Description

Technical Field

[0001] The utility model belongs to the technical field of denitration devices, in particular to a corona field generator. Background Art

[0002] Denitrification is the process of removing nitrogen oxides in chemical engineering. The applicant has designed a set of double-high ionosphere negative oxygen ion denitrification device, which adopts a tube bundle structure to form an uneven high-voltage electrostatic field between the precipitation pole tubes. Under the combined action of the corona field and the electromagnetic field, when the airflow containing water mist and nitrogen oxides passes through, the water mist airflow will produce negative oxygen ions in the ionosphere under the action of the high-voltage electrostatic superposition power supply. As a form of active oxygen, it can oxidize and decompose harmful substances in the airflow, such as nitrogen oxides and sulfur dioxide.

[0003] The key factors affecting this technical route are, on the one hand, the distribution of the airflow, and on the other hand, the effects of the corona field and the electromagnetic field. In order to ensure that the corona field is fully distributed inside and outside the vertically extending tube bundle, the current corona field generator is designed as a bottom-mounted structure, which fully reduces the impact of the tube wall on the corona field, but the water mist in the airflow will condense and deposit on the generator in large quantities, requiring frequent manual cleaning. Summary of the invention

[0004] The technical problem to be solved by the utility model is that a large amount of water mist in the air flow will condense and deposit on the generator, which requires frequent manual cleaning.

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

A plurality of connecting rods are fixed on the lower side of the protective tube, the collecting trough and the protective tube are fixed at the bottom of the guide arc surface, the protective tube is located outside the collecting trough, a drop port is provided on the top of the collecting trough, the drop port is maintained at the low point of the guide arc surface, an output pipe is provided on the bottom side of the collecting trough, a main electromagnetic valve is installed on the output pipe, a liquid level sensor is installed in the collecting trough, the liquid level sensor is connected to the main electromagnetic valve through a wire, a discharge rod passes through the guide arc surface, the lower metal cover and the upper metal cover from bottom to top, a closing surface is provided on the upper metal cover, a plurality of discharge rods are provided, a positioning ring is connected between the plurality of discharge rods, a pair of filter sheets are installed in the collecting trough, and filter material is filled between the pair of filter sheets.

[0007] Preferably, an electrode is fixed at the bottom end of the plurality of connecting rods, the lower end of the discharge rod is connected to the electrode, and the electrode is ring-shaped.

[0008] Preferably, the lower metal cover and the upper metal cover serve as a two-stage discharge tube, and gaps are provided between the lower metal cover and the upper metal cover, and between the lower metal cover and the guide arc surface.

[0009] Preferably, the connection point between the positioning ring and the discharge rod is located below the end of the discharge rod, and the end of the discharge rod is a discharge needle.

[0010] Preferably, a nozzle passing through the guide arc surface is installed inside the protection tube and outside the collecting tank, and a fan and a secondary electromagnetic valve are installed on the nozzle.

[0011] Preferably, a bracket is installed at the bottom of the guiding arc surface, and the bracket is fixedly installed with the external basic structure.

[0012] The connecting rod is used to install the electrode ring. The protective tube protects the collection tank from the outside. The collection tank is kept at the bottom of the guide arc surface. After the water mist condenses, it falls into the collection tank from the drop port. The liquid level sensor detects the water volume in the collection tank. When it exceeds the limit, the main solenoid valve on the output pipe is activated to discharge the water in the collection tank downward from the output pipe. The lower part of the discharge rod is connected to the electrode ring, and the corona field is formed through the discharge needle at its end. The lower metal cover and the upper metal cover form a two-stage discharge tube, so that the corona field is distributed from the inside to the outside along a nearly spherical state. The closed surface has a sealing effect on the upper metal cover. The positioning ring supports and fixes the discharge rod to ensure the stability of the discharge needle at the end of the discharge rod. The filter plate and filter material can intercept impurities settled in the airflow.

[0013] The utility model discloses a corona field generator. The corona field generator adopts a ring electrode, frees up the bottom space to install an independent condensate discharge channel, and can effectively avoid the deposition and accumulation of condensate on the surface of the corona field generator. The utility model is suitable for bottom installation inside a denitration device. BRIEF DESCRIPTION OF THE DRAWINGS
