Abstract
The invention reveals an industrial tail gas full recycle apparatus. The apparatus comprises a reaction vessel; one end of a tail gas recovering pipe is connected with the reaction vessel, the tail gas recovering pipe is in a shape of an inverted U, a water pipe is arranged above the tail gas recovering pipe, and the other end of the tail gas recovering pipe extends into a solvent in a stainless steel enclosed pressure container; a pipeline connected with a vacuum pump is arranged in the stainless steel enclosed pressure container and is far away from the solvent in the stainless steel enclosed pressure container, and a condensation kettle communicated with the pipeline is arranged at the bottom of the stainless steel enclosed pressure container. The industrial tail gas full recycle apparatus converts exhaust gas into a variety of concentrates and enables the concentrates to be applied in other fields, which allows the effect of full recycle to be realized, thereby reducing waste of resources and increasing benefits for an enterprise; meanwhile, full recycle of tail gas enables tail gas not to enter into the air, thereby causing no pollution to the air and obtaining a good environmental protection effect.
Description
Technical field
The present invention relates to a kind of chemical industry environmental protection equipment technical field, the abundant recycle device of especially a kind of industrial tail gas.
Background technology
At present, the improvement method of industrial tail gas has three kinds: one, Production by Catalytic Combustion Process: the method is utilized certain catalyst to decompose or is made and becomes innocuous gas after the organic exhaust gas burning.Shortcoming is to reclaim organic substance, only has input, and does not produce any economic benefit.Two, absorption process: the method is to absorb organic exhaust gas with specific certain chemical solvent, and then separates.The rate of recovery of this method is too low, and limitation is also larger, due to up-front investment and operating cost all very high, cause economic benefit not obvious.Three, absorption method: the method be take the active carbon physical absorption as main, has applied range, and operating cost is low, recoverable, and the features such as remarkable in economical benefits, but its limitation is also very large.
In existing Chemical Manufacture, much high-temperature roasting tail gas is taked direct mode usually, this mode has certain defect, the one, a large amount of heat energy is underused, the more important thing is wherein corrosive gas such as the direct discharge of HCL, NOx etc., can pollute atmosphere.
In addition, adopt certain measure to process high-temperature tail gas, as a kind of chemical industry device emptying tail gas process heat-recovering system, this system heats water generates steam by tail gas as thermal source, and the steam of usining provides alternative energy as secondary heat source.This system only can be processed clean high-temperature residual heat, but does not consider containing corrosive tail gas.
Summary of the invention
The object of the present invention is to provide complete, recyclable, the free of contamination ammonium salt tail gas of a kind of utilization of resources to take full advantage of retracting device.
Technical scheme of the present invention is: a kind of industrial tail gas full recycle apparatus, comprise reactor, one end of the tail gas recycle pipe be connected with reactor, it is inverted U-shaped that the tail gas recycle pipe is, tail gas recycle pipe top is provided with water pipe, the other end of tail gas recycle pipe stretches in the solvent in the withstand voltage closed container of stainless steel, in the withstand voltage closed container of stainless steel, also be provided with a pipeline be connected with vavuum pump, this pipeline is away from the solvent in the withstand voltage closed container of stainless steel, and the bottom of the withstand voltage closed container of stainless steel is provided with a device for cleaning pipeline to concentration kettle.
In a preferred embodiment of the present invention, described tail gas recycle pipe tilts in the horizontal direction, and angle of inclination is 15 °.
In a preferred embodiment of the present invention, tail gas recycle pipe knee is provided with baffle plate, and described baffle plate one side is provided with a bath water pipe.
In a preferred embodiment of the present invention, the stainless steel Fine spray shower nozzle be provided with on described water pipe, and stainless steel Fine spray shower nozzle one end is in the tail gas recycle pipe.
In a preferred embodiment of the present invention, the liquid in the withstand voltage closed container of described reactor and stainless steel is water.
In a preferred embodiment of the present invention, described tail gas is the composition gas of the gas of ammonia and sulfur dioxide, sulfur trioxide, carbon dioxide and hydrogen chloride any one or more than one.
Of the present invention is a kind of industrial tail gas full recycle apparatus, by this industrial tail gas full recycle apparatus, waste gas is converted into to various concentrate, concentrate can be applied to other aspects simultaneously, reach the effect that takes full advantage of recovery, so not only to a resource shrinkage waste, also increased the performance of enterprises, simultaneously, the abundant recycling of tail gas makes gas can not enter in air, to air, can not pollute, have good environment protecting.
The accompanying drawing explanation
Fig. 1 is the structural representation of this industrial tail gas full recycle apparatus in industrial tail gas full recycle apparatus one preferred embodiment of the present invention;
In figure, each annex mark is as follows: 1, reactor, 2, the tail gas recycle pipe, 3, water pipe, 4, the withstand voltage closed container of stainless steel, 5, vavuum pump, 6, concentration kettle, 7, the stainless steel Fine spray shower nozzle, 8, baffle plate, 9, the bath water pipe.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Of the present invention is a kind of industrial tail gas full recycle apparatus, as shown in Figure 1: this industrial tail gas full recycle apparatus comprises reactor 1, one end of the tail gas recycle pipe 2 be connected with reactor 1, it is inverted U-shaped that tail gas recycle pipe 2 is, tail gas recycle pipe 2 tops are provided with water pipe 3, the other end of tail gas recycle pipe 2 stretches in the solvent in the withstand voltage closed container 4 of stainless steel, in stainless steel is withstand voltage closed container 4, also be provided with a pipeline be connected with vavuum pump 5, this pipeline is away from the solvent in the withstand voltage closed container 4 of stainless steel, the bottom of stainless steel is withstand voltage closed container 4 is provided with a device for cleaning pipeline to concentration kettle 6.After gas passes into reactor 1, ammonia and sulfur dioxide, sulfur trioxide, the arbitrary gas of carbon dioxide and hydrogen chloride is combined to form one or more ammonium salts and dissolves in solvent, this solvent is water, reactor 1 is carried out to high-temperature heating, and open vavuum pump 5, air pressure by gas from reactor 1, entering in tail gas recycle pipe 2, after gas enters horizontal tail gas recycle pipe 2, open the stainless steel Fine spray shower nozzle 7 on water pipe 3, solvent in stainless steel Fine spray shower nozzle 7 is water, formation ammonium sulfate can react when gas is encountered water, ammonium sulfite, ammonium carbonate or ammonium chloride condense on the tail gas recycle tube wall, now open the bath water pipe 9 at baffle plate 8 places, by the ammonium sulfite condensed on the tail gas recycle tube wall, ammonium sulfate, the ammonium salt such as ammonium carbonate or ammonium chloride pours in the withstand voltage closed container 4 of stainless steel, baffle plate 8 has played the effect that prevents solvent refluxing.When the solution in the withstand voltage closed container 4 of stainless steel reaches finite concentration, solution is passed in concentration kettle 6, through concentrated, carry out different disposal depending on different ammonium salts.Thereby play the effect of a recycling.
