DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exhaust gas purifying apparatus for removing fine particles contained in exhaust gas from automobiles and incinerators.

[0002]

2. Description of the Related Art Exhaust from automobiles and incinerators contains dust, which pollutes human lungs and the environment.
It has become a social problem. In order to remove such dust, the conventional exhaust gas purifying apparatus is provided with a filter in an exhaust path, and performs filtration or generates static electricity to be adsorbed.

[0003]

However, in the conventional exhaust gas purifying apparatus using the filter, there is a problem that the filter is clogged with the dust and hinders the exhaust, thereby possibly causing a failure or accident of the combustion engine. Was. Also,
The conventional exhaust gas purifier using static electricity has a problem that running costs are increased due to generation of static electricity.

The present invention has been made in view of such a conventional problem, and it is difficult for a combustion engine to be broken down or an accident due to clogging, and exhaust gas can be purified without increasing running costs. It is intended to provide a purification device.

[0005]

According to a first aspect of the present invention, there is provided an exhaust gas purifying apparatus, comprising: a main body container having an exhaust inlet and an exhaust outlet; A plurality of adsorbents that adsorb and can be disturbed by an exhaust pressure, and are accommodated in the main body container so as to separate the exhaust inlet and the exhaust outlet, and the adsorbents are disposed on an exhaust inlet side and an exhaust outlet side. Has a plurality of vent holes of a size that cannot pass therethrough, and an adsorbent container for accommodating the adsorbent with a gap in which the adsorbent can disturb, and the adsorbent container is provided in the main container. It is characterized in that a plurality thereof are arranged in parallel at intervals and are detachably provided in the main body container.

[0006] The plurality of adsorbents that can be disturbed are, for example, sand,
It consists of charcoal powder, activated carbon powder, zeolite powder, flaky paper and others. Even if the adsorbent fluctuates throughout the adsorbent container,
It may be disturbed only in a part of the adsorbent container. The vent of the adsorbent container is preferably made of a mesh so as not to obstruct the flow of the exhaust gas. The main body container and the adsorbent container may be made of plastic, stainless steel, or any other material.

According to a second aspect of the present invention, there is provided the exhaust gas purifying apparatus, wherein the adsorbent is made of sand.

[0011]

In the exhaust gas purifying apparatus according to the first aspect of the present invention, for example, an exhaust gas inlet is connected to an exhaust gas of an automobile or the like. The exhaust gas that has entered the main body container from the exhaust gas inlet enters the adsorbent container through the vent hole on the exhaust gas inlet side. In the adsorbent container, the adsorbent fluctuates due to the pressure of the exhaust gas passing therethrough. The disturbed adsorbent adsorbs fine particles in the exhaust gas. Since there is a gap between the adsorbents that are disturbed by the gap in the adsorbent container, the passage of exhaust gas is not completely prevented. Exhaust gas purified through the adsorbent container is discharged from an exhaust outlet of the main body container through a passage hole on the exhaust outlet side. As the exhaust gas passes through the plurality of adsorbent containers, purification gradually proceeds, and the degree of purification of the exhaust gas can be increased. The adsorbent container is detached from the main container, so that the adsorbent can be easily washed.

[0013] In the exhaust gas purifying apparatus according to the third aspect of the present invention, the receiving tray receives exhaust gas from the exhaust gas inlet. For this reason, the pressure of the exhaust gas is reduced, and the main body container and the adsorbent container do not directly receive the heat of the exhaust gas.

In the exhaust gas purifying apparatus according to the fourth aspect of the present invention, the adsorbent container rotates by receiving the exhaust gas from the exhaust gas inlet through the blade. When the adsorbent container rotates, the internal adsorbent is agitated, the contact with the exhaust gas increases, and the fine particles in the exhaust gas are easily adsorbed.
