Abstract

The utility model discloses a kind of blast furnace gas dust sampling device, comprise sample valve group and dust filter unit, the sample valve group is by gas admittance valve, sample valve, sampler barrel, nitrogen valve, air outlet valve is formed, dust filter unit is by articulation, stopple coupon, dust filtration bag constitutes, one end of gas admittance valve is connected with the blast furnace gas trunk line, the other end is connected with nitrogen valve with sample valve, sample valve is connected with an end of stopple coupon by articulation, the other end of stopple coupon is with dust filtration bag, after dust filtration bag is inserted in sampler barrel, stopple coupon pass through with ring flange dock with the flanged dish of sampler barrel and be tightly connected, the other end of sampler barrel is connected with air outlet valve.Because the dust filtration bag of this device can adopt high temperature high-pressure resistant material to make, cloth bag is cracky not, can make gas and dust sample measure precision and effectively improve, gas poisoning that gas leakage causes in the time of also can effectively preventing to take a sample simultaneously and the high temperature accident of burning takes place.

Description

A kind of blast furnace gas dust sampling device
Technical field
The utility model relates to a kind of blast furnace gas dust sampling device.
Background technology
Blast furnace gas is an important gaseous state energy medium of following the blast furnace ironmaking production run to produce, and it has High Temperature High Pressure and big characteristics of dust.For make pressure that blast furnace gas carries can and chemical energy is utilized effectively and for the design of dedusting of blast furnace gas system provides the dust content data, must carry out sampling and measuring to the dust concentration of blast furnace gas.In the prior art,, adopt the overanxious sampling detection method of filter paper usually to the sampling and measuring of blast furnace gas, but since abominable factor affecting such as the high temperature high pressure and hig flow speed of blast furnace gas adopt this method filter paper charing or breakage often to occur, and cause following problem:
1, dust sampling is difficult and untrue, causes error at measurment to increase, and can not truly reflect the dust content of blast furnace gas system.
2, sampling the time is difficult to reach the coal gas seal request, has gas leak, easily causes operating personnel that gas poisoning takes place and high temperature is burnt, and is unfavorable for safety in production.
Summary of the invention
For effectively overcoming the big and unsafe problem of staff of the error that adopts the overanxious sampling detection method of filter paper to occur, the present invention proposes following technical solution, makes the purpose that blast furnace gas sampling and measuring handling safety is reliable, increase substantially its sampling and measuring precision to reach.(satisfy ironmaking production and the production run control requirement of gas washing system, guarantee coal gas processing quality, it is fixing, flexible that the utility model adopts, cloth bag blast furnace gas dust content sampler with better sealing is realized the accurate sampling operation of blast furnace gas dust content before and after gas washing or the dry dust removal system.)
A kind of blast furnace gas dust sampling device, comprise sample valve group and dust filter unit, it is characterized in that: described sample valve group is by gas admittance valve 1, sample valve 2, the sampler barrel 7 of flanged dish 6, nitrogen valve 8, air outlet valve 9 is formed, described dust filter unit is by articulation 3, the stopple coupon 4 of flanged dish 6, dust filtration bag 5 constitutes, one end of gas admittance valve 1 is connected with the blast furnace gas trunk line, the other end is connected with nitrogen valve 8 with sample valve 2, sample valve 2 is connected with an end of stopple coupon 4 by articulation 3, the other end of stopple coupon 4 is with dust filtration bag 5, after dust filtration bag 5 is inserted in sampler barrel 7, stopple coupon 4 pass through with 7 flanged dishes 6 of ring flange 6 and sampler barrel dock and be tightly connected, the other end of sampler barrel 7 is connected with air outlet valve 9, and the other end of air outlet valve 9 is connected with the low-pressure gas pipe network.
Described dust filter unit is detachable, after blast furnace gas dust sampling operation is finished, opens nitrogen valve 8, unloads after making stopple coupon 4 purge cooling, takes out dust filtration bag 5, can realize the collecting and sampling of gas dust.
Because the dust filtration bag of this device can adopt high temperature high-pressure resistant material to make, cloth bag is cracky not, and the Dust Capacity that dust filter unit is collected is more genuine and believable, and gas and dust sample is measured precision and effectively improved; Again since this device at each position good seal of when sampling, no cracky parts, and the employing nitrogen purging cools, and can prevent effectively that the sampling operation personnel from burning because of gas leakage causes gas poisoning and high temperature.
Description of drawings
Accompanying drawing is the connection diagram of blast furnace gas dust sampling device.
Among the figure: 1 is admission valve, and 2 is sample valve, and 3 are articulation, and 4 is stopple coupon, and 5 is dust filtration bag, and 6 is ring flange, and 7 is sampler barrel, and 8 is nitrogen valve, and 9 is outlet valve.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
A kind of blast furnace gas dust sampling device, comprise sample valve group and dust filter unit, it is characterized in that: described sample valve group is by gas admittance valve 1, sample valve 2, the sampler barrel 7 of flanged dish 6, nitrogen valve 8, air outlet valve 9 is formed, described dust filter unit is by articulation 3, the stopple coupon 4 of flanged dish 6, dust filtration bag 5 constitutes, one end of gas admittance valve 1 is connected with the blast furnace gas trunk line, the other end is connected with nitrogen valve 8 with sample valve 2, sample valve 2 is connected with an end of stopple coupon 4 by articulation 3, the other end of stopple coupon 4 is with dust filtration bag 5, after dust filtration bag 5 is inserted in sampler barrel 7, stopple coupon 4 pass through with 7 flanged dishes 6 of ring flange 6 and sampler barrel dock and be tightly connected, the other end of sampler barrel 7 is connected with air outlet valve 9, and the other end of air outlet valve 9 is connected with the low-pressure gas pipe network.
When carrying out the dust sampling operation, the first step: dust filtration bag 5 is fixed on the stopple coupon 4; Second step: close admission valve 1, then stopple coupon 4 is connected with sample valve 2 outlets with sampler barrel 7; The 3rd step: close outlet valve 9, open sample valve 2, slowly open nitrogen valve 8 again, censored sample device sealing; The 4th step: close nitrogen valve 8, open outlet valve 9, slowly open admission valve 1 again, flow through a certain amount of coal gas by standard-required; The 5th step: close admission valve 1, open nitrogen valve 8, device is purged, treat that device temperature and gas content are reduced to when human body do not had injury, unload stopple coupon 4, take out dust filtration bag 5, carry out dust collection and analysis.
