Example Embodiment

[0032] Example 1

[0033] figure 1 A structural block diagram of a steam air preheating system for the waste incineration industry of the present invention.

[0034] In this embodiment, if figure 1 As shown, the present embodiment provides a steam air preheating system for a waste incineration industry comprising: an ejector line 1, a heat exchanger 2, a hydrophobic group 3, a hydrophobic female tube 4; wherein the steam The pipe 1 is adapted to extract steam in the steam in the steam in the steam in the steam in the steam in the steam in the steam, and the air is absorbed from the heat exchanger 2 to form a hot air discharge; the steam condensed in the heat exchanger 2 is formed. The condensed water flows through the hydrophobic group 3 and is recovered from the hydrophobic mother tube 4 to the corresponding container.

[0035] In the present embodiment, the heat source is a steam of the steam of the air bag 5 and the steam turbine.

[0036] In this embodiment, please refer to...

Abstract

The invention particularly relates to a steam air preheating system and method for the waste incineration industry. The steam air preheating system comprises a steam inlet pipeline, a heat exchanger,a drainage set and a drainage main pipe. The steam inlet pipeline is suitable for extracting steam in a steam pocket and/or a steam turbine and conveying the steam into the heat exchanger, after air absorbs steam heat from the heat exchanger, hot air is formed to be exhausted, and condensate water formed by condensing the steam in the heat exchanger flows through the drainage set and is recycled into a corresponding container through the drainage main pipe. The temperature of the condensate water obtained after steam heat exchange is reduced to 100 DEG C or below through the high-pressure supercooling technology, it is guaranteed that secondary flash evaporation steam is not generated when the pressure is reduced to be equal to the pressure of the corresponding container, corresponding pipelines and valve sets are prevented from being impacted, energy can be saved, and the consumption can be reduced; and the air temperature can ensure that the air is heated to be lower than the steam saturation temperature of 15-20 DEG C, a flash tank and a drainage valve needed by a traditional preheating system are omitted, and the stability is improved while the purchasing cost is reduced.

Description

Technical field [0001] The present invention belongs to the field of waste incineration, and in particular to a steam air preheating system for a waste incineration industry and a preheating method thereof. Background technique [0002] Waste incineration refers to the combustion of human social production and life, and a waste treatment method for reducing, harmless, and resource purposes. Waste incineration treatment technology reduces land resources due to its great reduction of land resources, and reduces pollution to groundwater and air, it can be widely adopted, and domestic waste incineration is the main way to handle domestic garbage, which has garbage decrease Quantitative, the transfer of waste is the characteristics of resources. The domestic waste incineration machinery furnace is used in incineration of domestic garbage, producing high temperature flue gas to power generation through the waste heat boiler and steam turbine generator. [0003] The steam air preheating...
