Abstract
The utility model belongs to cut deal welding field, specifically for preheat before the pyrolysis gasification furnace equipment barrel straight weld with weld after the hydrogen frock that disappears. A preheat before the pyrolysis gasification furnace equipment straight weld with weld after the hydrogen frock that disappears, includes that upper end pterygoid lamina both sides evenly open the H shaped steel that has the semicircle orifice, the arc shrouding is taken in the welding of H shaped steel one end, take the arc shrouding on trompil welding gas import take over, the stopper has the cotton of heat preservation in H shaped steel the lower part space in. Barrel transversal joint below is arranged in to the frock, lets in gas combustion and heats. The utility model provides a preheat before the straight weld of pyrolysis gasification furnace equipment barrel with weld after the hydrogen frock that disappears, the shaped steel width can guarantee that it respectively is not less than 3 times of barrel wall thicknesss for the welding seam both sides to heat the width, the weld zone even heating has been guaranteed to treat in being in the semi -closed space of frock and barrel constitution by the heat, frock lower part pad is gone into to keep warm cottonly, has improved heating efficiency and heat utilization efficiency, has practiced thrift the cost.
Description
Technical field
This utility model belongs to cut deal welding field, and before specially a kind of gasification furnace tube straight weld, preheating and postwelding disappear
Hydrogen frock.Specifically by this frock, preferably achieve gasification furnace apparatus cut deal cylinder vertical masonry joint weld preheating and postwelding disappears
Hydrogen is processed, and ensure that preheating and the hydrogen specification that disappears, improves efficiency.
Background technology
Gasification furnace is the visual plant of coal gasification apparatus, and cylinder material is generally 15CrMoR or 14Cr1MoR, and thickness is general
For 58～128mm, barrel diameter is 2800～4200mm.Main alloy element Cr, Mo in such material can significantly improve steel
Brittle property, easily produce brittle microscopic structure, adding that the sufficiently high hydrogen concentration in weld metal zone and certain welding are remaining should
Power collective effect causes delayed crack so that welding point is also easy to produce hydrogen.In order to prevent the generation of brittle tissue and crackle it is necessary to adopt
The Technology Measures of dehydrogenation immediately after taking weld preheating to be welded with.In addition, because device diameters are larger, wall thickness is thicker, preheating
Width must reach code requirement, and requires uniformly to heat.
Content of the invention
The purpose of this utility model is the frock providing a kind of gasification furnace equipment barrel vertical masonry joint weld preheating and postwelding to disappear hydrogen,
This frock can ensure that preheating width meets code requirement, and homogeneous heating, improve combustion gas utilization rate and reduce manufacturing cost.
This utility model adopts the following technical scheme that realization：A kind of gasification furnace equipment barrel vertical masonry joint weld preheating and
Postwelding disappears hydrogen frock, uniformly has the H profile steel of multiple semicircle orifices including upper end wing plate both sides, semicircle orifice is all opened in upper end wing plate
Upper end edge；One end welded bands arc shrouding of H profile steel, perforate welding fuel gas inlet adapter on band arc shrouding.
Further, it is plugged with heat-preservation cotton in H profile steel lower space.
After the completion of shell rolling, vertical masonry joint to be welded is placed in underface, and frock is placed horizontally at below cylinder in H shape, weld seam
It is placed in shaped steel two wing plate middle.Wing plate and band arc shrouding are fitted substantially with outside cylinder in front and back, form semi-enclosed cavity；Shaped steel
The other end opens, with two row's semicircle orifices in front and back wing plate as air intlet；The air hose being connected with source of the gas is enclosed within right side combustion
On gas entrance sleeve, it is passed through combustion gas, burns in semi-enclosed cavity after lighting, heat plug in weld seam, H profile steel web lower space
Upper heat-preservation cotton, is run off from downside with reducing heat.Width of heating can ensure that weld seam both sides are respectively not less than 3 times of cylinder wall thickness, and
Homogeneous heating.Heat is gathered in semi-enclosed cavity substantially, and heat utilization ratio is high.
Between H profile steel wing plate, distance is 400～600mm；
Band arc shrouding radian is consistent by being contacted cylinder radian；
Semicircle orifice arc radius R=5mm, pitch of holes is 200mm；
Fuel gas inlet nozzle dimensions are Φ 13 × 2.
The hydrogen frock the utility model discloses a kind of gasification furnace cut deal vertical masonry joint weld preheating and postwelding disappear, it is to lead to
Cross in the hemi-closure space that H profile steel and one end are formed with cylinder with arc shrouding and be filled with combustion gas, another by both sides semicircle orifice and H profile steel
The air that one end enters makes fuel gas buring so that heat is gathered in semi-enclosed cavity, in addition fills in heat-preservation cotton in the shaped steel of lower end,
Heat is prevented to run off from downside.Ensure that weld seam preheating width and can uniformly heat, and improve heat utilization efficiency, save one-tenth
This.

Specific embodiment
A kind of gasification furnace equipment barrel vertical masonry joint weld preheating and postwelding disappear hydrogen frock, uniformly have including upper end wing plate both sides
The H profile steel 1 of multiple semicircle orifices 5, semicircle orifice is all opened in the upper end edge of upper end wing plate；One end welded bands arc shrouding 2 of H profile steel 1, band
Perforate welding fuel gas inlet adapter 3 on arc shrouding 2；
It is plugged with heat-preservation cotton 4 in H profile steel 1 lower space.
Between H profile steel 1 wing plate, distance is 400～600mm, semicircle orifice 5 arc radius R=5mm, and adjacent pitch of holes is 200mm；
Fuel gas inlet adapter 3 a size of Φ 13 × 2.
