Embodiment Construction

[0018] like figure 1 As shown, the condensing electrostatic treatment device for dyeing and finishing drying exhaust gas includes a collection pipe 1 connected in sequence, a front fire damper 2, a centrifugal wheel 3, a condenser 4, a honeycomb electric field 5, a plate-line double-zone electric field 6, and a guide Flow pipe 7, rear fire damper 8, induced draft fan 9 and exhaust pipe 10, centrifugal wheel 3 are installed on the motor.

[0019] The centrifugal wheel 3 is a rhombic oblate cone made of double metal mesh. The condenser 4 is a water-cooled shell-and-tube condenser. The honeycomb electric field 5 is composed of a hexagonal tubular electrode arrangement with a linear electrode in the center. The plate-line double-zone electric field 6 is composed of an ionization zone formed by a line electric field and an adsorption zone formed by a plate electric field.

[0020] like figure 2 As shown, the steps of the condensing electrostatic treatment process for dyeing an...

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.

Description

technical field [0001] The invention relates to a waste gas treatment technology, in particular to a treatment device and process for textile dyeing, finishing, drying and shaping waste gas. Background technique [0002] my country's light and textile industry is well developed and has become an advantageous industrial group with international competitiveness. While creating huge economic benefits for us, it also brings serious environmental pollution problems. [0003] The setting machine is the key equipment for textile printing and dyeing finishing. The temperature in the heat setting process of the cloth is relatively high, so a large amount of high-temperature fumes and waste gases are generated in the drying room of the setting machine. agent, polymer monomer), lubricating oil, fluffing agent, fiber particles and other pollutants, the main components of which are aldehydes, ketones, hydrocarbons, fatty acids, alcohols, esters, lactones, heterocyclic compounds, aromati...
