Description

A kind of accurate location and be easy to the anti-dust stratification of side leakage, acidproof dew corrosion heat exchanger
Technical field
The invention belongs to field of heat exchange equipment, be specifically related to a kind of accurate location and be easy to the anti-dust stratification of side leakage, acidproof dew corrosion heat exchanger.
Background technology
On heat power plant boiler or other Industrial Boilers, be provided with the tail gas waste heat recovering system carrying out flue gas waste heat recovery, in tail gas waste heat recovering system, be generally in wet flue gas desulfurization tower porch, flue gas heat-exchange unit is installed, by flue gas heat-exchange unit Mist heat recovering.Flue gas heat-exchange unit, as the nucleus equipment of flue gas waste heat recovery system, decides the performance of residual neat recovering system.Flue gas waste heat recovery significant, this is because the waste heat of flue gas both can be used by flue gas waste heat recovery, can make again the temperature entering fume desulfurizing tower reduce, reduce the evaporation to the moisture in desulfurization sprayed slurry, reduce water consumption.
But, owing to containing the compositions such as sulphur in the fossil fuels such as fire coal, so when burning in heat power plant boiler or other Industrial Boilers, the flue gas containing corrosive gas such as sulfur dioxide, sulfur trioxide, hydrogen chloride, hydrogen fluoride can be produced, especially when exhaust gas temperature is lower than flue gas acid dew point, above corrosive gas can condense concentrated, and produce acid dew, its corrosive power can be stronger.So in order to protect upstream device and flue gas heat-exchange unit not to be corroded; when boiler design; flue-gas temperature (generally between 110-140 DEG C) more than acid dew-point temperature must be ensured; this is the irreducible main cause of exhaust gas temperature; also amount of heat is made by fume emission to air; causing can only recovered flue gas part of waste heat, the significant not shortcoming of economic effect.
Heat exchanger tube in existing flue gas heat-exchange unit is generally adopt common stainless steel metal tube material, and it has some shortcoming following.1, because heat exchanging pipe wall temperature is far below flue gas acid dew point, so acid dew can be produced at the wall of heat exchanger cryogenic tube bundle, cold end corrosion is caused, 2, the flue gas heat-exchange unit of existing common stainless steel metal tube material can not realize the low-temperature heat exchange utilization of flue gas, if namely think as far as possible many recovered flue gas heats, just must reduce flue-gas temperature as far as possible, and meanwhile, the flue gas heat reclaimed is more, cold end corrosion phenomenon on the heat exchanger tube of then stainless steel metal tubing matter will be further serious, the life-span of heat exchanger tube is made to be difficult to ensure, that is, owing to limiting by cold end corrosion, the flue gas heat-exchange unit of existing common stainless steel metal tube material can not by fume afterheat hyperabsorption, must ensure that flue-gas temperature is more than acid dew point, part of waste heat in flue gas can only be absorbed, 3, use in the coal-fired flue gas waiting the boiler of fossil fuel to produce containing a certain amount of flue dust, acid dew contacts with flue dust, scale problems is also inevitable, specifically, be exactly when cigarette temperature drop is low, acid is exposed now, in flue gas, flue dust reveals to combine generate hard scale layer with acid, be attached to heat exchanger tube surface, and tube bundle support plate is waited for death Angle Position, due to the requirement of heat exchange area, tube bank is made to arrange closely, even if adopt the measures such as steam blowing, also be difficult to thoroughly clean out, dirt layer can be more and more thicker, heat exchanger gas collateral resistance is finally made to exceed design load, even cause compressor emergency shutdown.
Heat exchanger tube in existing flue gas heat-exchange unit also has some to have employed the heat exchanger tube be made up of fluoroplastics material completely, the shortcoming of this flue gas heat-exchange unit is that fluorine plastic tube in flue gas heat-exchange unit is for flexible, easily produce under the impact flow of flue gas and shake and deform, not only be very easy to damage, and heat exchange efficiency also can be deteriorated thereupon.
In addition, the fluorine plastic tube structure of existing flue gas heat-exchange unit is reasonable not, fluorine plastic tube to be fixed in locating by bending interting, the bending bending torsion produced affects the installation effectiveness of fluorine plastic tube and reduces service life on the one hand, another is convenient when heat smoke constantly passes through, and trace is strangled in fluoroplastics softening easily generation bending, causes the circulation of fluorine plastic tube inner cooling water not smooth, easily block time serious, reduce heat exchange efficiency.
