焦炉气初预热器工艺流程
英文回答：
The process flow of the coke oven gas primary preheater is as follows:
1. Gas Inlet: The coke oven gas enters the preheater through the gas inlet. The gas is usually at a temperature of around 40-50°C and contains impurities such as dust, tar, and sulfur compounds.
2. Dust Removal: The gas passes through a dust removal system, which includes cyclone separators and filters. These devices remove the dust and other solid particles present in the gas.
3. Heat Exchange: The gas then enters the heat exchanger section of the preheater. In this section, the gas flows through a series of tubes while hot flue gases from the coke oven combustion chamber pass over the tubes.
Heat is transferred from the flue gases to the coke oven gas, raising its temperature.
4. Flue Gas Outlet: The flue gases, which have transferred heat to the coke oven gas, exit the preheater through the flue gas outlet. These gases are usually at a lower temperature compared to their entry temperature.
5. Gas Outlet: The preheated coke oven gas exits the preheater through the gas outlet. The gas temperature at this point is typically around 250-350°C, which makes it suitable for further processing or utilization in various industrial applications.
6. Waste Heat Recovery: The hot flue gases exiting the preheater can be further utilized for waste heat recovery. This can involve generating steam, producing hot water, or generating electricity through a steam turbine.

焦炉气初预热器的工艺流程如下：
1. 气体进口，焦炉气通过气体进口进入预热器。

气体的温度通
常在40-50°C左右，并含有灰尘、焦油和硫化物等杂质。

2. 去尘，气体经过除尘系统，包括旋风分离器和过滤器。

这些
设备可以去除气体中的灰尘和其他固体颗粒。

3. 热交换，气体随后进入预热器的换热器部分。

在这个部分，
气体流经一系列管道，而来自焦炉燃烧室的热烟气则在管道上方流过。

热量从烟气传递到焦炉气体中，提高其温度。

4. 烟气出口，已经将热量传递给焦炉气体的烟气通过烟气出口
离开预热器。

这些烟气通常比进口时的温度要低。

5. 气体出口，预热后的焦炉气通过气体出口离开预热器。

此时，气体的温度通常在250-350°C左右，适合进一步处理或在各种工业
应用中利用。

6. 废热回收，离开预热器的热烟气可以进一步利用进行废热回收。

这可以包括产生蒸汽、生产热水或通过蒸汽涡轮机发电。
