Abstract

Summary of the description of a "transportable biogas reactor in modular form" for a hydropneumatic process in upright form which, for reasons of costs, is industrially manufactured in a complete state on a production line in the works and, for reasons of assembly and transport, is transported in a small form as a whole unit and is installed without great expense for assembly. In the case of operationally larger entire units, the fully complete "module" components are transported and are combined on site using simple means to give an operationally ready unit, the upper parts always being completely the same. All material movements and process circulation movements required within the reactor are caused by its special construction and internal process development and not by vulnerable mechanical devices. By means of these biogas reactors, it is possible that the matter will be profitable even for medium-scale and relatively small agricultural or similarly situated enterprises.

Description

2.1. one mass-produced, industrially finished

portable bio-gas reactor in modular form for a hydro-pneum process, Can be assembled for the respective company size, or for the basic material and the hourly amount with continuous operation, with the same finished Quantity expires as new is added.

All material and process movements within the reactor are due to its special construction, not through vulnerable mechanical devices in the reactor, but the necessary circulations are generated by biomass circulation generated by means of an external circulation pump, as well as by injecting bio-gas to loosen up and entrain the small gas bubbles that have formed for faster rising up.

The transportable bio-gas reactor in modular form is marked by: 2.2. the bottom troughs (oil) for one or more (O2) reactor-1st sump tanks, has a conical (Q1)) or

Pointed (oe) tapered shape so that there is no solid manure material below settle and solidify due to the pressure from above. In the lowest point is the connection (o3) for the biomass circulation, which is carried out by a circulation pump (o4) is caused. The heavy slides through the sloping walls of the floor pan Material in the circulation downwards and is returned by the circulation flow carried along with it, so that no sediment can form. The upheaval only takes place briefly at certain time intervals and takes the material from a downpipe from the upper outlet.

2. The floor pans all have an all-round running around halfway up "Fold" (o6) in which a bio-gas line (o7) with bushing holes is laid. By The fold "prevents material from settling on the line from above and the nozzle holes clogged.

From time to time, this gas line turns the gas supply into bio-gas pressed through (o8) to loosen up the bio-mass in the bio-process to reach and to entrain the formed gas bubbles with upwards.

2.2.3. The main inflow (o9.1) for the to be pumped in is also in the bottom troughs Liquid manure which is warmed up in the feed pipe (o9.2) (10) and in the middle of the reactor is directed. At times, the second feed pipe (11) at the "gas dome" (12) of the reactor, heated fresh manure supplied, with the purpose of the forming t to loosen up and open the skin "or foam blanket for easier exit of the Gas bubbles.

2.3 The upper part 1. of the reactor is the one for the biological process Turnover of the manure. The central axis is double-walled with tubular crossbars (13) Heating pipe (14) installed through the interior of the preheated liquid manure pumped in is pushed up and heated. Above the heating pipe is a pipe (15) from built in from the outside whose closed end reaches into the central unit of the reactor, for inserting a measuring probe (remote thermometer) from the outside for an important control the central temperature. The input (16) and the output (17) of the heating medium is outwards. The upper part has free drainage at a certain height (18) the biologically converted biomass.

2. This vertex (19) of the biomass in the reactor separates the reactor space theoretically in two rooms, the lower one with the bio-mass and the upper # io-gas room. The two "rooms" are related to each other in a certain way. For the free unhindered drainage (20) der11Bio # slurry1? A foam barrier provides for the storage tank (21). The top of the reactor, the gas dome (12), has a manhole and with a cover plate (22) closed on which the connections (11) and the Gas outlet (23) are in the memory. If there are several tops, the lids are closed Cover connecting pipes (24) so that the Bio'Gas rooms have a balancing connection and only needs to be removed from one point. Likewise for "twins" or several container supply line (25) and distribution lines (26) for the supply of fresh organic mass attached.

2.3.3.In the apex height (19) of the bio-mass are opposite Nann holes (27) are available, which are also closed with transparent lids to be able to observe the inside if necessary. In the case of "twins" or more Upper parts are used to connect (28) the apex and outlet lines to one another. A thermal insulation and cover is placed over the domes (29).

2.4 The thermal insulation of the reactor takes place according to the climatic Places of use according to the generally known techniques with mineral wool (31) and a corresponding weatherproof and stable "outer skin" (32) This insulation and outer skin are attached to, at certain intervals, around the reactor # profile steel rings (33) fastened with screws or rivets (34).

The profile steel rings are around no or only small cold bridges to have attached to the reactor wall (36) with spacer tubes (35).
