Abstract

The utility model discloses a horizontal coal-fired boiler smoke separating wall structure which is widely applied to the field of industrial boilers of horizontal fuel coal organic heat carrier boiler convection heating surfaces. The horizontal coal-fired boiler smoke separating wall structure comprises supporting beams and first smoke separating walls. The supporting beams are fixed on two sides of a convection section of a boiler body steel frame. The first smoke separating walls are arranged on the supporting beams piece by piece to separate convection tubes and enable high-temperature smoke to form a series loop along the convection tubes. The upper portions of the first smoke separating walls are sealed with a roof tube of a boiler. The first smoke separating walls are made of refractory concrete in a casting mode, and two sides of the first smoke separating walls are welded and fixed with the boiler body steel frame through fixing steel angles. Due to the fact that the first smoke separating walls are made of the refractory concrete in the casting mode, the horizontal coal-fired boiler smoke separating wall structure effectively solves the problem that smoke separating walls of a horizontal fuel coal organic heat carrier boiler deform and even fall down when being heated. Therefore, manufacture and installation are convenient, and manufacturing cost of the boiler is reduced.

Description

A kind of horizontal coal-fired boiler brick baffle structure
Technical field
The utility model relates to a kind of horizontal coal-fired boiler, relates in particular to a kind of brick baffle structure for horizontal coal-fired boiler of organic heat carrier.
Background technology
At present, extensive use along with boiler of organic heat carrier, according to horizontal coal-fired boiler of organic heat carrier design feature, arrange convection heating surface at the radiation heating-surface rear portion, convection heating surface is divided into several sections usually, for flue gas is flowed along certain direction, need between each section heating surface, increase brick baffle; Guarantee certain flue gas flow rate, make the effect of heat convection reach best; Traditional brick baffle adopts alloy-steel plate as partition material, but finds after after a while operation, and many partition wall steel plates modification of being heated under hot environment is for a long time arranged, and serious coming off blocks flue; Cause the flue gas short circuit effectively not carry out heat exchange, have a strong impact on normally carrying out of production; Adopt simultaneously steel alloy high as its cost of brick baffle, boiler manufacture cost is increased accordingly, energy-saving and cost-reducing in now fierce market competition, the manufacturing cost that reduces product just can make product more competitive.
The utility model content
The purpose of this utility model is to provide a kind of horizontal coal-fired boiler brick baffle structure, its can install easily and in running flexible type and coming off not, reduce simultaneously the manufacturing cost of boiler, make the boiler can long-time even running.Effectively solved the problem that horizontal coal-fired boiler brick baffle exists in the prior art.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of horizontal coal-fired boiler brick baffle structure, it comprises brace summer and the first brick baffle, described brace summer is fixed in the both sides of boiler body steelframe convection section, described the first brick baffle is arranged on the brace summer piecewise convection bank is separated, make high-temperature flue gas form series loop along tube bank, and the top of described the first brick baffle and the sealing of the roof tube of boiler, wherein, described the first brick baffle is formed by the refractory concrete casting, and the both sides of described the first brick baffle are by fixedly angle steel and boiler steelframe are welded and fixed.
Especially, the radiant section in the described boiler body adopts both sides' coil pipe, also is provided with the second brick baffle between radiant tube and the first convection bank, to prevent the high-temperature flue gas short circuit.
Especially, the top rear side of described the first brick baffle is welded and fixed by sealing channel-section steel and both sides steelframe, adopts refractory concrete cast sealing with position, roof tube boundary.
Especially, described the second brick baffle is formed by the refractory concrete cast.
Especially, the both sides correspondence of described boiler body steelframe convection section is provided with supporting seat, and described brace summer is fixedly welded on the supporting seat.
The beneficial effects of the utility model are that described horizontal coal-fired boiler brick baffle structure compared with prior art has following advantage:
1) brick baffle adopts the refractory concrete cast to form, temperature distortion even the problem that comes off when effectively solving horizontal coal-fired boiler of organic heat carrier brick baffle operation;
2) simple and convenient during fabrication and installation.
3) compare the refractory concrete cost with alloy-steel plate lower, thereby reduce the manufacturing cost of boiler.
Description of drawings
Fig. 1 is the structural representation of the horizontal coal-fired boiler brick baffle structure that provides of the utility model specific embodiment 1;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
See also Fig. 1 to shown in Figure 2, in the present embodiment, a kind of horizontal coal-fired boiler brick baffle structure comprises boiler body and the convection tube of convection section in the boiler body is set, the both sides correspondence of described boiler body steelframe convection section is provided with supporting seat 2, be welded with brace summer 1 on the described supporting seat 2, the first brick baffle 3 that is formed by the refractory concrete cast is set on the described brace summer 1 piecewise, the both sides of described the first brick baffle 3 are by fixedly angle steel 6 and boiler steelframe are welded and fixed, to guarantee that boiler first brick baffle 3 in transportation can not be shifted, collapse, described the first brick baffle 3 separates convection bank, make high-temperature flue gas form series loop along tube bank, and the top rear side of described the first brick baffle 3 is welded and fixed with the both sides steelframe by sealing channel-section steel 4, adopts refractory concrete cast sealing with position, roof tube 5 boundary.
In the present embodiment, because the radiant section in the boiler body adopts both sides' coil pipe, between radiant tube and the first convection bank, also be provided with the second brick baffle 7, to prevent the high-temperature flue gas short circuit.
During assembling, described the second brick baffle 7 is poured into a mould in advance, after radiant section and the first convection section are in place, with its hoisted in position, is fixed on the crossbeam of the bottom steelframe that welding is good in advance; After convection bank is in place, brace summer 1 is placed on supporting seat 2 tops is welded and fixed; The first brick baffle 3 is poured into a mould equally in advance, after beam 1 to be supported is welded and fixed, 3 liftings of the first brick baffle is placed on the top of brace summer 1; To roof tube 5 belows, fixedly angle steel 6 is welded and fixed at both sides and the side steelframe of the first brick baffle 3 again, then will seal channel-section steel 4 and be fixedly welded at rear, the first brick baffle 3 top, and with the refractory concrete cast the first brick baffle 3 and roof tube 5 sealings be got final product at an upper portion thereof.
Above-mentioned horizontal coal-fired boiler brick baffle structure is designed to the refractory concrete cast with the convection section partition wall of boiler body by original alloy-steel plate.Make horizontal coal-fired boiler of organic heat carrier reduce the fault rate of boiler in running, reduce simultaneously the manufacturing cost of boiler.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-mentioned example; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
