Dust Collecting Tank, Dust Deposition Tank

Inner Diameter: 15 ± 0.2 cm

Height: 30±0.4cm

Weight: Not exceeding 1.5 kg

Stainless Steel Dust Suppression Vessels, available in four materials: PVC, Acrylic, Glass, and four types for dust suppression and acid rain component analysis, with advantages such as acid and alkali resistance and good stability.

The dust collection tank is suitable for environmental and hygiene monitoring, sampling atmospheric dustfall and acid rain, as well as for any analysis, testing, and laboratory use as a waste liquid tank and storage for clean liquids.

Basic Content of Dust Deposition Monitoring:

1. Brief Introduction

Dustfall reflects the natural settling amount of particulate matter, expressed as the weight of particles settling on a unit area per month (unit: t/km2·month).

It settles quickly in the air, making it difficult to be inhaled into the respiratory tract. Its natural settling ability primarily depends on its own weight and particle size. It is one of the main indicators reflecting atmospheric dust particle pollution.

Dust reduction is crucial to prevent land desertification.

2. Measure

Subject matter and scope

2.1 Topic Content

This standard specifies the method for measuring dust fall. It employs a wet-sampling technique using an ethylene glycol aqueous solution as the collection liquid, and determines dust fall in ambient air by the gravimetric method.

2.2 Applicability Scope

This standard applies to the determination of settleable particulate matter in ambient air. The detection limit of the method is 0.2 t/km²·30d.

3. Definition

Atmospheric Dust Deposition: Atmospheric dust deposition refers to the particles that naturally settle in dust collectors by gravity under air environmental conditions.

Principle

Particulate matter that can settle in the air is collected in a dust collector tank filled with an ethylene glycol aqueous solution. After evaporation, drying, and weighing, the settled dust amount is calculated.

4. Reagents

All reagents used in this standard, unless otherwise specified, are recognized as analytical grade reagents and distilled water or water of equivalent purity.

Ethylene Glycol (C2H6O2)
