Abstract
The utility model relates to an exchange tower for a fluid bed desalting equipment. The utility model is composed of a tower body and a support frame, characterized in that the tower body is provided with a positive resin outlet, a positive resin inlet, a negative resin inlet and a negative resin outlet from up to bottom. Because the heights of the positive and negative resin inlets of the utility model are crossed, the positive and negative resins in the tower body form respective independent resin layers and a mixing region as well, which is favorable for thorough desalting; the height of the tower body is reduced, and the utilization ratio of the space in the tower is increased. The utility model has reasonable and simple structure, the fluid bed desalting equipment assembled in the center can be used continuously in long term, and the utility model is suitable for occasions continuously requiring the supply of desalted water.
Description
The utility model relates to device used in a kind of water treating equipment, particularly a kind of exchange column that is used for the thermopnore demineralization plant.
At present, with ion exchange method water quality being carried out the desalination processing generally adopts fixed bed unit to carry out, this equipment is that two kinds of resins of phase blended positive and negative are housed in a container, former water flows through just it is exchanged desalination, water recoils to resin after the resin of working is saturated, utilize two kinds of resins of positive and negative varying in weight and two kinds of resin isolation are come in water, respectively two kinds of resins are carried out manipulation of regeneration then, again two kinds of mixed with resin are got up afterwards and come into operation again.This equipment regeneration wash procedure complexity operate loaded down with trivial detailsly, handles former water and intermittently carries out, and can not move continuously for a long time, and the resin utilization ratio is low, and on average the water treatment amount is low.
The purpose of this utility model is to provide a kind of exchange column, and it is used for the thermopnore demineralization plant, is connected in series mutually with two cover regeneration, cleaning tower respectively, forms the thermopnore demineralization plant of continuously-running.
The utility model as shown in Figure 1, include tower body (1), support (2), wherein tower body (1) upper end is provided with for the effusive water outlet of de-mineralized water (11), bottom and is provided with the water-in (16) that flows into for former water, and principal feature of the present utility model is that tower body (1) is provided with positive resin outlet (15), negative resin import (14), positive resin inlet (13), negative resin outlet (12) from bottom to top successively.When the utility model was fit into whole plant, positive resin inlet (13) exported (15) with positive resin and is connected with the positive resin regeneration of a cover, cleaning tower, and negative resin import (14), negative resin outlet (12) are connected with a cover negative resin regeneration, cleaning tower; Be filled with two kinds of ion exchange resin of positive and negative in the tower body (1), because positive and negative weight resin difference, the sun resin is heavier than negative resin, so sink at flow state Xiayang resin (3), mainly be distributed in positive resin inlet (13) with lower area, and negative resin (5) come-up mainly is distributed in the above zone of negative resin import (14), because positive resin inlet (13) is more than negative resin import (14), so the positive and negative resin has one section mixing zone (4).During work, former water enters from bottom to top operation in the tower by water-in (16), former water at first contacts with positive resin (3), remove a part of positively charged ion, rise to positive and negative mixed with resin district (4) then, owing to carry out positive and negative ion-exchange simultaneously, the positive and negative ion in the water is removed simultaneously in this zone, therefore do not exist the ion exchange process gegenion to suppress the phenomenon that exchange is carried out to the desalination direction, the permutoid reaction of desalination is carried out thoroughly; After the negative resin layer (5) that water rises to top again carries out last anion exchange reaction, become the de-mineralized water that does not contain ionic impurity, flow out by water outlet (11).In this process, mobile sun resin is saturated substantially when arriving orlop from top to bottom, flow out from positive resin outlet (15), enter after positive resin regeneration, cleaning tower regenerate, clean, enter operation again by positive resin inlet (13), the mobile negative resin is saturated gradually in operational process equally from the bottom up, from negative resin outlet (12) flow out enter negative resin regenerator column, cleaning tower and regenerate, clean after, enter operation once more by negative resin import (14), guarantee the continual renovation of positive and negative resin thus, carry out continuously thereby guarantee to exchange.
In order to prevent to be provided with some water distribution baffle plates (6) in the tower body (1),, and can not go here and there on a large scale so that resin moves in a certain section relatively because of the inhomogeneous resin layer of upsetting of local current.
The utility model is simple and reasonable for structure, the design of its positive and negative resin layer cross arrangement, make the existing independent separately resin layer of positive and negative resin formation in the tower body, one mixing zone is arranged again, so both having helped the desalination permutoid reaction carries out thoroughly, and can reduce the tower body height, improve space availability ratio in the tower, guarantee that again the positive and negative resin enters regeneration and can not mix during the stage simultaneously.With the utility model is that the center is equipped with regeneration, cleaning tower can be formed the thermopnore demineralization plant, it can realize the continuous circular flow of exchange, regeneration, cleaning of positive and negative resin, thereby the ion-exchange demineralization system of realization water carries out for a long time continuously, and the one-level desalination that is widely applicable for industry process waters such as low pressure boiler and metallurgy, weaving, papermaking, chemical industry, food is handled.
Fig. 1 is the utility model structural representation.
Embodiment: this is for example shown in Figure 1, tower body (1) upper end is the catchment area, de-mineralized water water outlet (11) is distinguished derivation thus, raw water inlet (16) is arranged on tower body (1) bottom, former water enters after water-distributing device (17) evenly enters at the bottom of the tower, sun resin outlet (15), negative resin import (14), sun resin inlet (13), negative resin outlet (12) sets gradually from bottom to top, its middle-jiao yang, function of the spleen and stomach resin outlet (15) is arranged on the tower body bottom, sun resin outlet (12) is in tower body (straight figure) upper end, for pipeline easy for installation, also should stagger in position, each mouthful left and right sides, its middle-jiao yang, function of the spleen and stomach resin inlet (13) requires to stagger bigger with negative resin import (14).Distance between sun resin inlet (13) and the negative resin import (14) has determined the height of mixing region substantially, should select suitably, and generally its distance is 1/4～1/2 of tower body (straight figure) length.This example is provided with two water distribution baffle plates (6), and one is arranged on positive resin inlet (13) top, and one is arranged on negative resin import (14) below, substantially be the mixing zone therebetween, it can make liter waterborne even, also makes the resin layering comparatively clear, has guaranteed to flow out the purity of resin.
