The silicon carbide tube heat exchanger is high in heat exchange efficiency, low in energy consumption, high in corrosion resistance and convenient to maintain and is not prone to scaling.
Description
Technical field
The present invention relates to a kind of corrosion-resistant silicon carbide heat exchanger, relates generally to a kind of chemical industry, the anti-corrosion heat exchanger of food and medicine production process, it is adaptable to the condensation containing corrosive materials, cooling and heating.
Background technology
Corrosion-proof heat exchanger is one of requisite equipment in chemical industry and medicine production, it is quite varied either to apply in industrial and civilian heat exchange, its importance is also it will be apparent that the height of heat transmission equipment utilization rate directly influences the cost issues of industrial production efficiency and cost.Show according to valid data, heat exchanger accounts for 20% for investing in medicine and chemical industry construction, therefore, the utilization rate of heat exchanger and life-span are the major issues for being worth research.From the point of view of the cause of damage of heat exchanger, the reason for corrosion is one particularly significant, and the corrosion of heat exchanger is substantial amounts of generally existing.At present in medicine, chemical industry, the recovery containing strong acid, strong basicity gas be one than larger problem, as the most of contaminative of the material itself of strong acid alkalescence itself is stronger, such as directly discharge will cause the consequence of fearful environmental pollution.But due to strong acid（Material of the pH value less than 3）, highly basic（PH value is more than 12）Common metal material cannot bear its severe corrosive.The condenser of current stainless steel material can only be used in the case of some not the weak acid alkali of chloride ion-containing, some extraordinary metal materials can also have good tolerance to part strong acid-base, such as titanium alloy material, Hastelloy etc., but the cost of this kind of material is generally higher, it is 50-100 times of price of the carbon steel condenser of equal ability, 10-20 times of price of stainless steel condenser, as cost is prohibitively expensive, general producer does not consider to use.Glass heat exchanger, the heat exchange efficiency of the heat exchanger are low, and frangible, install and safeguard all inconvenient.Enamel heat exchanger, heat transfer coefficient are low, and heat transfer effect is poor, and the easily sudden and violent porcelain during cold and hot exchange.Graphite heat exchanger, not pressure, sealing effectiveness is poor, and maintenance cost is also higher.
For this problem, there is producer to make carborundum tubular heat exchanger according to the form design of common shell and tube condenser at present, using carborundum for the excellent tolerability of strong acid-base completes the recovery to strong acid alkaline gas, carbofrax material is resistant to most of mineral acid, organic acid, organic solvent and highly basic.But due to inconsiderate during this kind of design of condenser, carborundum tube uses silicon carbide reaction-sintered, and the coefficient of heat transfer is low, and corrosion-resistant low intensity, the crisp easy fracture of comparison.Pipe is connected by the mode that glue picks up conjunction with tube sheet, not the corrosion of organic solvent-resistant and high pressure, easily reveals, causes very big economic loss.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency, there is provided 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 object of the present invention is achieved like this：A kind of corrosion-resistant carborundum tubular heat exchanger, including housing, the many carborundum heat exchanger tubes being parallel transversely disposed are provided with the housing, each carborundum heat exchanger tube is fixed on tube sheet by bolt presses component, the tube sheet is arranged between housing and end cap, locked by bolt between housing and end cap, multiple deflection plates are interspersed with vertically on many carborundum heat exchanger tubes, the bolt presses component includes the seal cartridge assembly being set in turn in the through hole opened up on tube sheet and endoporus locking nut, one end of carborundum heat exchanger tube is connected with end cap after sequentially passing through seal cartridge assembly and endoporus locking nut.
Compared with prior art, the invention has the beneficial effects as follows：
1st, strengthen heat exchanger tube decay resistance using carborundum, extension device service life.
2nd, as the heat exchange efficiency of carborundum is higher, therefore the heat exchange efficiency of whole heat exchanger can be greatly improved, while the volume for reducing heat exchanger diminishes.
3rd, heat exchanger tube covers combination and the single compound mode sealing of screw tightening sealing shroud using V-seal, makes leakage, high temperature high voltage resistant are difficult in heat transfer process.
4, due to being sealed using single heat exchanger tube so that easy to maintenance.

Specific embodiment
Referring to Fig. 1, the present invention relates to a kind of corrosion-resistant carborundum tubular heat exchanger, including housing 1, housing 1 is enamel housing or Stainless Steel Shell, the many thin-walled pressureless sintering carborundum heat exchanger tubes 2 being parallel transversely disposed are provided with the housing 1, the many carborundum heat exchanger tubes 2 are fixed on tube sheet 4 by bolt presses component 3, tube sheet 4 is politef tube sheet or composition metal tube sheet, the tube sheet 4 is arranged between housing 1 and end cap 5, locked by bolt between housing 1 and end cap 5, multiple deflection plates 6 are interspersed with vertically on many carborundum heat exchanger tubes 2, deflection plate 6 is politef deflection plate, the top of the housing 1 is provided with air vent 7 and charging aperture 8, lower section is provided with discharge gate 11, water inlet 9 and outlet 10 are respectively arranged with above the end cap 5.
Referring to Fig. 2-3，Offer on the tube sheet 4 and 2 equal number of carborundum heat exchanger tube and arrangement identical through hole 4.1，The through hole 4.1 is shoulder hole，The bolt presses component 3 includes V-seal set component 3.1 and endoporus locking nut 3.2，Sealing shroud of the V-seal set component 3.1 by multiple two ends for V-type face is constituted，In the middle shoulder hole of through hole 4.1，The outside shoulder hole of through hole 4.1 is screwed hole，The endoporus locking nut 3.2 is located in screwed hole locks V-seal set component 3.1，One end of the carborundum heat exchanger tube 2 sequentially passes through V-seal set component 3.1 and endoporus locking nut 3.2 by the inner side shoulder hole of through hole 4.1，Due to carborundum thermal coefficient of expansion it is little，Carborundum tube bank at relatively high temperatures causes seal failure with shell elongation as the different and caused flexible differences of thermal coefficient of expansion are easily caused connection tube sheet between shell，As the V-seal set component of multiple sealing shrouds composition can provide an elastic cushion space to carborundum heat exchanger tube when expanding with heat and contract with cold，Therefore caused seal failure can be made up because expanding with heat and contract with cold.
