It arranges a lower discharge outlet at the expansion valve whose lower edge is connected with a discharge pipe; the bottom of discharge pipe is connect to a automatic discharge valve whose valve body has a water inlet; the water outlet at the lower part of said valve has a block; the valve body has a float inside it while the top of float has a transmission device; and the automatic discharge valve is connected to the limestone pulp bank via the connection pipe. The invention can solve the problems that automatically discharge the water accumulated at the expansion valve to reduce the corrosion on the smoke channel, prolong the service life of expansion and confirm the normal operation of smoke desulfuration system, while it can apply the wet smoke desulfuration process.
Description
(1) technical field
The present invention relates to a kind of drainage arrangement and method thereof of flue expansion joint.
(2) background technology
In the wet fuel gas desulfurizing technology of thermal power plant, former flue gas behind the lime stone slurry washing desulphurization, becomes clean flue gas in the absorption tower, enter clean flue.Clean flue gas has carried a large amount of droplets, and is saturation state, and the absorption tower demisting device can not be with the complete Ex-all of the droplet in the flue gas, very easily separates out moisture when clean flue gas is lowered the temperature in clean flue, and general flue bottom is all designed gradient, and moisture can be discharged automatically.But the expansion joint of clean flue has a groove, and moisture is assembled in this groove and can't be discharged.Because the moisture in the flue has dissolved acid and multiple compound, as easy as rolling off a log corrosion flue, and at north of china in winter, can freeze under the shutdown situation, shorten the life-span of expansion joint.In this case, it is imperative to develop a kind of self-draining arrangement.
(3) summary of the invention
The objective of the invention is to design a kind of Flue Expansion Joint Automatic Bailer And Method, solve the automatic problem of discharging of ponding at flue expansion joint place.
Technical scheme of the present invention:
This flue expansion joint self-draining arrangement, tube wall at clean flue disconnects, gap connects expansion joint, it is characterized in that: the covering both sides of expansion joint are clipped between expansion joint framework and the pressing plate by the gap that is bolted to clean flue tube wall, on expansion joint, establish a low level outlet, water pipe runs in low level discharge outlet lower edge, the drainpipe bottom connects automatic drain valve, on the valve body of above-mentioned automatic drain valve water inlet is arranged, the discharge outlet place of valve body lower portion is connected with to press and blocks up, float is arranged in the valve body, and float is equipped with link gear on the top, and automatic drain valve is communicated with the lime stone slurry case through tube connector.
Be connected hose connector between above-mentioned low level discharge outlet and the drainpipe.
Above-mentioned link gear mainly comprises interlock valve plate, valve rod, is enclosed within the holddown spring on the valve rod, the sealing gland and the housing pin at valve rod top.
Above-mentioned float is ball float or floating drum.
This flue expansion joint self-draining method is characterized in that: adopt any described flue expansion joint self-draining arrangement of claim 1-4, and following steps are arranged:
(1), water-filling: float is positioned at the bottom of automatic drain valve body, pushes down that the pressure at discharge outlet place is stifled blocks discharge outlet, and the water inlet of automatic drain valve body is opened simultaneously, hydrophobicly enters the automatic drain valve body from water inlet;
(2), beginning force feed: water level raises in the automatic drain valve body, and float raises with liquid level, and float roof pressure link gear drives valve plate water inlet is closed, and the pressure at discharge outlet place is stifled unclamps, and discharge outlet is opened;
(3), finish force feed: with hydrophobic discharge, float descends, and the pressure at extrusion drainage mouth place is stifled, closes discharge outlet;
(4), water-filling again, move in circles.
Operation principle of the present invention: utilize float floating or descending in valve body to drive the link gear action, make valve body keep certain liquid level by the flow of regulating the turnover valve body, when liquid level was lower than setting, float descended water inlet is opened, and liquid level increases in the liquid inflow valve body.When liquid level rose to the regulation liquid level, float floated, and water inlet is closed, and liquid stops to flow into, and discharge outlet is opened, hydrophobic discharge.
The present invention has following advantage: clean flue is connected with expansion joint firmly, guarantees that by automatic drain valve draining is unobstructed.Water gathers certain liquid level in valve, and water is discharged automatically.Whenever having guaranteed like this in the expansion joint not can liquid collecting, has reduced the corrosion of hydrops to flue, has prolonged the expansion joint life-span, has ensured the normal operation of flue gas desulphurization system.Self-draining arrangement of the present invention adopts the anticorrosive of ability flue gas waste liquid corrosion, can be widely used in the clean flue expansion joint in the wet fuel gas desulfurizing technology.
