Fig. 4 is a schematic top view of a rotary wheel apparatus for treating organic waste gas with granular activated carbon according to a preferred embodiment of the present invention.
In a further preferred embodiment as shown in fig. 4, the cartridge rotor structural body further includes a first region 61 disposed on the inner wall side of the cartridge rotor structural body and a second region 62 disposed on the outer wall side of the cartridge rotor structural body, the region between the first region 61 and the second region 62 being a desorption region; the drum type rotating wheel structure main body further comprises a third zone 63 arranged on the inner wall side of the drum type rotating wheel structure main body and a fourth zone 64 arranged on the outer wall side of the drum type rotating wheel structure main body, the zone between the third zone 63 and the fourth zone 64 is a purging zone, and the zone of the drum type rotating wheel structure main body except for the desorption zone and the purging zone is a purging cooling zone; wherein in the rotating direction of the cylinder type rotating wheel structure main body, the purging area is positioned at the downstream of the desorption area; wherein the first region 61 blows hot air to the second region 62 upon rotation of the drum structure body, and the fourth region 64 blows cooling air to the third region 63 upon rotation of the drum structure body.
Specifically, the rotating wheel has 10-25 regions which are different according to the diameter of the rotating wheel and are respectively separated by a firewall, the adsorption region is a plurality of regions, the desorption region is a region, the purging region is a region, and the purging region is close to the desorption region; the runner rotates slowly during the desorption, and each zone passes through the desorption zone and the blowing cooling zone in sequence to complete the processes of adsorption, desorption, blowing cooling and re-adsorption.
For example, the rotation speed of the wheel is set according to the concentration obtained during the initial commissioning, and the concentration suitable for combustion is very important. When the runner passes through the area between the first area 61 and the second area 62 every millimeter, the first area 61 blows hot air to the second area 62, and the second area 62 receives the high-concentration small-air-volume organic waste gas (the process name is desorption concentration). The activated carbon is also regenerated, and the desorption temperature is determined according to the boiling point of the waste gas factor. Then sending the high-concentration small-air-volume waste gas to a combustion furnace for incineration. The heat energy of the waste gas after combustion is transferred to the heat energy which is desorbed and concentrated from the first zone 61 to the second zone 62 through the heat exchange system. The desorption air adopts air with residual temperature after suction and sweeping.
Although the carbon passing through the desorption zone is regenerated (the carbon recovers the original characteristics after the adsorption substances are removed, namely regeneration), the carbon has high temperature and cannot adsorb organic substances again. At this time, purging cooling is required, the cooling is carried out to the normal temperature, the original carbon characteristic is completely recovered, and the purging air is taken from the air in the runner in the purging area, namely the fourth area 64 purges the cooling air to the third area 63 when the drum runner structure body rotates.
Carbon itself is a very effective material for adsorbing organic matters, and is also a material with a very strong heat absorption function.
When the first zone 61 blows hot air with a set temperature, the second zone 62 receives the hot air with a slightly lower temperature than the set temperature, if the hot air with the same value as the set temperature is received, the heating process of the whole desorption system is closed, and the process is recovered after the temperature is normal. If the second zone 62 receives a value higher than the set temperature, the runner can be started to only one zone, namely three zones of spraying systems, on the left and right of the desorption zone, and the firewall plays a role in isolating the temperature.
If the temperature rises continuously, the whole equipment is powered off (except for a fire-fighting system), and meanwhile, the whole rotating wheel (equipment) starts the spraying fire-fighting system.
A concentrated burning type environmental protection equipment consumes energy, and is mainly shown in that: one large fan for obtaining negative pressure energy occupies about 1/3 of total energy consumption of the whole equipment, and the rest of energy consumption, namely incineration energy, occupies about 2/3 of the total energy consumption of the equipment. The main adsorption material of the product represented by a foreign zeolite molecular sieve rotating wheel is zeolite powder which is used as an adsorption matrix and is combined with the glass corrugated fiber paper shape, the adhesion amount of the zeolite powder is very small, and therefore, the zeolite powder needs to be adsorbed and desorbed while being combusted. (also called real-time desorption) and high energy consumption for combustion. The energy consumption is higher when the intake gas concentration is unstable due to non-full production. It can be seen that this is real-time rotation, real-time desorption and real-time combustion.
The adsorption efficiency and the universality of the active carbon are much higher than those of zeolite molecular sieves, and the filling amount of an active carbon adsorption matrix of the rotating wheel made of the active carbon is dozens of times of that of zeolite powder of the zeolite rotating wheel, so that the active carbon rotating wheel has a very good temporary storage function of organic matters.
The center of the active carbon rotating wheel is provided with a concentration detection value which is set according to the local environmental protection emission standard. When the concentration of VOCs in the exhaust gas in the center reaches or approaches a set value, the rotating wheel starts to select desorption regeneration, incineration and reabsorption.
