Technical Field
The utility model belongs to the technical field of organic waste gas treatment technique and specifically relates to a do benefit to stable discharge to reach standard, retrieve simultaneously partly thermal energy behind the organic waste gas burning and get hot mechanism based on zeolite runner's RTO burner's furnace.
Background
With the increasing environment protection situation, the applications of waste gas treatment equipment (such as RTO, activated carbon adsorption/desorption + catalytic combustion, photo-oxygen plasma, CO, RCO, etc.) are becoming more and more extensive. The structural flow of the hearth heat-taking mechanism of the RTO combustion device based on the zeolite rotating wheel is shown in figure 1, when the hearth heat-taking is carried out, an RTO exhaust fan 5 is used as a power fan, the heat is exchanged through a heat exchanger 2 and then directly discharged to a chimney 6 to be mixed with waste gas passing through the zeolite rotating wheel 7 for discharge, and the waste gas passing through the zeolite rotating wheel 7 is discharged to the chimney 6 by using a main exhaust fan 8 as the power fan. When the initial concentration of the waste gas is higher, the concentration ratio of the zeolite rotating wheel 7 is smaller, and the desorption air volume is larger, so that the air volume of the waste gas heated by the hearth is larger, a large amount of incompletely combusted organic waste gas (VOCs) is contained, and the emission standard is difficult to meet under the increasingly severe environmental protection requirement. Meanwhile, the temperature of the directly discharged waste gas is about 230 ℃, so that heat loss is caused, and the running cost of the natural gas is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the problem that prior art exists, provide one kind and do benefit to stable discharge to reach standard, retrieve the RTO burner's based on zeolite runner mechanism of getting heat after the organic waste gas burning device simultaneously.
The utility model aims at solving through the following technical scheme:
the utility model provides a heat mechanism is got to RTO burner's furnace based on zeolite runner, includes RTO combustion chamber and heat exchanger, its characterized in that: the two ends of the heat exchanger are respectively communicated with the two sides of the hearth of the RTO combustion chamber through corresponding high-temperature waste gas pipes, and one high-temperature waste gas pipe is provided with a thermal circulation fan, so that high-temperature waste gas directly coming out from the RTO combustion chamber forms an internal circulation.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 2: a hearth heat taking mechanism of an RTO combustion device based on a zeolite rotating wheel comprises an RTO combustion chamber 1 and a heat exchanger 2, wherein two ends of the heat exchanger 2 are respectively communicated with two sides of a hearth of the RTO combustion chamber 1 through corresponding high-temperature exhaust gas pipes 3, and one high-temperature exhaust gas pipe 3 is provided with a thermal circulating fan 4 which can resist the temperature of not lower than 300 ℃, so that the high-temperature exhaust gas directly coming out of the RTO combustion chamber 1 forms an internal circulation; the thermal circulation fan 4 is positioned on the high-temperature waste gas pipe 3 at the heat exchange waste gas outlet side of the heat exchanger 2, and the temperature of the waste gas output from the heat exchange waste gas outlet of the heat exchanger 2 is not lower than 200 ℃.
As shown in fig. 2: when the hearth heat taking mechanism of the utility model is used, high temperature waste gas is discharged from the right side of the RTO combustion chamber 1, is subjected to heat exchange by the heat exchanger 2, and is sent into the RTO combustion chamber 1 from the left side of the RTO combustion chamber 1 by the heat circulating fan 4, and the circulation is carried out; the waste gas passing through the zeolite rotating wheel 7 is discharged into the chimney 6 by adopting the main exhaust fan 8 as a power fan, and the emission standard can be met. Because the waste gas that the furnace got heat no longer directly discharges, the waste gas of zeolite runner 7 can stably discharge, and the waste gas temperature that the heat transfer got down still sends into RTO combustion chamber 1 simultaneously, directly discharges relatively, and the heat is lossless, reduces the use amount of natural gas for the burning.
The utility model discloses a furnace gets hot mechanism through increasing a thermal cycle fan 4 that temperature resistant 300 ℃ or more, high temperature waste gas from one side of RTO combustion chamber 1, send into RTO combustion chamber 1 from the opposite side of RTO combustion chamber 1 again through thermal cycle fan 4 after heat exchanger 2 heat transfer, so circulate; because the hot waste gas of furnace get is no longer directly discharged, through thermal cycle fan 4 at RTO combustion chamber 1 inner loop for the heat that contains in the waste gas of temperature about 230 ℃ can be retrieved after the heat transfer, has reduced the use amount of combustor natural gas, and has guaranteed the stable discharge to reach standard of equipment.
