Roasting sand furnace top high-temperature flue gas and micro powder recovery system

Abstract

The invention relates to the technical field of recycling of waste heat on the top of a roasting sand furnace, recovery and discharging of dust after being cooled and the like and discloses a roastingsand furnace top high-temperature flue gas and micro powder recovery system which comprises a roasting furnace feeding machine and a roasting shaft furnace, and a roasting sand raw material feeding port is formed in the bottom of one side of the roasting furnace feeding machine. For the roasting sand furnace top high-temperature flue gas and the micro powder recovery system, with arrangement of the roasting sand raw material feeding port, the effect of feeding sands is achieved; through cooperative arrangement of a first motor, a first transmission rod and a first screw rod, the first motor is powered on in the using process so as to start to work, and then the first transmission rod drives the first screw rod to rotate, so that the sands conveniently spirally raise into the roasting shaft furnace; and through cooperative arrangement of the roasting shaft furnace and a first natural gas combustion machine, the first natural gas combustion machine is ignited in the using process, gravels fall into an inclined plate, and therefore high-temperature roasting can be conveniently conducted on the sands.

Description

Technical field [0001] The present invention relates to the reuse of the roasting furnace, and the recovery, emissions such as dust removal, and the technical field of cooling, and in particular, the tape high temperature flue gas and micro-powder recovery system. Background technique [0002] Now the production line, due to the high temperature of the fins up to 400 °, the tank smoke gas can only be installed with cyclone, and a large amount of ultrafine high temperature sand cannot enter the bag dust removal to recover the environment, and the utilization of cleaning natural gas, fuel The cost is multiplied, and the utilization of energy savings is more urgent. [0003] The current high-end casting is extremely high, especially the high-temperature flue gas temperature of the hopples of the grateful sanding system, and contains a large number of high temperature micrometers fine sands cannot be effectively recovered, so the present invention provides a high temperature of a bak...

AI Technical Summary

Problems solved by technology

[0002] In the current production line, since the furnace top temperature can reach more than 400°, the flue gas on the furnace top can only be equipped with a cyclone dust collector. The cost has doubled, and the utilization of waste heat from the top of the furnace is more urgent in order to save energy

[0003] In the current high-end casting roasting sand industry, especially the high-temperature flue gas temperature of the furnace roof of the shaft furnace roasting sand making system is extremely high, and contains a large amount of high-temperature fine sand that cannot be effectively recovered. Therefore, the present invention provides a roasted sand furnace top high-temperature Flue gas and fine powder recovery system
