Description
Technical field
The present invention relates to construction material production technical field, especially a kind of manufacturing method of composite concrete foamed board.
Background technique
The method of disposal of municipal sludge mainly has landfill, burning and several forms of land use.Wherein Sludge landfill needs
Waste pit is built in a large amount of soils, and engineering cost is very big, and there are also the environmental risks of polluted underground water；And the program of burning and processing sludge
Complexity, the drying of sludge want consuming energy, sludge incineration also to be restricted by its content of organics, somewhat expensive, and have atmosphere
Pollution problem；Land use is by after sludge dewatering, and fermented manure carries out agricultural use, but there is also heavy-metal contaminated soil,
The problem of pathogen contamination soil.
Paper mill sludge be generate during paper production and Sewage contain silt, papermaking filler, tiny fibre
The comprehensive pollutant that dimension, sewage treatment drug, micro- raw remains etc. (inorganic, organic) complex material is constituted.Big with amount,
Stench is always that paper industry enables environmentalist's thing the most nerve-racking the characteristics of with drainage flow.
Quantity of the river and lake mud in the whole nation is more considerable, due to containing heavy metal substance, Bu Nengyong in riverway sludge
In landfill or soil compost, the resource utilization space of riverway sludge is reduced, river, a large amount of of lake silt is caused to hoard,
It is serious to occupy soil space, cause environmental pollution.
Existing light-weight brick or foamed board raw materials for production mainly use tonerde, dose the progress such as flyash, gangue
It crushes, dose, stirring, base, sunning, firing, kiln discharge, the production technologies such as outward transport, there is a large amount of consuming electric powers to crush gangue,
Dust pollution air, a large amount of the problems such as consuming soil resource, be that national policy is limited.
Two above background technique only replaces part laterite with paper mill sludge, produces light-weight brick or foamed board is also used
40-60% clay consumes large amount of land resources, less than optimal technical solution.
Summary of the invention
The object of the present invention is to provide a kind of manufacturing methods of composite concrete foamed board, to solve the silt of prior art river
Mud, paper mill sludge and municipal sewage sludge are hoarded, and Exploitative potential is limited, serious land occupation space, generate secondary pollution；
The resources such as manpower, equipment, the energy, clay need to be put into；Processing cost is high；The problems such as treatment effeciency is low.
The purpose of the present invention is what is realized by using following technical scheme:
1, sludge condensation: being pumped into sludge concentration tank for sewage plant sludge and paper mill sludge respectively, the concentration bottom of pond portion blank
Bottom cleaning shoe is designed and designed, concentrates bottom of pond portion to arrange mouth in the sludge of concentrating and precipitating, extrudes pond by sludge vertical gravity in pond
Outer collection mud sump.Supernatant water is overflowed by sludge concentration tank top dovetail overflow groove.Sludge condensation pool volume is with sludge yield
Major parameter design, concentration and settlement time are 6-8 hour, and the sludge moisture content after concentration is aqueous by falling into the 98% of pond
Amount 95%.
2, sludge dewatering: the sludge moisture content come out by sludge concentration tank is very big, and generally 95%, it is very big to account for volume,
It cannot be transported to outside factory, it is necessary to which further dehydration, the technology of the present invention is to mention the sludge from sludge concentration tank to sludge dewatering
Simultaneously sludge dehydrating agent is added in machine simultaneously.Sludge dewatering equipment uses horizontal high-speed centrifugal dehydrator.By sludge concentration by moisture content
95% is reduced to 50-60%.Dewatered sludge can be accumulated, and occupied area is few, and next link can be conveyed into motor vehicle.
Sewage treatment unit can be directed to by the sewage that dewaterer is deviate to be handled.
3, raw material mixed preparing: taking municipal sludge 20% by weight percentage, paper mill sludge 30%, riverway sludge 50%,
It is uniformly mixed, into base workshop section；
4, base: cooperating raw material by above-mentioned raw materials prescription, is made porous into blank machine according to production, the demand in market
Slab；
5, it dries: the slab stacking sunning produced, in case loading of kiln produces；
6, finished product: 800-1000 DEG C of firing temperature in kiln is fired, preheating time 1.5 hours, the firing time 1 hour, is kept the temperature
Time 1.5 hours, cooled down kiln discharge, obtains foaming board finished product.
The beneficial effects of the present invention are: compared with the existing technology, the present invention both solved paper mill sludge, municipal sludge and
Riverway sludge largely hoards land occupation space, while solving the problems, such as secondary pollution environment again, saves a large amount of soil
Resource, the product lightweight burnt out, energy-saving and environmental protection, is fully achieved national standard.Building materials are also mitigated simultaneously fires enterprise's purchase
With transport Red Earth Resource a large amount of expenses, to reduce unit cost.
Specific embodiment
The sludge that municipal sewage plant generates and paper mill sludge are concentrated the present invention, dehydration, utilize sludge
In the biomass energy that contains, with a certain amount of riverway sludge mixture manufacturing lightweight, energy-saving building material.Its method and step is as follows:
1, sludge condensation: being pumped into sludge concentration tank for sewage plant sludge and paper mill sludge respectively, the concentration bottom of pond portion blank
Bottom cleaning shoe is designed and designed, concentrates bottom of pond portion to arrange mouth in the sludge of concentrating and precipitating, extrudes pond by sludge vertical gravity in pond
Outer collection mud sump.Supernatant water is overflowed by sludge concentration tank top dovetail overflow groove.Sludge condensation pool volume is with sludge yield
Major parameter design, concentration and settlement time are 6-8 hour, and the sludge moisture content after concentration is aqueous by falling into the 98% of pond
Amount 95% (paper mill sludge concentration is same as above).
2, sludge dewatering: the sludge moisture content come out by sludge concentration tank is very big, and generally 95%, it is very big to account for volume,
It cannot be transported to outside factory, it is necessary to which further dehydration, the technology of the present invention is to mention the sludge from sludge concentration tank to sludge dewatering
Simultaneously sludge dehydrating agent is added in machine simultaneously.Sludge dewatering equipment uses horizontal high-speed centrifugal dehydrator.By sludge concentration by moisture content
95% is reduced to 50-60%.Dewatered sludge can be accumulated, and occupied area is few, and next link can be conveyed into motor vehicle.
Sewage treatment unit can be directed to by the sewage that dewaterer is deviate to be handled.
3, raw material mixed preparing: taking municipal sludge 20% by weight percentage, paper mill sludge 30%, riverway sludge 50%,
It is uniformly mixed, into base workshop section.
4, base: cooperating raw material by above-mentioned raw materials prescription, is made porous into blank machine according to production, the demand in market
Slab.
5, it dries: the slab stacking sunning produced, in case loading of kiln produces.
6, finished product: 800-1000 DEG C of firing temperature in kiln is fired, preheating time 1.5 hours, the firing time 1 hour, is kept the temperature
Time 1.5 hours, cooled down kiln discharge, obtains foaming board finished product.
