Abstract

The utility model relates to an energy-conservation cooling device that can recover waste heat of industrial kiln and furnace and be convenient to vibrate and remove chimney ashes. A cooling casing of the device can wrap one or a plurality of chimneys; a cylindrical body is arranged into an interlayer between the chimney and the cooling casing, one end of the cylindrical body contacts with the chimney wall, and the other end is fixed to the cooling casing and sealed and forms a vibration point, which can be mechanically or manually vibrated to remove ashes in the chimney. Moreover, cooling medium in the cooling casing can cool down high temperature smoke and gas in the chimney through heat conducting, thus recovering the waste heat of the chimney and achieving the target of facilitating the production and energy conservation and reducing consumption.

Description

The stove flue waste heat recovery plant of band rapping post

Technical field

The recovery that the utility model relates to a kind of flue used heat of industrial furnace makes things convenient for simultaneously the device of ash discharge again.

Background technology

At present, the used heat of general large-scale industrial furnace is reclaimed by waste heat boiler, and the used heat of middle-size and small-size industrial furnace is then wasted by the natural air cooling of flue surface.Once there was factory outside the flue of stove, to put the layer of metal pipeline again, pass to media such as water or air in the interlayer, reclaim flue used heat, reduce the temperature of flue gas in the flue, cigarette ash influence is ventilated but internal layer flue inner tubal wall bonds easily, every one deck cooling jacket can't rapping flue ash discharge thereby be forced to cancel cooling jacket.

Summary of the invention

For overcoming the problem that existing middle-size and small-size industrial furnace is difficult to reclaim used heat, the utility model provides a kind of device, and this energy-conserving cooling device can not only reclaim the used heat of stove, and can implement the rapping flue, makes things convenient for the flue ash discharge.

The technical scheme that its technical problem that solves the utility model adopts is: the flue overcoat last layer cooling jacket at stove, pass to media such as water or air in the interlayer of flue outer wall and cooling jacket, and reclaim the used heat of flue gas in the flue, reduce the temperature of flue gas; Between the interlayer of flue outer wall and cooling jacket, with a column, an end closely contacts with walling of flue simultaneously, and the other end is fixed on the cooling jacket and sealing.This fixing point promptly forms the rapping point.Can around cooling jacket, implement mechanical vibrator or artificial rapping.

The rapping position that flue should be arranged sufficient amount is when guaranteeing rapping, and the cigarette ash that bonds on the flue is shaken drops down onto ash discharging gear.Cooling jacket both can wrap up single flue, can wrap up many flues again.

The beneficial effects of the utility model are: can effectively reduce the temperature of flue gas in the flue, when reclaiming used heat, make things convenient for flue rapping ash discharge.Only need to install between cooling jacket and flue the rapping post of sufficient amount, simple in structure, easy to make, expense is cheap.

Description of drawings:

The utility model is described in further detail below in conjunction with accompanying drawing.

The stove flue waste heat recovery plant schematic diagram of Fig. 1 band rapping post

The stove flue waste heat recovery plant A-A partial longitudinal section of Fig. 2 band rapping post

Among the figure 1, flue gas, 2, cooling medium (water or air) 3, rapping post 4, flue

5, cooling jacket 6, walling of flue 7, cooling jacket wall

The specific embodiment

In Fig. 1, kiln gas (1) enters from flue (4) one ends, the other end comes out, cooling jacket (5) is with single or many flue parcels, on cooling jacket with flue corresponding position perforate, column is put in, contact with the flue of the inside, column outer end and cooling jacket are fixed and are sealed.This fixedly column promptly as the rapping post (3) of mechanical vibrator or artificial rapping.

Cooling jacket has the import and the outlet of cooling medium (2), and cooling medium can be water or air.

In Fig. 2, the heat of kiln gas (1) is passed to cooling medium (2) in the interlayer by walling of flue (6), can be utilized after the cooling medium heat absorption.Rapping post (3) passes cooling jacket wall (7), and an end is fixed on the cooling jacket wall, and the other end contacts with flue.By the rapping post on the rapping cooling jacket outside, the rapping post is delivered to flue with the rapping energy, and the cigarette ash that bonds on the flue will be shaken drops down onto ash discharging gear.

If cooling medium is a water, then the water after the heating can be made domestic water or other purposes;

If cooling medium is an air, then the air after the heating can return to kiln etc. and implement the hot blast air blast, and fuel savings also can heat, dry other object.

Claims

1. the stove flue waste heat recovery plant with the rapping post between the interlayer of flue and cooling jacket, has the column that transmits the rapping energy, and it is characterized in that: column one end contacts with walling of flue, and the other end and cooling jacket are fixed and sealed.
