AN APPARATUS FQR AERATING INTENSIVE DECOMPOSITION REACTORS
The present invention relates to an apparatus for aerating intensive decomposition reactors as set out in the preamble to patent claim 1.
DE-36 31 170 C2 describes a method and an apparatus for the intensive fermentation of bio-waste matter. In this, container-like receptacles are used as decomposition reactors and fresh air passes through these under control, this air being pre-heated as necessary, depending on ambient air temperature. The exhaust air from the decomposition containers is drawn off through a pipe and is deodorized in a bio-filter before being released to the atmosphere. The air supply is monitored by an electronic control system that receives details concerning temperature and/or humidity in the decomposition containers by way of sensors.
DE 40 05 534 Cl and DE 40 05 535 Cl provide additional details concerning the useful structural configuration of the container-like decomposition containers, in particular with reference to the configuration of a perforated base for the air supply, the feed and exhaust air connections, the waste-water connections, and with reference to the closable openings for filling and emptying such containers.
In the intensive decomposition process described in DE 36 31 170 C2, the decomposition process is carried out simultaneously in a plurality of decomposition containers, when the progress of decomposition in the individual containers over time can be extremely varied, for the process takes place in each decomposition container individually. To this end, the containers are set up in a so-called decomposition station that incorporates cans and pipe connections for feed air, exhaust air pipe connections for the exhaust air, a bio-filtration system, ~09~ ~7~
collector systems for collecting and removing waste water, an apparatus for pre-heating the air, and an electronic control system for process control. All of these assemblies are set up separately and, if so required, are accommodated in an appropriate building. To a very large extent, the pipeline and signal line connectors are installed so as to be permanent.
Because the assembly and installation of such a decomposition station must be carried out under construction-site conditions, it entails considerable associated costs. In the case of major ---installations for composting, the costs that are incurred for this are in a reasonable relationship to the total cost for such a system. On the other hand, in the case of smaller installations with a relatively small number of decomposition containers, the construction methods used up to now lead to a disproportionately high fraction of the total costs.
It is the task of the present invention to so develop an apparatus for aerating intensive decomposition containers as described in the premable to patent claim 1 that production of these i5 made cheaper.
This problem has been solved by the distinguishing features of patent claim 1. Advantageous developments of the present invention are described in the sub-claims 2 to 6.
The basic concept of the present invention is that all of the assemblies of the ventilating system, including the control~
systems and line connectors to couple up the individual decomposition reactors, are accommodated in a housing that is produced under workshop conditions and is thus less costly. The standardization that this makes possible leads to series production and to corresponding rationalization and cost advantages. On the one hand, modular construction in the form of containers permits simple formation of high-performance ~ o ~
ventilating systems, for larger composting systems for all that is required i6 to line up an appropriate number of such containers, or place them one on top of the other; increases in capacity can be effected simply. On the other hand, even after it has been installed, such a container remains transportable and can be moved to another site without any major expenses, should this be re~uired.
The system according to the present invention will be described in greater detail below on the basis of embodiments that are shown diagrammatically in the drawing.
The drawing shows one embodiment of the ventilating system according to the present invention, this being based on 20-foot containers. Air that i~ drawn in from the outside is heated as required in an air conditioning apparatus 2 and then blown by a fan through a feedline 4 into the interior of the intensive decomposition reactors (not shown herein). The exhaust air from the reactors is moved by a second fan in the air conditioning apparatus 2 through a waste air pipe that lies, for example, parallel to the feed air pipe, is cooled, and then blown through the bio-filter 3 in order to be deodorized. The condensate that forms during the cooling process in the cooling system 1 is collected in a tank 6. It is preferred that, as far as is possible, the waste heat that is generated during the cooling process not be discharged to the outside but rather used to pre-heat the fresh air, should this be necessary. More expediently, for this reason, the heat exchanger for cooling the exhaust air should also be able to give up the heat for the feed air that is drawn in (air conditioning apparatus 2). The waste water from the decomposition reactors that is generated during the process is pumped through a waste-water pipe, which can in a similar manner be arranged parallel to the feed air pipe 4, into the waste-water tank 5. The condensate and, if so desired, the waste water, can be sprayed into the pre-heated feed air by means of a 20~78 pump system and an atomizing nozzle system in order to achieve operation that is, as far as possible, free of waste water. This is possible because, as a rule, the fresh air that is supplied is not saturated with water. The containers, the supporting base of which is numbered 7, can be insulated either in whole or in part against thermal loss. Such a compact structural unit is able to supply and remove the process air required by a plurality of bio-reactors that are set up on the basis of 20-foot containers.
Because of the restriction to a few transportable units, the present invention provides the possibility that the whole composting system, consisting of the compact unit for ventilating, the intensive decomposition reactors, and the connecting pipelines, can be configured so as to be movable to various locations.
