Abstract

The utility model relates to a fog sampler used for collecting natural fog or artificial fog, which is used for the research for the chemical behaviors of fog in the fields of environment, electric power, material science, etc. A sampling tube of the sampler is a straight tube, a sloping sampling head is arranged in the inlet end of the sampling tube, and the outlet end of the sampling tube is provided with an exhaust blower. The sampling head is formed by that four to six layers of wire meshes, the line diameter of which is 0.30 millimeters to 0.52 millimeters are inserted into a frame in parallel, and fog liquid after coagulated on the wire meshes is gathered in a liquid receiving disc and is collected. The fog sampler has simple structure, high efficiency for collecting fog, regular appearance and portability, and meets the demands of fog collection in the field.

Description

Fog sampler

The utility model is the sampling thief about aerial fog or artificial mist, is used for the research that fields such as environment, electric power or materialogy to the atomizing scholarship and moral conduct are.

At present, in numerous fog sampling thiefs, comparatively typical with rotary type sampling tube and v-shaped tube exhausting formula sampling thief, wherein rotary type sampling tube is to utilize two to bump and principle that its coalescence is caught is made at the sampling cup of air high speed rotation and droplet, this device for mechanical complex structure, and low to the collecting efficiency of small particle diameter droplet; V-type exhausting formula sampling thief is the V-arrangement pipe that adopts 100 millimeters calibers, by air exhauster coalescence in the fog inlet tube and on mouth of pipe silk screen is become droplet, flows down along pipe, collects in the elbow of v-shaped tube.It is limited to adopt the mist amount in this device unit interval, and bend pipe carries and install all inconveniently, is unsuitable for the needs that mist is adopted in the field.

The purpose of this utility model provides a kind of sampling efficiency height, and is simple in structure, fog sampling thief easy to carry.

The utility model fog sampling thief is by sampling pipe, air exhauster and sampling head are formed, sampling pipe is a straight tube, 4～6 layers of silk screen assign in the framework side by side, form sampling head, tilting in the entrance point of sampling pipe by fixed block, web lines directly is the 0.30-0.52 millimeter, the spacing of each layer silk screen is the 4-6 millimeter, and the sampling head lower end is provided with and connects the sample dish.Contain fog stream and taken out the introducing sampling pipe by air exhauster, droplet becomes the suitable stream off the net of big droplet to gather in liquid dish with silk screen bump coalescence, can regularly take out and connect sample dish collection spray film, collects with sample bottle.

The utility model fog sampling thief captures the efficient height of fog, compare with existing sampling thief, unit interval adopts the mist amount and improves greatly, thereby can realize once falling the sampling at times of mist process, so that to the fog chemical behavior in the day part and pollute the physics settling process and study.This fog sampling thief compact conformation, the profile rule, in light weight, volume is little, is easy to carry, and adapts to the needs of field sampling.

Below in conjunction with description of drawings embodiment of the present utility model.

Fig. 1 is the front section view of the utility model fog sampling thief.

Fig. 2 is the A-A sectional view of Fig. 1.

Fig. 3 is the sampling head front view (FV).

What Fig. 1-Fig. 3 showed is an example structure of the present utility model, in the present embodiment, sampling pipe is square straight tube, the endpiece of sampling pipe 2 is provided with air exhauster 1, tilting sampling head is arranged in the pipe of entrance point, its upper end is by fixed block 3 location of sampling pipe inwall, it is made up of framework 4-1 and 4～6 layers of silk screen 4-2 that insert in the framework arranged side by side, its upper end is fixed on the fixed block 3 of pipe 2 inwalls, the lower end places in the liquid dish 5, liquid dish has a catheter 6 to stretch out outside the sampling pipe, can connect with sample bottle and collect.Present embodiment is set up perforated baffle 7 between air exhauster and sampling head, can make the air-flow that enters sampling thief more steady, reduces eddy current.
