Accompanying drawing explanation

For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in embodiment being described below required for make Accompanying drawing be briefly described.Obviously, described accompanying drawing is a part of embodiment of the present invention rather than all implements Example, those skilled in the art is not on the premise of paying creative work, it is also possible to obtain other designs according to these accompanying drawings Scheme and accompanying drawing.

Fig. 1 is the theory structure schematic diagram of the present invention.

Detailed description of the invention

Below with reference to embodiment and accompanying drawing, the technique effect of design, concrete structure and the generation of the present invention is carried out clearly Chu, it is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this Bright a part of embodiment rather than all embodiment, based on embodiments of the invention, those skilled in the art is not paying Other embodiments obtained on the premise of creative work, belong to the scope of protection of the invention.It addition, literary composition is previously mentioned All connection/annexations, the most singly refer to that component directly connects, and refer to add deduct by adding according to being embodied as situation Couple auxiliary less, form more excellent draw bail.Each technical characteristic in the invention, in the most conflicting conflict Can be with combination of interactions under premise.

Embodiment 1: a kind of triethylamine exhaust gas cleaner, including purifying casing 1 and dust-removing box 2, purifies casing 1 and removes Being connected by airway 3 between dirt casing 2, dust-removing box 1 is provided with the airway 5 connecting exhaust emissions source;Purify casing 1 to pacify Equipped with the exhaustor 6 of discharge tail gas, purification casing 1 is internal, and equipped with phosphate aqueous solution, the middle part of airway 3 is provided with strong fan 4, Airway 3 is provided with several steam vents in purification casing 1 inner section, and is arranged on the bottom purifying casing.

Owing to purifying casing 1 in the present embodiment, strong fan 4, dust-removing box 2 and emission source are connected states, in strength Under the effect of blower fan, the triethylamine tail gas in emission source is drawn to dust-removing box 2, makees due to gravity when dust-removing box 2 With the bottom making solid matter be settled down to dust-removing box 2, remove the inducing QI on tail gas removing dust casing 2 top after solid dust It is internal that pipe 3 is expelled to purify casing 1 through strong fan;It is provided with several steam vents, through strong owing to purifying airway 3 in casing Power blower fan 4 acts on, and tail gas is expelled to purify box house through several steam vents, and its triethylamine toxic substance is by phosphate aqueous solution Absorb.The setting of several steam vents can make tail gas form several vesicles at purification box house, can prevent from entering purification After casing, tail gas fails because speed is excessive to fully absorb Triethylamine gas in purifying casing;Rear nontoxic tail gas is through aerofluxus bank of tubes Go out.

Embodiment 2: as one of preferred embodiment, can be on the basis of above-described embodiment 1, in dust-removing box 2 Portion is provided with two pieces of different baffle plates of level height, and two pieces of baffle plates are arranged in the middle part of dust-removing box 2 with relative mode, two pieces of baffle plates with Horizontal angle angle is 30 °-70 °.Being provided with two pieces of different baffle plates of level height can make gas when dust-removing box 2 Meet certain obstruct, make gas rest on dust-removing box 2 time lengthening, and solid dust lattice can be kept off, it is achieved preferably remove Dirt effect.

Embodiment 3: as one of preferred embodiment, can be on the basis of the above embodiments 2, at dust-removing box 2 Inside installs dirt filtrating screen additional, can filter dust further, improves efficiency of dust collection.

Embodiment 4: as one of preferred embodiment, will be able to purify in casing 1 on the basis of above-described embodiment 1 The phosphate aqueous solution concentration in portion is adjusted to 1%-10%, purifies front in the middle part of casing 1 and has the elongated observation window sealed with lucite Mouthful.It is that 1%-10% phosphate aqueous solution possesses good purification triethylamine effect in concentration;It is provided with in the middle part of casing 1 owing to purifying The elongated watch window of machine glass capsulation, user can observe bubble by window and discharge state, can be strong according to practical situation regulation The power of power blower fan 3, it is to avoid because wind-force deficiency makes device stop purifying work, or make to purify not exclusively because wind-force is too big Problem.

Embodiment 5: as one of preferred embodiment, can purify on the basis of above-described embodiment 1,2,3 or 4 Phosphate aqueous solution within casing 1 soaks several hollow spheroids.Hollow spheroid can realize through purifying the tail in casing 1 QI excess now intercepts, and extends the tail gas time in phosphate aqueous solution so that the triethylamine composition in tail gas more fully absorbs.

Embodiment 6: the triethylamine exhaust purifying method of a kind of device applied in above-described embodiment, comprises the following steps:

Step 1: triethylamine tail gas is entered to dust-removing box and carry out dedusting;

Step 2: the tail gas after dedusting is passed through in the phosphate aqueous solution of 5% concentration purified in casing through strong fan effect;

Step 3: the tail gas after removing triethylamine is discharged.

The purification method of the present embodiment possesses advantage simple, efficient, is suitable for applying at different types of triethylamine clean Change environment.
