Description

Technical Field

[0001] This utility model belongs to the field of printing and dyeing technology, and relates to a heat pipe type dye bath heater. Background Technology

[0002] The dyeing and printing industry generally uses centralized steam boilers for heating dyeing vats, and controls the heating temperature rise process through temperature control valves. This process generally suffers from problems such as high energy consumption, large investment, and short boiler lifespan. The main reason is that traditional boilers continuously supply water and evaporate, which leads to problems such as oxygen corrosion and scaling, causing irreparable boiler failures. At the same time, the steam system suffers from problems such as running, leaking, dripping, and seeping, resulting in low energy utilization efficiency.

[0003] To address this issue, a heat pipe type dye bath heater was designed to overcome the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a heat pipe dyeing bath heater that is simple and reasonable in structure, efficient and stable in operation, and practical and convenient.

[0005] This utility model is achieved through the following technical solution: a heat pipe type dyeing vat dyeing liquid heater, which includes a steam generator and a heat exchanger. A burner is installed on one side of the steam generator, and a flue gas outlet is opened on the opposite side of the burner. Multiple flue gas pipes are arranged between the burner and the flue gas outlet. A medium is filled in the steam generator outside the flue gas pipes. The upper part of the steam generator is connected to the heat exchanger, and the evaporated steam flows into the heat exchanger for heat exchange.

[0006] Preferably, the steam generator consists of an evaporation tube body, an inlet, and an outlet. Both the inlet and outlet are equipped with connecting flanges. The evaporation tube body is equipped with two baffles, which divide the evaporation tube body into independent sealed chambers. A pipe connected to the steam generator is arranged below the chamber. Multiple heat exchange pipes are opened between the two baffles in the chamber. The dye liquor enters from the inlet, is heated by the heat exchange pipes, and then flows out from the outlet.

[0007] Preferably, two pipes are arranged between the steam generator and the heat exchanger, one of which is a steam pipe and the other is a condensate recovery pipe. One end of each pipe is located near the inlet and outlet of the heat exchanger, respectively, and the other end of the condensate recovery pipe is directly connected to the bottom of the steam generator, while the steam pipe is connected to the top of the steam generator.

[0008] Preferably, the medium is water or a multi-component solution with water as the main component.

[0009] Preferably, the heat exchanger is made of stainless steel or titanium alloy, which is suitable for heating various media.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. The medium inside the heat pipe of this utility model can be water or a multi-component composite solution with water as the main component;

[0012] 2. In this invention, the burner heats the water medium on the primary side (inside the heat pipe) to evaporate. The water on the secondary side (outside the heat pipe) absorbs the latent heat of the water vapor from the primary side and heats up. The water condensed from the steam on the primary side is then reheated by combustion and turned into water vapor again.

[0013] 3. This utility model adopts a primary side vacuum seal. The height difference between the liquid level in the primary side channel and the liquid level in the generator ensures that the primary side circulation loop can still return to the generator when there is no water pump to provide power, thereby avoiding the entry of external oxidizing gases and causing oxidation corrosion, and extending the service life of the generator.

[0014] 4. In this invention, the same medium undergoes repeated evaporation and condensation physical changes on the primary side without replenishment, so the water quality will not change, scale will not form on the water side of the generator, and the service life of the generator will be extended.

[0015] 5. Even if scale forms on the water outside the heat pipe of this utility model, it will not affect the design life of the boiler. Only simple cleaning and maintenance of the heat pipe are needed to restore the heat exchange efficiency to the design.

[0016] 6. The heat exchanger of this utility model can be made of stainless steel or titanium alloy, and is suitable for heating various media.

[0017] 7. The coupled water-cooled premixed burner of this utility model controls the combustion chamber temperature, which can effectively reduce the thermal NOx generated by combustion and achieve the environmental protection effect of low nitrogen emission.

[0018] 8. The steam generator of this utility model has a small water capacity on the water side, resulting in a low risk of explosion. Attached Figure Description

A burner 14 is installed on one side of the steam generator 1, and a flue gas outlet 3 is opened on the opposite side of the burner 14. Multiple flue gas pipes 4 are arranged between the burner 14 and the flue gas outlet 3. A medium 15 is filled into the steam generator 1 outside the flue gas pipes 4. The upper part of the steam generator 1 is connected to the heat exchanger 2, and the evaporated steam flows into the heat exchanger 2 for heat exchange.

[0023] The steam generator 1 consists of an evaporation tube body 5, an inlet 6, and an outlet 7. Both the inlet 6 and the outlet 7 are equipped with connecting flanges 8.

The dye liquor enters from the inlet 6, is heated by the heat exchange pipes 11, and then flows out from the outlet 7.

[0024] This invention uses two partitions to divide the evaporator tube body into an independent sealed chamber, and multiple heat exchange pipes are opened in the chamber to ensure the normal use of the equipment.

[0025] Two pipes are arranged between the steam generator 1 and the heat exchanger 2. One pipe is a steam pipe 12, and the other is a condensate recovery pipe 13. One end of each pipe is located near the inlet 6 and outlet 7 of the heat exchanger 2, respectively. The other end of the condensate recovery pipe 13 is directly connected to the bottom of the steam generator 1, and the steam pipe 12 is connected to the top of the steam generator 1. The medium 15 is water or a multi-component solution with water as the main component. The heat exchanger 2 is made of stainless steel or titanium alloy and is suitable for heating various media. Of course, adjustments can be made according to actual conditions, and no limitations are imposed.

[0030] 4. In this invention, the same medium undergoes repeated evaporation and condensation physical changes on the primary side without replenishment, so the water quality will not change, scale will not form on the water side of the generator, and the service life of the generator will be extended.

[0031] 5. Even if scale forms on the water outside the heat pipe of this utility model, it will not affect the design life of the boiler. Only simple cleaning and maintenance of the heat pipe are needed to restore the heat exchange efficiency to the design.

[0034] 8. The steam generator of this utility model has a small water capacity on the water side, resulting in a low risk of explosion.

[0035] The working process of this utility model is as follows:

[0036] In this invention, the steam generator and heat exchanger are connected to form a separate heat pipe structure. The steam generator serves as the heating section, and the heat exchanger as the condensing section. The water side of the steam generator and the shell side of the heat exchanger form the primary side channel of the heat pipe. The fire side of the steam generator serves as the hot end of the secondary side of the heat pipe, and the tube side of the heat exchanger serves as the cold end of the secondary side. Heat exchange occurs through the media in the primary side channel and the media in the secondary side channel, achieving efficient heat transfer from the hot end to the cold end. The primary side circulation loop is vacuum sealed, and the lowest liquid level in the primary side channel is higher than the highest liquid level in the generator.
