Description
Technical field
This utility model relates to Yellow phosphorus furnace gas disposal field, is specifically related to the heat-insulation system of a kind of Yellow phosphorus furnace air drying cleaner.
Background technology
In the industrial processes of yellow phosphorus, how from the yellow phosphorus furnace gas produced, isolated high-quality, the yellow phosphorus product of high yield are key points of whole production process, and traditional separation method is to utilize wet cleaning technique isolated yellow phosphorus from furnace gas.But, owing to wet cleaning technological process is complicated, separating obtained yellow phosphorus yield is low, purity is low, production process is also accompanied by a large amount of waste residue and waste water produces, production cost crosses the shortcomings such as height, its gradually simple by technique, pollute the dry purification process that yield is high and quality is high little, product and replace.Yellow phosphorus furnace air drying purification process is: the yellow phosphorus furnace gas that will produce in production process, the yellow phosphorus furnace gas generally discharged in electric furnace, the yellow phosphorus furnace gas of cleaning is obtained by dry dust removal equipment after being filtered, again clean yellow phosphorus furnace gas is passed through condensate recovery system, obtain yellow phosphorus solid and tail gas, yellow phosphorus solid can use sale as finished product, the tail gas of gained carries out emptying burning, described dry dust removal equipment at least includes that the filter for filtering high temperature gas, high temperature described here are usually more than 187.5 DEG C.
The temperature keeping the yellow phosphorus furnace gas in the dry dust removal equipment dew point temperature higher than yellow phosphorus furnace gas self is needed in dry purification process, so that the yellow phosphorus in dry dust removal equipment is in gaseous state all the time, improving the response rate of yellow phosphorus in subsequent condensation removal process, described dew point temperature is 160～180 DEG C.The Yellow phosphorus furnace temperature discharged from electric furnace is generally between 120～300 DEG C, but the tolerance discharging furnace gas is not constantly in stable value, even can be close to zero in some time period furnace gas tolerance, owing to dry dust removal equipment surface area is bigger, therefore the Yellow phosphorus furnace temperature being passed in dry dust removal equipment is constantly in fluctuation change, and this fluctuation change procedure is a temperature-fall period, easily cause the Yellow phosphorus furnace temperature dew point temperature less than himself, dew point temperature refers to ambient temperature when yellow phosphorus steam transfers yellow phosphorus liquid to, the yellow phosphorus response rate is caused to decline.For holding furnace temperature higher than himself dew point temperature, it is thus desirable to described dry dust removal equipment is incubated, thermal retardation form directly heats and indirectly heats, the form of directly heating is at filtration outer surface winding electric-heating belt, gas to be carried out heating to prevent cooling, heating mainly arranges chuck at dry dust removal equipment outer surface indirectly, by being passed into chuck after heat transfer medium is electrically heated to uniform temperature, thus reach to be incubated purpose.No matter it is which kind of thermal retardation form above-mentioned all can consume substantial amounts of additional energy source, adds production run cost, cause the wasting of resources.
