Embodiment

Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings.Below by The embodiment being described with reference to the drawings is exemplary, it is intended to for explaining the utility model, and it is not intended that new to this practicality The limitation of type.

In description of the present utility model, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", " length ", " width Degree ", " thickness ", " on ", " under ", "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outer ", " axle To ", " radial direction ", the orientation of the instruction such as " circumference " or position relationship be based on orientation shown in the drawings or position relationship, be only for It is easy to description the utility model and simplifies describe, rather than to indicate or imply that signified device or element must have specific Orientation, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.

At present, china natural resources and environmental problem are increasingly serious, and some high energy consumption industry exigences carry out efficient, energy-conservation Combustion technology.Regenerative combustion technology is promoted in China since the nineties in last century, and it has flue gas waste heat recovery Efficiently, air and gas preheating temperature be high, the low advantage of discharged nitrous oxides, thus regenerative combustion technology glass, The industries such as cement, metallurgy are applied and developed.

Although China's regenerative combustion technology achieves certain technological achievement and economic benefit, there are still Deficiency, most important of which is exactly some the gas bias current problem in regenerator.In regenerator heat exchanging process approximately as： Smoke evacuation stage, flue gas flows through after heat storage and sensible heat is stored in heat storage, heat storage body；In combustion phases, air (or Coal gas) it is heated when flowing through heat storage, in waste heat is melted down by band again.In heat exchanging process, if gas occurs in stove Bias current, on the one hand, be easily caused heat storage localized hyperthermia after commutating several times and produce thermal stress, if the heat produced should Power beyond its bear the limit when will rupture；On the other hand, gas is evenly distributed, and degree is higher, and heat storage is got over can be sufficiently Heat exchange is participated in, gas preheating temperature is higher, and flue gas is lower from accumulation of heat room temperature.

Regenerator in correlation technique undertakes the weight of top checker brick using bearer arch brick structure, and bearer arch structure is by stove Bar arch and skew block composition, have the disadvantage that：1) bearer arch is complicated, and maintenance is difficult after damage.2) coal gas, air from Regenerator bottom enters heat storage by bearer arch, and air flow method is uneven, and accumulation of heat effect is poor.3) limited by bearer arch structure, The design of the size and combination of monolithic heat storage also has certain limitation.

Therefore, the utility model proposes a kind of regenerator, the simple in construction of the regenerator, service life length, maintenance cost It is low, Biased flow phenomenon can be prevented.

First below the regenerator 100 according to the utility model embodiment is specifically described with reference to accompanying drawing.
