Abstract

The invention discloses a heat accumulation combustion four-way valve; connecting pipes are symmetrically connected on the outer surface of a container body, and an open pore is formed in the container body by the connecting pipes; the container body is a cylinder and comprises a cylindrical valve disk inner core which is movably nested in the container body, and the valve disk inner core is provided with an inner hole corresponding to the position of the open pore; the valve disk inner core is provided with an inner core cover plate; a clapboard is arranged inside the inner core, and the valve disk inner core is divided into two symmetrical parts that are not communicated with each other; a cover plate is arranged on the container body on the inner core cover plate; a rotating shaft sequentially passes through the cover plate, the inner core cover plate and the valve disk inner core from the center of the cover plate. When in use, the heat accumulation combustion four-way valve leads two hole connecting pipes on a valve body to be respectively connected with a system pipeline; when an internal rotating cylinder rotates at 90 degrees, the direction of the original airflow is changed to complete the direction conversion of air and hot flue gas; the inner core does not need to rotate in a reciprocating way and can continuously rotate, thus being convenient for electric control.

Description

technical field [0001] The invention belongs to the field of heat storage high-temperature air combustion, and relates to equipment in a heat storage combustion system, in particular to a continuously rotating heat storage combustion four-way valve. Background technique [0002] The regenerative combustion technology can heat the combustion-supporting air above the ignition point of the gas, so that the average combustion temperature is increased and the heat utilization efficiency is improved. After the temperature exceeds a certain value, even the combustion process with low oxygen content in the air can burn normally and stably. This is the combination of high-temperature preheated air and oxygen-lean combustion technology, resulting in "High Temperature Air Combustion-HTAC". It not only improves the combustion efficiency, but also reduces the emission concentration of NOx. In this combustion technology, the action frequency of the four-way reversing valve is very high,...
