Description

Vertical square multipul sections spacer diaphoresis tank

The utility model relates to paraffin de-oiling equipment.

Sweat tank is the key equipment of sweating deoiler during paraffin is produced.Present employed circular sweat tank (Fig. 1) is to grow up on the basis of pan sweating, though that this sweat tank has overcome the pan sweating floor space is big, consumable material is many, shortcomings such as operational condition difference.But because the event of its circular tube sheet has shape to determine, the arrangement of tube sheet edge cooling (heating) pipe is inhomogeneous.The tube side water import and export of circular sweat tank is located at the central position of two ends end socket respectively in addition, and the discharge in the tube side between each pipe is inhomogeneous.The reason of above-mentioned two aspects causes the shell side temperature distributing disproportionation even, thereby directly influences the yield and the quality of product.

The purpose of this utility model is to improve sweat tank shell side temperature distribution state, improves the quality of products and yield; Another purpose of the present utility model is to improve the sweat tank force-bearing situation, saves steel.Three of the purpose of this utility model is the amplifications that are beneficial to sweat tank, reduces the table of equipment number, is convenient to operation.

Vertical multi-sectional dividing plate sweat tank of the present utility model (Fig. 2) comprises member such as casing (shell) (11,12,17), tube bank 19, sieve plate 21, tube sheet 22, water distributor 23, supporting tube 20 and is provided with water inlet s, water outlet k, waxy stone inlet l, smart wax outlet j, waxy stone overflow port m, hand-hole r, thermopair interface p, pad water gangway q, thermometer boss n _1-2Deng.Its casing (11,12,17), tube sheet 22 and sieve plate 21 are square, and tube bank 19 is evenly distributed according to the shape of tube sheet 22 and sieve plate 21.Wherein casing 12 is a shell side, and upper box 17, lower box 11 are communicated with the tube side two ends respectively.The bottom is provided with a plate-like sparger 23 in the lower box 11, and water distributor 23 belows evenly have some apertures, and draw a water discharging hole i at the bottommost of lower box 11, and sidewall is opened a hand-hole r.An overflow card 18 is installed at the top of upper box 17, has evenly intensive aperture on the overflow card 18.Lateral dimension is enclosed within outside the upper box greater than the spill box 16 of upper box 17, and weld together with upper box 17, the bottom surface of spill box 16 is lower than overflow card 18 certain sizes, between upper box 17 outer walls and spill box 16, form a square ring-type overflow groove, on three orientation, spill box 7 bottoms, respectively open a hole and draw three pipes respectively, three pipes are pooled to water outlet manifold trunk 15 at the bottom of case, the water of tube side is caused water out.The loam cake of overflow card 18, spill box 16 is demountable structure, cooperates hand-hole r, can check the damaged condition of tube bank easily and repairs.

Make column 12-2 with four angle steel respectively, be welded by shell plating 12-1 all around for four jiaos of middle casing 12.Respectively there is a tube sheet 22 at middle casing 12 two ends, and tube sheet 22 and sieve plate 21 all are square, tube bank 19 shapes according to tube sheet 22 (square) uniform distribution.Middle casing 12 internal tube plates 22, sieve plate 21, tube bank are 19 all similar to existing circular sweat tank with the mounting means of supporting tube 20, different has two, the one, supporting tube 20 is directly outside a few pipes, without pull bar (Fig. 1 spare 5), reduced number of spare parts, the 2nd, the edge of

sieve plate

21 and 12 welding of middle casing are fixing, the load that alleviates tube sheet 22.The upper end of middle casing 12 has waxy stone inlet 1 and waxy stone overflow port m, and the middle part has thermopair interface p and thermometer boss n _1-2, its underpart has smart wax outlet j and pad water gangway r respectively.Middle casing 12 outer walls are provided with several stiffening rings 13 and hanger 14.

Compare with existing circular sweat tank, sweat tank of the present utility model is owing to adopt square structure, and it is more even to make that tube bank distributes, the distribution of particularly adjacent with shell edge tube bank.Improved tube side and gone out the entry mode, water inlet has added more effective water distributor, and tube bank top is provided with the overflow card, and above measure has been guaranteed respectively to manage the homogeneity of current, thereby the shell side temperature distribution is improved, and then improves product yield and quality.In addition, four angle steel of raising middle flask body and function are done to weld with body skin 12-1 the some stiffening rings 13 of coverboard peripheral hardware around the column, every layer of sieve plate and housing (middle casing) welding are fixing, have strengthened the housing supporting capacity, have alleviated the tube sheet load, can reduce the thickness of tube sheet and housing, save steel.Moreover because square structure is not subjected to the restriction of equipment making ability, the volume of sweat tank can amplify arbitrarily as required, thereby has reduced the sweat tank platform number of process unit, has made things convenient for operation.
