Abstract
The utility model relates to a tower base wet chimney used in low temperature discharge after gas desulphurization, the tower base wet chimney comprises a desulphurization tower to support the chimney body, a desulphurization tower and a cone connected with the chimney, an erosion resistant chimney, a chimney reinforcement, and a chimney checking and sampling hole. The tower base wet chimney can be used to satisfy the function of discharging the gas after desulphurization, at the same time, is provided with effects of gas discharging resistance reduction (energy saving), chimney building cost saving, and chimney layout land occupation saving, is built in cooperation with engineering projects such as middle and small scale power station gas wet method desulphurization, melting factory sintering gas wet method desulphurization, and is provided with good technical economic benefits.
Description
Technical field
The utility model relates to a kind of wet chimney of column foot that discharged at lower temperature is used after the flue gas desulfurization that is used for.
Background technology
Contain a large amount of SO in middle-size and small-size generating plant flue gas or the smelting factory sinter fume
2, must supporting desulfurizer protection environment.The wet desulphurization technology is effective flue gas desulfurization technique, and its desulfuration efficiency height is widely used.
In present middle-size and small-size generating plant flue gas or the smelting factory sintering smoke wet method sulphur technology, mainly adopt desulfurizing tower, air-introduced machine and chimney to be connected in series in proper order, and all the basis is set independently, be arranged on ground or the platform.Because temperature reduced after desulfurizing tower exported higher and flue gas desulfurization, so need induced draft blower withdraws or be connected to anticorrosion smoke stack emission by overhead flue.The problem that exists comprises: connecting pipe is long, the fume emission flow path resistance is big; Connection flue and chimney etc. are basic and the body construction materials are many; Each equipment must take position, and land used is many, especially installs flue gas desulphurization system additional for some existing power stations or sintering plant, and the transformation project place is limited, difficult arrangement.
Summary of the invention
At the problem of above-mentioned existence, the purpose of this utility model is to be wet fuel gas desulfurizing technology, supporting a kind of have cut down the consumption of energy, the wet chimney of column foots such as economical with materials and saving occupation of land, its technical solution is:
Anticorrosion chimney is fixedly connected on the exit of desulfurizing tower by the cone that has the arc linkage section, highly locates to be provided with flue gas at anticorrosion chimney 1/3rd and detects thief hole, at anticorrosion chimney vertical stratification arranged outside horizontal stiffener; The arc linkage section outside in cone is provided with T shape reinforcement; The cone that connects desulfurizing tower and anticorrosion chimney, the import cross sectional shape of the corresponding anticorrosion chimney of upper/lower terminal end surface shape difference and the outlet shape of desulfurizing tower.
Owing to adopted above technical scheme, the wet chimney of column foot utilizes the basis of smoke-gas wet desulfurization tower body as its wet flue gas blowdown stack, the supporting wet flue gas blowdown stack and the supporting weight of attachment and relevant load thereof; Utilize a cone to connect desulfurizing tower and wet chimney simultaneously, cone is according to desulfurizing tower smoke outlet shape and stack cross section shaped design, and two ends all have the arc transition section and connect, and evenly dredges flue gas and even distributed load; The stack cross section can be circular (comprising ellipse) or rectangle (comprising square), and its outer level hoop dress reinforcement is gained in strength; Chimney body adopts anticorrosion structure, can be that steel construction inside lining anti-corrosive layer is coated with corrosion resistant coating outward, or glass fibre reinforced plastic structure integral body is anticorrosion, adapts to the wet flue gas requirement for anticorrosion; Highly locate the online detection thief hole of flue gas is set at anticorrosion chimney 1/3rd, and anticorrosion with chimney body integral body.
The technical solution of the utility model, to the key equipment desulfurizing tower and the reasonable winding of chimney of wet fuel gas desulfurizing technology, system is simple, and flue gas resistance is little, has energy-saving effect; It is few to connect flue, and material usage is saved; Especially the wet chimney of column foot is that the main facilities combination is arranged, effectively saves and takes up an area of arrangement convenience.
Description of drawings
Accompanying drawing is the wet chimney structure schematic diagram of column foot.
Specific embodiments
Below in conjunction with accompanying drawing the utility model is described in further detail.
See accompanying drawing.
The wet chimney of column foot comprises smoke-gas wet desulfurization tower 1, cone 2, and flue gas detects thief hole 3, anticorrosion chimney 4, chimney reinforcement 5, concrete structure is:
One. wet chimney integrated desulfurizing tower of column foot and wet chimney are in one, and anticorrosion chimney 4 is based on desulfurizing tower 1.Anticorrosion chimney 4 is connected with desulfurizing tower 1 by cone 2, and utilizes the weight of desulfurizing tower 1 supporting and possible various additional loads.
Two, the cone 2 of the wet chimney of column foot, the two ends shape is consistent with the import cross sectional shape of the outlet of desulfurizing tower 1 and anticorrosion chimney 4 respectively, and all adopts excessive section of continuous arc at the two ends of cone 2 sidewall, eliminates the angle and connects the stress that exists and concentrate, evenly dredge fume emission, uniform stress load.
Three. highly locate to be provided with flue gas at anticorrosion chimney 1/4th three and detect thief hole 3.
Four, the whole anticorrosion structure that adopts of the wet chimney of column foot adapts to the wet flue gas emission request.Cone 2, flue gas detect thief hole 3 and anticorrosion chimney 4 bodies, all adopt anticorrosion structure, can be that steel construction inside lining anti-corrosive layer is coated with corrosion resistant coating outward, also can be glass fibre reinforced plastic structures.
Five. anticorrosion chimney 4 cross sections can be circular (comprising ellipse) or rectangles (comprising square); Anticorrosion chimney 4 body constructions are provided with horizontal stiffener 5 outward.
As required, can also overhaul with platform and ladder in the outer setting of desulfurizing tower 1, cone 2 and anticorrosion chimney 4, and necessary lightning protection facility and navigation mark facility.
