The invention discloses a front and rear curtain room waste gas purification device of a brazing furnace. The front and rear curtain room waste gas purification device can effectively reduce the brazing waste gas pollution. The front and rear curtain room waste gas purification device comprises a purification tower, wherein a gas inlet and an overhauling opening are formed in the upper end of the purification tower; a sealing cover is arranged on the overhauling opening and a gas inlet pipe is arranged in the middle of the gas inlet; the lower end of the gas inlet pipe stretches into the upper end of the purification tower; a gas spraying cover is arranged at the lower end of the gas inlet pipe; two layers of drawer-type filtering devices are arranged in the purification tower at the lower end of the gas inlet pipe; each drawer-type filtering device structurally comprises a drawer rail arranged in the purification tower, a drawer which is slidingly arranged on the drawer rail, and a handle and a furnace door fixing piece which are arranged on the outer side of the purification tower on one side of the corresponding drawer; active carbon is arranged in the drawers; a gas outlet is formed in the lower end of the purification tower; the gas inlet is connected with a draught fan fixedly arranged on a draught fan fixing frame through a connection pipe; an air outlet of the draught fan is connected with a waste gas outlet pipe.
Description
Technical field
The present invention relates to a kind of soldering oven, relate in particular to curtain chamber, a kind of soldering oven front and back waste gas purification apparatus.
Background technology
Soldering oven is that each aluminum heat exchanger parts are carried out to a kind of equipment effectively connecting.To utilize the alloy melting point of almit to weld lower than this characteristic of fusing point of aluminum metallic material.Solder is placed in conventionally to be needed near the solder side of connecting portion or the inside; between parts and solder side and surface scribble NOCOLOK aluminum brazing flux; after installation is dry, parts are heated to brazing alloy melting and the nonfused temperature of parts metal under certain inert gas shielding.Inert gas used is generally nitrogen.Simultaneously NOCOLOK aluminum brazing flux is broken the oxide-film of aluminium, allows and carries out diffusion into the surface between its motlten metal and infusible metal, cooling after, braze metal will and parts contact-making surface between form metal and be combined.Existing soldering oven produces waste gas in the indoor meeting of its soldering curtain of brazing process, and waste gas directly discharges by its exhaust, and contaminated environment does not reach discharging standards, contains toxic gas and particle and easily person health is easily worked the mischief in waste gas.
Summary of the invention
Technical problem to be solved by this invention is: curtain chamber, the soldering oven front and back waste gas purification apparatus that a kind of effective reduction soldering exhaust emission is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: curtain chamber waste gas purification apparatus before and after soldering oven, comprise: purifying column, be provided with air inlet and access hole in the upper end of described purifying column, on access hole, be provided with seal cover, middle part at described air inlet is provided with air inlet pipe, the lower end of described air inlet pipe extend into the inside, upper end of purifying column, in the lower end of air inlet pipe, jet lid is set, in the purifying column of described air inlet pipe lower end, be provided with two-layer drawer filter, the structure of described drawer filter comprises: the drawer rail that is arranged on described purifying column inside, be slidably arranged in the drawer on drawer rail, be arranged on handle and the fire door fixture in drawer one side purifying column outside, inside at described drawer is provided with active carbon, lower end at described purifying column is provided with gas outlet, described air inlet is connected with the blower fan being fixedly installed on fan fixed mount by tube connector, the air outlet of described blower fan is connected with waste gas outlet pipe.
Advantage of the present invention is: curtain chamber waste gas purification apparatus before and after above-mentioned soldering oven, and can effectively remove in waste gas and contain toxic gas and particle, directly discharge, does not pollute the environment, and can reach discharging standards, can easily not work the mischief to person health.
