Description
Technical field
The invention belongs to boiler matching equipment technical field, be particularly related to a kind of boiler economizer.
Background technology
Economizer is arranged in boiler back end ductwork and utilizes the heat of boiler tail low-temperature flue gas to carry out heating boiler feed water.Water flows from lower to upper in economizer, and flue gas washes away snakelike piping from top to bottom, forms convection heat transfer' heat-transfer by convection, the heat of flue gas is passed to the water in snakelike piping.Because it absorbs the heat of low-temperature flue gas, reduce the exhaust gas temperature of flue gas, save the energy, improve efficiency, so be referred to as economizer.
A mode of hanging for economizer coiled pipe system generally adopts supporting type, and snakelike piping is bearing on backbar by pipe clamp, but this kind of pattern requires that pipe clamp has stronger rigidity, in order to avoid loses stability after pressurized.Therefore the tube bank height of every one-level economizer can not be too high, otherwise pipe clamp rigidity not easily unstability thus cause tube bundle deformation.When restraining excessive height, one-level economizer can only be splitted into two-stage, also must leave corresponding space for maintenance between two-stage tube bank, considerably increase the overall height of economizer thus, boiler is arranged in limited space, and enough economizers are comparatively difficult.For the problems referred to above, need a kind of structure of exploitation badly simple, easy to installation and maintenance, effectively can improve a kind of boiler economizer of pipe clamp rigidity.
Summary of the invention
The object of the invention is to overcome the above-mentioned defect mentioned and deficiency, and a kind of boiler economizer is provided.
The technical scheme that the present invention realizes the employing of its object is as follows.
A kind of boiler economizer, comprises backplate, backbar, pipe clamp and snakelike piping; Described backplate encloses formation flue, and snakelike piping is arranged in flue; Described backbar level frame is located on backplate; Described pipe clamp is vertically fixed on backbar; Described snakelike piping comprises one group of contour setting and the snakelike tube bank be intervally arranged; Described snakelike tube bank is fixed by pipe clamp; Described snakelike piping is equipped with location-plate; Described location-plate next-door neighbour pipe clamp is arranged; Described location-plate wears connection round steel.
Described location-plate is contour is welded in snakelike tube bank, and row of level lined up by described location-plate.
Described snakelike tube bank is equidistantly arranged, the equidistant straight line arrangement of described location-plate level.
The left and right sides that lower two ends fastened by described coiled pipe is equipped with location-plate; The corner of described snakelike piping is provided with location-plate.
Locating sleeve is provided with between adjacent positioned plate; Described locating sleeve and location-plate all wear connection round steel; Connect round steel locating sleeve and location-plate are connected.
The locating sleeve that described connection round steel two ends welding equipment is shorter.
A kind of boiler economizer, also comprise header, described header is fixed on bearing by U bolt; Described bearing settlement is on backplate; Described bearing offers the mounting hole that can pass for U bolt; After described U bolt banding header, two ends are passed mounting hole and are fixed by nut.
Heat-insulation layer is filled with in described backplate.Described heat-insulation layer is made up of insulation material.
Beneficial effect of the present invention is as follows:
1. also being connected with connecting round steel correspondence by the location-plate in the welding of position, every sheet snakelike tube bank top and the bottom, then ensureing pitch between pipe with locating sleeve, making whole snakelike piping define stable frame structure, thus substantially increase pipe clamp rigidity.In the vertical direction, piping gravity passes on pipe clamp the load concentration of snakelike like this piping, and pipe clamp only need support gravity, not by the effect of horizontal force, thus due to tube bundle deformation that the inadequate unstability of pipe clamp rigidity causes when avoiding economizer tube bank excessive height.
2. this device take into account the factor that parts expand with heat and contract with cold: location-plate is adjacent with pipe clamp and do not weld, and both ensure that the gravity of snakelike piping passes on pipe clamp immediately, has guaranteed again the free wxpansion of snakelike piping energy; Economizer header is fixed on bearing by U bolt, and bolt hole is mounting hole, ensure that the free expanding of header.
3., in this kind of economizer, the cross-sectional area connecting round steel and locating sleeve is less, does not almost affect flow of flue gas and dust stratification.
4. adopt the boiler economizer of above structure to solve the difficult problem that enough economizers arranged by boiler in limited space.Fill insulant material in backplate, as flue, eliminates thick and heavy flue furnace wall.
5. this kind of coal economizer structure is simple, and I&M is more convenient.
