DESCRIPTION:
BRIEF SUMMARY
This application is a 371 of PCT/DE92/00809, filed Sep. 21, 1992.
The invention relates to a device for the supply, distribution and moistening of gas in a gas-cleaning or decomposition plant, with at least one gas distribution plate provided for receiving the bulk material having gas outlet openings distributed over the plate surface, further with one or more gas distribution chambers provided on the bottom side of the gas distribution plate and in contact with the gas outlet openings, which are connected to one or more gas supply lines, and with spray nozzles to which water can be fed for moistening the gas.
In a device of this kind known from DE 36 34 377 C2, the gas distribution chambers consist of gas channels formed in the gas distribution plates and connecting the gas outlet openings in series, and which are connected over a common collection channel to the supply line for the gas. Between the collection channel and the supply line an inlet chamber is provided, which contains a spraying device for gas moistening with a water tank, spray nozzle arranged thereabove and a pump. The supply line abuts in the inlet chamber and the collection channel is connected with an outlet of the inlet chamber. The gas is moistened in the inlet chamber by the spraying device. The gas so enriched with moisture traverses the collection channel and the gas lines, before it reaches the bulk material layered on the gas distribution plate through the gas outlet openings. As a rule, such installations have relatively large dimensions with regard to the gas distribution plates, so that the channels for gas collection and distribution extend over correspondingly long stretches, between 10 and 100 m in length. While travelling these long stretches the gas loses again a considerable part of the moisture supplied in the inlet chamber, with the result that the gas flowing through the bulk material is already too dry and that the processes supposed to take place in the bulk material can no longer be carried out in optimal conditions because of insufficient humidity.
It is the object of the invention to develop a device of the aforementioned kind, so that the humidity imparted to the gas can act fully on the bulk material.
According to the invention this problem is solved due to the fact that the spray nozzles are arranged under the gas distribution plate, are distributed over the entire plate surface and abut directly in the gas distribution chambers.
The advantage achieved by the invention consists essentially in the fact that the water evenly distributed over the surface of the gas distribution plate is sprayed directly into the gas distribution chambers and therefore the gas moistening takes place immediately under the gas distribution plate in front of the gas passage openings. This way the moistened gas reaches the bulk material over the shortest possible path, namely only by passing through the gas outlet openings and this way can not lose noticeable amounts of moisture, so that the water introduced into the gas can fully reach the bulk material and act upon it. A further very substantial advantage consists in fact that the water introduced through the spray nozzles into the gas distribution chambers, but which is not absorbed in the gas, can exert a permanent cleaning action in the gas distribution chambers and can rinse out the bulk material which reached the gas distribution chambers coming from above through the gas outlet openings.
A preferred embodiment of the invention is characterized in that the gas distribution plate is supported with a clearance on a substrate and that the gas distribution chambers are formed between the substrate and the gas distribution plate, whereby the substrate is waterproof and inclined in the direction of at least one water drainage opening which collects the water running off the substrate. In the gas distribution chambers between the gas distribution plate and the substrate, the gas can distribute itself evenly in any direction and flows towards the gas outlet openings.
