Description

The air-cooled slag cooler of malleation
Technical field
The utility model relates to the environmental protection-high temperature sludge treatment facility of thermal power plant boiler energy comprehensive utilization of energy, particularly about the air-cooled slag cooler of the malleation of utilizing the continuous discharging slag technology.
Background technology
How the high temperature furnace slag that thermal power plant boiler is discharged is handled is the hard nut to crack of puzzlement steam power plant always; therefore technical foundation is established in comprehensive utilization of energy and environmental protection-high temperature sludge treatment system realization industrialization; form thermal power plant boiler comprehensive utilization of energy and environmental protection-high temperature sludge system manufacturing industry; can promote the using energy source level of China; alleviate the pressure of environmental protection; simultaneously can drive relevant industries such as machining, material, electric elements, form China's new growth engines.Present known high temperature sludge treatment facility: be to adopt the dividing wall type water cooler 1,, tapping temperature is still very high, reach 400-500 ℃, and water consumption is big; 2, be to adopt the water leg ash cooler, effect is bad; 3, be with air-cooled cooling bed,, become lime-ash and fired bed again owing to sent into the higher fallout of phosphorus content; 4, be air-cooled cooling bed,, become lime-ash and fired bed again owing to sent into the higher fallout of phosphorus content; 5, be vertical moving bed cooler, effect still can because device is too high, only be suitable for overfall deslagging cooling; 6, be cement industry chamotte cooler technology maturation, but equipment is huge.As castor formula cooler (oscillatory type, portable, swinging), clinker can be cooled to 100 ℃ from 1250 ℃, but bulky, heavy, grate plate is fragile, operation requires high, drum-type cooling engine efficiency is lower slightly than the former, clinker can be chilled to 200 ℃ from 1200 ℃, auxiliary air can be preheated to 600-700 ℃ and simple in structure, and operation is convenient, power consumption is also little, but device is heavy.
Vertical air-cooled moving bed slag cooler and surface bed fluidized bed slag cooler, cooling effect is all fine, but there is coking phenomenon in the former, there is the big and charging control accent problem of power consumption in the latter, developed a kind of oscillatory type surface bed fluidized bed slag cooler afterwards, but, be difficult to be fit to the instructions for use of factory because of being the negative pressure operation.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, to provide a kind of malleation air-cooled slag cooler, is to use the continuous discharging slag technology, solves the sealing problem of slag cooler.
The technical solution of the utility model realizes in the following manner: the air-cooled slag cooler of malleation, form by slag cooler body, shock mount, slag input system, slag notch, air inlet, air outlet etc., be provided with air distribution plate, scum pipe and high temperature continuous discharging slag device in the slag cooler upper part of body, the middle part is provided with air inlet, vibrating motor and slag notch, bottom and shock mount are fixed, and it is characterized in that: the bottom and the slag notch of described cooler body are provided with oscillating plate.
Above-mentioned oscillating plate becomes constant slope with the slag cooler body and is that porous is arranged on it.
Above-mentioned slag notch can be arranged on right side outlet, upper outlet, left side outlet and the right outlet of slag cooler body.
Above-mentioned slag notch height is not higher than 1000mm.
Adopt the utility model structure, solved high temperature furnace slag discharge, slag cooler sealing and the power consumption of surface bed fluid bed is big and coking problem, can work under positive pressure, the critical technical parameter that can realize is: cold quantity of slag 3-4T/h platform, cold slag temperature is less than 200 ℃, and hot blast temperature is 120 ℃, power consumption 60KW/ platform, energy recovery rate reaches more than 89%, and the dust Control rate reaches 95%.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Know that by Fig. 1 the air-cooled slag cooler of the malleation of present embodiment is made up of slag cooler body 9, shock mount 10, slag input system, slag notch 6, air inlet 4, air outlet 8 etc.The slag input system that is provided with on the top of slag cooler body 9 comprises air distribution plate 1, scum pipe 2, high temperature continuous discharging slag device 3, the middle part is provided with air inlet 4, vibrating motor 5 and slag notch 6, bottom and shock mount 10 are fixing, also be provided with oscillating plate 7 between the bottom of slag cooler body 9 and slag notch 6, oscillating plate 7 and slag cooler body 9 have a gradient, many rounds are arranged on it.Slag notch 6 can be arranged on right side outlet, upper outlet, left side outlet and the right outlet of slag cooler body as required.The height of slag notch 6 can be done suitable adjustment according to field requirement, but is not higher than 1000mm.
The course of work: 850 ℃~950 ℃ high temperature sludges of discharging from (circulation) fluid bed boiler furnace enter high temperature continuous discharging slag device 3 and the controlled batcher of high temperature along slag pipe under the boiler, enter the slag inlet of slag cooler then, in slag cooler, carry out heat exchange with the air of sending into from air distribution plate 1; Slag is great-jump-forward and advances on the bed of oscillating plate 7, cooled slag is discharged from slag notch 6.Tapping temperature is about 150 ℃.Air enters bellows by the road by air-supply vibrating motor 5, and again in porous oscillating plate 7 enters the heat exchange layer of slag cooler body 9, and hot slag is the fluidization pattern and carries out direct contact type heat exchange between gas-solid.Can change tapping temperature and leaving air temp by regulating the air intake flow.Hot blast enters deduster again, purifies the back and is discharged by air-introduced machine.Hot blast can be made coal spread wind and use, or makes burner hearth secondary wind, also can sneak into the boiler main air duct and participate in burning, or directly be sent to boiler back end ductwork and discharge, and its occupation mode can be selected by the user.
