DETAILED DESCRIPTION

[0021] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0022] like Figure 2-4 As shown, a heat exchanger that can reduce costs includes a base 1 and a heat exchange body. The base 1 is formed of concrete material. The heat exchange body is arranged on the base 1. The heat exchange body includes a frame 2, a spray mechanism 3 and a heat exchange component. A water storage tank 11 is provided on the base 1. The heat exchange component is arranged in the frame 2. The spray mechanism 3 includes a water pump (not shown), a water outlet pipe 31 and a spray pipe 32. The water pump is arranged on the base 1. The water inlet end of the water outlet pipe 31 is connected to the water outlet end of the water pump. The water outlet end of the water outlet pipe 31 is connected to the spray pipe 32. The spray pipe 32 is installed on the frame 2. The spray pipe 32 is located above the heat exchange component. A plurality of spray heads are provided at the lower end of the spray pipe 32. Specifically, the spray mechanism 3 also includes a water delivery pipe. The water outlet end of the water pump is connected to the water delivery pipe. The water inlet end of the water outlet pipe 31 is connected to the side wall of the water delivery pipe. The water pump can extract water from the water storage tank 11 and then transport it to each water outlet pipe 31 through the water pipe.

[0023] In this embodiment, a heat exchange cavity is provided inside the frame 2, and a heat exchange component is installed in the heat exchange cavity. The heat exchange component can use conventional heat exchange fins or heat exchange tubes on the market. An air inlet pipe 21 and an air outlet pipe 22 are provided on the side wall of the frame 2, and the air inlet pipe 21 and the air outlet pipe 22 are connected to the air inlet end and the air outlet end of the heat exchange component respectively. The air inlet pipe 21 and the air outlet pipe 22 are connected to the flue gas equipment, so that the high-temperature flue gas generated by the flue gas equipment enters the heat exchange component through the air inlet pipe 21, and the flue gas after heat exchange and cooling is discharged from the heat exchange component through the air outlet pipe 22.

[0024] In this embodiment, the upper surface of the frame 2 is provided with an air outlet 23, and the air outlet 23 is provided with an air extraction component, which includes a motor 41 and a fan blade 42. The motor 41 is installed above the air outlet 23, and the fan blade 42 is connected to the output shaft of the motor 41. Specifically, the frame 2 is provided with an annular boss 24 at the air outlet 23, and a mounting frame is provided on the annular boss 24. The motor 41 is fixedly connected to the mounting frame, and the output shaft of the annular motor 41 extends into the annular boss 24. After adopting the above structure, the motor 41 drives the fan blade 42 to rotate, and the high-temperature air and water vapor generated inside the heat exchange cavity during heat exchange can be discharged through the air outlet 23. In addition, a protective net 25 is provided in the annular boss 24, and a perforation is provided in the middle of the protective net 25 for the output shaft of the power supply machine 41 to pass through. It can play a protective shielding effect, prevent large debris from falling into the air outlet 23 and colliding with the fan blade 42, effectively prevent the fan blade 42 from being damaged, and improve the service life of the air extraction component.

[0025] In this embodiment, a support portion 12 is provided on the base 1, and the frame 2 is mounted on the support portion 12. A plurality of air inlets 13 are provided on the front and rear side walls of the support portion 12, and the air inlets 13 are connected to the heat exchange cavity. A plurality of air guide plates 14 are provided inside the support portion 12. After adopting the above structure, external air can enter through the air inlet 13 and be guided by the air guide plates 14 to flow into the heat exchange cavity, so that the external air can contact the heat exchange component to achieve heat exchange, further improving the heat exchange efficiency of the utility model.

[0026] The working principle of the utility model is as follows: the air inlet pipe 21 and the air outlet pipe 22 are connected to the flue gas equipment so that the high-temperature flue gas can enter the heat exchange component. During heat exchange, the water pump transports the water in the water storage tank 11 to each spray pipe 32, which is sprayed into the heat exchange cavity by the spray pipe 32, thereby exchanging heat between the heat exchange component and the flue gas. Afterwards, the water after the spray heat exchange can drip down back into the water storage tank 11, achieving the effect of circulating water and effectively reducing the heat exchange cost. In addition, the external air can enter the heat exchange cavity through the air inlet 13 to heat exchange and cool the flue gas, further improving the heat exchange efficiency of the utility model. Afterwards, the exhaust component can discharge the high-temperature air and water vapor generated by the heat exchange in the heat exchange cavity from the air outlet 23.

[0027] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
