Abstract

The invention provides an industrial waste gas heat recovery device. The industrial waste gas heat recovery device comprises an evaporator and a heat collecting device. The heat collecting device comprises a plurality of heating pipes and a T-shaped smoke inlet, smoke outlet branch pipes are arranged in inner cavities of the multiple heating pipes, and the smoke inlet ends of the multiple smoke outlet branch pipes are welded to a horizontal section of the T-shaped smoke inlet. Smoke outlets are formed in one sides of the multiple heating pipes distributed in a square matrix, a primary dust removal device is arranged on the T-shaped smoke inlet, and a secondary dust removal device is arranged below the smoke outlets. The secondary dust removal device comprises a dust removal chamber, a spraying device, a waste gas exhaust port and a drain outlet formed in the bottom of the dust removal chamber. The multiple heating pipes distributed in the square matrix mode are arranged in the evaporator, the energy absorption area of cold water is greatly increased, then the dust accumulation speed in the heating pipes can be effectively reduced by arranging the primary dust removal device and thesecondary dust removal device, and therefore, the energy absorption efficiency is further improved.

Description

technical field

[0001] The invention relates to the technical field of energy saving and environmental protection equipment, in particular to an industrial waste gas heat recovery device. Background technique

[0002] Since the beginning of the 21st century, with the rapid growth of the global economy and the acceleration of global integration, the contradiction between energy supply and demand has become increasingly prominent, and an important aspect of economic competition among various countries is reflected in energy competition. superior. With the increasing tension of world energy and the rising energy prices, the global ecological environment is also deteriorating day by day. The shortage of energy and the high price cause the continuous increase of manufacturing cost and the continuous increase of market competition pressure. How to effectively save energy, reduce emissions and protect the environment has become a major international issue facing the international...
