Abstract
The invention discloses a device for improving the quality of dilute sulfuric acid in a desulphurization system, and belongs to the technical field of desulfurization. The device comprises a shell body; the interior of the shell body is divided into two chambers of an upper chamber and a lower chamber by a pipe plate, the upper chamber is a clear dilute acid area, and the lower chamber is a liquid inlet area; the clear dilute acid area is connected with a clear dilute acid outlet; the liquid inlet area is connected with a slag discharge port, a liquid inlet, and a rinsing port; filter pipes are distributed at the circumference of the pipe plate; the liquid inlet and the rinsing port are respectively located below and above the filter pipes; the slag discharging port is located at the lower end of the shell body. A set of filer device is added before dilute sulfuric acid obtained from washing a desulfurization tower passes through a finished product acid tank; after the dilute sulfuric acid obtained from washing is treated by the device, the dilute sulfuric acid has high purity, and can be directly sold outside or used for an ammonium sulfate chemical production work section, so that certain economic value is produced while secondary pollution is avoided.
Description
Technical field
The present invention relates to technical field of desulfurization, particularly to the device improving dilute sulfuric acid quality in a kind of desulphurization system.
Background technology
Because coke oven flue gas composition is more complicated relative to other industry, wherein contain the particulate matter such as gasification tar, heavy metal, and desulphurization catalyst is again with carbon back for carrier in coke oven flue gas catalytic oxidation desulfurization technology, therefore, the dilute sulfuric acid washed by beds certainly will carry above-mentioned impurity and carbon dust secretly, the dilute sulfuric acid inferior quality resulted in, easily blackout, cannot utilize, cause secondary pollution, directly affect the popularization in coking industry flue gas desulfurization of this technique.
Summary of the invention
It is an object of the invention to overcome above the deficiencies in the prior art, it is provided that a kind of coking flue gas desulphurization system improves the device of dilute sulfuric acid quality.The present invention the technical scheme is that a kind of desulphurization system for achieving the above object improves the device of dilute sulfuric acid quality, it is characterized in that: include housing, it is divided into upper and lower two chambers by tube sheet inside it, epicoele is clear diluted acid district, and cavity of resorption is feed liquor district, and clear diluted acid district is connected to the outlet of clear diluted acid, feed liquor district is connected to slag-drip opening, inlet, rinse mouth, the circle distribution of tube sheet has chimney filter, and inlet, rinse mouth lay respectively at the lower section of chimney filter, top, and slag-drip opening is positioned at the lower end of housing.
Further, the material of described housing is glass steel or stainless steel, and diameter is 300-2500mm.
Further, described chimney filter is politef microfiltration tube, and diameter is 20-50mm.
Further, the distribution mode of described chimney filter is uniform.
Further, the material of described tube sheet is glass steel or stainless steel, and thickness is 10-25mm..
Further, the operating pressure of described device is 0-0.25Mpa, and operating temperature is 0-80 DEG C.
The dilute sulfuric acid that the present invention washs at desulfurizing tower increases by a sets filtering device before finished acid tank, the dilute sulfuric acid washed is after this device processes, purity is high, can directly take out or for changing product ammonium sulfate workshop section, it is to avoid produce certain economic worth while secondary pollution.
