Abstract
The utility model relates to a heat exchanger, in particular to a mother liquor heat exchanger. A combined mother liquor heat exchanger with a graphite pipe provided by the utility model comprises a shell (1), wherein tube plates (2) are respectively arranged on the upper and lower ends in the shell (1), pores (5) are arranged on the tube plates (2), the upper and the lower pores (5) are connected via a graphite heat exchange pipe (3), and the inside diameter of the pore (5) is larger than the outside diameter of the graphite heat exchange pipe (3). The combined mother liquor heat exchanger of graphite pipe of the utility model has the advantages that the graphite material has a lower manufacturing cost, a longer service life and a better preservative effect compared with a metallic material.
Description
Technical field
The utility model relates to a kind of heat exchanger, relates in particular to a kind of mother liquor heat exchanger.
Background technology
Heat exchanger is a kind of important operation equipment that joins industrial departments such as alkali industry, and the tube sheet of heat exchanger of the prior art, heat exchanger tube all are to adopt metal material usually, the whole heat exchange weak effect of its equipment; Antiseptic effect is bad; Be prone to crystallization, wall built-up, and have spot corrosion, equipment manufacturing cost is high; Heat exchanger tube can't be changed, and easy complete machine is scrapped.
The utility model content
The technique effect of the utility model can overcome above-mentioned defective, and a kind of combined type graphite-pipe mother liquor heat exchanger is provided, and it can realize good heat transfer, sealing, antiseptic effect.
For realizing above-mentioned purpose, the utility model adopts following technical scheme: comprise housing, enclosure interior is provided with tube sheet respectively in two ends up and down, and tube sheet is provided with pore, and two pores connect through the graphite heat exchanger tube up and down, and the internal diameter of pore is greater than the external diameter of graphite heat exchanger tube.
Adopt graphite-pipe to be based on as heat exchanger tube: 1. the graphite heat conducting coefficient is very high; 2. the corrosion resistance and good of graphite; 3. graphite-pipe smooth surface, dirt is difficult for being attached to the surface; 4. the linear expansion coefficient of graphite is little, and heat resistance is good.Heat exchanger tube and tube sheet, deflection plate not only can be tightly connected effectively, and heat exchanger tube be heated can free wxpansion because the internal diameter of pore greater than the external diameter of graphite heat exchanger tube, has avoided causing because of the effect of thermal (temperature difference) stress the destruction of connecting portion.
Between tube sheet and the graphite heat exchanger tube high resiliency sealing ring is set, the high resiliency sealing ring adopts fluorubber or ethylene propylene diene rubber, has overcome the problem that solder joint corrosion that metal heat transmission equipment of the prior art causes because of material washes away makes seal failure.Because cushion rubber adopts plastic material, has good elasticity, and the metal heat exchanger tube directly is socketed on the cushion rubber, the pore that then cushion rubber is socketed on the metal tube sheets gets final product.
Staggered interval is provided with deflection plate in the housing, and the graphite heat exchanger tube runs through deflection plate.
Housing is provided with flange, and tube sheet adopts bolt to be connected with the flange of heat exchanger shell, is convenient to change the parts of damage like this, has overcome in the prior art owing to adopt the not easily changeable defective of connected mode of welding.Every graphite heat exchanger tube all can be changed separately, has avoided too much causing complete machine to scrap because of plugging.
Tube sheet adopts impregnated graphite or stainless steel or fiberglass or titanium alloy or carbon steel.
Graphite material is low with respect to its cost of metal material, long service life, and its antiseptic effect is better.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1. housing; 2. tube sheet; 3. graphite heat exchanger tube; 4. deflection plate; 5. pore; 6. flange; 7. bolt; 8. high resiliency sealing ring.
The specific embodiment
The heat exchanger of the utility model comprises housing 1, and housing 1 inner two ends up and down are provided with tube sheet 2 respectively, and tube sheet 2 is provided with pore 5, and two pores 5 connect through graphite heat exchanger tube 3 up and down, and the internal diameter of pore 5 is greater than the external diameter of graphite heat exchanger tube 3.
Between tube sheet 2 and the graphite heat exchanger tube 3 high resiliency sealing ring 8 is set.High resiliency sealing ring 8 adopts fluorubber or ethylene propylene diene rubber.Staggered interval is provided with deflection plate 4 in the housing 1, and graphite heat exchanger tube 3 runs through deflection plate 4.Housing 1 is provided with flange 6, and tube sheet 2 adopts bolt 7 to be connected with the flange 6 of heat exchanger shell.Tube sheet 2 adopts impregnated graphite or stainless steel or fiberglass or titanium alloy or carbon steel.
Because the improvement of structure and material can make the operation of heat exchanger temperature reach 100 ℃, operating pressure is brought up to 1.0MPa.
