Spray type steel slag thermal steam treatment device

Abstract

The invention discloses a spraying type device for treating steam generated after thermally braising steel slag. The device comprises a slag braising pit used for stacking steel slag, wherein the top of the slag braising pit is hermetically covered by a slag braising cover; a gas outlet is formed in the side wall of the slag braising cover; the slag braising pit is communicated with a spray tower via a steam pipeline communicated with the gas outlet in the side wall of the slag braising cover; a plurality of straight pipes are circumferentially distributed in the spray tower; a plurality of ring pipes communicated with the straight pipes are installed in the spray tower from top to bottom at intervals; a plurality of spray pipes with nozzles are circumferentially distributed on each ring pipe; water is supplied to the straight pipes simultaneously via a water supply system; the steam pipeline extends into the spray tower from the center of the top of the spray tower; the steam pipeline extending into the spray tower is sleeved by the ring pipes in a ring manner. The device has the advantage that the device can be used for effectively treating steam generated after thermally braising steel slag.

Description

technical field [0001] The invention relates to a spray type steel slag thermal stewing steam treatment device. Background technique [0002] In the steelmaking industry, the steel slag after steelmaking is generally piled up in the slag slag pit, and then water is periodically pumped into the slag slag pit, so as to achieve the purpose of cooling and pulverizing the steel slag; A large amount of steam containing impurity particles is emitted. At present, these steams are directly discharged into the atmosphere, which greatly affects the ambient air quality. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a spray-type steel slag heat-steaming steam treatment device capable of effectively treating the steam generated after the steel slag heat-steaming. [0004] In order to achieve the above object, the present invention adopts the following technical scheme: the spray-type steel slag hot stewing steam treatment device includes: a slag s...
