Description
Technical field
The utility model relates to a kind of low-concentration smoke sampling rifle.
Background technology
Along with the fast development of Chinese national economy, air environmental pollution problem is increasingly serious, and the diastrous weather such as haze, acid rain of big and medium-sized cities takes place frequently, and has had a strong impact on physical and mental health and the normal life of people.Coal-burning power plant, as one of the important pollution source of Air Pollutant Emission, always is the focus that people pay close attention to." fossil-fuel power plant atmospheric pollutant emission standard " (GB 13223-2011) requires that soot emissions limit value in key area is 20mg/m
3.Near coal-burning power plant's atmosphere pollution " minimum discharge " becomes much-talked-about topic one year over, and namely coal unit will reach or lower than gas turbine group standard limited value, flue dust, SO
2, NOx emission limit value is respectively 5mg/m
3, 35mg/m
3, 50mg/m
3(flue dust, SO that " coal electricity energy-saving and emission-reduction upgrading and transformation action plan (2014 ~ the year two thousand twenty) " provides
2, NOx emission limit value is respectively 10mg/m
3, 35mg/m
3, 50mg/m
3).
The atmospheric pollution situation that China is increasingly serious and the country becoming tight and local policy, standard facilitates the fast development of China's dedusting technology, but bring huge challenge also to the existing Technology of Smoke-dust of China simultaneously, but state's inner flue gaging hole is 80mm at present, much external sampling with high precision equipment cannot stretch into flue because diameter is excessive, former gaging hole outshot is had to slice off during test, arrange and cannot test at all, Some Domestic scholar it is also proposed and all changes domestic all flue gaging holes into the 125mm even suggestion of larger diameter, but it is huge all to change gaging hole cost.Therefore, explore and develop a kind of scientific and reasonable tobacco damping-off Apparatus and method for being applicable to China's low concentration smoke and dust environment and gaging hole size, extremely urgent.

Preferably, described sampling head outer wall is provided with electric heater; Increase temperature and obtain sample more accurately.
Preferably, described rotation and stationary installation comprise two pieces of web joints laying respectively at the left and right sides, rifle body front end, the card connected by two pieces of web joints, the horizontal fixed plate that is used for fixed sample head, described web joint is rotationally connected by the front end of bearing pin and rifle body, described rifle body front end is provided with to contact with card when sampling head forwards to parallel with rifle body axis carries out spacing Compact Mounts to sampling head, when sampling head forward to its axis at a right angle with rifle body axis time horizontal fixed plate contact with rifle body top end face; Can control the anglec of rotation of sampling head, prevent from excessively rotating causing returning to normal sampling location.
Preferably, the end of described sampling head is less than 40mm to the distance of bearing pin axis; So just can put in easily in the pipeline of existing diameter 80mm.
Preferably, the lower end of described pull bar is provided with pull bar stationary installation, described pull bar stationary installation comprises the upper stator and lower stator of embracing rifle body, leave expansion joint between one end of fixed and one end of lower stator and be bolted, the other end of fixed is all fixedly connected with the lower end of pull bar with the other end of lower stator; Be convenient to the fixing of pull bar, thus the position of sampling head can be fixed, conveniently measure.
Compared with prior art, the utility model has the advantages that: sampling head rotates and is arranged on rifle body front end and can controls its rotational angle by pull bar, can very easily by the gaging hole of 80mm internal diameter, make state's inner flue gaging hole without the need to whole transformation, save the objective investment for trnasforming urban land of a stroke count order, and expand the scope of application of smoke dust sampling gun.

Embodiment
Consult the embodiment that Fig. 1, Fig. 5 are a kind of low-concentration smoke sampling rifle of the utility model, a kind of low-concentration smoke sampling rifle, comprise rifle body 2, by the pressure tester 5 rotated and stationary installation 3 is connected to the sampling head 1 of rifle body 2 front end, the pull bar 4 of control sampling head 1 rotation and is fixed on rifle body 2, described sampling head 1 is connected with the rifle head tube 19 of rifle body 2 by connecting hose.
As shown in Figure 2, described sampling head 1 comprises filter cylinder 9, be fixed on the sampling nozzle 8 of filter cylinder 9 front end and be connected to the connecting pipe 10 of filter cylinder 9 rear end, the front end of described flexible pipe is connected with connecting pipe 10, and upper end and the connecting pipe 10 of described pull bar 4 are rotationally connected, and described sampling head 1 outer wall is provided with electric heater.
