Include body, intake pipe and prevent the counterflow unit, the empty cover of body is in in the intake pipe, just the top of intake pipe is located this is internal, prevent that the counterflow unit includes bottom plate, baffle, at least two sets of bracing pieces and a plurality of connecting rod, the inner edge fixed connection of bottom plate is in on the outer wall of intake pipe and outer fringe fixed connection be in on the inner wall of body, the baffle is the bowl form, includes the flow distribution plate and the deflector that fuse, the deflector is located the outer fringe of flow distribution plate, the both ends of bracing piece are located respectively the bottom surface of flow distribution plate and the apical margin of intake pipe make form the reposition of redundant personnel passageway between flow distribution plate and the intake pipe. The utility model discloses reduce the speed of flue gas outdiffusion, the mobile stationarity of reinforcing flue gas improves purifying effect.
Description
Technical field
The utility model relates to chimney field, particularly relates to the improvement of the chimney preventing flue gas from flowing backwards when zinc oxide is smelted.
Background technology
Zinc oxide produces flue gas in Metallurgy Process, to environment.State Bureau discloses a name in 2015.4.29 and is called " zinc oxide smelting flue gas flow backwards chimney ", application number is the utility model patent of " 2014206960819 ", this patent disclosure is a kind of utilizes the baffle plate arranging umbrella cover shape above air inlet pipe, flue gas is mixed along baffle plate with the water in body, and then impel the water in body to be heated to turn to steam, and final and flue gas dual disposal is to outside chimney.In this patent, though adopt water-sealed valve structural principle, prevent flue gas from flowing backwards, but due to baffle plate be umbrella cover shape, when the speed of air inlet pipe discharge flue gas, flue gas is easily gathered in the top of air inlet pipe, even flows backward to air inlet pipe, affects smoke discharging effect.
Utility model content
The utility model, for above problem, provides a kind of design ingenious, strengthens flow of flue gas stationarity, the modified flue gas refluence chimney preventing flue gas from flowing backwards.
The technical solution of the utility model is: comprise body, air inlet pipe and anti-backflow device, and described body empty set is in described air inlet pipe and the top of described air inlet pipe is positioned at described body,
Described anti-backflow device comprises base plate, baffle plate, at least two group support bars and some connecting rods, the Inner edge of described base plate is fixedly connected on the outer wall of described air inlet pipe, and outer rim is fixedly connected on the inwall of described body, described baffle plate is bowl-shape, comprise the flow distribution plate and guide plate that are connected, the outer rim of described flow distribution plate is located at by described guide plate, the two ends of described support bar are located at the bottom surface of described flow distribution plate and the apical margin of air inlet pipe respectively, make to form split channel between described flow distribution plate and air inlet pipe, the two ends of described connecting rod are located on described guide plate and body respectively,
The root edge of described guide plate stretches between described air inlet pipe and body, and described body is provided with water inlet and overfall, described water inlet higher than described air inlet pipe top mouth, described overfall higher than described guide plate root edge and lower than the top mouth of described air inlet pipe.
Described at least two groups, support bar is oblique is arranged symmetrically with.
The inner side of described guide plate root edge is provided with guiding surface.
The utility model is provided with flow distribution plate at the top mouth of air inlet pipe, and flue gas is disperseed to surrounding by flow distribution plate, fully contacts with water, reduce the speed of flue gas to external diffusion, thus strengthen the stationarity of flow of flue gas, prevent flue gas in the top mouth gathering of air inlet pipe, even adverse current, finally improve clean-up effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
In figure, 1 is body, and 11 is water inlets, and 12 is overfalls, and 2 is air inlet pipe, and 3 is anti-backflow devices, and 31 is base plates, and 32 is baffle plates, and 321 is flow distribution plates, and 322 is guide plates, and 3221 is guiding surfaces, and 33 is support bars, and 34 is connecting rods, and 35 is split channels.
Detailed description of the invention
The utility model as shown in Figure 1, comprises body 1, air inlet pipe 2 and anti-backflow device 3, and described body 1 empty set is in described air inlet pipe 2 and the top of described air inlet pipe 2 is positioned at described body 1;
Described anti-backflow device 3 comprises base plate 31, baffle plate 32, at least two group support bars 33 and some connecting rods 34, the Inner edge of described base plate 31 is fixedly connected on the outer wall of described air inlet pipe 2, and outer rim is fixedly connected on the inwall of described body 1, described baffle plate 32 is in bowl-shape, comprise the flow distribution plate 321 and guide plate 322 that are connected, the outer rim of described flow distribution plate 321 is located at by described guide plate 322, the two ends of described support bar 33 are located at the bottom surface of described flow distribution plate 321 and the apical margin of air inlet pipe 2 respectively, make to form split channel 35 between described flow distribution plate 321 and air inlet pipe 2, the two ends of described connecting rod 34 are located on described guide plate 322 and body 1 respectively, for support and connection guide plate 322,
The root edge of described guide plate 322 stretches between described air inlet pipe 2 and body 1, described body 1 is provided with water inlet 11 and overfall 12, described water inlet 11 pushes up mouth higher than described air inlet pipe 2, described overfall 12 higher than described guide plate 322 root edge and lower than the top mouth of described air inlet pipe 2, thus can from water inlet pipe to water filling in body 1, until liquid level is close to the height of overfall 12.
Described at least two groups, support bar 33 is oblique is arranged symmetrically with, and the diagonal namely along described flow distribution plate 321 is arranged, when making described split channel 35 try one's best open, guarantees described baffle plate 32 stress balance.
The inner side of described guide plate 322 root edge is provided with guiding surface 3221, and one is guide effect, and two is reduce obstruction when flue gas distributes from the Inside To Outside of guide plate 322.
