Description
Technical field
The utility model belongs to PEPA production equipment field, specifically a kind of PEPA process steam retracting device.
Background technology
PEPA, organic matter, normally by Dicarboxylic Acids (acid anhydrides or ester) and polyalcohol (comprising glycol) condensation (or ester exchange) or be polymerized by lactone and polyalcohol.Binary acid has phthalic acid or phthalate anhydride or its ester, adipic acid, halogeno-benzene dioctyl phthalate etc.Polyalcohol has ethylene glycol, propane diols, diglycol, trimethylolpropane, pentaerythrite etc.The PEPA of different cultivars due to kind difference or preparation technology different, character is also different, is hydroxyl value, acid number, moisture, viscosity, molecular weight, density and colourity etc. for the important several indexs of PEPA.The characteristic of PEPA and purposes: ester group, amino isopolarity group that PAUR is more because molecule contains, cohesive strength and strong adhesion, have higher intensity, wearability.
When PEPA is produced in regeneration, need to heat material, heating conventionally adopts steam and heats, and the hot water after heating and a part of water vapour be discharge directly, thereby thermal loss is very serious.
Summary of the invention
The purpose of this utility model is the deficiency existing in above-mentioned technology, proposes a kind of PEPA process steam retracting device.
The utility model provides following technical scheme:
PEPA process steam retracting device, it comprises material reaction tank body, in material reaction tank body, be provided with rabbling mechanism and be located at the inlet pipe of material reaction tank body side, material reaction tank body side is also provided with out pipe, go out pipe and be connected with steam-water separator by pump, steam-water separator bottom is provided with water pipe and is connected with material preheating tank body.
Steam-water separator top is provided with tracheae and is connected with raw material preheating tank body.
The utility model has the advantages that simple in structurely, can make full use of the heat of steam and hot water, energy-saving and emission-reduction, have improved benefit and production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, PEPA process steam retracting device, it comprises material reaction tank body 1, in material reaction tank body 1, be provided with rabbling mechanism 2 and be located at the inlet pipe 3 of material reaction tank body 1 side, material reaction tank body 1 side is also provided with out pipe 4, go out pipe and 4 be connected with steam-water separator 6 by pump 5, at the bottom of steam-water separator, 6 are provided with water pipe 7 and are connected with material preheating tank body 8, and steam-water separator 6 tops are provided with tracheae 9 and are connected with raw material preheating tank body 10.
When the utility model work, in material reaction body 1, pass into steam heating by inlet pipe 3, make material reaction temperature at 230 ℃, part water vapour and hot water flow to steam-water separator by going out pipe 4, hot water is in the bottom of steam-water separator, steam is on the top of steam-water separator, hot water is delivered to material preheating tank body by water pipe material is shifted to an earlier date to preheating, its temperature is carried to 100 ℃ of left and right, reduce like this material and entered the heat time of material reaction tank body and add heat, made full use of heat; Steam is delivered to raw material preheating tank body by tracheae simultaneously, in advance raw material is carried out to preheating.
Claims (2)
1. PEPA process steam retracting device, it comprises material reaction tank body, in material reaction tank body, be provided with rabbling mechanism and be located at the inlet pipe of material reaction tank body side, material reaction tank body side is also provided with out pipe, go out pipe and be connected with steam-water separator by pump, steam-water separator bottom is provided with water pipe and is connected with material preheating tank body.
2. PEPA process steam retracting device according to claim 1, is characterized in that: steam-water separator top is provided with tracheae and is connected with raw material preheating tank body.
