Abstract
A sampler for detecting oil content and dust content in coke oven gas is characterized by a shape small in the two ends and big in the middle part, wherein the two ends have such a size and a shape that both ends can be connected to a gas hose and a flow meter; and two layers of quartz sand filter screens are arranged at the middle part. The sampler for detecting oil content and dust content in coke oven gas is capable of normally taking a sample within a gas positive-pressure region, and also capable of realizing normal sampling in any place within a pipeline and further capable of detecting particles and liquid drops smaller than 0.6 microns; and the sampler is simple to operate and accurate in detection result.
Description
Technical field
The utility model belongs to the chemical detecting instrument, is the ST that a kind of metallurgical coking industry is used for detecting coke-oven gas oil-containing dustiness.
Background technology
At present; Metallurgical coking industry detects the method that contains tar and dustiness in the coke-oven gas; The general solvent absorption that adopts promptly adopts absorbing agent that the tar in the coke-oven gas is absorbed, and through gravimetric method or other physicochemical analysis methods the tar in the coke-oven gas is detected again.Most of metallurgical coke-oven plant adopts the glass ST, but all only limits to be applied in the coke-oven gas negative pressuren zone.And can not normally take a sample at zone of positive pressure, or very big artificial error of sampling existence and Systematic Errors, can not normally detect coke-oven gas oil-containing and dustiness.
The utility model content
The utility model aims to provide a kind of ST that is used for detecting coke-oven gas oil-containing dustiness.This ST goes for all through the sampling of the coke-oven gas behind the process for purifying.
The technical scheme of utility model is: be used for detecting the ST of coke-oven gas oil-containing dustiness, two is little broad in the middle, and two size shape can connect gas pipe hose and flowmeter, and there is two-layer quartz sand filtration net the centre.
During use, one connects gas pipe hose, and one connects flowmeter.Make the quartz sand filtration net of quantitative coke-oven gas through known quantity, screen pack is weighed after super-dry, obtains tar and dust content in the coke-oven gas by the weight of its increase.
The advantage of utility model: the utility model can normally be taken a sample at the coal gas zone of positive pressure, at pipeline Anywhere, all can realize normal sampling, and can detect particle and the drop less than 0.6 μ m that simple to operate, testing result is accurate.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the screen pack enlarged drawing;
Among the figure: 1-gas entry pipe, 2-glass ectosome, 3-micropore quartz sand filtration net, 4-gas outlet tube.
Embodiment
Further specify the content of the utility model below in conjunction with the embodiment of accompanying drawing.
As shown in the figure: be used for detecting the ST of coke-oven gas oil-containing dustiness, two is little broad in the middle, and one the other end is the gas outlet tube 2 that connects flowmeter in order to connect the gas entry pipe 1 of gas pipe hose, and there is two-layer quartz sand filtration net 3 centre.Because oils drop and other particle grades in the coke-oven gas account for the overwhelming majority at 0.6 μ m,,, just can detect oils drop and the content of other particles in the coke-oven gas with the gravimetric method detection so utilize the quartz sand filtration net filtration of 0.6 μ m.Present embodiment employing internal diameter is the circular glass pipe interior (wall thickness is 1.5mm) of 15mm for this reason; The 40mm that is spaced a distance is provided with the micropore quartz sand filtration net of two-layer certain thickness 2mm; Gas gets into from ST one end; Through behind the two-layer screen pack, various oils drops are online at quartz sand filtration with the particle filtration, thereby just can detect the weight of oils drop and dust in the coke-oven gas.Connect with gas pipe hose and flowmeter for the ease of ST, gas entry pipe and gas exit internal diameter are designed to 8mm.
