Abstract
The invention discloses a kind of yellow phosphorus furnace slag wind to quench method of cooling, comprise the steps: that phosphorus stove high temperature furnace slag is out first through once cooling, outlet wind-warm syndrome controls at 600-900 DEG C, and cooling air adopts the two-step cooling wind of cooling twice, and then slag enters cooling twice and cools further; When entering cooling twice, material is half melt, temperature of charge about 800-1100 DEG C, cooling twice divides two sections to cool, the temperature of one-step cooling wind controls at 600-900 DEG C, boiler for producing steam is sent to together with the hot blast once cooling out, two-step cooling wind-warm syndrome controls at 200-400 DEG C, and cooling twice outlet mass temperatures is 65-100 DEG C, goes to downstream through cooled slag.Present invention saves water resources.Energy consumption is relative with cost of labor to be reduced, and greatly reduces the production cost of yellow phosphorus.
Description
Technical field
The invention belongs to chemical technology field, be specifically related to a kind of yellow phosphorus furnace slag wind and quench method of cooling.
Background technology
Along with the scarcity of resource and the progress of technology, the utilization of the slag that phosphorus production produces more and more receives publicity, and is mainly used in building materials at present, the industries such as agrochemical.After the high-temperature molten-state slag produced in phosphorus production process discharges phosphorus stove, adopt the processing mode of water quenching technology at present, namely by slag chilling.High temperature furnace slag bursts apart because of the cause of internal stress, becomes small-particle bits and disperses inside slag bath, so that the shipment of slag, store up process.
But slag can produce a large amount of water vapour also when Water Quenching, bring certain impact to the equipment of yellow phosphorus unit, Architecture and Environment, the heat energy simultaneously inside slag is not used.Water of productive use amount is large, and slag needs drying and processing in later use process, energy consumption and cost of labor higher.Water Quenching Slag needs to grab slag driving and grabs hopper filter part water, and then have bad luck downstream unit material storage yard with automobile, transfer cost is higher.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming and the one provided has saved water resources.Energy consumption is relative with cost of labor to be reduced, and the yellow phosphorus furnace slag wind greatly reducing the production cost of yellow phosphorus is quenched method of cooling.
A kind of yellow phosphorus furnace slag wind of the present invention is quenched method of cooling, comprises the steps:
(1) phosphorus stove high temperature furnace slag is out first through once cooling, and outlet wind-warm syndrome controls at 600-900 DEG C, and cooling air adopts the two-step cooling wind of cooling twice, and then slag enters cooling twice and cools further;
(2) when entering cooling twice, material is half melt, temperature of charge about 800-1100 DEG C, cooling twice divides two sections to cool, the temperature of one-step cooling wind controls at 600-900 DEG C, boiler for producing steam is sent to together with the hot blast once cooling out, two-step cooling wind-warm syndrome controls at 200-400 DEG C, and cooling twice outlet mass temperatures is 65-100 DEG C, goes to downstream through cooled slag.
Above-mentioned a kind of yellow phosphorus furnace slag wind is quenched method of cooling, wherein: the hot blast that two-step cooling produces can be other device with the hot blast that one-step cooling produces and provides heat energy or for generating electricity.
Above-mentioned a kind of yellow phosphorus furnace slag wind is quenched method of cooling, wherein: slag goes to downstream to be send to production super-fine powder.
The present invention compared with prior art, there is obvious beneficial effect, as can be known from the above technical solutions: the present invention makes the heat energy of high temperature furnace slag be fully used by the heat exchange of cooling twice, change the problem of a large amount of moisture contamination produced in the shrend process of slag simultaneously, site environment improves, water of productive use reduces in a large number, has saved water resources.Slag no longer needs drying and processing in later use process, and production station reduces relatively, and energy consumption is relative with cost of labor to be reduced, and production cost declines, thus greatly reduces the production cost of yellow phosphorus, improves the competitive power that yellow phosphorus is in the field of business.Cooled slag can be directly used in Downstream Products, does not need dry consumption heat energy further; Wind slag of quenching directly can adopt Belt Conveying, thus effectively reduces cost of wheeling.
Below by way of embodiment, further illustrate beneficial effect of the present invention.
