Description
Technical field
The utility model relates to a kind of corrosion-resistant silicon carbide heat exchanger, relates generally to the anti-corrosion heat exchanger of a kind of chemical industry, food and medicine production process, is applicable to containing the condensation of corrosive materials, cooling and heating.
Background technology
Corrosion-proof heat exchanger is absolutely necessary one of equipment in chemical industry and medicine production, no matter that to apply in industry and civilian heat exchange be very widely, its importance is also apparent, and the height of heat transmission equipment utilization rate directly has influence on the cost issues of industrial production efficiency and cost.According to valid data display, heat exchanger accounts for 20% of investment in medicine and chemical industry construction, and therefore, the utilization rate of heat exchanger and life-span are the major issues being worth research.By the source of damage of heat exchanger, corrosion is a very important reason, and the corrosion of heat exchanger is a large amount of ubiquitous.At present in medicine, chemical industry, the recovery containing strong acid, strong basicity gas is a larger problem, and the most of contaminative of the material itself due to strong acid alkalescence own is stronger, as direct discharge, will cause the consequence of fearful environmental pollution.But the metal material common due to strong acid (material that pH value is less than 3), highly basic (pH value is greater than 12) cannot bear its severe corrosive.The condenser of current stainless steel material can only use when the weak acid alkali of some not chloride ion-containing, the metal material of some special type also can have good tolerance to part strong acid-base, as titanium alloy material, Hastelloy etc., but the cost of this kind of material is generally higher, be 10-20 times of price of 50-100 times of price of the carbon steel condenser of equal capability, stainless steel condenser, because cost is too expensive, general producer does not consider to use.Glass heat exchanger, the heat exchange efficiency of this heat exchanger is low, and frangible, installs and safeguards all inconvenient.Enamel heat exchanger, heat transfer coefficient is low, and heat transfer effect is poor, and in the process of cold and hot exchange easy sudden and violent porcelain.Graphite heat exchanger, not withstand voltage, sealing effectiveness is poor, and maintenance cost is also higher.
For this problem, producer is had to make carborundum tubular heat exchanger according to the form design of common shell and tube condenser at present, carborundum is utilized to complete the recovery to strong acid alkaline gas for the excellent tolerability of strong acid-base, the inorganic acid of the carbofrax material ability overwhelming majority, organic acid, organic solvent and highly basic.But due to inconsiderate during this kind of design of condenser, what carborundum tube adopted is silicon carbide reaction-sintered, and the coefficient of heat transfer is low, and corrosion-resistant intensity is low, more crisp easy fracture.The connection of tube hydroforming adopts glue to pick up the mode of conjunction, and the corrosion of organic solvent-resistant and high pressure, easily do not reveal, cause very large economic loss.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides that a kind of heat exchange efficiency is high, energy consumption is little, fouling tendency is low, and corrosion resistance is high, carborundum tubular heat exchanger easy to maintenance.
The purpose of this utility model is achieved in that a kind of corrosion-resistant carborundum tubular heat exchanger, comprise housing, the carborundum heat exchanger tube that many transverse directions are arranged in parallel is provided with in described housing, each root carborundum heat exchanger tube is fixed on tube sheet by bolt presses assembly, described tube sheet is arranged between housing and end cap, bolt-locking is passed through between housing and end cap, described many carborundum heat exchanger tubes are vertically interspersed with multiple deflection plate, described bolt presses assembly comprises seal cartridge assembly in the through hole that is set in turn in and tube sheet is offered and endoporus locking nut, one end of carborundum heat exchanger tube is connected with end cap with after endoporus locking nut through seal cartridge assembly successively.
Compared with prior art, the beneficial effects of the utility model are:
1, adopt carborundum that heat exchanger tube decay resistance is strengthened, extension device service life.
2, the heat exchange efficiency due to carborundum is higher, therefore greatly can improve the heat exchange efficiency of whole heat exchanger, reduce the smaller volume of heat exchanger simultaneously.
3, heat exchanger tube adopts the single combination sealing of the combination of V-seal cover and screw tightening sealing shroud, makes not easily to leak in heat transfer process, high temperature high voltage resistant.
4, owing to adopting single heat exchanger tube to seal, make easy to maintenance.

Detailed description of the invention
See Fig. 1, the utility model relates to a kind of corrosion-resistant carborundum tubular heat exchanger, comprise housing 1, housing 1 is enamel housing or Stainless Steel Shell, the thin-walled pressureless sintering carborundum heat exchanger tube 2 that many transverse directions are arranged in parallel is provided with in described housing 1, described many carborundum heat exchanger tubes 2 are fixed on tube sheet 4 by bolt presses assembly 3, tube sheet 4 is polytetrafluoroethylene (PTFE) tube sheet or composition metal tube sheet, described tube sheet 4 is arranged between housing 1 and end cap 5, bolt-locking is passed through between housing 1 and end cap 5, described many carborundum heat exchanger tubes 2 are vertically interspersed with multiple deflection plate 6, deflection plate 6 is polytetrafluoroethylene (PTFE) deflection plate, exhaust outlet 7 and charging aperture 8 is provided with above described housing 1, below is provided with discharge gate 11, water inlet 9 and delivery port 10 is respectively arranged with above described end cap 5.
See Fig. 2-3, described tube sheet 4 offers with carborundum heat exchanger tube 2 equal number with arrange identical through hole 4.1, described through hole 4.1 is shoulder hole, described bolt presses assembly 3 comprises V-seal grip assembly 3.1 and endoporus locking nut 3.2, the sealing shroud that described V-seal grip assembly 3.1 is V-type face by multiple two ends forms, be positioned at the middle shoulder hole of through hole 4.1, the outside shoulder hole of through hole 4.1 is screwed hole, described endoporus locking nut 3.2 is positioned at screwed hole and is locked by V-seal grip assembly 3.1, V-seal grip assembly 3.1 and endoporus locking nut 3.2 are passed successively by the inner side shoulder hole of through hole 4.1 in one end of described carborundum heat exchanger tube 2, because carborundum thermal coefficient of expansion is little, carborundum tube bank and the flexible difference caused because thermal coefficient of expansion is different between shell easily cause connecting tube sheet and extend with shell and cause seal failure at relatively high temperatures, the V-seal grip assembly formed due to multiple sealing shroud can provide a flexible cushion space when expanding with heat and contract with cold to carborundum heat exchanger tube, therefore the seal failure caused because expanding with heat and contract with cold can be made up.
