Baked brick of riverslakes sludge and municipal sludge and production method thereof

Abstract

The invention discloses baked bricks of riverslakes sludge and municipal sludge and a production method thereof. The baked brick comprises a brick body and a cavity, and the brick body is prepared bythe following raw materials in weight percent: 40-70% of riverslakes sludge, 10-35% of municipal sludge and 13-30% of internal fuel. The production method comprises the following steps of collecting raw materials, batching, blending internal fuel, extruding, molding, drying, roasting and obtaining the products. The baked bricks in the invention have the advantages of energy conservation, heat preservation, superior performance and low cost, and can be widely used in wall body construction in building industry. The production method in the invention has advanced processing steps, economy, reasonability, high cost-performance ratio, and especially low energy consumption of the manufacturing process, thus conforming to the national requirements of environment protection and energy conservation and enabling riverslakes sludge to be in full resource utilization.

Description

technical field [0001] The invention relates to a brick and a production method thereof, in particular to a sintered brick made of river, lake and urban sludge and a production method thereof. Background technique [0002] How to deal with the silt in rivers and lakes and urban sludge has been an environmental issue that has plagued many countries. The silt in rivers and lakes has not been fully and effectively utilized, especially resource utilization. The main reason is that on the one hand, the sludge treatment The scale is still small, and the pressure of river and lake sludge treatment is not great. On the other hand, the treatment technology, especially the resource utilization technology, is not up to standard. For example, the technology of making bricks from river and lake sludge has been studied before, but due to technical and production method reasons, Cause excessive energy consumption in the sludge dehydration process, and the cost of the bricks produced is too...

[0002] How to deal with the silt in rivers and lakes and urban sludge is an environmental issue that has plagued many countries. The silt in rivers and lakes has not been fully and effectively used, especially The main reason is that on the one hand, the scale of sludge treatment is still small, and the pressure of sludge treatment in rivers and lakes is not great; There have been researches before, but due to technical and production method reasons, the sludge dehydration process consumes too much energy and the cost of the bricks produced is too high, so it has not been popularized and applied.
