Method for preparing ceramsite by using sludge incineration slag
The invention belongs to preparation of ceramsite from sludge, and particularly relates to a method for preparing ceramsite from sludge incineration slag, and the method specifically comprises the following steps: step 1, preparing water-containing sludge, slag, clay, fly ash, ferric oxide and zeolite, and drying to constant weight; crushing and sieving to obtain sludge powder, slag powder, clay powder, fly ash powder, ferric oxide powder and zeolite powder; 2, 50-60 parts of the sludge powder, 60-75 parts of the slag powder, 80-100 parts of the clay powder, 20-25 parts of the fly ash powder, 10-20 parts of the ferric oxide powder and 10-20 parts of the zeolite powder are weighed respectively, water is added for mixing till the mixture is wet, extrusion forming is conducted, then drying and calcining are conducted, and the ceramsite is obtained. According to the method for preparing the ceramsite by using the sludge incineration slag, the zeolite is placed in the raw materials, so that the zeolite and the clay interact with each other and cooperate with the clay to fluxing the raw materials such as the sludge, and the proportion of the ceramsite prepared from the sludge is conveniently improved.
本发明属于污泥制作陶粒，特别是涉及一种利用污泥焚烧炉渣制作陶粒的方法，具体方法包括以下步骤：步骤一，准备含水污泥、炉渣、黏土、粉煤灰、氧化铁以及沸石，烘干至恒重，打碎过筛得污泥粉料、炉渣粉料、黏土粉料、粉煤灰粉料、氧化铁粉料、沸石粉料；步骤二，分别称取污泥粉料50‑60份、炉渣粉料60‑75份、黏土粉料80‑100份、粉煤灰粉料20‑25份、氧化铁粉料10‑20份、沸石粉料10‑20份，加水混合至潮湿状，挤压成型，然后进行烘干煅烧，即得到陶粒。本发明一种利用污泥焚烧炉渣制作陶粒的方法，通过将原料中放置沸石，能够使沸石与黏土相互作用，协同黏土一起对污泥等原料助熔，从而便于提高污泥制作陶粒时的配比。
