Abstract

The utility model discloses a quick slag cooler. The quick slag cooler comprises an outer cylinder, an inner cylinder and a plurality of slag guide vanes, wherein a water channel is formed between the outer cylinder and the inner cylinder; the slag guide vanes have W-shaped cross sections, and are distributed on the inner wall of the inner cylinder in a multi-ring manner in the circumference direction of the inner cylinder; a plurality of W-shaped slag guide vanes are arranged on each ring; each W-shaped slag guide vane is provided with a U-shaped flow channel for allowing cooling water to pass through and a plurality of through-holes; two ends of the U-shaped flow channels are communicated with the water channels; the through-holes are formed around the U-shaped flow channels. The quick slag cooler provided by the utility model can increase the contact area between slag and the slag guide vanes, improve the amount of slag lifted by the slag guide vanes, and prolong the slag retention time on the slag guide vanes, thereby improving the slag cooling efficiency.

Description

A kind of quick slag cooler

Technical field

The utility model relates to a kind of boiler bottom slag cooling device, relates in particular to a kind of quick slag cooler.

Background technology

The major function of slag cooler is that the high temperature furnace slag dry method that boiler is discharged is cooling fast, is widely used in the industrial circles such as the energy, environmental protection, metallurgy, petrochemical industry.As China Patent No. " 200620036536.X " discloses a kind of Multiplayer cooling cylinder type cold slag device, its open day is on 01 09th, 2008, its technical scheme be described slag cooler comprise on urceolus, inner core and inner core inwall, install lead slag blade, between urceolus and inner core, be formed with water channel, in inner core, be also provided with big pipe.In actual use, by leading the little water pipe arranging on slag blade, lead slag blade shedding simultaneously slag, can coolingly lead the slag on slag blade, but owing to leading slag blade, be plane structure, and be inclined at inner core inwall, not only causing every, to lead the slag amount that slag blade sheds less, also cause the slag on slag blade less with the contact area of leading slag blade, make the cooling effect of slag still poor.

Utility model content

The purpose of this utility model is to overcome the above-mentioned problems in the prior art, a kind of quick slag cooler is provided, the utility model can increase slag and leads the contact area of slag blade and lead the slag amount that slag blade is shed, extend slag in the time of staying of leading on slag blade, thereby improve the cooling effectiveness of slag.

For achieving the above object, the technical solution adopted in the utility model is as follows:

A kind of quick slag cooler, comprise urceolus, inner core and a plurality of slag blade of leading, between urceolus and inner core, form water channel, it is characterized in that: described in lead slag blade cross section be W shape, and along inner core circumferencial direction, be many rings and be distributed on the inwall of inner core, on every ring, being provided with a plurality of W shapes and leading slag blade, each described W shape is led and on slag blade, is provided with U-shaped runner and a plurality of through hole that Cooling Water passes through, the two ends of described U-shaped runner communicate with water channel, and described a plurality of through holes are arranged on around U-shaped runner.

In described water channel, be provided with a plurality ofly for cutting off the blocking piece of water channel, the quantity of described blocking piece is identical with the number of rings that W shape on inner core inwall is led slag blade, and each blocking piece correspondence is arranged on every ring W shape and leads between the U-shaped runner of slag blade.

The thickness that described W shape is led slag blade is 0.5-1cm.

Employing the utility model has the advantage of:

One, in the utility model, the described slag blade of leading is arranged to W shape structure, and lead W shape the U-shaped runner that in slag blade, setting communicates with water channel, can either increase the slag amount driving while leading slag blade rotation, can extend again slag in the time of staying of leading on slag blade, not only the better effects if of breaing up to slag in inner core, can also, to leading the slag fast cooling on slag blade, be conducive to improve the cooling effectiveness of slag; During to cooling of furnace slag, the slag that W shape is led on slag blade drops in the process of moving upward from through hole, and through hole can be accelerated W shape and lead the inside slag of escorial on slag blade and the rate of heat exchange of U-shaped runner, thereby further improves the cooling effectiveness of slag.

Two, in the utility model, in described water channel, be provided with a plurality of for cutting off the blocking piece of water channel, the quantity of described blocking piece is identical with the number of rings that W shape on inner core inwall is led slag blade, and each blocking piece correspondence is arranged on every ring W shape and leads between the U-shaped runner of slag blade, this structure can improve the speed that cooling water circulates in water channel, is conducive to improve cooling effect.

Three, in the utility model, the thickness that described W shape is led slag blade is less than 0.5cm, not only reduce the cooling effect of U-shaped runner to the slag that drops, also reduce W shape and led the rigidity intensity of slag blade, and the thickness that described W shape is led slag blade is greater than 1cm, cause again the manufacturing cost of slag cooler higher, the thickness that therefore described W shape is led slag blade is set to 0.5-1cm, guaranteeing, under the prerequisite of small size increase slag cooler manufacturing cost, to be conducive to improve the cooling effectiveness of slag.

The specific embodiment

A kind of quick slag cooler, comprise urceolus 1, inner core 2 and a plurality of slag blade of leading, between urceolus 1 and inner core 2, form water channel 4, described cross section of leading slag blade is W shape, and along inner core 2 circumferencial directions, be many rings and be distributed on the inwall of inner core 2, on every ring, being provided with a plurality of W shapes and leading slag blade 3, each described W shape is led and on slag blade 3, is provided with U-shaped runner 6 and a plurality of through hole 5 that Cooling Water passes through, the two ends of described U-shaped runner 6 communicate with water channel 4, and described a plurality of through holes 5 are arranged on around U-shaped runner 6.

In the utility model, because a slag material varies in size, therefore small particles slag preferably can be passed through in the aperture of described through hole 5, and can not pass through bulky grain slag.

In the utility model, in order to guarantee the circulation of cooling water, preferably described water channel 4 interior arrange a plurality of for cutting off the blocking piece 7 of water channel 4, the quantity of described blocking piece 7 is identical with the number of rings that W shape on inner core 2 inwalls is led slag blade 3, it is corresponding that each blocking piece 7 and every ring W shape are led slag blade 3, and each blocking piece 7 correspondence is arranged on every ring W shape and leads between the U-shaped runner 6 of slag blade 3;

In the utility model, the thickness that described W shape is led slag blade 3 both can arrange 0.5cm, also can be set to 1cm, and the thickness that preferred described W shape is led slag blade 3 is set to 0.7cm.
