Abstract
The invention discloses a device for treatment of waste drying gas from sizing in textile dyeing and finishing and process for the same. The device comprises a collecting duct, a front fire resisting damper, a centrifugal wheel, a condenser, a honeycomb electric field, a plate line double-area electric field, a stream guidance duct, a rear fire resisting damper, a draught fan and a discharge duct which are connected in sequence, wherein the centrifugal wheel is installed on the electric machine. After being gathered by the collecting duct, the waste gas firstly enters into the centrifugal wheel for humidification and most of the oil drop and fiber with larger grain size are intercepted; the waste gas treated by the centrifugal wheel is cooled in the condenser and then enters the honeycomb electric field for pretreatment; after that, the oil gas enters the plate line double-area efficient purifying electric field for further treatment; finally the gas goes through the stream guidance duct and is discharged by the draught fan after coming up to the standard. The device of the invention integrates the advantages of several waste oil gas treatment technologies, has high purification efficiency, and can be widely used for the treatment of waste drying gas from sizing machine in the textile dyeing and finishing industry.

Forming machine is the key equipment of putting in order after the textile printing and dyeing; Temperature is higher in the cloth thermal finalization process; Therefore produce the great amount of high-temperature oil flue waste gas in the forming machine drying room; Contain polluters such as dyestuff, color additive (containing wax, solvent, emulsifying agent, high polymer monomer), lubricating oil, raising agent, fiber-like particle in the oil flue waste gas; Its main component is that aldehyde, ketone, hydrocarbon, aliphatic acid, alcohol, ester, lactone, heterocyclic compound, aromatic compound, particularly yarn have added lubricating oils in weaving process, and the composition of color additive is more complicated in the back arrangement of waterproof, functional fabric such as fire-retardant.Because scale expansion of printing and dyeing enterprise in recent years and gathering day by day of town dweller; The pollution problem that the toxic emission of dyeing forming machine causes is also outstanding further; Not only atmosphere is caused great pollution, the healthy of operator also caused damage, and influenced surrounding resident.
Although in fact domestic technology and the method that multiple improvement forming machine flue gas is arranged do not form and can effectively reclaim heat energy, can realize the complete set technology flue gas qualified discharge, stable and reliable operation and equipment again; External and supporting energy recovery and smoke gas treatment technology and the equipment of forming machine, because of costing an arm and a leg, safeguard reason such as inconvenience, domestic enterprise can't accept.According to market survey, domestic existing forming machine has only part to be equipped with the emission-control equipment of specialty, and most for spraying absorption plant, treatment effect is general.Also have few part enterprise to be equipped with electrostatic treatment devices, but energy consumption is big, poor stability is prone to block, and equipment cleaning etc. are inconvenience very.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of textile dyeing and finishing drying and shaping treatment of waste gas device and technology thereof of being used for is provided.
The electrostatic treating apparatus of condensation of dyeing and finishing shaping and drying waste gas comprises the conduit that links to each other in order, preceding fire resisting damper, centrifugal wheel, condenser, honeycomb electric field, printed line formula two-region electric field, conduction pipe, back fire resisting damper, air-introduced machine and discharge duct, and centrifugal wheel is installed on the motor.
The flat cone of rhombus that described centrifugal wheel constitutes for the bimetallic net.Described condenser is a water-cooled package class condenser.Described honeycomb electric field is rearranged by the hexagon hollow edged electrode that the center wears wire electrode.The ionized region that described printed line formula two-region electric field is made up of the line electric field and form by the adsorption zone that the plate electric field constitutes.
The step of the electrostatic treatment process of condensation of dyeing and finishing shaping and drying waste gas is following:
1) waste gas is introduced into centrifugal wheel through conduit and preceding fire resisting damper, and waste gas is carried out humidification and tackles bigger oil droplet of most of particle and fiber grain thing;
2) oil flue waste gas of handling through centrifugal wheel is lowered the temperature through condenser, reclaims part oily matter in the waste gas, improves the subsequent electric field processing security simultaneously;
3) get into honeycomb electric field through condensed waste gas and carry out preliminary treatment, reduce oil flue waste gas concentration;
4) get into printed line formula two-region electric field through pretreated waste gas and further handle, remove residue oiliness waste gas and particle, to reach discharge standard;
5) waste gas after handling discharges through air-introduced machine through conduction pipe and back fire resisting damper.
The present invention adopts the centrifugal wheel device both can remove the part oil smoke as pre-treatment; Can remove particles such as fiber again; But also can increase gas humidity, remedy simple dry method electrostatic apparatus and be prone to stop up, be prone to various deficiencies such as blast on fire, equipment cleaning frequency height; The front end of device adopts honeycomb electric field; Printed line dual zone type power supply is adopted in the rear end; Both given full play to the advantage of honeycomb electric field treatment of high concentration paroxysmal oil flue waste gas; Can utilize the advantage of printed line formula electrostatic field again, when having improved purification efficiency, also reduce the operating cost of electrostatic apparatus the distinctive high catch rate of the tiny soot particles of post-processing stages, low energy consumption; The security system design is careful, and fire resisting damper is set respectively in conduit and conduction pipe; Access door is opened, and high voltage source is promptly cut off automatically; The cell cube of the tight sealing of the well-designed one-tenth epoxy resin of high-voltage power supply, safe and reliable.
