Description
Technical field
The present invention relates to waste material brickmaking field, related in particular to energy-saving sintering heat-reserving brick.
Background technology
In the paper industry field; The annual a large amount of mud that produce in paper mill bring serious pollution problem to environment; Along with the day by day raising of country to the industry environmental protection requirement, mud how to dispose the annual enormous amount that produces of paper-making industry has more and more become the focus that people pay close attention to.If adopt the burning disposal not only can atmosphere pollution, and it be huge to consume energy; If adopt and fill up processing, then can pollute to underground water resources.Therefore, how to handle paper mill mud and become the environmental issue that the paper industry field presses for solution at present.
Cinder is a kind of of industrial solid wastes, and the coal-fired waste residue of discharging of fuel-burning power plant, industry and civil boiler and other equipment is claimed slag again.The chemical ingredients of cinder is silicon-dioxide 40～50%, aluminium sesquioxide 30～35%, iron protoxide 34～20%, quicklime 1～5% and small amount of magnesium, sulphur, carbon etc.Cinder is thrown aside accumulation, and not only land occupation is emitted the sulfurous gas atmosphere pollution, the harm environment, in addition can spontaneous combustion on fire.People just began to utilize cinder to make trinity mixture fill in 18th century, as material of construction.Since 20th century, countries in the world are all in the comprehensive utilization of carrying out cinder, and state's cinders such as Japan, Denmark all obtain utilizing.The main application of cinder is a manufacture building material.Such as, cinder can be used as roof heat insulation or indoor foundation material, also can make road-making material, sand blasting-used sand etc.Cinder if can rationally use the brickmaking field, then constantly can turn waste into wealth, save resource as a kind of recyclable resource of utilizing, and has well protected ecotope.
Riverway sludge is the natural settling that river flow to form, and has a large capacity and a wide range, if do not renovate and utilize; It can deposit and raise the riverbed, forces the river overflow, if run into flood flood season; Dangerous situation can occur, seriously jeopardize the river course people across the Straits masses' the security of the lives and property.Country all will spend great amount of manpower and material resources and financial resources in the alluvial of improvement channel deposits last every year.If can make good use of mud, not only can turn harm into good, turn waste into wealth, save resource, improve environment, and help river regulation.Dig out riverbed behind the mud simultaneously and how long can not become silted up flatly again, visible river silt is inexhaustible, nexhaustible comparatively ideal raw materials for production, utilizes properly, will be the very high precious resources of a kind of potential value.Such as, a large amount of riverway sludges is used for material of construction, can utilize the waste material that flows to economize the land resource well, reduce the harm of mud to lower reaches of river.
In waste material brickmaking field, people have invented certain methods and have utilized the waste-material-preparing vitrified brick.Such as; Application number is 200810013838.9, the applying date be January 16, notification number in 2008 be CN101215147, open day be on July 9th, 2008, application people for the Chinese invention patent application of Shandong Zhongli New Building Materials Co., Ltd. discloses a kind of high blending quantity sewage treatment sludge clinker brick and preparation technology thereof, belong to and utilize the making brick from sludge technical field.Raw material is the WWT throw out, Yellow river silt, a kind of or combination of coal gangue, industrial slags.The preparation method comprises raw materials mix, pulverizing, water transfer homogenizing, base, oven dry, sintering.This invention utilizes raw materials such as Yellow river silt and industrial slags to prepare vitrified brick, though played to a certain extent turn waste into wealth, aim of saving, existing waste material is not made full use of, have further improved necessity of optimization.
Summary of the invention
The proportion and the density of the waste material that the present invention is directed in the prior art to be utilized are bigger; Needing under the prerequisite of environmental protection treatment, production cost is higher, the shortcoming that existing waste material can not be fully utilized; Provide a kind of through increasing the waste material kind; Change proportioning of waste, production cost is lower, under the prerequisite of environmental protection, can make full use of the energy-saving sintering heat-reserving brick of waste material.
