Abstract

The utility model discloses a dust content detection device for blast furnace gas, which includes a detector, wherein the detector includes a casing, as well as a support net and a filter paper both arranged in the casing; an inlet is arranged at one end of the casing; the casing is connected with a blast furnace gas source through a collection hose; and an outlet is arranged at the other end of the casing. Through filtering dust in the blast furnace gas and by fire drying and weighing, the detection result can be obtained, the simple and convenient effects can be achieved, and the detection safety can be ensured by arranging a reducing valve.

Description

A kind of blast furnace gas dustiness proofing unit
Technical field
The utility model relates to blast furnace gas quality inspection equipment, more particularly, relates to a kind of blast furnace gas dustiness proofing unit.
Background technology
Blast furnace gas is the significant by-products that blast furnace ironmaking is produced, and can be used as the fuel of the Cheap highly effective of other flow processs in the Steel Complex.Blast furnace gas gets into gravitational precipitator from the furnace roof upcast through downtake, and about 40% macrobead dust is stayed in the gravitational precipitator and discharged through ash ejector in the raw gas.The initially treated raw gas of process gets in the follow-up gas purification process equipment to be handled, and the purified gas dustiness that requires to handle is less than 5mg/NM 3
Tracking for through gas quality after the purifying treatment detects, and be at present to adopt online dust concentration meter, but because various dust concentration meters all can't place the work condition environment of standard to demarcate, the data that therefore record only can be as the reference of relative undulating quantity.Mode is to adopt the sampling weighting method to measure the most accurately.In addition; Modern blast furnace all is provided with the top pressure power generation system behind gas purification process; The remaining pressure power generation turbine rotor if the coal gas that a large amount of dust concentrations exceed standard is flowed through; Can cause the rotor severe impairment, therefore must guarantee gas quality getting into the accurate assurance of remaining pressure power generation turbine dust content of gas before and in time taking the adjustment measure.For the subsequent user of blast furnace gas, dustiness exceeds standard and will cause product quality defect in the coal gas.
In sum, accurately measuring dustiness for blast furnace gas is necessary.Because the coal gas dry-method dust collecting process has singularity, must on the high pressure-temperature gas line, measure dust content of gas, exists bigger safety-problems.
The utility model content
To the above-mentioned shortcoming that exists in the prior art, the purpose of the utility model provides a kind of blast furnace gas dustiness proofing unit, can be implemented under the coal gas dry-method dedusting condition, measures the blast furnace gas dustiness in HTHP coal gas pipeline section safety.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
This blast furnace gas dustiness proofing unit comprises detector, and detector comprises housing, is located at intravital supporting network of shell and filter paper, and housing one end is provided with inlet, and links to each other with the blast furnace gas source through gathering flexible pipe, and the housing the other end is provided with outlet.
Described housing symmetricly is half bucket-shaped shell facies and connects and composes by two, also is provided with sealing-ring between half shell.
Described two halves shell outer rim all is flange-like, and is connected through bolt.
Described proofing unit also comprises reducing valve, the wet test meter that is connected with the housing outlet successively, and the wet test meter the other end is connected with discharging hose.
In technique scheme; The blast furnace gas dustiness proofing unit of the utility model comprises detector, and detector comprises housing, is located at intravital supporting network of shell and filter paper, and housing one end is provided with inlet; And link to each other with the blast furnace gas source through gathering flexible pipe, the housing the other end is provided with outlet.Through the dust in the filter paper filtering blast furnace gas, and through oven dry, weigh can obtain detected result, and is simple and convenient, and guarantees to detect safety through reducing valve is set.
Description of drawings
Fig. 1 is the synoptic diagram as a result of the proofing unit of the utility model;
Fig. 2 is the exploded view of the detector of the utility model.
Embodiment
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and embodiment.
See also Fig. 1~shown in Figure 2; The blast furnace gas dustiness proofing unit of the utility model comprises detector 1; This detector 1 comprises housing 2, is located at supporting network 3 and filter paper 4 in the housing 2; Housing 2 one ends are provided with inlet 5, and link to each other with the blast furnace gas source through gathering flexible pipe 6, and housing 2 the other ends are provided with outlet 7.Wherein, described housing 2 symmetricly is half bucket-shaped shell facies and connects and composes by two, and described two halves shell outer rim all is flange-like, and is connected through bolt 8, and also is provided with O-ring seals 9 between half shell, plays sealing function.Described proofing unit also comprises reducing valve 10, the wet test meter 11 that is connected with housing 2 outlets 7 successively, and wet test meter 11 the other ends are connected with discharging hose 12.
The detection principle of the proofing unit of the utility model is following:
At first, filter paper 4 according to standard oven dry marked and weigh subsequent usely, is installed in filter paper 4 in the housing 2 of detector 1 then; To gather flexible pipe 6 again and link to each other with coal gas conveying end on the gas line, the conveying end valve that turns on the gas-fire is emitted blast furnace gas; When the coal gas total amount that the record wet flow indicator flows through reaches set(ting)value (for example 500 liters), close the conveying end valve, take out filter paper 4; Dry again and weigh, with filter paper 4 net weight comparison before, the accurate data of dustiness in the unit's of drawing coal gas.
In sum, adopt the proofing unit of the utility model to have following advantage:
When 1, measuring, reducing valve 10 can make the gas pressure of detector 1 keep high pressure, and there is not very big pressure reduction in filter paper 4 front and back, guarantees that filter paper 4 can absorb the dust in the coal gas fully and be unlikely to damaged.
2, the pressure behind the reducing valve 10 is lower, has guaranteed the safe operation of wet flow indicator.
3, discharging hose 12 can be placed on range finding personnel following air port far away, can not cause mensuration personnel carbon monoxide poisoning.
4, the weight of weighing filter paper 4 can adopt the rigorous analysis balance, and gas flow also has record, therefore can comparatively accurately reflect actual dustiness in the blast furnace gas objectively.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
