Boiler waste heat recovery equipment and recovery method thereof

Abstract

The invention discloses boiler waste heat recovery equipment. The boiler waste heat recovery equipment comprises a cold water tank and a boiler body. A water inlet is formed in the middle position ofthe upper end of the cold water tank; the cold water tank is connected to the boiler body through a water delivery pipeline; a first pump body is mounted on the water delivery pipeline; a heater is arranged at the bottom of the boiler body; a temperature sensor is mounted on one side of the inner wall of the boiler body; a buzzer is mounted on one side of the outer top of the boiler body; and a water outlet pipeline communicates to one side of the boiler body. In the heating process, gas-liquid separation is performed on generated flue gas through a cyclone separator, a liquid flows downward and reflows to the boiler body through a water pipe, and gas floats upward and enhances the temperature of the flue gas through the heater and a reheater, so that the boiler waste heat recovery equipment is relatively helpful to improve the flue gas waste heat recovery efficiency subsequently.

Description

technical field [0001] The invention belongs to the technical field of boiler waste heat recovery equipment, and in particular relates to a boiler waste heat recovery equipment, and also relates to a recovery method of the boiler waste heat recovery equipment. Background technique [0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. [0003] The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical en...

Problems solved by technology

[0004] However, in the prior art, the heat from the flue gas discharged from the boiler will gradually disappear as time goes on, and there is a lack of mechanical components to reheat the exhausted flue gas, resulting in unsatisfactory recovery efficiency of the final boiler waste heat; at the same time , the heating temperature inside the boiler is difficult to grasp and humanized prompts, often make the hot water continue to boil after boiling, resulting in a waste of hot water resources, so it needs to be improved
