Description
Technical field
The utility model relates to the volatile device of a kind of detection agricultural chemicals.
Background technology
The volatility of agricultural chemicals, refers to agricultural chemicals from soil surface, the water surface or plant surface by the phenomenon escaped into air of volatilizing.The volatilization of agricultural chemicals can occur in agricultural chemicals production, store and transport, use and use after each stage among, it not only can cause the loss of agricultural chemicals, also can cause the pollution of surrounding environment.Meanwhile, the volatile size of agricultural chemicals, can have influence on the situation that agricultural chemicals is held the property stayed and reallocated in the environment in soil.
For the volatility of evaluating chemical agricultural chemicals in different medium, simultaneously for the registration of agricultural chemicals and use provide environmentology data, under test unit should meet and is applicable to uniform temperature and gas flow rate condition, the volatility of agricultural chemicals in the different mediums such as air, water body and soil.Agricultural chemicals being joined after in different medium, absorb the agricultural chemicals evaporated with absorbing liquid, by measuring absorbing liquid and medium Pesticides content, calculating the volatility of agricultural chemicals.Just under above-mentioned background, invent the agricultural chemicals volatility determinator of utility model.
Utility model content
The purpose of this utility model is to overcome prior art Problems existing, provides a kind of and detects the volatile device of agricultural chemicals, is applicable to measure chemicals and the volatility of agricultural chemicals in the surrounding mediums such as soil, water, air.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
The volatile device of a kind of detection agricultural chemicals, comprise eliminator stack, described eliminator stack is connected with gas meter, described tolerance flowmeter is connected with volatilization room, described volatilization room is connected by air valve with absorption bottle, described absorption bottle is connected with the glass evacuated air distributor of single row of tubes, and the rear end of the glass evacuated air distributor of described single row of tubes connects vacuum pump.
Further, the other end of described eliminator stack is connected with outside air.
Preferably, described eliminator stack seals U-shaped glass tube by 3-5 root and is composed in series, and described U-shaped glass tube is connected by food grade silicone flexible pipe, and is filled with acticarbon and calcium oxide in every root glass tube.
Further, described volatilization room is the resealable container with air intake opening and gas outlet.
Further, described absorption bottle is composed in series by 4 Meng Shi wash bottles, and absorbing agent is housed.
The beneficial effects of the utility model:
Adopt technical solutions of the utility model, simple and easy to do, workable.This device is the static negative pressure absorbing device of enclosure-type, and device structure is simple, connecting line is simple, manufacture and easy to maintenance; And can Simultaneously test many groups sample; Multistage absorption pipe can also be adopted to absorb volatilization agricultural chemicals, guarantee to absorb completely, can meet the demands.
