Abstract
The utility model discloses a kind of chromium slag cure system, comprise storage bin, reaction tank, cleaning pond, pressure filter, solidification equipment, kaolin container, alkali-activator container and water purifying tank, described storage bin is connected with reactor inlet with cleaning pond, described reactor outlet is connected with pressure filter entrance, described pressure device solid outlet is connected with outside, liquid outlet is connected with solidification equipment entrance, described kaolin container is connected with solidification equipment entrance respectively with alkali-activated carbonatite container, and described solidification equipment liquid outlet is connected with water purifying tank.Chromium slag cure system of the present utility model effectively reduces the volume of chromium slag and avoids generation leaching institute in the follow-up landfill process of chromium ion to cause environmental pollution.
Description
Technical field
The utility model belongs to field of solid waste treatment, relates to a kind of chromic slag harmlessness treatment facility, special for relating to a kind of chromium slag cure system.
Background technology
Can produce a large amount of industrial residues at production crome metal and chromic salts process, this waste residue usually containing a certain amount of chromium, has certain harm to human body, can not directly discharge; For avoiding containing chromium industrial residue to the harm of the mankind, the mode process chromium slag that general employing is buried at present, but this mode easily causes underground water pollution, and also in common chromium slag, chromium content is lower, and during landfill, floor space is large.
Therefore, be necessary to find a kind of new method processing chromium slag, the chromium existed to overcome existing chromic wastes disposal technology easily leaches, and fills up and takes up an area excessive problem.
Summary of the invention
In view of this, the purpose of this utility model is chromium slag cure system.
For achieving the above object, the utility model provides following technical scheme:
A kind of chromium slag cure system, comprise storage bin, reaction tank, cleaning pond, pressure filter, solidification equipment, kaolin container, alkali-activator container and water purifying tank, described storage bin is connected with reactor inlet with cleaning pond, described reactor outlet is connected with pressure filter entrance, described pressure device solid outlet is connected with outside, liquid outlet is connected with solidification equipment entrance, described kaolin container is connected with solidification equipment entrance respectively with alkali-activated carbonatite container, and described solidification equipment liquid outlet is connected with water purifying tank.
Preferably, be also provided with acid bath, described acid bath is connected with reaction tank entrance.
Preferably, be also provided with breaker, described breaker entrance is connected with storage bin, exports and is connected with reaction tank.
Preferably, be also provided with waste liquid pool between described pressure filter and solidification equipment, described waste liquid pool entrance is connected with pressure filter liquid outlet, exports and is connected with solidification equipment entrance.
The beneficial effects of the utility model are:
Chromium slag cure system of the present utility model comprises chromium slag chromium ion leaching section and chromium ion absorbs cured portion, first the chromium ion in chromium slag is leached, the chromium ion absorption solidification that then will leach, effectively reduces the volume of chromium slag and avoids generation leaching institute in the follow-up landfill process of chromium ion to cause environmental pollution.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly, the utility model provides following accompanying drawing to be described:
Fig. 1 is embodiment 1 chromium slag cure system structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
embodiment 1:
As shown in Figure 1, the chromium slag cure system of the present embodiment,
A kind of chromium slag cure system, comprise storage bin, reaction tank, cleaning pond, pressure filter, solidification equipment, kaolin container, alkali-activator container and water purifying tank, described storage bin is connected with reactor inlet with cleaning pond, described reactor outlet is connected with pressure filter entrance, described pressure device solid outlet is connected with outside, liquid outlet is connected with solidification equipment entrance, described kaolin container is connected with solidification equipment entrance respectively with alkali-activated carbonatite container, and described solidification equipment liquid outlet is connected with water purifying tank.
In the present embodiment, be also provided with acid bath, described acid bath is connected with reaction tank entrance.
In the present embodiment, be also provided with breaker, described breaker entrance is connected with storage bin, exports and is connected with reaction tank.
In the present embodiment, be also provided with waste liquid pool between described pressure filter and solidification equipment, described waste liquid pool entrance is connected with pressure filter liquid outlet, exports and is connected with solidification equipment entrance.
During work, first utilize breaker that the chromium slag in storage bin is broken into fine powder, then be transported to reaction tank and simultaneously by the rinse water in cleaning pond, carry out cleaning that to stir be that chromium ion in chromium slag leaches, this also can open acid bath to think that reaction tank passes into acid solution and promotes that chromium ion leaches; Liquid after leaching enters equipment for separating liquid from solid and is separated, gained solid product is directly discharged, product liquid enters waste liquid pool and collects, then solidification equipment (this solidification equipment is equipped with zeolite) is added, chromium ion is wherein absorbed, and residue clear liquid flows into water purifying tank, then opens alkali-activated carbonatite container and kaolin container, many zeolites carry out alkali-activated carbonatite, and chromium ion is cured.
The chromium slag cure system of the present embodiment effectively reduces the volume of chromium slag and avoids producing the problems such as leaching in the follow-up landfill process of chromium ion.
What finally illustrate is, above preferred embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model by above preferred embodiment, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from the utility model claims limited range.
