概述 DESCRIPTION


脫硝技術主要是將含氮的還原劑(尿素、液氮或氨水)噴入到溫度850~1100℃ 煙氣中,使其發生反應,脫硝NO 生成氮氣和水。由於在一定溫度範圍及有氧氣的情況下,含氮還原劑對NO 的還原具有選擇性,因為反應中不需要催化劑,所以稱為非催化還原法。主要設備有:儲罐、泵、噴槍、管路、測控設備。

Denitration technology is mainly to inject reducing agent containing nitrogen (urea, liquid nitrogen or ammonia) into the flue gas whose temperature is 850 ~ 1100℃ to make them react to generate nitrogen and water. In a certain temperature range and the presence of oxygen, nitrogen reducing agent on the reduction of NO2 has selectivity, because the reaction does not need the catalyst, so called that non catalytic reduction method. Main equipment are storage tank, pump, spray gun, pipeline,test equipment.

工作原理 WORKING PRINCIPLE

1、投資成本和運行成本低,占地麵積小。

2、係統簡單,安裝期短,僅需10天左右停爐時間即可完成施工。

3、不需要更換引風機,對鍋爐運行不會產生影響。

4、該工藝是一項清潔技術,沒有任何汙染物生成,無二次汙染。

5、脫硝效率40~70%。

1,Low investment costs,low operating costs and small area.

2, Simple system,short installation period .

3, Do not need to replace the lead fan, the boiler operation will not have a impact.

4, The process is a clean technology, there is no pollution and no twice pollution.

5, Denitration efficiency is 40 ~ 70%.
