This utility model relates to the field of boiler desulfurization conveying technology, specifically disclosing a boiler desulfurization conveying device based on multi-point distribution and multi-stage diameter variation synergistic optimization. The device includes a first main conveying pipe, one end of which is connected to a transmitter in a limestone compartment. This boiler desulfurization conveying device, based on multi-point distribution and multi-stage diameter variation synergistic optimization, constructs a multi-stage gradually narrowing conveying channel through conical diameter variations in the first, second, and third main conveying pipes. When limestone powder enters the conical section of the first main conveying pipe, the gradual contraction of the pipe cross-section accelerates the gas-solid two-phase flow, forming a stable jet that enters the second main conveying pipe. The flow velocity is further optimized through the conical transition section of the second main conveying pipe, and finally, the conical structure of the third main conveying pipe completes the three-stage acceleration process. This avoids limestone powder accumulation caused by a single pipe diameter and reduces pipe wear.

This utility model relates to the field of chemical cooling equipment technology, specifically a circulating cooling device that solves the problem of poor cooling effect of circulating cooling water on high-temperature wastewater in existing technologies. The device includes a main body with a spray assembly and a wastewater pipe. The spray pipe of the spray assembly is located above the wastewater pipe, spraying cooling water onto the pipe. A heat-absorbing assembly is located below the wastewater pipe to absorb heat from the cooling water. The beneficial effects of this utility model are: the spray pipe cools the high-temperature wastewater in the pipe by spraying cooling water onto it; the cooling water absorbs the heat from the wastewater and falls onto the heat-absorbing assembly, which further absorbs the heat, lowering the water temperature. This allows the cooling water to better absorb heat from the wastewater pipe when it sprays out again from the spray pipe, ensuring a consistent cooling effect.
