Description

A kind of materials for wall and with the method for this materials processing wall body brick

Technical field

The invention belongs to materials for wall and processing technique field thereof, be specifically a kind of by paper mill sludge and printing and dyeing sludge as the materials for wall of main raw material and with the method for this materials processing wall body brick.

Background technology

In view of conventional clay is raw material with the clay, the havoc good farmland.Be lower than China of world average level for land resources per capita, protection land resources, all kinds of non-clay matter of Development and Production materials for wall, it is inevitable particularly utilizing solid waste to produce materials for wall.Make the strong point that walling unit replaces conventional clay to have the protection good farmland, economize the land resource in view of the flyash that utilizes industrial waste such as fuel-burning power plant again.So Chinese patent CN1398813A discloses the technology enlightenment of making vitrified brick of flyash and wilkinite.But because a lot of regional flyash have belonged to and a day commodity resource category in one's favour at home, raw material sources both can not get ensureing, and price is higher, and wilkinite is a kind of Mineral resources, and the vitrified brick cost that these two kinds of raw materials of applying are processed into is higher.The content of for example having introduced flyash in this technical scheme is 85～95%.Thereby, both be difficult to obtain the flyash source and supported uncontrollable again cost brickmaking manufacturer.Also in view of the mud that is produced for papermaking, dyeing waste water control, treatment process commonly used at present is to adopt sanitary landfill, burning disposal etc., the former had both taken land resources and can cause secondary pollution, the latter except once investing the height, also need consumes energy, working cost is also high, and the residue after burning also need be handled.For this reason, utilize mud and other solid waste, produce materials for wall and be no lack of report in the literature as raw material.

Chinese patent Granted publication CN1217239A has announced the method for utilizing the sludge heat energy baking light bricks, its the instruction people technical scheme be: with sludge dewatering to water content 50～60%, and make the particle of 3～9mm, dry back with 10～30% ratio sneak in the raw clay, base, air-dry, roasting.This method has positive effect to environmental protection.But this method mud handling capacity is not high, and still will consume 60～90% clay, so protection land resources is not brought gratifying positive effect.Mention in the concrete operations step about sludge dewatering: the mud of separating in belt filter press dewaters under＜100 ℃ temperature, and this needs consumes energy.

Again; Chinese patent publication number CN1299790A has disclosed the brick-making process that utilizes papermaking waste material; this method be with 10～30% paper mill sludge blending in 60～90% earth or flyash; mixed mutually with 60～90% earth again; protection does not produce significantly achievement to method to land resources; its mud incorporation also is no more than 30% (CN1217239A is similar to notification number), and this method will rely on mould and take the tool kiln-firing, thereby is difficult in actual production even can't implements.

Also; Chinese patent publication number CN1587569A has disclosed the preparation method of full internal combustion light brick; this method has been done objective appraisal to the existing defective of aforesaid CN1299790A in background technology; the paper mill sludge consumption is compared with above-mentioned document in this method; though certain increase is arranged but still below 50%; and still need consume 50～55% clay resource, not obvious to the contribution of protection land resources.And one of the key in this method mud being utilized " mummification " do not set forth, and be very difficult even can't organize production and apply.Because the first step of sludge treatment and resource utilization is exactly mummification, otherwise burns, produce building materials, even landfill all will be difficult to implement.For example: mud state of nature water ratio generally reaches 80%, as without mummification, must cause mixture moisture obviously higher, and can't shaping forming.It is not proper proposing without sterilant in this method.To the sludge disinfection germicidal treatment is conventional requirement, because contain pollutents such as bacterium and organic matter in most mud, as very fast rotten and give an offensive smell without disinfection processing meeting, surrounding environment and operator is produced new pollution.

Again, Chinese patent Granted publication CN1413939A has released production method of sludge baked brick, though this method consumes sludge quantity and still is no more than 50% but exempt from clay thereby the meaning that has more environmental protection and economize the land resource, yet, this method is recommended the shale of using and is subjected to regional restraining factors big, be suitable for being distributed with the area enforcement of shale resource, this method is not discussed a main difficult problem one sludge dewatering of mixing making brick from sludge again, therefore, in actual production, be difficult to carry out, because of this method requires comparatively harshness to the temperature increasing schedule of going into the kiln roasting, be difficult to grasp again.

