Avasite flue gas waste heat treatment device based on heat exchange principle

Abstract

The invention relates to an avasite flue gas waste heat treatment device, in particular to an avasite flue gas waste heat treatment device based on a heat exchange principle. The avasite flue gas waste heat treatment device comprises a support frame, an air inlet pipe, a heat conduction partition plate, a waste heat absorption component and the like; and the air inlet pipe is fixedly installed on the support frame, the heat conduction partition plate is arranged on the support frame, and the waste heat absorption component is arranged on the support frame. Under the action of a cam and a first spring, a vibration frame vibrates up and down in a reciprocating mode to stir water in the support frame, so that the flowing speed of the water in the support frame is increased, the water can make uniform contact with a heat conduction air pipe, the water can fully absorb heat on the heat conduction air pipe, the water can be rapidly heated, and the heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to a waste heat treatment device for silicon-iron ore flue gas, in particular to a waste heat treatment device for silicon-iron ore flue gas based on the heat exchange principle. Background technique [0002] With the rapid development of my country's economy, the construction of various projects has achieved corresponding achievements. The country pays more attention to the emission of greenhouse gases. Therefore, energy conservation and emission reduction have become a national key inspection project. The heat content of the flue gas discharged from the submerged arc furnace is large, so the waste heat is recovered The potential benefit is very high. Generally, the flue gas exhaust pipe is passed into the cold water pipe to heat the cold water in the water pipe. The heated water can meet the daily production needs. [0003] In the prior art, the flue gas discharged from the flue gas exhaust pipe in the existing submerged arc furn...

Problems solved by technology

[0003] In the prior art, the flue gas discharged from the flue gas exhaust pipe in the existing submerged arc furnace waste heat exchange device contains a large amount of particulate matter. In order to prevent the particulate matter from depositing in the pipe, a filter screen is installed at the flue gas outlet to filter the particulate matter. However, the filter needs to be replaced after a certain period of time, and the operation of replacing the filter is relatively complicated, and the existing submerged arc furnace waste heat exchange device only uses gas, and has no function of using the waste heat of solid particles in the flue gas
