Abstract

The utility model discloses a novel drum-type slag cooler which comprises an outer barrel, an inner barrel and a plurality of slag guiding vanes, wherein a water channel is formed between the outer barrel and the inner barrel, and a large water pipe is arranged in the inner barrel; the cross section of each slag guiding vane is W-shaped, and the slag guiding vanes are distributed on the inner wall of the inner barrel in multiple rings in the circumferential direction of the inner barrel; a plurality of W-shaped slag guiding vanes are arranged on each ring, a U-shaped flow channel for enabling cooled water to pass through is arranged on each W-shaped slag guiding vane, and two ends of the U-shaped flow channel is communicated with the water channel. The novel drum-type slag cooler can enlarge the contact area of furnace slag and the slag guiding vanes, increases the amount of furnace slag thrown by the slag guiding vanes, and prolongs the standing time of the furnace slag on the slag guiding vanes, so that the cooling efficiency of the slag cooler is improved.

Description

A kind of Novel drum type slag cooler

Technical field

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

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

A kind of Novel drum type slag cooler, comprise urceolus, inner core and a plurality of slag blade of leading, between urceolus and inner core, form water channel, in inner core, be provided with big pipe, 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, be provided with a plurality of W shapes and lead slag blade, each W shape is led on slag blade and is provided with the U-shaped runner that Cooling Water passes through, and the two ends of described U-shaped runner communicate with water channel.

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 quantity that on described every ring, W shape is led slag blade is 12-30.

On the outer wall of described big pipe, be provided with the plane slag blade of leading, and this is planely led slag blade and W shape and leads slag blade and be dislocatedly distributed.

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, the better effects if of breaing up to slag in inner core not only, can also be to leading the slag fast cooling on slag blade, thereby improve the cooling effectiveness of whole slag cooler.

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, if the quantity that on every ring, W shape is led slag blade is less than 12, by causing, the cooling effect of slag is poor, and the quantity that on every ring, W shape is led slag blade is greater than 30, cause again the manufacturing cost of slag cooler higher, therefore the quantity that on every ring, W shape is led slag blade is set to 12-30, slightly increases under the prerequisite of slag cooler manufacturing cost guaranteeing, can improve the cooling effectiveness of whole slag cooler.

Four, in the utility model, be provided with the plane slag blade of leading on the outer wall of described big pipe, and this planely leads slag blade and W shape and lead slag blade and be dislocatedly distributed, this structure can further improve the effect of breaing up of slag.
