Embodiment 1
[0031] Such as figure 1 As shown, the embodiment of the present invention provides a system for efficiently purifying VOCs produced in the roast duck production process, including: a negative pressure gas storage device 1 and a VOCs thermal combustion device 2, and the air inlet of the negative pressure gas storage device 1 The first pipeline 3 is connected to the furnace cavity of the airtight roast duck oven 4, and the first valve 5 is arranged on the first pipeline 3; The combustion-supporting gas inlet of the combustion device 2 is connected, and the second pipe 6 is provided with a flue gas conveying device 7 and a second valve 8 .
[0032] In the above system, the negative pressure gas storage device can be a vacuum tank, the flue gas delivery device can be a vacuum pump, and the VOCs thermal combustion device refers to a device that uses a thermal combustion method to process VOCs. The thermal combustion method is generally used to deal with the low concentration of VO...
Embodiment 2
[0058] Such as image 3 As shown, the embodiment of the present invention provides a method for efficiently purifying VOCs produced in the roast duck production process using the system as described in Embodiment 1, including:
[0059] S1, open the first valve, so that the VOCs accumulated in the airtight roast duck oven quickly enter the negative pressure gas storage device under the action of negative pressure;
[0060] S2, closing the first valve, opening the second valve, starting the flue gas delivery device to deliver the gas in the negative pressure gas storage device to the combustion-supporting gas inlet of the VOCs thermal combustion device;
[0061] S3, start the VOCs thermal combustion device to burn and purify the VOCs.
[0062] Further, the opening of the first valve includes:
[0063] The main controller detects whether the timing of the timer is over, and if so, generates a first control command and sends it to the first valve, and the first control command i...
