Abstract
The utility model discloses a straw fuel water scrubbing device, which comprises an outer barrel, the outer barrel is provided inside with a rotatable inner barrel, through-holes are distributed all over the inner wall of the inner barrel, the inner barrel is provided inside with a fountain pipe, plural blow heads are distributed around the fountain pipe, the circumambience of the side wall of the inner barrel is provided with plural spiral material guide plates, the material outlet of the inner barrel is provided with a material outlet hopper which can guide fuel out of the barrel. When straw fuel rotates with the inner barrel, straw fuel rotates forwards under the guidance of the spiral material guide plates arranged on the side wall. The plural blow heads distributed around the fountain pipe eject high-velocity flow to continuously wash straw fuel rotating forwards, which eliminates or remarkably decreases the contents of water-soluble matter such as kalium and chlorin, and the like, in straw. When the washed straw is burnt in a boiler, coking will not happen and the boiler will not be eroded, which guarantees the calorific efficiency of the boiler and prolongs the service life of the boiler.
Description
Technical field
The utility model relates to the treatment unit of the stalk fuel of straw boiler, particularly a kind of device with the water-soluble substances eccysis in the stalk.
Background technology
Bioenergy is with low cost because of it, and cleanliness without any pollution, and is advocated.Stalk thermal value height, output are big, are a kind of comparatively ideal bioenergies.Annual production at the various stalks of China reaches 600,000,000 tons, and its thermal value is equivalent to 300,000,000 tons of coals, uses stalk to have broad prospects as the fuel of boiler.Yet, contain more potassium and chlorine in the stalk, when it burnt in boiler, potassium ion can easily produce glass cokings with other materials combinations, and the crystal of coking can be adsorbed on furnace wall, heat transfer tube and the fire grate of boiler, influences the thermo-efficiency of boiler.Simultaneously, the chlorion that stalk contains at high temperature, can corrode boiler, influences the work-ing life of boiler.Wash away stalk by heavy rain, can remove or significantly reduce the potassium in the stalk and the content of chlorine, make it to be not enough to influence the thermo-efficiency and the life-span of straw boiler.But the factor that expectation " heavy rain washes away " this impersonal force can be held, application to the straw boiler generating has brought many difficulties, it had both needed large-area fuel to stack the place, can not guarantee the continuity of supply of fuel again, thereby influenced the security of straw boiler generating.
Because potassium and chlorine all belong to water-soluble substances, can be by washing with its eccysis from stalk.Therefore eccysis potassium chlorine wherein can address the above problem before stalk was sent into boiler combustion.
Summary of the invention
The purpose of this utility model is to provide a kind of stalk fuel water washing device with the water-soluble substances eccysis in the stalk fuel.
Stalk fuel water washing device of the present utility model, it is characterized in that: urceolus is arranged, rotatable inner core is arranged in the urceolus, the sidewall of inner core is covered with through hole, shower is arranged in it, spray pipe ring circumferential direction has a plurality of shower nozzles, is furnished with polylith charging guide plate shape in the shape of a spiral around the sidewall of inner core, and be equipped with the discharge bucket in the fuel export cylinder at inner core discharge port place.
Stalk fuel water washing device of the present utility model, after stalk fuel enters inner core, rotate with inner core, under the polylith charging guide plate guiding of arranging in the shape of a spiral on the sidewall, roll forward, the shower nozzle of spray pipe ring circumferential direction, the high velocity flow of ejection constantly washes the stalk fuel that rolls forward, and eccysis such as the water-soluble substances potassium in the stalk, chlorine or content are significantly reduced.Because potassium, chlorine in the stalk are significantly reduced by eccysis or content, thereby stalk is when the boiler internal combustion, can coking and corrosion boiler, can guarantee the thermo-efficiency of boiler, work-ing life that again can prolonged boiler.Potassium and chlorine eccysis in the stalk, boiler need not use the high temperature corrosion-resisting material to make, and only use general boiler steel to get final product, thereby cost are lower.Simultaneously, it removes potassium and chlorine, need not rely on impersonal force factors such as " rain drop erosiones " to carry out, and it does not need large-area fuel to stack the place, can guarantee the continuity of supply of fuel, thereby can guarantee the continuity and the security of straw boiler generating.
Description of drawings
Fig. 1 is a kind of synoptic diagram of stalk fuel water washing device;
Fig. 2 is a kind of synoptic diagram of stalk fuel water washing device.
Embodiment
As Fig. 1, a kind of stalk fuel water washing device, urceolus 1 is arranged, rotatable inner core 2 is arranged in the urceolus 1, the sidewall 3 of inner core 2 is covered with through hole 4, and shower 5 is arranged in it, and shower 5 ring circumferential directions are furnished with a plurality of shower nozzles 6, screw arrangement has polylith charging guide plate 7 around the sidewall 3 of inner core 2, and be equipped with the discharge bucket in the fuel export cylinder 9 at inner core 2 discharge ports 8 places.Discharge bucket 9 can be tilted-putted bucket-shaped object 9a, also can be the swash plate 9b that there is flange both sides.Shower nozzle 6 on the shower 5 can be shower nozzle, jet pipe or pore etc.
The aperture of above-mentioned stalk fuel water washing device inner core sidewall has the possibility of being stopped up by stalk, in order to prevent little hole plug, influence flowing of water, at inner core 2 and 1 of urceolus recoil tube 10 can be installed, have a plurality of shower nozzles 11 on the recoil tube 10 equally, the through hole that stops up can be washed open by recoil tube 10 ejection current, thereby avoid through hole 4 to be stopped up well by stalk.
Stalk is more, the water yield is bigger, and perhaps during the urceolus impeded drainage, the water yield of accumulating in the tube can be a lot, and water level may exceed the bottom line of discharge port 8, causes ponding to overflow from discharge port 8.In order to prevent that ponding from overflowing from discharge port 8, as Fig. 2, water washing device is equipped with water pump 12, and the inlet 13 of water pump 12 places the ponding place.When the hypervolia that accumulates in the tube, can start water pump 12, it can in time be extracted ponding out, thereby has avoided ponding to overflow.
Water washing device of the present utility model not only can be used for washing stalk fuel, still can be used for washing other materials.
