no. 1 example

[0027] Such as figure 1 As shown, the rotary automatic cleaning switching valve of the regenerative combustion device includes: a valve seat 101 , a cylinder 201 , a rotary valve plate 301 and a rotary device 401 . The valve seat 101 is installed on the air duct opening 103 of the gas distribution box 102, and the side of the valve seat 101 is provided with an annular sealing port 104, and an annular bracket 105 is installed in the annular sealing port 104. Cylinder 201 is installed on the outer wall support 106 of gas distribution box 102, and the push-pull rod 202 of cylinder 201 stretches in the air channel 107 of gas distribution box 102, and this push-pull rod 202 is installed in the linear bearing seat 203 of air channel 107 wall surfaces. A self-aligning bearing seat 303 is installed on the lower wall of the valve plate 302 of the rotating valve plate 301 , and the connecting shaft head 204 of the push-pull rod 202 is installed in the self-aligning bearing seat 303 . A...

Abstract

The invention discloses a rotary automatic cleaning type switching valve of a thermal storage combustion device. The rotary automatic cleaning type switching valve of the thermal storage combustion device comprises a valve seat, a rotary valve plate, a cylinder and a rotary device; the valve seat and the rotary valve plate are installed relatively eccentrically; the rotary device drives the rotary valve plate to rotate; the valve plate eccentrically rotates relative to an annular sealing opening; the annular wall face of the annular sealing opening makes contact with and rubs with the sealing wall face of the valve plate for automatically cleaning away dirt; the rotary automatic cleaning type switching valve conducts automatic cleaning work under the working condition of non-stop; and at the same time, the defect that the fatigue deformation of a valve plate affects the sealing effect is overcome, and the waste gas purifying quality and efficiency of the thermal storage combustion device are substantially improved.

Description

technical field [0001] The invention relates to a rotary automatic cleaning switching valve of a regenerative combustion device, in particular to the technical field of a regenerative (RTO) combustion device for waste gas treatment. Background technique [0002] The current regenerative combustion device (RTO) heats the organic waste gas discharged from the production through the heat storage ceramics, and the temperature rises rapidly. Under the action of gas combustion and heating in the furnace, the temperature reaches 680-1050°C, and the VOCs in the organic waste gas At this high temperature, it is directly decomposed into carbon dioxide and water vapor to form odorless high-temperature flue gas, which then flows through the low-temperature regenerative ceramics. The organic waste gas is decomposed, and the temperature of the high-temperature flue gas itself is greatly reduced. After heat exchange with other media through the heat recovery system, the temperature of the ...
