The device is simple in structure, large in power, and capable of quickening turnover of gases in a tank body and extracting the gases in etching liquid out to a fixed processing procedure, and prevents the gases from volatilizing into the air and further producing air pollution and harming a human body.
Description
Technical field
The utility model relates to device, especially relates to the device for the gas that extracts etching liquid recovering system, belongs to environmental protection equipment.
Background technology
The typical process of printed circuit board (pcb) processing adopts " graphic plating method ".Namely first (being the visuals of circuit) preplating one deck slicker solder resist layer on the outer Copper Foil part that needs to keep of plate, then erode remaining Copper Foil with chemical mode, is called etching.The PCB etching is divided into alkalescence and two kinds of acidity, and one is hydrochloric acid hydrogen peroxide system (acidity); Two is ammonium chloride ammoniacal liquor system (alkalescence).Alkaline etching liquid mainly is applicable to graphic plating metal resist layer, as plated with gold, nickel, leypewter, the etching of the printed board of tin-nickel alloy and tin, its characteristics are that etch-rate is fast, and lateral erosion is little, molten copper ability is high, etch-rate is easily controlled, and in the printed circuit board production process, etching is a very important technical process, needing to use a large amount of etching solutions, is also therefore an operation that produces the severe contamination source.Traditional governance approach is: specify the company that qualification is arranged to reclaim by environmental administration, adopt simple way, wherein contained copper is processed into copper sulphate, then process slightly discharging.This significant wastage that has not only caused resource is (in every kilolitre alkaline etching liquid except cupric, also have the ammonium chloride more than 240 kilograms, the chemical substances such as liquefied ammonia of 30 kilograms of left and right), and waste liquid does not obtain real radical cure, has therefore formed the transfer of pollution sources.
Barrier film is made by inert material, as the asbestos diaphragm of the medium-term and long-term use of chlorine industry.But the asbestos diaphragm unstable properties when containing calcium, magnesium addition in salt solution, easily generates precipitation of hydroxide in barrier film, reduces transmitance; In higher temperature with under the electrolyte effect, also can expand, get loose.Can add resin as reinforcing material in asbestos for this reason, or make micro-pore septum take resin as main body, all be improved aspect stability and mechanical strength.The cation-exchange membrane of chlor-alkali production exploitation in recent years is novel diaphragm material.it have to ion see through selective, can make chlorion basically not enter cathode chamber, thereby can make the extremely low alkali lye of sodium chloride content, alkaline etching liquid carries out resource recovery copper by hazardous waste recovery business at present, produce the copper sulphate product, its processing procedure need to consume a large amount of reagent, produce a large amount of washes, or the product purity that obtains is inadequate, and can not the Direct Regeneration etching solution, economic benefit is low, can not reclaim the etching solution of inefficacy, environment there is certain impact, and cause the energy resource consumption of transportation and cost to increase, because etching solution is poisonous liquid, when recycling, due to factors such as temperature, can produce the volatilization of gas in casing, the finite volume of casing, gas easily overflows, poisoning phenomenon easily appears after absorption of human body.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, be provided for extracting the device of the gas in etching liquid recovering system, this device simple in structure, power is large, can accelerate the circulation of gas in casing, with the volatilization the etching solution gas extraction out, to fixing treatment process, avoided gaseous volatilization in atmosphere, produced atmosphere pollution, human body has been produced harm.
The purpose of this utility model is achieved through the following technical solutions: the device that is used for the gas of extraction etching liquid recovering system, the housing that comprises inner hollow, described enclosure interior is provided with rotating vane, the housing below is provided with bracing or strutting arrangement, housing is connected with motor, motor is connected with rotating vane, and described housing is provided with air inlet and the air outlet that communicates with its inside, and air outlet is arranged on the top of air inlet.
Further, described housing comprises shape identical housing one and housing two, and housing one and housing two fit tightly and be overall structure, and motor is connected with housing one.
Further, described air inlet is arranged on housing two, and is provided with guide ring on housing two, and guide ring is communicated with rotating vane, and air inlet is arranged on guide ring inside.
Further, described guide ring is communicated with by screw with housing two.
Further, be provided with retainer ring on the port of described air outlet, and the internal diameter of retainer ring is identical with the internal diameter size of air outlet, the external diameter of retainer ring is greater than the external diameter of air outlet.
In sum, the beneficial effects of the utility model are: this device simple in structure, power is large, can accelerate the circulation of gas in casing, with the etching solution gas extraction of volatilization out, to fixing treatment process, avoided gaseous volatilization in atmosphere, produce atmosphere pollution, human body is produced harm.
