Description

Technical Field

[0001] This utility model belongs to the field of waste heat recovery and utilization technology, and in particular relates to a high-efficiency heat energy recovery and voltage stabilization system. Background Technology

[0002] Traditional waste heat recovery and utilization technologies generally fall into three categories: waste heat cascade utilization, waste heat refrigeration, and waste heat power generation.

[0003] Waste heat cascade utilization is suitable for processes with suitable waste heat cascade utilization, such as factories that need hot water for workers' bathing and daily use or processes that require hot water for cleaning. Waste heat refrigeration is suitable for hotels and other enterprises that can use cold water. Waste heat power generation is suitable for enterprises with a large amount of waste heat, such as steel mills and paper mills. However, for enterprises with scattered waste heat emission points, little waste heat (insufficient to drive generators), and no need for refrigeration or hot water, such as pharmaceuticals, food processing, and bottle labeling production lines, these enterprises cannot use the traditional three methods to recover waste heat.

[0004] To address these issues, we offer a high-efficiency heat recovery and voltage stabilization system. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency heat energy recovery and pressure stabilization system. By combining a steam compression component and a steam regeneration component, it solves the problem that existing waste heat recovery and utilization systems cannot stabilize the output of steam and have a low recovery and utilization rate.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a high-efficiency heat energy recovery and pressure stabilization system, comprising an outer frame. Support pads are fixedly connected to both sides of the bottom of the inner cavity of the outer frame. A heat energy conversion chamber is fixedly connected to the top of the support pads. An air inlet is provided on one side of the heat energy conversion chamber. A steam regeneration assembly is provided on the back of the heat energy conversion chamber. A steam compression assembly is provided on one side of the top of the inner cavity of the outer frame. The steam regeneration assembly includes a heat-conducting shell, the front of which extends through the inner cavity of the heat energy conversion chamber. A steam chamber is provided on the back of the heat-conducting shell. The steam compression assembly includes a steam compressor. The bottom of the steam compressor is fixedly connected to the top of the inner cavity of the outer frame via a mounting base. A steam pipe is provided on one side of the steam compressor, with the end of the steam pipe away from the steam compressor connected to the top of the steam chamber. An exhaust pipe is provided on the other side of the steam compressor, and a pressure valve is provided inside the exhaust pipe.

[0008] The present invention is further configured such that a support plate is fixedly connected to one side of the inner cavity of the outer frame, and a control box is fixedly connected to the top of the support plate. The control box can control the steam compressor to provide feedback compensation for the output steam pressure in a timely manner based on the real-time monitoring of the discharged steam pressure by the pressure valve.

[0009] The present invention is further configured such that mounting plates are fixedly connected to the top and bottom of both sides of the heat-conducting shell, and mounting screws are provided on the surface of the mounting plates. After the mounting screws are turned until one end passes through the mounting hole on the surface of the mounting plate, they are screwed into the screw holes on the surface of the heat energy conversion chamber and the steam chamber, thereby fixing the heat-conducting shell between the heat energy conversion chamber and the steam chamber, and facilitating disassembly later.

[0010] The present invention is further configured such that a water inlet pipe is provided on the top of the steam chamber, and an installation plate is provided on the top of the water inlet pipe. The installation plate provided on one end of the water inlet pipe enables the water inlet pipe to be connected to an external water tank for convenient real-time water supply.

[0011] The present invention is further configured such that a guide plate is provided in the inner cavity of the heat energy conversion chamber, and the back of the guide plate is in contact with the surface of the heat-conducting shell. The design of the guide plate can guide the flow path of waste heat steam in the inner cavity of the heat energy conversion chamber and improve the waste heat utilization efficiency.

[0012] The present invention is further provided that the back of the steam chamber is provided with a drain port, and the inner cavity of the drain port is provided with a sealing plug. By removing the sealing plug of the inner cavity of the drain port, the hot water in the inner cavity of the steam chamber can be discharged.

[0013] The present invention is further configured such that an insulation sleeve is fitted over the surface of the air inlet. The insulation sleeve is made of rubber and plastic insulation material, which is soft and flexible. When wrapped around the surface of the air inlet, it can reduce the heat loss of waste heat steam.

[0014] The present invention is further provided that the bottom of the heat energy conversion chamber is provided with a drain outlet, and the inner cavity of the drain outlet is provided with a solenoid valve, so that the drain outlet can discharge water droplets and non-condensable gases left after the waste heat steam in the inner cavity of the heat energy conversion chamber is released in real time.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model introduces waste heat steam into the heat energy conversion chamber and utilizes a special channel designed with a guide plate to enable the waste heat steam to quickly transfer heat to the water film on the other side of the heat-conducting shell metal film, causing the water film to evaporate instantly and form low-pressure clean steam, thus achieving efficient recovery of waste heat. The steam compressor recovers the clean steam, pressurizes and heats it, improves its heat energy quality, and reuses it in the steam heating equipment, effectively reducing energy waste.

The controller can control the steam compressor to provide feedback compensation for the output steam pressure in a timely manner based on the monitored pressure data, so as to ensure the stability of the steam pressure in the system. At the same time, the water in the steam chamber is replenished in real time through the water inlet pipe, and the hot water can be discharged through the drain port for use, thus ensuring the continuous and stable operation of the system.
