Description
Technical field;
The invention is the gas fitting that produces when being used to reclaim converter smelting.
Background technology:
Converter produces a large amount of carbon monoxide in smelting process, be commonly called as " coal gas of converter ", and the gasometer of collection " raw gas " contains a large amount of dust, and dust content is up to 20～25g/Nm
3, can not directly use, must carry out could using after the dedusting, the national requirements dust content is at 10g/Nm
3Below could use.At present, reclaim coal gas of converter and mainly adopt two kinds of wet method and dry method.Hydrometallurgic recovery, mainly form by secondary purification device and dewatering unit, the first step adopts sizing or manual setting overflow Venturi meter, its effect is to be the cooling of raw gas and thick dedusting, it is the smart dedusting of raw gas that the excessive unrestrained Venturi meter of automatic path transfer or its effect of employing circumferential weld washer are adopted in the second stage, the dewatering unit effect is the moisture that removes in the piped gas, has a considerable amount of hydrometallurgic recovery device dust concentrations to exceed standard at present.The dry back receiving apparatus mainly is made up of evaporative cooler, electrostatic precipitator and gas cooler etc., and it invests high, and the fault of electric precipitation is many, unloads grey difficulty etc.
Summary of the invention:
The purpose of the invention provides a kind of dry cloth bag purifying recovery device of converter coal gas that dust content in the coal gas of converter that reclaims is up to state standards and requires; The purpose of the invention is to realize by following technical scheme: dry cloth bag purifying recovery device of converter coal gas, it is characterized in that by waste heat boiler, telescopic joint, water-sealed valve, the atomizing cooling tank, pipeline fan, the coal gas Low-Pressure Pulse Bag Filter, the close pneumatic ash conveying plant of full envelope, spray cooler, the coal gas induced draft fan, little reflux, diffuse valve, the pipeline butterfly valve, blank-plate valve, the coal gas water seal, gas chamber is formed, the waste heat boiler outlet connects telescopic joint, the telescopic joint outlet connects water-sealed valve, the water-sealed valve outlet is connected with the import of atomizing cooling tank, the outlet of atomizing cooling tank is connected with the pipeline fan import, the pipeline fan outlet is connected with placed in-line coal gas Low-Pressure Pulse Bag Filter, the close pneumatic ash conveying plant of full envelope is installed in coal gas Low-Pressure Pulse Bag Filter bottom, the coal gas Low-Pressure Pulse Bag Filter connects spray cooler, spray cooler is connected with the import of coal gas induced draft fan, induced draft fan outlet respectively with the pipeline butterfly valve, blank-plate valve connects, the pipeline butterfly valve with diffuse valve and be connected, blank-plate valve is connected with the coal gas water seal, the coal gas water seal is connected with gas chamber, at coal gas induced draft fan entrance end little reflux is installed.
The advantage of the invention: owing to adopted placed in-line coal gas Low-Pressure Pulse Bag Filter, dust removing effects is remarkable, the requirement that is up to state standards of dust content in the coal gas of converter, because the close pneumatic ash conveying plant of full envelope is installed in coal gas Low-Pressure Pulse Bag Filter bottom, reduce environmental pollution, import and export at the coal gas induced draft fan little reflux is installed, control enters pressure, the flow of pipe network, owing to installed and diffused valve, underproof coal gas ignition has been diffused.
