The boiler waste gas energy recovery and utilization system provides powerful waste gas treatment and ensures that exhaust gases reach the standard. The Stirling engine is adopted in the boiler waste gas energy recovery and utilization system, so energy exchange efficiency is high; a heat accumulator is arranged between the heater and the cooler, in general effective heat efficiency can reach 25%-35%, particle dust is fully removed, the particle content in waste gas is reduced, atmosphere is protected, oxynitrides and the like in the waste gas are removed, and the environment is protected; the boiler waste gas energy recovery and utilization system operates stably, is little in noise, meanwhile weakens noise pollution when the waste gas is exhausted, and is easy to maintain; because the internal structure is closed, lubricating oil is not used, scale deposits and dirt deposits are not generated, and the boiler waste gas energy recovery and utilization system is easy to maintain, operate and manage.
Description
Technical field
The utility model relates to a kind of exhaust energy recovery and utilizes system, relates in particular to a kind of boiler waste gas energy and reclaims and utilize system.
Background technology
In the energy expenditure of various boilers, waste gas residual heat accounts for 15%～27%, does not discharge on the spot if waste gas adds utilization, is the waste resource so, also is contaminated environment.The using waste heat from tail gas aboundresources of China's medium small boiler, the potentiality of recycling are very big, and since " eight or five ", energy markup strengthens, and the proportion in the energy expenditure workinprocess cost constantly increases.The energy-saving and cost-reducing enterprise that become realizes transformation, the important channel of enhancing competitiveness.By the end of the year 2002, national Industrial Boiler installed capacity 2002 was 57.6 ten thousand, total thermal power 199.46 ten thousand MW.According to minimum 15% calculating, waste gas residual heat power can reach 200,000 MW.According to our minimum energy utilization ratio 20% of recovery system, the power that can obtain can reach 40,000 MW.
Beijing haze weather is quite dark to people of the whole China's influence.Pollutant emission is greatly the basic reason of air heavily contaminated.Motor vehicle, fire coal, industrial pollution and airborne dust are the main sources of atmosphere pollution.PM2.5 increases by 10 micrograms for every cubic metre according to investigations, and the respiratory disease admission rate can be increased to 3.1%.Purifying exhaust air, very urgent.
The utility model content
The purpose of this utility model is exactly in order to address the above problem, and a kind of boiler waste gas energy recovery is provided and utilizes system, realizes comprising the advantage of environment when it has energy savings.
To achieve these goals, the utility model adopts following technical scheme:
A kind of boiler waste gas energy reclaims and utilizes system, it comprises the flue of collecting waste gas, flue is connected with the heat absorption deduster, the heat absorption deduster is connected with Stirling engine with cooler by heater successively, Stirling engine is connected with generator, and generator connects by the low-temperature plasma exhaust treatment system.
