An object of the utility model is to overcome not enough among the prior art, provide an air sampler for exhaust-gas detection, this kind of air sampler for exhaust-gas detection can make the temperature environment of absorption liquid invariable relatively to can improve the speed that solution absorbed waste gas.
In order to solve the prior art problem, the utility model discloses an air sampler for waste gas detection, which comprises a sampling pipe, wherein the sampling pipe is connected with an air suction device, the air suction device is connected with a buffer bottle through a pipeline, the top of the buffer bottle is provided with an air outlet pipe, switch valves are arranged at the pipeline part entering the buffer bottle and the air outlet pipe of the buffer bottle, the air outlet pipe at the top of the buffer bottle is connected with the sampling bottle, absorption liquid is filled in the sampling bottle, the air outlet pipe is spirally arranged in the sampling bottle, a plurality of air outlet holes are arranged on the air outlet pipe body, and the air outlet pipe extends out of the top of the sampling bottle; be provided with temperature sensor on the outer wall of sampling bottle, the outside of sampling bottle is provided with an intermediate layer, is provided with the heating chamber in the intermediate layer outside, the heating intracavity is provided with the heater strip.
Preferably, the top of the buffer bottle is also provided with a vacuum tube.
Preferably, the outside of the air outlet pipe in the sampling bottle is coated with a polytetrafluoroethylene coating.
The utility model discloses a use method does: when the vacuum buffer bottle is used, the switch valve at the inlet and the outlet of the buffer bottle is closed, the interior of the buffer bottle is vacuumized from the vacuumizing pipe by using vacuumizing equipment, and then the vacuumizing pipe is sealed; place the position department that needs the sampling again with the sampling pipe, open the ooff valve of buffer flask exit, open the device that will induced draft and make the waste gas of absorption enter into the buffer flask in, during gas in the buffer flask slowly enters into the tuber pipe under the promotion of the device that induced drafts, then constantly ooze from the air outlet department, dissolve in the liquid of drawing, after waiting to dissolve a period, will draw the liquid and pour out and detect.
The utility model has the advantages that: 1. the suction effect is better. Set up the buffer bottle, waste gas is the buffering in entering into the buffer bottle earlier, then slowly enters into the play tuber pipe in the sample bottle, and waste gas is slow oozes, has avoided directly absorbing other problems such as splash that appear, and the absorption effect is better. 2. The air outlet pipe in the sampling bottle is designed in a spiral shape, so that the walking path of waste gas in the sampling bottle is greatly prolonged, the problems of only dissolving on the surface and the like are avoided, and the dissolving efficiency is greatly improved; 3. the heating chamber has been set up in the outside of sampling bottle, and the heating intracavity sets up the heater strip, and the heater strip can external circuit, provides the heat for the sampling bottle, still is provided with the intermediate layer between heating chamber and sampling bottle, so can guarantee that the temperature in the sampling bottle is more balanced, heater strip department high temperature can not appear, and the lower condition of other position department temperatures. The outside at the sampling bottle is provided with temperature sensor, can show the temperature interval, reminds testing personnel to operate when the high temperature or low excessively.
