Изобретение относитс к очистке сточных вод, а именно к получению метана из органических матерталов анаэробиым сбраживанием.The invention relates to the treatment of wastewater, in particular to the production of methane from organic materials by anaerobic digestion.

Известны способ и устройство дл обработки органического материала, предусматривающие наполнение и анаэробное сбраживание отходов животных в регулируемых темлерату жых услови х 1.A method and apparatus for treating organic material are known, which provide for the filling and anaerobic digestion of animal waste under controlled temperature conditions 1.

Недостатком такого устройства дл обработки Органического материала вл етс иевозможность поддержани стабипшой температуры по всему объему.A disadvantage of such an apparatus for treating organic material is the ability to maintain a stable temperature throughout the volume.

Наиболее близкой к предлагаемой вл етс система термостатировани метантенка, содержаща сосуд дп выделени горючих. газов, образованных при бактериальном расложении органических мате{Я1алов, расположенный & воде и в котором поддерж ва етс температура 20-37,8° С. 2.Closest to the present invention is the temperature control system of the digester, containing a vessel dp for the release of combustible. gases produced by the bacterial expansion of organic mate {H1alov, located & water and in which the temperature is maintained at 20-37.8 ° C. 2.

Недостатком известной системь вл етс низка эффективность процесса сбраживани из-за длительного протекани процесса при температуре 20-37.8° С, так как в такихA disadvantage of the known system is the low efficiency of the fermentation process due to the long course of the process at a temperature of 20-37.8 ° C, as in such

услови х имеет место мезофальиое брожение, дп которого характериы малые скорости. Целью изобретени вл етс повышение зффективности процесса брожени путем обеспечени термофильного режима брожени .conditions, mesophilic fermentation takes place, dp of which is characterized by low velocities. The aim of the invention is to increase the efficiency of the fermentation process by providing a thermophilic fermentation regime.

В качестве аккумулирующего вещества могзгг бьггь, например, испол1 ованы следующие вещества: парафин, магний сернокислый, кобальт азотнокислый.For example, the following substances are used as an accumulating substance: paraffin, magnesium sulphate, cobalt nitrate.

Claims

The goal is achieved by the fact that the system is equipped with a solar heater with heat carrier and pipelines for it, the tank of the digester is equipped with a hollow shell filled with accumulating substance, with coolant channels connected to the solar heater, the system is also equipped with two heat exchangers, the first of which is the reservoir pipe 20 leads the input of raw sludge and the output of decomposition products, and the second - with pipelines of raw sludge and heat carrier of the solar heater. In the drawing, a schematic representation of the temperature control system of the digester is presented. Resource j is enclosed in a hollow shell 2 with channels 3 for heat transfer fluid and filled with accumulating substance 4. The system additionally contains heat exchangers 5, with pipeline 6 D71 of fresh organic material and reservoirs for decomposition products, heat exchanger 8, pipeline 6 for fresh organic material and pipe 9 for the coolant, communicated in a closed loop with the solar heater 10 and the reservoir 1. The temperature control system operates as follows. Fresh organic material, preheated in heat exchanger 5 from decomposition products entering through conduit 7 from reservoir 1, is fed through conduit 6 to heat exchanger 8, where it is heated from a heat carrier connected in a closed loop by a pipe 9 to a solar heater 10 and with channels 3 heat carrier located in the hollow shell 2 to a temperature of 53-55 ° C, then fed for digestion to the resolvent 1. The temperature of 53-55 ° C is maintained using an accumulating substance 4, which is filled with a floor shell 2 reserve heat 1. The storage substance 4 is heated by the coolant to the melting temperature, after which the heat is absorbed at a constant temperature until the entire volume of the storage substance is melted. The technical advantages of the proposed temperature control system of the digester are to ensure a stable temperature regime that provides a thermophilic fermentation of organic material and heat savings due to the use of heat decomposition products and solar heating system. The invention The temperature control system of the digester, containing the digester reverser, accumulator for maintaining a certain temperature, entering the raw sludge pipeline and discharging decomposition products, which in order to improve the fermentation process by providing a thermophilic mode, it is equipped with a solar heater with heat carrier and pipelines for it, the tank of the digester is equipped with a hollow shell filled with the accumulating substance, with channels for the coolant, with Generalized with a solar heater, the tower is also equipped with two heat exchangers, the first of which is connected to the tank with raw sludge feed pipelines and decomposition products, and the second with raw sludge pipelines and solar heater coolant.
