With respect to prior art, the production method of sewage sludge brickmaking of the present invention has following improvement at process aspect:
The one, the novel wall material perforated brick that utilizes mud to produce, because semihard is moulded the extrusion moulding water ratio and must not be higher than 18%, therefore, the water content of mud should be controlled at 75wt-85wt%, the shale natural moisture content could satisfy the moulding requirement less than 8%.Therefore, need sewage work to provide water content to be lower than 85% mud, perhaps take nature or mechanical dehydration to become primary sport technique segment on the brick field production technique, large-scale storage space or dewatering machine become the problem of primary solution.
The 2nd, the mud of high-moisture percentage with pulverize after the shale uniform mixing very high to the requirement of equipment, mix inhomogeneously, directly influence the drying and roasting quality, product appearance and intensity are difficult to guarantee, for this reason, the present invention has carried out further invest in the transformation of real estate to existing installation, makes it satisfy the requirement of technology.
The 3rd, the burning-point of industrial silt is very low, in 350-400 ℃ of brickmaking environment.In actual production process, the calorific value of mud scatters and disappears in the temperature rise period major part, just can not provide enough net heats in the roasting stage, so not only can cause environmental pollution, also can cause the waste of raw material or cause product defective because of lacking heat for firing product.For this reason, the present invention passes through feasibility study and experiment repeatedly, further invest in the transformation of real estate has been carried out in global design to kiln, the useful length of increase equipment input and kiln, solved this technical barrier, promptly at kiln its premature combustion of gate control in the design one of intensification section, to reach effective utilization of sludge calorific value.
Fig. 2 is a thetagram of firing shale brick of the present invention, wherein dotted portion is temperature variation curve before transforming), 7-12 transforms the position again for kiln between the parking stall, can fully reduce temperature rise period mud like this because of reaching the heat losing issue that the burning-point burning causes.
The 4th, mud is fired the environmental protection feasibility of shale brick.Dioxins, be commonly called as two dislike because of.Belong to chloro thrcylic aromatic hydrocarbon compounds, the mixture of forming by more than 200 kinds of isomer, homologue etc.Malicious about 100 times than potassium cyanide of its toxicity are than about 900 times of arsenic poison.For toxicity is the strongest, the highly stable one-level carcinogenic substance that decomposes of being difficult to again.It also has genotoxicity, immunotoxicity and internal secretion toxicity.In the burning process to mud, incineration temperature is lower than 800 ℃, and the chloride rubbish incomplete combustion of plastics and so on very easily generates Dioxins.The present invention is to after the kiln transformation, and mud did not burn in early stage temperature rise period, and the later stage heats up rapidly and reaches maturing temperature (1000 ℃), and the heat that so neither can run off can not make the mud incomplete combustion again and produces Dioxins.Has good environmental protection feasibility.
