Abstract
The utility model discloses a kind of butane air gas mixed distribution device, its main feature is that：Including air inlet pipe, butane collecting pipe, air collecting pipe, butane distributor pipe, air distribution pipe；Butane distributor pipe and butane collecting pipe vertical connection, air distribution pipe and air collecting pipe vertical connection, butane distributor pipe are arranged in the tube chamber of air distribution pipe, and in air distribution pipe insertion air inlet pipe, air distribution pipe direction of insertion is vertical with air inlet pipe；Exhausting-gas hole is evenly arranged with respectively on butane distributor pipe and air distribution pipe；The lower end of air inlet pipe is connected with static mixing cylinder, and mixed cell is provided with static mixing cylinder；The lower end of static mixing cylinder sets air outlet pipe.The utility model can be such that butane is quickly uniformly mixed with air.
Description
Technical field
The utility model belongs to mixing arrangement technical field, more particularly, to a kind of butane air gas mixed distribution device.
Background technology
Cis-butenedioic anhydride is important Organic Chemicals and fine chemical product, and is only second to the of phthalic anhydride and aceticanhydride in the world
Three big acid anhydrides, its purposes are extremely extensive.Produce cis-butenedioic anhydride using butane and air for raw material, in calandria type fixed bed reactor
Catalyst action issues raw gas phase oxidation, is strong exothermic reaction, and various catalyst are required in process feeds operation
Butane is uniformly mixed with air, avoid, because unstripped gas mixing is uneven, causing part " temperature runaway " and catalyst being caused to damage
Evil, influences reaction conversion ratio, Selectivity of maleic anhydride, yield, catalyst service life and safety in production.
According to traditional experience, gas mixing is passed through two kinds of gases or one of which gas at the same time in a container mostly
Sprayed into a manner of nozzle, free mixing is then carried out by the diffusion motion between gas, this hybrid mode has mixing not
It is enough abundant, uniform, the slow deficiency of mixing velocity.Therefore, it is necessary to improved.
The content of the invention
The purpose of this utility model is in view of the deficiency of the prior art, there is provided a kind of butane air gas mixed distribution
Device, can be such that butane is quickly uniformly mixed with air.
To achieve these goals, technical solution is used by the utility model：A kind of butane air gas mixed distribution device,
Including air inlet pipe, butane collecting pipe, air collecting pipe, butane distributor pipe, air distribution pipe；The butane distributor pipe converges with butane
Flow tube vertical connection, the air distribution pipe and air collecting pipe vertical connection, the butane distributor pipe are arranged on air distribution
In the tube chamber of pipe, in air distribution pipe insertion air inlet pipe, air distribution pipe direction of insertion is vertical with air inlet pipe；The butane distribution
Exhausting-gas hole is evenly arranged with respectively on pipe and air distribution pipe；The lower end of the air inlet pipe is connected with static mixing cylinder, and static state is mixed
Close in cylinder and be provided with mixed cell；The lower end of the static mixing cylinder sets air outlet pipe.
The static mixing cylinder passes through flanged joint.
The mixed cell is orifice plate column.
Exhausting-gas hole on the butane distributor pipe and air distribution pipe is to correspond setting.
With the above structure, the utility model is compared to the prior art advantageously：The utility model passes through
The setting of butane distributor pipe and air distribution pipe, makes butane and air while is discharged by exhausting-gas hole, makees in the diffusion of exhausting-gas hole
Under, butane and air can be mixed uniformly rapidly, and gaseous mixture is further sufficiently mixed by static mixing cylinder again, make butane with
Air mixes evenly, meets production requirement.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the sectional view of C-C in Fig. 1.
Embodiment
As described below is only the preferred embodiment of the utility model, does not therefore limit the protection model of the utility model
Enclose, the utility model is further illustrated with reference to the accompanying drawings and examples.
Embodiment, as shown in Fig. 1 to Fig. 2：A kind of butane air gas mixed distribution device, including air inlet pipe 1, butane collecting pipe 2,
Air collecting pipe 3, butane distributor pipe 4, air distribution pipe 5；The butane distributor pipe 4 and 2 vertical connection of butane collecting pipe, it is described
Air distribution pipe 5 and 3 vertical connection of air collecting pipe, the butane distributor pipe 4 are arranged in the tube chamber of air distribution pipe 5, empty
Qi leel stringing 5 is inserted into air inlet pipe 1, and 5 direction of insertion of air distribution pipe is vertical with air inlet pipe 1；The butane distributor pipe 4 and air
Exhausting-gas hole 6 is evenly arranged with distributor pipe 5 respectively；The lower end of the air inlet pipe 1 is connected with static mixing cylinder 7, static mixing cylinder 7
Inside it is provided with mixed cell 8；The lower end of the static mixing cylinder 7 sets air outlet pipe 9.
Preferably, the static mixing cylinder 7 passes through flanged joint.
Preferably, the mixed cell 8 is orifice plate column.
Preferably, the exhausting-gas hole 6 on the butane distributor pipe 4 and air distribution pipe 5 is to correspond setting.
In use, air A and butane B in proportion enters air point by air collecting pipe 3 and butane collecting pipe 2 respectively
In stringing 5 and butane distributor pipe 4, and discharged by exhausting-gas hole 6, utilize the diffusion of exhausting-gas hole 6 so that butane B and air A
Can rapidly and uniformly it mix, gaseous mixture is entered back into static mixing cylinder 7 and further mixed so that butane B and air A is highly mixed
Close, to reach the demand of safety in production.
