Abstract
The invention discloses a leakage control method for an acid tank. The method is characterized by comprising the following steps of: welding with an acid-proof material polypropylene (PPH) according to the actual size of the acid tank to form a lining; putting the lining along the inner wall of the acid tank; fixing the upper part of the lining and the edge of the tank wall by using stainless steel expansion bolts; and reserving hoisting rings on the edge of the lining. The method can be used for local repair under the condition that the production is not affected; and the corrosion of the acid tank can be effectively prevented, and environment-friendly loss caused by acid leakage accidents is avoided.
Description
Technical field:
The present invention is used for the leakproof of spent acid pond, is specifically related to a kind of sour pond anti-leaking method.
Background technology:
Acid pond leakproof work is emphasis of neutralization station, in case reveal, will influence user's ordinary production, and then the environmental protection accident takes place; And traditional leak-proof measure one side complex process, one side is owing to user's acid discharge instability, and sour can not keep constant, and anticorrosion part will come out when hanging down for sour, and winter temperature hangs down easy generation bursting by freezing phenomenon; If local leakage takes place simultaneously, need on the basis of the face of damage, handle even all handle by extend range, also to cause the user to stop production in this case.
The active working district of steel pipe spent acid neutralizing treatment is mainly utilized lime, adds a certain proportion of flocculation agent and neutralizes, and adjusts PH at last and effluxes to neutral (6--9).Spent acid gets into the spent acid pond by the user through pipeline earlier, and rotproofing must be carried out in the spent acid pond.Present spent acid pond anti-corrosion method: the thick MFE-2 Vinylite of 0.2mm brush coating cover-120-12 woven dacron one deck, brush ring epoxy resins-116C terylene lattice cloth one deck, the anticorrosion thick HDPE liner plate of 2.5mm that adds of brush ring epoxy resins or glass reinforced plastic.But because sour pond in the open, winter temperature is low, causes preservative coat to damage easily after acid position descends and sour accident takes place to leak.
Summary of the invention:
For fear of the spent acid pond leakage accident takes place, even leak source is arranged, also can locally repair, can guarantee user's ordinary production and the environmental protection accident does not take place, the present invention proposes a kind of sour pond anti-leaking method.
Technical scheme of the present invention:
Use acid resisting material PPH, according to sour pond physical size, liner is made in welding, and inwall is put into liner along sour pond, fixes with the stainless steel expansion bolt on liner top and pool wall edge, and interior mat is reserved suspension ring, is convenient to dismounting.
The present invention can carry out the part and repair under the situation that does not influence production; Can effectively prevent the corrosion of sour pond, and then stop to take place to leak sour accident, cause the environmental protection loss.
Embodiment:
Embodiment: with acid-proof material PPH blanking, flange length (identical with pool wall thickness) is reserved on top, welds with plastic welding rod according to sour pool size, makes it become a cloth bag shape device, for the ease of dismounting, makees the suspension ring of proper amt in top edge; The stainless steel round steel of fixed diameter 16mm around in outer, sour pond is reserved the long reservation section of L=50nn; Suspension ring are hung on the reservation section, really form a pocketed.
Claims (1)
1. a sour pond anti-leaking method is characterized in that using acid resisting material PPH, and according to sour pond physical size, liner is made in welding, and inwall is put into liner along sour pond, fixes with the stainless steel expansion bolt on liner top and pool wall edge, and interior mat leaves suspension ring.
