Embodiment Construction

[0059] A feed-out gas ash removal device for clean utilization of coal according to the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0060] Such as figure 1 As shown, a feed and gas ash removal device for clean coal utilization includes a storage tank 3, an ash removal device 11 and a reaction kettle 12. The top of the storage tank 3 is connected to the conveying device 1 through the first valve 2; the bottom of the storage tank 3 It is connected to the screw device through the second valve 4 . The bottom end of the ash removal device 11 is connected to the feeding cylinder 7 , and the feeding cylinder 7 is connected to the screw device 5 through the third valve 6 . The reaction kettle 12 is sealed and connected with the feeding cylinder 7 through a metal compensator 8 and a dynamic and static sealing device 9 .

[0061] There are one or more storage tanks 3, which can be connected in series or in parallel. The...

Abstract

The invention provides a feed gas outlet ash removal device for cleaning utilization of coal. An inlet end of a storage tank is connected with a conveying device through a first valve; an outlet end of the storage tank is connected with a spiral device through a second valve; the lower end of an ash removal device is connected with a feeding cylinder,and the feeding cylinder is connected with thespiral device through a third valve; and the feeding cylinder is in sealing connection with a reaction kettle through a metal compensator and a dynamic and static sealing device. A feed device has theadvantages that the structure is simple,and continuous feed,continuous gas production,high-temperature efficient ash removal and continuous industrial mass production can be achieved. High valued petroleum,natural gas and water in the coal are separated out by cleaning pretreatment to obtain high-calorie anthracite under the situations of low temperature,no oxygen and no external water,and the anthracite can be further processed to obtain a high value-added novel coal-based material.

Description

technical field [0001] The invention relates to the technical field of coal energy saving and emission reduction, in particular to a feed and gas ash removal device for clean utilization of coal. Background technique [0002] China is a country with "more coal, less oil, and less gas". Among my country's proven petrochemical energy reserves, oil and natural gas account for only 6%, and the remaining 94% are coal substances. Such resource characteristics determine that China should build an energy structure based on coal. [0003] my country's coal use and reserves are dominated by low-rank coal, and coal contributes more than two-thirds of the total atmospheric emissions such as sulfur dioxide and nitrogen oxides. The clean and efficient use of coal has become a national strategy and an inevitable choice. There are two main directions for clean and efficient utilization, one is end treatment, ultra-low emissions after coal combustion, and the other is clean utilization at t...
