Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology and solve the problem of waste heat recovery stainless steel heat exchangers in use, because the hot gas or water flow is mostly in a laminar flow state in the process of smooth flow, the heat exchange effect of the heat exchanger is not good, and the heat exchange efficiency is not good. High problem, the present invention provides a waste heat recovery stainless steel heat exchanger based on flue gas turbulence technology

Embodiment 1

[0027] see Figure 1-3As shown, a waste heat recovery stainless steel heat exchanger based on flue gas turbulence technology according to the present invention includes a heat exchange tube 1 made of stainless steel; A water flow channel 3 is formed between the pipe 1 and the water pipe 2. A set of rotary sleeves 4 is connected to the outer wall of the heat exchange tube 1 along its axial direction. The rotary sleeve 4 is connected with a spiral blade 5. The heat exchange tube 1 The fan blade 6 is rotatably connected to the position corresponding to the rotating sleeve 4 inside, and the magnetic layer 34 capable of attracting the fan blade 6 is inlaid on the spiral blade 5; the waste heat recovery stainless steel heat exchanger in the prior art is used When the hot gas or water flow is in a laminar flow state during the smooth flow process, the heat exchange effect of the heat exchanger is not good; while the waste heat recovery stainless steel heat exchanger in the present in...

Embodiment 2

[0036] see Figure 4 As shown, the outer end of the side wall of the oil storage chamber 18 corresponding to the two sides of the roller 20 is provided with an escape chamber 29, and the outer end of the lubricating body 21 is provided with an arc-shaped portion 30 protruding to the outside of the oil storage chamber 18; When the roller 20 drives the arc-shaped part 30 adsorbed with lubricating oil to move to the surface of the bump 7, the roller 20 and the bump 7 can squeeze the arc-shaped part 30 and make the lubricating oil inside it fully outflow, so as to play a more effective lubricating effect on the surface of the bump 7 .

[0037] The avoidance cavity 29 is connected with a sealing film 31 that is attached to the side wall of the roller 20, a magnetic body 32 is installed inside the lubricating groove, and a magnetic body 32 is attached on the inner wall of the sealing film 31 that can repel the magnetic body 32. The flexible magnetic strip 33; when the roller 20 is ...

Abstract

The invention relates to the technical field of fluid heaters, in particular to a waste heat recovery stainless steel heat exchanger based on a flue gas turbulence technology. The waste heat recovery stainless steel heat exchanger comprises a heat exchange pipe; a water pipe is arranged outside the heat exchange pipe in a sleeving mode, a water flow channel is formed between the heat exchange pipe and the water pipe, a rotating sleeve is connected to the outer wall of the heat exchange pipe, a spiral blade is connected to the rotating sleeve, fan blades are rotatably connected to the interior of the heat exchange pipe, and a magnetic layer 34 is embedded in the spiral blade. According to the waste heat recovery stainless steel heat exchanger, the spiral blades are driven to rotate through the acting force of water flow, the water flow can be stirred, the turbulent flow effect of the water flow is improved, hot air and the water flow conduct more uniform and efficient heat transfer through the heat exchange pipe, meanwhile, the spiral blades can drive the fan blades to synchronously rotate in the heat exchange pipe, and the turbulent flow effect of the hot air is promoted; and uniform and efficient heat transfer between the hot air and the water flow is further promoted, the heat transfer efficiency of the heat exchanger is improved, and waste heat can be recycled more sufficiently.

Description

technical field [0001] The invention relates to the technical field of fluid heaters, in particular to a waste heat recovery stainless steel heat exchanger based on flue gas turbulence technology. Background technique [0002] The heat energy of the air in the kiln can be completely recycled. Currently, there are two ways to recover the waste heat of the kiln. One is to recover hot air, such as using an induced draft fan to extract hot air from the kiln to dry the blank. The other is to recover hot water. If a number of water tanks are installed on the top of the slow cooling section of the kiln instead of the kiln roof, it can reduce the materials used in kiln manufacturing and recover hot water as daily water. [0003] However, when the waste heat recovery stainless steel heat exchanger in the prior art is in use, since the hot gas or water flow is mostly in a laminar flow state during the smooth flow, the heat exchange effect of the heat exchanger is not good, and the hea...
