Description

Technical Field

[0001] This utility model relates to the field of heater technology, and in particular to a heater condensate circulation and recovery system device. Background Technology

[0002] In waste treatment, both dry waste and pyrolysis waste require heaters. These heating devices typically employ indirect heating, introducing water into the heater's inlet and heating it into steam or hot water. This high-temperature steam or hot water acts as a heat medium, transferring heat to the waste through a heat exchanger. The condensate produced during heat exchange is discharged through the heater's condensate drain. In existing technology, the condensate from the heater is discharged into a storage tank via the heater's condensate drain. Once the tank reaches a certain level, it is then pumped out. Since the condensate from the heater is usually desalinated water that has undergone internal demineralization, its quality is relatively good. Directly discharging it wastes water resources and loses its thermal energy. Therefore, this invention proposes a heater condensate recycling system that recirculates the condensate back into the heater, avoiding waste of water resources and thermal energy.

[0005] Furthermore, the top of the fixing seat is symmetrically provided with support rods on both sides of the arc-shaped groove, and the U-shaped water seal pipe is bound to the support rods by fixing clamps and bolts.

[0006] Furthermore, the fixing clamp includes two clamp bodies that are hinged to each other, and a connecting plate is provided at the outer end of the clamp body. The two clamp bodies wrap around the U-shaped water seal pipe, and the connecting plate is locked to the support rod by bolts.

[0007] Furthermore, elastic pads are provided at the bottom and sidewalls of the arc-shaped groove.

[0012] Beneficial effects

[0013] Compared to existing technologies, this utility model has at least the following advantages: The condensate from the heater is discharged from the condensate outlet, sent through a water supply pipe to a series-connected U-shaped water seal pipe, and then filtered before being circulated back into the heater inlet to participate in the next round of heating. This fully utilizes the residual heat of the condensate, reduces the energy required for the heater to heat the water to the set temperature, improves energy efficiency, and achieves the recovery and utilization of condensate heat and water resources. The filter improves the quality of the condensate, preventing it from adversely affecting the heater. The combination of the fixing base, support rod, and fixing clamps secures and supports the U-shaped water seal pipe, ensuring stable installation, reducing the risk of condensate leakage, and avoiding affecting the stability of the condensate flow.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] See Figures 1-4 This embodiment provides a heater condensate circulation and recovery system, including a water seal device 4. The input end of the water seal device 4 is connected to a water supply pipe 3, and the water supply pipe 3 is connected to the condensate outlet pipe 2 of the heater 1. The output end of the water seal device 4 is connected to a filter 8 through an outlet pipe 7. The filter 8 is connected to the inlet of the heater 1 through a circulation pipe 11 and a T-junction. The outlet pipe 7 is equipped with a valve 9 for cutting off the water flow during maintenance and repair of the heater or the condensate circulation pipeline. The circulation pipe 11 is equipped with an automatic pressure regulating valve 10, which can control the pressure of condensate entering the T-junction mixing point to avoid excessively high or low condensate pressure affecting the heater.

[0023] The water seal device 4 includes a fixed base 40, the top surface of which is provided with two or more arc-shaped grooves 41. Elastic pads are provided on the bottom and sidewalls of each arc-shaped groove 41. U-shaped water seal pipes 44 are inserted into the arc-shaped grooves 41, and these U-shaped water seal pipes 44 are connected in series via connecting pipes 45. The connecting pipes 45 are connected to an exhaust pipe, which is equipped with an exhaust valve to discharge gas accumulated in the U-shaped water seal pipes 44, preventing interference with the normal flow of condensate. Support rods 42 are symmetrically arranged on both sides of the arc-shaped grooves 41 at the top of the fixed base 40. The U-shaped water seal pipes 44 are bound to the support rods 42 by fixing clamps 43 and bolts. Specifically, the fixing clamps 43 include two interlocking arc-shaped clamp bodies 430. A connecting plate 431 is provided at the outer end of each clamp body 430, and a protective pad made of elastic material is provided on the inner sidewall of each clamp body 430. During installation, the two clamps 430 wrap around the U-shaped water seal pipe 44, and the connecting plate is locked onto the support rod 42 by bolts.

[0024] It should be noted that, in this embodiment, during installation, the position and height difference between the heater and the U-shaped water seal pipe are adjusted to create a pressure difference sufficient to allow the condensate to flow smoothly back to the heater inlet. Preferably, a circulation pump can be installed on the outlet pipe 7 to provide additional power, increase the flow rate and volume of the condensate, and ensure normal circulation of the condensate.

[0025] The interior of the fixing base 40 is hollow, and an injection port is provided at the top for injecting filling material into the fixing base. The filling material can be sand or water.

[0026] In this embodiment, filter 1 has multiple layers of filter screens, including a coarse filter screen, a fine filter screen, and an activated carbon filter screen, which are used to filter large particulate solid impurities, small particles and suspended solids, and adsorb harmful substances, respectively. The filter 8 improves the quality of condensate water, preventing scale buildup in the heater 1 when it is circulated back into the heater 1, thus reducing corrosion of the heater.

[0027] In practice, the condensate from the heater is discharged from the condensate outlet 2 and sent to the U-shaped water seal pipe in series via the water supply pipe. Then, the condensate is circulated through the filter and sent back to the heater inlet to participate in the next round of heating. This fully utilizes the residual heat of the condensate itself, reduces the energy required for the heater to heat the water to the set temperature, improves energy efficiency, and realizes the recovery and utilization of the heat of the condensate and water resources.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
