Background technology
The monotubular chimney is because cost outstanding advantage low, simple in structure has been continued to use decades in China, and along with desulphurization system cancellation GGH, smoke moisture strengthens, and the monotubular chimney is because anticorrosion difficulty is limited greatly to adopt, and the industry guide rule recommends to use the sleeve chimney.
Research of technique around the monotubular chimney anticorrosion is being carried out always, has successively adopted many anticorrosion schemes all to fail well to solve anticorrosion problem, and the acid-resistant glaze of employing face brick corrosion-resistant is arranged, and fails basically; Have employing to use the polyurethane foam corrosion-resistant at insulation layer again, because resistant polyurethane is hot poor, shrink reasons such as big, leaking all appears in the chimney after the application.
Summary of the invention
The purpose of this utility model is to provide a kind of monotubular chimney with anticorrosion structure, technical problems such as traditional monotubular chimney anticorrosion technical difficulty is big to solve, functional performance instability.
Monotubular chimney with anticorrosion structure described in the utility model, its structure comprises: the concrete urceolus, be positioned at never solidifying acidproof offset plate or the whole corrosion-proof lining layer of the acidproof spraying of high temperature, be positioned at the foam filled insulation layer on the corrosion-proof lining layer inwall and be positioned at the inner core that the acid of foam filled insulation layer inboard constitutes on the inwall of described concrete urceolus.
Described monotubular chimney with anticorrosion structure, described corrosion-proof lining layer adopt and never solidify acidproof offset plate or the acidproof latex of the spraying anticorrosion high temperature of integral, flexible.
Described monotubular chimney with anticorrosion structure has foam filled insulation layer in the space between corrosion-proof lining layer inwall and acid.
Described monotubular chimney with anticorrosion structure is coated with the high temperature acid proof paint at the acid exposed surface.
The anticorrosion structure that the utility model provides can thoroughly solve monotubular chimney anticorrosion problem, has that cost is low, antiseptic property good and advantage such as long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Concrete structure of the present utility model and making step are as follows:
1) at first is the thick whole corrosion-proof lining of the acidproof latex spray 2mm of SL high temperature that produces with Korea S at the inwall of concrete urceolus, after solidifying fully in 72 hours, forms elasticity high temperature acid-resistant anti-corrosion layer; Or with never solidifying the acid-resistant sheet material stickup.
2) on elasticity high temperature acid-resistant anti-corrosion layer,, build acid by laying bricks or stones, whenever build one meter high inner core brick wall by laying bricks or stones,, finish building by laying bricks or stones of inner core and foam heat-insulation layer synchronously with the acidproof foam foam-in-place of SL200 high temperature filling heat insulating wall according to the project organization of monotubular chimney;
3) with the complete spraying brick of SL200 high temperature acid proof paint surface.
Structure of the present utility model is referring to Fig. 1, and selected concrete position is the bracket position sectional view of chimney.Among Fig. 1, the 1st, high temperature acid proof paint, the 2nd, draining board, the 3rd, the whole corrosion-proof lining layer of the acidproof spraying of high temperature, the 4th, the inner core that acid constitutes, the 5th, the whole corrosion-proof lining layer of the acidproof spraying of high temperature, the 6th, concrete urceolus.
Selection of the present utility model and performance specification:
1) performance of the acidproof latex of SL high temperature and effect
(1) effect of the acidproof latex of SL high temperature
Emulsion layer is an anticorrosive coat, with concrete good adhesion is arranged, and spraying is solidified the back and formed the elastomeric isolation layer, has permanent antiseptic effect under less than 150 ℃ environment temperature, and in the thermal field below 100 ℃, the life-span was above 30 years.
(2) performance of the acidproof latex of SL high temperature
Heat resistance: can long-term work in the dried wet flue gas environment below 150 ℃, the ageing-resistant performance below 100 ℃ is very good
Acid resistance: the sulfuric acid of anti-various concentration, hydrochloric acid, anti-concentration is less than 1% hydrofluoric acid.
Water resistance: water absorption rate is zero
Impervious: impervious pressure is greater than 1Mpa
Elastic deformation: greater than 200%
2) performance of the acidproof foam of SL200 high temperature and effect
(1) effect of the acidproof foam of SL200 high temperature
The filling of foam at first is to play insulation effect, brick lining is because the existence of construction straight joint, high-temperature flue gas can enter insulation layer, the emulsion coating operative temperature is low more, life-span is long more, foam can stop that high-temperature flue gas affacts emulsion coating, be emulsion coating the temperature remains within the normal range work, the anticorrosion life-span was extended to more than 30 years; Next is permeability resistance and superior acid resistance that foam has, has constituted anticorrosive coat again.
(2) performance of the acidproof foam of SL200 high temperature
Heat resistance: can long-term work in the dried wet flue gas environment below 150 ℃, do not have below 150 ℃ and shrink
Acid resistance: the sulfuric acid of anti-various concentration, hydrochloric acid, anti-concentration is less than 2% hydrofluoric acid.
Water resistance: water absorption rate is less than 0.2%
Impervious: impervious pressure is greater than 0.2Mpa
3) performance of SL200 high temperature acid proof paint and effect
(1) effect of SL200 high temperature acid proof paint
The effect of SL200 high temperature acid proof paint is that sealing is anticorrosion, isolates the corrosion thing and permeates in acid.The acid resistant adhesive mortar of the usefulness of laying bricks is a sodium silicate mastic, poor water resistance, and promptly dewatering state forms down intensity, plays cementation, and moist water state lower part or lose intensity fully causes the inner core brick construction to damage; Acid is a permeable mass, and the wet flue gas of operation under positive pressure can pass acid and penetrate into brickwork joint clay and insulation layer in the chimney, forms corrosive environment.After the acid surface is coated with the high temperature acid proof paint, forms and seal anticorrosive coat together.
(2) performance of high temperature acid proof paint
Temperature tolerance: long-term work below 160 ℃
Acid resistance: the sulfuric acid of anti-various concentration, hydrochloric acid, anti-concentration is less than 5% hydrofluoric acid.
Water resistance: water absorption rate is less than 0.2%
Impervious: impervious pressure is greater than 0.5Mpa
Described inner core acid adopts standard refractory brick, and from moving the chimney more than 20 years, refractory fireclay block is corrosion-resistant best.Adopt the extraordinary acid resistant adhesive mortar of the SL300 effect of laying bricks best, it is to consider that cost allows.The construction environment temperature should be controlled at more than 10 ℃.
