Abstract
The utility model provides a kind of energy-conservation refractory brick, the middle part of brick body both sides is respectively arranged with an inclined-plane, two described inclined-planes are parallel, the upper intersection of two described inclined-planes and brick body side surface and the top edge line parallel of brick body, the lower intersection of two described inclined-planes and brick body side surface and the lower limb line parallel of brick body, the angle of described inclined-plane and brick body side surface is 30-60 °; Described brick body one end is the fire-resistant portion other end is insulation portion.This energy-conservation firebrick structure is simple, reasonable, compact, and between adjacent segments ability firebrick, occlusion rationally, not easily loosening and damaged; Have fire-resistant and insulation two kinds of functions concurrently, be applicable to circulating fluidized bed combustor.
Description
Technical field
The utility model relates to resistance to ignition technique, particularly relates to a kind of energy-conservation refractory brick.
Background technology
Current CFBB is on the market by combustion chamber and air compartment composition, the outer wall of combustion chamber is disposed with flame retardant coating and heat-insulation layer, flame retardant coating and heat-insulation layer layering arrange and cause chamber structure complexity, heat loss serious, substantially increase the operating cost of fluid bed.
In addition, existing refractory brick shape is regular cuboid, and when colding and heat succeed each other, adjacent bricks body expands with heat and contract with cold and easily causes occlusion to loosen; Or support the swollen brick body that causes between brick body and break, have a strong impact on application.
So urgently a kind of refractory brick that not only there is fire-resistant function but also there is heat insulation function, and then simplify recirculating fluidized bed outer wall construction, reduce thermal loss, reduce the operating cost of fluid bed.
Utility model content
The purpose of this utility model is, single for above-mentioned refractory brick purposes, and consume energy serious problem, proposes a kind of energy-conservation refractory brick, and this energy-conservation firebrick structure is simple, reasonable, compact, has fire-resistant and insulation two kinds of functions concurrently.
For achieving the above object, the technical solution adopted in the utility model is: a kind of energy-conservation refractory brick, the middle part of brick body both sides is respectively arranged with an inclined-plane, two described inclined-planes are parallel, the upper intersection of two described inclined-planes and brick body side surface and the top edge line parallel of brick body, the lower intersection of two described inclined-planes and brick body side surface and the lower limb line parallel of brick body, the angle of described inclined-plane and brick body side surface is 30-60 °; Described brick body one end is the fire-resistant portion other end is insulation portion.
Further, described fire-resistant portion is carborundum wear-resistant castable or mullite pouring material.
Further, described insulation portion is heat resistance fiber.
Further, the angle of described inclined-plane and brick body side surface is 45-60 °.
Further, one end more than described energy-conservation refractory brick inclined-plane is insulation portion, and the one end below described energy-conservation refractory brick inclined-plane and inclined-plane is fire-resistant portion.
In order to ensure the working strength of energy-conservation refractory brick, fire-resistant portion and the insulation portion of this brick body are formed in one.
The energy-conservation firebrick structure of the utility model is simple, reasonable, compact, has the following advantages compared with prior art:
(1) occlusion between adjacent two energy-conservation refractory brick is more reasonable, and when there is high temperature and low temperature conversion, inclined-plane occlusion structure not easily changes, and substantially prolongs the service life of energy-conservation refractory brick;
(2) brick body two ends adopt fire-resistant portion and insulation portion respectively, and envoy's ability firebrick has function that is fire-resistant and insulation concurrently;
(3) the energy-conservation refractory brick of the utility model is with the fire-resistant of its excellence and heat-insulating property, is widely used in the association areas such as recirculating fluidized bed.

Detailed description of the invention
Below in conjunction with embodiment, the utility model is further illustrated:
Embodiment 1
As shown in Figure 1, energy-conservation refractory brick disclosed in the present embodiment comprises the brick body that overall configuration is cuboid, the middle part of brick body both sides is respectively arranged with an inclined-plane, two described inclined-planes are parallel, the upper intersection of two described inclined-planes and brick body side surface and the top edge line parallel of brick body, the lower intersection of two described inclined-planes and brick body side surface and the lower limb line parallel of brick body, the angle of described inclined-plane and brick body side surface is 45 °.
Described brick body one end is fire-resistant portion 2 other end is insulation portion 1, and particularly, one end more than described energy-conservation refractory brick inclined-plane is insulation portion 1, and the one end below described energy-conservation refractory brick inclined-plane and inclined-plane is fire-resistant portion 2.The fire-resistant portion 2 that the present embodiment adopts is carborundum wear-resistant castable, and insulation portion 1 is heat resistance fiber.
Refractory brick energy-conservation described in the present embodiment is applied to circulating fluidized bed combustor, and experiment proves that this energy-conservation refractory brick is while the occlusion degree ensured, has excellent fire-resistant and heat-insulating property.
Embodiment 2
The present embodiment substantially the same manner as Example 1 unlike, described in the present embodiment, the fire-resistant portion of energy-conservation refractory brick is mullite pouring material, and the angle of described inclined-plane and brick body side surface is 30 °.
Experiment proves that described in the present embodiment, energy-conservation refractory brick has excellent occlusion degree and fire-resistant, heat-insulating property equally.
Last it is noted that above each embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to foregoing embodiments, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
