Electrostatic atomization miniature combustor based on high-integration micron hole array

Abstract

The invention discloses an electrostatic atomization miniature combustor based on a high-integration micron hole array. The electrostatic atomization miniature combustor based on the high-integrationmicron hole array comprises a combustion catalysis cavity; a combustion outlet pipe and a fuel inlet pipe are separately arranged on the top and bottom of the combustion catalysis cavity; the fuel inlet pipe separately communicates with a material inlet pipe and a gas inlet pipe; a micron hole array electrostatic atomization unit and a collection catalysis unit are sequentially arranged at a material inlet of the material inlet pipe from outside to inside; the micron hole array electrostatic atomization unit comprises an electrostatic spraying cavity; one side of the electrostatic spraying cavity is connected to a fuel chamber through a pipeline; the other side of the electrostatic spraying cavity is sequentially provided with a micron hole array plate and a regulation electrode plate frominside to outside; the micron hole array plate and the regulation electrode plate are connected to a negative high-voltage power cathode, so that a first stage potential difference is formed; the collection catalysis unit comprises a collection grate which is grounded; and a second stage potential difference is formed between the regulation electrode plate and the collection grating; and by adopting the electrostatic atomization miniature combustor, atomization flow is greatly increased on the basis that submicron stage atomization liquid drips with good monodispersity are generated.

Description

technical field [0001] The invention belongs to the field of micro-combustion, in particular to an electrostatic atomization micro-burner based on a highly integrated micro-hole array. Background technique [0002] As one of the main types of micro power devices, micro burners have very obvious advantages. The energy density of the fuel can reach dozens of times that of the traditional chemical battery. The continuous combustion of the fuel can provide stable energy for the system for a long time, and there will be no energy loss as the storage time increases. At the same time, efficient and clean energy is selected as the fuel. It can effectively reduce environmental pollution and avoid the difficulty of collecting and disposing of batteries after they are discarded. This makes the micro burner have broad application potential in high-tech fields such as automotive electronics, aerospace, automatic control, and national defense. In micro power devices, people often choose ...

Problems solved by technology

However, although the micro-combustor has various advantages, it also faces some urgent technical problems with the reduction of its structural size.

The micro-burners currently on the market are mainly gas fuels that are easy to burn. Although these micro-burners have a certain atomization combustion effect, the micro-structure design is complicated and the processing is difficult. At the same time, compared with liquid fuels, gas The calorific value produced by the micro burner is significantly smaller

However, the atomization flow rate of the current liquid micro burner is low, the residence time of the fuel in the burner is short, the fuel liquid is difficult to atomize or the size of the atomized droplet is too large, the combustion is unstable and the combustion effect is not ideal
