Abstract
The utility model provides a pneumatic air-drying device consisting of a shaking sieve, an air heater, an air cooler, a steam and water separator, a steam pipeline and a fuel conveying pipeline; the shaking sieve is connected on the fuel conveying pipeline; the air heater is arranged at one end of the fuel conveying pipeline beside the shaker sieve; the air cooler is arranged on the middle section of the fuel conveying pipeline; and the steam and water separator is arranged at the middle rear end of the fuel conveying pipeline. the collected fuel is cut into pieces and dried; subsequently the steam and the water are separated from the fuel; the separated fuel is pneumatically fed subsequently so as to sufficiently vaporize and separate the water in the fuel before entering a boiler; therefore, the fuel entering the boiler is thinned and dried, the combustion efficiency of the fuel is increased, the temperature of the furnace is increased, and the power generation efficiency is improved further. Furthermore, the hot wind used for drying is the waste gas of a steam turbine, so that the waste gas is utilized fully and the environment is protected.
Description
Technical field
The utility model relates to a kind of wind air-supply equipment for drying, is specifically related to a kind of fuel air air-supply equipment for drying of power economized boiler.
Technical background
Along with the development of society, the demand of electric power is increased day by day, a kind of is to arise at the historic moment in the biomass fermentation power station of fuel with stalk, grass, rice husk etc.Send into boiler after the fuel chopping that the many employings in domestic this type of power station at present will be collected and burn the mode that produces the vapours generating, to lack of fuel pre-treatment process.Inevitably can make moist because of a variety of causes and collect fuel such as stalk, grass, rice husk, particularly rainy season, wetness of fuel is excessive, not only expends more heat, and furnace temperature rises not get on, and influences generating efficiency.
Summary of the invention
The utility model has been researched and developed a kind of wind air-supply equipment for drying at above-mentioned deficiency.
The technical scheme that the technical solution problem is adopted is: this device is made up of vibratory sieve, air-heater, air-cooler, steam-water separator, jet chimney and fuel tube, it is characterized in that: vibratory sieve is connected in fuel tube, air-heater is arranged on an end of vibratory sieve next door fuel tube, air-cooler is arranged on the fuel tube stage casing, and steam-water separator is arranged on rear end in the fuel tube.Described vibratory sieve surface is set to 10～30 ° inclination angle.Described jet chimney one end is connected in steam turbine exhaust emission tube road, and an end is connected in the air-heater of this device.The terminal boiler that directly is communicated with of described fuel tube.The moisture that the fuel of collecting will be gone in the as-fired fuel through processes such as chopping, oven dry, carbonated drink separation, wind send fully evaporates separation, improves the fuel generating efficiency.
The beneficial effects of the utility model are: by the pre-treatment to fuel, make the fuel that enters boiler drying in small, broken bits, increase fuel economy, improve furnace temperature, and then improve generating efficiency.And the oven dry usefulness hot blast be the waste gas of steam turbine, waste gas was fully used, protected environment again.
Description of drawings
Accompanying drawing is the utility model side cross-sectional schematic
The specific embodiment
As shown in Figure 1, filtering surface is provided with 10～30 ° inclination angle on the vibratory sieve 1, connects defective material district 2, and vibratory sieve 1 below is provided with a funnel, and the funnel below is connected with fuel tube.Conveyance conduit one end is provided with air-heater 3, and jet chimney 6 is connected with air-heater 3.In the fuel tube stage casing air-cooler 4 is set, the posterior segment is provided with steam-water separator 5, the terminal once-through boiler of fuel tube.
Use: the screen pack that earlier the fuel chopping is transported to vibratory sieve 1 surface when the utility model uses, the screen pack on vibratory sieve 1 surface has 10～30 ° inclination angle, fuel in small, broken bits drains in the funnel through filter screen, effect because of blower fan, produce negative pressure in the fuel tube, be drawn onto in the fuel tube through the fuel of vibratory sieve 1.Fully fuel in small, broken bits does not send chopping again behind defective material district 2.The vapours waste gas that steam turbine produces inserts air-heater 3 by jet chimney 6, air-heater 3 will add hot blast through the fuel that vibratory sieve 1 filters and deliver to the hypomere fuel tube, the fuel of this moment is separated out wherein moisture content through air-cooler 4 coolings again, and by steam-water separator 5 moisture content in the fuel is separated.This moment, dry fuel was blown into boiler by air-cooler again.
