Abstract
The utility model discloses a combustion chamber of a water-coal-slurry water-cooled wall gasification furnace. The combustion chamber comprises a shell and an aerogel insulation felt, wherein the aerogel insulation felt is fixed on the inner side of the shell through a screw and nuts, a flat gasket is arranged on a contact face of the aerogel insulation felt and a nut, and the two nuts are matched to the screw. In comparison with the prior art, the aerogel insulation felt, adopted by the utility model, is fixed by the screw and the nuts, is simple in structure and manufacturing method, and is completed in a manufacturer; the aerogel insulation felt has light weight, low cost and good thermal insulation effect, so that the manufacturing cost of the combustion chamber of the water-coal-slurry water-cooled wall gasification furnace is reduced.
Description
Technical field
The utility model relates to the enclosure interior insulation construction of water-coal-slurry water cooled wall gasification furnace combustion chamber, particularly described combustion chamber.
Background technology
At present, the inner lightening casting material that adopts of water-coal-slurry water cooled wall gasification furnace burning chamber shell is incubated, and will beat diameter on burning chamber shell is the pin that φ 8, length are 25mm.There are following two problems in existing lightening casting material insulation: the pin quantity that will beat on (1) burning chamber shell is many, and difficulty is large.(2) complex manufacturing technology and fabrication cycle are long, and cost is high, generally will make at the scene.
Summary of the invention
Technical problem to be solved in the utility model is to provide the simple water-coal-slurry water cooled wall gasification furnace of a kind of making combustion chamber.
For solving above technical problem, the technical solution adopted in the utility model is:
A kind of water-coal-slurry water cooled wall gasification furnace combustion chamber, comprise housing, also comprises the aerogel heat-insulating felt, and this aerogel heat-insulating felt is fixed in the housing inboard by screw rod and nut.
As preferred technical scheme, the contact surface of aerogel heat-insulating felt and nut is provided with flat gasket.
As preferred technical scheme, what with screw rod, coordinate is double nut.
Compared with prior art, the aerogel heat-insulating felt that the utility model adopts adopts screw rod, nut to fix, and its structure and making method are simple, in manufactory, can complete; The aerogel heat-insulating felt is lightweight, cost is low, high insulating effect, has reduced the manufacturing cost of water-coal-slurry water cooled wall gasification furnace combustion chamber.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure, 1-housing, 2-aerogel heat-insulating felt, 3-screw rod, 4-nut, 5-flat gasket.
Embodiment
As shown in Figure 1, a kind of water-coal-slurry water cooled wall gasification furnace combustion chamber, comprise housing 1, also comprises aerogel heat-insulating felt 2, and this aerogel heat-insulating felt 2 is fixed in the housing inboard by screw rod 3 and nut 4.Wherein, aerogel heat-insulating felt 2 is known heat preserving and insulating material, and screw rod 3, nut 4 adopt stainless steel.
As a kind of preferred technical scheme, aerogel heat-insulating felt 2 is provided with flat gasket 5 with the contact surface of nut 4, on the one hand aerogel heat-insulating felt 2 can be securely fixed on housing 1 more, can avoid on the other hand damaging when mounted aerogel heat-insulating felt 2.
As the preferred technical scheme of another kind, what with screw rod 3, coordinate is double nut, with two nuts 4, is anchored on screw rod 3, further improves the fixing reliability of aerogel heat-insulating felt 2 and housing 1.
During concrete enforcement, root a tree name GB/T8175-2008 " equipment and pipe insulation design guide rule " and Practical Project case calculate thickness and the arrangement mode of screw rod 3 on housing 1 of aerogel heat-insulating felt 2, screw rod 3 is welded on housing, aerogel heat-insulating felt 2 is cut into to the size of handled easily, the welding of root a tree name stainless steel screw rod 3 on housing 1 drawn and put punching on aerogel heat-insulating felt 2 again, screw rod 3 is passed to aerogel heat-insulating felt 2, and fixing with stainless steel double nut and flat gasket 5.
The claimed scope of the utility model is not limited to above embodiment; to those skilled in the art; the utility model can have multiple change and variation, all any modifications within spirit of the present utility model and principle, improves and is equal within replacement all should be included in protection domain of the present utility model.
