Abstract
The utility model relates to a glass enameled pipe heat exchanger with elliptic tube plates. The tube plates form an ellipse shape, and a tube bundle and tube plates are movably connected in packing seal. The connection of a casing and the tube plates can be welding closed type at the two ends, can be welding closed type at one end and open type fastened by a tank clamp and can also be open type at the two ends. The contact surface of the reaction medium of the shell pass is made of glass enameling, and the outer of the casing can be provided with a jacket. The utility model has the advantages of low enamel burning difficulty, steel saving and low cost, so the utility model is a feasible technical proposal that the manufacture of glass enameled pipe heat exchanger with large diameter, large heat exchange area and high working pressure comes to be true.
Description
The utility model relates to tubular heat exchanger category in the chemical industry equipment, particularly a kind of oval tube sheet shell side enamel tubular heat exchanger.
Heat exchanger is a process equipment important in chemical industry, the pharmaceutical manufacturing, and tubular heat exchanger has the structure compactness in the heat exchanger same clan, the heat exchange efficiency height, and the advantage that heat exchange area per unit volume is big is so be widely used.
Enamel, also name acid-proof enamel or chemical enamel is that the high enamel of working face spraying silicon content at steel equipment forms through high temperature sintering.Its not bridging of any surface finish can the isolating metal ion, has the superior corrosion resistance energy, so be widely adopted in chemical industry, pharmaceuticals industry.
At present, because the enamel firing technical limitations, prior art can only be processed the enamel heat exchanger of telescopic or chip, and volume is big, and heat exchange efficiency is low, and the cost height is their deadly defect.
CN94240124.7 provides a kind of shell side enamel tubular heat exchanger of novelty, the brilliant prospect of having showed the enamel tubular heat exchanger for us.But because of its tube sheet is flat, still exist stressed bad, when particularly making the high heat exchanger of major diameter and working pressure, its tube sheet must design quite thickly, it is big not only to consume steel material, and because of tube sheet thicken to enamel firing bring because of the asynchronous defectives such as enamel firing distortion that cause that heat up, can not be fully up to expectations.
Goal of the invention of the present utility model is improved above-mentioned the deficiencies in the prior art exactly, designs a kind of oval tube sheet shell side enamel tubular heat exchanger.
Design of the present utility model realizes with following technical proposals:
Manufacture and design a kind of tubular heat exchanger category that belongs to, the main oval tube sheet shell side enamel tubular heat exchanger of being made up of housing, end cap, tube sheet and tube bank is characterized in that:
A. the section shape of tube sheet (8) is oval,
B. tube bank (6) adopts the high movable packing seal to be connected with tube sheet (8),
C. housing (4) can be that two ends are the welding enclosed, end welding enclosed one end is to be by jar fastening open type of clamp (12) by jar open type that clamp (12) is fastening or two ends with being connected of tube sheet (8),
D. the reaction medium contact-making surface of shell side all is the enamel material,
E. can there be chuck (5) housing (4) outside.
Above-mentioned oval tube sheet shell side enamel tubular heat exchanger, the section shape that it is characterized in that described tube sheet (8) is oval, the section shape that is meant two ends tube sheet (8) all is oval, the curved surface of tube sheet (8) and end cap (10) in the same way, the pore place has the outside kiss shape structure of nose.
Above-mentioned oval tube sheet shell side enamel tubular heat exchanger, it is characterized in that described tube bank (6) and tube sheet (8) adopt the high movable packing seal to be connected, be meant that tube bank (6) is by in the fastening corresponding pore that is assemblied in oval tube sheet (8) of grommet (15), filler (16) and gland (14).
Above-mentioned oval tube sheet shell side enamel tubular heat exchanger, it is characterized in that described housing (4) and being connected of tube sheet (8) can be that two ends are the welding enclosed, end welding enclosed one end is to be by jar fastening open type of clamp (12) by jar open type that clamp (12) is fastening or two ends, be meant that the housing (4) and the connected mode of tube sheet (8) can be:
Two ends all directly are welded as enclosed, add hand-hole,
Or one end directly be welded as enclosed, the other end adds hub flange (3) for by the fastening open type of jar clamp,
Or two ends are by the fastening open type of jar clamp, add hub flange (3).
Above-mentioned oval tube sheet shell side enamel tubular heat exchanger is characterized in that the reaction medium contact-making surface of described shell side, all is the enamel material, is meant:
The inner surface of housing (4), tube sheet (8) and seal box (2), the outer surface of tube bank (6) all are the enamel materials.
Compared with the prior art, the utility model:
1. in the design of shell side enamel tubular heat exchanger, adopt oval tube sheet, not yielding in the enamel firing enamel process; Because of stressed good, can be designed to thin tubesheet, even tube sheet and housing reduced the enamel firing difficulty with thick, save steel, reduce cost; Tube sheet itself also becomes heat exchange area, under the kindred circumstances, can increase heat exchange area about 10%.
2. the design's heat exchanger, housing and tube sheet can adopt multiple connected mode, as:
Housing and tube sheet directly are welded as enclosed, add hand-hole, reduce two secondary hubbed flanges, jar clamp, pad etc., and avoid causing leakage because of pad damages; Make, assemble, keep in repair easy; Tube sheet and housing become one, and the enamel firing number of packages reduces, and improve enamel firing efficient.
Enclosed connects and to be suitable for diameter greater than the heat exchanger more than the φ 1300mm, and diameter is less than can making an end enclosed one end open type below the φ 1300mm, or two ends are open type.
3. the design installs pass partition to the major diameter heat exchanger additional in end cap, shell side, can make multitube journey and muitishell, increases the distance of two medium heats exchange, and makes two medium reverse flows, improves heat exchange efficiency.
4. being connected of heat-exchanging tube bundle and tube sheet, adopt high movable packing seal syndeton, need not to add expansion joint, can regulate internal stress voluntarily, avoid housing different, expand asynchronous and cause being out of shape the enamel layer damage that causes with the heat-exchanging tube bundle temperature.
5. modular construction is easy to remove incrustation scale and changes the parts that damage, and prolongs complete machine service life.
6. the scope of application is wide, to gas, liquid medium can both heat, heat exchanging process such as cooling, condensation.Can horizontal or vertical installation, be convenient to chemical industry, pharmaceutical technology is arranged.
Facts have proved that present design makes makes major diameter (for example more than the φ 1300mm), big heat exchange area (100m for example
2More than) and the enamel tubular heat exchanger of working pressure height (for example 1MPa above or high vacuum) become a reality, market prospects are wide, economic benefit and social benefit be highly significant all.
