Problems solved by technology

[0003] There are problems such as scaling, corrosion, and biological slime in industrial water systems. If they cannot be solved properly, energy consumption will be greatly increased, production efficiency will be low, and continuous operation will not be possible. also affect product quality
Although a large number of products such as descaling, anti-scaling, corrosion inhibition, and biocidal products have appeared in the market, none of them can solve the above problems well, especially the problem of secondary pollution, forming a vicious circle and further deteriorating the quality of circulating water
[0004] Due to the high salinity of water in the crude oil system, at the same time wax and asphalt will combine with calcium, magnesium, silicon, strontium, barium and other ions in the water, resulting in blockage of high-voltage electric pumps, crude oil delivery pipelines, and silting of crude oil storage tanks, causing serious damage to the crude oil system. It brings a lot of troubles, and the production cannot be carried out continuously and efficiently. Although the existing methods can barely maintain the production, there are still many imperfections;
[0005] In addition, in the heat transfer oil system, lubricating oil system, and hydraulic oil system, there are problems such as acidification, increased viscosity, carbon deposition, and system corrosion. The existing methods cannot solve the corrosion of the oil system due to oxidation, decomposition, and acidification, and the increase in viscosity , carbon deposits affect the normal operation of the system, etc.
[0006] In addition, the fuel oil and gas systems cannot fully contact with the combustion-supporting gas because the fuel is in an agglomerated state, resulting in insufficient combustion, and carbon deposits and low-temperature co-melt coking of sulfites are formed when sulfur exists, which not only wastes a lot of energy, but also Still a big security risk

Abstract

The invention discloses a preparation method of an electric shock / piezoelectric material and application of the electric shock / piezoelectric material in an industrial fluid system. The method includes: mixing a specific metal niobate composition with a rare earth oxide composition according to the mass ration of 4-5:1, grinding the mixture to powder with the mesh of 80+ / -5, and reducing for 300-310 hours at the high temperature of 6000+ / -100 DEG C to obtain the electric shock / piezoelectric material. The application includes: evenly dispersing the electric shock / piezoelectric material into corrosion-resisting alloy, titanium oxide or graphite in the mass ratio of 1:2-4, pouring or casting to a bulk or a cylinder, and performing finish machining for the bulk or the cylinder to a resistance-producing non-blocking orifice plate or a groove suitable for target fluid to contact with the electric shock / piezoelectric material. The electric shock / piezoelectric material is capable of preventing scaling, blocking and corrosion when used in an industrial fluid-liquid system, and is capable of increasing flame temperature and relieving coking of low-temperature eutectoids due to containing of elements of sulfur, phosphorus and the like when used in an industrial fluid-gas (combustion gas or combustion-supporting gas) system.
