Abstract

The present invention provides one kind of comprehensive utilization apparatus of fume desulsurizing side product, and features that the comprehensive utilization apparatus a fume desulfurizing set, an acetylene generator and a PVC synthesizer. The hydrogen and the chlorine the fume desulfurizing set produces and the acetylene the acetylene generator produces are led to the PVC synthesizer to synthesize PVC. The present invention integrates the fume desulfurizing chloralkali / sodium sulfate technological process and PVC producing technological process, and has the positive effects of lowering investment cost, lowering production cost and raising economic utility.

Description

【Technical field】 [0001] The invention relates to a comprehensive utilization device and method of flue gas desulfurization by-products. It belongs to the environmental protection field of flue gas desulfurization, and is especially suitable for flue gas desulfurization occasions with large flue gas volume and low electricity price (such as flue gas desulfurization of large thermal power plants). 【Background technique】 [0002] In the Chinese invention patent application CN 1389289A published on January 8, 2003, a device and method for desulfurizing waste gas by chlor-alkali / sodium sulfate method are disclosed. In this waste gas desulfurization device, salt (NaCl) is used as a raw material, and is electrolyzed in an electrolytic cell in the device to generate a desulfurizing agent NaOH solution, and the desulfurizing agent is sent to a flue gas desulfurization tower in the device for desulfurization and purification of flue gas. The purified flue gas is discharged to the at...
