Method and device applied to heating influent by virtue of efficient anaerobic reactor

Abstract

The invention provides a method and a device applied to heating influent by virtue of an efficient anaerobic reactor. The device mainly comprises a material inlet pool, the efficient anaerobic reactor and a heat pump unit, wherein the material inlet pool, the efficient anaerobic reactor and the heat pump unit are connected with one another sequentially; the heat pump unit consists of an evaporator, a compressor, a condenser and an expansion valve, and the evaporator, the compressor, the condenser and the expansion valve are connected with one another by virtue of a refrigerant pipeline to form a closed circulation system; a water inlet pipe of the material inlet pool is connected with a water inlet of the condenser, a water outlet of the condenser is connected with the material inlet pool by virtue of a pipeline, and a water outlet system of the efficient anaerobic reactor is connected with the evaporator by virtue of a pipeline. The method and the device have the beneficial effects of 1, remarkable environmental protection benefit; 2, energy saving, and consumption lowering; 3, economy and reliability in running; and 4, good social benefit.

Description

technical field [0001] The invention belongs to the field of energy saving and environmental protection, and in particular relates to a method and a device for heating the inlet water of a high-efficiency anaerobic reactor. Background technique [0002] Energy and environment are two major themes of sustainable development. Since the beginning of the new century, with the growth of population, the improvement of economic level and the progress of society, the energy crisis has been deepening, and the pollution and destruction of the ecological environment have also been intensified. With global energy consumption growing at a rate of 5% per year, fossil fuels are expected to last for one to two hundred years, and the world's energy situation is grim. my country's per capita energy is poor, and the per capita possession is only 1 / 2 of the world average and 1 / 10 of the United States. With the rapid development of the economy, the problem of energy shortage is becoming more a...

Problems solved by technology

[0004] However, in the northern region, due to the cold weather in winter and the low outdoor temperature, the stable temperature required for mesophilic anaerobic fermentation cannot be guaranteed if general warming and heat preservation measures are not taken for the anaerobic reactor.

At present, most of the heat energy required by anaerobic reactors is supplied by combustion of coal, oil or natural gas, which will inevitably lead to energy reduction and environmental pollution.
