Description
Technical field
This utility model relates to corrosion-resistant structure, a kind of corrosion-resistant structure for heat exchanger.
Background technology
At present, in the flue gas waste heat recovery system of petrochemical industry and tubular heater, and in Industrial Boiler or station boiler, generally there is air preheater low-temperature dew point corrosion phenomenon: when exhaust gas temperature is relatively low (e.g., less than 160 DEG C), the tube wall temperature being positioned at exhanst gas outlet is easy to the acid dew point less than flue gas, cause serious low-temperature flue gas acid dew piont corrosion, the equipment replacement caused because of cold end corrosion and gambling ash every year and the direct cost of stopping production deashing account for the 4% ~ 5% of operating cost, currently, a lot of users are in order to avoid cold end corrosion, do not stint improve boiler exhaust gas temperature, reduce the thermal efficiency of boiler, according to measuring and calculating, exhaust gas temperature often improves 10 DEG C, boiler thermal output will decline about 1%, thus cause substantial amounts of energy loss.nullSolution is usually and uses enamel technology at fume side tube surface at present，Use between heat pipe with tube sheet and weld、Or teflin ring seals，During owing to using welding manner to seal，Enamel is unfavorable for welding，Welding position does not plate enamel，This part is caused to have corrosion phenomenon in running，Simultaneously in running，Find that the aperture plate with smoke contacts also has corrosion phenomenon，After aperture plate surface use acid resistant adhesive mortar pour，Reduce low-temperature dew point corrosion，But，Due to acid resistant adhesive mortar short texture，Porosity is big，Rough surface，The finest and close，Thus it is doomed that it is impervious poor，Construction technology stress during cure irregular crackle of excessive generation because of this thick slurry film forming，After clay layer absorbs water，Owing to acid resistant adhesive mortar has big difference with the basal plane coefficient of expansion，Under malleation in air preheater and high temperature action，Crackle can be expanded further，Even ftracture，And then may peel off with basal plane，Therefore，Acidic liquid in flue gas also can directly permeate and touch air preheater aperture plate，So that anticorrosion lost efficacy.
Utility model content
Technical problem to be solved in the utility model is, for the shortcoming of above prior art, propose a kind of corrosion-resistant structure for heat exchanger, be not only simple in structure, easy to operate, anticorrosion effect is good, and anti-corrosion layer structural strength is high, good seal performance, service life is long, low cost, safe and reliable, economize on resources.
In order to solve above-mentioned technical problem, the technical solution of the utility model is achieved in the following ways: a kind of corrosion-resistant structure for heat exchanger, including horizontally disposed two section bar supports and heat pipe, between two section bar supports, level is provided with supporting plate, a heat pipe the most vertically it is provided with on described supporting plate surface, described heat pipe runs through supporting plate, it is provided with anti-corrosion layer in described supporting plate upper surface, described anti-corrosion layer is made up of basalt fibre skeleton and corrosion-resistant clay, described basalt fibre skeleton is coated in corrosion-resistant clay formation anti-corrosion layer, and be coated in anti-corrosion layer in the middle part of described heat pipe.
So, pass through the technical solution of the utility model, corrosion-resistant clay and basalt fibre skeleton is used to form anti-corrosion layer, it is not only simple in structure, bulk strength is high, basalt fibre is a kind of novel inorganic environment-friendly and green high performance fibre material, and the basalt building stones that it is made up of oxides such as silicon dioxide, aluminium oxide, calcium oxide, ferrum oxide and titanium dioxide are after high-temperature fusion, by bushing Defect；Basalt continuous fiber not only good stability, also has electrical insulating property, anticorrosive, flame resistant, the multiple excellent properties such as high temperature resistant；Solving existing anti-corrosion layer short texture, porosity is big, rough surface, unsound problem.
The technical scheme that this utility model limits further is:
