Embodiment 1

[0071] Such as Figure 1~2 An embodiment of a regenerative oxidation furnace shown includes a furnace body 1, a waste gas inlet pipe 2 and an exhaust gas discharge pipe 3, the upper part of the furnace body 1 is provided with a combustion chamber 4, and the lower part of the furnace body 1 A plurality of regenerators 5 communicating with the combustion chamber 4 are provided; the bottom of the regenerator 5 is provided with an asphalt flue gas inlet, a purge port, and an exhaust outlet. The asphalt flue gas inlet is connected through the corresponding intake branch pipe 6, and one end of the tail gas discharge pipe 3 is connected with the tail gas discharge port through the corresponding exhaust branch pipe 7. The tail gas discharge pipe 3 The other end of the chimney is provided with a chimney 8; the second temperature controller 9 and the purge pipe 10 are sequentially arranged on the tail gas discharge pipe 3 according to the tail gas flow; the other end of the purge pipe 1...

Embodiment 2

[0083] A process for cleaning and preventing clogging in a regenerative oxidation furnace. The regenerative oxidation furnace in this embodiment includes three regenerators, and the regenerative oxidation furnace adopts cleaning mode one to clean and prevent clogging ;

[0084] The decontamination and anti-blocking method of the decontamination mode one specifically includes the following steps:

[0085] Step 1. First, adjust the working state of the regenerative oxidation furnace to be the operation state of the cleaning mode one. The operation state of the cleaning mode one is as follows: increase the air volume of the purge fan to be greater than or equal to the purge in the waste gas treatment mode 2 times the air volume of the fan (because the operating frequency of the blowing fan in the exhaust gas treatment mode is about 25-28Hz in this embodiment, the air volume is 3000-3500m 3 / h, so in the cleaning mode, the operating frequency of the blowing fan is greater than 45...

Embodiment 3

[0091] A process for cleaning and preventing clogging in a regenerative oxidation furnace. The regenerative oxidation furnace in this embodiment includes three regenerators, and the regenerative oxidation furnace adopts cleaning mode 2 to clean and prevent clogging ;

[0092] The decontamination and anti-blocking method of the decontamination mode two specifically includes the following steps:

[0093] Step 1. Adjust the working state of the regenerative oxidation furnace to the operating state of the cleaning mode 2. The operating state of the cleaning mode 2 is as follows: increase the air volume of the blowing fan to be greater than or equal to the air volume of the blowing fan in the waste gas treatment mode 2 times (due to the operating frequency of the blowing blower in the exhaust gas treatment mode is about 25-28Hz in this embodiment, and the air volume is 3000-3500m 3 / h, so in the cleaning mode, the operating frequency of the blowing fan is greater than 45Hz, and th...

Abstract

The invention relates to a regenerative oxidation furnace and its decontamination and anti-blocking process. The regenerative oxidation furnace includes a furnace body, a waste gas inlet pipe, a tail gas discharge pipe, a combustion chamber, and a plurality of regenerators; the tail gas discharge A purge pipe is arranged on the pipe; the other end of the purge pipe communicates with the purge port through a purge branch pipe; a mixer and a purge fan are arranged on the purge pipe, and A furnace bleed air pipe is installed; and two cleaning modes are determined. Cleaning mode 1 uses 200°C and 250°C sub-high temperature gas to purge each regenerator for multiple rounds; Cleaning mode 2 uses 180°C and 230°C Two kinds of sub-high temperature gas purging, each round is carried out in the mode of 15 minutes of sub-high temperature and 5 minutes of low temperature; the two cleaning modes are alternately operated and complement each other, which not only ensures good smoke emission indicators, but also achieves cleaning and anti-blocking, The purpose of ensuring the long-term stable operation of the RTO furnace.

Description

technical field [0001] The invention belongs to the field of environmental protection treatment of asphalt flue gas, and in particular relates to a regenerative oxidation furnace and a decontamination and anti-blocking process. Background technique [0002] RTO (Regenerative Thermal Oxidizer, RTO for short) furnace, regenerative oxidation furnace. The principle is to oxidize the combustible waste gas into corresponding oxides and water at high temperature, thereby purifying the waste gas; the high-temperature flue gas generated after oxidation passes through the special honeycomb ceramic regenerator, which makes the ceramic heat up and store heat, so that the furnace cavity is always Maintain a very high working temperature, save fuel consumption for exhaust gas preheating and heating, and reduce operating costs. The main structure of the RTO furnace is composed of a combustion chamber, a ceramic regenerator bed and a switching valve; the ceramic regenerator bed is composed...
