Abstract
The invention discloses a residual heat-based coal drying system. The system comprises a residual heat oven and a coal conveyor which are connected with each other; and coal is conveyed into the residual heat oven through the coal conveyor for closed drying treatment. Because the temperature of the coal rises, sufficient combustion of the coal dried by the system is facilitated, and the coal consumption is greatly reduced. Furthermore, the coal grinding quality is remarkably improved.
Description
Technical field
The present invention relates to a kind of energy-saving and emission-reduction and environmental protection field, relate in particular to a kind of coal drying system based on waste heat.
Background technology
At present, the waste heat of China's industrial discharge is found everywhere, a lot of waste heats well do not utilize, and most of combustion system is still based on coal, coal contains the Free water major part all more than 10%, and the inherent water that contains is also about 10%, so coal also will evaporate the moisture about 20% in combustion process, so just greatly reduce the caloric value of coal, caused very big energy waste.
Summary of the invention
In order to overcome the problem of energy waste, the invention provides a kind of coal drying system based on waste heat, based on the present invention, can make full use of the waste heat oven dry coal of industrial discharge, help the abundant burning of coal, reduce coal consumption greatly.
A kind of coal drying system based on waste heat of the present invention comprises: waste heat baking oven that is connected and coal conveyer, the oven dry that coal seals in described coal conveyer is delivered to described waste heat baking oven is handled.
Said system, preferred described coal conveyer inserts and is connected in the described waste heat baking oven.
Said system, preferred described system also comprises feeding mechanism, described feeding mechanism comprises first feeding machine, elevator, coal store and second feeding machine that connects successively; Described second feeding machine is connected with the input of described coal conveyer; Wherein, described first feeding machine feeds coal in the described elevator, by described elevator, mentions coal store, by second feeding machine coal is fed described coal conveyer uniformly again.
Said system, preferred described system also comprises coal pulverizer, and described coal pulverizer is connected with the output of described coal conveyer, and the coal of having dried is sent into by described waste heat baking oven and is carried out grinding in the described coal pulverizer.
By the coal of the present invention's oven dry, owing to improved the temperature of coal self, help the abundant burning of coal, greatly reduce coal consumption; And follow-up process of lapping shows that the coal Grinding Quality also significantly improves.
Description of drawings
Fig. 1 is the structural representation that the present invention is based on the coal drying system embodiment of waste heat;
Fig. 2 is the structural representation that the present invention is based on the coal drying system preferred embodiment of waste heat.
The specific embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
The object of the invention is to have realized UTILIZATION OF VESIDUAL HEAT IN oven dry coal, has solved the energy waste phenomenon.
With reference to Fig. 1, Fig. 1 is the structural representation that the present invention is based on the coal drying system embodiment of waste heat, this system comprises waste heat baking oven 7 and the coal conveyer 6 that is connected, and the oven dry that coal seals in described coal conveyer 6 is delivered to described waste heat baking oven 7 is handled.
By this embodiment, realized utilizing waste heat oven dry coal, solved the energy waste phenomenon.
With reference to Fig. 2, Fig. 2 is the structural representation that the present invention is based on the coal drying system preferred embodiment of waste heat.Comprise feeding mechanism, coal conveyer 6, waste heat baking oven 7 and coal pulverizer 8.Wherein, feeding mechanism comprises coal storage bin hopper 1, first feeding machine 2, elevator 3, coal coal store 4 and second feeding machine 5 that connects successively.
Detailed process is coal storage bin hoppers 1 of first fabrication and installation, be first feeding machine 2 below, and then enter elevator 3, rise to, coal is fed in the coal conveyer 6 uniformly by second feeding machine 5 again, the closed operation in waste heat baking oven 7 of coal conveyer enters coal pulverizer 8 through the coal of waste heat baking oven 7 oven dry and grinds.Coal by oven dry has improved Grinding Quality, and coal self temperature is improved, and helps abundant burning, reduces coal consumption greatly.
More than a kind of coal drying system based on waste heat provided by the present invention is described in detail, used specific embodiment herein principle of the present invention and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, part in specific embodiments and applications all can change.In sum, this description should not be construed as limitation of the present invention.
