Embodiment Construction

[0041] The idea, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the present invention.

[0042] Such as figure 1As shown, the dried and crushed oil shale is mixed with organic solid waste in a certain proportion and then sent to silo 1, then descends into carbonization furnace 2, and low-temperature carbonization produces combustible gas, oil vapor and solid waste semi-coke. The combustible gas and oil vapor leave the top of the carbonization furnace 2 and are separated into combustible gas and oil by the oil-gas separation device 3. The combustible gas is purified by the gas purification device 6 and stored in the gas storage tank 7, and the oil is stored in the oil tank 4; The feeder 15 enters the circulating fluidized bed boiler 14 for combustion; the gas storage tank 7 divides the combustible gas into three parts: ...

Abstract

The invention discloses a polygeneration utilization system of oil shale associated with organic solid waste, comprising a silo, a carbonization furnace, an oil tank, an oil-gas separation device, a gas purification device, a high-temperature gas heating furnace, a gas storage tank, and a gas combustion low-temperature gas heating furnace, gas turbine, heat exchanger, chimney, steam turbine, circulating fluidized bed boiler and feeder; dry distillation using a mixture of oil shale and organic solid waste. The invention also discloses a process, the step of which is to divide the combustible gas into three parts by the gas storage tank: one is used as the gas heat carrier; the other is used as the fuel to burn in the gas burner to generate high-temperature flue gas for heating the gas in the high-temperature gas heating furnace Gas heat carrier; thirdly, it is sent to the gas turbine for combustion, and the high-temperature flue gas produced after doing work enters the low-temperature gas heating furnace to heat the gas heat carrier. The invention mixes oil shale and organic solid waste to dry distillation, increases the output of combustible gas, and realizes the purposes of combustible gas combustion for heat supply, mass transfer and heat transfer.

Description

technical field [0001] The invention belongs to the technical field of oil shale resource utilization, and in particular relates to a polygeneration utilization system of oil shale accompanied by organic solid waste and a process thereof. Background technique [0002] Oil shale is an important unconventional oil and gas resource with huge reserves. After pyrolysis in a retort device at 400-600 °C, shale oil with properties similar to natural oil can be obtained. In the era of tight crude oil supply in the world, it has been As a very important petroleum supplementary energy. At present, the world's proven shale oil reserves are more than 400 billion tons (calculated based on in-situ reserves of oil shale), far higher than the world's proven recoverable reserves of crude oil. my country is a country with large reserves of oil shale resources. The proven reserves of oil shale resources are 719.937 billion tons, and the reserves converted into shale oil are 47.644 billion tons...
