Description
Technical field
The utility model relates to the technical field of structures of boiler, is specifically related to a kind of arrangement of convection superheater.
Background technology
Convection superheater is arranged in convection pass, mainly by convection heat transfer' heat-transfer by convection, from flue gas, absorbs heat, by the arrangement of convection superheater, can be divided into two kinds of rectilinear and horizontals.Rectilinear convection superheater is usually placed in horizontal flue; And horizontal convection superheater is arranged in the convection pass of vertical stratification.The horizontal flue of general large-sized boiler all adopts fin panel casing tube pattern, when superheater coil tubes passes top fin panel casing, need be successively through between the pipe of top fin panel casing, the pitch of superheater coil tubes equals the pitch of top monowall tube, so when arranging many group convection superheaters, the pitch of every group of superheater coil tubes must be identical, and this can have influence on flow of flue gas operating mode, and heat transfer and dust stratification are all had to considerable influence.And the horizontal flue of general miniature boiler adopts heavy boiler setting or the light boiler setting pattern of surrounding thermal insulation, many groups convection superheater of different spacing is all directly hung in top coversheet, and its shortcoming is that horizontal flue surrounding cannot be arranged heating surface.For the problem of above-mentioned two kinds of boiler internals, therefore need a kind of energy variation of brand-new exploitation combination, adapt to the multiple type of furnace, the arrangement of convection superheater easy to installation and maintenance.
Summary of the invention
In order to address the above problem, the utility model adopts following technical scheme:
A kind of arrangement of convection superheater, it comprises horizontal flue, top board and soot blower, described horizontal flue both sides and top layout have fin panel casing, in described horizontal flue, be provided with rectilinear convection superheater, described convection superheater consists of the many groups of superheater coil tubes along row, between described superheater coil tubes, comb plate, comb joint is set, by comb plate, comb joint, fix the spacing of superheater coil tubes, between described top board and top fin panel casing, be provided with backplate, described top board is connected by suspension rod with backplate, described backplate is provided with header support, on described header support, header is housed, between described backplate and top fin panel casing, be welded with sealing device, described superheater coil tubes is provided with piping suspension bracket, the described piping suspension bracket other end is fixedly connected with backplate bottom, the two ends of described superheater coil tubes are connected with header.
Further, described sealing device comprises seal one and seal two, described seal one and backplate welding, described seal two and the welding of top fin panel casing, described seal one and seal two are provided with the mounting hole that can pass for bolt, and described seal one and seal two are bolted.
Further, refractory material and insulation material between described backplate and sealing device, have been built.
Further, in described superheater coil tubes, forward and backward array of pipes is provided with anti-abrasion cover, and described anti-abrasion cover is fixedly connected with by the identical semicircular ring of radius.
The beneficial effects of the utility model are as follows:
1. superheater coil tubes is directly fixedly connected with backplate by piping suspension bracket, and no longer, through top fin panel casing, such structure setting, can change arbitrarily the pitch of every group of superheater coil tubes;
2. outstanding of convection superheater is hung relatively simple for structurely, and I&M is more convenient;
3. hermetically-sealed construction adopts between backplate and top fin panel casing mounting sealing device and between sealing device and backplate, builds the mode that refractory material seals, such hermetically-sealed construction both can prevent boiler operatiopn hourglass cigarette, and leaked ash and leak out, and protected again backplate not to be heated;
4. in the forward and backward array of pipes of superheater coil tubes, anti-abrasion cover is set, when the soot blower of arranging before and after can preventing blows ash, pipe is produced to wearing and tearing, and reduce flue gas to the dust stratification of superheater tube and corrosion;
5. anti-abrasion cover is fixedly connected with by the identical semicircular ring of radius, simple for structure, distinguishes with anti-abrasion cover fixed structure of the prior art;
6. the steel construction of sealing device is partly bolted, and bolt hole is waist-shaped hole, and such structure can guarantee that fin panel casing has enough free expanding, has guaranteed again the sealing of sealing device.
