Abstract
The utility model discloses a closed air guide plate for blocking ash and slag, belonging to the bottom plate structure of a combustion furnace, namely an air guide device arranged at the bottom of a furnace body. The air guide plate is provided with an ash and slag baffle plate at the bottom of the furnace, the middle of the ash and slag baffle plate is evenly distributed with raised wind columns, and the side ends of the wind columns at the parts protruded out the ash and slag baffle plate are provided with fixed small outlet pipes. When in work, the ash and slag baffle plate is covered with ash and slag, due to ventilation or air suction at the top of the furnace, air naturally enters from air inlets of the wind columns and goes out from air outlets of the small outlet pipes if only the bottom of the furnace is suspended, thus achieving the purpose of gas supplementation. Due to the closed air guide plate for blocking ash and slag designed by matching with a 'gasification combustion furnace' and a 'self-closed ash and slag discharging device', the ash and slag are blocked from falling off downwards, thus solving the problem of pollution, simultaneously the small outlet pipes arranged obliquely can lead to free natural ventilation. Therefore, the closed air guide plate can achieve the contemplated purpose.
Description
Technical field
The utility model relates to the base arrangement of combustion furnace, promptly is arranged on the blower unit of bottom of furnace body, the induced draft plate of a kind of specifically closed retaining ash, slag.
Background technology
General body of heater needs constantly to replenish air in combustion process, so that it is combustion-supporting to utilize airborne oxygen to carry out.For this reason, people are provided with between the fire grate of body of heater and chassis and slag tap air inlet or a blast orifice is set specially, replenish air with artificial bellows or mechanical bellows and implement burning.Yet this original method pollutes the environment, and for the burning of some defective works show very invalid, must add coal or oil carries out combustion-supporting.Therefore, need improve.
Show from the interrelated data retrieval that comprises Chinese patent, have not yet to see free from environmental pollution, the relevant report of the induced draft plate of closed retaining ash, slag.
The utility model content
In order to overcome the vacancy of prior art, the purpose of this utility model is that a kind of cooperation " gasification combustion furnace " and " self-closed type ash discharge, slag device " (patent applied in addition) will be provided, and realizes a kind of closed retaining ash of gravity-flow ventilation that can be freely free from environmental pollution, the induced draft plate of slag.
The technical scheme that its technical problem that solves the utility model adopts is: the induced draft plate of a kind of closed retaining ash, slag, it is characterized in that: a furnace bottom retaining ash, slag plate are arranged, the centre of retaining ash, slag plate is evenly equipped with the wind post of projection, and the wind post is provided with fixedly air-out tubule at the side that protrudes retaining ash, slag plate part.
Described retaining ash, slag plate can be according to the shapes of combustion furnace, do circular, oval shape, square, hexagon and rectangular.
Described retaining ash, slag plate are provided with 4～1200 wind posts.
Described wind column bottom is provided with air inlet, and the top is what seal.
Described each cooperation of wind post is fixed with 1～10 air-out tubule.
Described air-out tubule cooperates with the wind post, and its opening is to declivity, and wherein descending rake angle is 5～43 degree.
Be covered with ash and slag on retaining ash, the slag plate during work because the ventilation or the exhausting of furnace roof, so furnace bottom down as long as unsettled, wind will be naturally enters from air-out tubule outlet air-out from the air inlet of wind post again, thereby reaches the purpose of make-up gas.
The beneficial effects of the utility model are: because the present invention cooperates " gasification combustion furnace " to reach the closed aerofoil that keeps off ash, slag that " self-sealing ash discharge, slag device " designs, at first blocked the pollution problem of falling grey, slag downwards, the oblique air-out tubule of She Zhiing simultaneously, gravity-flow ventilation that again can be freely.Therefore, the utility model can reach the purpose of drafting.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described.
Fig. 1 is a topology view of the present utility model.
Fig. 2 is a partial enlarged view of the present utility model.
1 retaining ash, slag plate among the figure, 2 wind posts, 3 air-out tubules, 4 air inlets, 5 air outlets.
The specific embodiment
Embodiment 1:
See also Fig. 1 and Fig. 2, a furnace bottom retaining ash, slag plate 1 are arranged, the centre of retaining ash, slag plate 1 is evenly equipped with the wind post 2 of projection, and wind post 1 is provided with fixedly air-out tubule 3 at the side that protrudes retaining ash, slag plate 1 part.
Be covered with ash and slag on retaining ash, the slag plate during work, because the ventilation or the exhausting of furnace roof are unsettled under the furnace bottom, wind will be naturally enters from air-out tubule outlet air-out from the air inlet of wind post again, thereby reaches the purpose of make-up gas.
Claims (6)
