Desulfuration dust-collection white-elimination deep purification device

Abstract

The invention belongs to the technical field of atmosphere pollution treatment environment protection, in particular relates to a desulfuration dust-collection white-elimination deep purification device, and aims to solve the problems that large floor spaces are required and the operation cost is high since a common process in the market is a condensation-reheating process, that is, a flue gas cooler, an air cooler and a flue gas heater are arranged outside a tower. According to the technical scheme of the invention, the device comprises an absorption tower body, wherein a flue gas inlet and aflue gas outlet are formed in the upper end of the absorption tower body; the flue gas inlet is positioned lower than the flue gas outlet; the absorption tower body is provided with a demister, a condensed water spraying layer, a liquid collection layer, a slurry spraying layer and a slurry pool from top to bottom in sequence; the liquid collection layer comprises a liquid collection plate and aliquid collection disc which is arranged below the liquid collection plate; a flue gas inlet pipeline is further arranged on one side outside the absorption tower body; one end of a flue gas inlet pipeline is parallel to the flue gas inlet; the other end of the flue gas inlet pipeline extends between the slurry spraying layer and the slurry pool; a heat exchanger is arranged at the communicating part of the flue gas inlet and the flue gas inlet pipeline.

Description

technical field [0001] The invention belongs to the technical field of air pollution control and environmental protection, and in particular relates to a deep purification device for desulfurization, dust removal and white elimination. Background technique [0002] In recent years, society has developed rapidly, and many industrial activities have caused unavoidable air pollution. For sustainable development and to provide everyone with a superior and comfortable living environment, our country has invested heavily in air pollution control and governance. . There are many causes of air pollution, but the biggest problem is the removal of dust particles and sulfur dioxide in the exhaust gas. Sulfur dioxide is harmful to the environment and human health, and it is also the main cause of acid rain. Therefore, the removal and treatment of sulfur dioxide is an important topic in the field of environmental protection in my country. [0003] In order to solve the problem of "whi...
