Description

A kind of Dao Ershi honeycomb inclined-tube filler settling tank

Technical field

The present invention relates to chemical industry sedimentation separation field, particularly relate to a kind of Dao Ershi honeycomb inclined-tube filler settling tank for heterogeneous system separation.

Background technology

At present, in Chemical Manufacture, the separation tool of heterogeneous system plays a very important role, by obtaining our required industrial products to its separation.Separation equipment also just becomes the key equipment in the separation of produced naturally, has very important status in the chemical separating operation.As a kind of novel separation equipment, the characteristics such as settling tank has the efficient height, takes up an area less, the cycle is short have begun extensive use in chemical industry and industrial department thereof.

Existing settling tank structure is: equipment body mainly is comprised of upper barrel body, lower skirt, central inner core, stirring mud-scraping apparatus, speed reduction gearing and six parts of power transmission shaft, wherein, upper barrel body by top blind flange, outer tube wall, inferior pyramidal at the bottom of three parts form, in top blind flange four uniform Qing Nikou are set, the cover plate below is close to a barrel wall an annular clean water overflow groove is set; Central authorities' inner core is divided into upper, middle, and lower part, and the upper and lower part is divided into columnar structured, and mid portion adopts cone structure; The equipment top arranges charging aperture, and the annular overflow trough position arranges the clean water overflow mouth, and the bottom at the bottom of the inferior pyramidal arranges rinse mouth and mud discharging mouth; A machine driving quaterfoil rotation mud-scraping apparatus is set at the bottom of the inferior pyramidal, and keeps certain interval with the inferior pyramidal bottom side, this device is connected with power transmission shaft, uses the worm-gear speed reducer control rate; Be divided into successively clear water zone, cloth pool, three parts of mud accumulation area by functional area equipment.

The use principle of this settling tank is as follows: feed liquid enters by certain radian from lower 0.3 meter of liquid level, inner core top, flows to urceolus through centrifugal sedimentation to the inner core thickening area and makes gravitational settling, and particle continues to sink and the clear liquid rising.0.6m place, top (clear liquid area) between inside and outside cylinder is provided with the liquid collecting gathering-device for the clear liquid overflow.Urceolus is for the feed liquid gravitational settling, and its top is cylinder, and the bottom is cone.Inner core is to separate charging and clear liquid, carries out centrifugal sedimentation for feed liquid in cylinder.The feed liquid that the top paddle is come in the top produces centrifugal motion, and its blade is upper and lower to be arranged at an angle of 90 and mutually along the direction of motion 30 degree angles that tilt, and the bottom is stirred sediment collection that rake separates inside and outside cylinder and held together the cinder notch that unloads to bottom central authorities.

There is following defective in this settling tank: clarification area is little, and long, weak effect of sedimentation separation time returns muddy easily in the larger situation of feed rate and the temperature difference; Power of motor is large, and the equipment operation energy consumption is high, and noise is large in the motor operation course, and manufacturing cost and the maintenance cost of equipment are large.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of Dao Ershi honeycomb inclined-tube filler settling tank that improves heterogeneous system separating effect.

For solving the problems of the technologies described above, the invention provides a kind of Dao Ershi honeycomb inclined-tube filler settling tank, its main body comprises vertical staving, skirt, central inner core, and central inner core places vertical staving central, and vertical staving is placed on the skirt; Described vertical staving is successively by forming at the bottom of top blind flange, outer tube wall, the inferior pyramidal, in top blind flange four uniform Qing Nikou and an access hole are set, the barrel upper end of cover plate below arranges an annular overflow trough, and bottom land is provided with overfall, and the bottom arranges rinse mouth and mud discharging mouth at the bottom of the inferior pyramidal; It is characterized in that: between the annulus between clear water zone and cloth pool intersection, central inner core and the staving, be provided with a honeycomb inclined-tube packing area, the honeycomb inclined-tube filler is the filling of individual layer ring type, with horizontal plane angle be 60 the degree, be provided with above the packing area press strip, below be provided with support bar; Cone angle at the bottom of the inferior pyramidal is 60 degree.

After adopting such structure, better help the separation of mud, water two-phase, the feed rate of settling tank increases greatly, has reduced the number of times of back-mixing; Muddy water separates by packing layer, and clarification area increases greatly, and the clear water come-up is passed through clear liquid area, mud deposits at the honeycomb inclined-tube tube wall, and gravitate descends automatically, passes the cloth pool to mud accumulation area, mud, water two are separated more thorough, have strengthened separating effect, have shortened disengaging time; Adopt gravity automatic mud removing mode (cone angle increases to 60 degree by 15 degree) at the bottom of the inferior pyramidal, abandoned stirring mud-scraping apparatus, speed reduction gearing and power transmission shaft, greatly reduce energy consumption and operating maintenance expense.

As improvement of the present invention, described central inner core is divided into upper and lower two parts, and top is circular straight barrel, the bottom is the loudspeaker enlarging, the inner core top arranges feed pipe and is connected with central inner core, and the two becomes 60 degree angles of cut, material under liquid 0.5 meter along central inner core with a radian spiral mode of entrance.

Like this, can constantly increase the separate and subside cross section remains under the viscous flow state feed liquid to separate, affect separating effect to avoid forming eddy flow; Avoid destroying the mudding layer, it is muddy to prevent that settling tank from returning, and further strengthens the pre-separation of mud, water two-phase, and it is relatively more balanced to make muddy water rise to distance and time of staying at top at the bottom of the bucket, reduces because the poor convection current that causes of severe.

As a further improvement on the present invention, described vertical staving adopts carbon steel material, and inner wall of barrel has been done the Corrosion Protection of Fiber Reinforced Plastics layer, and other inner members are coated with epoxy-based lacquers, and the honeycomb inclined-tube filler adopts macromolecule polymeric material.

Like this, the decay resistance of vertical staving improves, the erosion that filler can the establishment benzene homologues, and single device output increases, and efficient improves.

In sum, adopt the solution of the present invention, the improvement design by critical piece is carried out has realized desirable separating effect, has guaranteed the high-quality of production process, efficient, low consumption.
