Description
Technical field
The utility model relates to a kind of blast furnace sampler that the district uses that circles round that detects, and especially a kind of blast furnace full blast air port district's sampler that circles round belongs to smelt and detects the utensil technical field.
Background technology
Understand according to the applicant, blast furnace adopts the briquet replacing coke method of coal injection can save the metallurgical coke resource, reduces the environmental pollution that brings because of coking, therefore has bright development prospect.In the practice, how can reach economic coal injection, improve the substitution rate of coal, must fully understand the combustion case that coal dust circles round and distinguishes before the air port.
When prior art was carried out the air port sampling at small furnace, below the blast 150kPa, wind-warm syndrome was less than 1000 ℃, and the hand sampling operation easier is little.But the district of circling round before the air port during blast furnace ordinary production is in high temperature, high pressure conditions, and equipment is difficult to stop in this zone for a long time, so its air port sampling can only carry out under the damping down state usually, and the result can only obtain the coke data before the static air port.Because blast furnace stops coal injection before damping down, therefore can not get unburned coal powder, can only infer that blast furnace circles round distinguish the combustion efficacy of coal injection before the air port by the unburned coal powder that contains that outer gravitational dust collection ash of stove and coal gas wash down in the gas ash.
The utility model content
The purpose of this utility model is: at the problem that above prior art exists, propose a kind of blast furnace full blast air port that can finish sampling operation under landscape condition endlessly district's sampler that circles round, thereby obtain coke data before the required air port
In order to reach above purpose, blast furnace full blast of the present utility model air port circle round the district sampler comprise arrangement sampling dolly in orbit, described sampling dolly upper support thief rod and dust collection jar, described thief rod is made of the stopple coupon and the peripheral cooling water channel at center, the front end of described stopple coupon is high temperature resistant gauge head, the rear end connects the import of dust collection jar by SCS Air Suction Control Solenoid, and the outlet of described dust collection jar accesses the sample rubber bag by the control magnetic valve of giving vent to anger.
Need to use blast furnace full blast air port to circle round district's sampler when carrying out the air port sampling, along the track sample dolly of keeping forging ahead, make high temperature resistant gauge head stretch into the district of circling round of blast-furnace tuyere, open inlet, outlet control magnetic valve, after the rubber bag expansion, the sampling air-flow enters the dust collection jar through stopple coupon, thereby can finish required sampling under the situation of damping down not.Afterwards, close inlet, outlet and control magnetic valve, Pulverized Coal Combustion Products such as the gas in the district of circling round that can will collect and unburned coal powder are by test gas chamber chemical analysis and physics micro-ore deposit facies analysis, and the grasp coal dust circles round before the air port and distinguishes the incendiary behavioural information.
The utility model can be avoided the danger of hand sampling operation, simplifies procedures, and simultaneously by cooling water channel, improves the work-ing life of gauge head and thief rod, helps the stdn sampling operation, alleviates labor intensity of operating personnel, increases substantially working efficiency.
