Description
Technical field
The utility model belongs to anthraquinone hydrogen peroxide solution production technical field.
Background technology
The used oxidation reactor of existing market cools off with many group " U " shape water tanks or carries out heat exchange cooling in the tower without water tank, and have following defective: 1) air draught skewness, it is insufficient to cause air to contact with hydride.2) hydride is prone to cause bias current and back-mixing in oxidizing tower, has reduced the efficient of tower.3) in the gas-liquid uphill process, minute bubbles aggregate into air pocket easily, and oxidization-hydrogenation ratio is low, and oxidization-hydrogenation ratio only has about 91%.4) the hydride oxidation is incomplete, has increased the burden of back operation, causes back operation operation not steady.5) oxygen content is high in the oxidized tail gas, and generally about 6%, air utilization ratio is low.6) inhomogeneous cooling is even, and hydrogen peroxide solution decomposes easily.
Summary of the invention
The utility model purpose is to above defective a kind of raising oxidization-hydrogenation ratio to be provided, and reduces the discharging and the product cost of atmosphere pollution, and the combined type heat exchange that improves service life disperses reaction unit.
The utility model comprises housing, gas-liquid inlet tube, gas liquid outlet pipe, and said gas-liquid inlet tube is arranged on the housing lower end, and said gas liquid outlet pipe is arranged on the housing upper end; In said housing, casing is set, the upper and lower side of said casing and housing welding are provided with inlet tube and the outlet that is communicated with casing on said housing, and said inlet tube is arranged on casing one side lower part, and said outlet is arranged on casing opposite side top; In said casing, evenly arrange many bellowss, the upper/lower terminal of every bellows is communicated with the inner chamber of housing respectively, also is provided with the distribution cap in the upper end of every bellows; Gas-liquid distribution grid again in horizontally set top in the housing above said casing; Said top gas-liquid is uniformly distributed with through hole on the distribution grid again; Between distribution grid and the housing gap is set again in the top gas-liquid above the said outlet, liquid barrier is being set on the housing below this gap; Gas-liquid distribution grid again in horizontally set bottom in the housing below said casing; Said bottom gas-liquid is uniformly distributed with through hole on the distribution grid again; Between distribution grid and the housing gap is set again in the following gas-liquid below the said inlet tube, liquid barrier down is set on the housing below this gap.
The utility model utilizes redistribution technology to improve in air and the hydride course of reaction two mutually mass transfer rates in oxidation reactor, avoids bubble coalescence one-tenth than air pocket, has increased the two-phase medium contact area; Utilize redistributor that air is repeatedly distributed again, reduce the bias current and the back-mixing of two materials in the tower, improved oxidization-hydrogenation ratio, oxidization-hydrogenation ratio can reach 99%, improves column efficiency; Reduced the oxygen content in the oxidized tail gas, oxygen content is about 4% in the oxidized tail gas, has reduced air consumption, saves power, reduces exhaust emissions amount and supplies consumption, thereby has reduced the discharging and the product cost of atmosphere pollution; Reduce hydrofenating anthraquinone content in the oxidation liquid, alleviated the load of extraction and postprocessing working procedures, increased hydrogen peroxide solution output; Material is evenly cooled off, suppress the decomposition of hydrogen peroxide solution; Adopt the heat exchanger tube of bellows that automatic expansion compensation property is arranged, drawing crack when preventing that weld seam from expanding with heat and contract with cold.
