原理介紹 / Process Characteristics

VOCs治理項目的專業性強，一次性投資大，后期運維費用高，企業投資壓力大，環保排放超標風險高。
在此背景下，宗亞環保創造性提出，工業園區有機廢氣（VOCs）治理 “分散收集、集中治理”的模式，采用“活性炭吸附罐” 分散收集、 氮氣熱脫附”集中治理的方式進行綜合治理。
該模式下業主方負責場地的提供，水電氣等公用工程的接入，以及項目的總投資和運行費用，宗亞環保負責項目的設備采購、加工、安裝、調試與運維，達標交付。

VOCs treatment project project is highly professional, one-time investment, the late operation and maintenance costs, business investment pressure, environmental emissions exceeded the high risk.
In this context, GooAir proposed that the industrial park organic waste gas (VOCs) treatment"scattered collection, centralized management" model, the use of "activated carbon adsorption tank" scattered
collection, "nitrogen thermal desorption" centralized management of the way to comprehensive management
In this mode, the owner is responsible for the provision of the site, water and electricity and other public works access, as well as the total investment and operating costs of the project,
Zongya environmental responsibility for the project procurement, processing,installation, commissioning and operation and maintenance.

工程案例 / Engineering case

上海某造漆廠: 3個車間5個吸附罐，距離間隔較遠，VOCs分散且間歇排放，主要成分是甲苯、二甲苯、乙酸乙酯等，采用“分散收集+集中治理”模式，
每個吸附罐25000 m3/h，每天24 h運行情況下，可回收溶劑0.8-1.0 t/d。
