Agricultural waste incineration energy-saving system

Abstract

The invention discloses an agricultural waste incineration energy-saving system. The agricultural waste incineration energy-saving system solves the problem that in the prior art, since heat of smokecannot be effectively utilized, a pipe is corroded. A tube pass inlet of a smoke heat exchanger is connected with a first fan through a pipe. A tube pass outlet of the smoke heat exchanger is connected with a gas inlet of a waste incinerator through a pipe. The incinerator is connected with a waste heat boiler through a pipe. The waste heat boiler, a dust removal device, a third fan, a smoke purifying device and a chimney are sequentially connected through pipes. The pipe connected with the dust removal device and the third fan is provided with a tee joint. A third opening of the tee joint, asecond fan and a shell pass inlet of the smoke heat exchanger are sequentially connected through pipes. A shell pass outlet of the smoke heat exchanger is connected with a hearth of the waste incinerator through a pipe. The chimney is provided with a temperature measuring device. The temperature measuring device comprises a temperature measuring device body and a temperature measuring circuit. Theagricultural waste incineration energy-saving system is simple in structure, scientific and reasonable in design and capable of utilizing the smoke heat to the maximum extent, reduces corrosion to the pipeline, lowers production cost, measures the temperature and saves energy.

Description

technical field [0001] The invention relates to an energy-saving system for burning agricultural waste. Background technique [0002] Agricultural waste incineration Waste heat power plants have high temperature flue gas after waste incineration, and it is directly discharged into the atmosphere, which wastes heat energy and at the same time, contains a large amount of nitrogen oxides, which is easy to pollute the atmosphere. In the prior art, the heat source is utilized by heating the flue gas to the primary air. However, after the flue gas has undergone heat exchange, the temperature will drop, and the acidic substances in it will precipitate and corrode the pipeline, so it is used to purify it and then reheat the air. However, the heat of the purified flue gas will be lost, and the temperature measurement consumes energy. [0003] Therefore, providing an energy-saving system for agricultural waste incineration, which can maximize the use of flue gas heat while reducing ...
