The utility model has following effect:
1) structure is unique: it comprises outer cylinder body the waste heat boiler that the utility model provides, 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 inside above-mentioned inner barrel 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, the high-temperature water outlet, the outer cylinder body bottom is equipped with sewage draining exit and saddle from right to left successively, heat exchanger tube is horizontally fixed on the 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 the high temperature pelletizing pass through smoothly, cooling water is exported for the user by the high-temperature water outlet after being heated as high-temperature water by the 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 correspondence one by one.
2) the high temperature waste residue that utilizes method for smelting magnesium by hot to produce is heated as high-temperature water to cooling water as energy source, realized the recycling of energy: the waste heat boiler low-temperature cooling water that the utility model provides is flowed in waste heat boiler one side seal head by the 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; The 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 waste residue after being cooled.The Conversion of Energy that the high temperature waste residue that it can effectively produce the 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 ℃ because the utility model can make the high temperature waste residue of 1200 ℃, so most waste heats of high temperature waste residue all are 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 utility model not only can save a lot of fossil fuels, can also reduce the discharging of a large amount of dust, improve workman's work situation, reduce workman's labour intensity.
