Abstract
The separation device of activated carbon and a pickling solution in the preparation of activated carbon from sludge, disclosed by the invention, comprises a main body device. The main body device comprises a support tray, a lifting ring is arranged at the edge of the support tray, a liquid drainage pipe is arranged in the center of the support tray, two fixed columns are connected to two sides of the liquid drainage pipe, the lower ends of the fixed columns are connected with the support tray, the upper ends of the liquid drainage pipe are in socket joint with one end of a pickling solution pipe, two connecting pipes are in socket joint with the other end of the pickling solution pipe respectively, the two connecting pipes are communicated with a pickling solution receiving container and a buffer triangular flask respectively, and the buffer triangular flask is connected with a mini negative pressure pump. The invention further discloses a method for separating activated carbon and a pickling solution using the separation device mentioned above, which comprises pouring activated carbon particles prepared from sludge together with the pickling solution into the separation device for separation, so as to finally obtain impurity-free activated carbon. During the process of preparing activated carbon from sludge, the separation device and the separation method disclosed in the invention can separate the activated carbon pellets from the pickling supernatant to remove impurities from activated carbon.
Description
technical field [0001] The invention belongs to the technical field of solid-liquid separation equipment, and relates to a separation device for activated carbon and pickling solution in activated carbon prepared from sludge, and also relates to a method for separating activated carbon and pickling solution by using the separation device. Background technique [0002] Municipal sludge is a by-product of the sewage treatment process of urban sewage treatment plants. It is an extremely complex heterogeneous body composed of organic substances, microbial cells, inorganic particles, etc., which contains a large number of various organic substances, pathogenic microorganisms, heavy metals and About 80% of the water, if not handled properly, can easily cause secondary pollution to the environment. [0003] At present, the problems related to sludge treatment in our country are very prominent. Water plants generally strip sewage and sludge, and a large amount of sludge is directly...
