Problems solved by technology

Among them, the air sampler using the filter material blocking method uses a filter membrane to isolate pollutants in the atmosphere, but in the sampling process of the existing air sampler, particles may bounce back or be blown away from the filter material. Phenomenon, especially in the case of high sampling rate, the particles are easy to pass through the filter and do not settle on the filter. These situations are the reasons for the low collection efficiency

Embodiment 1

[0020] Such as figure 1 and figure 2 As shown, a continuous automatic monitoring device for smoke, dust and smoke includes a filter material sampling clip 1, a connecting piece 23 and a supporting part, the filter material sampling clip 1 is connected to the upper side of the supporting part, and the connecting part 23 is sleeved on the filter The connection between the material sampling clip 1 and the support member is connected through soft materials; the filter material sampling clip 1 includes a seat ring 13, a fastening ring 15 and an interface 19, and the inside of the seat ring 13 is sequentially arranged from top to bottom. The first filter membrane 11 and the support net 12 are set; the interface 19 is bucket-shaped, and the upper end of the interface 19 and the lower end of the seat ring 13 are in closed contact with the sealing ring 15, and the contact between the interface 19 and the seat ring 13 is arranged outside Fastening ring 15, the edge of the mouth of the...

Embodiment 2

[0024] The difference between this embodiment and Embodiment 1 is that the third filter screen 17 is in the shape of an inverted bucket, its apex is fixed on the second filter screen 16, and its edge is fixed on the edge between the second filter screen 16 and the fourth filter screen 18. On the inner wall of the interface 19.

Abstract

The invention discloses a continuous automatic smoke dust and smoke monitoring apparatus. A filter material sampling clamp is connected at the upper side of a supporting part, a connecting piece is sleeved at a junction of the filter material sampling clamp and the supporting part, and a soft material is adopted for the connection; the upper end of a connector contacts the lower end of a joint seat ring in a closing manner by virtue of a sealing ring, the outer side of a contact position between the connector and the joint seat ring is provided with a fastening ring, the middle part of the connector is provided with a third filter net, and the bottom of a block mouth of the connector is provided with a fourth layer filter net; and the connecting piece is a circular-truncated-cone-shaped through pipe, a larger end of an opening of the connecting piece faces the filter material sampling clamp, a smaller end of the opening faces the supporting part, the wall of the inner side of the connecting piece is provided with a circle of connecting piece guide rail, and the outer side of the lower end of the filter material sampling clamp is provided with a circle of connector circular truncated cone matched with the connecting piece guide rail. On the basis of the existing air collector, the filter material sampling clamp is improved, and the filter material clamp is provided with multiple layers of filter nets, so that particulate matters in the air passing through the filter material sampling clamp are ensured to fall on the filter net, and the data collection accuracy can be improved.

Description

technical field [0001] The invention relates to environmental detection, in particular to a continuous automatic monitoring device for smoke, dust and smoke. Background technique [0002] Atmospheric sampling is an important step in atmospheric environment monitoring, and has a great relationship with the reliability of monitoring data. There are two main methods of collecting atmospheric samples: one is to pass a large amount of air through a liquid absorbent or a solid adsorbent to absorb or retain pollutants, and to enrich the pollutants with a lower concentration in the original atmosphere, such as pumping Gas method, membrane filter method. The results measured by such methods are the average concentration of pollutants in the atmosphere during the sampling time. The other is to use containers (glass bottles, plastic bags, rubber bladders, syringes, etc.) to collect air containing pollutants. This type of method is suitable for the following situations: the concentra...
