Abstract
The invention relates to a pluggable fast mounting self-sealing type coal economizer. The pluggable fast mounting self-sealing type coal economizer is composed of at least two coal economizer units of the same structure, and the coal economizer units are connected vertically or linked horizontally. The coal economizer units comprise four sealing steel plates which are arranged symmetrically in a pairwise mode, vertical posts are fixedly installed outside the four sealing steel plates, and supporting beams are installed on the lower portion of the inside of the four sealing steel plates. Coiled pipes are arranged inside the four sealing steel plates. One end of one coiled pipe is located on the upper portion of the outside of the sealing steel plates and is welded to a collecting box, and the other end of the coiled pipe is located on the lower portion of the outside of the sealing steel plates and is connected with the coiled pipe arranged on the lower portion of the inside of the sealing steel plates. The pluggable fast mounting self-sealing type coal economizer has the beneficial effects that a coiled pipe structure is adopted by the coal economizer units, the coiled pipe structure can be in a single-pipe sequence, and a multi-pipe staggered structure can further be adopted; the pluggable male and female groove sealing steel plates are adopted on the site for sealing, and thus installing is easy, disassembling is convenient and the sealing performance is good; a plurality of positioning pin shafts or bolts are adopted inside the two sets of the coal economizer units for fast fixation; the coal economizer units are welded and completed in a factory and are rapidly assembled on the site.
Description
Technical field
The present invention relates to boiler internal workpiece technical field, particularly relate to the self-sealed economizer of a kind of pluggable fast-assembling.
Background technology
Economizer is as one of the important heat transfer component of boiler, and it utilizes the feedwater of the heat heating boiler of the tail flue gas of boiler, and then can reach reduction exhaust gas temperature, improves the effect of boiler efficiency.Because these parts belong to pressure-containing member, its manufacture and installation quality directly affect efficient, the safe operation of boiler.
Common economizer has steel pipe type and cast iron type two kinds, and steel pipe type is exactly the coiled pipe and the header composition that adopt one or more groups, and outside utilizes steelframe, backplate, furnace wall to seal, most in-site installation; Substantially be all in-site installation for cast iron gilled tube economizer, pipe is connected with the on-the-spot bolt of elbow.
Economizer is positioned at boiler back end ductwork, and no matter be steel tube economizer or cast iron gilled tube economizer, its sealing property is particularly important.
Steel tube economizer generally adopts steel guard board structure to seal on the crossbeam of steelframe, has certain gap, be difficult to thoroughly eliminate in the later stage, easily cause air leakage into flue duct between the crossbeam of steelframe and column.Most coiled pipe, backplate, steelframe are all in-site installation in addition, and workload is large, easily causes mass defect.
Summary of the invention
For the weak point existed in the problems referred to above, the invention provides the self-sealed economizer of a kind of pluggable fast-assembling.
For achieving the above object, the invention provides the self-sealed economizer of a kind of pluggable fast-assembling,
At least to be connected with overlying relation by the identical economizer unit of two structures or left-right relation links and forms;
Described economizer unit comprises four blocks of sealing steel plates, and wherein said sealing steel plate is symmetrical arranged between two, outside four blocks of described sealing steel plates, be installed with column, and four pieces of described sealing steel plate lower inside are provided with brace summer;
Coiled pipe, it is inner that it is arranged on four blocks of described sealing steel plates, and one end of described coiled pipe is positioned at described sealing steel plate outer upper and header welding, and the other end of described coiled pipe is positioned at described sealing steel plate outer lower portion and is connected with the coiled pipe of below.
Improve further as the present invention, described brace summer is fixed with pipe clamp, described pipe clamp is stuck on described coiled pipe.
Improve further as the present invention, described coiled pipe is that single tube is along array structure or multitube shifted structure.
Improve further as the present invention, described sealing steel plate is the upper and lower fitted seal of mother-son groove structure.
Improve further as the present invention, outside described sealing steel plate, be enclosed with heat-insulation layer.
Preferred as the present invention, described heat-insulation layer is alumina silicate fiber felt material.
Improve further as the present invention, the column of described column and below is fixed by alignment pin or bolt is connected.
Improve further as the present invention, described coiled pipe is connected by header or pipeline with described coiled pipe.
Beneficial effect of the present invention is: be at least made up of economizer unit more than two; Economizer unit adopts coiled pipe structure, can be the suitable row of single tube, also can adopt multitube shifted structure; The on-the-spot pluggable mother-son groove sealing steel plate that adopts seals, and installation is simple, convenient disassembly, sealing property are excellent; Two groups of economizer unit inside adopt some alignment pin (bolt) to fix fast; Weld in economizer unit factory, on-the-spot rapid-assembling.
