Abstract
The utility model relates to a rotary cold slag removal. The utility model is characterized in that a rotary cylinder forms a double-layer cylinder structure, and a water-cooling casing body is formed between an inner cylinder and an outer cylinder; the interior of the inner cylinder is provided with single back stroke or multi-back stroke cooling water pipe bundles which are distributed uniformly and arranged parallel; the head part of the rotary cylinder is provided with a rotary spiral slag feeding casing, the tail part of the rotary cylinder is provided with a rotary spiral slag discharging casing, and the lower side of the rotary cylinder is provided with a drive motor and a holding supporting roller; the tail part of the rotary cylinder is provided with a cooling water feeding main pipe and a water outlet main pipe which are respectively communicated with the cooling water pipe bundles and the water-cooling casing body. The utility model has the advantages of sufficient slag heat dispersion, good cooling performance, large output force and long service life of the equipment. The utility model is suitable for cooling of the boiler slag.
Description
The utility model belongs to the horizontal slag cooler of the auxiliary equipment of the CFBB of heat enginnering, particularly a kind of efficient surface heat exchanging.
At present, the deslagging temperature of state's internal circulating fluidized-bed boiler is at 800～1000 ℃, in the slag phosphorus content seldom, below 2%.This lime-ash has chemism, and the levigate admixture that can make portland cement uses, and higher value is arranged.Yet current most CFBB is not installed slag cooler, though have certain slag cooler is housed, performance is bad, and lime-ash can not be utilized effectively.The conveying of high-temperature ash is difficulty very, the operating environment inclement condition.Water directly cools off then and has lost chemism behind the lime-ash humidification, has also lost value.Developing novel slag cooler is the problem that domestic thermoelectric industry is badly in need of solution.
The purpose of this utility model is, develops a kind of horizontal rotary slag cooler, utilizes high-temperature ash and the cooling water reverse movement in water-cooled housing and tube bank to carry out exchange heat, reaches the purpose of cold slag.
Swinging slag cooler of the present utility model, by the head dreg-inlet hopper, middle revolving drum, afterbody residue outlet and cooling water water inlet, discharging device are formed, it is characterized in that, revolving drum is the double-layer barrel structure, constitute the water-cooled housing between inner cylinder and the outer cylinder, be provided with the cooling water tube bank of even layout, the single backhaul that is arranged in parallel or many backhauls in inner cylinder, the cooling water tube bank is communicated with at the revolving drum head with the water-cooled housing; The head of revolving drum is equiped with and stretches into the slag input revolving spiral shell of drawing the heat-obtaining lime-ash in the dreg-inlet hopper, the revolving drum afterbody is equiped with the revolving spiral shell of slagging tap of the cooling lime-ash being transported to residue outlet, rotating cylinder is provided with descending grade, be provided with ring gear and drive motors interlock at revolving drum one end, two ends are provided with the supporting carrying roller; Be provided with the cooling water main at the revolving drum afterbody, be communicated with the tube bank of cooling water in the revolving drum, be set with the backwater main at the water inlet main, be communicated with the water-cooled housing of revolving drum, intake main and backwater main and revolving drum junction are provided with movable sealing.
Using method of the present utility model is, connect cooling water earlier, drive revolving drum again, then the lime-ash of 800～1000 ℃ of red-hot temperature is discharged by CFBB, fall in the dreg-inlet hopper by pipeline, hot lime-ash just can enter in the revolving drum automatically, in afterbody rolls flow process, the cooling of dispelling the heat when contacting with cooling water tube bank and water-cooled housing inner tube wall of hot lime-ash, cooled lime-ash is discharged continuously by slag notch, with outside conveyer lime-ash is transported again.
The utility model has the advantages that, adopt revolving structure, lime-ash is mainly dispelled the heat to heat exchange surface by the mode of contact heat release, thermal resistance is little, the heat transfer coefficient height.This heat exchange mode has been avoided because of the lime-ash poor thermal conductivity, and thermal conductivity factor is little, and heat transfer resistance is high and problem that influence is conducted heat.Thereby swinging slag cooler of the present utility model, heat transfer area is little, can save great deal of steel, and cooling performance is good, and it is big to exert oneself.Mainly be to roll to contact between lime-ash and heat-transfer surface, thereby light abrasion, service life of equipment is long.Heat-transfer surface is that tube shell type structure is reasonable, and load performance is good.Owing to be horizontal type structure, device height is little, is convenient to arrange the installation and operation operation at the boiler bottom.The utility model advanced technology, function admirable is a kind of efficient slag cooler, can be designed to large-scale cold slag equipment, and can far control speed governing, be applicable to 35 tons/time above medium-and-large-sized CFBB be equipped with, or be used for the cooling operations of other material.
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the front view of swinging slag cooler;
Fig. 2 is A-A cutaway view of Fig. 1.
As seen from the figure, swinging slag cooler of the present utility model is made up of head dreg-inlet hopper, middle revolving drum, afterbody residue outlet and cooling water water inlet, discharging device, it is characterized in that, revolving drum is the double-layer barrel structure, constitutes the water-cooled housing between inner cylinder 4 and the outer cylinder 3; Be provided with the cooling water tube bank 5 of even layout, the single backhaul that is arranged in parallel or many backhauls in inner cylinder, cooling water tube bank and water-cooled housing are communicated with at the revolving drum head; The head of revolving drum is equiped with and stretches into the slag input revolving spiral shell 2 of drawing the heat-obtaining lime-ash in the dreg-inlet hopper 1, and the revolving drum afterbody is equiped with the revolving spiral shell 6 of slagging tap of the cooling lime-ash being transported to residue outlet 9, and rotating cylinder is provided with descending grade; Be provided with ring gear and drive motors 11 interlocks at revolving drum one end, two ends are provided with supporting carrying roller 10; Be provided with cooling water water inlet main 8 in revolving drum afterbody portion, be communicated with the cooling water tube bank in the revolving drum, be set with backwater main 7 at the water inlet main, be communicated with the water-cooled housing of revolving drum, water inlet main and backwater main and revolving drum junction are provided with movable sealing 12 and 13.
