Treatment device for environment-friendly recovery of high-silicon ZSM-5 molecular sieve synthesis mother liquor and use method thereof

Abstract

The invention discloses a treatment device for environment-friendly recovery of high-silicon ZSM-5 molecular sieve synthetic mother liquor and a use method thereof. The treatment device comprises a treatment tank body for environment-friendly recovery of the high-silicon ZSM-5 molecular sieve synthetic mother liquor, a mother liquor injection port is formed in one side of the top end of the treatment tank body and used for introduction of the high-silicon ZSM-5 molecular sieve synthetic mother liquor, a first waste liquid outlet is formed in one side of the treatment tank body, a second waste liquid outlet is formed in the side, away from the first waste liquid outlet, of the treatment tank body, and a bearing frame is arranged at the bottom end of the treatment tank body and used for supporting the treatment tank body. By means of the centrifugal impurity removal structure, the high-silicon ZSM-5 molecular sieve synthesis mother liquor is subjected to centrifugal treatment, layering occurs in the high-silicon ZSM-5 molecular sieve synthesis mother liquor, dregs contained in the high-silicon ZSM-5 molecular sieve synthesis mother liquor are guided into the filter residue cap groove, removal of filter residues of the high-silicon ZSM-5 molecular sieve synthesis mother liquor can be completed, the treatment effect can be improved, and the treatment cost of the filter residues can be controlled.

Description

technical field [0001] The invention relates to the technical field of molecular sieve production equipment, in particular to a treatment device for environmental protection recovery of high-silicon ZSM-5 molecular sieve synthetic mother liquor and a method for using the same. Background technique [0002] Molecular sieve is a synthetic hydrated aluminosilicate or natural zeolite with sieving effect. Its general chemical formula is (M'2M)O·Al2O3·xSiO2·yH2O, M' and M are monovalent and divalent cations such as K+, Na+, Ca2+, Ba2+, etc. It has many pores with uniform apertures and well-arranged holes in its structure. Molecular sieves with different apertures separate molecules of different sizes and shapes. According to the different molecular ratios of SiO2 and Al2O3, molecular sieves with different pore sizes can be obtained. Its models are: 3A (potassium A type), 4A (sodium A type), 5A (calcium A type), 10X (calcium X type), 13X (sodium X type), X (sodium X type), morden...

Problems solved by technology

[0003] The molecular sieve waste liquid treatment device on the market cannot quickly clean the filter structure during use, which affects the processing efficiency of the device. At the same time, the silica is not easy to settle during the treatment of the molecular sieve mother liquor, which can easily cause suspended solids in the sewage. Exceeding the standard, thus increasing the difficulty of sewage treatment
