Description
Technical Field
The invention relates to the field of equipment in petrochemical industry, coal chemical industry and the like, in particular to a built-in cyclone gas-liquid-solid separator, which is used for separating liquid and solid in gas.
Background
In industry, it is often necessary to remove dust from some industrial gases to filter out dust carried in the industrial gases, and high-performance mechanical dust removal techniques (such as cyclone dust removal techniques), high-performance barrier or dust removal techniques, electrostatic dust removal techniques, and the like can be used to remove dust from industrial gases.
The high-performance mechanical dust removing technology (such as cyclone dust removing technology) is a mature dust removing technology, has a simple structure, does not have rotating parts, and can be well suitable for running at high temperature. The cyclone dust collector realizes separation by utilizing centrifugal force generated when airflow rotates, solid particles move to the wall of the cylinder rapidly due to large mass and large centrifugal force, lose speed when colliding with the wall surface and move downwards under the action of inertia force and gravity, and thus, the separation of gas phase and solid phase is realized. Through the optimized design, the optimal dust removal effect of the existing monomer cyclone dust collector can remove particles with the particle size of more than 10 micrometers, and the dust removal efficiency of the particles with the particle size of 5-10 micrometers is about 85%.
The high-performance blocking or dust removing technology is mainly used for filtering on the surface, the penetration rate of dust particles is low, the dust removing efficiency can reach more than 99.9 percent, and the design life is short. At present, three types of filter are mainly particle bed filter, metal net filter and ceramic filter. The dust removal efficiency of the particle bed filter is up to 99%, the pressure drop is 4-8 KPa, particles with the particle size of more than 10 microns can be filtered, and the particle bed is easy to block in a high-temperature environment. The metal mesh filter is a filter screen woven by using special metal fibers, and the dust removal effect is influenced by the material. Due to the fact that the ceramic filter is different in structural form and different in performance of ceramic materials, the dust removal efficiency of the rigid ceramic filter can reach 99%, the rigid ceramic filter is suitable for high-temperature and high-pressure conditions that the temperature is 260-1093 ℃ and the pressure is reduced to 3.0-10 MPa, but the leakage of the rigid ceramic filter element affects the performance of the filter, not only is the dust removal efficiency reduced, but also the scaling and blocking operation difficulty of a subsequent washing system can be caused, and the whole production system is forced to stop in severe cases. The flexible ceramic filter can change the shape, the efficiency of the bag type dust collector reaches more than 99 percent, and 95 percent of particles with the particle size of 0.2 mu m can be removed. In addition, the high-performance barrier filter has high cost, high dust load in gas, high dust removal pressure drop and frequent ash removal, so that the high-performance barrier element is easy to damage.
The electrostatic dust removal technology has high dust removal efficiency of the electrostatic dust remover in a high-temperature and high-pressure environment, and the dust removal efficiency can reach 90-99.6 percent generally. The average particle size of the captured dust is 6 microns, and 3-5 levels of electrostatic field dust removal is adopted in China at the present stage, so that a relatively ideal purification effect can be achieved. The electrostatic dust removal technology mainly comprises a dry type electric dust removal technology and a wet type electric dust removal technology. The dry electrostatic precipitator collects dust particles by vibrating the dust. The wet electric dust collector mainly adopts the space of an electric field to transmit direct current negative high voltage, at the moment, gas in the space can be ionized, liquid drops and tiny particles in smoke are attached together, so that pollutant particles are captured, then the pollutant particles are placed in an automatic dust collecting plate, and dust particles are collected in a centralized mode. The gas humidity of the dry electric dust collector is very low, and the gas humidity of the wet electric dust collector is very high and generates a plurality of liquid drops. There are problems of corona stability, material stability, thermal expansion of the material, and the like.
At present, there are also dust collectors using a combination of high-performance mechanical dust removal technology (such as cyclone dust removal technology), high-performance blocking or dust removal technology, and electrostatic dust removal technology, for example, patent ZL98105707.1 discloses "dust collector and its operation method" in which cyclone dust removal technology and ceramic filtration technology are connected in series, and cyclone dust removal is used as pre-dust collection equipment by utilizing the performance of cyclone dust removal in high temperature, so as to reduce the dust load of ceramic filter. But because the ceramic filter system and the cyclone filter system are respectively and independently connected in series, the equipment cost is increased, and the system is complex and has low reliability.
The fly ash particles contained in the industrial gas have different sizes, for example, the fine ash particles contained in the synthetic gas have finer granularity, and when a high-performance blocking dust remover or an electrostatic dust remover is adopted, the early investment is large; the control difficulty and the safety of the system are increased in the operation process; the damage, scaling and blockage of the filter element, poor stability, replacement and the like cause frequent inspection and maintenance and influence the long-term operation of the device. The single cyclone gas-liquid-solid separator has the advantages that solid particles are thrown onto the cylinder wall under the action of centrifugal force, the cylinder wall is extremely easy to abrade and thin, potential safety hazards exist for a pressure bearing shell, and if wear-resistant materials are overlaid on the inner wall, the investment is increased, and the potential safety hazards exist. When the multistage single cyclone gas-liquid-solid separator is adopted for series/parallel operation, the equipment investment is increased, the occupied area is large, the control point and the control difficulty of the system are increased, and the complex potential safety hazard of the system is large.
