Description
Technical Field
The utility model relates to a gas-solid splitter technical field especially relates to a high-efficient cyclone.
Background
The cyclone separator is an important gas-solid separation device, and has the advantages of simple structure, no moving parts, high separation efficiency, convenient maintenance, capability of working at high temperature and high pressure and the like, so that the cyclone separator is widely applied to the industrial fields of chemical industry, petroleum, environmental protection, food and the like. The working principle is that dusty airflow enters the cyclone separator through the air inlet, airflow rotating around the axis of the cyclone separator is formed in the cyclone separator, under the action of centrifugal force, dust is thrown to the outer wall and is discharged downwards through the dust discharge port, and clean gas is discharged through the central exhaust pipe. Since the airflow movement in the cyclone separator is very complex and belongs to strong cyclone of three-dimensional turbulence, the structural form of the cyclone separator directly influences the separation performance. The secondary vortex is ubiquitous in the cyclone separator and is composed of an axial velocity vz and a radial velocity vr, and the secondary vortex has a large influence on the performance of the cyclone separator, particularly on the separation efficiency. For example, as "upper vortex flow", a local vortex flow (upper vortex flow) is formed between the top cover of the cyclone dust collector, the outer surface of the exhaust pipe and the inner wall of the cylinder due to the existence of radial velocity and axial velocity, and carries a considerable amount of dust particles to flow to the center, and then the dust particles descend along the outer surface of the exhaust pipe and finally escape from the exhaust pipe along with the ascending air flow of the center, thereby affecting the separation efficiency. The "back-mixing" at the dust outlet also severely affects the separation of the fine particles by the separator. In a conventional cyclone separator, the descending airflow near the wall discharges the particles trapped at the wall into an ash hopper, so that inevitably a portion of the airflow enters the ash hopper and then returns to the separator, and this portion of the airflow returning from the ash hopper always carries back a portion of the separated dust, i.e. "back mixing". Therefore, the development of a cyclone structure capable of eliminating the secondary vortex and the back mixing phenomenon as much as possible is an important direction for improving the cyclone efficiency.
In addition, as the scale of industrial plant production increases and operating conditions become more demanding, the performance requirements for cyclones continue to increase. On the one hand, the cyclone separator is required to have stronger capacity for trapping fine powder; on the other hand, further reduction of the pressure drop in the cyclone is required to reduce the energy consumption. Therefore, there is an urgent need to develop a new cyclone separator with high efficiency and low energy consumption.
The chinese utility model patent application "a high-efficient low pressure drop cyclone separator" (grant No. CN207857151U) discloses a cyclone separator, which is provided with a plurality of balance holes on the pipe wall of the outlet pipe, the pore direction of the balance holes is opposite to the gas entering direction in the inlet pipe, and the solid particles are thrown into the lower cyclone through the balance holes under the action of centrifugal force, thereby improving the separation efficiency of the solid particles. The cyclone separator is not improved in structure to eliminate secondary vortex, the separation efficiency is not ideal, in addition, only a small part of dust particles are thrown out of the outlet pipe through the balance holes in actual operation, and the improvement proportion of the separation efficiency is very limited.
The Chinese patent application 'cyclone separator' (application publication number: CN 105750098A) discloses a cyclone separator, wherein an injection device is arranged on a top plate along the inner wall of an outer arc plate, so that the injection device can provide jet flow with a downward injection direction, the jet flow can inhibit secondary vortex in an annular space, an ash jacking ring is eliminated, and the separation efficiency of the cyclone separator is improved. The cyclone separator of the invention needs to strictly control the pressure and flow of the injected gas within a reasonable range, otherwise the injected gas interferes with the internal flow field of the cyclone separator, the efficiency of the separator is reduced, and related instruments and meters need to be added for monitoring related parameters of the injected gas. All such structures increase the difficulty of operation of the separator and increase the investment cost of the separator. Secondly, the requirement on the gas source of the injected gas is high, raw gas or inert gas is required, otherwise, the process gas treated by the separator is polluted, and the gas quality is influenced.
The invention discloses a high-efficiency low-resistance cyclone separator (application publication number: CN 101422757A), wherein an exhaust pipe is formed by sequentially connecting a straight cylinder, an upper flaring conical ring, a slotted cone and a lower flaring conical ring from top to bottom, and the lower end of the exhaust pipe extends into the junction of a cylinder body and the cone, so that the short circuit of dust particles is reduced, and the efficiency of the cyclone separator is improved. However, although the slotted cone of the invention is provided with the cone opening, the airflow enters the exhaust pipe through the cone opening, the flow area is increased, and the pressure drop of the separator is reduced, but the direction of the cone opening on the slotted cone is not opposite to the rotation direction of the airflow, so that a part of gas carrying dust directly enters the exhaust pipe from the cone opening and is discharged out of the separator, and the separation efficiency is reduced.
