A method for rapidly forming extinction-type bioaerosol at a predetermined height

A bioaerosol and predetermined height technology, which is applied in aerosol preparation, chemical instruments and methods, vehicle position/route/height control, etc., can solve the problem of not being able to form an extinction-type bioaerosol with a certain area, thickness and concentration. No problems such as extinction, low cost, uniform spraying, and improved spraying efficiency

Embodiment Construction

[0042]Detailed description will be described in detail below with reference to the accompanying drawings.

[0043]This example gives a method of rapidly forming a maturity biomariol sol in a predetermined height, the method comprising the steps of:

[0044]Step 1, according to the horizontal direction of the extinctional biological aerosol to form a sheet2, Drone flight speed V2And extinctional biological particles falling speed V1And extinction type biomass sol transfority V0, Determine the time t required to form a film-based biological aerosol0.

[0045]The shorter the diffusion time, the better, due to the increase of time, the smoke concentration (ie, the extinctional biological gas sol) is smaller and smaller, the extinction performance is weakened, each spout is also separated from a certain distance, and the extinctional biological gas formed when sprayed out. The sol concentration is uneven, and the speed of the drone flight speed, the diffusion time is not less likely to be small. ...

Abstract

The invention discloses a method for quickly forming an extinction type bioaerosol at a predetermined height, comprising: determining the time required to form a sheet of extinction type bioaerosol; calculating the flight height to be reached by the UAV; calculating the flight height of the UAV The spray flow rate of the spraying device; put the extinction-type biological particles into the extinction-type biological particle box of the drone spraying device and cover the upper cover of the extinction-type biological particle box; control the drone to fly to the desired flight height and adjust the unmanned The posture of the machine makes the spray pipe parallel to the plane where the extinction bioaerosol is located and is suspended above the edge of one side of the sheet of extinction bioaerosol; the blower is turned on by remote control and the UAV is controlled to fly at the desired formation speed. Fly back and forth between the left and right sides of the extinction type bioaerosol of the sheet and spray with the spray flow at the same time. The invention can quickly form the extinction type biological aerosol with a certain area, thickness and concentration at a predetermined height to achieve the purpose of extinction.

Description

Technical field[0001]The present invention belongs to the technical field of biomolic sol production, and is, in particular, to a method of rapidly forming a matte biomeper solution at a predetermined height.Background technique[0002]A uniformly distributed aerosol is formed in the atmosphere, which has an extinction to attenuate electromagnetic waves of a particular wavelength propagated in an aerosol.[0003]The aerosol in the atmosphere is mainly from the emissions of nature and human activities. The natural source of aerosol includes ground sources, marine sources, atmospheric itself, and external spatial injection. Artificial aerosols are various particles discharged by human activity, including native primary particles and contaminated gas chemical or photochemically produced secondary aerosols, mainly from combustion, industrial and agricultural production activities of fossil fuels. Atmospheric aerosols in many atmospheres, the radiation balance, the electronics of electronics...
