Embodiment 1

[0024] Such as figure 1 A device for switching between organic waste gas and flue gas channels is shown, including a body 100, which includes an upper gas channel 1, a lower gas channel 2, and a vertical channel 3, wherein one side of the upper gas channel is connected to the intake chamber 200, and the lower gas channel The other side is connected to the air outlet chamber 300 . The vertical passage is divided into the first vertical passage 5 and the second vertical passage 6 by the partition plate 4, the first vertical passage includes the first upper passage opening 7 arranged on the top, the first lower passage opening 8 arranged at the bottom, and the second vertical passage The channel includes a second upper channel port 9 arranged at the top, a second lower channel port 10 arranged at the bottom, a first hydraulic valve 11 is arranged between the upper gas channel and the first vertical channel, and the upper gas channel and the second vertical channel There is a sec...

Embodiment 2

[0031] A channel switching method of an organic waste gas-flue gas channel switching device. In Example 1, an organic waste gas-flue gas channel switching device, in the working state, the upper channel opening of the first vertical channel is closed and the lower channel opening is opened, The upper channel of the second vertical channel is opened and the lower channel is closed, so that the exhaust gas enters the second vent from the air inlet chamber, and then flows out from the first vent to the outlet chamber through the main body of the RTO equipment; when the valve is switched, the first vertical channel The upper channel is opened and the lower channel is closed, the upper channel of the second vertical channel is closed and the lower channel is opened, so that the exhaust gas enters the first vent from the air inlet chamber, and then flows out from the second vent to the outlet chamber through the main body of the RTO equipment ; Such reciprocating opening and closing ...

Abstract

The invention discloses organic waste gas-smoke channel switching equipment and a channel switching method. The equipment and the method are applied to a double-chamber RTO waste gas treatment system in the field of organic waste gas treatment. The switching equipment is connected with an air inlet chamber, an air outlet chamber and an RTO equipment body, and comprises an upper gas channel, a lower gas channel and a vertical channel, the vertical channel is divided by a separating plate into two parts, the two vertical channel parts comprise an upper channel opening and a lower channel opening, hydraulic valves are arranged between the upper gas channel and the two vertical channel parts, the bottoms of valve rods are connected with a baffle, and the baffle is located between the upper channel opening and the lower channel opening; and a vent opening is formed in one side of the vertical channel. According to the switching method, motion position changes of the two valve rods are switched to achieve switching of smoke and waste gas flowing directions of the RTO equipment. The system switching speed is high, the thrust force of the hydraulic valves is large, the overall structure is compact, the floor space of the RTO equipment is greatly reduced, installation is convenient, the closed achieving manner of the baffle and the channel is metal sealing, the sealing effect is good, and the service life is as long as million times.

Description

technical field [0001] The invention relates to a ventilation duct part of a two-chamber regenerative thermal oxidation furnace (RTO), in particular to a device and a channel switching method for organic waste gas-flue gas channel switching. Background technique [0002] The working principle of the two-chamber regenerative thermal oxidation furnace (RTO) equipment is to use the principle that organic waste gas is oxidized at high temperature in the equipment to release carbon dioxide and water vapor, so as to achieve the purpose of removing organic matter, and the efficient two-chamber RTO equipment can remove VOC The rate can be as high as 98%. The main structure of the two-chamber RTO is composed of a combustion chamber, two ceramic packing regenerator beds and two switching valves. When the organic waste gas passes through one side of the regenerator, it will be heated to a certain temperature, enter the combustion chamber for combustion, and flow through the other side....
