Abstract
The invention discloses a recycling device for waste heat at an electro-fused magnesium furnace opening. The recycling device is characterized by comprising a closed electric furnace, a waste heat recycling part and a de-dusting part, wherein the closed electric furnace is composed of a furnace shell (1) and a furnace cover (2); the waste heat recycling part is composed of a raw material preheating chamber (3) and a waste heat boiler (4); the de-dusting part is composed of a dust remover (5) and a draught fan (6); the furnace cover (2) is covered on the upper opening of the furnace shell (1), thereby forming the closed electric furnace; and the furnace cover (2), the raw material preheating chamber (3), the waste heat boiler (4), the dust remover (5) and the draught fan (6) are connected in turn through pipelines. High-temperature dust and gas discharged from the electro-fused magnesium furnace opening firstly enter into the raw material preheating chamber so as to be subjected to first waste heat recycling treatment, and then enter into the waste heat furnace so as to be subjected to secondary waste heat recycling treatment and enter into the dust remover so as to be subjected to dust removing treatment, and finally enter into the draught fan so as to be discharged from the draught fan, thereby extremely recycling the waste heat while performing dust removal treatment on the dust up to the hilt.
Description
Technical field: the present invention relates to a kind of heat recovery device, especially a kind of electric-melting magnesium fire door heat recovery device,
Background technology: the temperature in the production process of electric-melting magnesium in the stove is up to more than 3000 degree, in discharging dust and waste gas, also to take away a large amount of heats, caused very big energy loss, through patent retrieval and factual survey, up to the present also do not see the technology of the heat recovery that electric melting magnesium furnace waste gas and dust are taken away and the example of application
Summary of the invention: in order to address the above problem, the invention discloses a kind of electric-melting magnesium fire door heat recovery device, the waste heat major part that the electric-melting magnesium fire door is discharged obtains recycling, thereby receive obvious energy-saving effect, realize that the technical scheme that above-mentioned purpose is taked is characterised in that: by closed electric furnace, waste heat recovery, dust removal part is formed, wherein closed electric furnace is made up of furnace shell and bell, waste heat recovery is by dog house, waste heat boiler is formed, the sealing bell covers interruption-forming closed electric furnace on furnace shell, and by pipeline with dog house, waste heat boiler, deduster, air-introduced machine connects successively, all equipment pipes all are to handle through insulation, high-temperature dust that fire door is discharged and gas at first enter dog house and carry out a waste heat recovery, enter waste heat boiler again and carry out secondary recovery, enter the deduster dedusting again, after air-introduced machine discharge, if to add hot water, then change the sequencing of dog house and waste heat boiler, beneficial effect of the present invention is: the present invention is owing to taked the sealing bell that furnace shell is sealed, prevented entering of cool ambient air, eliminated the cooling of cold air to waste heat, can reduce simultaneously the power of air-introduced machine, further save the energy, and make and be in negative pressure state in the stove, thereby helping exhaust improves the quality of products, owing to taked the secondary recovery technology, make the heat recovery rate further improve, in waste heat recovery, dust has also been carried out dedusting, can obtain energy-conservation, reduce discharging and triple effects of improving the quality of products.Further specify below in conjunction with drawings and Examples.
