(2) background technology
Cyclone separator has been widely used in fields such as electric power, chemical industry, metallurgy, environmental protection.But the technical disadvantages of cyclone separator existence at present shows that mainly separative efficiency is low, solid back-mixing carries aspects such as phenomenon is serious, inner wall abrasion is serious.No. 97218705 patent disclosures of Chinese patent a kind of internally circulating cyclone separator, realize its method by installing center riser of inner barrel outside and bridging tube body, but still have certain deficiency aspect the wearing and tearing that solve whirlwind tube inwall.No. 97201351 patent disclosures of Chinese patent a kind of efficient cyclone separator that sprays discharging structure that has, discharge nozzle and removal device are connected as one, the removal device end is provided with nozzle, upper and lower pressure sensor is connected with adjustment control by the side pressure lead, realize efficient separation, carrying not effectively solution of phenomenon but the shortcoming that adopts this method is the back-mixing of particle, is disadvantageous to improving separative efficiency.
(3) technology contents
At the deficiencies in the prior art and problem, the invention provides a kind of gas-solid cyclone separation method and device thereof that reduces wearing and tearing, to reduce the degree of wear of particle to the cyclone separator inwall, effectively improve the gas solid separation efficient of cyclone separator, avoid oarse-grained back-mixing probability in the flue gas.
In order to reach above-mentioned goal of the invention, technical scheme of the present invention realizes in the following way:
A kind of gas-solid cyclone separation method that reduces wearing and tearing, the steps include: 1) flue gas that has certain flow rate and the carry flue dust flue gas horizontal inlet section by gas-solid separator tangentially direction enter the cyclone separator cylindrical shell, under the effect of centrifugal force and inertia force, the particle that flue gas carries is got rid of at a high speed to wall; 2) bulky grain in the flue gas is assembled to the inlet offside in cylindrical shell gradually, form oarse-grained concentrated phase area, the bulky grain of concentrated phase area enters at cylinder body outer wall along the opening on the cylindrical shell wall in the concentrated phase regional extent and connects discharge with endless screw pipeline under the screw, directly discharges by the returning charge leg of cyclone separator; 3) flue gas after being purified is discharged through the cyclone separator central tube.
A kind ofly adopt the above-mentioned device that reduces the gas-solid cyclone separation method of wearing and tearing, comprise the flue gas horizontal inlet section, cyclone separator cylindrical shell, awl tube, returning charge leg, cyclone separator central tube, the flue gas horizontal inlet section tangentially is connected with cyclone separator cylindrical shell top side, cyclone separator cylindrical shell bottom is connected with the awl tube, the bottom of awl tube is connected with the returning charge leg, and the setting of cyclone separator central tube is installed on the center on cyclone separator cylindrical shell top.Its design feature is, on the cyclone separator cylindrical shell wall on described flue gas horizontal inlet section opposite, offer opening, and from then on opening part begins to connect coarse granule spiral tremie pipe under the screw at the cyclone separator cylinder body outer wall, coarse granule spiral tremie pipe lower end directly and the returning charge leg join.
In above-mentioned device, opening is the strip opening, and its length, width and particular location can be adjusted according to the difference of flue gas flow rate, dust content, dust granularity and characteristic distributions.
In above-mentioned device, the pipeline section area of described coarse granule spiral tremie pipe diminishes from top to bottom gradually.
Method and device thereof that the present invention adopts; owing to made full use of the gas solid separation characteristics of centrifugation and inertial separation; directly the part particle is discharged; reduced the degree of wear of particle to the cyclone separator inwall; improved the gas solid separation efficient of cyclone separator effectively, avoided the bulky grain in the flue gas to mix to a great extent and returned probability.
