Description

Organic Pollution water sample pump line mouth sampling thief
Technical field
The utility model relates to a kind of harvester of the water sample that contains volatilization, half volatile material, specifically a kind of Organic Pollution water sample pump line mouth sampling thief.
Background technology
Suffer the water sample of Organic Pollution, due to its singularity that contains volatilization, half volatile material, the collection of its sample is different to the acquisition method of other water sample.
At present, the acquisition method of conventional Organic Pollution water sample is to extract the solid fire hose of pump line mouth place larynx banding of pollution water sample then the mode collected specimens of shunting by four-way.Sample unit used mainly comprises sample collection four-way, four-way shunt, the fire hose that has lining, larynx hoop, big or small pipe adapter, straight pipe, connects snap ring, tensimeter, spigot-and-socket adapter tower seat, pressure regulator valve, venting valve, transparent pressure-resistant plastic flexible pipe soon, flattens formula flow regulator and stainless-steel tube etc., when sampling, first to carry out assembling and on-the-spot installation of sample collecting apparatus, assemble and install kit used and consumptive material and comprise screwdriver, pipe wrench, spanner, raw material band, PVC glue, angle grinding machine etc.
The assembling mode of sample collecting apparatus is: the port one of sample collection four-way adopts inserted type quick coupling and four-way shunt to join; The port two-way of sample collection four-way is crossed screwed connection tensimeter; The port threeway of sample collection four-way is crossed screwed connection spigot-and-socket and is taken over tower seat, and spigot-and-socket is taken over one end of the other end connection transparent plastic hose of tower seat, outside solid with larynx banding; Transparent plastic hose is sleeved in flattening formula flow regulator, and the other end is fastened on one end of stainless-steel tube with larynx hoop; The port four-way of sample collection four-way is crossed screwed connection spigot-and-socket and is taken over tower seat, and spigot-and-socket is taken over one end of the other end connection transparent plastic hose of tower seat, outside solid with larynx banding; The other end of transparent plastic hose is fastened on one end of spigot-and-socket adapter tower seat with larynx hoop, spigot-and-socket is taken over the other end of tower seat by screwed connection pressure regulator valve.
The problem that traditional acquisition mode of Organic Pollution water sample exists is:
(1) fire hose using in sample collecting apparatus, transparent pressure-resistant plastic flexible pipe, raw material band etc. are contaminated samples easily, makes sample distortion; Particularly, in initial use procedure several times, the objectionable constituent that material therefor discharges can produce a very large impact the quality of sample, contaminated samples.
(2) parts of sample collecting apparatus are many, form complexity, and general assembly (TW) is greater than 80kg, bulky, carries inconvenience.
(3) Assembling program complexity, complex operation, consuming time longer.Part parts adopt American Standard, are unfavorable for connection each other, operation inconvenience.
(4) easily produce cavitation at flow through turning round of pipeline and reducing position of sample collection four-way and sample, in the time that the vacuum tightness in air pocket is greater than the saturated vapor pressure of some volatile matter in water or half volatile material, can cause overflowing of these volatility or half volatile material lost, make sample distortion.
(5) water flow adopts " flattening formula " flow regulator control, when adjust flux, the streamline bundle of water gradually becomes " flat " shape by " cylinder " shape, change the shape of streamline bundle, increase the probability of intermolecular mutual collision, the volatilization in Organic Pollution water sample, the probability that half volatile material is separated out are increased.
(6) when pump head or power are when larger, due to the reacting force of mouth of pipe water outlet, can cause the venting valve that is arranged on fire hose head to swing, as not firm in controlled, can to operating personnel and around object produce to clash into and threaten.
(7) maximum specification of the suction pump mouth of pipe that sample collecting apparatus can dock is DN100, is greater than the pump line of this specification for scene, can not carry out sampling operation because docking.
(8) aquifer yield of the terminal stainless-steel tube of raw sample harvester is too little, sample collection overlong time, make the duration of contact of water sample and air longer, so both easily made volatilization, half volatile material in water sample scatter and disappear, easily make again the reducing substances in water sample oxidized, cause sample distortion.

Principle of work of the present utility model is: the cannula assembly first current stabilization separator tube front end being fixedly connected with inserts in pollution water sample output pump line, and current stabilization separator tube is tied up and is fixed on pump line with rope etc.After rear pump work, the water outlet of pump line mouth enters in current stabilization separator tube 21 by cannula assembly, regulates shunting pressure regulator valve, and the reading that makes tensimeter 7 is 0.18~0.2MPa; Grasp concentric type flow regulator, stretching sampling flexible pipe 1, makes its water delivering orifice upward, exceeds the end face 800mm of current stabilization separator tube 21 and is erectility; Slowly regulate concentric type flow regulator, the water polo face height of flexible pipe 1 water outlet that makes to sample is less than 5mm, and the flexible pipe 1 of guaranteeing to sample is inner and the current of water outlet in lose bubble; The water delivering orifice of sampling flexible pipe 1 is slowly inserted in the sampling bottle (for the sample collection containing half volatile material) of 2000ml, until the water side of sampling flexible pipe 1 is about 5~8mm with bottle end distance, place motionlessly, when the water surface is from the about 50mm of bottleneck distance in bottle, slowly propose sampling flexible pipe 1.Carrying in pipe process, ensure that the water delivering orifice of sampling flexible pipe 1 and the water surface distance in bottle are not more than 5mm, until sampling bottle is filled water sample.Finally tighten bottle cap, be inverted micro-striking, in bottle, without Bubble formation, complete the collecting work of large bottle sample.
While gathering the pollution water sample that contains volatile matter, the flexible pipe 1 of sampling slowly inserts in sampling bottle (2 40ml), along with the continuous rising of the water surface in bottle, slowly promote sampling flexible pipe 1, carry in pipe process, the water delivering orifice and the water surface distance that ensure sampling flexible pipe 1 are not more than 5mm, until fill water sample, tighten bottle cap, be inverted micro-striking, in bottle, without Bubble formation, complete sample collection.
The utility model also can be used for the collection of other water sample.
