Background technology
Cyclone separator has been widely used in electric power, chemical industry, metallurgical, fields such as environmental protection, it is the dust that is commonly used in the divided gas flow, when the dust in the gas rotates in cyclone separator with air-flow, because action of centrifugal force, the dust granules that inertia mass is bigger in the air-flow at first can depart from the air-flow that rotatablely moves, wall motion towards cyclone separator, near the bottom ash releasing tube that is concentrated in the wall of cyclone separator and finally falls efficient cyclone separator along wall is collected discharge, the less dust granules of gas and inertia mass is then done top-down king bolt motion in the circular cylindrical shell in cyclone separator, air-flow can shrink screw radius and acceleration after entering the awl cylinder shell, the inertia mass smaller particles also can be concentrated near concentrated discharge of bottom ash releasing tube quilt of also finally falling cyclone separator along wall the wall of cyclone separator gradually, gas after the dedusting is done minor spiral motion from bottom to top again from the bottom of cyclone separator, the exhaust outlet that enters the top is discharged.There is following problem in such cyclone separator at present: 1, because the housing Internal and external cycle has downward spiral air flow, inner ring is upwards spiral air flow, and the gas that is entered by air inlet pipe is not controlled slightly with regard to being easy to the air-flow of adjacent two spiral coils is interfered with each other, and influences ash discharge efficient; 2, exhaust outlet is usually located at case top, and purified gas is directly discharged by top vent, easily causes the bigger pressure loss; 3, be not suitable for hot environment, as the cracking gas that produces in the brown coal drying process, contain the coal tar of high temperature in the large-minded and cracking gas, worst hot case (300-400 ℃) down dedusting cause the inner walls serious wear; 4, cause complex structure in order to improve separative efficiency.
Summary of the invention
The purpose of this utility model is in order to solve the problems of the technologies described above, and a kind of simple in structure, erosion resistant, separative efficiency height, high temperature efficient cyclone separator that the pressure loss is little are provided.
Technical scheme comprises the cone barrel housing, is positioned at air inlet pipe, blast pipe and ash releasing tube on the housing, be provided with vortex controller in the housing, inner walls is lined with refractory liner, and epimere is provided with the cone expansion pipe in the housing, and described blast pipe tangentially is communicated with the cone expansion pipe through housing epimere sidewall.
Described air inlet pipe is a rectangle, tangentially is communicated with in housing epimere sidewall and housing.
Downward-sloping 5 °～20 ° of described air inlet pipe front end.
Described cone expansion pipe is made of tapering up big and down small two sections conically shapeds and a cylindrical section.
Awl tube top also is provided with the heat shield liner top.
Described heat shield liner top section is a triangle, and described leg-of-mutton ogival is positioned on the center line of housing.
Beneficial effect:
1. the refractory liner that is lined with by inner walls improves its high temperature resistant and erosion resistant ability, has prolonged service life, satisfy under the bad working environments also can operate as normal requirement, safeguard easily manufactured.
2. utilize cone expansion to guarantee to hold the pressure of the spiral air flow that inner ring rises, effectively reduce the pressure loss in the cyclone separator, cooperate the blast pipe that tangentially is connected with housing, make the gas of discharge revolve the direction discharge that spiral changes along inner ring, further reduce the pressure loss, improve separative efficiency.
3. be rectangle with Inlet Manifold Design, equally tangentially be connected with housing, the assurance air inlet is revolved the spiral veer and is entered along the outer ring, and downward-sloping 5 °～20 ° of air inlet pipe front end, can make gas and level be 5 °～20 ° downward-sloping rotating, the gas that tilts to enter helps avoiding the air-flow of inside and outside adjacent two spiral coils to interfere with each other, and significantly improves separative efficiency.
4. be filled with thermal insulating filling in the heat shield liner top, can reduce thermal loss; Leg-of-mutton ogival is positioned on the center line of housing, has the effect in further steady whirlpool.
5. the utility model is based on the design of separating flowing field optimization and control, it is simple in structure, be convenient to make and safeguard, can be in bigger tolerance process range (pneumatic excursion is at 70%-130%), keep the very high separative efficiency (separative efficiency reaches 99.5%) and the very little pressure loss (pressure loss is not more than 1.4 kPas), and keep operation steady in a long-term easily.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further explained explanation:
With reference to Fig. 1, the housing 1 of cone barrel is made of cylindrical section 1.1 and conical section 1.2, and its inwall is lined with ganoid refractory liner 1.3, and it is leg-of-mutton refractory lining top 1.4 that the top is lined with the cross section, and leg-of-mutton ogival is positioned on the center line of housing 1.Described housing 1 is provided with air inlet pipe 2, blast pipe 5 and ash releasing tube 3, and the top is provided with cone expansion pipe 6 in the housing 1, and the below is provided with vortex controller 4.Described air inlet pipe 2 is a rectangle, downward-sloping 5 °～20 ° of front end, and tangentially in housing 1 epimere sidewall and housing 1, be communicated with.Described blast pipe 5 also tangentially is communicated with cone expansion pipe 6 through housing 1 epimere sidewall, and described cone expansion pipe 6 is positioned at housing 1 epimere, is made of the up big and down small upper conical-tube 6.1 of tapering, slower conical tube 6.2 and a cylindrical section 6.3.Described ash releasing tube 3 is positioned at the lower end of housing, is used to collect flue dust.
Operation principle:
The high-temperature gas of dust-laden (300-400 ℃) enters from rectangular air inlet pipe 2, because downward-sloping 5 °～20 ° of air inlet pipe 2 front ends, make gas also be 5 °～20 ° downward-sloping outer rings in housing 1 and do the king bolt motion with level, the gas that tilts to enter helps avoiding the air-flow of inside and outside adjacent two spiral coils to interfere with each other, enter housing 1 back air-flow and can shrink screw radius and acceleration, dust granules in the gas is under centrifugal force and inertia force effect, be thrown toward wall, take particle to ash releasing tube 4 by near the downward king bolt air-flow in the outer ring inwall and discharge; The vortex controller 4 auxiliary minor spiral eddy current that produce stable separation eddy and the rising of guiding formation inner ring, make gas behind the purifying and dedusting along cylinder 6.3, slower conical tube 6.2, upper conical-tube 6.1, and blast pipe 5 discharges tangent with housing 1, circular cone convergent divergent channel 6 can effectively reduce the pressure loss in the cyclone separator, under design conditions, the separative efficiency of this new type high temperature efficient cyclone separator reaches 99.5%.
