Abstract
The utility model relates to a boiler coal slime middle feeder, a pusher which consists of a spiral shaft and a spiral piece is arranged in an inner cavity of a housing of a cylinder body, the back end of the spiral shaft is connected with rotational power, a discharge outlet is arranged at the front end of the housing, a feed inlet is arranged on the upper side surface of the back part of the housing, a water cooling sleeve is wrapped on the periphery of the front part of the housing, a water inlet and a water outlet are arranged on the water cooling sleeve, a flush port which is communicated with the inner cavity is arranged on the housing, and a three-way ball valve is connected on the flush port. The boiler coal slime middle feeder realizes the boiler middle coal slime spiral feeding after being matched with impurity removal of coal slime and sent by a high-pressure pump, the coal slime is directly spirally extruded into a positive-pressure boiler for burning from the middle-lower part of the boiler, the coal slime does not need to be atomized by compressed air before entering the boiler, and the boiler coal slime middle feeder is combined with an original imported feeding system for use, thereby greatly improving the blended ratio of the coal slime; the coal slime is cut into coal slime pieces and enters a boiler chamber for sufficient burning, thereby avoiding the phenomena of caking and coking of the coal slime; and compressed air atomization is not needed, energy consumption is low and the maintenance cost of an air compressor is reduced.
Description
Technical field:
The utility model relates to a kind of boiler coal slime middle part dispenser, is used for coal slime is directly fed boiler combustion from the CFBB middle and lower part.
Background technology:
The main small-sized CFBB below 220t/h that uses of coal slime carried out in the past, the mode that adopts mainly contains furnace roof feed, oven dry back and raw coal multifuel combustion, bottom spray combustion etc., in big-and-middle-sized pressurized boiler, removing the bottom spray combustion had the elder generation's of use exception, and other use mode does not have successful experience.Realize that coal slime mixes burning at the vast scale of big-and-middle-sized CFBB, oven dry back multifuel combustion obviously can not reach requirement, and owing in the big-and-middle boiler hearth of circulating fluidized bed screen formula heat exchanger is arranged, the furnace roof feed can cause hot-spot, burning some row problems such as insufficient.Boiler bottom sprays precedent is arranged successfully, is import equipment but system adopts, and needs the atomizing air of a large amount of HTHPs in the system, and not only equipment and fittings cost costliness, and operation is economical inadequately.Coal slime middle part feed can directly feed the burner hearth burning from secondary wind compact district, boiler middle and lower part, can reduce the operating cost of system greatly, needs to design coal slime middle part dispenser for this reason.
Summary of the invention:
The purpose of this utility model provides a kind of boiler coal slime middle part dispenser, can be implemented in boiler middle part coal slime feed, thereby reduce the boiler operatiopn expense.
The purpose of this utility model realizes as follows: the pusher that is made of helical axis and flight is housed in the inner chamber of simplified shell, the rear end of helical axis connects rotary power, the shell front end has discharging opening, shell rear portion upper side has charging aperture, the anterior periphery of shell is surrounded by water(-cooling) jacket, and a water inlet and a delivery port are arranged on the water(-cooling) jacket.Coal slime enters shell inner cavity from charging aperture, is cut into thin type sheet coal slime piece by flight, is convenient to coal slime fully burning in dropping process, can effectively avoid the caking coking of coal slime.The cooling water that circulates that injects in the water(-cooling) jacket can be lowered the temperature for through walls section to dispenser, plays a protective role.
A rinse mouth that communicates with inner chamber is arranged on the shell, connect tee ball valve on this rinse mouth.Tee ball valve can select motor-driven valve, and joins with wash tub pipe and blow-off pipe, during to the coal slime flushing of pipeline, the sludge water switching of flushing of pipeline is led in the slurry pond.
The beneficial effects of the utility model are: cooperate realizing boiler middle part coal slime screw feeder after coal slime removal of impurities, the high pressure pumping, coal slime is advanced the pressurized boiler burning from the direct screw extrusion in boiler middle and lower part, coal slime is gone into the stokehold needn't compressed air atomizing, with former import feeding system and usefulness, coal slime is mixed burn than significantly improving; Coal slime is cut into the coal slime sheet enter burner hearth and fully burn, avoided coal slime caking coking phenomenon; Need not the compressed air atomizing, energy consumption is low, and has reduced the air compressor machine maintenance cost.
Description of drawings:
Fig. 1 is the front view of the utility model boiler coal slime middle part dispenser.
Fig. 2 is the vertical view of the utility model boiler coal slime middle part dispenser.
The specific embodiment:
With reference to Fig. 1, Fig. 2, the pusher that is made of helical axis 7 and flight 6 is housed in the inner chamber of cylinder shell 8, the rear end of helical axis 7 connects reductor 10 output shafts, the power shaft of reductor 10 connects motor 12, and shell 8 front ends have discharging opening 1, and shell 8 rear portion upper sides have charging aperture 9, the anterior periphery of shell 8 is surrounded by water(-cooling) jacket 2, a water inlet 3 and a delivery port 4 are arranged on the water(-cooling) jacket 2, a rinse mouth that communicates with inner chamber 5 is arranged on the shell 8, connect tee ball valve 11 on this rinse mouth 5.Water(-cooling) jacket 2 is used to inject cooling water and can lowers the temperature for through walls section to dispenser; When tee ball valve 11 is used for the coal slime flushing of pipeline, the sludge water switching of flushing of pipeline is led in the slurry pond.
Claims (2)
1, dispenser in the middle part of a kind of boiler coal slime, the pusher that is made of helical axis and flight is housed in the inner chamber of cylinder shell, the rear end of helical axis connects rotary power, the shell front end has discharging opening, shell rear portion upper side has charging aperture, it is characterized in that: the anterior periphery of shell (8) is surrounded by water(-cooling) jacket (2), and a water inlet (3) and a delivery port (4) are arranged on the water(-cooling) jacket (2).
