Embodiment Construction

[0041]The present invention will be further described in detail below in conjunction with the embodiments of the drawings.

[0042]Such asfigure 1As shown, the pulverized coal gasification device of this preferred embodiment includes a gasifier, a waste water nozzle 1, a waste water buffer tank 2, a liquid feeding pipe 3, a heat exchanger 5, a booster pump 6, a filter 8, an air inlet pipe, etc. ,figure 1Middle e is the gasifier shell and water wall.

[0043]The gasification furnace has an ignition burner, a start-up burner, a process burner, and an interface for installing the aforementioned burners respectively, and the aforementioned burners are independently configured.

[0044]In this embodiment, the start-up burner is made to realize the combined functions of ignition and start-up, and the wastewater nozzle 1 is installed on the interface of the original ignition burner, that is, the ignition burner is no longer installed on the interface, and the interface is used to install the wastew...

Abstract

The invention relates to a pulverized coal gasification device and a process method for blending combustion of organic wastewater. The pulverized coal gasification device comprises a gasification furnace, the gasification furnace is provided with an interface capable of installing an ignition burner, the pulverized coal gasification device is characterized in that the pulverized coal gasificationdevice also comprises a wastewater nozzle, and the wastewater nozzle can also be installed on the interface. The original function of the interface is that the interface is used for installing an ignition burner and the wastewater nozzle at present, a gasification furnace does not need to be modified, a special waste liquid inlet does not need to be formed in the gasification furnace, and therefore the original connector of the gasification furnace is fully utilized to be combined with the newly-added waste water nozzle to atomize waste water.

Description

Technical field[0001]The invention belongs to the technical field of chemical industry, and specifically relates to a pulverized coal gasification device and a process method for blending organic wastewater.Background technique[0002]In recent years, with the rapid development of the petrochemical industry, a large amount of organic waste water is produced while producing various products. The waste water not only contains high concentrations of organic matter, but also contains toxic and harmful substances, which makes treatment difficult and costly. With the implementation of the new environmental protection law, how to efficiently treat organic wastewater has become an important issue facing enterprises.[0003]Organic wastewater is usually treated by biochemical or incineration methods. In the biochemical treatment method, the toxic and harmful substances in the organic wastewater can easily cause the inactivation of biochemical bacteria. It is necessary to build physical and chemi...
