Split type energy-saving desulfurization and denitrification dust removal device

Abstract

The invention provides a split type energy-saving desulfurization and denitrification dust removal device which comprises a purifying tower and a pre-treating dust-reducing tower, wherein an air outlet I on the upper part of the pre-treating dust-reducing tower is connected with an air inlet II on the lower part of the purifying tower through a connecting pipeline; a secondary self-pressing type automatic air curtain atomizing dust-reducing device is arranged at a joint of the connecting pipeline and the air inlet II; and a desulfurization liquid recovery device which is communicated with the secondary self-pressing type automatic air curtain atomizing dust-reducing device is arranged on the lower part in the purifying tower. According to the invention, the original integrated structure of the desulfurization device is designed as a split structure comprising the pre-treating dust-reducing tower and the purifying tower. The split type energy-saving desulfurization and denitrification dust removal device has the advantages of small volume, high desulfurization efficiency, convenience in processing, transporting, mounting and overhauling, capability of adopting a low-power desulfurizing agent circulating pump for reducing the loss of desulfurizing agent, capability of adopting the secondary self-pressing type automatic air curtain atomizing dust-reducing device and the desulfurization liquid recovery device for recycling the desulfurizing agent, capability of increasing the use ratio of desulfurizing agent, capability of reducing cost and excellent desulfurization and dust removal effects.

Description

technical field [0001] The invention belongs to the technical field of desulfurization and dust removal equipment, and in particular relates to a split type energy-saving desulfurization, denitrification and dust removal equipment. Background technique [0002] In recent years, as the country continues to deepen the control of air pollution, the emission of exhaust gas and dust from industrial kilns has become the primary task of current environmental protection control. At present, the integrated desulfurization and denitrification equipment, that is, the desulfurization tower, is mainly used in the market to process flue gas. The desulfurization tower with this structure has disadvantages such as large volume, high production cost, inconvenient transportation and installation, low desulfurization and denitrification efficiency, and safety hazards for high-altitude maintenance. Due to the high volume of the desulfurization tower, the required power of the desulfurizer circu...

AI Technical Summary

Problems solved by technology

At present, the integrated desulfurization and denitrification equipment, that is, the desulfurization tower is mainly used in the market to treat the flue gas. The desulfurization tower with this structure has disadvantages such as high volume, high production cost, inconvenient transportation and installation, low desulfurization and denitrification efficiency, and safety hazards for high-altitude maintenance.

Due to the large volume of the desulfurization tower, the required power of the desulfurizer circulation pump is also relatively large, and the power consumption increases accordingly, causing an economic burden of high operating costs to the user

In order to reduce production costs, the user only starts to use the desulfurization tower when dealing with inspections, so that the pollution to the environment cannot be well controlled at all.
