Process technology for turbulent wet-process flue gas desulfurization and desulfurization wastewater treatment

Abstract

The invention discloses a process technology for turbulent wet-process flue gas desulfurization and desulfurization wastewater treatment and relates to the technical field of environmental protection. A body of a device is provided with a flue gas inlet and a flue gas outlet and is fixed with a blow-off pipe, a desulfurizing agent supplementing inlet, a water pipe and a desulfurizing agent outlet, the body between the flue gas inlet and the flue gas outlet is fixed with a desulfurizing agent inlet, a first-stage turbocharging turbulator, a first-stage desulfurizing agent inlet, a receiving tank, a second-stage turbocharging turbulator, a second-stage desulfurizing agent inlet, a first water inlet pipe, a demister and another water inlet pipe respectively from bottom to top, a liquid outlet pipe of the receiving tank penetrates out of the body, the desulfurizing agent inlet is fixed with a spray nozzle, the desulfurizing agent inlet is fixed with a first-stage spray nozzle, the second-stage desulfurizing agent inlet is fixed with a second-stage spray nozzle, and the water inlet pipes are fixed with water spray nozzles; and the wastewater treatment process comprises the steps of collecting wastewater, filtrating, neutralizing with lime milk, precipitating, clarifying, neutralizing with hydrochloric acid and then draining. The process technology is applied to flue gas desulfurization and wastewater treatment; and the device is ingenious, and the effect is good.

Description

technical field [0001] The invention relates to the flue gas turbulent flow wet desulfurization and desulfurization wastewater treatment technology, which relates to the technical field of environmental protection. Background technique [0002] In the production process of some industrial enterprises such as barium carbonate, it is inevitable to emit flue gas / or tail gas, which contains a large amount of sulfur dioxide, which is not only harmful to human health At the same time, it has caused great damage to the environment. Therefore, the state has always carried out strict management on this, especially in recent years, the state has put forward stricter and newer requirements on the emission of sulfur dioxide - that is, the introduction of new emission standards. Under the stricter requirements of the new emission standards, the traditional flue gas and / or tail gas desulfurization equipment, due to its simple structure and poor pertinence, can no longer adapt to the new ...

AI Technical Summary

Problems solved by technology

Based on the inventor's professional knowledge and work experience and the unremitting pursuit of excellence in the cause, on the basis of serious and sufficient investigation, understanding, analysis, summary, and research on the existing known technologies and status "The key technology is to make the flue gas / or tail gas organically mix with the desulfurizer solution under the state of turbine turbulence and pressurization and fully carry out the chemical reaction, thus solving the existing known technology and the current situation - in the flue gas / or tail gas When spraying with water / or water plus desulfurizer solution—the two are poorly mixed with each other and cannot get sufficient chemical reaction—the problem of poor desulfurization effect is caused, so the "flue gas multi-stage turbocharger" has been successfully developed. Turbulent flow wet desulfurization device", which effectively solves the deficiencies, defects and drawbacks of existing known technologies and current status
