Abstract

The present invention provides a single-table front-mounted ion-exchange deironing and mixed bed dual-purpose equipment. By using pipeline and utilizing the change-over of opening valve and closing valve, the tank body of pre-filter can be converted into the tank body of the mixed bed so as to raise its working efficiency. Said invented equipment possesses pre-hydrogen function, and can save a group of pre-hydrogen equipment, and is safe and reliable, and convenient for system change-over. Besides, it possesses a condensate desalinization function with 100% total treatment quantity, so that it can save a group of desalinization equipment, and can overcome the contamination from a large quantity of iron to mixed-bed resin when starting equipment.

Description

A preposition ion exchange iron-removing of separate unit and a mixed bed double-duty plant

The present invention relates to condensate-scavenging installation.

The main purpose that condensed water is handled is iron and the salt that removes in the condensed water, and the deironing amount when ratio runs well during the main frame unit starting is big, and the desalination amount was big when ratio ran well when having an accident.H-ion exchanger is set is mainly deironing, mixed bed is mainly desalination, respectively brings into play major function when both connect.Be the common deironing desalting system that fore filter is arranged shown in Fig. 1, fore filter A arranged shown in the figure, mix bed B that this running effect is better, but invests excessive.

Fig. 2 a-2c is depicted as the mixed sheet level equipment of setting up of common no preposition strainer and finishes two kinds of functions, reduced investment, but the cycle is short, and resin loss is big.It is standby that wherein Fig. 2 a and Fig. 2 b have operation, and these two kinds of systems at home and abroad are in the great majority, and Fig. 2 c does not have spinning reserve investment and economizes, but in service many technological deficiencies are arranged.As previously mentioned, at present both at home and abroad common system or preposition hydrogen ion exchange is arranged or the simple bed that mixes is handled does not have dual-purpose system.

It is excessive to the objective of the invention is to overcome the prior art deironing desalting system investment that fore filter is arranged as shown in Figure 1, and the no preposition filtering investment shown in Fig. 2 c economizes but the problem that has many technological deficiencies in service, and good iron removal effect when providing a kind of Fig. 1 of getting both system to start obtains Fig. 2 a, Fig. 2 b simultaneously and has the standby uninterruptible deironing separate unit preposition ion exchange iron-removing dual-purpose with mixing bed and mix a bed double-duty plant.

Concrete technical scheme of the present invention is as follows: a preposition ion exchange iron-removing of a kind of separate unit and a mixed bed double-duty plant, comprise tank body (1), tank body (2), connect pipeline and each valve, tank body (1) top has the admission port (a) and the water dispensing apparatus (3) of condensed water, the middle part has female pipe (8) and arm (9), and Long handed water cap (5) is housed, one arc-shaped partition is arranged at the bottom, and many through holes are arranged on this arc-shaped partition, water cap (6) all is housed on each through hole, the arc-shaped partition bottom also has row's fat mouth (c), and tank body (1) bottom has condensed water gangway (10).Can switch to become by the opening and closing of valve on the pipeline as the tank body (1) of fore filter (A) and mix bed (B); As the tank body (1) of fore filter (A) and tank body (2) series operation that mixes bed (B), as the tank body (1) that mixes bed (B) then with tank body (2) parallel running that mixes bed (B).Tank body (1) is as follows as the conversion process of fore filter (A) or the mixed bed of conduct (B): when I, main frame unit starting, in the tank body (1) as fore filter (A) Zeo-karb (7) is housed, the fat face height of Zeo-karb (7) is (h ₂+ h ₃); Water of condensation enters in the tank body (1) from the vertical untreated condensed water import (a) of tank body (1) and the condensed water gangway (10) of lower end, from mother's pipe (8) outflow at middle part; When II, the normal operation of main frame unit, Zeo-karb (4) in the tank body (1) is discharged by row's fat mouth (c), and charge into anion-cation exchange resin (7) from grease inlet (d), untreated water of condensation enters in the tank body (1) from the vertical import of tank body (1) (a), flows out from the condensed water gangway (10) of lower end; Anion-cation exchange resin charges into and highly is h ₄, the medullary ray of female pipe (8) is h apart from the distance of arc-shaped partition ₅h ₅=1000～1600mm.

The preposition ion exchange iron-removing of separate unit of the present invention and mixed bed double-duty plant advantage and effect:

1, have preposition hydrogen function and save one group of preposition hydrogen storage equipment, double-duty plant is safe and reliable, system's easy switching;

2, there is condensed water to handle total amount 100% and removes salt functional, save one group of demineralization plant;

When 3, overcoming unit starting in the water a large amount of iron to the pollution of mixed-bed resin;

4, the Zeo-karb of polluted by iron is cleaned separately in the preposition hydrogen, alleviates broken positive resin and sneaks into negative resin;

5, compare with equipment with the common system of water quality effect with reaching same technical functionality, each group (is always handled water yield 800m ³/ h), expense 2,000,000～3,000,000 yuan of can reducing investment outlay.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the common deironing desalting system that pre-process is arranged

Fig. 2 a～2c is common no preposition processing mixed-bed system

Be described further below in conjunction with drawings and Examples:

Fig. 4 and Figure 5 shows that fore filter A closing and opening and to switch the situation of mixing bed B that becomes by valve on the pipeline.Pass through to connect the switching and tank body 2 series operations that mix bed B of pipeline as seen from Figure 4 as the tank body 1 of fore filter A, heavy line is the pipeline of condensed water circulation among the figure, fine line is the pipeline that turn-offs, the situation of independent deironing or deironing desalination when being unit starting shown in the figure, undressed water of condensation enters from two ends, draw by the centre, what adorned in the tank body 1 is Zeo-karb, and the switching by pipeline in Fig. 5, on the one hand the Zeo-karb in the tank body 1 is discharged by row's fat mouth C, charge into anion-cation exchange resin 4 from grease inlet d, (see Fig. 6, Fig. 7) water of condensation is flowed by the heavy line among Fig. 5, this moment, tank body 1 promptly became a mixed bed B, the operation scheme of desalination when this is normal operation.

Can be more clearly visible conversion process in the tank body 1 from Fig. 6 and Fig. 7, tank body 1 as fore filter A shown in Figure 6 is the deironing state of double fluid to ion-exchanger, tank body 1 top has the water-in a and the water dispensing apparatus 3 of water of condensation, on middle female pipe 8 Long handed water cap 5 is housed, one arc-shaped partition is arranged at tank body 1 bottom, and many through holes are arranged on this arc-shaped partition, water cap 6 all is housed on each through hole, tank body 1 inside is Zeo-karb 4, this is at the state by heavy line flow pattern shown in Figure 4, when running well, pass through to switch each valve, press the heavy line flow pattern of Fig. 5, and emit Zeo-karb 4 in the tank body 1, when charging into new anion-cation exchange resin 7, then become as shown in Figure 7 desalination with the mixed bed state of single current to ion-exchanger.Mother shown in the figure manage 8 and arm 9 at resin surface height h ₄On, water cap 5 stretches into the anion-cation exchange resin layer.The situation water cap 5 of pressing Fig. 6 is at size h ₂And h ₃At the interface.H among the figure ₅=1000～1600mm.
