本发明公开了一种烧结机台车内部料层负压场的检测方法及装置，该方法包括：检测料层内部不同位置的温度Tt；检测不同位置上下测试孔的压力PA、PB；并根据上下测试孔形成的压差ΔP，利用伯努利定律计算不同位置的气体流速Vt。本发明解决了由于烧结料层内部横向和纵向上负压分布不均匀，所导致的能耗及废气排放量增加的技术问题。本发明方法不仅操作简单，测试成本相对较低，测试装置可多次循环使用，而且还可以通过大量测量计算温度、压差、气体流速等数值提高数据的可靠性。

The invention discloses a method and a device for detecting the negative pressure field of the material layer inside the sintering machine trolley. The method comprises: detecting the temperature TT at different positions inside the material layer; Detect the pressure PA and Pb of the upper and lower test holes at different positions; And according to the pressure difference formed by the upper and lower test holes Δ P. The gas velocity VT at different positions is calculated by Bernoulli's law. The invention solves the technical problem of increasing energy consumption and waste gas emission due to uneven negative pressure distribution in the transverse and longitudinal directions inside the sintering material layer. The method of the invention not only has simple operation, relatively low test cost, and the test device can be recycled for many times, but also can improve the reliability of data by measuring and calculating a large number of values such as temperature, differential pressure and gas flow rate.
