Integrated incineration device capable of treating yellow phosphorus exhaust gas without pollution and recovering energy

Abstract

The invention discloses an integrated incineration device capable of treating yellow phosphorus exhaust gas without pollution and recovering energy. The integrated incineration device consists of a device body; the device body comprises a first combustion tower and a second combustion tower; a fluidizer is arranged on the bottom side of the first combustion tower; a first ejector positioned on theupper side of the fluidizer is arranged on the outer wall of the first combustion tower; a second ejector is arranged on the outer wall of the first combustion tower on the upper side of the first ejector; and the second combustion tower communicates with an exhaust gas absorption tower. The invention aims to provide the incineration device that solves the problems of low treatment efficiency andhigh operating cost in the existing yellow phosphorus exhaust gas treatment, treats the yellow phosphorus exhaust gas, simultaneously performs energy recovering and reducing the operating cost.

Description

technical field [0001] The invention relates to the technical field of yellow phosphorus tail gas treatment, in particular to an integrated incineration device capable of pollution-free treatment of yellow phosphorus tail gas and energy recovery. Background technique [0002] Due to the presence of sulfur, phosphorus, and fluoride pollution and corrosive gases in the yellow phosphorus tail gas, it is difficult to treat and utilize the gases. At present, the treatment of yellow phosphorus tail gas adopts the mode of pressure swing adsorption and water washing plus alkali washing for pretreatment before utilization. Problems existing in the two methods at present: 1. Due to the high investment and operating costs of the pressure swing adsorption method, it is difficult to maintain industrial production. 2. The pretreatment method of water washing and alkali washing has low pollutant removal efficiency, which causes subsequent energy recovery equipment to corrode, and there ar...
