Problems solved by technology
[0002] Due to the small space in the furnace and the small amount of waste gas, the existing vacuum cracking furnace can be directly cooled by water spraying, which can basically ensure the safe use of the vacuum pump and the safety of gas discharge; Poor, and easy to cause a high defective rate to the product
The existing equipment does not have a pressure relief valve and a supplementary nitrogen device, so the expected effect cannot be achieved

The invention relates to a large-volume vacuum cracking furnace and belongs to the field of chemical fiber product processing equipment. The large-volume vacuum cracking furnace is characterized in that a track is arranged on a trolley support of the large-volume vacuum cracking furnace; a trolley moves in the extension direction of the track; a trolley driver drives the trolley to move into a furnace shell; a cavity is formed in the furnace shell; an electric heating tube is arranged in the cavity; the furnace shell is connected with a waste gas heater; the waste gas heater is connected with a heat exchanger. The large-volume vacuum cracking furnace provided by the invention has the benefits that gas is supplemented after heating, so that the temperature in the furnace is small in fluctuation, and the cleaning effect is ensured; the gas is exhausted through a vacuum pump after being cooled by two sections of shell and tube type heat exchangers connected in series, so that the use safety of the vacuum pump and the safety of gas exhaust are ensured; as a nitrogen pipeline is arranged in the furnace, when the temperature in the furnace exceeds the standard, a system automatically opens a nitrogen valve and conveys a certain quantity of nitrogen into the furnace, so that a polymer on a cleaning part in the furnace does not burn, that is, the equipment safety is ensured.
Description
technical field [0001] The invention relates to a large-volume vacuum cracking furnace, which belongs to the field of chemical fiber product processing equipment. Background technique [0002] Due to the small space in the furnace and the small amount of waste gas, the existing vacuum cracking furnace can be directly cooled by water spraying, which can basically ensure the safe use of the vacuum pump and the safety of gas discharge; but for a larger volume vacuum cracking furnace, the direct spray cooling effect It is not good, and it is easy to cause a high defective rate to the product. The existing equipment does not have a pressure relief valve and a nitrogen filling device, so the expected effect cannot be achieved. Contents of the invention [0003] The present invention provides a large-volume vacuum cracking furnace aiming at the above-mentioned deficiencies. [0004] The present invention adopts following technical scheme: [0005] A large-volume vacuum crackin...
