Method and device for removing steam and hydrogen sulfide generating from slurry stack

Abstract: PURPOSE: A method and a device for removing steam and hydrogen sulfate generating in slurry are provided to prevent early corrosion of peripheral facilities by removing steam and hydrogen sulfate generating in slurry and to improve working environment for workers. CONSTITUTION: A steam in mixed gas of steam, hydrogen sulfate and air generating in slurry(2) is removed by cooling water(12) flowing in the opposite direction of the flow of the steam in a spray tower(4). The cooling water supplied to the spray tower is cooled by a cooling tower(6) after use. The hydrogen sulfate flows into a hydrogen sulfate removal reactor(12) by a blower and removed by aqueous solution of caustic soda by neutralization. The aqueous solution of caustic soda is preferably maintained in 9.5pH and higher.

Anti-slurry-pollution method for spray tower observation window

Abstract: The invention discloses an anti-slurry-pollution method for a spray tower observation window. The anti-slurry-pollution method comprises the following steps that an inner sliding plate and an outer sliding plate are installed, the left sides and the right sides of the inner sliding plate and the outer sliding plate are provided with limiting devices, an inner sliding plate cleaning part is installed, a spray preparing phase is observed, spray is observed, and the upper half part of an inner transparent plate is cleaned. According to the anti-slurry-pollution method for the spray tower observation window, under the premise that an existing spray tower body structure is not changed and the gas-tightness of a spray tower is not influenced, a spray rod, a nozzle angle and the spray effect are observed conveniently through an existing observation window, the observation effect of the observation window is clear, and the observation window is not prone to being polluted.

Waste gas treatment device of smelting furnace

Abstract: The utility model discloses a waste gas treatment device of a smelting furnace. The device is provided with an induced draft fan, a spray tower, a spray pump, an annular pipe, a short pipe and an ejector, waste gas exhausted by the smelting furnace is exhausted through the exhaust port and then enters the spraying tower under the action of the induced draft fan, spraying liquid is placed in the spraying tower, the spraying liquid enters the annular pipe through the drainage pipe under the action of the spraying pump, then enters the jet devices through the annular pipe and is sprayed out fromthe water outlets of the jet devices in an atomized state under the action of the jet devices. Compressed air with proper pressure can be introduced into the air suction port of the jet device as required, and the atomization degree of spraying liquid sprayed out of the water outlet of the jet device is adjusted; the minimum diameter of the water flow channel in the jet device is much larger thanthe spraying hole diameter of the atomizing spray head, blockage is not likely to happen, the atomization degree of sprayed spraying liquid is adjustable, the spraying effect is good, and the waste gas treatment effect is good.
