Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of municipal heating, and in particular refers to a vibration reduction and noise reduction system for a heat exchange unit in a heat exchange station. Background Art
[0002] The heat exchange station is the connection place between the heat network and the heat user in the heating system. Its function is to transfer heat energy from the heat network to the heat user system, provide user needs, adjust the parameters of the heat medium transported by the heat network, transform them to the parameters and quantity required by the user's equipment, and control the user's optimal economic operation state. The heat exchange station is generally required to be set up in an independent building in the community. The heat exchange station is equipped with a heat exchange room, a duty room, a control room and a toilet, etc., and the required heat exchange station building area is large. With the development of urban centralized heating, especially in the old urban area, the original buildings are dense, and new independent heat exchange stations are not allowed, which affects the normal heating of users. In addition, when the heating equipment is running, the heating equipment and pipelines will produce large vibration and noise problems, that is, the heat exchange station of a general high-rise building is set in the basement, which affects the quality of life of the surrounding residents. The vibration and noise reduction method of the traditional heat exchange station is to lay a base made of channel steel at the bottom of the heat exchange unit, or to add a vibration absorber on a simple concrete foundation, and at the same time add sound-absorbing materials to the inner wall of the wall. This vibration and noise reduction method is too simple and has little effect.
[0003] In order to solve such technical problems, it is necessary to study a shock-absorbing and noise-reduction system for the heat exchanger units in the heat exchange station that has a simple structure, is easy to use, can isolate equipment from buildings, reduce vibration transmission, reduce noise propagation, and reduce the impact on residents around the heat exchange station. Utility Model Content
[0004] The utility model aims to at least solve the problem in the prior art that the noise reduction effect of the traditional heat exchange station is limited and the noise impact on the surrounding residents is inevitable.
[0005] The present invention provides a vibration reduction and noise reduction system for a heat exchange unit in a heat exchange station, which is achieved by the following specific technical means: a sand filling layer, a rubber sheet layer and a concrete layer are laid in sequence on the original basement concrete floor, and a plurality of shock absorbers are fixedly installed on the concrete layer, and a unit channel steel frame is placed on the plurality of shock absorbers, and the unit channel steel frame is used to fix the heat exchange unit, thereby forming a multiple vibration reduction effect.
[0006] Preferred technical solution 1: the sand filling layer is composed of a ring beam cast on a concrete bottom plate and fine sand filled in the ring beam, the rubber sheet layer is laid on the fine sand, and the ring beam and the concrete bottom plate are fixed by planting steel bars;
[0007] The ring beam is 150 mm wide and 300 mm high; the thickness of the fine sand is 130 mm.
[0008] Preferred technical solution 2: A plastic film is laid on the top surface of the fine sand.
[0009] Preferred technical solution three: the rubber sheet layer is made of rubber sheets spliced into a sheet with a thickness of 20 mm, and the rubber sheet is a rubber sheet with a texture on the surface.
[0010] Preferred technical solution four: A polystyrene board is fixedly provided around the rubber sheet layer, and the polystyrene board is located in the inner circle of the ring beam to separate the concrete layer from the ring beam. The polystyrene board has a thickness of 15 mm and a height of 150 mm.
[0011] Preferred technical solution five: the concrete layer is composed of concrete poured on the rubber sheet layer with a thickness of 150 mm, and bidirectional threaded steel bars are arranged in the concrete layer.
[0012] The above structure enables this solution to have the following beneficial effects:
[0013] 1. Multiple vibration reduction is adopted to achieve multiple defense shock reduction effects. It has a simple structure and is easy to use. It can effectively isolate equipment and buildings and reduce the transmission of vibration;
[0014] 2. The heat exchange unit excites a variety of waveforms in the rubber particles and the sand filling layer. The waveform conversion can better utilize the loss effect of the structure on the various waveforms. When the vibration wave in the structure encounters a sudden change in impedance, wave scattering and reflection will occur. The wave scattering consumes the energy of the vibration wave, and the wave reflection increases the distance the vibration wave travels in the structure, thereby increasing the loss of the vibration wave in the structure. The vibration of the vibration source equipment is transmitted to the concrete foundation through the shock absorber. The movement of a large number of solid particles in the equipment foundation and the sand filling layer will inevitably cause mutual friction and collision between the solid particles. The mutual friction and collision between the solid particles will generate heat energy and consume the energy of the system. Therefore, waveform conversion, wave scattering, wave reflection, and friction and collision of solid particles can increase the vibration reduction effect of the utility model.
