What are the structure types of conventional metal separators?

In order to improve the performance of conventional metal separators, over the years, experts and scholars have designed and manufactured metal separators with various structural forms, which are mainly divided into six categories. Now, let's take a look with Kenwei Technology. 1. Diffusion type metal separator The main feature of the diffusion type metal separator is that about 10% of the air flow is drawn out from the dust outlet of the metal separator to improve the separation efficiency. Dust does not accumulate on the wall surface, which reduces the blowing of the bottom; secondly, when dealing with sticky dust, the blockage of the dust outlet can be avoided. 2. Bypass type metal separator The bypass type metal separator is characterized in that the solid phase particles accumulated in the upper dead corner of the device body (ie the upper ash ring) are directly sent to the vicinity of the dust outlet through the bypass to reduce short circuit The leakage of the flow improves the separation efficiency of small particles. 3. Metal type metal separator Metal type metal separator is also called tornado type metal separator, its structure and working principle are shown. The dust-laden gas is introduced from the lower part, turns into an upward-rotating airflow through the guide vanes, and the upper part is then introduced into the downward-rotating secondary air. The rotation direction of the wind is consistent with the rotation direction of the middle dust-laden airflow, which can strengthen the rotation intensity of the dust-laden airflow. , so that the solid-phase particles generate greater centrifugal force and are separated. At the same time, the separated particles are discharged through the dust discharge annular gap under the action of the secondary air, and the purified particles are discharged upward from the center. The solid phase particles in the metal zone are separated again before being discharged from the separator. The double exhaust pipe type metal separator manufactured by our company can give the particles entrained in the inner metal a chance to separate again, and the total separation efficiency is very high. The high-efficiency metal separator made by the former Soviet Union is mainly characterized by three concentric overflow ports. After the fluid enters the cylindrical part, the solid phase particles are thrown away under the action of centrifugal force To the inner wall, and then spiral down, discharged through the bottom flow port, and the light part is discharged from each overflow port. The metal separator of this structure can improve the processing capacity and the purification degree of the liquid, and reduce the internal hydraulic loss. 5. Central Solid Rod Metal Separator Xu Hongqing of Lihua University tested the inner flow field of the metal tool with a laser velocimeter, and found that in the central area of u200bu200bthe metal tool, the tangential velocity was reduced and the turbulent dissipation was strong, and this part of the flow increased The pressure loss of the separator reduces the performance of the separator. According to this, a solid mandrel is added to replace the forced vortex in the center of the m4 double exhaust pipe type hepta air separator in the metallizer. The experimental test results show that the central strong turbulence area has been completely removed, and the pressure loss coefficient is reduced by 33% under open-loop operating conditions. 6. Multifunctional metal separator In order to solve the long-standing problem of high consumption and low efficiency of oil drilling fluid solid control equipment, Jianghan Machinery Research Institute is developing a new high-efficiency The multifunctional metal separator is mainly composed of a cylinder body, a cone cylinder, a slurry feeding pipe, a body side arm, a swirl arm, a central pipe and an overflow pipe. This kind of separator not only has the advantages of simple and reliable conventional metal separator, but also has the characteristics of multi-stage shunt, control of influent concentration and stable operating conditions. It can simultaneously separate large solid phase particles and tiny colloidal particles from the drilling fluid, so as to control the solid phase particle size distribution of the drilling fluid in an ideal state; it can also remove chemical pollution to the drilling fluid. , to maintain the excellent rheology of drilling fluid. The product has achieved remarkable results through flow field research and performance test. Under the condition of processing the same flow of drilling fluid, the working pressure of the multifunctional metal separator is 16.7% lower than that of the conventional metal separator, the density of the separated underflow is 20% higher, and the solid content of the underflow is 214.5% higher. Both theory and practice show that the multifunctional metal separator has high efficiency and low consumption, and has strong separation ability, and is a promising petroleum solids control equipment.
