Description
Technical field
The utility model relates to high-temperature tail gas or process gas dedusting field, relates in particular to a kind of high temperature high-efficiency electromagnetic floating bed deduster based on gas-solid magnetically fluidized bed technology.
Background technology
At present, in the high-temperature dust removal technology of research and development, comparatively speaking, under higher temperature, filter the high-temperature dust removal technology and have more development prospect with rigidity ceramic filter and moving granular bed.The rigidity ceramic filter has high efficiency of dust collection and simple structure, and many countries fall over each other research and development, has entered the demonstration operation of 200～300 ℃ of scopes, but under higher temperature, Yin Wendu and mechanical shock have but occurred and difficult problems such as embrittlement or seal failure.And moving granular bed has the good temperature resistance energy, particularly the moving granular bed filtering technique has overcome the shortcoming that in the past can not move continuously, make the dust removal by filtration process stablize continuously, be considered to the tool high-temperature dust removal technology of development prospect with the rigidity ceramic filter.
Although moving granular bed filter has development prospect, and many experiments under the hot gas condition, have been carried out, but because the complexity of its structure and operation, theory and operation practice to its research at present also is nowhere near, especially under high temperature, high pressure, have many problems to need to solve the following problem of ubiquity:
(1) the domestic reverse-flow moving granular bed filter report that is used for the high temperature and high pressure gas filtration studies is fewer.The filter of external this type also carries out dedusting research mostly under flue gas condition, the experimental study under the heating gas condition is also less.(2) the stratum granulosum deashing recirculating system that is adopted in the world, main form are that vibrosieve deashing and machinery are proposed the bucket circulation, are not suitable for hot operation, have seriously restricted moving granular bed filter and have entered through engineering approaches.
(3) forefathers have carried out the research of strength circulation deashing under experiment of a large amount of normal pressures, high temperature moving bed granular bed filter and the normal pressure, but the domestic report that does not still have the integrated operation of granular bed filter and strength deashing under the high pressure.
Summary of the invention
The purpose of this utility model provides a kind of high temperature high-efficiency electromagnetic floating bed deduster, utilizes the effect of externally-applied magnetic field to make micron-sized magnetic powder material suspension form the unsteady bed of porous, makes the grit in the dusty gas that passes through obtain isolated by filtration.
For solving the problems of the technologies described above, the technical solution of the utility model is:
High temperature high-efficiency electromagnetic floating bed deduster, it is characterized in that, comprise tank body, magnetic powder, solenoid, pressure difference transmitter, control power supply, air inlet, gas outlet, magnetic powder is filled in the vertical tank body, a plurality of solenoids that be arranged in parallel on the vertical tank body stack shell, tank base is provided with air inlet, and the tank body top is provided with the gas outlet, the pressure difference transmitter sensor is arranged in the tank body of solenoid above and below, and the control power supply is connected with solenoid, pressure difference transmitter respectively.
Described tank base also is provided with ash discharging hole.
Compared with prior art, the beneficial effects of the utility model are: (1) has solved a difficult problem that removes impurity such as dust, tar droplet under high temperature, the high pressure in process gas/tail gas, thereby eliminates obstruction that thing such as dust/tar causes pipeline in the subsequent handling and to the influence of equipment performance etc.; (2) have that gas-solid contacts, advantages such as efficiency of dust collection height, flow area are big, no gas short circuit, that filter material upgrades is convenient, suitable continuous operation; (3) dedusting precision 2.0 μ m reach efficient fine dedusting, reduce the final purpose of dust pollution, have a wide range of applications.
