Description

Technical Field

[0001] This utility model belongs to the field of dyeing and printing waste gas technology, and specifically relates to a dyeing and printing waste gas treatment device. Background Technology

[0002] Dyeing and finishing, also known as printing and finishing, is a processing method that encompasses pretreatment, dyeing, printing, finishing, washing, and other processes. my country is a major textile producer, ranking first in the world for many years. However, the dyeing and finishing industry is characterized by high energy consumption and heavy pollution. To improve energy conservation, emission reduction, efficiency, and clean production, the textile industry must not only continuously introduce advanced production equipment but also comprehensively promote energy-saving management measures and implement technological upgrades to minimize pollutant emissions and vigorously develop a green, low-carbon, environmentally friendly, and sustainable circular economy. Various processing stages in textile dyeing and finishing generate large amounts of wastewater and waste gas, especially during the drying and setting stages. The waste gas contains a large amount of gases with various chemical components, as well as a large amount of solid particles, such as synthetic fiber particles. Directly discharging this waste gas into the atmosphere would significantly increase environmental pollution. With the increasing environmental awareness of the country and its people, factory waste gas is now treated before being discharged to avoid environmental pollution.

[0003] Patent CN209679801U discloses a dyeing and printing waste gas treatment device. In this device, cooled waste gas enters a fixed chamber through a first gas supply pipe, a fan, and a second gas supply pipe. The waste gas passes through a filter screen to filter out impurities, which fall to the bottom of the fixed chamber. The filtered waste gas then passes through a packing plate to absorb acidic or alkaline gases. A water pump operates to pump tap water from a storage chamber through a first water pipe, a water pump, and a second water pipe, and then atomizes it through four nozzles to reduce the dust content in the waste gas. Finally, the waste gas is discharged into the outside atmosphere, thereby greatly reducing environmental pollution.

[0004] However, because the nozzle position is fixed, it cannot fully contact some of the exhaust gases, resulting in a mediocre effect in reducing the dust content in the exhaust gases. Utility Model Content
