Description

Technical Field

[0001] The present invention belongs to a waste heat recycling device, in particular to a waste heat recycling device for a carbon anode calcination workshop. Background Art

[0002] The pot-type calciner is one of the main devices in carbon production. The existing cooling device for the calcined coke after the pot-type calciner usually uses circulating water to cool the water jacket. The existing cooling water jacket of the calciner has the following defects. First, a large amount of circulating water is required for the cooling water jacket. If all desalted water is used, precious water resources are discharged into the atmosphere in the form of water vapor through the cooling tower, and a large amount of heat is discharged into nature through the cooling tower, resulting in a waste. Second, if untreated water resources are used, scale will be generated on the inner wall of the water jacket due to the heating of the cooling water, reducing the heat transfer effect and service life. The service life of the existing water jacket is about 3 years.

[0003] How to conveniently realize the waste heat recovery of the lower water jacket of the pot-type calciner, improve the service life of the waste heat equipment for the calcined coke after the pot-type calciner, reduce the consumption of cooling water, save water resources, and how to recycle the waste heat are problems that need to be solved. Utility Model Content

[0004] The technical problem to be solved by this application is: to provide a waste heat recycling device for a carbon anode calcination workshop. Using this device can improve the service life of the lower water jacket, save water resources, and recycle waste heat for reuse. It can reduce production costs and save social energy during operation.

[0005] To achieve the above object, the present utility model provides the following technical solution: A device for heating bath water with the waste heat of a calciner, including a waste heat extraction device and a waste heat utilization device. The waste heat extraction device consists of a lower water jacket of the calciner, a circulating water pump, and a hot water tank. Among them, multiple groups of lower water jackets of the calciner are connected to the circulating water pump through pipelines to transport hot water to the hot water tank;

[0006] The waste heat utilization device consists of a heating pump, a main pipe of the tap water pipeline, a heat exchanger, and a hot water storage tank. The hot water tank is connected to one end of the heat exchanger through the heating pump, and the other end of the heat exchanger is connected to the hot water tank;

[0007] The main pipe of the tap water pipeline and the hot water storage tank are both connected to the heat exchanger.

[0008] The beneficial effects of this application are:

[0009] 1. The device adopts a closed cycle, reducing water evaporation and saving water resources.

[0010] 2. The cooling water used for cooling the water jacket is desalted water, which does not scale during operation, reduces burnout, and can improve the service life of the lower water jacket.

[0011] 3. Send the heated softened water to the bath heat exchanger to heat the tap water, achieving the recycling and reuse of waste heat. Description of the Drawings

[0014] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model. The experimental methods in the following embodiments are all conventional methods unless otherwise specified. The materials, reagents, etc. used in the following embodiments can be obtained from commercial channels unless otherwise specified.

[0015] Embodiment 1:

[0016] As Figure 1 shown, a device for heating bath water with waste heat of a calciner is divided into two parts. The first part is waste heat extraction equipment, which consists of 72 water-saving jackets 1 under the calciner, two circulating water pumps 2, and one hot water tank 3.

[0017] The demineralized water generated by 72 water-saving jackets 1 under the calciner is transported to the hot water tank 3 through two circulating water pumps 2. The demineralized water continuously circulates in the waste heat extraction equipment, causing the demineralized water to continuously heat up until it reaches 80 degrees Celsius.

[0018] The second part is waste heat utilization equipment, which consists of a hot water tank 3, two heating pumps 4, a main pipe 5 of the tap water pipeline, one bath heat exchanger 6, and one hot water storage tank 7.

[0019] The 80-degree Celsius demineralized water in the hot water tank 3 is transported to the bath heat exchanger 6 through two heating pumps 4 at a constant flow rate. The hot water cooled by the bath heat exchanger 6 then returns to the hot water tank 3, forming a closed-loop system.

[0020] The tap water from the main pipe 5 of the tap water pipeline enters the bath heat exchanger 6 and is heated in the bath heat exchanger 6. When the normal-temperature tap water is heated to the set 50 degrees Celsius, the outlet valve at the tap water end of the heat exchanger 6 is opened, allowing it to flow into the hot water storage tank 7 for the company's employees to take baths.

[0021] Although embodiments of the present utility model have been shown and described, the specific embodiments are merely explanations of the present utility model and do not limit the utility model. The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
