Through adopting above-mentioned technical scheme, when waste gas gets into the intake pipe along the air inlet, waste gas supports presses the air inlet liquid level, make the liquid level descend, thereby extrude the gas port liquid level and make gas outlet liquid level lifting, when the air inlet liquid level is less than the air duct, waste gas pressure direct action is in the air duct, when the pressure of air duct one end is greater than the other end, waste gas is promoted, thereby make waste gas get into the purifying liquid bottom and discharge, make waste gas and purifying liquid fully contact, gas after the purification piles up in the gas outlet, and give a power in the liquid level through the air inlet, thereby make the power that gas outlet department received more thereby let the gas of gas outlet compressed, thereby let the gas that lets in other department recycle of compressed.
Preferably, one end of the air duct at the bottom of the purification tube is provided with a plurality of fine air outlet holes.
Through adopting above-mentioned technical scheme, tiny venthole can let the better contact of exhaust gas purification liquid to better purification.
Preferably, the purification pipe is provided with a plurality of dividing nets above the air outlet.
Through adopting above-mentioned technical scheme, cut apart the net and cut apart the gas that the venthole came out for gas disperses more, thereby better and the purifying liquid contact.
Preferably, one end of the air duct, which is close to the air inlet, is provided with a one-way valve.
Through adopting above-mentioned technical scheme, the check valve can make inside keep certain atmospheric pressure to prevent to evolve the liquid entering, and lead to the reaction to go on in the air duct and cause the air duct to block up.
Preferably, a pressure relief valve is arranged at the air outlet and communicated with the external heating furnace.
Through adopting above-mentioned technical scheme, the relief valve prevents that air in the gas outlet from being compressed excessively and causing the damage of purifying column to with relief valve and heating furnace intercommunication, make the waste gas after the purification carry the waste heat and heat the fuel in the heating furnace, play combustion-supporting effect simultaneously.
Preferably, the bottom of the purification tube is provided with a liquid exchange hole.
Through adopting above-mentioned technical scheme, after the purifying liquid reacted a period with waste gas, the effective purifying substance in the purifying liquid reduced, supplemented the effective substance in the purifying liquid through trading the liquid hole to the purifying column keeps work.
Compared with the prior art, the utility model has the beneficial effects that: through promoting waste gas to purify and also make the waste gas of purifying solution compression after being purified to let better the being collected of waste gas, simultaneously through sending into waste gas purifying solution bottom and discharge, make waste gas and purifying solution fully contact, thereby the better harmful substance with in the waste gas purifies the elimination.

Detailed Description
In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only used for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the designated device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in figure 1, a printing and dyeing apparatus for producing with waste gas recovery structure, which comprises a bod, be provided with the purifying column 1 that is used for retrieving waste gas on the fuselage, purifying column 1 includes air inlet 2 and gas outlet 3, air inlet 2 is linked together with gas outlet 3 through purge tube 4, and be the setting of U type, the intussuseption of purge tube 4 is filled with the scavenging solution, 2 cross-sections of air inlet are less than 3 cross-sections of gas outlet, be provided with air duct 5 in the purge tube 4, 5 one end of air duct sets up in air inlet 2 department, the other end sets up in the bottom that purge tube 4 is close to 3 one end of gas outlet, 5 both ends of air duct are all less than the scavenging solution liquid level, air duct 5 is provided with a plurality of tiny ventholes 8 in 4 bottom one end of purge tube.
According to the hydraulic principle, the input power is divided by the input area and is equal to the output power divided by the output area, when the input area is smaller than the output area, the force required for pushing the input surface is smaller than the force of the output surface, so that when waste gas enters the air inlet 2, the liquid surface at the air inlet 2 is pushed, the liquid surface moves downwards, the liquid surface at the air outlet 3 is lifted upwards, air at the air outlet 3 is squeezed out, the air is squeezed to other places for reuse, meanwhile, when the liquid surface at the air inlet 2 is descended to the air duct 5, the pressure of the liquid at the air inlet 2 of the air duct 5 is higher than the pressure of the air duct 5 at the bottom of the purification duct 4, so that the waste gas is pushed to move towards the interior of the air duct 5 and is discharged along the bottom of the air duct 5, the discharged waste gas is in contact with the purification liquid, and a plurality of cutting nets 6 are placed on the movement path of the air through the natural floating effect, make the air at the come-up in-process with cut apart 6 contacts of net for cut apart 6 with the bubble and cut apart, thereby let the bubble become more tiny, thereby let the area of contact of waste gas and water strengthen, thereby let the harmful substance in the waste gas purify the neutralization.
