Universal type scale preventing device

Abstract

The invention relates to a scale preventing device, in particular to a universal type scale preventing device. Each scale preventing piece (6) is provided with a plurality of holes (3) penetrating through two side faces. The scale preventing pieces (6) are fixed to a spindle at intervals to form a scale preventing string and sleeved with a connecting pipe (5). One end of the connecting pipe (5) is sleeved with one end of a reducing connecting pipe (1), and the other end of the connecting pipe (5) is sleeved with one end of a connecting sleeve (11). The spindle comprises the chemical components of Ni(+Co), S, Al, Fe, Mn, Ti, C, Si and Cu. The electronegativity of alloy materials of the spindle is lower than that of ions in the liquid phase, so that the polarization effect of fluid is generated, and wax and colloidal substances in raw oil are in a suspended state and not prone to being adsorbed on the pipe wall in a gathered mode; and the purpose of preventing scales is achieved.

Description

【Technical field】 [0001] The invention relates to an anti-scaling device, in particular to a universal anti-scaling device. 【Background technique】 [0002] It is well known that petroleum plays an important role in the national economy. Petroleum is an important energy source. Compared with coal, it has high energy density (the heat of combustion of petroleum with equal weight is 50% higher than that of standard coal), convenient transportation and storage, and the degree of pollution to the atmosphere after combustion. Smaller and other advantages. Fuel oil extracted from petroleum is the main fuel for various kilns in transportation vehicles, power station boilers, metallurgical industry and building materials industry. Liquefied petroleum gas and pipeline gas, which use petroleum as raw material, are high-quality fuels used by urban residents. Airplanes, tanks, ships, rockets, and other spacecraft also consume large amounts of petroleum fuel. Therefore, many countries ...

AI Technical Summary

Problems solved by technology

Petroleum is a fluid mineral buried deep in the ground. In the process of oil exploitation, oil and gas flow from the reservoir to the bottom of the well, and then rise from the bottom of the well to the wellhead. The oil and gas extraction uses a tube pump, and the working principle is the working cylinder. A piston is arranged inside, and the lower part of the piston is fixedly connected to the swimming valve, and the swimming valve is reciprocated up and down to pump and press down. When the valve is pressed down, the valve is fixed to close the oil inlet hole, and at the same time, the oil stored in the working cylinder is squeezed from the floating valve to the oil storage pipe on the upper part of the piston, and the oil in the oil storage pipe on the upper part of the piston is lifted to the wellhead. After the general-purpose anti-scale device enters the ground equipment, there are many published patent documents on the current general-purpose anti-scale device "Using the structural transformation of the floating valve to form the anti-scale device", but most of them need to use power to make the anti-scale device work , a waste of electrical energy
