Description

Dissolved petroleum sewage sampler

Technical Field

The utility model belongs to the technical field of the sewage sampling, concretely relates to dissolve petroleum class sewage sampler.

Background

The exploitation, transportation, application and the like of petroleum inevitably pollute adjacent water areas, so the detection of petroleum sewage belongs to a necessary measurement project in the monitoring project of surface water. In petroleum-based sewage, petroleum mainly exists in three ways: floating oils, emulsified oils and dissolved oils. In the monitoring of petroleum sewage, the collection of water samples is an important part of the monitoring.

To the sample of dissolving oil sewage, need place the surface of water below in appointed waters with the sampling bottle, before the sample, according to the length of the rope between floater and bottle lid that has set well earlier, put sampler in aquatic again, when waiting to the suitable position, the rope is tightened the back bottle lid and is pulled up, the rivers of this degree of depth flow into to the sampling bottle in, the operator pulls up the sampling bottle, the rope is lax this moment, the spring is with the bottle lid butt in the port of sampling bottle, it is sealed with the sampling bottle.

Although above-mentioned operation process is simple, in above-mentioned sample bottle, the bottle lid bottom just can improve sealed effect owing to set up joint strip for sewage in the sample bottle can be direct and the joint strip contact, and because petroleum class sewage can produce chemical reaction with the adhesive tape, thereby the sewage that leads to the sample receives secondary pollution.

SUMMERY OF THE UTILITY MODEL

To exist not enough among the prior art, the utility model provides a dissolve petroleum type sewage sampler to petroleum type sewage can produce chemical reaction with the adhesive tape in solving current sample bottle, thereby leads to the sewage of sample to receive secondary pollution's problem.

In order to achieve the above purpose, the utility model adopts the following technical scheme:
