Embodiment 1

[0046] Embodiment 1, a kind of such as figure 1 with figure 2 The inner electrode of the dielectric barrier discharge reactor for treating granular organic matter shown is composed of stainless steel tube 1 and stainless steel powder sintered tube 2 alternately; the stainless steel tube 1 and stainless steel powder sintered tube 2 are sealed and connected to form a multi-stage composite The internal electrode of the formula (a multi-stage composite internal electrode with the combined functions of filtration, chemical catalysis and plasma oxidation). The stainless steel powder sintered tube 2 is a porous material with a rigid structure made of spherical or irregular stainless steel powder through compression molding and high-temperature sintering, and supports noble metal catalysts. The supported catalyst is preferably Au or Pt, and the loading capacity is generally 0.5-1 μg / cm 2 (outer surface area of ​​stainless steel powder sintered tube 2). That is, per cm 2 The outer...

Embodiment 2

[0048] Embodiment 2. A reactor designed and processed using the internal electrode described in Embodiment 1, such as image 3 Said, including housing 4, one end of the housing is an air inlet, and the other end is an air outlet; the outer wall of the housing 4 is wrapped with a metal conductor, and the metal conductor is grounded as an external electrode for dielectric barrier discharge; in the housing 4 The above-mentioned multi-section composite electrode is arranged in the middle, and the external AC power supply or pulse power supply becomes the inner electrode of the dielectric barrier discharge reactor; the end of the inner electrode close to the air inlet is closed, and the end of the inner electrode close to the air outlet is open and communicated with the air outlet; The gap between the inner wall of the housing and the outer wall of the stainless steel pipe 1 is 1-5 mm; the gap forms a dielectric barrier discharge gap, and the dielectric barrier discharge gap is conn...

Abstract

The invention discloses a dielectric-barrier discharging internal electrode for particle-state organic matter treatment. The internal electrode consists of stainless steel tubes (1) and stainless steel powder sintering tubes (2) which are sequentially and alternatively arranged, wherein the stainless steel tubes (1) and the stainless steel powder sintering tubes (2) are connected in a sealed mode, and accordingly the multi-section composite internal electrode is formed. The channels of the stainless steel tubes (1) and the channels of the stainless steel powder sintering tubes (2) form the inner channel (3) of the internal electrode. The stainless steel powder sintering tubes (2) are multi-hole metal reaction bodies. A noble metal catalyst is loaded on the outer surfaces of the stainless steel powder sintering tubes (2). The end close to an air inlet, of the internal electrode is closed, and the end close to an air outlet is opened and communicated with the air outlet. The invention further discloses a reactor manufactured by utilizing the internal electrode. The problems of uneven discharging, low discharging strength, poor organic matter degradation effect and the like of a conventional composite electro-catalysis dielectric-barrier reactor can be overcome.

Description

technical field [0001] The invention relates to an inner electrode of a dielectric barrier discharge reactor for treating particulate organic pollutants. Background technique [0002] Solid particles suspended in the air are called particulate pollution because they are harmful to organisms and human health. There are many types of particulate matter in the atmospheric environment, generally referring to dust particles, dust, mist, smoke, chemical smog and soot between 0.1-75 μm. Polycyclic aromatic hydrocarbons (PAHs for short) are also a kind of particulate organic compounds, composed of two or more benzene rings, such as naphthalene, anthracene, phenanthrene, pyrene, etc. PAHs mainly exist in the gas phase and particle phase in the atmosphere, among which the small molecular weight PAHs with 2-3 rings mainly exist in the gas phase, the distribution of PAHs with 4 rings in the gas phase and particle phase is basically the same, and the large molecular weight PAHs with 5-7...
