[0032] like Figure 1 to Figure 6 As shown, the technical solution adopted by the utility model is a flue gas heat absorption device 1, comprising a device body 2, an absorption component and a cleaning door component, wherein the device body 2 includes a first direction ( Figure 1 The device body 2 has a cavity 20 extending in the first direction (shown in the Z direction). The two ends of the device body 2 along the first direction are respectively provided with a smoke inlet 21 and a smoke outlet 22 connected to the cavity 20. The absorption assembly is arranged in the device body 2, and includes a plate group 30. The plate group 30 includes an intra-plate channel and an inter-plate channel. The inter-plate channel is connected to the smoke inlet 21 and the smoke outlet 22 for circulating smoke.
[0033] The cleaning door assembly includes a cleaning door 40, a rectangular frame 41, a first connecting plate 42, a second connecting plate 43 and a rubber gasket 44. The rectangular frame 41 is arranged on the device body 2 along the second direction ( Figure 1 The first direction is perpendicular to the second direction. The cleaning door 40 extends along the first direction and is used to close the rectangular frame 41. Along the second direction, the first connecting plate 42 is provided on the side of the rectangular frame 41 facing the cleaning door 40, and the second connecting plate 43 is provided on the side of the cleaning door 40 facing the rectangular frame 41. The first connecting plate 42 and the second connecting plate 43 are both provided at the corresponding connection between the cleaning door 40 and the rectangular frame 41. The rubber gasket 44 is provided between the first connecting plate 42 and the second connecting plate 43.
[0034] The flue gas heat absorption device 1 provided by the present application has cooling water circulating in the channel within the plate for heat exchange with the flue gas in the channel between the plates through the absorption component, thereby cooling the flue gas to the required temperature. In terms of the airtightness of the cleaning door 40, the cleaning door 40 and the rectangular frame are locked with bolts and are set to be not often open. When the plate group 30 needs to be cleaned, the cleaning door 40 is separated from the rectangular frame 41. The present application sets a connecting plate between the cleaning door 40 and the rectangular frame 41 to strengthen the tightness of the two when they are fixed. When the cleaning door 40 and the rectangular frame are closed and fixed, the connecting plates on both sides of the rubber gasket 44 will produce extrusion deformation on it, thereby ensuring the airtightness of the cleaning door 40 of the flue gas heat absorption device 1.
[0035] Furthermore, since the flue gas heat absorption device 1 also requires regular cleaning of the plates, the size of the cleaning door 40 cannot be miniaturized. The present application does not specifically limit the size of the cleaning door 40 as long as sufficient space is ensured for subsequent maintenance of the heat exchanger.
[0036] In some embodiments, reference Figure 1 to Figure 6 Along the second direction, a side of the first connecting plate 42 facing the rubber gasket 44 and a side of the second connecting plate 43 facing the rubber gasket 44 are both provided with a plurality of grooves 45. The plurality of grooves 45 are spaced apart on the surface of the connecting plate.
[0037] For example, when the cleaning door 40 is clamped with the connecting plate of the rectangular frame, the rubber gasket 44 can produce a certain amount of deformation in the groove 45 of the connecting plate, further ensuring the airtightness of the cleaning door 40 of the flue gas heat absorption device 1.
[0038] In some embodiments, reference Figure 1 and Figure 2 The plate group 30 includes a plurality of Figure 1 The heat exchange plates 31 are arranged at intervals (indicated by the X direction in the middle), and the first direction, the second direction and the third direction are perpendicular to each other. Each heat exchange plate 31 extends along the first direction and is provided with an intra-plate channel. Two adjacent heat exchange plates 31 form an inter-plate channel.
[0039] Exemplarily, the plate group 30 composed of a plurality of heat exchange plates 31 can change the number of plates and the gaps between them according to the working conditions, and can meet the cooling requirements of different conditions.
[0040] In some embodiments, reference Figure 1 to Figure 6 The absorption assembly further includes a plurality of distance bars 32. The plurality of distance bars 32 are respectively arranged at both ends of the plate group 30 along the first direction. Each distance bar 32 extends along the second direction and is fixedly connected to the plurality of heat exchange plates 31.
[0041] In some embodiments, reference Figure 1 to Figure 6The device body 2 includes a cooling water inlet 23 and a cooling water outlet 24. The cooling water inlet 23 and the cooling water outlet 24 are both arranged on the other side of the device body 2 along the second direction, and are both connected to the inter-plate channel, so that the external cooling water flows through the intra-plate channel.
[0042] Along the first direction, the cooling water inlet 23 is disposed close to the smoke outlet 22 , and the cooling water outlet 24 is disposed close to the smoke inlet 21 .
[0043] Exemplarily, the cooling water inlet 23 is arranged above the cooling water inlet 23, and the flow direction is opposite to the flow direction of the flue gas. Such countercurrent heat exchange can make the heat exchange between the two more complete.
[0044] In some embodiments, each heat exchange plate 31 is a pillow-type plate.
[0045] Illustratively, the present application utilizes the advantages of pillow-type plates, which have a smooth surface that is not easily adhered to dust or solid particles in the material. The plate group 30 can change the number and spacing of plates according to working conditions, and can meet the cooling of flue gas in different conditions. For example, if the particles in the flue gas are large, the distance between the plates can be increased to prevent blockage.
[0046] In some embodiments, reference Figure 1 to Figure 6 The flue gas heat absorption device 1 further comprises a mounting assembly. The mounting assembly comprises an ear seat 50 and a lifting ear 51.
