Description

Sulfur furnace and its hot line pipe method for maintaining
Technical field
The present invention relates to equipment Repairing Technology field more particularly to a kind of sulfur furnace and its hot line pipe method for maintaining.
Background technology
The sulfuric acid production line of acid production with sulphur includes sulfur furnace, and production process is that Molten sulphur sprays into sulfur furnace by spraying sulphur rifle It burns combustion of sulfur and changes into sulfur dioxide.Sulfur furnace shell is made of carbon steel, inner lining refractory block and insulating brick, in normal course of operation Its temperature is at 1000 degree or so, while hot line pipe, valve with being connected among sulfur furnace and waste heat boiler all take steel shell Inner lining refractory structure.In use, inner lining refractory crack can inevitably occurs, drop or locally damage It is bad.If handle not in time, will cause steel shell because unable to bear high temperature due to burn, at that time reprocessing will bother very much.Tradition is repaiied Skill of returning to work is that first production line stops, then by cooling down to after possessing execution conditions, it is internal to occurring by being manually entered The flame retardant coating of problem is repaired.The renovation technique, which stops work to cool down and construct, needs long in time limit, the construction of usually 24~30 days Phase, and technical difficulty is big, it is high that service personnel's level of skill is required.
The content of the invention
The technical problem to be solved by the present invention is to:A kind of sulfur furnace that can save the duration and its hot line pipe repair side are provided Method.
In order to solve the above problem the technical solution adopted is that:Sulfur furnace and its hot line pipe method for maintaining comprise the following steps:
A, repairing lid is made, repairing lid includes repairing cover panel and is connected around repairing cover panel one week and with repairing cover panel Repairing lid margin plate, repair cover panel on be provided with sprue gate;
B, cover the leak source of equipment to be repaired with repairing, repairing lid margin plate be bonded with equipment to be repaired, repair cover and Cast chamber is formed between equipment to be repaired;
C, refractory cement is poured into cast chamber and full of cast chamber from sprue gate, closure leakage is formed after refractory cement condensation The flame-proof mending layer of point.
It is further:Repairing lid is made of 304 stainless sheet steels of 3mm~5mm.
It is further:The distance for repairing cover panel and equipment to be repaired is 70mm~100mm.
It is further:Mouth-shaped is poured into a mould as square, length of side 200mm.
It is further:In step B, support plate is provided between repairing lid and equipment to be repaired.
The beneficial effects of the invention are as follows:It is carried out maintenance outside sulfur furnace furnace body or hot line pipe, cooling requirement reduces, required Time greatly shortens;Operating personnel operate outside stove or outside hot line pipe, and operation difficulty lowers significantly, beneficial to shorten the operating time and Reduce repairing cost;Therefore the present invention can greatly shorten sulfur furnace and its hot line pipe maintenance time and maintenance cost, greatly shorten Sulfur furnace downtime period.
Description of the drawings
Fig. 1 is sulfur furnace and its hot line pipe method for maintaining schematic diagram;
In figure mark for:Repair lid 1, repairing cover panel 11, repairing lid margin plate 12, sprue gate 13, flame-proof mending layer 2, Support plate 3, equipment to be repaired 4, leak source 41.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
Sulfur furnace and its hot line pipe method for maintaining comprise the following steps:A, repairing lid 1 is made, repairing lid 1 includes repairing and covers Panel 11 and the repairing lid margin plate 12 being connected around repairing cover panel 11 1 weeks and with repairing cover panel 11, on repairing cover panel 11 Sprue gate 13 after setting;B, the leak source 41 of equipment 4 to be repaired is covered with repairing lid 1, repairing lid margin plate 12 is set with to be repaired Standby 4 fitting, repairs and cast chamber 5 is formed between lid 1 and equipment to be repaired 4;C, refractory cement is poured into cast from sprue gate 13 Chamber 5 is simultaneously full of cast chamber 5, and the flame-proof mending layer 2 of closure leak source 41 is formed after refractory cement condensation.Wherein, equipment 4 to be repaired is Refer to sulfur furnace furnace body or sulfur furnace hot line pipe.
The present invention carries out maintenance outside sulfur furnace furnace body or hot line pipe, and cooling requirement reduces, and required time greatly shortens; Operating personnel operate outside stove or outside hot line pipe, and operation difficulty lowers significantly.Flame-proof mending layer 2 plays heat-insulation and heat-preservation work after repair With refractory cement refractory temperature disclosure satisfy that requirement at 1000 DEG C or more.
Repairing lid 1 is made of 304 stainless sheet steels of 3mm~5mm.304 stainless steel steel heat resisting temperatures are 800 DEG C~900 DEG C, even if when long-time service flame-proof mending layer 2 comes off, sulfur furnace furnace body or sulfur furnace hot line pipe can also be avoided to leak.
It repairs cover panel 11 and the distance of equipment 4 to be repaired is promoted as 70mm~100mm.Repair cover panel 11 with it is to be repaired The distance of equipment 4 defines the thickness of flame-proof mending layer 2, and 2 thickness of flame-proof mending layer is rational for 70mm~100mm.It can be It repairs and support plate 3 is set between lid 1 and equipment to be repaired 4, cause 2 local thickness of flame-proof mending layer to avoid the repairing deformation of lid 1 Not in the reasonable scope.
13 shape of sprue gate is to be recommended as square, length of side 200mm.
