Abstract
The utility model belongs to the technical field of the slag tapping device for pressure firing coal chamber in MHD (magnetohydrodynamics) power generation. The device and technology are characterized in a small slag outlet, a dump mechanism, rotational flow slag tapping and secondary quenching and granulating clinker. The granulated slag is discharged by a bearing can system and a variable pressure can system. The device can continuously and stably discharge clinkers in the firing coal chamber, and a program control device is added to realize automatic control. The technology of the device can be used for other pressure slag tapping combustion chambers or coal gasification stoves.
Description
The present invention is the slag tap device of coal-fired pressurized firing chamber, belongs to the slag tap technical field of the coal-fired pressurized firing of magnetohydrodynamic generator chamber.
Slag tap combustion chamber, power station (boiler) is moved under normal pressure; the liquid lime-ash of its fusion directly falls in the uncovered slag granulation water tank by slag-drip opening; the extinguishing granulation, people's such as M.Bauer article " Continuousoperation 20 MW in 20 magnetic fluid annual meetings of the U.S.
TMHD Coal Combustor " slag-draining device of (moving megawatt magnetohydrodynamic generator fired coal combustion chambers 20 continuously) (annotate 1) MHD fired coal combustion chamber of discussing.Its slag-drip opening is big especially, and this will bring bigger radiation heat loss to become estranged to reduce effective swept volume of combustion chamber.
The objective of the invention is to overcome U.S. MHD(magnetohydrodynamics) shortcoming on the slag tap apparatus structure of generating fired coal combustion chamber, it is little to create a kind of radiation heat loss, the effective swept volume in combustion chamber is big, can discharge the technique device of molten slag under positive pressure continuously and stably.
Particular content of the present invention is: slag-drip opening (2) be sudden expansion (
Shape) its aperture that is connected with the combustion chamber (12) of structure (seeing figure) is less, and the slag-drip opening inwall evenly covers one deck insulating refractory (3), and an annular spray pipe (4) is arranged in the sudden expansion mouth.The molten slag that is come by combustion chamber (1) flows down through microstome (12), because aperture (12) is little, makes the radiation of burner hearth heat loss little, helps improving effective swept volume of combustion chamber like this.(12) are adherent through the hole flows for slag, because the slag-drip opening inwall is covered with one deck insulating refractory, improved the temperature of cinder notch inwall, increased the flowability of slag.Insulating refractory can form with alumina cement and bauxites aggregate cast.For guaranteeing that slag-drip opening place slag does not freeze, and is designed to the adherent mobile distance of slag the shortest.Because slag-drip opening is made sudden expansion shape, slag is flowed for outstanding in sudden expansion place, prevented that slag from condensing, piling up and resulting in blockage on slag-drip opening.One annular spray pipe (4) is set in the sudden expansion mouth, and the water jet direction makes slag extinguishing granulation in early days like this shown in (C) among the figure, causes freezing in order to avoid outstanding stream distance is long.The slag of preliminary granulation and the slag that also has little time granulation fall into granulation water tank (6); two additional water pipes (5) are set under the granulation water tank horizontal plane; the water surface temperature that guarantees the granulation water tank is below 50 ℃, in order to avoid there is too much water vapour to produce in the granulation extinguishing process, it is unfavorable to be worked in the combustion chamber.It is stable to guarantee the granulation cistern water level that overflow baffle (7) is set in the water tank; unnecessary water is through overflow baffle (7); flow into overflow pipe; installing one section withstand voltage transparent pipe (8) on the overflow pipe; be used for monitoring that the lime-ash cistern water level is stable; and, judge the combustion case of fired coal combustion chamber according to the muddy degree of overflow water.The slag that falls into the granulation water tank enters the action that pressure-bearing jar (9) has passed through the ball valve (11) of sealing load effect; outside transformation jar (10) discharge system; realize the continuous discharging slag under the pressure condition, transformation jar (10) is provided with overflow valve (13) and vent valve (14).
Compared with the prior art the present invention has the following advantages:
1, the radiation heat loss is little, and the effective swept volume in combustion chamber is big.
2, owing to adopted the slag-drip opening of sudden expansion structure, slag-drip opening can not stop up has realized the continuous discharging slag under the pressure.
3, owing to adopted the secondary extinguishing and replenished water pipe, the water tank surface temperature is lower than 50 ℃, and the granulation quality improves, and water vapour reduces.
Accompanying drawing is a coal-fired pressurized firing chamber slag tap schematic representation of apparatus.
Embodiment: orifice diameter is that this device of 80 millimeters is installed on the testing equipment of MHD generating fired coal combustion chamber (the combustion chamber internal diameter is 330 millimeters) through tens times actual motions; and (the referring to chilling process) starting that stands inclement condition is repeatedly stopped and the accident blowing out; slag-drip opening is still unimpeded; prove that this device performance is reliable; work is convenient, and the slag granulation is even.This slag tap technique device is not only applicable to MHD generating fired coal combustion chamber, and is applicable to other slag tap pressurized firing chamber or coal gasifier.
