Because adopt above technical scheme, the utility model has more perfectly been realized goal of the invention, it is simple in structure, the efficient height, and cost is low, can handle relatively large solvent slop continuously and does not need deslagging.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The concrete structure of the utility model evaporimeter is, shell is by the steel ellipse head, cylinder and awl bucket constitute, evaporimeter is from top to bottom successively by evaporator section 5, bringing-up section 8, sedimentation bucket 12 is formed, evaporator section 5 is mainly gas-phase space, the solvent place that vaporization separates with the vapour foam is provided, be provided with solvent slop import 16 in the bottom of evaporator section 5, clean solvent vapo(u)r outlet 3 is located at the top of evaporator section 5, and near clean solvent vapo(u)r outlet 3, be provided with the foam removal net, evaporator section 5 tops are provided with nozzle for thermometer 1 and vacuum meter takes over 4, for safety, operation is stopped up and is met accident behind the preventer, the top is provided with flame-arrester vent plug 2, is provided with to observe liquid level visor 7 on evaporator section 5, maintenance hand hole 6; Bringing-up section 8 is for having the steel tubular heat exchanger of certain heat transfer area, difference is, tubulation is not of uniform size to be caused, it is inconsistent to be convenient to be subjected to thermal material to be heated, form different severe, realize Natural Circulation, on bringing-up section 8, be provided with heating agent import and export 15, heating element insertion mouth 10, and in bringing-up section 8, being provided with big tubulation 9, little tubulation 14, big tubulation 9 is evenly to arrange with little tubulation 14.The heating agent conduction oil places between the tubulation, and thermoelectric heating device inserts mouthful 10 insertions wherein by heating element; The effect of sedimentation bucket 12 provides enough spaces and gathers residue and be convenient to discharge residue, is provided with manhole 11 on sedimentation bucket 12, and the bottom of sedimentation bucket 12 is provided with slag notch 13; Big tubulation 9, little tubulation 14 communicate with evaporator section 5 and sedimentation bucket 12.
The course of work of the present utility model is: the solvent slop that needs to handle enters between the condensate cooler pipe, carry out entering in the evaporimeter of negative pressure along solvent slop import 16 after heat exchange improves temperature with the hot solvent steam that comes out from evaporimeter epimere evaporator section 5 tops in the pipe, and import by conduit in the big tubulation 9 of bringing-up section 8 in the evaporimeter, charging is by the liquid level ball float control of indoor connection charging aperture; Because temperature is lower, descends along big tubulation 9, and be heated, rise along little tubulation 14, be heated to boiling, vaporization rapidly, the solvent vapour of vaporization is after the foam separation is caught at the evaporimeter top, go out evaporimeter from the end socket top, enter in the condensate cooler pipe, quilt enters condensate cooler after being managed the lower solvent slop partial condensation cooling of outer temperature again, further be cooled to room temperature by the outer cooling water adverse current of pipe, and be collected in the vacuum groove; Nonvolatile component such as resin, powder, pigment, residue, the space turbulence of middle and lower part liquid phase, circulation in evaporimeter, along with increasing of solvent slop treating capacity, concentration, viscosity are cumulative, again because the awl bucket can hold a certain amount of residue, so evaporimeter is a collection of can be handled relatively large solvent slop continuously and not need deslagging, when wanting deslagging, stop heating, strengthen vacuum, make in the residue residual solvent by self (residual oil temperature), heat further gasifies, simultaneously, residue and conduction oil temperature drop are to certain temperature, (conduction oil temperature and residue temperature are more or less the same); Shut down, open the awl end residual cake valve next day to normal temperature, can make residue be flow regime gravity flow deslagging, and do not need by hand or mechanical deslagging; After residue had been arranged, charging again realized the lower whorl cycling.
This evaporimeter has following characteristics;
