Long-term divided-period atmospheric dry and wet dust-fall acquisition analyzer

Abstract

The invention discloses a long-term divided-period atmospheric dry and wet dust-fall acquisition analyzer. The long-term divided-period atmospheric dry and wet dust-fall acquisition analyzer is characterized in that a dry dust collecting hopper, a wet dust collecting hopper and two expansion instrument bins are arranged on the upper portion of an upright column, a water tank, a dry fallen-dust storage barrel and a wet fallen-dust storage barrel are arranged on the lower portion of the upright column, a cover plate is mounted on the upright column and is horizontally arranged, one end of the cover plate is in running fit with the upright column, the other end of the cover plate covers a port of the dry dust collecting hopper or a port of the wet dust collecting hopper, the water tank is connected with a water outlet of the dry fallen-dust storage barrel by a second control valve, a first water pump is arranged between a first control valve and the second control valve in a connected manner, the first control valve is connected with water injection nozzles on the dry dust collecting hopper, the bottom of the dry dust collecting hopper is connected with a water inlet of the wet fallen-dust storage barrel, and the bottom of the wet dust collecting hopper is connected with a water inlet of the wet fallen-dust storage barrel. The long-term divided-period atmospheric dry and wet dust-fall acquisition analyzer has the advantages that atmospheric dry and wet dust-fall quantities can be acquired and respectively stored by the long-term divided-period atmospheric dry and wet dust-fall acquisition analyzer in divided periods, and conditions of atmospheric dust concentration, dust size distribution, wind speeds and directions and the like can be measured and recorded in the various divided periods.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring equipment manufacturing, in particular to a long-term time-divided atmospheric dry and wet dust collection analyzer. Background technique [0002] At present, dust collection equipment can only collect dry dust or wet dust in a single way, and the instrument must be replaced under different dry and wet conditions. It is impossible to realize the long-term collection of the same instrument according to different situations, and it is also impossible to realize the time-divided collection function. It cannot be used to analyze the time-domain characteristics of dustfall; and the design of the dust storage bucket of the existing instruments is too simple, and it cannot work well in harsh environments or weather conditions. For example, when there is too much precipitation, the existing instruments cannot separate well Dust suppression autonomous drainage. Contents of the invention ...
