Device for collecting and eliminating flue gas in coaling end flue of coke oven

Abstract

The utility model relates to a device for collecting and eliminating flue gas from a coke oven charging burner head, which belongs to the field of coke oven coal charging and dust removal, and comprises a carbonization chamber, a sealed water tank, a circulating pump and a wet dust collector. The inner tube, the venturi tube is placed above the water surface of the water tank, the inlet end of the circulating pump is inserted into the water surface of the water tank, the outlet end is connected to the nozzle and placed at the entrance above the venturi tube, and the wet dust collector is connected to the upper side of the water tank. Using the principle of Venturi flow tube to generate negative pressure, the flue gas generated by the furnace head during the coal charging process is collected, washed by a water tank and purified by a wet dust collector, which solves the problem that the flue gas in the furnace head is prone to explosion, which is energy-saving and efficient. It is environmentally friendly, and the device can be placed on the coke pusher, which occupies a small space, is convenient to use, and is easy to control.

Description

technical field [0001] The invention belongs to the field of coal charging and dedusting of coke ovens, in particular to a device for collecting and eliminating flue gas at the coal charging head of coke ovens. Background technique [0002] The coke oven will produce a large amount of paroxysmal smoke and dust during the coal charging process; there are three distribution points of the smoke and dust: the furnace top relief hole, the riser pipe, and the machine side furnace door. In the traditional design of coke ovens, coal charging and dust collection in coke ovens adopts the method of smoke-guided combustion on the top of the furnace. A machine-side gas collection hood is installed between the ends of the machine-side furnace columns. The top of the gas-collection hood is connected with pipes and extends horizontally outside the riser. A retractable flue gas conduction pipe is arranged on the smoke guiding combustion vehicle, the fixed end is connected with the flue gas c...
