Abstract
The invention relates to a falling film evaporator distribution disc with a folding edge. The falling film evaporator distribution disc comprises a porous plate substrate, an enclosing plate welded on the edge of the substrate, and a handle welded on the enclosing plate, wherein the substrate comprises a round bottom plate and an upward-folding folding edge on the edge of the bottom plate, the folding edge comprises an arc section and a straight edge transition section, the enclosing plate and the straight edge transition section are welded, and uniformly-distributed material holes are arranged on the bottom plate. The falling film evaporator distribution disc has characteristics of simple structure and easy manufacture. With the falling film evaporator distribution disc, the deformation problem of the porous plate during the manufacturing welding process can be completely solved, the flatness of the multiple holes is ensured, and the uniform material distribution of the evaporator during the operating process is ensured.
Description
Technical field
The invention relates to and improve JMZ falling film evaporator feed liquid distribution plate, belong to mechanical equipment technical field.
Background technology
Falling film evaporator material distribution plate, as the core component of falling film evaporator cloth system, it is that a porous flat plate and coaming plate are formed, cloth hole site just in time crisscrosses between heating tube tubulation, its Main Function material is distributed to uniformly each root heat exchanger tube and to ensure in every root heat exchanger tube that feed liquid is membranaceously to flow downward along tube wall, but porous plate directly welds with coaming plate in the fabrication process, generation due to welding stress very easily makes porous plate be out of shape, cause feed liquid maldistribution in evaporation process, feed liquid is made to produce bias current in heat exchanger tube, fouling is produced time serious, coking, the serious consequence even blocked.
Summary of the invention
The present invention in order to overcome above-mentioned deficiency, providing one and effectively preventing welding deformation just, improves the band flange falling film evaporator distribution plate of feed liquid assignment accuracy.
For realizing the object of the invention, provide following technical scheme: a kind of band flange falling film evaporator distribution plate, comprise perforated plate base, be welded in the coaming plate of matrix border and be welded in the handle on coaming plate, it is characterized in that the flange that described matrix comprises circular bottom plate and bottom edge and upwards turns down, described flange comprises arc section and straight flange changeover portion, described coaming plate welds with straight flange changeover portion, base plate offers uniform material hole.
As preferably, described arc section radius is 30 ~ 50mm.
As preferably, described arc section inwall is provided with reinforcement.
Main innovation is porous plate first to carry out flange after blanking, and the changeover portion making flat board rout up a circular arc and a bit of straight flange welds with coaming plate again, to control plate deformation amount, then carries out drilling operation on flat board.Due to flange changeover portion, flat board after welding deflection significantly reduces, and it manufactures thickness and also declines to some extent simultaneously.
Beneficial effect of the present invention: structure of the present invention is simple, easily manufactured, thoroughly solving porous plate manufacturing the problem on deformation produced in welding process, ensure that the flatness of porous, ensure that the uniform distribution of evaporimeter in running.
