Description

Cloth bag coal gas dust content detection system
Technical field
The present invention relates to coal gas dust removal technical fields, more particularly to a kind of cloth bag coal gas dust content detection system.
Background technique
Blast furnace gas is the important secondary energy sources of iron and steel enterprise, and dustiness is in 8-12g/m3, so having to pass through dedusting So that it is reduced to 10mg/m3 or less could use, dry-method bag-type dust collecting technique because have gas purification quality it is high, it is water-saving, economize on electricity, The features such as investment cost is low, environmental pollution is small is widely used.
If cloth bag dedusting process because technique or Equipment cause dust removing effects poor, causes in coal gas, dust content height will shadow The problems such as subsequent TRT (or BPRT) blade wear of sound, reduction coal gas user equipment service life, dust pollution.Therefore, cloth bag removes Cloth bag coal gas dust removal effect must be inspected periodically in dirt technical process.Traditional sampling mode is to diffuse inspection platform in bag-type dust Upper coupongs are pricked in gas sampling pipe outlet end, and opening valve makes coal gas is logical to close valve, detection sampling pieces of cloth after a period of time Upper dust accumulation situation.
Because coal gas is directly diffused to sample platform in sampling process, live CO content is high, so sampling personnel must wear Air respiratorresuscitator, and monitoring of more than two people going together.Meanwhile there are myopias by many post employees, wear air respiratorresuscitator When breathing mask in eyeglass on generate fog, cause visual effect poor, cause operating process in there are major safety risks.
Prevent coal gas harm in a kind of coal gas dust content sampling process in conclusion developing, structure is simple, operation is convenient, The system important in inhibiting of high reliablity.
Summary of the invention
The technical problems to be solved by the present invention are: in order to overcome the shortcomings in the prior art, the present invention provides a kind of cloth Bag coal gas dust content detection system.
The present invention solves its technical problem technical solution to be taken: a kind of cloth bag coal gas dust content detection system, packet Including rack, fairlead, delivery pipe and detection components, the fairlead are equipped with valve, and the detection components include upper detection block With lower detection block, the lower detection block is set in the rack, and edge is axially arranged with first through hole in the lower detection block, described to draw Outlet pipe is set to the lower detection block lower end and is connected to the first through hole, and edge is axially arranged with the second through-hole in the upper detection block, The delivery pipe is set to the upper detection block upper end and is connected to second through-hole, and the upper detection block is equipped with for driving State driving device of the detection block close to the lower detection block to make the first through hole be connected to the second through-hole, the upper inspection It surveys and is equipped with asbestos print between block and lower detection block.
Fairlead is used to draw coal gas from main pipeline, and delivery pipe is directly discharged by delivery pipe for coal gas in sampling process High-altitude prevents gas leak on sample platform, and the valve on fairlead is generally in closed state, needs to check that cloth bag coal gas removes When dirt effect, asbestos print is placed on first through hole upper end, driving device is used to that detection block to be driven to be pressed on lower detection block, It is connected to first through hole with the second through-hole, opens valve, coal gas comes out from main pipeline, successively by fairlead, first through hole, the Two through-holes and delivery pipe are discharged into high-altitude, after a period of time coal gas, close valve, driving device drives upper detection block far under Detection block takes out asbestos print observation dust accumulation situation and judges dust removing effects.
Further, the upper detection block lower end is equipped with annular compression ring, and the annular compression ring is set on the outside of the asbestos print, The lower detection block upper end is equipped with the groove cooperated with the annular compression ring.Cooperation in annular compression ring and groove, increases coal Gas by when leakproofness, keep sampling process safe and reliable.
Further, in order to increase leakproofness of the coal gas by asbestos print when, sealing ring is equipped in the groove.
The beneficial effects of the present invention are: a kind of cloth bag coal gas dust content detection system provided by the invention, using driving device Upper and lower detection block is fitted closely, upper detection block is promoted when sampling, is pasted automatically under driving device effect after being put into coupongs It closes, it is convenient to operate.
Detailed description of the invention
