Problems solved by technology

[0003] In the existing technology, the waste heat of the waste gas in the combustion process of the combustion furnace cannot be fully utilized. The regenerative combustion technology is to make full use of the waste heat of the waste gas discharged during the combustion process. The heat cannot be well utilized, and the structure of the reversing valve in the prior art is unstable, resulting in damage, etc.

Abstract

The invention discloses a dual-drive reversing valve of a heat storage type combustion furnace. The dual-drive reversing valve comprises a reversing valve shell, wherein the internal space of the reversing valve shell is divided into two chambers, i.e., a left gas chamber and a right air chamber; a communicating passage is arranged between the air chamber and the gas chamber; a public chamber is arranged below the communicating passage; the side walls at two ends of the communicating passage are provided with valve plate sealing discs; a valve plate is obstructed in the communicating passage between the gas chamber and the air chamber; and the left outer wall and the right outer wall of the gas chamber and the left outer wall and the right outer wall of the air chamber are fixedly provided with two hydraulic cylinders respectively. The dual-drive reversing valve has the advantages of high working efficiency, stable working state and the like.

Description

technical field [0001] The invention relates to a reversing valve for a regenerative combustion furnace, in particular to a double-drive reversing valve for a regenerative combustion furnace. Background technique [0002] With the increasing shortage of primary energy and the increasing public awareness of environmental protection, maximizing energy utilization and effectively reducing pollutant emissions are important issues we are facing. In the combustion system of heat treatment furnaces, burners are constantly improving. Under the heat load required by the heat treatment furnace, it is necessary to ensure the complete combustion of the fuel, minimize the emission of pollutants, and reduce the generation of nitrogen oxides. [0003] In the existing technology, the waste heat of the waste gas in the combustion process of the combustion furnace cannot be fully utilized. The regenerative combustion technology is to make full use of the waste heat of the waste gas discharged...
