Abstract

This utility model relates to an active carbon pickling bath, belonging to chemical equipments. The device comprises a pickling bath, a circulating pump, a filter, an acid reservoir, a lye reservoir and a neutralization reservoir. The lower part of the pickling bath is funnel shaped and the upper part column shaped. A char inlet is fixed in at the bottom of the lower part, on the top wherein fixed a lower distribution pipe with a pickling liquid inlet on the right side connected with the upper distribution pipe. The device has the advantages of simple structure, convenient operation, simple maintenance and better practicability. With no blending system, the active carbon is in immobility; through circulation of the pickling fluid to accomplish pickling activation, there is no loss of active carbon.

Description

Active carbon descaling bath device

Technical field

The utility model relates to the chemical industry equipment class, and particularly a kind of active carbon descaling bath device refers to a kind of circulating no stirring active charcoal descaling bath device especially.

Background technology

As everyone knows, along with development and national economy, use the scope of active carbon more and more wider at present both at home and abroad, the general mode that adopts the pickling tank diameter, be about to treat that pickling carbon packs in the pickling tank diameter, stir a period of time after adding pickle, to reach the purpose of pickling, this owing to adopt alr mode to carry out pickling, cause activated carbon granule broken in a large number, thereby reduce its average grain diameter, increase the amount of screenings, and then the loss that increases active carbon, therefore be badly in need of a kind ofly can reaching the active carbon pickler that pickling effect can reduce the active carbon loss again, to change domestic present situation at present in this industry.

The utility model content

The purpose of this utility model is to provide a kind of active carbon descaling bath device, problems such as the loss that has solved the active carbon that present active carbon pickling processes exists is big, pickling effect difference.

The technical solution of the utility model is: adopting does not have the endless form that stirs, by adding certain chemical agent aqueous solution regenerated carbon is handled, the impurity dissolving of adsorbing in its surface and the hole is removed, thereby the adsorption activity of active carbon is restored, and active carbon is in stationary state in processing procedure, no any wearing and tearing and whipping process, not easy damaged and loss; The technical solution of the utility model is that the active carbon for the treatment of pickling is sent in the descaling bath through conveyer belt, quantitative pickle is entered in the descaling bath through acid storage tank, carried out cycle pickling 1～2 hour by pump, the alkali lye that adding prepares from lye tank (vat) is to descaling bath again, carry out the alkali cleaning circulation by pump, carry out the water wash cycles then; The pickling recycling waste water enters in the neutralization chamber with discharging after the alkali lye neutralisation treatment:

Concrete structure of the present utility model is made of descaling bath, circulating pump, filter, acid storage tank, lye tank (vat), neutralization chamber, wherein the lower groove of descaling bath is funnel-form, it is cylindric that upper groove body is, bottom at lower groove is provided with carbon outlet port, be provided with down distributor pipe in carbon outlet port upper end and be fixed on the lower groove, be provided with the pickle inlet tube and be connected with following distributor pipe at distributor pipe left end down with bracing frame; The lower groove funnel mouth is connected with the upper groove body cylinder, is provided with distributor pipe on upper groove body cylinder top and with hanger and the solid welding of upper groove body wall, the left end of last distributor pipe is provided with the pickle outlet and is connected with last distributor pipe;

When work, the active carbon for the treatment of pickling is sent in the descaling bath through conveyer belt, quantitative pickle enters the pickle inlet tube through acid storage tank, carry out 1～2 hour cycle pickling by pump, in the pickling cyclic process, pickle enters the descaling bath lower groove from following distributor pipe, after the distribution current-sharing, move up, the active carbon of evenly flowing through, the impurity dissolving and the process filter that adsorb in its surface and the hole are removed, flow out descaling bath through last distributor pipe again, carry out the water wash cycles then, the water wash cycles is near neutral to cleaning fluid pH value; The NaoH alkali lye that adding prepares from lye tank (vat) carries out alkali cleaning circulation 1 hour by pump to descaling bath again, keeps alkali wash water pH＞9, carries out the water wash cycles then to the nearly neutrality of cleaning fluid pH value; The pickling recycling waste water enters in the neutralization chamber, with discharging after the alkali lye neutralisation treatment.

Advantage of the present utility model is: simple in structure, easy to operate; No stirring system, active carbon is in stationary state, finishes acid-wash activation by circulating of pickle, and active carbon is lossless, and device is safeguarded simple, and is practical.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a workflow schematic diagram of the present utility model.

The specific embodiment:

Shown in accompanying drawing 1 and accompanying drawing 2, the utility model is made of descaling bath, circulating pump, filter, acid storage tank, lye tank (vat), neutralization chamber, wherein the lower groove 2 of descaling bath is funnel-form, upper groove body 3 is cylindric, be provided with carbon outlet port 1 in the bottom of lower groove 2, be provided with down distributor pipe 21 in carbon outlet port 1 upper end and be fixed on the lower groove, be provided with pickle inlet tube 22 and be connected with following distributor pipe 21 at distributor pipe 21 left ends down with bracing frame 23; Lower groove 2 funnel mouths are connected with upper groove body 3 cylinders, are provided with distributor pipe 31 on upper groove body 3 cylinder tops and with hanger 33 and the solid welding mutually of upper groove body wall, the left end of last distributor pipe 31 is provided with pickle outlet 32 and is connected with last distributor pipe 31;

When work, the active carbon for the treatment of pickling is sent in the descaling bath by conveyer belt, quantitative pickle enters pickle inlet tube 22 through acid storage tank, carry out 1～2 hour cycle pickling by pump, in the pickling cyclic process, pickle pickle inlet tube 22 flows into distribution house keeper 21 down, warp distributor pipe 21 down enters descaling bath lower groove 2, after the distribution current-sharing, move up, the active carbon of evenly flowing through is removed with the impurity dissolving of adsorbing in its surface and the hole and through filter, flows out descaling baths through last distributor pipe 31 and pickle outlet 32 again, carry out the water wash cycles then, the water wash cycles is near neutral to cleaning fluid pH value; The NaoH alkali lye that adding prepares from lye tank (vat) carries out alkali cleaning circulation 1 hour by pump to descaling bath again, keeps alkali wash water pH＞9, carries out the water wash cycles then to the nearly neutrality of cleaning fluid pH value; The pickling recycling waste water enters in the neutralization chamber, with discharging after the alkali lye neutralisation treatment.
