Description

Tail gas comprehensive recovery device
Technical field
The utility model relates to a kind of tail gas comprehensive recovery device, in particular for powdery sodium benzoate production process In tail gas comprehensive recovery device, belong to tail gas comprehensive reutilization technical field.
Background technology
Powdery sodium benzoate production process is:With sodium hydroxide neutralization reaction occurs in aqueous for benzoic acid, generates benzene Sodium formate solution, PhCOONa solution is dried into roller chip dryer and cut after activated carbon filtering adsorbing contaminant Piece, the sodium benzoate after section is crushed by pulverizer produces standard compliant powdery sodium benzoate product.
In powdery sodium benzoate production process, roller chip dryer can produce substantial amounts of water and steam in the drying process Also dust generation is had in vapour, crushing process thereafter, the tail gas that this two parts is produced is powdery sodium benzoate production process tail The constituent of gas.For above-mentioned tail gas, traditional processing method is that the dust for producing crushing process passes through sack cleaner The common discharge after water dust scrubber is handled of vapor produced after processing with section, although being arranged after being handled by this kind of mode Put tail gas and reach discharging standards, but sodium benzoate is soluble in water, and a small amount of benzene first is still contained in the water vapour of discharge Sour sodium powder dirt, is discharged in air not only to air born pollution, but also waste resource.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of that prior art is present, and provides a kind of structure composition rationally, makes With convenient and reliable, pollution can not only be reduced, raw material is saved, and has reclaimed water vapour, substantially, operating efficiency is improved energy-saving effect Be used for powdery sodium benzoate production process in tail gas comprehensive recovery device.
The purpose of this utility model is completed by following technical solution, a kind of tail gas comprehensive recovery device, and it leads To include a recovery spray column for being built-in with filler, the bottom of the recovery spray column is provided with inlet exhaust gas, and top is provided with tail Gas is exported, and described recovery spray column inner chamber is disposed with least three layers packing layer, at least filling out in the superiors from the bottom up The watering mechanism of external connection is provided with above the bed of material;The bottom for reclaiming spray column is provided with recovery water out, the recovery water out External recovery pond is connected by pipeline;A steam-water separator is connected at the top of the recovery spray column, the steam-water separation The top of device phoenix machine is drawn through blast pipe connection by an exhaust port.
As preferred:Described recovery pond is circumscribed with two-way reuse water pipe, connects Water spray through a feeding spraying pump all the way Mechanism, constitutes a reuse water loop, another road is directly connected to reuse wetting system;Described inlet exhaust gas is connected to one and uses shell The condenser that formula heat exchanger is constituted, tail gas is by connecting described inlet exhaust gas after the condenser, and the condenser is cold But described watering mechanism is attempted by by stop valve with water.
As preferred:Described watering mechanism is arranged on above every layer of packing layer, and is being reclaimed outside spray column and connect All the way afterwards by interface external connection, the top offgas outlet for reclaiming spray column is connected to the carbonated drink point that a kidney ellipsoid cylinder is constituted by pipe From device, cone tip part bullet directed downwardly is provided with the centre of the steam-water separator and connect under bullet, led by sector The air deflector of flow composition.
The utility model belongs to improvements over the prior art, and it has structure composition rationally, easy to use and reliable, can not only Pollution is reduced, raw material is saved, and has reclaimed water vapour, energy-saving effect is obvious, the features such as operating efficiency is improved.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in detail below in conjunction with accompanying drawing:Shown in Fig. 1, a kind of tail described in the utility model Gas comprehensive recovery device, it mainly includes a recovery spray column for being built-in with filler, and the bottom of the recovery spray column 6 is provided with tail Gas import 11, top is provided with offgas outlet 12, and the described inner chamber of recovery spray column 6 is disposed with least three layers from the bottom up Packing layer 10, is at least provided with the watering mechanism 9 of external connection in the top of packing layer 10 of the superiors;Reclaim the bottom of spray column 6 Recovery water out 8 is provided with, the recovery water out 8 connects external recovery pond 2 by pipeline;The recovery spray column 6 Top is connected to a steam-water separator 13, and the top of the steam-water separator 13 is drawn by an exhaust port through the connection of blast pipe 5 Phoenix machine 4.
Shown in figure, described recovery pond is circumscribed with two-way reuse water pipe, connects Water spray through a feeding spraying pump 3 all the way Mechanism 9, constitutes a reuse water loop, another road is directly connected to reuse wetting system;Described inlet exhaust gas 11 is connected to a use The condenser 1 that shell-and-tube exchanger is constituted, the tail gas inlet exhaust gas 11 described by being connected after the condenser 1, and it is described cold The cooling water of condenser 1 is attempted by described watering mechanism 9 by stop valve 14.
Watering mechanism 9 described in the utility model is arranged on above every layer of packing layer 10, and is being reclaimed outside spray column 6 And connect all the way afterwards by the external connection of interface 7, the top offgas outlet 12 for reclaiming spray column 6 is connected to kidney ellipsoid cylinder composition by pipe Steam-water separator, cone tip part bullet 15 directed downwardly is provided with the centre of the steam-water separator and is connect under bullet 15 , the air deflector 16 being made up of fan-shaped flow deflector.
The beneficial effects of the utility model are:The utility model passes through the tail gas that powdery sodium benzoate production process is produced After recovery tower processing, almost dry-steam is discharged, and has been prevented the discharge of sodium benzoate dust, has been saved production cost, is reclaimed Distilled water, has saved resource.
