噴漆房廢氣處理常見(jiàn)的幾種方法
1、水噴淋凈化法:主要以水簾柜和噴淋凈化塔,或旋流凈化塔為主,其基本原理是用噴嘴噴出的霧氣將油漆細(xì)顆粒物融入水里,這樣就能夠?qū)⒔^大多數(shù)的油漆細(xì)顆粒物阻擋住,達(dá)到將污染物和空氣分離的作用;
1. Water spray purification method: mainly used for water curtain cabinets, spray purification towers, or swirl purification towers. Its basic principle is to use the mist sprayed out by the nozzle to integrate fine paint particles into the water, which can block the vast majority of fine paint particles and achieve the separation of pollutants and air;
2、等離子體凈化法:借助高能量的活性基團(tuán)分解有機(jī)廢氣,但由于其基本原理中有放電,易造成著火的情形,所以此辦法一般不會(huì)是用在處理噴漆有機(jī)廢氣中;
2. Plasma purification method: using high-energy active groups to decompose organic waste gas, but due to the basic principle of discharge, which can easily cause ignition, this method is generally not used in the treatment of spray paint organic waste gas;
3、冷凝回收法:噴漆造成的有機(jī)廢氣通過(guò)冷凝或濃縮后,能夠分離出來(lái)有使用價(jià)值的有機(jī)物,主要用于處理濃度高、溫度低、有機(jī)廢氣處理量小的工程,通常噴漆房處理有機(jī)廢氣不采用這種辦法處理;
3. Condensation recovery method: The organic waste gas caused by spray painting can be separated into valuable organic compounds through condensation or concentration. It is mainly used to treat projects with high concentration, low temperature, and small organic waste gas treatment volume. Usually, this method is not used for the treatment of organic waste gas in spray painting rooms;
4、催化燃燒處理法:是在催化劑的作用下,使有機(jī)廢氣中的碳?xì)浠衔镌跍囟容^低的必備條件下快速氧化變成水和co2,做到凈化的效果。但此辦法成本較高,適用于風(fēng)量大濃度低的有機(jī)廢氣;
4. Catalytic combustion treatment method: Under the action of a catalyst, hydrocarbons in organic waste gas are rapidly oxidized into water and CO2 under necessary conditions at lower temperatures, achieving purification effect. But this method has a high cost and is suitable for organic waste gases with high air volume and low concentration;
5、活性炭吸附法:利用活性炭的吸附特點(diǎn),可以吸附有機(jī)廢氣中的氣體,排出凈化后的氣體,這種辦法投入成本低少,但要定期更換活性炭,確保設(shè)備擁有良好的吸附功效。
5. Activated carbon adsorption method: By utilizing the adsorption characteristics of activated carbon, it can adsorb gases in organic waste gas and discharge purified gases. This method has low investment cost, but it requires regular replacement of activated carbon to ensure that the equipment has good adsorption efficiency.
6、吸附脫附催化燃燒法:吸附法及催化燃燒法的優(yōu)勢(shì),利用環(huán)保型吸附原料(蜂窩狀活性炭)吸附,在接引和后導(dǎo)入熱空氣完成脫附、解析,脫附后有機(jī)廢氣導(dǎo)入催化燃燒床無(wú)焰燃燒,將其完全凈化,熱氣體在設(shè)備中循環(huán)往復(fù)利用,大幅度降低能耗。此方法運(yùn)行穩(wěn)定性高、成本低省、運(yùn)行成本低、售后維修便捷等特點(diǎn),主要用于大風(fēng)量、濃度低的的有機(jī)廢氣處理,是現(xiàn)階段行業(yè)內(nèi)整治處理有機(jī)廢氣較成熟、實(shí)用的辦法。
6. Adsorption desorption catalytic combustion method: With the advantages of adsorption and catalytic combustion methods, environmentally friendly adsorption raw materials (honeycomb activated carbon) are utilized for adsorption, followed by the introduction of hot air to complete desorption and analysis. After desorption, organic waste gas is introduced into the catalytic combustion bed for flameless combustion, completely purifying it. Hot gas is cyclically utilized in the equipment, greatly reducing energy consumption. This method has the characteristics of high stability, low cost, low operating cost, and convenient after-sales maintenance. It is mainly used for the treatment of organic waste gas with high air volume and low concentration. It is currently a mature and practical method for the treatment of organic waste gas in the industry.
