Abstract
The utility model relates to a fuel dryer for a biomass power plant. The fuel dryer consists of a housing, a hopper, a conveyer belt, a flipper, a warm-air duct and an exhaust pipe, wherein the hopper is arranged above one end of the conveyer belt; the flipper is arranged above the conveyer belt; the warm-air duct is arranged at an outlet of the conveyer belt; and all the equipment are arranged in the sealed housing. The fuel dryer effectively utilizes the hot waste gases, smoke and other waste generated in the power generation process to dry the fuel, so that the environmental pollution is reduced; and through drying the fuel, the combustion value of the fuel is improved, the generating efficiency is further improved, and the generating cost is lowered.
Description
Technical field
The present invention relates to a kind of dryer, be specifically related to a kind of fuel dryer of biomass power generation station-service.
Background technology
Biomass fermentation power plant be a kind of be the power plant of fuel combustion generating with stalk, grass, rice husk, bark, tree root etc.And all there is the bigger problem of water content in above-mentioned fuel, when particularly arrive rainy season, because the water-in-fuel amount is bigger, will consume more heat in combustion process, and furnace temperature is not easy control, and then influences generating efficiency.Through investigation, still incompetent in the market effectively satisfied relevant device of fuel being dried processing.
Summary of the invention
The present invention is directed to above-mentioned weak point, researched and developed a kind of biomass electric power plant fuel dryer, purpose is effectively fuel to be dried processing, increases fuel value, and then improves generating efficiency.
Technical solution of the present invention
A kind of biomass electric power plant fuel dryer, form by case, hopper, conveyer belt, the diffusing device of throwing, hot air duct, blast pipe, it is characterized in that hopper is arranged on the top of conveyer belt one end, the conveyer belt top is provided with the diffusing device of some throwings, throw the device that looses by motor-driven, the conveyer belt exit is provided with hot air duct, and all devices all is arranged in the seal casing.
Described case inside is provided with one deck conveyer belt at least, and every layer of conveyer belt top is provided with one at least and throws the device that looses.
The diffusing device of described throwing is made up of power transmission shaft and plectrum, by motor or conveyer power drive.
Beneficial effect of the present invention
1. utilize the hot waste gas that produces in the power generation process, flue gas etc. that fuel is dried processing, carried out twice laid effectively, alleviate environmental pollution.
2. handle by oven dry, improved the fuel value of fuel, and then improve generating efficiency, reduced cost of electricity-generating fuel.
Description of drawings
Fig. 1 is a side of the present invention cross-sectional schematic.
Fig. 2 throws the device schematic side view of loosing for the present invention
The specific embodiment
As shown in Figure 1: hopper 5 is arranged on the top of conveyer belt 1 one ends, blast pipe 4 is arranged on the top of case 3, three layers of conveyer belt 1 are set in the case 3, every layer of conveyer belt top all is provided with throws the device 2 that looses, end in case 3 bottoms, oven dry material exit is provided with hot air duct 6, and hot air duct 6 belows are provided with the outlet of conveyer belt 1.
As shown in Figure 2: throw the device that looses and form by power transmission shaft 8 and plectrum 7.
The concrete course of work:
Open hot air duct 6 earlier, used heat wind that produces in the power generation process and flue gas enter case 3 inside through hot air duct 6, fuel with humidity enters on the conveyer belt 1 by hopper 5 then, conveyer belt 1 is fed forward the material of humidity, be full of useless hot blast and flue gas in the case this moment, power transmission shaft 8 rotates under power drive on the diffusing device 2 of throwing, and moist fuel is constantly thrown with used heat wind by the plectrum 7 on the diffusing device 2 of throwing and fully contacted with flue gas, and the moisture in the process fuel of heat exchange is partly evaporated; Second layer conveyer belt and ground floor conveyer belt throughput direction are on the contrary with conserve space, second layer conveyer belt one end is slightly longer than ground floor conveyer belt one end, fuel falls on second layer conveyer belt after the ground floor conveyer belt falls, and fuel is thrown to continue fully to contact with used heat wind and flue gas and evaporated wherein moisture content by the throwing of the second layer conveyer belt top device 2 that looses; The 3rd layer of conveyer belt is opposite with second layer conveyer belt throughput direction, and fuel is fallen the 3rd layer of conveyer belt after second layer conveyer belt falls down, and fuel is thrown once more with used heat wind in the 3rd layer of conveyer belt course of conveying and fully contacted with flue gas.The temperature of case 1 bottom is than the height on top, so throwing the device that looses through three layers of conveyer belt and several, fuel carried out fully contacting with used heat wind and flue gas, the water content that it's time to export in the fuel has been in floor level, after testing, meets the water-in-fuel amount less than 30% requirement.Used heat wind and flue gas through heat exchange enter postprocessing working procedures by the blast pipe 4 that is arranged on case 3 tops.
To sum up, the present invention has reached intended purposes.
