Abstract
The utility model discloses a mixture feeding device of a boiling chlorination furnace. The mixture feeding device comprises a petroleum coke bin, a titanium bin, a mixture bin, a spiral feeding device and a gas injection device, wherein the petroleum coke bin and the titanium bin are communicated with the mixture bin through a discharging hole, and the spiral feeding device is communicated with the discharging hole of the mixture bin. After a metering device respectively meter petroleum coke and titanium, the petroleum coke and the titanium are mixed to enter the mixture bin, the spiral feeding device transports the mixture into a cavity in front of a gas injection hole of the gas injection device, and the gas injection device injects the mixture into the boiling chlorination furnace communicated with the gas injection device through a gas pipeline. Compared with a traditional boiling furnace feeding device, the mixture feeding device of the boiling chlorination furnace has the advantages that the spiral feeding device does not need to go deep into the boiling chlorination furnace, the problem that the spiral feeding device is easily corroded by high-temperature corrosion gases in the boiling chlorination furnace is solved, the production efficiency of the boiling chlorination furnace is increased, and safety accidents and environmental pollution caused by corrosion of the feeding device are avoided.
Description
Technical field
The utility model relates to the compound feeding unit that a kind of chloride process titanium dioxide is produced support equipment, particularly a kind of boiling chloridizing furnace.
Background technology
Fluidizing chlorination in chloride process titanium dioxide production refers to that a refinery coke and titanium material are mixed and made into compound by a certain percentage, joins in boiling chloridizing furnace and under fluidized state, carries out with chlorine the process that chlorination reaction is prepared titanium tetrachloride.Fluidizing chlorination generally carries out under the hot conditions higher than 800 ℃, and boiling chloridizing furnace contains the severe corrosive gases such as chlorine, hydrogenchloride, titanium tetrachloride.
Traditional fluidizing furnace feeding manner is generally that the feed auger by being deep in fluidizing furnace transports material in fluidizing furnace, although can like a cork material dosing be transported in fluidizing furnace, but due to high temperature, the strong corrosive environment in the boiling chloridizing furnace in chloride process titanium dioxide production, the feed auger being deep in fluidizing furnace is easily corroded, and stopping property is poor, easily leak air.
Summary of the invention
The purpose of this utility model is to provide a kind of feeding unit of boiling chloridizing furnace, can overcome the above-mentioned defect of the feeding unit of traditional fluidizing furnace, thereby has solved feeding unit easily by the problem of severe corrosive high-temperature gas corrosion in boiling chloridizing furnace.
The technical scheme that the utility model adopts is:
The compound feeding unit of boiling chloridizing furnace, comprises refinery coke feed bin, titanium feed bin, compound feed bin, screw feeder and gas injection apparatus; Described refinery coke feed bin, titanium feed bin are connected with compound feed bin by discharge port; Described screw feeder is communicated with compound feed bin discharge hole, screw feeder is transported to compound in the cavity before gas injection apparatus gas vent, by gas injection apparatus, by gas piping, compound is ejected in the boiling chloridizing furnace being communicated with it.
Described refinery coke feed bin, titanium feed bin are cone round-ended cylinder structure, and bottom is provided with discharge port, and the titanium material in the refinery coke in refinery coke feed bin, titanium feed bin enters compound feed bin after being arranged on the Weighing device Weighing of discharge port separately.
The angle of described gas injection apparatus gas piping and boiling chloridizing furnace furnace wall is 60 °-90 °.
Compare with traditional fluidizing furnace feeding unit, the utility model does not need spiral that feeding unit is deep in boiling chloridizing furnace, solved screw feeding device easily by the problem of the corrodibility high-temperature gas corrosion in boiling chloridizing furnace, improve the production efficiency of boiling chloridizing furnace, avoided feeding unit to be corroded and the security incident and the environmental pollution that cause.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
Fig. 1 is the structural representation of the hybrid feed mechanism of this boiling chloridizing furnace.
Embodiment
As shown in Figure 1, the feeding unit of this boiling chloridizing furnace comprises refinery coke feed bin 1, titanium feed bin 2, compound feed bin 4, screw feeder 5 and gas injection apparatus 6, and refinery coke feed bin 1, titanium feed bin 2 are connected with compound feed bin 4 by discharge port; Screw feeder 5 is connected with compound feed bin 4 discharge ports, screw feeder 5 is transported to compound in the cavity before gas injection apparatus 6 gas vents, screw feeder 5 seals, screw feeder 5 is not deep in fluidizing chlorination furnace body 7, by gas injection apparatus 6, by gas piping, compound is ejected in the boiling chloridizing furnace 7 being communicated with it.
The gas that gas injection apparatus 6 ejects is for not participating in the reactant gases in boiling chloridizing furnace, and the pressure of ejection gas is greater than the pressure in boiling chloridizing furnace.
The angle of gas injection apparatus 6 gas pipings and boiling chloridizing furnace 7 furnace walls is 60 °-90 °.
Refinery coke feed bin 1 is cone round-ended cylinder structure, and bottom arranges discharge gate, and the refinery coke in refinery coke feed bin enters compound feed bin 4 by discharge gate after Weighing device 3 Weighings.
Titanium feed bin 2 is cone round-ended cylinder structure, and bottom arranges discharge gate, and the titanium material in titanium feed bin enters compound feed bin 4 by discharge gate after Weighing device 3 Weighings.
The working process of the feeding unit of this boiling chloridizing furnace: first dry petroleum coke particles is transported in refinery coke feed bin 1, dry titanium slag is transported in titanium feed bin 2, refinery coke and titanium slag join blending bun 4 by a certain percentage and mix after Weighing device 3 meterings, by screw feeding device 5, mixed compound is delivered in the cavity before gas injection apparatus, what gas injection apparatus ejected is the reactant gases not participating in boiling chloridizing furnace 7, by being 90 ° with fluidizing chlorination furnace wall angle, pipeline is ejected into compound in boiling chloridizing furnace 7 this gas.
