Abstract
The invention discloses an on-line flue gas monitoring device, which comprises a bypass pipe, wherein the bypass pipe consists of a gas inlet conduit, a gas outlet conduit and a straight pipe, wherein the gas inlet conduit and the gas outlet conduit are connected with the straight pipe in a run-through mode respectively; the front-end sections of the gas inlet conduit and the gas outlet conduit are elliptical; the front-end section of the gas inlet conduit faces a gas stream; the front-end section of the gas outlet conduit backs on to the gas stream; the gas outlet conduit is connected with a flow guide pipe; the gas inlet conduit and the gas outlet conduit are connected with the straight pipe through flanges in a run-through mode; in addition, the two ends of the straight pipe are preferably provided with mounting flanges. By adopting the structure, the on-line flue gas monitoring device can be conveniently mounted and is extremely suitable to be used in large-size flues or at places with high flue dust concentration or gas concentration in the flues.
Description
Technical field
The present invention relates to a kind of flue gas on-Line Monitor Device, especially comprise the flue gas on-Line Monitor Device of shunt valve.
Background technology
In the flue gas on-Line Monitor Device that adopts the correlation direct method of measurement, the general both sides that the emission and the reflection end of flue gas on-Line Monitor Device are installed in flue respectively.If the flue size is little, install more convenient, but when on large-sized flue, installing, often have that difficult installation, platform construction expense are high, the flue dust of high concentration or gas time can't pass to cause and can't measure or surpass the situation of measuring range.
Summary of the invention
The technical matters that the present invention will solve provide a kind of easy for installation, be applicable to the flue gas on-Line Monitor Device of monitoring under large scale flue or the high concentration flue dust situation.
In order to solve the problems of the technologies described above, flue gas on-Line Monitor Device of the present invention comprises shunt valve, and said shunt valve is made up of air inlet skirt, the skirt of giving vent to anger, straight tube, and air inlet skirt, the skirt of giving vent to anger connect with straight tube respectively and be connected.
As improvement of the present invention, the front end section of said air inlet skirt, the skirt of giving vent to anger is ellipse, air inlet skirt front end section object gas flow, the skirt front end section air-flow dorsad of giving vent to anger.
As further improvement of the present invention, be connected with mozzle on the said skirt of giving vent to anger.
In the flue gas on-Line Monitor Device of the present invention, air inlet skirt, the skirt of giving vent to anger are connected preferred flange with perforation between the straight tube.In addition, the straight tube two ends preferably are provided with mounting flange.
Adopt this structure, the flue gas on-Line Monitor Device is easy for installation, very is suitable for dust concentration height or the high occasion use of gas concentration in large scale flue or the flue.Only need a mounting platform, and it is high to have overcome dust concentration, light can't see through and cause situation about can't measure, or gas concentration is high, causes the situation above the range upper limit.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Elaborate below in conjunction with the accompanying drawing specific embodiments of the invention.
Fig. 1 shows concrete structure of the present invention.Flue gas on-Line Monitor Device of the present invention comprises shunt valve, and said shunt valve is made up of air inlet skirt 1, give vent to anger skirt 2 and straight tube 3.Air inlet skirt 1 is welded direct on the flue 7 with the skirt 2 of giving vent to anger; Straight tube 3 keeps parallel with flue 7; Air inlet skirt 1, the skirt 2 of giving vent to anger connect through flange with straight tube 3 and are connected, and the elliptical section of air inlet skirt 1 is over against airflow direction, and the elliptical section of the skirt 2 of giving vent to anger is back to airflow direction.Transmitting terminal 5, the reflection end 6 of flue gas on-Line Monitor Device are installed in respectively on the flange at straight tube 3 two ends.
Because air inlet skirt 1 has pressure reduction with skirt 2 two ends of giving vent to anger, cause flue gas to flow through air inlet skirt 1, straight tube 3, the skirt 2 of giving vent to anger.The oval-shaped end face design in air intake opening and gas outlet has increased the pressure differential at two ends, more helps flue gas flowing in shunt valve.When flue gas flows through straight tube 3; Surveying instrument directly carries out signal sampling to the flue gas in the straight tube 3 of shunt valve; Reached the purpose of real-time monitoring flue gas concentration; Simultaneously, avoided probe directly to contact the corrosion that causes with dirty wet flue gas because probe does not directly insert in the flue, and to the pollution of the eyeglass of popping one's head in.
In order to guarantee flue gas smooth and easy flowing in shunt valve, on the skirt 2 of giving vent to anger, increased mozzle 4, insert pressurized air through the outside and get into, and flow out from the skirt 2 of giving vent to anger from mozzle 4, drive flowing of flue gas.
