Problems solved by technology

In order to recover the metal resources in the electroplating sludge and realize the harmlessness of the sludge, smelting processing is often used to obtain the high-temperature melt for preliminary removal of impurities, and then the high-temperature melt is recovered, using sulfuric acid as the leaching agent, after acid leaching and impurity removal , extraction, crystallization, and drying to obtain products such as copper sulfate and nickel sulfate. The existing hazardous waste recycling and processing production line has low production efficiency and large energy consumption, which is not conducive to the production needs of energy saving and emission reduction.

Abstract

The invention discloses a hazardous waste recycling and processing production line, aiming to provide a hazardous waste recycling and processing production line with reasonable process layout, improved production efficiency, energy saving and emission reduction. The main points of the technical solution include: a melting device, which includes The smelting furnace installed on the right side of the storage tower, the feeding port of the smelting furnace receives the electroplating sludge from the storage tower through the conveyor belt, and makes the electroplating sludge into a melt by roasting, and the outside of the smelting furnace is provided with a cooling The furnace body is water-jacketed, and the water jacket is connected to a water tank through a pipeline, and the water tank is arranged on a mounting frame erected on the outside of the smelting furnace; and the upper end of the collection pool is provided with a slag outlet for discharging the upper layer of the melt; a slag removal device, the slag removal device is arranged on one side of the collection pool for collecting the waste slag discharged from the slag outlet; the present invention Applicable to the technical field of environmental protection production line.

Description

technical field [0001] The invention relates to the technical field of environmental protection production lines, and more specifically relates to a hazardous waste recycling and processing production line. Background technique [0002] The electroplating industry produces a large amount of electroplating sludge containing Cu, Ni and other heavy metals. Due to the different electroplating production processes, there are differences and the composition is very complex. The harm of electroplating sludge to the environment and human health has aroused great concern, and it is one of the public hazards recognized at home and abroad. Electroplating sludge contains a variety of metal components, and its quality is often higher than that of metal-rich ores. It is a cheap secondary renewable resource. In order to recover the metal resources in the electroplating sludge and realize the harmlessness of the sludge, smelting processing is often used to obtain the high-temperature melt ...
