Description

Technical Field

[0001] The utility model relates to the technical field of waste heat recovery, in particular to a waste heat recovery device for sludge collaborative waste incineration based on carbon neutralization. Background Art

[0002] Sludge is a by-product in the aerobic biological treatment of sewage by the activated sludge method, which contains a large amount of microorganisms, bacteria, heavy metals and synthetic organic substances. Improper treatment will endanger human health and pollute the environment. The sludge pyrolysis technology is to heat the dried sludge to a certain temperature in an anaerobic environment. Under the action of dry distillation and thermal decomposition, the sludge is converted into four substances: pyrolysis oil, water, non-condensable gas and pyrolysis residue (coke).

[0003] After the sludge is heat-treated, there will be gas with heat discharged. If this part of heat is not utilized, it will cause waste of heat. At present, heat exchange is used to heat water, but the water is in the water tank. When the water in the water tank is heated, it needs to be discharged and then replaced with new cold water, which will cause part of the heat to be dissipated and wasted. Therefore, this application proposes a waste heat recovery device for sludge collaborative waste incineration based on carbon neutralization. Summary of the Utility Model

[0006] A plurality of heat recovery components that can be connected;

[0007] The heat recovery component includes a delivery pipe, a sleeve is sleeved on the delivery pipe and is fixedly arranged in sealing connection with the delivery pipe, a water inlet pipe and a water outlet pipe are respectively installed at both ends of the sleeve, a first flow divider and a second flow divider are fixed in the delivery pipe, and the first flow divider and the second flow divider are arranged opposite to the sleeve.

[0008] Further, flange plates are installed at both ends of the delivery pipe, and the flange plates on two adjacent heat recovery components are connected by a connecting piece.

[0009] Further, the connecting piece is a bolt and a nut, and the bolt penetrates through the flange plate and engages with the nut to fix the two flange plates together.

[0019] The technical solutions in the present utility model will be further described below with reference to the drawings and embodiments.

[0020] As Figures 1-3 shown, an embodiment of the utility model provides a sludge collaborative waste incineration waste heat recovery device based on carbon neutralization, including:

[0021] A plurality of connectable waste heat recovery components 1, flange plates 4 are installed at both ends of the conveying pipe 2, and the flange plates 4 on two adjacent waste heat recovery components 1 are connected by a connecting member. The connecting member is a bolt and a nut, and the bolt passes through the flange plate 4 and meshes with the nut to fix the two flange plates 4 together.

[0022] The waste heat recovery component 1 includes a conveying pipe 2. A sleeve 5 which is hermetically connected to and fixedly arranged on the conveying pipe 2 is sleeved on the conveying pipe 2. The sleeve 5 and the conveying pipe 2 are coaxially arranged. A plurality of fixing rods 3 are fixed on the inner wall of the sleeve 5. The plurality of fixing rods 3 are distributed in an annular array on the inner wall of the sleeve 5. The moving water flow can be mixed by the fixing rods 3 so that the temperature of the heat-exchanged water is more uniform.

[0023] The water inlet pipe 6 and the water outlet pipe 7 are respectively installed at both ends of the sleeve 5. A first flow dividing member 8 and a second flow dividing member 9 are fixed in the conveying pipe 2. The first flow dividing member 8 and the second flow dividing member 9 are arranged opposite to the sleeve 5. Both the first flow dividing member 8 and the second flow dividing member 9 are triangular prisms. The edges of the first flow dividing member 8 and the second flow dividing member 9 facing the direction of the water outlet pipe 7 are vertically arranged, as Figure 3 shown.

[0024] During use, the gas with heat is conveyed inside a plurality of connected waste heat recovery components 1. The water inlet pipe 6 is connected to the water outlet end of an external water pump, and the water outlet pipe 7 can be connected to a water tank for collecting hot water;

[0025] Water enters the sleeve 5 through the water inlet pipe 6 and fills the sleeve 5. When the heat is conveyed through the conveying pipe 2, the water in the sleeve 5 can be heated through heat exchange. When the air passes through the first flow dividing member 8 and the second flow dividing member 9, the gas in the middle can be dispersed to both sides. In this way, the heat in the middle can be dispersed to both sides, so that the heat can be utilized more fully. The heat-exchanged clear water is discharged through the water outlet pipe 7. In this way, it avoids the disadvantage that in the prior art, when heat exchange is realized through a water tank, the heat cannot be fully utilized during the time of draining water and replacing clear water;

[0026] Since a plurality of waste heat recovery components 1 are connected in series, the heat can be gradually exchanged, so that the heat can be fully utilized.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
