The coal pit body comprises a pit head, a pit body and a pit tail, wherein the pit body is used for firing a product; the kit tail is provided with a quenching air tube and used for cooling the product; the pit tail is provided with an air guide device which is communicated with the quenching air tube; the air guide device can be used for blowing quenching air to the product to form two vertical air curtains. The coal pit body disclosed by the utility model can be used for reducing the influence of high-temperature smoke to a cooling effect of the product, so that the cooling efficiency is high.
Description
Technical field
The utility model relates to the kiln body, particularly a kind of coal pit kiln body.
Background technology
As everyone knows, most kiln body is divided into preheating section, and the section of burning till and cooling section in the process of burnt product, can produce a large amount of high-temperature flue gas, and particularly at cooling section, high-temperature flue gas has a strong impact on cooling effect, also causes the waste of the energy.
The utility model content
The utility model proposes a kind of coal pit kiln body, solved that in prior art, high-temperature flue gas has a strong impact on cooling effect, also cause the problem of the waste of the energy.
The technical solution of the utility model is achieved in that
The utility model discloses a kind of coal pit kiln body, comprise kiln hood, be used for burnt product the kiln body, have the kiln tail that is used for refrigerated product of chilling airduct, it is characterized in that: described kiln tail has the air ducting that communicates with described chilling airduct, described air ducting can make the chilling wind to goods, forms the two vertical air curtains in road.
Preferably, described air ducting comprises wind guide tank, and described wind guide tank has rectangular air guide hole.
Preferably, described kiln body comprises steel construction and refractory material two parts, and described steel construction uses square hollow section steel through the framework that is welded, and inlays steel plate with baking paint kiln body in framework again, and described refractory material all is contained within steel construction.
Preferably, described refractory material comprises:
Lightweight corundum-mullite, light-weight mullite brick, Poly Light High Aluminum Firebrick or light weight fireclay brick.
Preferably, described kiln hood has at least one exhaust opening.
Preferably, described chilling airduct is connected with the chilling blower fan, and the suction inlet of described chilling blower fan is established air filter.
Implement a kind of coal pit kiln body of the present utility model, have following useful technique effect:
The two vertical air curtains in road of chilling wind are arranged at the section of burning till latter end chilling front end, the cold wind that this air curtain blasts can prevent that flue gas from flowing backwards, chilling wind is established two exhaust outlets of Yao Qiang both sides setting cold wind is directly squeezed under kiln top and refractory slab, both made product sharply cooling, prevented again that cold wind from directly blowing to product and causing the product bursting by freezing.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is a kind of coal pit kiln of the utility model body structure schematic diagram.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
See also Fig. 1, embodiment of the present utility model, a kind of coal pit kiln body, comprise: kiln hood 1, be used for burnt product kiln body 2, have the kiln tail 3 that is used for refrigerated product of chilling airduct 6, kiln tail 3 has the air ducting 7 that communicates with chilling airduct 6, air ducting 7 can make the chilling wind to goods, forms the two vertical air curtains in road
As shown by the arrows in Figure 1.
Wherein, air ducting 7 comprises wind guide tank, and described wind guide tank has rectangular air guide hole.
Kiln hood 1 has at least one exhaust opening 11.
The below is elaborated:
The kiln body comprises steel construction and refractory material two parts, and the kiln steel structure frame uses square hollow section steel through strictly examining
The processing technology of studying carefully is welded, and inlays steel plate with baking paint in framework again.Kiln body refractory material all is contained within steel construction, and liner fireproof material is different according to the temperature height, uses respectively lightweight corundum-mullite, light-weight mullite brick, Poly Light High Aluminum Firebrick, light weight fireclay brick etc., and the kiln outer wall uses the good calcium silicate board of heat-proof quality.Due to the section of burning till 21 temperature more than 1350 ℃, the nozzle of the high fiery soaking zone of the section of burning till 21 on every side and the section of burning till high temperature section has 30mm Yao Qiang, kiln pushes up and is lightweight corundum-mullite brick, the thick zirconium tapetum fibrosum that contains of two layers of 50mm of kiln car face paving, other insulation materials of kiln such as high-alumina brick, clay brick, clay fire clay, Poly Light High Aluminum Firebrick etc. all use Xinmi City's product.
In kiln, flue gas imports smoke evacuation through kiln hood 1 crown section and several groups of bottoms exhaust opening, branch flue, main chimney flue
Blower fan directly enters atmosphere by air-introduced machine.
The gas stove top waste heat recovery.Increase waste heat recovery jacket at furnace roof, recycle waste heat, recycling.
Cooling system comprises chilling airduct 6 and cooling line, and the outer cold wind of kiln is directly squeezed in kiln from up and down, Yao Qiang both sides aperture by chilling blower fan 5, chilling airduct 6, makes goods realize sharply cooling from 1350 ℃ to 700 ℃.Chilling blower fan 5 suction inlets are established air filter, and blower fan is two, one open one standby.Chilling airduct 6 uses the heat-resistance stainless steel pipe, and the airduct valve is the regulating butterfly valve with scale.For guaranteeing the automatic control of chilling, chilling wind uses a frequency converter automatically to control, the two vertical air curtains in road of chilling wind are arranged at the section of burning till latter end chilling front end, the cold wind that this air curtain blasts can prevent that flue gas from flowing backwards, chilling wind is established two exhaust outlets of Yao Qiang both sides setting cold wind is directly squeezed under kiln top and refractory slab, both made product sharply cooling, prevented again that cold wind from directly blowing to product and causing the product bursting by freezing.
The transformation of ash-pan slag-tapping system improves the ash-pan radian, and it is evenly slagged tap, and at the uniform velocity advances coal, and coal is abundant
Be utilized.
