Description
Technical Field
The invention belongs to the technical field of hazardous waste treatment, and relates to a barreled viscous colloidal hazardous waste treatment and recovery system device.
Background
Organic matters such as saccharides and starch or petroleum and chemical raw materials have extremely high viscosity after industrial processing, and can be quickly agglomerated into a colloid after being discharged from a machine, so that the colloid is difficult to separate. Such conditions are prevalent in the petroleum, chemical, pharmaceutical, and leather industries. This viscous, gelatinous hazardous waste is like sludge and is therefore also called sludge.
For example, the cause of serious pollution caused by chemical synthesis pharmaceutical is that the synthesis process is long, the reaction steps are multiple, the extract in each process only accounts for very little raw material consumption, often only a few percent, and auxiliary raw materials and the like account for most of the raw material consumption, and most of the raw materials are converted into 'three wastes', so that the 'three wastes' are large in generation amount, complex in waste components and serious in pollution harm. In recent years, with the rapid development of pharmaceutical industry in China, a large amount of hazardous waste is generated. The hazardous waste has complex components, contains a large amount of refractory organic matters and toxic and harmful substances, and has large environmental risk; how to properly deal with the problem has become one of the environmental issues of great concern. Among various sludge treatments, industrial sludge with high heavy metal content and pharmaceutical factory sludge are difficult to treat. The main components of the waste water generated in different stages of a pharmaceutical factory are different, and the hazardous waste generated by producing different medicines is also different, so that the components of the finally formed hazardous waste are different and are not easy to control, and the difficulty in treating the hazardous waste is high at present. Because the raw materials of the chemical synthesis pharmacy are mainly organic matters such as saccharides and starch, a plurality of processes need heating, the hazardous waste which is discharged from the machine has extremely high viscosity, can quickly self-agglomerate jelly and is difficult to separate, and the treatment difficulty of the high-viscosity jelly hazardous waste is increased. The leather industry also produces large quantities of such high viscosity colloidal hazardous waste.
At present, the high-viscosity colloidal hazardous waste is packaged in a disposable iron sheet bucket or a plastic bucket, and is generally sent to a hazardous waste treatment place for unified treatment by adopting a standard bucket with the capacity of 200L. At present, no good method exists in dangerous waste treatment places, eight sludge clusters and charging buckets can be greatly unloaded by only manually adopting simple traditional tools through cutting and impacting, and then the sludge clusters and the charging buckets are respectively smashed, so that the time and the labor are wasted, the treatment places are dirty and smelly, the working environment is severe, the treatment cost is high, and the treatment effect is not good. Therefore, the treatment of the dangerous waste is a great technical problem in the pharmaceutical industry and the sewage sludge treatment industry at present, an effective treatment technology is lacked, the incompletely treated dangerous waste can bring adverse effects to the environment and can cause social contradiction, and therefore, the treatment of the high-viscosity colloidal dangerous waste is also a serious social problem which is compelled to be solved by the attention of all levels of governments and even the whole social dispatching.
The key to the treatment of the high-viscosity colloidal hazardous waste is to separate the viscous colloidal hazardous waste from the material barrel fragments, homogenize the viscous colloidal hazardous waste, treat the viscous colloidal hazardous waste into a fluid liquid, conveniently convey the fluid liquid by a pump, and utilize the fluid liquid as a chemical raw material. Therefore, the key of the processing and recycling technology of the barreled viscous colloidal hazardous waste is to separate the viscous colloidal hazardous waste from the material barrel fragments and to homogenize the viscous colloidal hazardous waste into a flowing liquid.

A feed inlet is formed in the wall of the cleaning roller 1, and a feed inlet sealing cover 8 is arranged at the feed inlet; a shredder 9 for shredding the material barrel 45 is arranged above the cleaning roller 1, and the shredder 9 comprises a barrel inlet 10; a detachable connecting pipe 11 is arranged between the shredder 9 and the feed inlet of the cleaning roller 1; the detachable connection pipe 11 may be a telescopic connection pipe. The inner cavity of the shredder 9 is communicated with a low-pressure nitrogen source, a water spray device 12 is arranged above the inner cavity of the shredder 9, and the water inlet end of the water spray device 12 is connected with the water source. As shown in fig. 7, the mist sprayer 12 includes a top mounting plate 46, a plurality of spray heads 47 are mounted below the top mounting plate 46, and the spray angle of each spray head 47 is 105 degrees.
