Description
Technical field
The utility model belongs to industrial furnace equipment technical field, is specifically related to a kind of sour gas burning furnace castable refractory furnace lining metal anchorage.
Background technology
Sulfur recovery facility is important environmental protecting device, can will contain H
2s, SO
2sour gas form elemental sulfur or form sulfuric acid further by combustion reaction, general sulfur recovery facility adopts Crouse or super Claus Sulfur Recovery Technique, and its most important equipment is sour gas burning furnace.Sour gas burning furnace operating temperature is high, and can reach more than 1400 DEG C, temperature fluctuation is large, sour gas has certain reproducibility, need to make refractory lining, refractory lining generally can adopt refractory brick, plastic refractory or castable refractory, and plastic refractory, castable refractory is because of can arbitrarily moulding, good integrity and apply more and more, consider effect of heat insulation, even if use refractory brick to do refractory lining, also need to make castable refractory or refractory fibre product thermal insulation layer, adopt refractory fibre product, plastic refractory, the furnace linings such as castable refractory all need metal anchorage to be fixed, the metal anchorage of difformity or material also can be used in multilayer lining, there is following problem in common metal anchoring piece: 1, the anchoring piece of usual employing heat resisting steel or stainless steel, as 06Cr
19ni
10, 06Cr
25ni
20deng, sulfur corrosion resistant is poor, from refractory lining damaged and maintenance is removed time visible metal anchorage refractory lining, also can develop corrosion, it can be made service time of about 3 years highly to deteriorate about 50% even more, seriously undermine its anchoring booster action, affect device security long-term operation, 2, examine and replace difficulty is large.The sour gas burning furnace of Long-Time Service is serious by the erosion of sulphur steam, the easy carbonization of metal wallboard, again weld anchor firmware difficulty is very large, and conventional anchors is directly welded on metal wall, can only cut down during replacing, cut point is uneven, generally above in situ can not weld new anchoring piece, the existence of above problem, sour gas burning furnace refractory lining is often damaged, be unfavorable for equipment safety operation, develop a kind of structure simple, easy to use, detachably, operating cost is low, corrosion-resistant, sour gas burning furnace castable refractory furnace lining metal anchorage tool easy to maintenance is of great significance.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provides the sour gas burning furnace castable refractory furnace lining metal anchorage that a kind of structure is simple, easy to use, detachable, operating cost is low, corrosion-resistant, easy to maintenance.
The purpose of this utility model is achieved in that a kind of sour gas burning furnace castable refractory furnace lining metal anchorage, it comprises kiln wall, the upper side of described kiln wall is provided with nut, described nut is connected with anchoring piece, the outer wall of described anchoring piece bottom is provided with the screw thread matched with nut, the middle part of anchoring piece is provided with annular boss, and the outer wall in the middle part of described anchoring piece is socketed with elastomeric pad.
Described nut is connected with kiln wall by the mode of welding, and the minimum wall thickness (MINI W.) of nut is at least 3mm, and the internal diameter of nut is 6-12mm, and the height of nut is 15-30mm.
Described anchoring piece is Titanium or titanium alloy material material products.
Described nut is connected with kiln wall by the mode of welding.
Described anchoring piece is Y type integral structure.
The beneficial effects of the utility model: the utility model in use, the anchoring piece of the Titanium that employing resistance to corrosion is strong or titanium alloy is as main material, and the mode be threaded connection makes anchoring piece be connected with nut, this set is convenient and swift when installing or removing, the labour intensity of workman is little, simultaneously due to Titanium or titanium alloy of poor quality when welding with dissimilar metal material, difficulty is large, time-consumingly to take a lot of work, and the life-span is short, the setting of elastomeric pad be in order to time anchoring piece and nut between connection more tight, more firm, prevent the connection between anchoring piece and nut from occurring gap, the setting of annular boss is to compress elastomeric pad, anchoring piece is contacted completely with elastomeric pad, it is simple that the utility model has structure, easy to use, detachably, operating cost is low, corrosion-resistant, advantage easy to maintenance.
