Abstract
The invention relates to a coal gas detecting and sampling device of a dry dust removal box body capable of improving the detection accuracy and preventing a tester from being poisoned by the coal gas. A centre hole is arranged on the left end face of a sampling pipe cap; a groove which is provided with an opening towards the right side is arranged on the sampling pipe cap; a hole gasket and a detection filter plate are sequentially placed on the inner bottom surface of the groove towards the right; an inner thread is arranged on the inner cylindrical wall of the groove; the cylindrical surface at the left end of the sampling pipe head is provided with an outer thread matched with an inner thread of the groove; an axle hole is arranged at the sampling pipe head; an outer thread is arranged at the right end of the sampling pipe head; the left end of the sampling pipe head is screwed into the groove at the right end of the sampling pipe cap, and the hole gasket and the detection filter plate are tightly pressed. The coal gas detecting and sampling device of the dry dust removal box body is simple in structure, convenient and fast and can prevent the tester from being poisoned by the coal gas.
Description
Technical field
Sampler when the present invention relates to a kind of dried dust-removing box coal gas dust-laden monitoring can improve the accuracy of detection, avoids testing staff's gas poisoning.
Background technology
Dried dust-removing box dust-laden detects the work of all carrying out every day; Adopt glass sheet to detect during detection, before need standing in coal gas floss hole (floss hole is only installed a valve) and opening valve glass sheet is put into valve port, it is on glass that coal gas is blown to; Dust in the coal gas adheres to the dustiness in the coal gas of how much judging of glass; To select wind direction during operation, in case wind direction not to or run into muggy weather and be difficult for coal gas when diffusion, cause the gas poisoning phenomenon easily.Usually in bad weather, have to cancel detection, just can not detect, exceed standard and influence heat generator or the TRT generating set is moved in case there is cloth bag to damage the coal gas dust-laden to casing dust-laden situation in case of continuous many days weather is bad.
Summary of the invention
In order to overcome the shortcoming of prior art, the present invention provides a kind of dried dust-removing box coal gas to detect sampler, and it is simple in structure, and is convenient and swift, can avoid testing staff's gas poisoning.
The present invention solves the technical scheme that its technical matters takes: on the left side of sampling pipe cap center pit is arranged; The groove of the oriented right openings of sampling pipe cap; Place porose pad on the groove inner bottom surface to the right successively and detect filter, on the inner cylindrical wall of groove internal thread is arranged; On the left end face of cylinder of sampling tube head the external thread with described groove screw-internal thread fit is arranged, the sampling tube head has axis hole, and the right-hand member of sampling tube head has external thread; The left end of said sampling tube head screws in the right-hand member groove of described sampling pipe cap, and described hole pad and detection filter are compressed, and is uniformly distributed with axial through hole on the pad of described hole.
The present invention
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Accompanying drawing is a synoptic diagram of the present invention.
Embodiment
Shown in accompanying drawing, on the left side of sampling pipe cap 1 center pit 4 is arranged, the groove 6 of sampling pipe cap 1 oriented right openings is placed porose pad 2 to the right successively and is detected filter 3 on groove 6 inner bottom surfaces, on the inner cylindrical wall of groove 6 internal thread is arranged; External thread with the screw-internal thread fit of said groove 6 is arranged on the left end face of cylinder of sampling tube head 7, and sampling tube head 7 has axis hole 8, and the right-hand member of sampling tube head 7 has external thread 9; The left end of said sampling tube head 7 screws in the right-hand member groove 6 of said sampling pipe cap 1, and described hole pad 2 and detection filter 3 are compressed, and is uniformly distributed with axial through hole 5 on the described hole pad 2.
The left end of said sampling pipe cap 1 passes through fixedly coal-gas recovering cover 10 of screw thread, and the left end of coal-gas recovering cover 10 and flexible pipe 11 are fixing.
During use, the dust-laden that the right-hand member of sampling tube head 7 is installed to gas piping detects mouthful, and flexible pipe 11 is taken back gas piping, opens valve, press official hour and takes a sample.Time is valve-off to the back, takes out the detection filter disc and gets final product.
