Prior art is that the porous plate that ozone gas is punched by plastics is carried out gas distribution, the qi-emitting hole of this plastic multi hole plate is spaced, the ozone gas of discharging from qi-emitting hole can not be distributed to silicon chip surface by uniformly continous, moreover in actual production, silicon chip side by side 5 row or 8 row is advanced, this air distribution plate is also difficult to accomplish that the uniform air distribution of each row silicon chip corresponding is consistent, thus silicon chip effect can be caused inconsistent.
For this reason, applicants have invented a kind of gas uniform distribution device, can to gas uniform gas distributions such as ozone, fundamentally solve ozone gas distribution and the uneven problem of silicon chip.
Utility model content
According to above the deficiencies in the prior art, technical problem to be solved in the utility model is: provide a kind of gas uniform distribution device, can to gas uniform gas distributions such as ozone, fundamentally solves ozone gas distribution and the uneven problem of silicon chip.
A kind of gas uniform distribution device described in the utility model, comprise outside framework, described distribution device is provided with porous material layer, and porous material layer and outside framework surround cloth headroom.
Preferably, be provided with at least even gas-bearing formation of one deck in cloth headroom, between adjacent even gas-bearing formation and between even gas-bearing formation and porous material layer, be equipped with some horizontal channels of being separated by vertical isolation layer.
Preferably, even gas-bearing formation material is the material with micropore, even gas-bearing formation can be provided with some vertical channels be communicated with up and down, also can not establish vertical channel.
Preferably, even gas-bearing formation material is the material without micropore, and even gas-bearing formation is provided with some vertical channels be communicated with up and down.
Preferably, vertical channel is disposed alternately on even gas-bearing formation, and each horizontal channel below even gas-bearing formation is at least corresponding with the vertical channel of on even gas-bearing formation.
Preferably, the material of porous material layer is micropore ceramics or cellular plastic.
Preferably, the material of even gas-bearing formation is micropore ceramics or cellular plastic.
Preferably, the micro-pore diameter of porous material layer is 1 ~ 100 μm.
Preferably, the width of horizontal channel or height or diameter are 0.5 ~ 10mm, and the width of vertical channel or diameter are 0.5 ~ 5mm.
Compared with prior art, the beneficial effect that the utility model has is:
The gas uniform distribution device that the utility model provides, use the micropore board-like material of pore continuous distribution, by arranging even gas-bearing formation, overall formation layered composite structure, after the gases such as ozone enter distribution device from air inlet, successively through vertical channel and horizontal channel, finally arrive outermost porous material layer, after repeatedly evenly circulating, the gases such as ozone discharge distribution device from outermost porous material layer, serve the effect of even gas distribution.
