DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4, an embodiment provided by the present utility model: a waste heat collector for furfural production, comprising a first waste heat collection device 1 and a second waste heat collection device 2. The first waste heat collection device 1 is arranged on the second waste heat collection device 2, and the first waste heat collection device 1 and the second waste heat collection device 2 have the same structure. The first waste heat collection device 1 and the second waste heat collection device 2 both include a solenoid valve 3, a delivery pipe 4, a heat collection tank 6, a fixing plate 7, a connecting fixing plate 8, a connecting delivery pipe 10, a discharge pipe 12 and a temperature control valve 13. The connecting fixing plate 8 is fixedly connected to both ends of the heat collection tank 6, the fixing plate 7 is fixedly connected to the inner sides of both ends of the heat collection tank 6, the connecting delivery pipe 10 is fixedly connected to the middle of the upper end of the heat collection tank 6, the discharge pipe 12 is fixedly connected to the bottom of the heat collection tank 6, the temperature control valve 13 is installed on the discharge pipe 12, the delivery pipe 4 is fixedly connected to both sides of the heat collection tank 6, and the solenoid valve 3 is fixedly installed on the delivery pipe 4. By setting the first waste heat collection device 1 and the second waste heat collection device 2, continuous heat collection of steam can be achieved twice, so that the heat inside the high-temperature steam discharged during furfural production can be reasonably utilized, and the discharge speed and rate of the steam can be controlled, so that the steam can fully contact the cooling water.

[0019] Temperature sensors 5 are uniformly and fixedly installed on the heat collection tank 6 to play a role in temperature detection.

[0020] Spiral delivery pipes 11 are uniformly and fixedly installed inside the heat collection tank 6, which can play a role in uniform heat transfer.

[0021] The spiral delivery pipes 11 communicate with the inside of the connecting fixing plate 8, and the vertically distributed connecting fixing plates 8 communicate with the connecting delivery pipe 10 and the discharge pipe 12 respectively, which can achieve the effect of stable delivery.

[0022] An outer protective sleeve 9 is fixedly installed outside the connecting delivery pipe 10 to play a role in heat preservation.

[0023] A fixed connection is made between the discharge pipe 12 in the first waste heat collection device 1 and the connecting delivery pipe 10 in the second waste heat collection device 2, which can achieve continuous heat collection treatment.

[0024] Working principle: First, connect the connecting and conveying pipe 10 in the first waste heat collection device 1 to the steam conveying pipe, so that the discharged steam is conveyed through the connecting and conveying pipe 10 in the first waste heat collection device 1 to the inside of the connecting and fixing plate 8 and each spiral conveying pipe 11. Since each spiral conveying pipe 11 is evenly distributed in a spiral shape in the heat collection tank 6, the cold water stored in the heat collection tank 6 conveyed through the conveying pipe 4 can fully exchange heat with each spiral conveying pipe 11 for heat collection treatment, so that the temperature of the cold water conveyed in the heat collection tank 6 rises. When the temperature sensor 5 detects that the water body inside the heat collection tank 6 rises to the specified temperature, at this time, the electromagnetic valves 3 distributed on both sides of the heat collection tank 6 operate, so that the hot water in the heat collection tank 6 is discharged and cold water is replenished to realize continuous heat collection. By controlling the temperature control valve 13 in the first waste heat collection device 1, the steam discharge rate of the discharge pipe 12 in the first waste heat collection device 1 can be controlled, so that the steam in the first waste heat collection device 1 can fully stay and exchange heat with the water body in the heat collection tank 6 to realize heat collection, and the waste heat carried in the steam discharged from the first waste heat collection device 1 can be fully utilized by the cold water inside the heat collection tank 6 in the second waste heat collection device 2. Therefore, this device can continuously realize two-stage heat collection and make full use of the heat.
