Description

Technical Field

[0001] The invention belongs to the technical field of denitration devices, and in particular relates to a double-high ionosphere negative oxygen ion denitration device. Background Art

[0002] Nitrogen oxides are one of the main sources of atmospheric pollution. In many chemical production processes, the raw gas contains a certain amount of NOx, which must be removed first to meet the requirements of process production. Common removal methods include reduction, liquid absorption, plasma activation, biochemical denitrification technology and adsorption.

[0003] Plasma activation is a dry flue gas desulfurization and denitrification technology developed in the 1980s. It is characterized by the generation of free electrons and active substances in the flue gas, which can remove NOx and SO2 at the same time. This method can be divided into two categories: electron beam method (EBDC) and pulse corona plasma method (PPCP). The former uses an electron accelerator to obtain a high-energy electron beam (500-800keV), and the latter uses pulse corona discharge to obtain active electrons (5-20eV). The corona method is developed from the electron beam method. This method overcomes the defects of the electron beam method, saves expensive accelerators, avoids problems such as electron gun life and X-ray shielding, and can be directly applied to existing dust removal devices. In the corona discharge process of this method, the activated electrons generated collide with gas molecules to produce free radicals such as OH, N, O and O3. These active substances first convert gaseous SO2 and NOx into high-valent oxides, and then form HNO3. In the case of ammonia injection, fine aerosols such as ammonium nitrate are further generated. The product can be collected by conventional methods (ESP or bag) to complete the separation from the gas phase. In the prior art, the removal efficiency of nitrogen oxides by conventional process methods still needs to be improved. In this case, how to develop more efficient denitrification equipment is a technical problem that needs to be solved in this field. Summary of the invention

[0004] The present invention aims to provide a double-high ionosphere negative oxygen ion denitrification device to address the technical defects of the prior art, so as to solve the technical problem that the removal efficiency of nitrogen oxides of conventional denitrification devices needs to be improved.

[0005] In order to achieve the above technical objectives, the present invention adopts the following technical solutions:

[0006] A double-high ionosphere negative oxygen ion denitrification device comprises a warehouse body, an air distributor, a mist and a voltage balancer, and an electronic control device, wherein a precipitation electrode tube is provided in the warehouse body, a cathode corona wire is provided on each precipitation electrode tube, a mist and a voltage balancer is provided on the lower side of the precipitation electrode tube, and an air distributor is provided at a position below the mist and voltage balancer in the warehouse body; the electronic control device comprises a humidity sensor, an ionosphere sensor, a humidity sensing probe, an ionosphere sensing probe, and a central processing unit, a humidity sensing probe is provided on the humidity sensor, an ionosphere sensing probe is provided on the ionosphere sensor, the humidity sensing probe and the ionosphere sensing probe are arranged in the warehouse body, and the humidity sensor and the ionosphere sensor are both electrically connected to the central processing unit.

[0007] Preferably, the denitration device is provided with a high-voltage electrostatic superposition power supply device, and the high-voltage electrostatic superposition power supply device adopts a combination of SCR chopper amplitude modulation and IGBT frequency modulation.

[0008] Preferably, it also includes an intelligent manager and a power cord, wherein the intelligent manager is electrically connected to the central processing unit, and the power cord is connected to the intelligent manager.

[0009] Preferably, the two electrodes in the denitration device are not coaxially arranged.

[0010] Preferably, the mist and voltage balancer are arranged in the superimposed power transformer. During the operation of the superimposed power transformer, when the voltage of a single group is lower than a threshold, another power supply starts to transmit a compensation voltage.

[0011] As a device for removing nitrogen oxides, the present invention is mainly provided with a high-voltage electrostatic superposition power supply device and an electric denitrification part. Its working principle adopts a tube bundle structure, and each precipitation electrode tube corresponds to a cathode corona wire. When working, the high-voltage electrostatic superposition power supply device is used, and the SCR chopping amplitude modulation and IGBT frequency modulation are combined to realize the independent control of the dual-adjustment excitation voltage. The humidity ratio and the matching voltage ratio can be accurately adjusted according to the ratio of nitrogen oxides to obtain the strongest ionosphere, and an uneven high-voltage electrostatic field is formed between the precipitation electrode tubes, and the two electrodes are arranged in different axes. The advantage of the different axis arrangement is that the ionosphere will be generated. Under the joint action of the corona field and the electromagnetic field, the negatively charged oxygen ions will generate negative oxygen ions in the ionosphere under the action of the high-voltage electrostatic superposition power supply when the airflow containing water mist and nitrogen oxides passes through. As a form of active oxygen, it can oxidize and decompose harmful substances in the airflow, such as nitrogen oxides and sulfur dioxide.

[0012] The advantage of the present invention is that when the water mist reaches a certain ratio in the ionosphere, a large amount of negative oxygen ions can effectively remove nitrogen oxides.

[0013] The structural feature of the present invention is that a superimposed power transformer is provided. The advantage of the superimposed power transformer is that when a single group voltage is weak, the other power supply will automatically start to deliver a compensation voltage to keep the voltage balanced. A mist and voltage balancer is provided in the superimposed power transformer to ensure that the charged ions react to produce the most negative oxygen ions, so as to remove nitrogen oxides with the maximum effect. The raw gas enters the device and passes through the dense array air distributor to evenly pass the airflow through the processor so that the airflow is fully compatible with the corona field, and the ideal treatment effect is achieved through deep treatment.
