Abstract

The utility model discloses a slag guiding blade for a slag cooler. The slag cooler comprises an outer barrel, an inner barrel and a plurality of slag guiding blades, wherein a water channel is formed between the outer barrel and the inner barrel; the cross section of each slag guiding blade is V-shaped; the slag guiding blades are distributed on the inner wall of the inner barrel in a multi-ring manner in the peripheral direction of the inner barrel; a plurality of V-shaped slag guiding blades are arranged on each ring; a U-shaped runner and a plurality of through holes which are used for allowing cooling water to pass through are formed in each V-shaped slag guiding blade; the two ends of each U-shaped runner are communicated with the water channel; the through holes are formed around the U-shaped runners. The slag guiding blade can enlarge the contact area between slag and the slag guiding blades and slag amount thrown by the slag guiding blades, and prolong the standing time of the slag on the slag guiding blades, thereby improving the cooling efficiency of the slag.

Description

A kind ofly for slag cooler, lead slag blade

Technical field

The utility model relates to a kind of boiler bottom slag cooling device, relates in particular to a kind ofly for slag cooler, to lead slag blade.

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; On the outer wall of described big pipe, be provided with and lead slag blade, described in lead slag blade and be provided with at least one little water 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 be plane structure owing to leading slag blade, and be inclined at inner core inwall, limit by the plane slag blade construction of leading, the slag amount that not only causes slag blade to drive is less, also causes the shed weak effect of slag blade to slag, thereby makes the cooling effect of slag poor.

Utility model content

The purpose of this utility model is to overcome the above-mentioned problems in the prior art, provide a kind of for slag cooler lead slag blade, the utility model can increase leads the slag amount that slag blade is shed, and improves the cooling effect of slag.

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

A kind ofly for slag cooler, lead slag blade, this is led slag blade and is fixedly mounted on inner core inwall, it is characterized in that: described in to lead slag blade be v-shaped structure, V-arrangement is led and on slag blade, is provided with cooling tube and a plurality of through hole, the quantity of described cooling tube is at least two, be separately positioned on V-arrangement and lead the two sides of slag blade, a plurality of through holes are arranged on around cooling tube.

Described V-arrangement is led the bottom rounding off of slag blade.

The thickness that described V-arrangement is led slag blade is 1-1.5cm.

Employing the utility model has the advantage of:

One, in the utility model, the described slag blade of leading is arranged to v-shaped structure, can increase the slag amount driving while leading slag blade rotation, during to cooling of furnace slag, the slag that V-arrangement is led on slag blade drops in the process of moving upward from through hole, through hole not only can be shed slag preferably, can also accelerate V-arrangement and lead the inside slag of escorial on slag blade and the rate of heat exchange of cooling tube, is conducive to improve cooling effect and the cooling velocity of slag.

Two, in the utility model, described V-arrangement is led the bottom rounding off of slag blade, and this is provided with to be beneficial to and strengthens V-arrangement and lead the rigidity intensity of slag blade, thereby extends its service life.

Three, in the utility model, if described V-arrangement is led the thickness of slag blade and is less than 1cm, when slag drops from through hole and the effect of cooling tube generation heat exchange poor, cause the cooling velocity of slag slow, and described V-arrangement is led the thickness of slag blade and is greater than 1.5cm, cause again the manufacturing cost of slag cooler higher, the thickness that therefore described V-arrangement is led slag blade is set to 1-1.5cm, neither can significantly increase the manufacturing cost of slag cooler, be conducive to again improve the cooling effect of slag.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Being labeled as in figure: 1, V-arrangement is led slag blade, 2, cooling tube, 3, through hole.

The specific embodiment

A kind ofly for slag cooler, lead slag blade, this is led slag blade and is fixedly mounted on inner core inwall, the described slag blade of leading is v-shaped structure, preferably V-arrangement is led the bottom rounding off of slag blade 1, and V-arrangement to lead the angle that in slag blade 1, two inclined-planes form be that ，Qi obtuse angle, the obtuse angle number of degrees are 135 °-150 °, described V-arrangement is led and on slag blade 1, is provided with cooling tube 2 and a plurality of through hole 3, the quantity of described cooling tube 2 is at least two, is separately positioned on the two sides that V-arrangement is led slag blade 1, and a plurality of through holes 3 are arranged on around cooling tube 2.

In the utility model, the thickness that described V-arrangement is led slag blade 1 both can be set to 1cm, also can be set to 1.5cm, and the thickness that preferred described V-arrangement is led slag blade 1 is set to 1.2cm.

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 3, and can not pass through bulky grain slag.

Claims

1. for slag cooler, lead slag blade for one kind, this is led slag blade and is fixedly mounted on inner core inwall, it is characterized in that: described in to lead slag blade be v-shaped structure, V-arrangement is led and on slag blade (1), is provided with cooling tube (2) and a plurality of through hole (3), the quantity of described cooling tube (2) is at least two, be separately positioned on V-arrangement and lead the two sides of slag blade (1), a plurality of through holes (3) are arranged on cooling tube (2) around.
