Embodiment Construction

[0012] Such as figure 1 , figure 2 and image 3 As shown, the regenerative ultra-low calorific value gas treatment and energy utilization device includes the main body of the device, the periodic reversing air flow pipeline and the measurement and control system. The main body 1 of the device consists of a shell 2, a porous plate A3, a regenerative heat exchanger 4, a partition A5, a porous plate B6, a combustion chamber 7, a porous medium packed bed 8, a small-porosity foam ceramic 9, and a large-porosity foam ceramic 10. It is composed of a smoke suction device 11 , a valve 12 of the smoke suction device, a perforated plate C13 , an ignition space 14 , a burner 15 and an insulating layer 16 . The partition B30 divides the bottom airflow channel into the bottom airflow channel A23 and the bottom airflow channel B24. Bottom air flow channel housing 26 and partition B30 support perforated plate A3, and porous plate A3 holds up two regenerative heat exchangers 4 arranged sym...

Abstract

The invention discloses a heat accumulation type super-low calorific value fuel gas treatment and energy utilization device, which is applied to reciprocal flow heat accumulation type combustion technology of the super-low calorific value fuel gas in industrial production. The device consists of a device body, a periodic reverse gas flow circulating pipeline and a measurement and control system. The self-maintenance combustion of super-low calorific value fuel gases with extremely low methane concentration, such as coal mine methane, gases produced in municipal solid waste landfill, combustible gases produced during pyrolysis and smolder (such as battery heating) of biomass in nature and in the lives of human society and the like, can be realized in the device; and because the aperture of low-porosity porous medium filled in a porous medium packed bed of a combustion chamber is less than the quenching diameter, the combustion can be controlled within the combustion chamber. In addition, a part of heat produced by the combustion of the super-low calorific value fuel gas is pumped out by a smoke suction device and conveyed to the conventional exhaust heat boilers for heating water for heating or producing super-heated steam for power generation; and thus the device has the advantages of energy conservation and environmental friendliness.

Description

technical field [0001] The invention relates to a reciprocating flow regenerative combustion device for ultra-low calorific value gas in industrial production, in particular to a reciprocating flow regenerative combustion device with energy recovery and utilization. Background technique [0002] Gas fuel is divided into high, medium and low calorific value gas according to the combustion calorific value, but there is no clear regulation on ultra-low calorific value gas. Usually, the combustible component is mainly methane gas, and the concentration value is between 0.1% and 5%. For example: mine Mixed gases such as exhaust air, petrochemical natural gas industrial waste gas, landfill gas and biogas are collectively referred to as ultra-low calorific value gas. Due to the low methane content of ultra-low calorific value gas, it is difficult to be utilized by conventional combustion technology, and most of it is directly discharged into the atmosphere, causing huge energy wast...
