Embodiment Construction

[0038] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0039] Before the high-concentration organic waste liquid enters the incineration equipment, it undergoes pretreatment processes such as filtration and evaporation concentration, enters the incineration equipment through a spray gun for high-temperature combustion, enters the steam superheating system and waste heat recovery system for waste heat recovery, and then undergoes non-catalytic reduction (SNCR) Combined with selective cat...

Abstract

The invention relates to a comprehensive processing system applied to coal-derived ethylene glycol exhaust gas / liquid for recycling and ultra-clean emission. Methyl nitrite (MN) section waste gas, methanol rectification waste gas, pressure swing adsorption (PSA) waste gas, methyl formate (MF) light distillate waste gas, MF waste liquid and accompanying-combustion gas are all atomized through a spray gun and are delivered into incineration equipment; flue gas of the incineration equipment firstly passes through a selective non-catalytic reduction (SNCR) denitration section for denitration, andthen passes through a waste heat recovery system, a selective catalytic reduction (SCR) denitration section and an air preheater to realize waste heat recovery, and finally, ultra-clean emission is realized. According to the system, ultra-low nitrogen combustion of the high-concentration waste gas / liquid is realized by employing a fractional combustion technology, and an SNCR and SCR combined denitration technology is employed to realize ultra-clean emission of NOx of the high-concentration waste gas / liquid; the waste heat recovery system is utilized to recover high-temperature and medium-temperature flue gas waste heat for power generation and user production; the SCR denitration temperature is reached after medium pressure steam is by-produced from the flue gas, and the waste liquid spray gun and flue gas dust removal function are improved; and the entire system is safe to operate, high in operating efficiency and high in energy utilization rate.

Description

technical field [0001] The invention relates to the technical field of waste gas and liquid treatment, in particular to a comprehensive treatment system applied to resource utilization of waste gas and liquid in a coal-to-ethylene glycol process to realize ultra-clean discharge. Background technique [0002] In the coal-to-ethylene glycol (EG) process, MF waste liquid will be generated at the top of the methyl formate (MF) separation tower in the dimethyl oxalate (DMO) rectification section. The main components of the waste liquid are MF, methyl nitrite ( MN), dimethoxymethane (ML) and methanol (ME). With the rapid development of industrialization and the country's emphasis on environmental protection, the country has intensified the investigation and punishment of corporate environmental protection, and chemical companies are facing the threat of shutdown due to the increasing pressure of environmental protection. [0003] Incineration treatment is the preferred way to sol...
