Abstract
The utility model discloses the energy-conservation water washing device of a kind of PVB, it relates to industrial PVB water wash system technical field.It comprises PVA dissolution kettle, filtration unit, cooling plate, PVA condensation kettle and washing kettle, and PVA dissolution kettle is connected with filtration unit, and filtration unit is connected with cooling plate, and cooling plate connects PVA condensation kettle, and PVA condensation kettle is connected with washing kettle; Two steps of the step that described cooling plate is lowered the temperature by pure water and ethylene glycol cooling form, and filtration unit, a step, two steps, PVA condensation kettle connect successively, is a step by pure water tank? be connected with washing kettle.The utility model realizes the second stage employ of pure water, reaches the target of energy-saving and water-saving, and reduces production cost, increases the benefit, is easy to promote the use of.
Description
Technical field
The utility model relates to industrial PVB water wash system technical field, be specifically related to the energy-conservation water washing device of PVB.
Background technology
At present, water washing device in producing for PVB is mainly 1 st pure water with water, and the pure water temperature meeting washing requirement also needs to reach 40 DEG C through steam heating, just can be used for the washing of condensation output PVB, its idiographic flow is: pure water is through being steam heated to 40 DEG C, be input in PVB washing kettle through piping and PVB is washed, waste water enters sewage plant through pipeline, because water temperature needs to reach specified temperature, and waste water COD is higher, so not reusable edible, a large amount of consumption is caused to water resources and thermal resource, based on this, design the energy-conservation water washing device of a kind of novel PVB or necessary.
Summary of the invention
For the deficiency that prior art exists, the utility model object is to provide the energy-conservation water washing device of a kind of PVB, and structure is simple, reasonable in design, realize the second stage employ of pure water, reach the target of energy-saving and water-saving, and reduction production cost, increase the benefit, be easy to promote the use of.
To achieve these goals, the utility model realizes by the following technical solutions: the energy-conservation water washing device of PVB, comprise PVA dissolution kettle, filtration unit, cooling plate, PVA condensation kettle and washing kettle, PVA dissolution kettle is connected with filtration unit, filtration unit is connected with cooling plate, cooling plate connects PVA condensation kettle, and PVA condensation kettle is connected with washing kettle.
As preferably, two steps of the step that described cooling plate is lowered the temperature by pure water and ethylene glycol cooling form, and filtration unit, a step, two steps, PVA condensation kettle connect successively, and a step is connected with washing kettle by pure water tank.
The beneficial effects of the utility model: the pure water after being used by collection one-level cooling plate, to pure water tank, is used further to washing, realizes the effect of energy-saving and water-saving, while guarantee quality product, effectively reduce the consumption of water resources and heat energy, reduce production cost, increase the benefit.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structured flowchart of the present utility model.
Embodiment
The technique means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
With reference to Fig. 1, this embodiment is by the following technical solutions: the energy-conservation water washing device of PVB, comprise PVA dissolution kettle 1, filtration unit 2, cooling plate 3, PVA condensation kettle 4 and washing kettle 5, PVA dissolution kettle 1, filtration unit 2, cooling plate 3, PVA condensation kettle 4, washing kettle 5 connect successively; Described cooling plate 3 is made up of a step 6 and two steps 7, and a step 6 is pure water cooling, and two steps 7 are ethylene glycol cooling, and filtration unit 2, step 6, two step 7, PVA condensation kettle 4 connect successively, and a step 6 is connected with washing kettle 5 by pure water tank 8.
When this embodiment uses, its principle of work is: the PVA solution temperature of having dissolved reaches 80 DEG C, be cooled to about 10 DEG C through cooling plate 3 to carry out condensation reaction and be warming up to about 68 DEG C generations PVB, PVB and be cooled to about 42 DEG C through ethylene glycol and enter washing kettle and wash; Above-mentioned cooling plate 3 is divided into step 6 and two steps 7, one step 6 is pure water cooling, two steps 7 are ethylene glycol cooling, what be connected with a step 6 also has a pure water tank 8, and pure water tank 8 is connected with washing kettle 5 again, and pure water tank 5 is for storing used pure water in a step 6, this pure water is through absorbing the heat of PVA solution, temperature is about 40 DEG C, basically identical with water temperature needed for water scouring water, can be used for washing; In one step 6, used pure water flows into pure water tank 8 and stores, then enters washing kettle 5 couples of PVB and wash, and so just achieves the recycling of second pure water, thus has saved ample resources.
This embodiment overcomes the deficiencies in the prior art, a kind of water is provided to provide the energy-conservation water washing device of PVB of two secondary rings utilizations, this device by installing pure water tank additional and store second pure water and for the washing of PVB between one-level cooling plate and washing kettle, can economize on resources in a large number, reduce production cost, realize energy-saving and emission-reduction, increase the benefit, there is wide market application foreground.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
