And it can also shorten the production cycle, and improve the production energy.
Description
Technical field
The invention belongs to magnesium method sponge production technology, particularly the heat change method and the device of I type or inverted U reduction distillation integrated process titanium sponge production type of furnace inside reactor in the reduction distillation process.
Background technology
The magnesium method is produced the existing I type of titanium sponge and two kinds of type of furnaces of inverted U are used for the reduction distillation produce titanium sponge by combination method, and used reactor is all finished in same process furnace.In order to export the excessive heat that reduction reaction produces, with respect to the position of reaction zone holed refractory brick is set at process furnace, so that ventilate with reaction zone superfluous heat output in the reactor.This radiating mode can only be exported near the heat the reactor wall, and the heat in reactor center zone is difficult for output.Particularly along with the expansion of reactor capacity, the timely and effective output of big calorimetric that above-mentioned ventilation and heat method can not produce the reduction reaction zone causes the titanium sponge that forms in the reduction process to stick together and is difficult to the finishing fragmentation owing to localized hyperthermia makes centre product densification (usually said hard-core); Therefore in the reduction production process, have to the people for slowing down feed rate, and the production cycle is spun out, the corresponding body of heater production capacity that reduced.
Summary of the invention
In order to solve the problems referred to above that prior art exists, a kind of method and apparatus of magnesium method titanium sponge production reactor inner heat exchange is proposed.
A kind of method of magnesium method titanium sponge production reactor inner heat exchange, its special character are with heat exchanger insertion reaction device inside, feed air cooled medium in the heat exchanger, so that the inner superfluous heat of output-response device.
Described heat exchanger is a tube-in-tube heat exchanger.
Described air cooled medium is pressurized air or argon gas.When using pressurized air, by the air compressor air feed; When using argon gas, return air is sent heat exchanger back to by air pump and is recycled after the cooling of tubulation water cooler.
A kind of tube-in-tube heat exchanger that designs for the method for implementing the magnesium method titanium sponge production reactor inner heat exchange, its special character is by pipe in the ring flange installation in outer tube, the upper side of interior pipe is installed into airduct, sight glass is installed at the top of interior pipe, the upper side of outer tube installs back airduct, installs to be used for the assembly flange dish that links to each other with reactor below the junction of outer tube and backwind tube.
In order to make compact construction, the annular intake chute of installation in the outside of the outer tube of tube-in-tube heat exchanger, above the assembly flange dish, the side of annular intake chute is provided with feed port 5, several charge cavitys that communicate with annular intake chute of assembly flange dish upper edge circumference uniform distribution.Titanium tetrachloride disperses to enter in the reactor by intake chute, charge cavity, and evenly reinforced like this, feed rate is controlled.
When implementing this method, at first with heat exchanger insertion reaction device inside, the heat that ventilates then to inside reactor carries out heat exchange.This method can derive the heat of inside reactor effectively, solved from the reactor center position heat that reactor external ventilation radiating mode causes and be difficult for output, the centre product densification because the titanium sponge that localized hyperthermia causes sticks together, the problem that is difficult to the finishing fragmentation; And owing to adopted internal heat exchange measure and dispersed feeding mode, improved feed rate, shortened the production cycle, improved equipment capacity; Owing to shorten reduction cycle, prevent that the pore of titanium sponge in sticking together from further dwindling (cycle is long more, and pore is more little, tend to densification more).Owing to keep the titanium sponge porosity, can shorten the separation cycle of distillation magnesium, magnesium chloride and titanium sponge.
