solution adopted for the present invention to solve the technical problems is: cement rotary kiln tail device for generating power by waste heat, comprise support, support rotates and installs back rotary kiln body, rotary kiln body outer surface installs thermal conducting sleeve, the outer circumference surface of thermal conducting sleeve offers rotation slot uniformly, rotation slot rotates and installs conducting strip, conducting strip is cirque structure, and the outer surface of conducting strip is fixedly mounted on the inwall of thermal-arrest sleeve pipe; Thermal-arrest sleeve pipe is hollow structure, fills water in it; One end of thermal-arrest sleeve pipe is outlet pipe, and the other end is installed into water pipe, and water inlet pipe is communicated to water tank; Outlet pipe is connected to boiler, and boiler generates electricity after vapours is sent into steam turbine.
Further: above-mentioned outlet pipe, water inlet pipe is all provided with valve, and water pump installed by water inlet pipe.
The invention has the beneficial effects as follows:
Cement rotary kiln tail device for generating power by waste heat of the present invention, by carrying out heat conduction at kiln tail (part for rotary kiln body) outer wrap thermal conducting sleeve, thermal-arrest sleeve pipe is installed in rotation on thermal conducting sleeve, thermal-arrest sleeve pipe carrys out heat conduction by rotating the conducting strip installed, heat is caused thermal-arrest sleeve pipe by conducting strip on the one hand fast, can ensure that thermal-arrest sleeve pipe can not rotate on the other hand while rotary kiln rotates; Thermal-arrest sleeve pipe is used for heating water, and final water only needs boiler heating of simply gasifying to realize steam-electric power.

Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the invention is described:
Fig. 1 and Fig. 2 shows the specific embodiment of the present invention, as shown in the figure, cement rotary kiln tail device for generating power by waste heat of the present invention, comprise support 1, support 1 rotates and installs back rotary kiln body 2, rotary kiln body 2 outer surface installs thermal conducting sleeve 5, the outer circumference surface of thermal conducting sleeve 5 offers rotation slot 9 uniformly, rotation slot 9 rotates and installs conducting strip 8, conducting strip 8 is cirque structure, and the outer surface of conducting strip 8 is fixedly mounted on the inwall of thermal-arrest sleeve pipe 6; Thermal-arrest sleeve pipe 6 is hollow structure, fills water in it; One end of thermal-arrest sleeve pipe 6 is outlet pipe 3, and the other end is installed into water pipe, and water inlet pipe is communicated to water tank 7; Outlet pipe 3 is connected to boiler, and boiler generates electricity after vapours is sent into steam turbine.
Preferably, above-mentioned outlet pipe 3, water inlet pipe is all provided with valve 4, water pump is installed by water inlet pipe.
By reference to the accompanying drawings the preferred embodiment for the present invention is explained in detail above; but the invention is not restricted to above-mentioned embodiment, all improvement in the ken that those of ordinary skill in the art possess carried out based on thought of the present invention all drop in protection scope of the present invention.
Do not depart from the spirit and scope of the present invention and can make other changes many and remodeling.Should be appreciated that and the invention is not restricted to specific embodiment, scope of the present invention is defined by the following claims.
