Description
Technical field
The utility model relates to a kind of pick-up unit, specifically belongs to the pick-up unit of tar and ash content in coal gas.
Background technology
The by-product gas of steel industry is the most important secondary energy of enterprise.Coal gas plays an important role to the balance of enterprise energy system and adjustment, is also the important source of air-polluting simultaneously.
At present, steel industry is tested mainly through gravimetric method the tar in by-product gas and dust content, namely provides a kind of device testing tar and dust in steel industry coal gas in " GBT 12208-2008 ".This device comprises sample valve, sampler, thermometer, U-tube manometer, wet test meter and gas pipe.Have during the sampling of this device that some is not enough: due to gaspipe network pressure surge, during every sub-sampling, coal gas instantaneous delivery is all not identical, and wet flow indicator record is cumulative amount, can not the instantaneous delivery of measurement gas, make test error larger; And due to sample valve be manually-operated gate, and sample valve aperture can not be controlled accurately, cause accurately measuring under different opening tar and dust content in coal gas; Another also owing to wet flow indicator connecting U-tube manometer meter gaseous pressure, complicated operation, volume is comparatively large, and this device can not realize on-line checkingi and the inquiry of historical data simultaneously, can not accurately reflect tar and dust variation tendency in analysis coal gas.
Through retrieval, patent a kind of " method of the tar content detected in low tar coke-oven gas, application publication number: CN103063596A " be a kind of method detecting tar content in the coke-oven gas of low tar (tar content is at below 10mg/m3), in steel industry coal gas tar content because of user different and different to gas quality demand, this method and apparatus has certain limitation, simultaneously larger by gas pressure influence of fluctuations, can not accurately measure, to contrast under equal gas flow tar and dust content and variation tendency in coal gas, do not utilize post analysis and process, patent " assay method of tar content in a kind of coal gas, application publication number: CN102967565A " be a kind of coal gas is passed into alleviate in surge flask with the flow velocity of 3.5-4 liter/min after, enter in the absorption bottle of in-built absorbing agent, absorb the tar in coal gas by absorbing agent, carry out centrifuging with the rotating speed of 40 ~ 50 revs/min, isolate oil reservoir sample and water layer, get oil reservoir sample in cuvette, at wavelength 320nm place, measure the light absorption value A1 of this oil reservoir sample, thus obtain tar content in coal gas.The method and device bias toward in laboratory operation, in the more difficult complexity of metallurgy industry field conduct, these apparatus and method require higher with when being separated to technical parameters such as the flows of coal gas in sampling simultaneously, and the factor such as on-the-spot gas flow is stressed, temperature impact fluctuation is comparatively large, therefore this kind of apparatus and method can not to meet under the larger condition of gas flow fluctuation user and accurately measure, record and preserve tar and dust content variation tendency under coal gas different flow to tar in coal gas and dust content.
Utility model content
The purpose of this utility model is the deficiency overcoming prior art existence, a kind of content that both can detect tar and dust in coal gas under different accumulative gas flow is provided, also detects under different instantaneous delivery tar and dust content in coal gas for user provides the coal gas of demand and provide the pick-up unit of tar and ash content in the coal gas of foundation.
Realize the technical measures of above-mentioned purpose:
The pick-up unit of tar and ash content in a kind of coal gas, by gas piping, the stopple coupon be connected with gas piping, the manual modulation valve that gas entry end on stopple coupon, stopple coupon connect and sampler, the detection stopple coupon be connected with sampler, the filtrator be connected with detection stopple coupon, be connected to the wet flow indicator on filtrator, computing machine composition, it is: the detection stopple coupon between sampler and filtrator is equipped with ultrasonic flow meter, stopple coupon before manual modulation valve is equipped with operation valve, and operation valve is connected with computing machine by signal wire; Ultrasonic flow meter is connected with computing machine by signal wire; Gas entry end on stopple coupon is Curved, and the installation direction of Curved gas entry end is contrary with the flow direction of coal gas.
Feature of the present utility model: the content that both can detect tar and dust in coal gas under different accumulative gas flow, also by Long-distance Control valve, regulate arbitrarily the instantaneous delivery of coal gas accurately, and detect tar and dust content in coal gas under different instantaneous delivery, for user provides the coal gas of demand and provide tar and ash content in the coal gas of foundation, and can preserve, so that carry out fault analysis.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-gas piping, 2-stopple coupon, 3-Curved gas entry end, 4-manual modulation valve, 5-sampler, 6-detect stopple coupon, 7-wet flow indicator, 8-computing machine, 9-ultrasonic flow meter, 10-operation valve, 11-signal wire.
Embodiment
Be described further below in conjunction with accompanying drawing:
The pick-up unit of tar and ash content in a kind of coal gas, by gas piping 1, the stopple coupon 2 be connected with gas piping 1, the manual modulation valve 4 that gas entry end 3 on stopple coupon 2, stopple coupon 2 connect and sampler 5, the detection stopple coupon 6 be connected with sampler 5, the wet flow indicator 7 be connected with detection stopple coupon 6, computing machine 8 form, its detection stopple coupon 6 between sampler 5 and wet flow indicator 7 installs ultrasonic flow meter 9, stopple coupon 2 before manual modulation valve 4 installs operation valve 110, and operation valve 10 is connected with computing machine 8 by signal wire 11; Ultrasonic flow meter 9 is connected with computing machine 8 by signal wire 11; Gas entry end 3 on stopple coupon 2 is Curved, and the installation direction of Curved gas entry end 3 is contrary with the flow direction of coal gas.
During use, by ultrasonic flow meter 9 on-line checkingi sampling coal gas instantaneous delivery, and flow signal is transferred to computing machine 8, by the aperture of computing machine 8 regulable control operation valve 10, make tar and dust content in the equal sample flow Coal Under gas of measurement, reduce test error.Simultaneous computer 8 can record preserves gas flow change curve between sampling date, is convenient to later stage test data analyzer and checks historical data.
This embodiment is only the best and exemplifies, the restricted enforcement not to technical solutions of the utility model.
