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

[0019] Such as figure 1 with figure 2 As shown, an atmospheric smoke collection device includes a filter material sampling clip 1 and a support member, and the filter material sampling clip 1 is connected to the upper side of the support member; the filter material sampling clip 1 includes a seat ring 13, a fastening ring 15 and an interface 19, the first filter membrane 11 and the support net 12 are arranged in sequence from top to bottom inside the connecting seat ring 13; Closed contact, a fastening ring 15 is set outside the contact between the interface 19 and the seat ring 13, a second filter screen 16 is set at the edge of the mouth of the interface 19, and a third filter is set in the middle of the mouth of the interface 19. Net 17, the bottom of the mouth of the interface 19 is provided with a fourth layer of filter screen 18.

[0020] The supporting part includes a ventilation pipe 2 and a casing 5. One end of the ventilation pipe 2 is connected to the interface 1...

Embodiment 2

[0023] 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 present invention discloses an atmosphere flue dust collection apparatus, which comprises a filtration material sampling clamper and a supporting component, wherein the filtration material sampling clamper is connected to the upper side of the supporting component, and comprises a connection seat ring, a fastening ring and an interface, the interior of the connection seat ring is sequentially provided with a first filtration membrane and a support net from top to bottom, the interface is hopper-like, the upper end of the interface and the lower end of the connection seat ring form closed contact through a sealing ring, the outer side of the contact position of the interface and the connection seat ring is provided with the fastening ring, the edge position of the hopper opening of the interface is provided with a second filtration screen, the middle portion of the hopper opening of the interface is provided with a third filtration screen, and the bottom portion of the hopper opening of the interface is provided with a four filtration screen. According to the present invention, based on the existing atmosphere collection device, the filtration material sampling clamper is improved, and the multi-layer filtration screen is arranged on the filtration material sampling clamper, such that the particulate matters in the passing air completely fall into the filtration screens so as to improve the data collection accuracy.

Description

technical field [0001] The invention relates to environmental detection, in particular to an atmospheric smoke collection device. 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 concentration of pollutants in the at...
