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 drying system of coal 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 take coal as main, coal contains the Free water major part all more than 10%, and the inherent water that contains is also in 10% left and right, so coal also will evaporate the moisture of 20% left and right in combustion process, so just greatly reduce the caloric value of coal, caused very large energy waste.
Summary of the invention
In order to overcome the problem of energy waste, the invention provides a kind of drying system of coal based on waste heat,, based on the present invention, can take full advantage of the residual heat drying coal of industrial discharge, be conducive to the abundant burning of coal, greatly reduce coal consumption.
A kind of drying system of coal based on waste heat of the present invention comprises: the waste heat baking oven that is connected and coal conveyer, coal seals in described coal conveyer is delivered to described waste heat baking oven drying and processing.
Said system, preferred described coal conveyer inserts and is connected in described waste heat baking oven.
Said system, preferred described system also comprises feeding mechanism, described feeding mechanism comprises the first feeding machine, elevator, coal coal store and the second feeding machine that connects successively; Described the second feeding machine is connected with the input of described coal conveyer; Wherein, described the first feeding machine, in the described elevator of coal feeding,, by described elevator, is mentioned the coal coal store, then by the second feeding machine, coal is fed described coal conveyer uniformly.
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 in described coal pulverizer and is carried out grinding by described waste heat baking oven.
Coal by the present invention is dried,, due to the temperature that has improved coal self, be conducive to the abundant burning of coal, greatly reduces coal consumption; And follow-up process of lapping shows, 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, coal seals in described coal conveyer 6 is delivered to described waste heat baking oven 7 drying and processing.
By this embodiment, realized utilizing residual heat drying 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, the first feeding machine 2, elevator 3, coal coal store 4 and the second feeding machine 5 that connects successively.
Detailed process is coal storage bin hoppers 1 of first fabrication and installation, it is below the first feeding machine 2, and then enter elevator 3, rise to coal coal store 4, coal is fed in coal conveyer 6 uniformly by the second feeding machine 5 again, the closed operation in waste heat baking oven 7 of coal conveyer, enter coal pulverizer 8 through the coal of waste heat baking oven 7 oven dry and grind.Coal by oven dry, improved Grinding Quality, and coal self temperature is improved, and is conducive to abundant burning, greatly reduces coal consumption.
Above a kind of drying system of coal based on waste heat provided by the present invention is described in detail, applied 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, all will change in specific embodiments and applications.In sum, this description should not be construed as limitation of the present invention.
