Description

Technical Field

[0001] This utility model relates to the field of boiler steam recovery technology, specifically a boiler steam condensate recovery device. Background Technology

[0002] Steam releases its latent heat of vaporization in steam-using equipment, turning into condensate, which is then discharged through a steam trap. Condensate from different steam-using equipment is collected in a collection tank via a recovery network and then sent to the boiler or other heat-using applications by a condensate recovery device. The boiler steam condensate recovery device (hereinafter referred to as the "recovery device") is an important energy-saving and water resource recovery device in industrial boiler systems. With rising energy prices and increasingly stringent environmental regulations, boiler steam condensate recovery technology is being used more and more widely. Recovering condensate not only reduces boiler operating energy consumption and water treatment costs but also reduces negative environmental impacts and improves the sustainability of industrial production.

[0003] The existing technology has the following shortcomings: The existing technology disclosed in CN201921395603.0 is a boiler steam condensate recovery device, which includes a boiler body and a return box. The boiler body and the return box are connected to an outlet pipe and a return pipe. The outlet pipe and the return pipe are both U-shaped pipe structures, with one end connected to the top of the boiler body. The other end of the outlet pipe is inserted into the interior of the return box, and the other end of the return pipe is connected to the top of the return box. A secondary heating device is connected inside the return box, and the return pipe and the outlet pipe are connected to a condensation device.

[0004] While the aforementioned equipment can conveniently condense and recover steam during use, its condensation mechanism is relatively simple and straightforward, resulting in a relatively poor steam condensation effect. It is difficult to cool and condense the steam quickly, making it inconvenient for efficient operation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a boiler steam condensate recovery device to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a boiler steam condensate recovery device, comprising a boiler body, an exhaust pipe fixedly connected to the top of the boiler body, a condensate box provided on one side of the boiler body, a first water pump fixedly installed on one side of the condensate box, a water guide pipe fixedly connected to the first water pump, and a water storage tank fixedly installed at the bottom of the condensate box.

[0007] In a preferred embodiment of this invention, the boiler body is connected to the condenser box via an exhaust pipe.

[0008] As a preferred embodiment of this utility model, the condenser includes a water inlet, a condenser tube, and a heat sink. The condenser has a water inlet at the top and a condenser tube inside. The condenser tube has a heat sink on it and there are multiple condenser tubes. The condenser tube is connected to an exhaust pipe.

[0009] As a preferred embodiment of this utility model, a plurality of heat sinks are provided and symmetrically distributed outside the condenser tube, and both the heat sinks and the condenser tube are made of aluminum alloy.

[0010] As a preferred embodiment of this utility model, the first water pump is fixedly installed on one side of the condenser box by bolts, and the first water pump is connected to the boiler body through a water guide pipe.

[0011] As a preferred embodiment of this utility model, the water storage tank includes a drain pipe, a filter screen, a water level sensor, a controller, a slag discharge port, a second water pump, and a return pipe. The drain pipe and the filter screen are installed inside the water storage tank. The water level sensor is fixedly installed on the inner wall of the water storage tank, and the controller is fixedly installed on the outer wall of the water storage tank. A slag discharge port is provided on one side of the water storage tank, and the second water pump is fixedly installed on the outer wall of the water storage tank. A return pipe is fixedly connected to the second water pump. The drain pipe is connected to the condenser pipe and extends through the filter screen to the bottom of the water storage tank.

[0012] In a preferred embodiment of this invention, the water level sensor and the second water pump are both electrically connected to the controller via wires, and the second water pump is connected to the condenser via a return pipe.

[0013] Compared with the prior art, the present invention provides a boiler steam condensate recovery device, which has the following beneficial effects:

[0014] 1. This boiler steam condensate recovery device uses an exhaust pipe, a condensation tank, a water inlet, and condensing pipes in combination. The cold water inside the condensation tank can quickly condense and exchange heat with the steam discharged from the boiler body. By setting multiple condensing pipes to divert the steam, and by setting several heat dissipation fins on the condensing pipes, the condensation and heat exchange efficiency of the steam can be effectively improved, facilitating its complete condensation and liquefaction. By setting a first water pump and a water guide pipe, the heated cold water inside the condensation tank can be introduced into the boiler body, which can replenish water resources, reduce heating time and save fuel, and facilitate better operation.

[0015] 2. This boiler steam condensate recovery device, through the coordinated use of a water storage tank, drain pipe, water level sensor, controller, second water pump, and return pipe, facilitates the collection of condensate after steam condensation. When the water level reaches a predetermined value, the water level sensor sends a signal to the controller, which then activates the second water pump to guide the cold water from the storage tank into the condensate tank via the return pipe, facilitating recycling and preventing water waste. The device also incorporates a filter screen and a drain outlet, with the drain pipe extending through the filter screen to the bottom of the storage tank, effectively filtering impurities in the condensate and facilitating the removal and cleaning of these impurities. This enhances the condensate's structural practicality and functionality. Attached Figure Description
