The invention discloses a chemical fuming sulfuric acid synthesis reaction device, which includes a pretreatment pool (1), a regulation pool (2), a dosing pool (3), a buffer pool (4), and a clean water pool (5). The pools are connected by pipelines (6) in order. A filtering device is arranged between the buffer pool (4) and the clean water pool (5). The pipelines (6) are equipped with a lifting pump (8) and a valve (9). The synthesis reaction device provided by the invention has the advantages of simple structure, good treatment effect, low sludge water content, high clear water recovery rate, low cost, and no secondary pollution, etc.
Description
Technical field [0001] The invention belongs to the chemical industry, and relates to a synthesis reaction device, in particular to a chemical fuming sulfuric acid synthesis reaction device. Background technique [0002] my country is a country with relatively scarce papermaking resources. With the rapid development of my country's national economy, the consumption of paper products is increasing at an annual rate of 7.5%. Therefore, many paper companies in our country have turned their development goals to the recycling and reuse of waste paper. After processing the waste paper, it will produce a kind of deinking wastewater, which contains sodium hydroxide, sodium silicate, calcium hypochlorite, ink emulsion, fillers, fine fibers, papermaking additives and other harmful substances. The use of physicochemical precipitation, steam flotation and other deinking wastewater treatment devices, the structure is complex, and there are some problems in effect, such as large water content...
