This application provides a device for measuring the pyrolysis rate of solid-liquid engine fuel based on radiation heating. The device includes a housing, a radiation heating unit, a temperature control unit, and a fuel surface regression measurement unit. The housing encloses a mounting cavity. The radiation heating unit is disposed in the mounting cavity and heats the end face of the fuel component using non-contact focused radiation heating. The temperature control unit is communicatively connected to the radiation heating unit. The fuel surface regression measurement unit measures the height change of the fuel component's end face in a non-contact manner and calculates the fuel surface regression rate. This radiation heating and non-contact measurement approach improves the accuracy of the test results and reduces the mechanical complexity of the test device. Furthermore, it avoids the problem of a hot metal plate covering the fuel surface, does not inhibit the true physicochemical behavior of the fuel component surface, and more accurately reflects the pyrolysis characteristics of the fuel.

This invention relates to the field of water pollution control technology and discloses the preparation and application of modified chitosan adsorption balls. The invention involves grafting modified nano-micron high-purity composite active iron onto chitosan, then mixing it with dried and crushed sludge. The modified nano-micron high-purity composite active iron is then reacted with the chitosan to modify it. First, the surface of the nano-micron high-purity composite active iron is made to have active functional groups, and then it reacts with chitosan. At this point, the chitosan also has a dispersing effect, resulting in better performance and achieving a synergistic effect of dual phosphorus removal. This invention has low cost, simple operation, and good economic benefits.
