Background technology
At present, flue gas desulfurization is generally installed in thermal power generation corporations, and the direct perforate of desulphurization system test measuring point burn into easily occurs and stops up, and measuring point is fragile, desulphurization system operation under positive pressure, and high temperature, poisonous sulfur-containing smoke gas are spouting, and the personnel that easily cause burn and are poisoning.In addition, energy-saving and emission-reduction, total amount of pollutant control, environmental protection facility postitallation evaluation, all need often environmental protection facility to be monitored, evaluated, and desulphurization system is not installed the point equipment of adaptation, directly opens the gaging hole personnel that also should cause and injures.In order to overcome above-mentioned shortcoming, this area researcher has carried out a large amount of research, for example application on April 1st, 2013 CN201320155505.6, although can prevent that the burn into of point equipment from stopping up, isolated flue gas injection, the personnel that avoid causing injure, but there is deviation for detection architecture, because the structure of tubular easily causes eddy current or the delay of flue gas, cause the sulfur content of the flue gas in an interior flue gas and desulphurization system inconsistent, cause measurement result incorrect.
Utility model content
The purpose of this utility model is to provide a kind of anticorrosion, anti-blocking, flue gas of the flue gas for high temperature, poisonous, operation under positive pressure, the anti-blocking blowout prevention smoke collecting device of anti-eddy current.The burn into that can prevent point equipment stops up, isolated flue gas injection, and the personnel that avoid causing injure and avoid causing local flue gas to be detained, and possess sampling convenient, measure reliable advantage.
For achieving the above object, technical solution adopted in the utility model is:
A kind of anti-blocking blowout prevention smoke collecting device, it comprises unpacking cylindrical shell and the sampler barrel that is arranged at described unpacking cylinder lateral wall and communicates with described unpacking cylindrical shell, described unpacking cylindrical shell lower end is provided with opening, upper end is provided with top cover, on described top cover, be provided with threaded hole, described unpacking inner barrel is equipped with piston, described piston is made up of anticorrosion plug and the polytetrafluoroethylene floor that is wrapped in described anti-blocking plug bottom and outer wall, described piston upper end is provided with screw rod, on described screw rod, be provided with the screw thread matching with described threaded hole, described unpacking inner barrel top is equipped with sealing gasket, in the middle of described sealing gasket, be provided with screw rod jack, described sampler barrel top is provided with gland bonnet.
As further improvement of the utility model, comprise the rifle plug of combining use with described sampler barrel, described rifle plug is provided with thieff hatch.
As further improvement of the utility model, wherein gland bonnet is that buckle-type is connected with described sampler barrel.
The beneficial effect that the utility model is obtained is:
Because the utility model adopts the thinking design of piston seal, use the piston cylindrical shell lower seal of break seal, the inner barrel of can avoiding breaking seal produces cavity and causes flue gas delay, causes local amount of sulfur contenting in smoke inhomogeneous.And because piston seal has avoided unpacking inner barrel flue gas excessive, be provided with sealing gasket on unpacking inner barrel top, can avoid the dust entering from threaded hole to enter sampler barrel, ensure device security, anti-blocking, easy, reliable, ensure the personal safety in operation process, simple, convenient, safety.And ensure the accuracy of sampling.
