The invention relates to the field of sewerage and mostly intended for use in agriculture to livestock and poultry farms, complexes and factories, which from manure, manure and organic waste of plant produce combustible biogas and high quality disinfected by pathogenic microorganisms, helminths, their eggs and weed seeds organic fertilizers. Wet gasholder variable capacitor comprises elevating a liquid bell and reservoir bottom and pipes for filling and emptying the tank flowing liquid used as a gate hoisting lowered bell and the pipe (pipes) the supply and removal of biogas produced in the digester during the anaerobic fermentation of organic waste . The bottom of the tank is conical. At the bottom of the bottom of the fence installed pipe emptying the tank from settling sediment flowing liquid. The use of the invention will reduce operating costs.

DESCRIPTION OF THE INVENTION

The invention relates to the field of sewerage and mostly intended for use in agriculture to livestock and poultry farms, factories and farms, on which manure, dung and crop waste is produced in the digesters combustible biogas and high quality disinfected by pathogenic microorganisms, helminths, their eggs and seeds weeds organic fertilizers.

Known typical wet gas tank of variable capacity with water-filled tank, performing the role of water seal lifting and lowering gas-filled bell, then how to prevent freezing of water in the tank gas tank in winter and maintain the water temperature in the cold at least + 5 ° C, it is heated using steam-jet at a rate of elevators at this hour at 70-120 kcal of heat per cubic meter of water. / See. Typical projects wet gas tanks of different capacities №707-2-18-24c-86, developed GIAP approved and enacted Fertilizers Protocol №25-III on September 10, 1985 /.

The disadvantage of a typical wet gas tank is a variable capacitor that for heating water in the tank in winter need to spend a significant amount of thermal energy.

Known and another wet gasholder variable capacitor comprising elevating a liquid bell and a tank with a flat bottom and pipes for filling and emptying of the running water, is used as the gate hoisting lowered bell nozzle or multiple nozzles for supplying and removing biogas produced in the digester anaerobic fermentation of organic waste, which is given in British patent №2190682 tml. C 02 F 11/04.

The disadvantage of this known from UK patent application №2190682 wet gasholder variable capacitor is that you must spend running water for heating which is to prevent its freezing consumed warm in winter.

However, in its technical essence and the achieved result at the request of the UK known wet gasholder variable capacitance is the closest to the invention.

The object of the present invention is to provide a wet gas tank of variable capacity, which eliminated to him the above shortcomings, would provide cost savings on its operation due to the use as a flow-replaceable liquid discharged from the digester heated anaerobically fermented to 35 ° C / mesophilic mode / or 60 ° C / thermophilic conditions / wet weight of 94-97% and having deposited therein and the precipitated organic substances.

According to the invention the task set in the performance of the wet gas tank of variable capacity is achieved by the fact that the tank bottom is tapered at the base of which is installed fence of the pipe emptying the tank from settling sediment flowing liquid, and as the flow of liquid applied heated discharged from the digester anaerobically fermented the plated liquid mass, while the periodicity of input into the tank wet gasholder applied fermented in heated digester weight adjusted in accordance with the frequency of unloading fermented pulp from the digester tank and drain pipe made from the liquid and cleaning hatch on the tank bottom sediments.

The drawings schematically shows the device wet gas tank of variable capacity.

Proposed wet gasholder /fig.1 variable capacity and 2/1 comprises a tank with conical bottom 2 and a lifting and lowering the bell 3. The tank 1 made filling nozzles 4 and 5 emptying the tank 1 flowing liquid pipe / fittings / supply and removal of biogas 6, the suction portion 7 pipe emptying 5 of the tank 1 from flowing liquid with sediment, designed as a bent pipe, the lower end of which is mounted in the center of the conical bottom 2 and the upper - is mounted in an enlarged upper portion of the curved discharge pipe 5 at a distance "B" from 1 and the top of the tank slightly above the nozzle 5, which provides a drain from the tank 1 flowing liquid with sediment flowing from the upper end of the tube 7. chamfer emptying liquid from the bottom nozzle 2 is 8, and for periodic cleaning of the bottom 2 to 3 times -4 years of precipitation in the bottom wall of the tank 1 has a hatch with a lid 9. to establish regulated SNIP biogas digesters and pressure in the gas holders to the bell bottom 3 attached removable weights 10, which is assigned the weight given diameter and weight of the bells 3.

Bell rack guides and rollers 3, control devices and installing the insulation performance of the vessel 1 are not shown because their execution is possible in various embodiments.

Operation of the proposed wet gas tank of variable capacity must be carried out in compliance with the safety of wet gas tanks intended for combustible gas guide. This should be taken into account temperature and humidity loaded in the proposed wet gasholder discharged from the digester fermented mass continuously or intermittently, with its additional cooling in the heat exchanger when heating loaded in the digester to the fermentation of fresh weight or without cooling.

The main economic benefit from the use of the proposed invention wet gas tank of variable capacity is a significant reduction in the cost of its operation in the winter by eliminating the need to use steam-jet elevators and other technical means of heating known wet gas holders of variable capacity when using different fuel or electricity.
