Description
[technical field]
The utility model relates to a kind of evaporimeter, especially relates to the evaporimeter that a kind of high-purity isoquinolin is produced.
[background technology]
The distributor kind of falling film evaporator is more, traditional distributor be broadly divided into overflow type and plug-in type (flow guiding type) etc.Wherein overflow type is simple in structure, and the operating flexibility of processing, high, the difficult obstruction of installation accuracy, cloth liquid is big, guarantees but the distribution effect is difficult, is applicable to the less demanding occasion that distributes; Plug-in type can guarantee that generally liquid cloth film in single tube is even; And be difficult for guaranteeing that liquid is evenly distributed on all heat exchanger tubes, and flow resistance is big, is prone to stop up; Processing, installation requirement height; Be suitable for handling the small-sized falling film evaporator of cleaning material, and all be not suitable for the evaporimeter that high-purity isoquinolin is produced, therefore be necessary to improve.
[utility model content]
The technical problem that the utility model solves provides the evaporimeter that a kind of high-purity isoquinolin is produced; The disc type distributor that is provided with in it is made up of initial distribution device and distributing disc group; The initial distribution device is realized the initial distribution of feed liquid; Have sieve aperture according to certain rules on the sieve plate of distributing disc bottom, the feed liquid sieve aperture of flowing through is realized the multiple spot cloth, reaches equally distributed purpose.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopts is: the evaporimeter that high-purity isoquinolin is produced, comprise feed pipe, end socket, disc type distributor and downspout, and said feed pipe is connected with disc type distributor one end through end socket; The said disc type distributor other end is connected with downspout; Said disc type distributor is made up of initial distribution device and distributing disc group, and said initial distribution device is made up of dispersion impeller and back-up ring, and said distributing disc group is made up of a plurality of porous sieve plate distributing discs.
Wherein, said porous sieve plate distributing disc is made up of last distributing disc, middle distributing disc and following distributing disc, saidly goes up distributing disc, middle distributing disc (and the spacing between the following distributing disc is by the distance sink tube location and fixed by the support bolt bottom.
Further, the said sieve aperture of going up on distributing disc, middle distributing disc and the following distributing disc is staggeredly arranged.
Further; It is said that upward distributing disc is identical with the pattern of middle distributing disc; All being equilateral triangle arranges; But the pitch of holes that staggers each other half, the hole on the said distributing disc down is regular hexagon arranges, and makes each downspout have six bursts of flows to fall realization to downspout multiple spot cloth from following distributing disc sieve aperture on every side.
Compared with prior art cloth liquid is even for the utility model, and is simple in structure, and processing, easy for installation, less scaling is convenient to clean, and stable operation is reliable, is particularly suitable for big flow operation.

Accompanying drawing described herein is the further understanding that is used to provide the utility model, constitutes the application's a part, but do not constitute improper qualification the utility model, in the accompanying drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 be between each distributing disc of the utility model sieve aperture with position view.
Description of reference numerals: 1-feed pipe; The 2-end socket; The 3-back-up ring; The 4-dispersion impeller; The last distributing disc of 5-; Distributing disc among the 6-; Distributing disc under the 7-; The 8-distance sink tube; 9-supports bolt; The 10-downspout.
[specific embodiment]
The embodiment of the utility model is described below.
The evaporimeter that high-purity isoquinolin is produced; Comprise feed pipe 1, end socket 2, disc type distributor and downspout 10; Said feed pipe 1 is connected with disc type distributor one end through end socket 2, and the said disc type distributor other end is connected with downspout 10, and said disc type distributor is made up of initial distribution device and distributing disc group; Said initial distribution device is made up of dispersion impeller 4 and back-up ring 3, and said distributing disc dish group is made up of a plurality of porous sieve plate distributing discs.Said porous sieve plate distributing disc is made up of last distributing disc 5, middle distributing disc 6 and following distributing disc 7, saidly goes up spacing between distributing disc 5, middle distributing disc 6 and the following distributing disc 7 by distance sink tube 8 location and fix by supporting bolt 9 bottom.
In the design of disc type distributor, the pattern on the porous sieve plate distributing disc is extremely important to the performance of distributor.In general, the arrangement mode of the downspout on pattern and the falling film evaporator tube sheet is relevant, and feed liquid can be fallen on the slab bridge of tube sheet when sieve aperture falls from last distributing disc.When a plurality of distributing disc is arranged, should make that sieve aperture staggers mutually between each dish.When flow one timing, if perforate is many more, then the aperture is more little, is prone to stop up less being advisable in suggestion cloth hole.The said sieve aperture of going up on distributing disc 5, middle distributing disc 6 and the following distributing disc 7 is staggeredly arranged, and is as shown in Figure 2, following distributing disc hole 11; Last distributing disc hole 12, middle distributing disc hole 13, specifically; It is said that upward distributing disc 5 is identical with the pattern of middle distributing disc 6, and all be equilateral triangle and arrange, but the pitch of holes that staggers each other half; Hole on the said distributing disc 7 down is regular hexagon arranges, and makes each downspout 10 have six bursts of flows to fall realization to downspout 10 multiple spot clothes from following distributing disc 7 sieve apertures on every side.When low discharge was operated, for preventing to stop up sieve aperture, suggestion was cancelled the more following distributing disc 7 in cloth hole and is become two dish distributors.
The manufacturing of disc type distributor and installation quality have very big influence to cloth film effect.For making the disc type distributor obtain good performance, to guarantee that in manufacture process tube sheet and porous sieve plate distributing disc are smooth and keep good flatness and rigidity.Little sieve aperture will be done chamfered on the distributing disc, and burr must not be arranged, so that feed liquid can evenly flow on dish, prevents sieve aperture extension dirt.During installation, utilize specific purpose tool to make tube sheet and distributing disc sieve plate maintenance level.In a word, when only all being guaranteed, just can make distributor be able to stable operation, reach the purpose of even cloth film at aspects such as design, manufacturing, installation and operations.
Operation principle: during operation; Feed liquid gets into the slot overflow of dispersion impeller 4 backs from dispersion impeller 4 from feed pipe 1; Fall on the distributing disc 5 through the annular space of 3 of dispersion impeller 4 and back-up rings and to accomplish initial distribution, distributing disc 6 is fallen on the slab bridge of tube sheet with the sieve plate on the following distributing disc 7 in flowing through respectively again, and downspout 10 is gone in overflow; Wall is membranaceous and flows down within it, reaches the purpose of even cloth film.
The above in the spiritual category that does not break away from the utility model creation, is familiar with the protection domain that this technological various simple covert and modification that those skilled in the art did still belongs to the utility model only in order to the convenient the utility model of explaining.
