Description

Technical Field

[0001] This utility model relates to the technical field of heat recovery, specifically to a flash evaporation device for steam condensation heat recovery in textile printing and dyeing equipment. Background Technology

[0002] In the textile industry, steam dryers are mainly used for drying and fixing the color of textile fabrics. Steam is introduced into the drum, and the heat of the steam is transferred to the fabric outside the drum. After being heated, the moisture in the fabric evaporates into the flowing air outside the drum and is discharged with the hot air flow or dehumidification air flow.

[0003] For example, Chinese utility model patent CN206930183U discloses a flash steam heat recovery device for condensate, comprising a condensate tank and a storage tank. The condensate tank is equipped with an exhaust pipe connected to the atmosphere. The upper end of the storage tank has a connection port into which the outlet end of the exhaust pipe can be inserted. The storage tank has a cold water inlet and an overflow port. The overflow port is connected to an overflow pipe, and the cold water inlet is connected to a cold water inlet pipe. The lower end of the storage tank is also equipped with a temperature sensor for detecting the temperature of the liquid in the storage pipe. A control valve connected to the temperature sensor via an electrical signal is installed on the cold water inlet pipe. This utility model can meet the heat recovery requirements of a large amount of condensate, saving energy and protecting the environment.

[0004] Since the steam introduced into the drum liquefies into condensate and is discharged, the condensate contains a large amount of waste heat. The condensate tank is usually an atmospheric pressure tank that is directly connected to the atmosphere, which will cause flash evaporation. The flash steam evaporates into the atmosphere, causing heat loss. In order to achieve energy conservation and emission reduction, it is necessary to recover the waste heat from the wet and hot exhaust gas and condensate. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a flash evaporation device for steam condensation heat recovery in textile printing and dyeing equipment, which effectively recovers and reuses the heat of water condensed from the steam generated in textiles, avoids heat waste, and improves practicality.

[0006] This utility model discloses a steam condensation heat recovery flash evaporation device for textile printing and dyeing equipment. It includes a heat collection chamber with a feed pipe connected to its top. A heat recovery mechanism is installed inside the heat collection chamber. The heat recovery mechanism includes a base plate fixedly installed in the bottom area inside the heat collection chamber. A mixing chamber is fixedly installed at the top of the base plate, and a top plate is fixedly installed at the top of the mixing chamber. Multiple conveying pipes are longitudinally fixedly installed on the top plate, with their top ends located on the upper side of the top plate and their bottom ends on the lower side of the base plate. Multiple first drain pipes are connected to the bottom of the mixing chamber, each equipped with a valve. A second drain pipe is connected to the outer wall of the heat collection chamber, with its bottom end located between the heat collection chamber and the mixing chamber. A motor is fixedly installed at the bottom of the heat collection chamber, and a rotating shaft is longitudinally fixedly installed at the motor's output end. The rotating shaft is rotatably connected to the middle areas of the heat collection chamber, the base plate, and the mixing chamber. Multiple... The mixing chamber has a water inlet pipe obliquely connected to the top area of ​​the outer wall of the mixing chamber. The top of the water inlet pipe is located outside the heat collection chamber. Each mixing blade is located inside the enclosure of each conveying pipe. This textile printing and dyeing equipment's steam condensation heat recovery flash evaporation device discharges condensate into the heat collection chamber through the feed pipe and water that needs to be heated into the mixing chamber through the water inlet pipe. The water discharged into the feed pipe is then discharged into the bottom area of ​​the heat collection chamber through the conveying pipe, heating the water inside the mixing chamber. The water in the bottom area of ​​the heat collection chamber also heats the bottom area of ​​the mixing chamber. The motor is started, and the motor outputs power to synchronously drive the rotating shaft and mixing blades to rotate, thereby stirring the water that needs to be heated inside the mixing chamber. This accelerates the heating efficiency of the water inside the mixing chamber and effectively recovers and reuses the heat from the condensed water generated by textile production, avoiding heat waste and improving practicality.

[0007] Preferably, multiple through holes are provided on the outer side wall of the base plate. By providing through holes, when the water in the bottom area of ​​the heat collection chamber is about to exceed the base plate, the water will spread to the space between the inner side wall of the heat collection chamber and the outer side wall of the mixing chamber, thereby providing insulation for the water inside the mixing chamber.

[0008] Preferably, each of the first drain pipes has an extension pipe installed laterally at its bottom end. Each extension pipe is fixedly installed at the bottom end of the heat collection chamber by a bracket. By installing the extension pipe, it is convenient to guide the heated water and facilitate the collection of the water.

[0009] Preferably, a first guide seat is fixedly installed at the top of the top plate. By installing the first guide seat, it is convenient to guide the condensate water discharged into the top area of ​​the heat collection chamber through the feed pipe.

[0010] Preferably, a water level gauge is fixedly installed on the outer wall of the heat collection chamber, which facilitates the detection of the water level between the heat collection chamber and the mixing chamber.

[0011] Preferably, a thermometer is obliquely fixed on the outer wall of the heat collection chamber, with the bottom end of the thermometer located in the bottom area inside the mixing chamber. By installing the thermometer, it is convenient to observe the temperature of the heated water inside the mixing chamber.

[0012] Preferably, a second guide seat is fixedly installed at the bottom of the heat collection chamber. By installing the second guide seat, it is convenient to buffer the water drained from the bottom area of ​​the conveying pipe.

[0013] Preferably, each of the conveying pipes is connected to a guide ring at its top end. By installing the guide ring, it is convenient to guide the condensate discharged into the heat collection chamber through the feed pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The steam condensation heat recovery flash evaporation device for textile printing and dyeing equipment discharges condensate into the heat collection chamber through the feed pipe, and discharges water to be heated into the mixing chamber through the water inlet pipe. The water discharged into the feed pipe is then discharged into the bottom area of ​​the heat collection chamber through the conveying pipe. The water in the conveying pipe heats the water in the mixing chamber, and the water in the bottom area of ​​the heat collection chamber heats the bottom area of ​​the mixing chamber. The motor is started, and the motor outputs power to synchronously drive the rotating shaft and stirring blades to rotate, thereby stirring the water to be heated in the mixing chamber. This accelerates the heating efficiency of the water in the mixing chamber, effectively recovering and reusing the heat from the condensed water generated by textile printing, avoiding heat waste and improving practicality.
