Abstract
The invention relates to a gasification anthracite coal gas purification and cooling process in gas generator comprising the follow steps: firstly high temperature coal gas produced by the gas generator is dusted primarily in a gravity dust collecting equipment to remove large particle dust in the coal gas, then the coal gas high temperature sensible heat is recycled and at the same time the gas temperature is cooled after the coal gas in a waste heat recoverer, the coal gas temperature is further indirectly cooled when the coal gas is out of the waste heat recoverer and in a wind cooling machine, after cooling the coal gas is purified by removing most dust in the coal gas in an electrostatic precipitator, the deep purified coal gas is deeply cooled in an indirect cooler, finally the coal gas is conveyed to users through a coal gas supercharging equipment. The invention implements to convey low water content dry coal gas to clean gas pipe network, improves the gas generator conveying efficiency and burning temperature, avoids the water contamination problem of direct contact of coal gas and water and reaches energy-saving effect through waste heat recovery to high temperature coal gas during the gas cooling process.
Description
Technical field:
The present invention relates to a kind of producer gas generator and purify process for cooling, particularly a kind of gas purification and cooling process of gas generating furnace gasified anthracite.
Background technology:
At present, one section producer gas generator washing process of the general employing of domestic smokeless coal gasification, a large amount of waste heats in the coal gas of high temperature are washed water and absorb, and cause this part energy to be wasted.Because washing water directly contact with coal gas, cause washing water extremely stagnant; Make again simultaneously and carry a large amount of moisture content in the coal gas secretly, washing water directly contact with coal gas, and the water of condensation that is produced is the principal pollutant of gas station, bring the tight problem of environmental pollution that gets.
Summary of the invention:
The objective of the invention is to overcome the deficiency of background technology and a kind of gas purification and cooling process of gas generating furnace gasified anthracite is provided.
The present invention adopts following technical scheme:
A kind of gas purification and cooling process of gas generating furnace gasified anthracite, its technical process is: the coal gas of high temperature of being produced by producer gas generator at first enters gravitational dust collection equipment and carries out elementary dedusting, big dust particle in the coal gas is removed, then, enter waste-heat recoverer, the coal gas high-temperature sensible heat is recycled, reduce gas temperature simultaneously, after coal gas goes out waste-heat recoverer, enter air cooler, utilize outside air that coal gas is carried out further cooling indirectly, cooling back coal gas enters electrostatic precipitator, remove most of dust in the coal gas, coal gas is purified, and the coal gas behind the deep purifying enters indirect cooler again, carries out degree of depth cooling, at last, coal gas is delivered to the user by the coal gas supercharging equipment.
Technical scheme of the present invention compared with prior art, realized carrying the very low dry gas of water content to the purified gas pipe network, increase substantially the purpose of producer gas generator coal gas transport efficiency and raising temperature of combustion, the gas generating station water pollution problems of having avoided coal gas and water directly to contact cooling being brought, to the waste heat recovery of coal gas of high temperature, reached energy-saving effect in the coal gas process of cooling.
Description of drawings:
Fig. 1 is a process flow sheet of the present invention.
Embodiment:
Below in conjunction with drawings and Examples in detail the present invention is described in detail:
A kind of gas purification and cooling process of gas generating furnace gasified anthracite, referring to accompanying drawing 1, its technical process is: the coal gas of high temperature of being produced by producer gas generator at first enters gravitational dust collection equipment and carries out elementary dedusting, big dust particle in the coal gas is removed, then, enter waste-heat recoverer, the coal gas high-temperature sensible heat is recycled, reduce gas temperature simultaneously, after coal gas goes out waste-heat recoverer, enter air cooler, utilize outside air that coal gas is carried out further cooling indirectly, cooling back coal gas enters electrostatic precipitator, removes most of dust in the coal gas, and coal gas is purified, coal gas behind the deep purifying enters indirect cooler again, carry out degree of depth cooling, last, coal gas is delivered to the user by the coal gas supercharging equipment.
Present embodiment has been realized carrying the very low dry gas of water content to the purified gas pipe network, increase substantially the purpose of producer gas generator coal gas transport efficiency and raising temperature of combustion, the gas generating station water pollution problems of having avoided coal gas and water directly to contact cooling being brought, to the waste heat recovery of coal gas of high temperature, reached energy-saving effect in the coal gas process of cooling.
