In addition, also reduce the processing and the assembly difficulty of water wall, be convenient to guarantee the manufacturing accuracy and the stopping property of water wall; Pipe transient mode on this conical surface can adapt to the various conical surface, guarantees on the whole conical surface, to avoid occurring the excessive situation of band steel part width, to guarantee the wall temperature security of water wall.Thereby can effectively solve the problem that exists in the existing gasifier water-cooling wall technique.
The purpose of the utility model realizes through following technical proposals: a kind of novel gasifier water-cooling wall; Main body is the water wall pipe; Said water wall pipe comprises membrane wall main paragraph bend pipe, awl section bend pipe and wye; Said main paragraph bend pipe is shell and tube circumferentially evenly arranges a week along reaction chamber, constitutes the membrane wall cylindrical shell, and said awl section bend pipe and main paragraph bend pipe fuse through wye.
As a kind of optimal way, be welded into a whole through the sealing of filling band steel between the said water wall pipe.
As further optimal way, the side towards the fire face down bonding of said water wall pipe connects pin and lays refractory materials.
As further optimal way, said water wall pipe comprises be arranged alternately No. one pipe and No. two pipes, and No. one pipe is managed into awl section circumferential arrangement form inwardly with No. two, a pipe and manage for No. two in wye be located at the different positions of boring section.
As a kind of optimal way, be merged into an awl section bend pipe through wye after the bending of said two or more main paragraph bend pipe.
As further optimal way, be merged into an awl section bend pipe through wye after the said adjacent two main paragraph bend pipe bendings.
As a kind of optimal way, awl section bend pipe links to each other with the collection case.
As further optimal way, said collection case is provided with the top and hangs or the steel plate of supported underneath collection case.
The effect of portion parts is following in the utility model:
Wye: connect a main paragraph bend pipe and an awl section bend pipe, and part main paragraph bend pipe is merged into an awl section bend pipe in twos,, adapt to the contraction of conical surface circumference to reduce circumferential pipe number side by side; Make water wall awl section and main paragraph integrated, avoided being connected and assembling of complicacy of awl section and main paragraph.
Compared with prior art; The beneficial effect of the utility model: the novel gasifier water-cooling wall of the utility model adopts shell and tube membrane wall main body and carries out the awl section of pipe combination type based on wye; Make main paragraph integrated, simplified the carbonated drink flow process, saved awl section water wall external connecting pipe road and collection case with the awl section; Avoided being connected of complicacy of awl section and main paragraph, assembling and sealing; Simultaneously; On the conical surface, also guaranteed narrower band steel width all the time; Problems such as the awl section water wall band steel part that possibly occur when having avoided adopting alternate manner is wide; To preventing that the water wall overtemperature from being very favorable, in addition, also avoided the danger that cooling performance worsens when steaming of coil tube type water wall; Its globality and good sealing effect, simultaneously simple and compact for structure, convenient processing and manufacture.
