According to the whirlwind PM2.5 atmospheric particulate cutter, the sizes of the taper pipe cavity, the cylindrical cavity and the main air hole pipe are set to ensure that particulates with diameters not larger than 2.5 micrometers enter the main air hole pipe, and equipment is detected through the ventilation pipeline, so that an impacting plate and a filter membrane clamp of an ordinary atmospheric particulate cutter are saved.
Description
Technical field
The utility model relates to PM2.5 Atmospheric particulates cutter, relates in particular to cyclone type PM2.5 Atmospheric particulates cutter.
Background technology
PM2.5 is meant that diameter is less than or equal to 2.5 microns particle in the atmosphere, is also referred to as and can goes into the lung particle.Compare with thicker Atmospheric particulates, the PM2.5 particle diameter is little, is rich in a large amount of poisonous, objectionable impuritiess and the residence time in atmosphere is long, fed distance is far away, thereby bigger to the influence of health and atmosphere quality.Country strengthens the monitoring dynamics to PM2.5 in " 12 " planning, PM2.5 becomes must survey one of index; China is in the PM2.5 automated monitor; Main product has β rays method and vibration sedimentation balance method (TEOM) at present, and two kinds of monitoring equipments all must cut PM2.5 gathers screening, and the particle after the screening could get into instrument monitoring; Therefore the accuracy of instrument monitoring data is had higher requirement to the cutting collector; And present cutting collector often precision do not reach requirement, and complex structure, dismounting difficulty.
Summary of the invention
It is higher that the purpose of the utility model provides a kind of precision, simple structure, easy-to-mount PM2.5 cyclone type cutting collector.
The technical scheme of the utility model is cyclone type PM2.5 Atmospheric particulates cutters; It comprises: have hollow channel the column Connection Block, have the taper tube chamber T type Connection Block, have end cap, main stoma tube, the breather line of the end sealing of cylindrical cavity; The openend of end cap is connected the end near narrow bottom surface of taper tube chamber; One end of main stoma tube stretches into the wide bottom end of taper tube chamber; The other end is connected with breather line, and said column Connection Block is fixed on the T type Connection Block, and the hollow channel of column Connection Block communicates with the wide bottom surface of taper tube chamber.
The narrow bottom surface diameter of the taper tube chamber of above-mentioned T type Connection Block is 9mm, and wide bottom surface diameter is 10mm, high 39mm, and the narrow bottom surface of taper tube chamber and side angulation are 17 °.
Cylindrical cavity height in the above-mentioned end cap is 29mm.
Above-mentioned main stoma tube diameter is 9mm, and the length that stretches into the wide bottom end of taper tube chamber is 13mm.
The part that the hollow channel of above-mentioned column Connection Block stretches into the wide bottom surface of taper tube chamber in the projected length of main stoma tube less than 13mm.
The beneficial effect of the utility model is to make minute particle screen selecting through the taper tube chamber go out diameter through the size that taper tube chamber and cylindrical cavity and main stoma tube are set, size to drop in the cylindrical cavity in the end cap greater than 2.5 microns particle; Diameter is not more than 2.5 microns particle and gets into main stoma tube; Reach checkout equipment through breather line, thereby saved the shock plate and the filter membrane clip of general atmosphere particle cutter, provide cost savings; Simplified structure, dismounting is more convenient.
