Integration dust-removing and desulfurizing device

Abstract

The present invention relates to integrated dedusting and desulfurizing apparatus and process. The integrated dedusting and desulfurizing apparatus one outer cylinder and one inner cylinder to form one sandwich with tangent air inlet and one air outlet, one sandwiched sleeve connected coaxially to the lower part of the inner cylinder and communicated to the sandwich between the outer cylinder and the inner cylinder, one water tank communicated to the sandwiched sleeve, one dewatering unit coaxially fixed inside the inner cylinder and with one axial water pipe, and one horizontal sieve plate in the middle part inside the sandwiched sleeve. The present invention has well combined cyclonic dedusting and spray dedusting and desulfurizing, possesses high dedusting and desulfurizing efficiency, and is suitable for purifying fume of small boiler.

Description

technical field [0001] The invention belongs to a dust removal and desulfurization device in the field of environmental protection, in particular to an integrated dust removal and desulfurization device. Background technique [0002] my country is a large coal-burning country. The flue gas discharged from coal-fired boilers contains a lot of dust and sulfur dioxide. If it is directly discharged into the atmosphere, it will cause great pollution to the environment. The dust contained in the flue gas is suspended in the atmosphere, which is harmful to human breathing. System, atmospheric visibility and urban landscape will all have extremely adverse effects; moreover, the sulfur dioxide contained in the flue gas contacts with the water vapor in the air, forming acid rain, which seriously pollutes water sources and the ecological environment. With the development of the economy, protecting the environment while realizing industrialization has become the focus of attention of the...

[0002] my country is a large coal-burning country. The flue gas discharged from coal-fired boilers contains a lot of dust and sulfur dioxide. If it is directly discharged into the atmosphere, it will cause great pollution to the environment. The dust contained in the flue gas is suspended in the atmosphere, which is harmful to human breathing. system, atmospheric visibility and urban landscape will have extremely adverse effects; and the sulfur dioxide contained in the flue gas will contact with the water vapor in the air to form acid rain, seriously polluting water sources and the ecological environment

With the development of the economy, protecting the environment while realizing industrialization has become the focus of attention of the government and the people. There are many dust removal and desulfurization methods and equipment at home and abroad. The existing dust removal and desulfurization methods include dry, wet and semi-dry. Dust removal and desulfurization are carried out independently, and the working process is also completed in two or more independent systems. The dust removal and desulfurization system is relatively complicated, occupies a large area, and consumes a large amount of energy.

Although the integrated technology of dust removal and desulfurization has been reported, the method of dust removal and desulfurization is relatively single. The overall structure of the equipment is relatively complex, and the system is difficult to maintain
