Description

Technical Field

[0001] The invention relates to the technical field of industrial furnace flue gas waste heat recovery and utilization equipment, and in particular to a column heat exchanger. Background Art

[0002] Energy conservation is the key to the development of industrial furnaces. The level of energy consumption directly reflects the cost and value of products, and also affects product competitiveness and efficiency. Improving the utilization rate of enterprise energy is one of the effective ways to solve the contradiction between energy supply and demand. The energy utilization level of industrial furnaces in my country is still quite low, with an average thermal efficiency of less than 85%. The exhaust temperature of industrial furnaces is high. Effectively utilizing these large amounts of waste heat resources, especially the deep recycling and utilization of the potential released by condensed water in the flue gas, is the most effective energy conservation. At present, heat exchangers are generally used to recycle and utilize the waste heat of flue gas, and use the waste heat of flue gas to heat water or preheat air, thereby improving the heat utilization of industrial furnaces, saving fuel and reducing carbon dioxide emissions. The heat exchangers currently used have the disadvantages of being large in size, occupying a large space, being inconvenient to install, and not being able to be directly installed in the corners of flues with small spaces. Summary of the invention

[0003] The object of the present invention is to provide a column heat exchanger which occupies a small space and is easy to install.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a column heat exchanger, comprising a heat exchange cylinder formed by a plurality of serpentine tubes, which is open at both ends and sealed on the annular surface, one end face of the heat exchange cylinder is a flat end face, a mounting plate flange is fixed to the flat end face of the heat exchange cylinder, an inlet collecting box and an outlet collecting box are sleeved on the outside of the heat exchange cylinder, a water inlet collecting box inlet and a water inlet collecting box outlet are arranged on the inlet collecting box, a water outlet collecting box inlet and a water outlet collecting box outlet are arranged on the outlet collecting box, the water inlet pipe ends of all the serpentine tubes are connected to the water inlet collecting box outlet of the inlet collecting box, the water outlet pipe ends of all the serpentine tubes are connected to the water outlet collecting box inlet of the outlet collecting box, and a reinforcement support ring is fixedly sleeved on the outside of the heat exchange cylinder.

[0005] Furthermore, in the aforementioned column heat exchanger, a plurality of reinforcing plates are connected between the support ring and the heat exchange cylinder.

[0006] Furthermore, in the aforementioned column heat exchanger, the inlet and outlet water collecting ring boxes are both located on the flat end surface side of the heat exchange cylinder, and the inlet and outlet pipe ends of each serpentine tube are also located on the flat end surface side of the heat exchange cylinder.

[0007] Furthermore, in the aforementioned column heat exchanger, the other end face of the heat exchange cylinder is an inclined end face for facilitating corner docking.

[0008] Through the implementation of the above technical solution, the beneficial effects of the present invention are: a column heat exchanger is small in size, occupies a small space, is flexible and convenient to install, can be directly installed on the flue, and can also be installed in the flue corner with a narrow space, and has high heat exchange efficiency.

[0012] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0013] like Figure 1 , Figure 2 , Figure 3 As shown, the column heat exchanger comprises a heat exchange cylinder which is formed by a plurality of serpentine tubes 1 and is open at both ends and annularly sealed. One end face of the heat exchange cylinder is a flat end face, and a mounting plate flange 2 is fixed to the flat end face of the heat exchange cylinder. An inlet ring box 3 and an outlet ring box 4 are sleeved on the outside of the heat exchange cylinder. An inlet ring box inlet 31 and an inlet ring box outlet are arranged on the inlet ring box 3, and an outlet ring box inlet 41 and an outlet ring box outlet 4 are arranged on the outlet ring box 4. The inlet pipe ends of all the serpentine tubes 1 are connected to the inlet ring box outlet of the inlet ring box 3, and the outlet pipe ends of all the serpentine tubes 1 are connected to the outlet ring box inlet of the outlet ring box 4. A heat exchanger is also fixedly sleeved on the outside of the heat exchange cylinder. Strong support ring 5; in the present embodiment, a plurality of reinforcing plates 6 are further connected between the support ring 5 and the heat exchange cylinder, and the reinforcing plates 6 can further enhance the overall strength of the heat exchange cylinder, thereby improving the stability and safety of use of the heat exchanger; in the present embodiment, the water inlet collecting ring box 3 and the water outlet collecting ring box 4 are both located on the flat end surface side of the heat exchange cylinder, and the water inlet pipe end and the water outlet pipe end of each serpentine tube 1 are also both located on the flat end surface side of the heat exchange cylinder, which makes installation more convenient; in the present embodiment, the other end surface of the heat exchange cylinder is an inclined end surface for facilitating corner docking. Through the inclined end surface design of the heat exchange cylinder, it is only necessary to connect the inclined end surfaces of two column-type heat exchangers relative to each other, so that they can be installed in the corner of the flue with a narrow space, which makes installation and use more convenient.

[0014] The advantages of the present invention are: a column heat exchanger is small in size, occupies a small space, is flexible and convenient to install, can be directly installed on the flue, and can also be installed at the corner of the flue with a narrow space, and has high heat exchange efficiency.

[0015] The above description is only a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any modification or equivalent change made based on the technical essence of the present invention still falls within the scope of protection required by the present invention.
