Problems solved by technology

If it is summer, there is still an advantage of dehumidification, but the temperature of the supply air is raised due to the heat of adsorption of dehumidification, so there is also a problem that it cannot be recooled without recooling by an evaporative cooler or an aftercooler installed at the outlet of the rotor treatment. Disadvantages of indoor air supply
[0026] And, with Image 6 In this way, the adsorption performance of carbon dioxide tends to be inhibited due to the temperature rise caused by the heat of adsorption of dehumidification, and there is also a performance problem that the separation performance of carbon dioxide deteriorates due to the consumption of regeneration energy in the desorption heat of water vapor in the desorption regeneration region. shortcoming
[0027] In addition, it becomes a condition for humidification in winter, and the dehumidification function becomes a disadvantage, and there is no residual heat, so it cannot be used in winter
Namely, there is a fundamental disadvantage that it can only be applied during the summer period

Embodiment 1

[0062] Below, according to image 3 Embodiments of the ventilating and air-conditioning apparatus of the present invention will be described in detail. 1 is a honeycomb rotor, which corrugates a porous sheet of inorganic fibers such as glass fibers to form a rotor-like honeycomb rotor, and carries the activity of an amine carbon dioxide absorbent added to absorb carbon dioxide. Carbon adsorption material.

[0063] The rotor is accommodated in a sealed casing divided into a treatment area and a desorption regeneration area, and the rotor is configured to be rotationally driven by a gear motor.

[0064]Introduce the treated air into the treatment area, absorb and remove pollutants such as carbon dioxide contained in the treated air, and supply purified air to the room. The process air may be return air or external air, and may be mixed according to the purpose. The rotor honeycomb that absorbs carbon dioxide or pollutants rotates and moves to the desorption regeneration area,...

Embodiment 2

[0067] The flow chart of embodiment 2 of the present invention is shown in Figure 4 . The structure of the device is the same as that of Example 1 image 3 almost the same. For the honeycomb rotor 1, 30 g / m2 porous paper containing plastic fibers mainly composed of inorganic fibers such as glass fibers is coated with fine particles of an amine ion exchange resin with a particle size distribution of 0.02 to 0.1 mm and an average particle size of 0.03 mm. Slurry liquid mixed with activated carbon particles and heat-resistant and water-resistant binder, the dried sheet ( Figure 13 ) was corrugated at a pitch of 3.0 mm and a height of 2.0 mm, and was wound into a rotor to obtain a honeycomb rotor 1 with a bulk density of 150 kg / m3 containing 50% by weight of amine ion exchange resin and fine particles of activated carbon .

[0068] In the present invention, since steam is used for the desorption of adsorbed carbon dioxide, it is not necessary to make the honeycomb rotor 1 in...

Embodiment 3

[0071] With regard to the honeycomb rotor, a porous paper of 35 g / m2 mainly composed of inorganic fibers such as glass fibers is corrugated at a pitch of 3.0 mm and a height of 2.0 mm, and it is wound and rotorized to obtain a honeycomb rotor that contains 70% by weight. A honeycomb rotor 1 with a volume density of 150 kg / m3 of carbon dioxide occlusion gel obtained by dip-coating and drying an amine-based polymer gel having carbon dioxide occlusion properties.

[0072] In terms of the structure of the device, it is roughly the same as Embodiment 2, but as Figure 5 In this way, the honeycomb rotor is fixed in the rotor adsorption device with the outer peripheral sealing structure, the process air is passed to the air conditioner, and the air that has passed through the device is returned to the room again. The device is characterized in that the adsorption device Sector-shaped funnels with seals rotating co-rotating around the rotor shaft are attached to the front and back of ...

Abstract

The present invention provides a ventilation and air-conditioning device with no energy loss associated with ventilation, high energy efficiency, space saving and low cost. In order to solve the above problems, the present invention is characterized by having a honeycomb rotor having a function of adsorbing or absorbing pollutants such as carbon dioxide, and disposing the honeycomb rotor in a rotor rotating device having at least a treatment area and a desorption / regeneration area, so that the treated air is The gas is supplied to the processing area to remove pollutants such as carbon dioxide, and saturated steam is introduced into the regeneration and desorption area to desorb pollutants such as carbon dioxide and discharge it to the outside.

Description

technical field [0001] The present invention provides a ventilating and air-conditioning device for removing pollutants such as carbon dioxide. The ventilating and air-conditioning device for removing pollutants such as carbon dioxide uses air-conditioning devices capable of adsorbing and removing pollutants such as carbon dioxide, VOC, and odor generated indoors or intruded from outside air. Rotors for pollutants such as SOx, NOx, and VOC remove these pollutants, thereby improving indoor air quality through a small amount of ventilation. Background technique [0002] Used in office buildings or commercial buildings and residential spaces such as figure 1 Such ventilating and air-conditioning devices are mainly used for the purpose of exhausting pollutants such as carbon dioxide contained in human breath and VOC generated from building materials, OA equipment, and the like. If ventilation is performed during the cooling and heating period, the cooling and heating load will ...
