Boiler waste heat utilization water heater

Abstract

The invention relates to the field of waste heat utilization, in particular to a boiler waste heat utilization water heater. The boiler waste heat utilization water heater comprises a hopper, a smokeinlet, a water feeding mechanism, first water valves, water pipes, a water box, supporting frames, a box body, a water drainage mechanism, water drainage pipes, second water valves, temperature gauges, a supporting mechanism, supporting rods, a supporting plate, heating mechanisms, first water heating boxes, second water heating boxes, a blocking mechanism, a first fixing plate, a baffle, a secondfixing plate, a smoke outlet and a sealing mechanism. According to the boiler waste heat utilization water heater, the side walls of the two ends of the box body are provided with the smoke inlet andthe smoke outlet correspondingly, the heating mechanisms distributed in a staggered mode are installed in the box body, waste gas enters the box body to make sufficient contact with the heating mechanisms, and thus, heat in the waste gas enters the heating mechanisms; and the side wall of the box body is rotationally connected with the sealing mechanism, the sealing mechanism is rotated so that the interior of the box body can be opened, the hopper is installed at the bottom end of the box body, dust inside the box body is removed through a shovel, and accordingly, dust in the box body and dust on the side walls of the heating mechanisms are discharged from the hopper.

Description

Technical field [0001] The invention relates to the field of waste heat utilization, in particular to a boiler waste heat utilization water heater. Background technique [0002] The boiler is a kind of energy conversion equipment. 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 certain thermal energy. The original meaning of pot refers to a water container heated on a fire, and a furnace refers to a place where fuel is burned. A boiler includes two parts: a pot and a furnace. The hot water or steam produced in the boiler can directly provide the required thermal energy for industrial production and people's lives, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. [0003] During the combustion process of the boiler, the exhaust gas generated inside the boiler contains a large...

AI Technical Summary

Problems solved by technology

[0003] During the combustion process of the boiler, the exhaust gas generated inside the boiler contains a lot of heat, and the heat is directly discharged into the air to waste heat; when the exhaust gas is used to heat hot water, a large amount of dust in the hot water is contaminated on the side wall of the water pipe, which is difficult to clean
