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 [0001] The patent of the present invention relates to a method for making bricks by using the thermal energy of sludge in urban sewage treatment plants. Background technique [0002] At present, the commonly used brick making method is to first use shale and fly ash to make bricks, and then sinter them at high temperature to form shale bricks, replacing the earliest method of using clay to make bricks. The production of shale bricks no longer uses clay, which greatly reduces the damage to land resources. This method consumes a large amount of fly ash. With the continuous development of industrial equipment, the calorific value of fly ash is getting lower and lower, which is not enough to provide sufficient calorific value under certain circumstances. In addition, shale is also a resource that cannot be used indefinitely. Contents of the invention [0003] After we discovered that the sludge from the urban sewage treatment plant itself contains heat, we co...
