Continuous slagging device for low temperature boiling chlorination furnace

Abstract

The invention relates to the field of accessory equipment of chlorination furnaces and discloses a continuous slag discharge device for a low-temperature boiling chlorination furnace. The device comprises a slag pre-discharge tank, a slag discharge valve, a slag outlet tube of a chlorination furnace, a slag outlet tube of the slag pre-discharge tank, and a slag discharge tube; the two ends of the slag outlet tube of the chlorination furnace are respectively an end A and an end B; where in the end A is connected with the low-temperature boiling chlorination furnace, the end B is connected with the slag pre-discharge tank, and the end A is higher than the end B; the two ends of the slag outlet tube of the slag pre-discharge tank are respectively an end C and an end D; wherein the end C is connected with the slag pre-discharge tank, the end D is connected with the slag discharge valve, and the end C is higher than the end D; the bottom of the slag pre-discharge tank is provided with a scrubbing gas inlet; the top end of the slag pre-discharge tank is provided with a waste gas outlet tube; the bottom of the slag discharge valve is provided with a slag discharge gas inlet tube; and the slag discharge tube is connected with the slag discharge valve. The continuous slag discharge device has the advantages of being good in sealing property, safe and reliable, environmentally-friendly, being easy to realize automatic control and a continuous slag discharge, and the like.

Description

technical field [0001] The invention relates to the field of auxiliary equipment for chlorination furnaces, in particular to a slagging device suitable for low-temperature boiling chlorination furnaces. Background technique [0002] At present, low-temperature fluidized chlorination furnaces and fluidized chlorination furnaces generally use mechanical slag discharge valves, and high-temperature powdery materials in the furnace can easily lead to slag discharge blockage. In addition, the slag discharged from the chlorination furnace contains residual waste gas (such as residual Cl 2 、TiCl 4 , HCl, etc.), which can easily lead to poor working environment and prominent environmental protection problems. Therefore, it is very necessary to develop a continuous slagging device for low temperature boiling chlorination furnace that can solve these problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a continuous,...
