Description

Device for the elimination or neutralization of pollutants and / or offensive odors Substances from gaseous media

The invention relates to a device; for elimination of pollutants and / or odor-causing substances from gaseous media.

In many work processes, pollutants and / or odor-nasty substances arise, with which, for example, the air can be loaded will. Such substances are sometimes aggressive, and sometimes they react with other substances in the air, which then also become environmentally friendly.

The present invention has therefore set itself the task of creating a device with which properly and without Special construction effort Removed or neutralized pollutants and / or odor nuisance substances from gaseous media can be. ! ·

To solve this problem, according to the invention, a device is provided proposed, which is characterized in that

an electrostatic filter and a catalyst are in a housing having at least one inlet and at least one outlet for the gaseous medium is arranged such that the Elektrofilisr vz £ -3er Katslysatns · held in guides and are drawer-like "informed about this and removal, dan, the electric filters directly with the inlet and the catalyst is directly connected to the outlet for the gaseous medium, that a duct containing a fan is arranged between the electrostatic precipitator outlet and the catalyst inlet, and that the electrostatic precipitator is largely parallel to the housing base and the catalytic converter is arranged at an angle to it.

If there is a sufficient amount of a gaseous contaminated medium, it may be necessary to use several devices of the effective type. They are connected to a Raszufuhr- and a gas discharge line it & nn in parallel = circuit. In order to be able to apply the pale gas to each individual device to a large extent, the invention also provides that a flap is arranged in the gas channel between the medium inlet and the electrostatic precipitator.

It is furthermore after correct setting of the medium quantity necessary, the amount as evenly as possible over the subsequent Distribute channel cross-section. It is therefore also proposed that immediately before and immediately in the gas duct to arrange flow baffles behind the electrostatic precipitator.

The use of several devices according to the invention Type in parallel connection, is as compact as possible To strive for construction. In addition, one strives. Devices to be able to assign the proposed type in the modular principle to each other. The invention therefore provides.

that> the upper side of the part of the gas channel before the electrostatic precipitator and the lower side of the part of the oask channel after the catalytic converter are at the same angle to the housing floor t .

I'm going to achieve the goal of a compact design also proposed to arrange the medium inlet and the medium outlet side by side in the housing. As already mentioned above, if several devices of the type according to the invention are used, these mediums are connected in parallel on the downstream side of the medium is the arrangement of the individual devices to each other then such that the bottom of the part of the gas duct after the catalyst on top of the part of the Gas duct in front of the electrostatic precipitator.

The benefits that sit dsr erfis ^ agsgesäeen vicarious be achieved consist ύ & · can be treated properly with your with pollutants and / or odorous substances laden gaseous media. The pollutants and / or odorous substances are almost completely removed from the gaseous medium or! neutralized. In addition, it is advantageous that the construction effort is simple and therefore the device according to the invention can be produced extremely cheaply. The handling, in particular the installation and removal of the electrostatic precipitator and the catalytic converter, do not present any difficulties because of the drawer-like arrangement.

Based on the figures shown in the drawings, the Invention below using an exemplary embodiment wrote. Show it:

Figure 1 is a side view, Figure 2 shows a section of Figure 1 along the line II-II,

For 3 a section of the figure 2 along the line HI-III. Figure k is a plan view of Figure 2,

Fi ^ iir 5 a front view with three units',

FIG. 6 shows the electrostatic precipitator used in an enlarged illustration.

The device according to the invention consists of a housing

1 with at least one inlet 2 and at least one outlet 3 for the gaseous medium. An electrostatic precipitator 4 and a catalyst filter 5 are arranged in the housing 1. The electrostatic precipitator k is directly connected to the medium inlet 1 and the catalyst filter 5 is connected directly to the medium outlet. A duct 7, which contains a fan 6, is provided between the electrostatic precipitator k and the catalyst filter 5. The electrostatic precipitator k and the catalyst filter 5 are held in guides 8 and can be installed and removed via these like a drawer. The electrostatic precipitator 4 is. arranged in the housing 1 largely parallel to the housing bottom 9, while the catalyst filter 5 is arranged at an angle Gk to this. In the gas duct between the medium inlet

2 and electrostatic precipitator 4, a flap 10 is provided. In the gas duct, immediately in front of and immediately behind the electrostatic precipitator k, flow guide plates H are arranged. The upper side 12 of the part of the gas channel in front of the electrostatic precipitator k and the lower side 13 of the part of the gas channel after the catalytic converter filter are inclined with respect to the housing bottom 9 under the same angle β. The medium inlet 2 and the medium outlet 3 lie laterally in the housing 1 and are arranged next to one another. With 17 the control box is referred to.

IS is a mechanical pre-filter in front of the electrostatic precipitator.

The operation of the device according to the invention is as follows:

Φ ··· φ · · ■ ·

Pas gaseous medium is generated when entering the electric filter * »Ionized. This is done so that the air flow several wires 5.1 with 8 kv voltage stretched between earthed metal sheets 5.2.

The ions are lasered onto the dust, haze and Aemsol particles, causing these particles to receive an electrical charge. The charged particles now enter the capacitor-like construction of the Knilektor part, every other plate of which is connected to a positive voltage of k kv, while the others are grounded. The positively charged particles are now thrown out of their path by the plates 5.3, which are under positive voltage, and are deposited on the collector plates 5.4 of the Oegenpolaritat (earthed). The ionizing and collector part is pulled out of the housing like a drawer for cleaning.

The fan 6 sucks in the oas thus cleaned and blist it through the catalyst filter 5.

As a result, the fan 6 with its sau ^ side on the electrostatic precipitator is connected, there is always negative pressure in the area of the parts in front of it on the upstream side. As a result, the electrofiller housing is not tight needs to be and only purified 'gas enters the fan 6.

The catalyst filter 5 is arranged diagonally in its housing, in order to increase the dwell time of the air in the filter through the associated longer path. The catalyst filter absorbs the remaining odorous substances and break them down through oxidation and reduction. That now highly purified gas is passed through outlet 3 into - "· -. Free headed.

The catalyst filter sits in a drawer-like Frame Θ with wedge-shaped cams on the underside.

When pushed into the guides, these socks lift and at the same time seal the Catalyst filter.

In the switch and control box 17 both the necessary fuses and switching elements are housed, such as also a chronological chronicle, which upon reaching a the respective conditions set operating time, first emits a warning signal and after one admitted Safety time the system switches off. This ensures that the catalytic converter filter does not become uncleaned Air becomes unusable at an early stage.
