3With the high temperature rapids of the pyrolytic semlting relieving haperacidity gas of sulfuric acid mist and flue gas desulfurization purifying and cooling towards sluicing pipe and preparation process thereof.
(2) background technique:
At present, the domestic SO that is used for
2, SO
3Mainly contain following two classes with the device of sulfuric acid mist pyrolytic semlting relieving haperacidity gas and flue gas desulfurization purifying and cooling, the one, with the cooling tower of carbon steel, polyolefin plastics lining or other brick plates, the 2nd, make the pipe fitting washing machine with the Hastelloy that antiseptic property is good; Adopt the generally preposition dust precipitator of palpus of cooling tower, investment cost is big, and antiseptic property is poor, and working life is 4-5 only; Adopt the Hastelloy pipe of import to make pipe fitting, cost an arm and a leg, difficulty of processing is big, the cost height.
(3) summary of the invention:
Purpose of the present invention proposes a kind of high temperature resistant, anti-various dielectric corrosions exactly, and long service life is cancelled preposition electrostatic precipitator and made the lower high temperature rapids of overall cost towards sluicing pipe, simultaneously, provides its preparation process.
High temperature rapids of the present invention is towards sluicing pipe, comprise the bypass channel that is arranged on the sluicing pipe top, high temperature processing section that is connected with bypass channel and the middle temperature processing section that is connected high temperature processing section rear portion, the sluicing pipe outer surface is twined by continuous glass fibre reinforced plastics, and described sluicing pipe tube wall constitutes by three layers of from the inside to the outside carburization zone, graphite fiberglass layer, refractory layers are compound respectively.
The carburization zone of described formation tube wall is made up of 1-2 weight portion carbon dust, 3-4 weight portion carbon fiber, 1-2 weight portion binder, 0.05-0.1 weight portion curing agent; The graphite fiberglass layer is made up of 3-4 weight portion plumbago, 5-6 weight portion glass fibre, 2-3 weight portion binder, 0.1-0.2 weight portion curing agent; Refractory layer is made up of 5-6 weight portion glass fibre, 1-2 weight portion carbon dust, 1.5-2.5 weight portion binder, 0.05-0.15 weight portion curing agent.
Preparation high temperature rapids comprises the steps: that towards the technology of sluicing pipe a. gets the raw materials ready and stirs by the composition and the consumption of described carburization zone, graphite fiber layer, refractory layer respectively, accumulates on the mould from the inside to the outside; B. when every layer of curing degree reaches 70-80%, be warming up to 300-800 ℃ of carbonization 50-70 minute; After reducing to room temperature, the carbonization that heats up again, three times repeatedly; C. fw frp outside refractory layer, and bypass channel is set at the top, get final product.
The pipe fitting of made through 500 ℃ of high-temperature bakings 30 minutes, was placed normal temperature liquid 10 minutes immediately, and 5 times so repeatedly, pipe fitting is excellent, no stratification, internal layer intensity height.
400 ℃ high-temperature flue gas is cooled to below 110 ℃ after this pipe fitting high temperature section (about 8m is long) and contrary spray acid solution are carried out mass-and heat-transfer, enters middle-temperature section again and reduces to about 70 ℃, can directly enter in the storage container.
The present invention compared with prior art has the following advantages:
1. can tolerate 350 ℃ and contain SO
2, SO
3, impurity such as As, F, Cl and acid mist the corrosion of relieving haperacidity flue gas, long service life;
2. can replace needs the Hastelloy of import pipe, and compared with similar products, price is lower;
3. make once-combined moulding, technology is simple, and the body good integrity of producing has overcome poor, the easy to leak burn into short defective in working life of pipe fitting bonding strength that other technologies, other materials are produced.
(4) description of drawings:
Fig. 1 is an overall structure schematic representation of the present invention;
Fig. 2 is the local structure for amplifying schematic representation of tube wall composite bed among the present invention.
The 1-body, 2-bypass channel, 3-high temperature processing section, warm processing section among the 4-, 5-glass fibre reinforced plastics outer wall, 6-carburization zone, 7-graphite fiberglass layer, 8-refractory layer, 9-sour water inlet.
