Example Embodiment

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] The embodiment of the present invention provides a boiler waste heat collection and utilization device, such as Figure 1-2 As shown, the smoke box 1 is included. The inside of the smoke box 1 is fixedly installed with a water tube 3 through a fixed block 2. The water tube 3 is a U-shaped heat exchange tube, and both ends of the water tube 3 penetrate through the smoke box 1 The top of the inner wall and extending to the top of th...

Abstract

The invention provides a boiler waste heat collection and utilization device, which relates to the technical field of boilers. The boiler waste heat collection and utilization device comprises a smokebox, wherein a water column pipe is fixedly arranged in the smokebox through a fixing block; two ends of the water column pipe penetrate through the top part of an inner wall of the smokebox and extend to the top part of the smokebox so as to communicate with a water inlet and a water outlet pipe; an air inlet pipe communicates to a position, close to the left side, of the bottom part of the smokebox; an air outlet pipe communicates to a position, close to the top part, of the right side of the smokebox; and a side box is fixedly arranged on a side wall of the smokebox. According to the boilerwaste heat collection and utilization device, a motor controls a turbine to move up and down on an outer surface of a screw rod, a mutual attraction force of an external magnet and an internal magnetdrives a clearing block to move up and down on an outer surface of the water column pipe, and a friction block slides up and down on the outer surface of the water column pipe so as to scrape dust onthe outer surface of the water column pipe, so that the occurrence of the phenomenon that increasing smoke dust accumulated on the outer surface of the water column pipe so as to cause the reducing of heat exchange efficiency and the relatively reducing of an economic value of a waste heat system is avoided.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a boiler waste heat collection and utilization device. Background technique [0002] During the use of boilers in iron and steel enterprises, a large amount of fuel is usually consumed, accompanied by a large amount of flue gas, and the exhaust gas temperature of boilers used in iron and steel enterprises is also very high. In the past, these high-temperature flue gases were directly discharged to the atmosphere. It caused a huge waste of resources. At present, in order to save energy, many technologies have been produced to recover the waste heat of this high-temperature flue gas. In the existing technology, the usually used waste heat recovery facility is a heat exchanger, which is a It is a device that can not only reduce the flue gas temperature, but also utilize the high-temperature flue gas to achieve the purpose of heat exchange. However, due to the drastic temperature fl...
