Description
技术领域technical field
本实用新型涉及一种气体余热利用装置，尤其涉及一种适用于气体发电机组排出排气中热量的回收利用装置。The utility model relates to a gas waste heat utilization device, in particular to a recovery and utilization device suitable for the heat in exhaust gas discharged by a gas generating set.
背景技术Background technique
气体发电机组尤其是沼气发电机组近年来发展迅速，国家出台政策支持养殖场、污水处理厂等建设沼气工程。传统的发电机组很少采用排气余热利用系统，这样排气带走的热量直接散发到大气中，既影响了环境温度，又不利于能量的综合利用。在大型气体发电机组中有的采用了排气余热回收利用，但是其结构复杂，成本较高。Gas generator sets, especially biogas generator sets, have developed rapidly in recent years, and the state has issued policies to support the construction of biogas projects in farms and sewage treatment plants. Traditional generator sets seldom use exhaust waste heat utilization system, so that the heat taken away by the exhaust is directly dissipated into the atmosphere, which not only affects the ambient temperature, but also is not conducive to the comprehensive utilization of energy. Some of the large-scale gas generating units adopt exhaust waste heat recovery and utilization, but its structure is complicated and the cost is high.
气体发电机组尤其是沼气发电机组一般气体燃烧发出的热量分为三部分，三分之一左右热量通过气体发电机组转化成电能；约三分之一热量由冷却水循环带走；另外大约三分之一的热量随着排放的废气散发掉。而在许多养殖场一方面需要电能，另一方面还需要热能供养殖场某些场所使用，如果气体发电机组的排气热量不进行回收利用，而直接排放到空气中，而在需要热量的场所就必须燃烧其它燃料单独提供热量，这就必然造成能源的浪费，同时会将大量的CO2排放到空气中，有悖于国家号召的节能减排和可持续发展。Gas generator sets, especially biogas generator sets, generally generate heat from gas combustion into three parts. About one-third of the heat is converted into electrical energy through the gas generator set; about one-third of the heat is taken away by the cooling water cycle; the other about one-third One's heat is dissipated with the exhaust gas. On the one hand, many farms need electric energy, and on the other hand, they also need heat energy for some places in the farm. If the exhaust heat of the gas generator set is not recycled, it is directly discharged into the air, and in places that need heat It is necessary to burn other fuels to provide heat alone, which will inevitably cause a waste of energy, and will emit a large amount of CO2 into the air at the same time, which is contrary to the energy conservation and emission reduction and sustainable development called by the state.
