Novel heat collecting device with rectangular layout

Abstract

The invention discloses a novel heat collecting device with rectangular layout. The novel heat collecting device comprises a gas inlet for inputting heat supply fluid and a gas outlet for outputting tail gas. The gas inlet is communicated with the gas outlet through more than one rectangular heat collecting unit. Each heat collecting unit comprises a group of heat collecting tubes including a plurality of heat collecting tubes communicated along the flowing direction of the heat supply fluid sequentially. The heat collecting tubes are distributed intensively and are arranged in a parallel manner, and corresponding ends of optional adjacent two heat collecting tubes are communicated through a transitional unit. The novel heat collecting device with the rectangular layout is simple and compact in structure, small in size, high in heat efficiency and high in heat supply speed, can realize full utilization of energy sources, and is widely applicable to the industrial and civil fields of heating equipment, tail gas waste heat recycling equipment, steam generating equipment and the like.

Description

technical field [0001] The invention particularly relates to a novel heat collecting device with a rectangular layout, which belongs to the technical field of industrial heat supply. Background technique [0002] Traditional heating equipment mainly adopts two working modes, namely "water pipe type" and "fire pipe type". Taking the boiler as an example, a "water tube boiler" (a water tube boiler) is a heat exchange medium such as water, steam or steam-water mixture placed in the tube, and the flame or flue gas burns and flows outside the tube to achieve heat supply. , while the "fire tube" boiler is to flow the fuel or the flue gas generated after the fuel is burned through the fire tube or smoke tube, and heat the water, steam or steam-water mixture outside the fire tube or smoke tube, thereby realizing heat supply. Among them, the "water pipe" heating equipment has the advantages of relatively small volume, high working pressure, good safety performance, and high thermal ...

AI Technical Summary

Problems solved by technology

Among them, the "water pipe" heating equipment has the advantages of relatively small volume, high working pressure, good safety performance, and high thermal efficiency, but its disadvantage is that a considerable part of the heat energy will be lost to the surrounding environment, resulting in heat loss. The utilization rate is low, especially in the case of fouling in the water pipes, etc., the energy utilization efficiency will be further reduced

The "fire tube" heating equipment has the advantages of large water capacity, large heat storage capacity, and relatively simple structure, installation, and operation, but it also has many defects, such as large overall volume, low thermal efficiency, and low evaporation intensity. higher

[0003] In view of the shortcomings of the aforementioned traditional heating equipment, the inventor of this case has provided a variety of improved design heating equipment in CN100516750C, CN101701747B and other invention patents. There are defects such as large volume, relatively low heating speed, and energy utilization rate needs to be further improved.
