Description
Technical Field
[0001] The utility model relates to a heating device for a waste heat recovery ice-making device, belonging to the technical field of waste heat recovery. Background Art
[0002] In coastal areas, after going out to sea to fish, fishermen will store the harvested fish in the ship's own cold storage for freezing in order to keep it fresh. However, the ship's cold storage requires an electric system to operate, which results in a high operating cost for the ship's cold storage. With the development of technology, devices that use exhaust gas and waste heat for refrigeration have appeared in the industry. The above-mentioned refrigeration devices use exhaust gas and waste heat as the driving source to achieve refrigeration through ammonia absorption refrigeration, so that the heat of exhaust gas and waste gas can be effectively reused. During the operation of the engine on the fishing boat, high-temperature flue gas will be emitted. Collecting this high-temperature flue gas as a driving source to achieve refrigeration through ammonia absorption refrigeration can not only save costs, but also improve energy utilization, and can significantly increase economic and social benefits.
[0003] The existing fishing vessel smoke ice making device may have the following problems during actual use:
[0004] 1: When a fishing boat is just started, the exhaust gas temperature is relatively low for a period of time.
[0005] 2: When a fishing boat is operating at sea for a long time, the engine is running at a low speed and the exhaust gas temperature is also low.
[0006] Low-temperature flue gas cannot be used as a driving source for refrigeration, which results in a poor refrigeration effect in the cold storage. In view of the above problems, the industry needs a heating device for waste heat recovery and ice-making devices to solve the problems faced by the industry. Summary of the invention
[0007] The technical problem to be solved by the utility model is to provide a heating device for a waste heat recovery ice-making device to solve the problems faced in the industry.
[0008] In order to solve the above technical problems, the utility model is implemented through the following technical solutions: a heating device for a waste heat recovery ice-making device, comprising an ammonia water generator, an electric three-way valve for passing waste heat, a gas-liquid separator, a condenser, a cold liquid storage tank, a supercooler, an ice maker, an absorber, a concentrated solution tank, and a solution heat exchanger. A heating device is arranged between the ammonia water generator and the electric three-way valve. The heating device comprises a heating box, a plurality of heating holes are arranged on the top of the heating box, a plurality of insertion slots are arranged on the bottom of the heating box, an electric heating rod is arranged in the heating hole, a plurality of upper insulation boards are arranged on the top of the inner side of the heating box, the upper insulation boards are spaced apart and distributed between the electric heating rods, and a movable structure is arranged on the outer bottom of the heating box.
[0009] Preferably, the movable structure includes a fixed frame with a U-shaped structure, an insertion cylinder is arranged on the fixed frame, an intermediate support plate is arranged on the cylinder shaft of the insertion cylinder, a plurality of lower heat insulation plates are arranged on the intermediate support plate, and the lower heat insulation plates are inserted into the insertion grooves.

[0014] Compared with the prior art, the utility model has the following advantages: the temperature of the incoming flue gas is measured by a temperature sensor, and then the position of the movable structure is adjusted according to the result of the temperature measurement. When the temperature of the flue gas reaches the set value, the cylinder is inserted to drive the lower insulation board down to speed up the flow of the flue gas. When the temperature of the flue gas does not reach the set value, the cylinder is inserted to drive the lower insulation board up to form an S-shaped channel between the upper insulation board and the lower insulation board, and at the same time, the electric heating rod is started for heating to increase the heating area of the flue gas and increase the temperature of the flue gas.

DETAILED DESCRIPTION
[0022] The utility model is described in detail below with reference to the accompanying drawings and specific implementation methods:
[0023] like Figures 1 to 5 A heating device for a waste heat recovery ice-making device shown in the figure comprises an ammonia water generator 1, an electric three-way valve 2 for passing waste heat, a gas-liquid separator 3, a condenser 4, a cold liquid storage tank 5, a supercooler 6, an ice maker 7, an absorber 8, a concentrated solution tank 9, and a solution heat exchanger 10. A heating device 11 is arranged between the ammonia water generator 1 and the electric three-way valve 2. The heating device 11 comprises a heating box 1101, a plurality of heating holes 1102 are arranged above the heating box 1101, a plurality of insertion grooves 1103 are arranged below the heating box 1101, an electric heating rod 1104 is arranged in the heating hole 1102, a plurality of upper insulation boards 1105 are arranged above the inner side of the heating box 1101, and the upper insulation boards 1105 are spaced and distributed between the electric heating rods 1104. A movable structure 12 is arranged at the outer bottom of the heating box 1101.
[0024] In order to be able to adjust the flow path of the smoke, the movable structure 12 further includes a fixed frame 1201 with a U-shaped structure, an insertion cylinder 1202 is arranged on the fixed frame 1201, an intermediate support plate 1203 is arranged on the cylinder axis of the insertion cylinder 1202, a plurality of lower heat insulation plates 1204 are arranged on the intermediate support plate 1203, and the lower heat insulation plates 1204 are inserted into the insertion grooves 1103.
[0025] In order to achieve air intake and exhaust, an air intake pipe 1106 and an air outlet pipe 1107 are further provided on the right side and the left side of the heating box 1101 respectively.
[0026] In order to detect the temperature of the smoke, further, a temperature sensor 13 is provided in the air inlet pipe 1106 and the air outlet pipe 1107 , and the heating box 1101 is provided with a plurality of temperature sensors 13 .
[0027] In order to allow the smoke to circulate in an S-shape, the upper insulation plates 1105 are of different lengths and are spaced apart from each other.
[0028] When in use, the flue gas is introduced into the heating box 1101 through the air inlet pipe 1106, and a temperature sensor 13 is arranged on the air inlet pipe 1106. The temperature sensor 13 measures the temperature of the flue gas in the air inlet pipe 1106.

If it does not reach the set value, the number of electric heating rods 1104 used is adjusted to increase the heating value, so as to achieve the purpose of heating the smoke.
