Description

A kind of COD reflux condensation mode can washing apparatus
Technical field
This utility model is related to a kind of COD reflux condensation mode can washing apparatus.
Background technology
COD, as common environmental factors, during laboratory batch detection, is typically titrated using potassium dichromate method Measure, its defect is:One is the batch reflux condensate device needing to use, and connects water cooling from the beginning because this device is long-term, cold Solidifying inside pipe wall is easily enriched with filemot incrustation scale and microorganism, especially summer, and microbial growth speed is fast, can produce a large amount of Moss, both affected overall attractive in appearance, occupied condensing tube pipeline space again, and so that water flow in pipeline is reduced, had a strong impact on condensation effect Really, lead to COD result higher;Two is that titration produces substantial amounts of acid pickle;
In real work, sample size is larger, needs to ensure the cleaning of condensing units, improves the condensation effect of condensed water, Improve the accuracy that COD measures, but all the time, have no a kind of low cost, simple to operate, the having of the good cleaning method of effect Close report.
Utility model content
This utility model provides a kind of COD reflux condensation mode can washing apparatus, and this device recycling has detected COD's Acid pickle carries out cleaning condensation pipeline, improves the condensation effect of reflux condensation mode water, thus improving the accurate of COD mensure Property.
In order to solve the above problems, this utility model be employed technical scheme comprise that a kind of such, COD reflux condensing tube Cleaning device, including the iron stand being placed in laboratory table, spacing side by side is fixed on the N number of condensing tube on iron stand, wherein, N >= 2, from the beginning of outermost condensing tube, the connector of its outer tube upper end pass through the first silica gel tube with outside next adjacent condensing tube The connector of pipe lower end is connected, and connects according to this, until the connector of penultimate condensing tube outer tube upper end passes through N-1 silica gel Pipe is connected with the connector of another side outermost condensing tube outer tube lower end, under the outermost condensing tube outer tube not being connected with silica gel tube The connector at end is connected with a two-way pipe joint, leads up to connecting tube and liquid waste collector phase in this two-way pipe joint Even, this liquid waste collector height is higher than condensing tube the top 30-50cm, separately leads up to water inlet pipe and water in two-way pipe joint Tap is connected, and the connector of the outermost condensing tube outer tube upper end not being connected with silica gel tube is connected with waste liquid pool by outlet pipe, It is respectively arranged with pipe clamp on described water inlet pipe and outlet pipe.
Preferably, described liquid waste collector passes through bracing frame institute support.
Preferably, described condensing tube is spherical condensation tube.
Beneficial effect:1st, improve condensation effect, cleaned by acid pickle, the moss in condensing tube and fouling are rinsed dry Only, simple to operation in real work, cleaning performance is good, improves condensation effect.
2nd, improve the accuracy of COD result:The method cleaned by acid pickle, while improving condensation effect, can To improve the accuracy of COD result.
3rd, saved cleaning cost:The recycling to acid pickle for this utility model, reagent zero cost, save cleaning The consumption of agent, saves laboratory cost.
Brief description
Fig. 1 is this utility model structural representation.
Specific embodiment
In order to deepen, to understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, this utility model to be made further Describe in detail, this embodiment is only used for explaining this utility model, does not constitute the restriction to this utility model protection domain.
Referring to Fig. 1, a kind of COD reflux condensation mode can washing apparatus, including the iron stand 2 being placed in laboratory table 1, spacing side by side It is fixed on 6 condensing tubes 5 on iron stand, from the beginning of outermost condensing tube, the connector of its outer tube upper end passes through first Silica gel tube 6 is connected with the connector of next adjacent condensing tube outer tube lower end, connects according to this, until outside penultimate condensing tube The connector of pipe upper end is connected with the connector of another side outermost condensing tube outer tube lower end, not with silica gel by the 5th silica gel tube The connector of the outermost condensing tube outer tube lower end that pipe is connected is connected with a two-way pipe joint, this two-way pipe joint Zhong mono- tunnel It is connected with liquid waste collector 8 by connecting tube, this liquid waste collector 8 height is higher than condensing tube the top 30-50cm, bipass connects Head in separately lead up to water inlet pipe 10 and faucet(Not shown in fig. 1)It is connected, the outermost not being connected with silica gel tube The connector of condensing tube outer tube upper end passes through outlet pipe 11 and waste liquid pool(Not shown in fig. 1)Connected, described water inlet pipe With pipe clamp 9 is respectively arranged with outlet pipe.Preferably, described liquid waste collector 8 passes through bracing frame(Not shown in the accompanying drawings) Institute's support, described condensing tube 5 is spherical condensation tube.
When carrying out detecting its COD to water sample, on the basis of said apparatus, the top of each condensing tube 5 is provided with The seal closure 7 of the upper end of one sealed condensating pipe, the lower section of each condensing tube 5 is provided with a ground conical flask 4, each mill It is provided with an adjustable electric furnace 3, the lower end of described condensing tube 4 is stretched in ground conical flask 4, this ground below mouth conical flask Conical flask 4 is placed on adjustable electric furnace 3, and adjustable electric furnace 3 is placed in laboratory table 1;
