Background technology
At present China is sure to occupy the first in the world great Mei producing country and exporting country, and the production of magnesium metal mainly contains two kinds of thermal reduction and electrolysis, but most enterprises of China are used thermal reduction legal system magnesium technique.Due to the magnesium-reduced slag of 6 tons of 1 ton of magnesium average generation of the every production of method for smelting magnesium by hot, and the temperature that slag leaves reduction tank is the high temperature of 1200 DEG C, contained a large amount of heat energy.But be limited to existing technology, high temperature furnace slag is directly transported to be put plant area aside as useless and piles up and be difficult to effective utilization, and the UTILIZATION OF VESIDUAL HEAT IN that high temperature furnace slag is contained more rarely has research application.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the high temperature waste residue that provides a kind of structure uniqueness, utilize method for smelting magnesium by hot to produce is heated as high-temperature water as energy source cooling water, realize the recycling of energy, save a large amount of fossil energies, reduced the magnesium smelting reducing slag waste heat boiler of the production cost of magnesium metal.
The present invention realizes in the following way:
A kind of magnesium smelting reducing slag waste heat boiler, it comprises outer cylinder body, inner barrel, the end socket at outer cylinder body two ends, the shrouding of pulling limit tube sheet and the other end of inner barrel one end, it is characterized in that: open on an above-mentioned side seal head cooling water inlet, heat-exchanging tube bundle is horizontally fixed on above-mentioned inner barrel the inside by shrouding and gripper shoe, high temperature waste residue entrance and low temperature waste residue outlet disposed at equal distance are in top and the bottom of outer cylinder body, exhaust outlet is equipped with on outer cylinder body top from left to right successively, pressure gauge connection, relief valve connection, hanger, high-temperature water outlet, outer cylinder body bottom is equipped with sewage draining exit and saddle from right to left successively,
In described gripper shoe, be fixed with vertical clapboard and horizontal baffle;
On the end socket of the both sides of described outer cylinder body, be provided with population, population is provided with hand hole, and steam discharge base is housed on described exhaust outlet;
Distance between described heat-exchanging tube bundle can make high temperature pelletizing pass through smoothly.
The present invention has following effect:
1) structure uniqueness: it comprises outer cylinder body waste heat boiler provided by the invention, inner barrel, the end socket at outer cylinder body two ends, the shrouding of pulling limit tube sheet and the other end of inner barrel one end, it is characterized in that: open on an above-mentioned side seal head cooling water inlet, heat-exchanging tube bundle is horizontally fixed on above-mentioned inner barrel the inside by shrouding and gripper shoe, high temperature waste residue entrance and low temperature waste residue outlet disposed at equal distance are in top and the bottom of outer cylinder body, exhaust outlet is equipped with on outer cylinder body top from left to right successively, pressure gauge connection, relief valve connection, hanger, high-temperature water outlet, outer cylinder body bottom is equipped with sewage draining exit and saddle from right to left successively, heat exchanger tube is horizontally fixed on inner barrel the inside by the shrouding in the end socket of waste heat boiler two ends and gripper shoe, and the distance between tube bank can make high temperature pelletizing pass through smoothly, cooling water is exported for user by high-temperature water outlet after being heated as high-temperature water by high temperature waste residue, high temperature waste residue entrance and low temperature waste residue outlet disposed at equal distance are in waste heat boiler top and bottom, and entering and discharging of waste residue is convenient in its position one by one correspondence.
2) the high temperature waste residue that utilizes method for smelting magnesium by hot to produce is heated as high-temperature water as energy source cooling water, realize the recycling of energy: waste heat boiler low-temperature cooling water provided by the invention is flowed in waste heat boiler one side seal head by cooling water inlet, heating is proceeded in the gap that the heating of carrying out four backhauls by heat exchanger tube flows between inner barrel and outer cylinder body afterwards, and final cooling water is heated to be high-temperature steam and is exported by steam (vapor) outlet; High temperature waste residue is put into successively waste heat boiler by high temperature waste residue entrance by certain time interval cooling water is heated, and completes to open the outlet of low temperature waste residue after the heat exchange of one-period and discharge the waste residue after being cooled.The Conversion of Energy that the high temperature waste residue that it can effectively produce magnesium smelting contains is steam, for other equipment provide kinetic energy.
3) improve workman's work situation, reduce workman's labour intensity: be down to 200 DEG C because the present invention can make the high temperature waste residue of 1200 DEG C, therefore most waste heats of high temperature waste residue are all recovered utilization.By calculating, the energy equivalence that the high temperature waste residue that one ton of magnesium metal of every production produces discharges in cooling procedure is in the energy of 150kg standard coal, use the present invention not only can save a lot of fossil fuels, can also reduce the discharge of a large amount of dust, improve workman's work situation, reduce workman's labour intensity.