And then Chinese patent publication number CN1562864A has introduced the method for making clay brick with mud, and this method is utilized the mud brickmaking of river training, lake gained, and waste resource is fully used, and has solved the outlet of mud.But the equipment input cost in comparatively loaded down with trivial details, the whole brickmaking process of the technology that this method is introduced is big, energy consumption is high, be not suitable for suitability for industrialized production.In addition, 250～600 ℃ of the maturing temperatures of mentioning in this method lack technical basis (routine techniques brickmaking sintering temperature is minimum also to be needed more than 850 ℃), can't sintering under this temperature.This method provides the method for drying sewage sludge on the conveying belt in drying room, and this is the progress than above method, but the thermal source of this drying room need consume fuel or.Both increase running cost, caused new topsoil again.

The applicant has noticed the method for the disclosed a kind of firing building material products by utilizing contaminated river bottom mud of CN1371883A, institute's recommended technology scheme is: with consumption greater than 50% river bottom mud, flyash and 0～35% combustion-supporting material, 0～10% flux material, 0～25% agglomerated material less than 45% through fully mixing and stirring, homogenizing is made blank after handling, fire after the drying, wherein after kiln temperature reaches 800 ℃, be warming up to firing temperature, after the insulation cooling, obtain finished product with 10～40 ℃ of unit time.The weak point of this technical scheme is: the one, this technical scheme is recommended be river silt particularly to the method for firing building material products by utilizing contaminated river bottom mud, similar to CN1562864A.And added various types of materials according to the characteristic of contaminated river bottom mud and the requirement of making building material made.Wherein do not address the utilization of papermaking and printing and dyeing sludge.The 2nd, river bottom mud in this method and papermaking, printing and dyeing sludge physical and chemical performance are widely different, and moulding is also different with sintering character, but the water ratio height is a denominator.But this method does not give the technology enlightenment to the mummification in early stage of the high river bottom mud of water ratio, if limiting river bottom mud in it prepares burden greater than 50% ratio, shaping forming moisture must substantially exceed routine techniques sludge blank making moulding moisture should be controlled at 18～22% requirement, can't produce at all.And,, therefore be difficult to even can't in actual production, use in full to the basic not specified (NS) of working method.The 3rd, known to embodiment one, the product of making is haydite goods but not materials for wall, so again from embodiment two as can be known, if will obtain brick product, then still need depend on clay (Instructions Page 3 4～5 is capable); The 4th, if will obtain the brick product, require with per hour 10 ℃ of intensifications, as to rise to 900 ℃ of sintering temperatures, need 90 hours, add insulation, cooling, the cycle of total burnt brick product needs 180 hours.This is meaning just, burns till at the annular kiln of same size, and its output only is 1/4～1/5 of a routine techniques, if fruit burns till in the tunnel furnace of same size, its output only is 1/8～1/10 of routine techniques, must cause the fuel consumption height that yields poorly, so there is not application value.

The applicant has been also noted that Chinese patent publication number CN1408675A has introduced the method for utilizing regenerated papermaking mud to prepare vitrified brick; this method has been done objective appraisal to the existing defective of aforesaid CN1299790A in background technology; and environment protection there is certain active effect; one of but obvious have a following shortcoming,, with regard to vitrified brick composition and proportioning thereof; paper mill sludge is got 10～25 weight parts; it is little of part to show genus, and clay is 70～85% weight parts, belongs to greatly than part.So it is both seriously polluted to digesting, the achievement of the mud that intractability is big is not appeared suddenly, big unfavorable because of the clay consumption again to conservation of resources; Two raw materials in a large amount of clays that use, and ignored the use of mud, if can mud and mud is shared, use and exempt to use clay, then can embody the effect of double gain, this also is the shortcoming of this patented technology scheme, and this may be that this patent main purpose only provides and can partly utilize mud to produce the method for vitrified brick, certainly selected technology the clay of easy enforcement as main raw material.Three, with regard to the preparation method of its introduction, sterilant adopts clorox, because input amount is 0.5～1% of a mud weight, has increased disinfection cost, transfers on the brick product because the cost of bigization will inevitably be pass on, and is difficult to make the brickmaking industry to be accepted; Four, method recommended the drying of mud is adopted air drying, this is a very general indignant thought, and concrete method is not provided, and actual production is lacked directive function; Five, mentioned that at Instructions Page 3 the 5th row the mud consumption too much can make vitrified brick density excessive (ventilation property is poor), yet this instruction is opposite with reality exactly; Six, mention with 600～700 ℃ sintering temperature in this method sintering carried out in adobe, be to lack technical basis equally.
