Description

TECHNICAL FIELD

[0001] The utility model relates to pickling waste acid purification technical field, concretely is a kind of purification and recycling device for pickling waste acid. BACKGROUND

[0002] With the development of optical fiber communication, microelectronics, solar energy and other industries, high-purity quartz sand as an important raw material, its importance is increasingly prominent, impurity elements in quartz sand can significantly affect the performance of quartz products, among them, transition metals such as iron can affect the light transmittance and electrical conductivity of quartz products; high content of alkali metal impurities such as potassium and sodium can reduce the high-temperature resistance of quartz products, and further affect their thermal stability and optical properties. To obtain high-quality quartz sand, it needs to be purified.

[0003] Quartz sand pickling purification mainly uses acid to dissolve and separate impurities in quartz sand, so as to achieve the purpose of purification. Although the removal rate of impurities in pickled quartz sand is higher, improper treatment of waste water after removal can cause serious impact on the environment and soil, and the cost of pickling is high. Therefore, it is necessary to purify and recycle pickling waste acid, improve the utilization rate of waste acid and reduce the cost of pickling.

[0004] Now, through the waste acid purification filter, the inclined plate flocculation sedimentation and the new polyester material adsorption filtration technology are adopted. The waste acid is discharged from the quartz stone pickling section discharge pipeline into the filter from bottom to top through the inclined plate sedimentation. Most of the suspended solids are deposited into the sludge hopper and discharged regularly. The finer particles are intercepted in the upper new polyester material adsorption layer with liquid floating, and the clear liquid flows out from the overflow port.

[0005] Although this method can filter waste acid, the water inlet area of the filter is large, and the water distribution system cannot ensure uniform distribution of water flow, which can cause the water flow to be too large and reduce the sedimentation effect. At the same time, large particle suspensions may damage the inclined plate inside the filter, reducing the filtration effect.

[0006] Therefore, the present application is proposed. UTILITY MODEL CONTENTS
