由于透水磚在燒制的過程中，是很容易差生煙氣的，而煙氣也是比較污染環境的，根據相關環境標準的需求，我們在燒制的過程中就需要做好煙氣的處理，接下來我們來簡單的了解下，如何更好的控制煙氣排放。

Due to the fact that permeable bricks are prone to producing smoke during the firing process, which can also pollute the environment, according to relevant environmental standards, it is necessary to properly treat the smoke during the firing process. Next, let's briefly understand how to better control smoke emissions.

1、煙氣特性：在透水磚的生產過程中，一次和二次燒制過程是有區別的。隧道窯焙燒過程中，高溫煙氣或余熱煙氣由鍋爐引風機泵送至烘房烘干青磚；

1. Smoke characteristics: In the production process of permeable bricks, there are differences between the primary and secondary firing processes. During the tunnel kiln roasting process, high-temperature flue gas or waste heat flue gas is pumped by the boiler induced draft fan to the drying room to dry the green bricks;

2、焚燒前階段：焚燒前階段，透水磚應盡量采用工業廢渣作為燃料，如粉煤灰、鍋爐渣，其間SO2含量低，焚燒后，煙氣中的SO2的損害也較小。其次，必須嚴格選擇硫含量低于1%的原煤作為燃料。

2. Pre incineration stage: In the pre incineration stage, permeable bricks should use industrial waste residue as fuel as much as possible, such as fly ash and boiler slag, where the SO2 content is low. After incineration, the damage to SO2 in the flue gas is also relatively small. Secondly, it is necessary to strictly select raw coal with a sulfur content below 1% as fuel.

3、焚燒中段：透水磚焚燒中段，爐內摻入鈣元素，煙氣脫硫方式受外投煤焚燒條件控制，鈣元素質脫硫劑與原煤中的SO2無法接觸一盞茶，脫硫效率低，使用較少。

3. Incineration middle section: Permeable brick incineration middle section, calcium element is added to the furnace, and the flue gas desulfurization method is controlled by the external coal incineration conditions. Calcium based desulfurizers cannot contact a cup of tea with SO2 in the raw coal, resulting in low desulfurization efficiency and less use.

如果說，透水磚在生產加工過程中能夠改變升級一下生產工藝，可以有效改變現有的煙氣排放量，有助于環保行業建設。所以大家在日后的燒制過程中，也一定要做好煙氣的排放處理工作，為我們的環境保護出一份力。

If permeable bricks can change and upgrade their production process during production and processing, it can effectively change the existing smoke emissions and contribute to the construction of the environmental protection industry. So in the future firing process, everyone must also do a good job in the emission treatment of smoke, and contribute to our environmental protection.
