Natural gas boiler tail gas vacuum superconducting recoverer

Abstract

The invention discloses a natural gas boiler tail gas vacuum superconducting recoverer, and relates to the technical field of tail gas recovery. The natural gas boiler tail gas vacuum superconductingrecoverer comprises a heat preservation barrel, a gas inlet mechanism, an adjusting mechanism, a water conveying mechanism, a desulfurization mechanism and a detection control mechanism are arranged on the heat preservation barrel, a spiral vacuum superconducting pipe is installed in the heat preservation barrel in a welded mode, and three sets of separation discs are installed on the inner wall of the heat preservation barrel. According to the natural gas boiler tail gas vacuum superconducting recoverer, the pressure of tail gas exhausted into the spiral vacuum superconducting pipe can be adjusted so that the tail gas can move at a uniform speed, the situation that heat exchange operation is incomplete due to the fact that the tail gas exhaust speed is too high is avoided, and the heat exchange efficiency of the recoverer is ensured; and through the adoption of a vertical structure design, most parts are hidden in the heat preservation barrel, the occupied area of the recoverer is reduced, the space utilization rate is increased, and the recoverer is more intelligent, efficient and practical.

Description

technical field [0001] The invention relates to the technical field of tail gas recovery, in particular to a vacuum superconducting recovery device for natural gas boiler tail gas. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. [0003] The exhaust gas of natural gas boilers contains a lot of heat and harmful substances. At present, most exhaust recoverers on the market are designed from the perspective of heat exchange, ignoring the problem of uneven discharge rate of boiler exhaust gas. The thermal efficiency is reduced, the actual waste heat collection effect becomes poor, and if the speed is too slow, reflux may occur, and this type of recycler is bulky and complicated to operate, and there is no effective treatment method for the exha...

[0003] The exhaust gas of natural gas boilers contains a lot of heat and harmful substances. At present, most exhaust recoverers on the market are designed from the perspective of heat exchange, ignoring the problem of uneven discharge rate of boiler exhaust gas. The thermal efficiency is reduced, the actual waste heat collection effect becomes poor, and if the speed is too slow, reflux may occur, and this type of recycler is bulky and complicated to operate, and there is no effective treatment method for the exhaust gas after heat exchange, which is easy to cause secondary pollution , low practicability, not conducive to promotion and use
