Description
Technical field
The utility model relates to chemical industry equipment, specifically refers to tower supporting construction in a kind of desulfurizing tower.
Background technology
Denitrating flue gas dust-removal and desulfurizing is the effective measures controlling smoke pollution, wet desulfurizing process is comparatively ripe and conventional technique, " removing the device of SO 2 in waste gas " disclosed in Chinese invention patent ZL200810163800.X, it comprises absorption tower, the side, middle part on absorption tower is provided with waste gas inlet port, gas-liquid distributor is provided with in absorption tower, the top on absorption tower is provided with clean gas floss hole, and be provided with absorbing liquid in the bottom on absorption tower and concentrate zoneofoxidation, concentrated zoneofoxidation is connected with the air hose that the external world is provided with air-blaster by pipeline, gas-liquid distributor is connected through the absorbing liquid of circulating pump with concentrated zoneofoxidation by pipeline, waste gas inlet port is connected with the cooling device in absorption tower, the gas vent of this cooling device is connected with concentrated zoneofoxidation, concentrated zoneofoxidation and absorption tower intracavity inter-connection, and concentrated zoneofoxidation flows to collection place of ammonium sulfate finished product by establishing valvular pipeline through extraction pump.
In this device, concentrated zoneofoxidation is arranged at the bottom of the tower on absorption tower, and be wrapped in outside washing section, corrosivity acid solution is discharged from washing section side exit and is entered concentrated oxidation panel, serious etching problem is all existed to the inside and outside wall of absorber portion and the inwall of concentrated oxidation panel, absorption tower needs to select high-strength corrosion-resisting material to prepare, and manufacturing cost is high; Otherwise the service life on absorption tower is short.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of good corrosion resistance for the present situation of prior art and tower supporting construction in the desulfurizing tower of low cost of manufacture.
The utility model solves the problems of the technologies described above adopted technical scheme: tower supporting construction in this desulfurizing tower, comprise tower, it is characterized in that described upper tower support and connection are on lower tower, the bottom of described upper tower is provided with the first outlet, and the first outlet connects downstream by the first pipeline; Described lower tower is provided with import and the second outlet, and described import connects described upper tower by second pipe, and described second outlet connects downstream by the 3rd pipeline;
Also be provided with ring flat-plate between the outer wall of described upper tower and the inwall of described lower tower, the inner chamber of described lower tower is divided into separate epicoele and cavity of resorption by described ring flat-plate, is equipped with anticorrosive coat on the inwall of described cavity of resorption and on the inwall of described upper tower.
Preferably, peep hole can be provided with on the sidewall of described lower tower corresponding to described epicoele.This peep hole can be used for discharging the confining gas in epicoele on the one hand, and whether the outer surface that can also be used for observing tower on the other hand has the vestige be corroded.
The bottom of preferred described upper tower is pyramidal structure.This structure is convenient to the particulate matter after washing and is precipitated and facilitate discharge.
Connect described in above-mentioned each scheme and be preferably welding.
Compared with prior art, tower supporting construction in desulfurizing tower provided by the utility model, ring flat-plate between Shang Ta and lower tower not only plays reinforcement, reinforces the effect supported, and lower tower is divided into upper and lower two chambeies, the position being not easy to spraying corrosion resistant coating is isolated into epicoele, and epicoele, not as the reative cell of lower tower, greatly strengthen the corrosion resistance of desulfurizing tower, extend the service life of desulfurizing tower, reduce manufacturing cost and use cost; And structure is simple, stressed good.
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1, this desulfurizing tower comprises:
Upper tower 1, the bottom of upper tower 1 is pyramidal structure, and the bottom of upper tower is provided with the first outlet 11, first and exports the sidewall connection upstream device of 11 connection first pipeline 12, first pipelines 12 through lower tower.
Lower tower 2, tower 1 in support and connection, be the barreled structure that upper port is uncovered, the bottom pyramidal end socket of upper tower is welded on the upper surface of lower tower; Lower tower 2 is provided with import 21 and the second outlet 22, and described import 21 connects described upper tower 1 by second pipe 23, and described second outlet 22 connects downstream; .
Ring flat-plate 3, be welded between the outer wall of tower and the inwall of lower tower, the inner chamber of lower tower 2 is divided into separate epicoele 25 and cavity of resorption 26 by ring flat-plate 3; On the sidewall of lower tower, multiple peep hole 27 is provided with corresponding to epicoele 25.
Anticorrosive coat 4, the present embodiment is corrosion-inhibiting coating, also can select other anti-corrosion layer structure as required, on the inwall of cavity of resorption, comprises on tower bottom outer wall, the inwall of lower tower and the lower surface of ring flat-plate; And the inwall of upper tower and the first pipeline is all coated with anticorrosive coat.
In this desulfurizing tower, the operation principle of tower supporting construction is described below:
Slurries in upper tower after process enter downstream from the first outlet via the first pipeline discharge; In upper tower, after partial material extraction, warp enters Xia Ta by second pipe from import 21, discharges, enter downstream after lower tower process from the second outlet via the 3rd pipeline.
