A kind of novel high-temperature air preheater is suitable for preheated air in the furnace treated black Production Flow Chart.In manufacturing technologies of carbon black, utilize the sooty high-temperature flue gas in air preheater, to carry out heat exchange, thereby preheated air reach the purpose that improves carbon black mass and yield with generation carbon black reaction required air.
At present, the domestic shell and tube air preheater that adopts more, air is walked shell side, flue gas is walked between the last lower tubesheet that the tube side heat-exchanging tube bundle is fixed on preheater, because the inhomogeneous temperature of respectively managing of flue gas flow between each pipe is unequal, the thermal expansion of each pipe is not waited, inequality between pipe and the shell expands in addition, cause the work-ing life of air preheater very short, after general 2-3 month, advance flue gas end tube plate deformation, the welding seam breaking of tube sheet and pipe causes air leaks, cause partial combustion, air preheater is damaged, and can't overhaul; In order to address this problem, taked complicated single tube equalising means abroad, complex structure involves great expense.
In order to overcome above-mentioned deficiency, the utility model has adopted the medium flow process opposite way of the air preheater of using with existing production of carbon black, its major technique feature is: air is walked tube side, carbon black smoke is walked shell side, structurally adopt single backhaul U type heat-exchanging tube bundle (6), be weldingly fixed on upper end tube sheet (7), upper end tube sheet (7) is connected with bolt with flange (4) on the housing (5), the lower end does not have tube sheet, tube bank (7) retractable.Fixedly the baffling rod (3) of heat transfer tube places between pipe, makes carbon black smoke become turbulence state to flow enhance heat transfer speed; Housing (5) inner lining as thermal insulation material (13), thus solved between the thermal stress issues and tube and tube that interchanger exists, inequality thermal expansion problem between pipe and shell, and it is also less that heat-exchanging tube bundle is stopped the influence of stove rapid heat cycle simultaneously; Owing to adopt new texture, also can make preheating of air to 450 ℃ with the heat-exchanging tube bundle of plain carbon stool material; Equipment has low cost, the advantage of long service life.
The present invention is achieved in that
Housing (5) is the square metal cylindrical shell, divide four sections, every intersegmentally connect with bolt by flange (4), seal with asbestos plate, housing (5) inner lining as thermal insulation material (13), heat-exchanging tube bundle (6) adopts U type list backhaul form, the upper end is welded on the upper end tube sheet (7), fixing between tube and tube with baffling rod (3), gas inlet takes over (11) and air is taken over (8) and plenum chamber (9) welding, and the centre separates with dividing plate (10), and dividing plate is welded on the upper end tube sheet (7), smoke inlet takes over (2) and exhanst gas outlet is taken over (12) liner refractory concrete backing layer (1), establishes hand-hole (14) and base (15) in the equipment bottom
Concrete structure of the present invention is provided by embodiment and accompanying drawing:
Fig. 1: new type high temperature air preheater structure iron
(1) refractory concrete backing layer, (2) smoke inlet is taken over, (3) baffling rod (4) flange, (5) housing, (6) heat-exchanging tube bundle, (7) upper end tube sheet, (8) air is taken over, (9) air plenum chamber, (10) dividing plate, (11) gas inlet is taken over, (12) exhanst gas outlet is taken over, (13) lagging material lining, (14) hand-hole, (15) base.
Describe details and the working condition of the concrete device that proposes according to the present invention in detail below in conjunction with accompanying drawing:
High-temperature air preheater is when operation, high-temperature flue gas is taken over (2) from smoke inlet and is entered shell side, making flue gas form turbulent flow through baffling rod (3) upwards flows, carry out heat exchange with the air in the heat-exchanging tube bundle (6), taking over (12) from exhanst gas outlet then flows out, air is taken over (11) from air intake and is entered plenum chamber (9), evenly distribute and enter heat-exchanging tube bundle (6), air in pipe, flow with manage outside flue gas carry out heat exchange, realize the purpose of preheated air, take over (8) from air outlet slit then and flow out.
Embodiment:
Housing (5) is 1200 * 1200mm square metal housing, wall thickness 8mm is divided into four sections, except that one section of base is the 3100mm, its excess-three section is each section of 2000mm has flange (4) to connect with bolt, the asbestos plate sealing, housing (5) inner lining as thermal insulation material lining (13), lagging material lining (13) is built by laying bricks or stones for light weeight alumina brick, thick 160mm; Heat-exchanging tube bundle (6) in the housing (5) is 55 in φ 57 * 3.5mm weldless steel tube, and pipe range 12000mm is processed into the U type, is welded on the upper end tube sheet (7), and its tube spacing is 75mm, arranged in squares; Place between pipe the fixing baffling rod (3) of heat transfer tube to adopt the stainless steel tube of φ 90 * 4.5 and φ 16 * 1.5, length is 800mm, and two ends are welded on the heat-exchanging tube bundle (6), the layout of baffling rod (3), every interlamellar spacing is 400mm, and adjacent two layers is crossed as 90 °; It is 1600mm that tube bank (6) lower end and smoke inlet are taken over (2) width between centers, makes flue gas evenly flow through heat-exchanging tube bundle (6); The plenum chamber on top (9) is of a size of 1200 * 1200 * 400mm, gas inlet takes over (11) and air is taken over (8) employing bi-directional symmetrical layout, central dividing plate (10) separates, dividing plate (10) is welded on the upper end tube sheet (7), it is two Dg300 pipes that gas inlet is taken over (11), and it is two Dg350 pipes that air is taken over (8); Smoke inlet is taken over (2) and is of a size of φ 650mm, and exhanst gas outlet is taken over (12) and is of a size of φ 600, the thick refractory concrete backing layer of liner 100～120mm (1).
