Problems solved by technology

However, for high-viscosity wind power gear oil (kinematic viscosity is 320mm 2 / s@40℃) regeneration treatment adsorbent and its preparation method have not been reported yet, the main reason is that the viscosity of wind power gear oil is high at room temperature, and the polar aging products in the oil or the decomposition products of additives pass through the adsorbent. When the diffusion rate to the active center of the adsorbent is too low, the efficiency of removing aging products is too low, or the pressure difference of the oil regeneration filter is too large, which causes potential safety hazards of the equipment, so that industrial promotion cannot be carried out

Abstract

Disclosed are a strong polar mesoporous adsorbent for regeneration treatment of wind power gear oil and a preparation method of the strong polar mesoporous adsorbent. The adsorbent includes Si, Al, Ti and C with the mol ratio of (2-5):(1-5):1:(0.1-1.5). The adsorbent has a hole diameter of 10-50 nm and a specific surface area of 330-650 m<2> / g. The invention also discloses a preparation method of the adsorbent. The adsorbent has strong polarity, can fast effectively remove polar aging products, produced due to aging or additive hydrolysis, from oil, reduces the acid value of oil, improves foam characteristics of oil and removes oil sludge, so that performance indexes of the oil can be fully recovered. The adsorbent has the mesoporous feature so as to greatly reduce the differential pressure when the wind power gear oil is pumped to pass through a regeneration filter, so that the operational safety of a regeneration device is greatly improved. The preparation method is simple, and is mild in conditions, easy to operate, low in cost, and specifically suitable for massive production.

Description

technical field [0001] The invention belongs to the technical field of adsorbent for regeneration treatment of electric power oil, and in particular relates to a strong polar mesoporous adsorbent for regeneration treatment of wind power gear oil and a preparation method thereof. Background technique [0002] Wind power gear oil is mainly used in the speed-increasing gearbox of wind power generators as a medium for lubrication and heat dissipation. During the operation of the fan, due to the influence of external temperature, oxygen, moisture, metal catalysis and shear force, the aging of oil products and the decomposition and consumption of additives are inevitable. At present, wind power gear oil mainly uses fully synthetic polyalphaolefin as the base oil, and is formulated by adding excellent extreme pressure, anti-wear and anti-oxidation compound additives. Its price is about 10 times that of ordinary mineral lubricating oil. With the wide application of wind turbines, h...
