| 20120017872 | RECIPROCATING PISTON LEAN METHANE GENERATOR - A reciprocating piston generator assembly that uses a low-concentration methane as a form of fuel comprises: a lean methane engine; a generator assembly; a fine water mist transmission system; a refrigerating dehydrator; an electric butterfly valve; a pressure regulator; a fuel-air mixer; a TEM controller; a heat load sensor; a combustion chamber for the lean methane engine; an air filter; and a speed governing butterfly valve, wherein the fine water mist transmission system is attached sequentially with the refrigerating dehydrator, electric butterfly valve and low-concentration methane engine; and the pressure regulator, fuel-air mixer, air filter, speed governing butterfly valve, heat load sensors and combustion chambers are installed in the methane engine; that the TEM controller is connected to the fuel-air mixer and heat load sensor; and the generator is connected to the low-concentration methane engine. This invention has been applied broadly in low-concentration methane coal mines and other similar fields due to its favored properties; such as high heat-recovery efficiency, lessened water consumption, energy savings, emission reduction and environmental protection. | 01-26-2012 |
| 20110281254 | METHOD AND APPARATUS FOR ANAEROBIC DIGESTION FOR CROP STALK - This disclosure discloses a process and an anaerobic digestion system for crop stalk/straw. The process in one example comprises (A) Feeding, (B) Heating and Digestion at the set temperature, (C) Discharging of Biogas, Sludge and Effluen{grave over ( )}t. The system in one example comprises (I) High Solid Content Digester (II) Hydro-Circulation Digester and (III) Stalk/Straw Feeder. Steps (A), (B) and (C) are accomplished in the devices (I) and (II). The step (A) is accomplished through the stalk/straw feeder (III), a special feeding mechanism, by which the crushed or smashed stalk/straw is pushed into the bottom of digester vessel. After being fermented or digested in the device (I), feedstock that is the mixture of biomass and water flows freely into the device (II) through the feedstock discharge outlet. The stalk feeder (III) is comprised of a hopper ( | 11-17-2011 |
| 20110250115 | METHOD AND ABATEMENT DEVICE TO DESTROY LOW-CONCENTRATION COALMINE METHANE - A method and an abatement device for destroying the low concentration coalmine methane is disclosed. Low concentration coalmine methane can be destroyed automatically by passing through the device described in the following process: (A) Heating the oxidization bed electrically till its temperature rises up to at least 800° C.; (B) Passing the airflow that contains low concentration coalmine methane into the oxidization bed, where the methane is oxidized quickly, releasing thermal energy; (C) Reserving of the thermal energy generated to maintain the reactions continuously; (D) Discharging of waste gas from the oxidization bed after oxidizing reaction; (E) Reversing airflow direction and passing the low concentration coalmine methane from the opposite direction into the oxidization bed, where methane is oxidized and releasing the thermal energy; and (F) Reserving and outputting excess thermal energy. These steps from (B), (C), (D), (E) and (F) are repeated. The device is comprised of a reversal valve mechanism, oxidization bed, recovery mechanism, gas inlet system, as well as monitoring and measuring system. The reversal valve mechanism is mounted in the oxidization bed and attached to the recovery mechanism and the gas inlet system, which are assembled as a whole package. The invention is featured with energy saving, environmental protection, high efficiency, safety, prompt and complete reaction and it is applied in the engineering project of destroying low concentration coalmine methane or other similar projects. | 10-13-2011 |
