Drip loss late it is higher when, cooling tower rate of water make-up is more, and the part water droplet having been cooled by is pulled away will cause effective heat transfer rate
Loss and the drop loss late of floaing for declining, therefore strictly controlling cooling tower are water-saving important means to be needed first to reach the purpose
The accurate drop loss late of floaing for measuring cooling tower, the only magnitude accurately measure, and the mechanism of cooling tower could effectively be instructed to improve, into
And research and develop more energy-efficient cooling tower class product.
But the accurate measurement for drop loss of floaing is always a problem, in the prior art, by following several method：1）Filter
Paper moisture absorption method：Filter paper plane is vertical with test point air-flow direction, and filter paper uses the middling speed moisture absorption filter paper of chemical experiment.It uses
In, it is blown brokenly by hot wet wind because filter paper is easy and filter paper reaches the factors such as saturation no longer water suction in humidity exposure time, can cause to measure
As a result less than normal.2）Collect method of testing：In away from tower at about 1.5 meters of main sink, using the method for dividing iso-area circlet, along four masters
Sink line（Orthogonal diameter）Arrange 18 ring measuring points, about 1.5 meters of place's samplings on the right side of the line of rabbet joint.Collection method test is multiple
It is miscellaneous, and and actual value deviation it is big.
Invention content
The purpose of the utility model is to overcome disadvantage existing in the prior art, one kind is provided and is floatd and drips collection measurement dress
It sets, the aqueous wind being discharged in cooling tower is passed through the device, water droplet will be under the effect of gravity through stream after collecting on the tube wall of air duct
Road enters in container, and measuring container can be done directly the metering for drop amount of floaing, without going to laboratory to weigh, the technical solution of use
It is：A kind of power plant cooling tower drop collection measuring device of floaing, including acquisition portion and measurement portion, between the acquisition portion and measurement portion
If runner, it is characterised in that：The acquisition portion includes shell, and air duct is set in the shell, and the air duct has to be connected with air inlet
The wind inlet section connect also has the wind outlet section that connect with air outlet, is confluence section between wind inlet section and wind outlet section, the confluence section and
Runner is connected to.
The technical characteristics of the utility model also has：The confluence section is the lowest segment in entire air duct.
The technical characteristics of the utility model also has：The measurement portion includes measuring container, and the measuring container, which is equipped with, to be carved
Degree.
The technical characteristics of the utility model also has：The runner sets discharging valve close to the end of measuring container.
The technical characteristics of the utility model also has：The air duct is V-type air duct.
The technical characteristics of the utility model also has：The air duct is three-layer type air duct, air inlet of the every layer of air duct on shell
Open height is different, is all provided with that there are three above air tunnel branch in every layer of air duct.
The technical characteristics of the utility model also has：Air tunnel branch in every layer of air duct is four.
The beneficial effects of the utility model are：The present apparatus design both ends high, middle low air duct convenient for condensed water to
Runner collects, and simplifies collection method, improves the accuracy of test result；The present apparatus is used multiple times, and is inhaled compared to filter paper
Receipts method, saves cost；The present apparatus saves laboratory and weighs link, reduce manpower and disappear compared to traditional collection method of testing
Consumption；The present apparatus has the advantages that simple in structure, at low cost, test result precision height.
Description of the drawings
Attached drawing 1 is the utility model structure diagram, and attached drawing 2 is the utility model scheme of installation, wherein 1 is shell, 2
It is air inlet, 3 be air outlet, and 4 be air duct, and 5 be measuring container, and 6 be discharging valve, and 7 be runner, and 8 be diversion pipe, and 9 be cross,
10 be air outlet of cooling tower.
Specific implementation mode
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is illustrated.The utility model discloses one kind
Power plant cooling tower collects measuring device with drop of floaing, which includes acquisition portion and measurement portion, acquisition portion and measurement portion
Between set runner.Acquisition portion includes shell 1, and air duct 4 is set in shell 1, and air duct 4 has the wind inlet section being connect with air inlet 2, also has
There is the wind outlet section being connect with air outlet 3, is confluence section between wind inlet section and wind outlet section, confluence section is connected to runner 7, it is contemplated that water
Flow feature, the confluence section of the present apparatus is the lowest segment in entire air duct 4.In this way, when wind from air inlet 2 enter shell 1 and from
When air outlet 3 flows outwardly, it is therein float drip be pooled to confluence section in, discharged through runner.
The measurement portion of the present apparatus includes measuring container 5, and measuring container 5 is equipped with scale, in order to observe and measurement is floatd drop
Water, runner 7 set discharging valve 6 close to the end of measuring container 5, discharging valve 6 are opened after test, waterproof is to graduated
In measuring container, the link that laboratory is weighed is avoided.
In the embodiment of the present apparatus, V-type air duct is in the air duct used；Air duct uses three-layer type air duct, and every layer of air duct exists
Air inlet open height on shell is different, is all provided with that there are three above air tunnel branch in every layer of air duct；To increase connecing for wind and air duct
Contacting surface is accumulated, and the air tunnel branch in every layer of air duct is four, certainly can also be more, enough air duct tube walls and the wind for carrying drop of floaing
Contact area increase so that drop collection is more abundant.
By taking mechanical draft formula cooling tower as an example, as shown in Fig. 2, the present apparatus is horizontally fixed on cross 9, the present apparatus into
