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.

Embodiment 1

[0054] Example 1 see Figure 1a-Figure 1b The stacked heat collector 30 includes an intake pipe 310 and an exhaust pipe 320. One end of the intake pipe is provided with an intake port 311 for inputting heating fluid, and the other end is connected with a combustion chamber 34. One end of the tube 320 is provided with an exhaust port 321 for exhausting exhaust gas, and the other end is a closed end. The combustion chamber 34 and the exhaust port 321 are connected to each other via a number of vertically arranged heat collection tubes 33 in sequence along the traveling direction of the heating fluid. Connected. In addition, the heat collection tubes are divided into two groups, and are arranged in two layers stacked on top and bottom. Among them, the multiple heat collecting tubes located on the upper and lower layers are densely arranged to form a circular layout. The corresponding ends of any two adjacent heat collecting tubes among the plurality of heat collecting tubes distr...

[0061] Example 2 see Figure 2a-Figure 2b The stacked heat collector 40 includes an intake pipe 410 and an exhaust pipe 420. One end of the intake pipe is provided with an air inlet 411 for inputting heating fluid, and the other end is a closed end. One end is provided with an exhaust port 421 for exhausting exhaust gas, and the other end is a closed end. The intake port 411 and the exhaust port 421 are communicated with each other through a plurality of vertical heat collection tubes 43 that are sequentially connected along the traveling direction of the heating fluid. In addition, the heat collection tubes are divided into two groups, and are arranged in two layers stacked on top and bottom. Among them, the multiple heat collecting tubes located on the upper and lower layers are densely arranged to form a rectangular layout. The corresponding ends of any two adjacent heat collecting tubes among the plurality of heat collecting tubes distributed in the upper layer are connect...

Abstract

A stack thermal collector comprises an air inlet for inflowing of heating fluid and an air outlet for outflowing of exhaust. The air inlet is communicated with the air outlet through a plurality of collector units. Each collector unit comprises a group of collector tubes, and each collector unit comprises a plurality of collector tubes communicated in sequence along flowing direction of the heating fluid, the collector tubes are densely arranged and mutually parallel, corresponding ends of any two adjacent collector tubes are communicated through a transition mechanism, the collector units are sequentially stacked in a direction parallel to the axes of the collector tubes, and in the flowing direction of the heating fluid, the first collector tube in any one collector unit is communicated with the last collector tube in one collector unit above the former collector unit. The stack thermal collector is simple and compact in structure, small in size, high in heat efficiency and fast in heat supply, allows energy recourses to be fully utilized, and is widely applicable to heating equipment, exhaust waste heat recovery equipment, steam generation equipment and the like.

Description

Technical field [0001] The invention particularly relates to a stacked heat collector, belonging to the technical field of industrial heating. Background technique [0002] Traditional heating equipment mainly adopts two working modes, namely "water tube type" and "fire tube type". Take the boiler as an example. A "water tube boiler" places heat exchange media such as water, steam, or steam-water mixture in the tube, and uses flame or flue gas to burn and flow outside the tube to provide heat. , And the "fire tube" boiler is to flow fuel or the flue gas generated after the fuel is burned through the fire tube or smoke tube, and heat the water, steam or soda water mixture outside the fire tube or smoke tube to realize heating. Among them, the "water pipe" heating equipment has the advantages of relatively small volume, higher working pressure, better safety performance, and higher thermal efficiency, but its disadvantage is that a considerable part of the heat energy will be lost...
