Embodiment
The present invention is the method for the anti-calcium of chlorination furnace roof during a kind of titanium tetrachloride is produced, magnesium, iron adhesion obstruction, the method can effectively solve titanium tetrachloride produce in the easy blocked problem of chlorination furnace furnace roof outlet conduit, for production, the service efficiency of raising chlorination furnace have been established primary condition.
It is to be noted: chlorination furnace roof disposes outlet conduit, described outlet conduit is discharged and is contained calcium, magnesium, the formed chloride impurity gas of iron.
The present invention disposes smoke evacuation and preventing clogging up device on described outlet conduit, this device comprises four-way pipe 1, inverted cone-shaped dust collection cover 2, pressure equalizing pipe 3, the first gas pipeline 4, the second gas pipeline 5, backup line and relevant gate valve, although these configurations are common, but act on chlorination furnace and can prevent described calcium, magnesium, iron from being adhered to and produce the latch up phenomenon unfavorable problem that causes discharging fume, its effect is unforeseen.
By the following examples, can explain in more detail the present invention, the present invention is not limited to the following examples, discloses object of the present invention and is intended to protect all changes and improvements in the scope of the invention.
In conjunction with Fig. 1, first described outlet conduit is connected with the second gas pipeline 5, the second gas pipeline 5 is by the lower end flange connect of flange and four-way pipe 1, the upper flanges of four-way pipe 1 connects with inverted cone-shaped dust collection cover 2 by upper end gate valve, the left end of four-way pipe 1 or right-hand member flange connect with the first gas pipeline 4 by the first gate valve, between inverted cone-shaped dust collection cover 2 and the first gas pipeline 4, are connected with pressure equalizing pipe 3.
Although Fig. 1 does not directly provide described upper end gate valve, described the first gate valve, described side gate valve and described backup line, but do not affect the existence of these configurations, the right-hand member of four-way pipe 1 or left end are implemented close or open and can connect backup line by side gate valve, between inverted cone-shaped dust collection cover 2 and described backup line, are also connected with pressure equalizing pipe 3.
The caliber of caliber < first gas pipeline 4 of pressure equalizing pipe 3.
The caliber of caliber≤the second gas pipeline 5 of the first gas pipeline 4, the caliber of caliber≤the first gas pipeline 4 of described backup line.
The external size of described upper end gate valve or equate with the external size of described the first gate valve, or unequal.
The external size of described the first gate valve or equate with the external size of described side gate valve, or unequal.
The present invention advises that the external size of described upper end gate valve, described the first gate valve, described side gate valve equates, because the described upper end gate valve of same model, described the first gate valve, described side gate valve have better interchangeability, above-mentioned gate valve or rotary valve or plate valve are advised in the Fast Installation of being more convenient for and dismounting simultaneously.
When above-mentioned smoke evacuation and preventing clogging up device work, described upper end gate valve and described the first gate valve all in opening working order described side gate valve in closing working order, described chloride impurity gas enters in four-way pipe 1 by the second gas pipeline 5, because making the pressure in inverted cone-shaped dust collection cover 2 and the first gas pipeline 4, the configuration of pressure equalizing pipe 3 equates, a large amount of described chloride impurity gases directly enter in vertically disposed inverted cone-shaped dust collection cover 2 along with the effect of its rising inertia, a small amount of described chloride impurity gas can enter in horizontally disposed the first gas pipeline 4 and directly be discharged, enter the calcium in the interior described chloride impurity gas of inverted cone-shaped dust collection cover 2, magnesium, iron is adhered on the inwall of dust collection cover 2 under the effect of gravity, through gathering dust, the described chloride impurity gas of processing can enter in the first gas pipeline 4 along pressure equalizing pipe 3, enter the calcium in the interior described chloride impurity gas of the first gas pipeline 4, magnesium, iron also can partly be adhered on the inwall of the first gas pipeline 4 under the effect of gravity.
Because the spatial content in inverted cone-shaped dust collection cover 2 is larger, when the described calcium, magnesium, the iron that are adhered on inverted cone-shaped dust collection cover 2 inwalls are more, close described upper end gate valve and pull down dust collection cover, after inverted cone-shaped dust collection cover 2 is cleared up, connect with described upper end gate valve again and make described upper end gate valve can recover the effect of gathering dust of inverted cone-shaped dust collection cover 2 in described unlatching working order.
When the described calcium, magnesium, the iron that are adhered on the inwall of the first gas pipeline 4 are more, first on described side gate valve, connect clean described backup line, and then close described the first gate valve and pull down the first gas pipeline 4, through to connecting with described the first gate valve again and make described the first gate valve can recover the smoke evacuation effect of the first gas pipeline 4 in described unlatching working order after the first gas pipeline 4 cleaning, close again afterwards described side gate valve and pull down described backup line and to its cleaning.
Cleaning inverted cone-shaped dust collection cover 2 or the process of cleaning the first gas pipeline 4 do not affect the described chloride impurity gas of the second gas pipeline 5 normal discharge, and then guaranteed during titanium tetrachloride is produced that outlet conduit is normal described in chlorination furnace roof and discharged described chloride impurity gas, owing to producing without adhering to latch up phenomenon in inverted cone-shaped dust collection cover 2, the first gas pipeline 4 and the described backup line cleared up in time, thus titanium tetrachloride produce in chlorination furnace roof also can not adhered to by described calcium, magnesium, iron and produce latch up phenomenon.
By above-mentioned, can obviously find out: the invention solves on the inwall that described calcium, magnesium, iron often sticks to described outlet conduit and cause chlorination furnace to stop the problem of producing, simple, practical feature that method has, for good technical qualification have been created in the normal production of titanium tetrachloride, also reduced the stopping production number of times causing due to plugging, improved titanium tetrachloride turnout, according to measuring and calculating: production can increase by 1,008 ten thousand yuan of profits more continuously.
