Abstract

The invention relates to a calcining-free brick prepared from silt after oil extraction for the second time, which belongs to the technical category of the subsequent problem of the regeneration of energy resources. The method for preparing the calcining-free brick comprises the following steps: utilizing the active component of a finishing agent which remains in silt with oil extraction for the second time, adding sand, mud, fine stone, cement, lime, or calcium carbide mud, fly ash and a curing agent, pressing after stirring, and molding. After being cured, the compressive strength of the calcining-free brick is averagely 12.5Mpa, the freezing resistance strength of the calcining-free brick is averagely 9.1Mpa, and the calcining-free brick conforms to the national standard and can be usedfor paving a road and building a wall. The calcining-free brick has no pollution, firmness and endurance, can save a raw material for calcining the brick and even can utilize the silt with oil extraction for the second time extremely, and the procedures of the technology are more than ten less than the procedures of a common calcining brick. The calcining-free brick has low cost and simple process and is a better construction material.

Description

With silt after oil extraction for second time make non-burning brick

Technical field

The present invention relates to the utilization of waste material after the utilization of waste material, be a kind of with silt after oil extraction for second time make non-burning brick, be to allow utilization of waste material a kind of brick to the utmost point, it loses problem technology category after belonging to energy regeneration.

Background technology

The non-burning brick background technology that the present invention makes with silt after oil extraction for second time is like this: well-known, the greasy dirt in oil field pollutes, and is a problem extremely to be solved.Now, have the target of many technological development all to fix on this problem, if any Oilfield using fill out the method handling oil mud of natural evaporation concentration, periodic cleaning, or use simple equipment, allow greasy dirt separate, carry wet goods then for the second time.Yet these methods are all immature, as the former, it cannot solve greasy dirt at all and finally handle, and the latter, though oil extraction for second has certain positive effect, but still exist practical problems, because the greasy dirt that secondary is carried needs to add the treatment agent of doses, so just has the activeconstituents of many treatment agents to be retained in the earth after carrying oil, this earth is quite long by the natural degradation time, handy ten years its time was meter, and as not handled once more, it still can cause the pollution of environment.

Summary of the invention

The present invention with silt after oil extraction for second time make non-burning brick, be one of best-of-breed technology scheme that proposes at the problems referred to above.Leaving in the soil behind the greasy dirt oil extraction for second, owing to carry the treatment agent that will add doses in the oily process, contain some activeconstituentss in these treatment agents, the avidity of it and band oil sediment is better than avidity between oil and silt, this avidity is a kind of combination of unstable state, it is breaking oil and mud bonded while, promptly change water body over to again with oil and mud desorb, produce chain reaction, constantly break combining of other oil molecule and mud, thereby when making greasy dirt be proposed oil treatment once more, again the silt that is left behind the oil extraction for second has been changed into and can be used as non-burning brick base-material, this base-material is adjusted to the husky 40%-50% of maintenance, mud 20%-30%, microlith 7%, cement 15%-20%, lime or calcium carbide mud 3%-5%, flyash 10%-20%, solidifying agent 3%-5%, stir back brick machine compression moulding, sign indicating number amasss into buttress, builds with plastic cloth then, makes it to solidify.Non-burning brick after the compression moulding, ultimate compression strength average out to 12.5Mpa, freeze proof intensity average out to 9.1Mpa conforms with national standard, can pave the way and build a wall.It not only can exhaustively utilize the silt that is left behind the oil extraction for second, and its production method will simplify ten multiple working procedures than ordinary fired brick, and consume fuel is not with low cost, and firm permanent.

Specific embodiments

The present invention with silt after oil extraction for second time make non-burning brick, be after a kind of repressed moulding by self solidified brick, must yard amass into buttress after its compression moulding, build with plastic cloth in the outside then, treat the solidifying agent post-hardening that plays one's part to the full.Therefore, need again water of spray on the brick next day after sign indicating number amasss into buttress, to make it more fully hard.

Claims

1, a kind of with silt after oil extraction for second time make non-burning brick, it is characterized in that through the batching stirring pressing and moulding: batching is made up of husky 40%-50%, mud 20%-30%, microlith 7%, cement 15%-20%, lime or calcium carbide mud 3%-5%, flyash 10%-20%, solidifying agent 3%-5%.

2, according to one kind of claim 1 with silt after oil extraction for second time make non-burning brick, it must have brick press compression moulding, it is characterized in that: the brick of moulding must amass into buttress by sign indicating number, builds with plastic cloth in the outside then, solidifies waiting.
