Description
技术领域technical field
本发明属于建筑环境检测领域，具体涉及一种室内空气采样分析装置。The invention belongs to the field of building environment detection, in particular to an indoor air sampling and analysis device.
背景技术Background technique
目前广泛应用于室内空气样品收集的装置是大型气泡吸收管，见说明书附图1，由气泡管1、进气管2、排气管3组成，进气管2通入气泡管1的底部，排气管3与气泡管1的上部连通，气泡管内装有专用有毒有害气体吸收液，现有检测方式是先用气泡吸收管收集有毒有害气体，收集完成后密闭运输到实验室，再将吸收液转入比色管中进行比色分析，吸收液转移过程中可能吸收外界空气中的气体，造成检测误差，同时步骤繁琐，增加仪器清洗等工作量和清洗液的处理量。At present, the device widely used in the collection of indoor air samples is a large-scale bubble absorption tube, see Figure 1 in the description, which is composed of a
发明内容SUMMARY OF THE INVENTION
本发明是为了解决现有室内空气采样分析中操作步骤繁琐的技术问题而提供一种室内空气采样分析管。The invention provides an indoor air sampling and analysis tube in order to solve the technical problem of complicated operation steps in the existing indoor air sampling and analysis.
本发明的室内空气采样分析管包括比色管、进排气塞、密闭塞，比色管、进排气塞、密闭塞均为玻璃材质，所述比色管的管口是磨砂锥形口，比色管上标有容积刻度，所述进排气塞包括瓶塞、进气管、排气管，瓶塞通过磨砂锥形面插接在比色管的管口，瓶塞内设置有连通比色管和排气管的空腔，进气管穿过瓶塞后伸入比色管的底部，所述密闭塞用于气体采样完成后将比色管密闭。The indoor air sampling and analysis tube of the present invention includes a colorimetric tube, an inlet and exhaust plug, and an airtight plug. The colorimetric tube, the air inlet and exhaust plug, and the airtight plug are all made of glass, and the orifice of the colorimetric tube is a frosted conical port. , the colorimetric tube is marked with a volume scale, the intake and exhaust plugs include a bottle stopper, an air intake pipe, and an exhaust pipe. The bottle plug is inserted into the mouth of the colorimetric tube through the frosted conical surface, and the bottle plug is provided with a communication The cavity of the colorimetric tube and the exhaust pipe, the air inlet pipe extends into the bottom of the colorimetric tube after passing through the bottle stopper, and the airtight plug is used to seal the colorimetric tube after the gas sampling is completed.
进一步的，所述进气管的下部包裹有玻璃环，玻璃环的体积可以排挤吸收液，使吸收液的液面升高，增加气体与液体的接触时间，相同液面高度情况下可减少吸收液的用量，节约进气时间，更进一步的，所述比色管的容积刻度有两处，一处是没有插装进气管的刻度，另一处是插装进气管后的刻度。Further, the lower part of the air inlet pipe is wrapped with a glass ring, the volume of the glass ring can displace the absorption liquid, make the liquid level of the absorption liquid rise, increase the contact time between the gas and the liquid, and reduce the absorption liquid under the same liquid level. In addition, the volume scale of the colorimetric tube has two points, one is the scale without inserting the intake pipe, and the other is the scale after inserting the intake pipe.
使用时，打开密闭塞，往比色管中加入适量的吸收液，装上进排气塞，进气管接入取样设备的流量泵，启动流量泵，将室内空气进入本发明的装置，有毒有害成风通过比色管中的吸收液吸收，实现气体采样，采样完成后取出进排气塞，装上密闭塞，送入实验室比色分析，完成室内空气的采样分析。When in use, open the airtight plug, add an appropriate amount of absorbing liquid into the colorimetric tube, install the intake and exhaust plug, connect the intake pipe to the flow pump of the sampling equipment, start the flow pump, and enter the indoor air into the device of the present invention, which is toxic and harmful. Through the absorption of the absorption liquid in the colorimetric tube, gas sampling is realized. After the sampling is completed, the intake and exhaust plugs are taken out, installed with airtight plugs, and sent to the laboratory for colorimetric analysis to complete the indoor air sampling and analysis.

The colorimetric tube, the air inlet and exhaust plugs, and the airtight plug are all made of glass. The volume scale is marked on the colorimetric tube. The inlet and exhaust plugs include a bottle plug, an air inlet pipe, and an exhaust pipe. The bottle plug is inserted into the mouth of the colorimetric tube through the frosted conical surface. The bottle plug is provided with a communication ratio. The cavity of the color tube and the exhaust tube, the intake tube extends into the bottom of the colorimetric tube after passing through the bottle stopper, and the sealing plug is used to seal the colorimetric tube after the gas sampling is completed, so as to realize the sampling in the colorimetric tube And colorimetric analysis, compared with the existing operation, the steps of transferring the sample from the bubble absorption tube to the colorimetric tube are reduced, which is beneficial to improve the detection accuracy and improve the detection efficiency.
