Vehicle-mounted sulfur, nitrate, dust and fluorine integrated deep purification device and using method

Abstract

The invention discloses a vehicle-mounted sulfur, nitrate, dust and fluorine integrated deep purification device which comprises a vehicle head, a container connected to the rear portion of the vehicle head and a purification system, and the purification system is arranged in the container. The purification system comprises a purification tower I and a purification tower II; wherein the purification tower I comprises a tower body I, a corona electrode I and a conductive filter body; the purification tower II comprises a tower body II, a corona electrode II, a spraying system and an electric filtration coupling body; aiming at different types of to-be-treated gas, the flowing path of the to-be-treated gas in the device is changed by adjusting the opening and closing of a valve on a pipelineor changing the type of a flange, so that the serial connection or parallel connection or entering sequence of the purification tower I and the purification tower II is realized; according to the device, sulfur, nitrate, dust and fluorine in tail gas are effectively removed through the effects of electric dust removal, filter cloth dust removal, spraying dust removal, spraying absorption, free radical catalytic oxidation and the like, the ultralow emission standard is achieved, and due to the design of the vehicle-mounted container, the device has the advantages of being high in maneuverability, capable of achieving movable operation and the like.

Description

technical field [0001] The invention belongs to the field of flue gas purification, and in particular relates to a vehicle-mounted sulfur, nitric acid, dust and fluorine integrated deep purification device capable of supporting multi-stage parallel connection and series connection and a use method thereof. Background technique [0002] The non-ferrous metal industry is a mineral processing industry, with large logistics volume and long process flow, and is one of the main industries that pollute the environment. Especially because the metal minerals in our country are low in grade, complex in structure, and often coexist with toxic metal and non-metallic elements, so a large amount of harmful waste residue (stone), waste water and waste gas are produced in each process of mining, dressing, smelting and processing, resulting in Serious environmental pollution. The production of non-ferrous metal industry may emit more than 300 million tons of greenhouse gases (equivalent to ...

The patent "Gas Purification Tower and Gas Purification Equipment" (authorized announcement number CN 208032296 U) discloses a gas purification equipment. The main innovation of this equipment is that there is a cutting device inside the tank, which can cut the filler Refinement can also effectively increase the contact area between bubbles and liquid medicine, but in essence, this purification method is still the traditional chemical reaction absorption, and the purification efficiency for fluorine, nitrate and other gases is not high, and it cannot adapt to various complex processes. Moreover, it is impossible to achieve integrated and efficient removal of harmful components such as sulfur, nitric acid, dust and fluorine

The patent "An Electrostatic Cyclone Dust Removal System Based on External Alternating Magnetic Strengthening" (authorized announcement number CN 203155405 U) introduces a method of changing the direction of the magnetic field force on charged particles in the dust collector through external alternating magnetic regulation, extending its The action time in the electric field finally removes the charged particles through the electric field. Although this method improves the removal efficiency of small particles, it prolongs the dust removal time, increases the operating cost, and is easily affected by the nature of the particles themselves and the dust concentration. Unable to maintain efficient and stable dust removal efficiency
