Abstract

The invention belongs to the technical field of energy utilization equipment, in particular to a low-temperature waste heat utilization system. The system includes an absorbing-type heat pump, a low-temperature flue gas heat exchanger and a steam condenser, a generator, an evaporator and a condenser are arranged in the absorbing-type heat pump, a condensate outlet of the condenser communicates with a water inlet of a boiler, the low-temperature flue gas heat exchanger is connected with a flue way of the boiler, and a hot water outlet of the low-temperature flue gas heat exchanger is connectedwith a hot water inlet of a generator; and the steam condenser is connected with a gas exhaust pipeline of a steam turbine, a cooling water outlet of the steam condenser is connected with a cooling water inlet of the evaporator, and a condensate outlet of the steam condenser is connected with a condensate inlet of the condenser. The waste heat utilization system can reasonably utilize the low-temperature flue gas waste heat and the waste heat produced by the cooling circulating water, and the condensate is supplied to the boiler by using the waste heat after heating, so that the low-quality waste heat in the industrial production is continuously converted into the useful energy of the production system, and the heat loss during industrial production is reduced advantageously.

Description

technical field [0001] The invention belongs to the technical field of energy utilization equipment, and in particular relates to a low-temperature waste heat utilization system. Background technique [0002] Boilers are common equipment used to provide heat energy. They are mostly used in industries such as metallurgy, petrochemical, thermal power, and building materials manufacturing. For boiler heating systems, the heat loss of boiler exhaust is one of the most heat loss during boiler operation. Therefore, how to reduce the exhaust heat loss of the boiler is particularly important for saving energy and improving the economy of industrial production. In addition, in most cases, when setting boiler heating, it is necessary to equip circulating cooling equipment to provide cooling water to cool down the heat-producing or heat-consuming equipment. After the cooling water exchanges heat, the temperature rises, and part of the heat will also be lost. . [0003] In recent year...
