Abstract
A brickmaking method utilizing heat energy of sludge from a municipal sewage treatment plant. The method utilizes sludge from a municipal sewage treatment plant, fly ash and shale as raw materials to roast bricks according to a certain production technology. The method effectively utilizes heat energy in sludge to solve a problem of sludge disposal and realize resource application of sludge. Besides, a high water content in sludge is utilized to reduce water consumption in a brickmaking process, so as to save water resource. A shale brick produced by the method is environmental-friendly and compression- resistant, and is a novel material for load bearing wall.
Description
Technical field
Patent of the present invention relates to a kind of method of utilizing the brickmaking of sludge from wastewater treatment plant heat energy.
Background technology
At present, brick-making method commonly used is at first to use shale, flyash to make adobe, generates shale brick by high temperature sintering, has substituted the method for using clay-brickmaking the earliest.The production of shale brick does not re-use clay, has significantly reduced the destruction to land resources.This method will consume a large amount of flyash, and along with the continuous development of industrial equipments, the calorific value of flyash is more and more lower, is not enough to the calorific value that provides enough under a stable condition.In addition, shale also is a kind of resource, can not indefinitely use.
Summary of the invention
We have carried out a large amount of repetition tests after finding that sludge from wastewater treatment plant itself contains heat, at last by test, doing during the brick raw material mixes than process, add a certain proportion of mud, brick can be fired success fully, and product environmental protection, resistance to compression meet national walling standard.Admixture the adobe of mud, the objectionable constituent of mud have been removed by the kiln high temperature of thousands of degree, need in the process of production adobe simultaneously with a large amount of water, utilize the high-moisture percentage of mud, also saved water resources greatly,, thoroughly solved a great problem of sludge disposal by our successful test, and turn waste into wealth and really realized refuse reclamation, also saved resource simultaneously.The beneficial effect of patent of the present invention is, realized the recycling of mud, saved shale resource and water resources.
Embodiment
Utilize mud to become adobe, after firing by kiln 1000 degree pyritous then, become qualified new wall material standard square with the certain flyash and the contrast stirring and processing of shale.
Claims (3)
1. a method of utilizing mud to produce brick is characterized in that making the brick embryo by the proportioning of adjusting mud, flyash and shale, utilizes the organic matter of mud self to provide heat energy as thermal source, produces qualified new wall material standard square.
2. mud according to claim 1 is produced the method for brick, also can utilize the high-moisture of mud to reach the purpose of saving water resources in mixing process.
3. mud according to claim 1 is produced the method for brick, has solved a great problem of sludge disposal, and the real refuse reclamation of turning waste into wealth, and has also saved water resources simultaneously.
