Description
Technical field
the present invention relates to boiler waste gas process field, particularly a kind of boiler waste gas utilizes device.
Background technology
waste gas refers to that the mankind are at the poisonous and hazardous gas produced and discharge in life process.Particularly chemical plant, steel plant, pharmaceutical factory, and coking plant and oil plant etc., the waste gas smell of discharge is large, serious environment pollution and affect health.
the industrial waste gas of all kinds of manufacturing enterprises discharge is the important sources of atmosphere pollution.If large capacity industrial waste gas unprocessed up to standard after enter air, atmosphere quality must be made to decline, bring serious harm to health, bring about great losses to national economy.After in industrial waste gas, poisonous and harmful substance enters human body by respiratory tract and skin, long-term low concentration or the contact of short-term high concentration can cause the temporary and permanent pathology of the organs and systems such as the breathing of human body, blood, liver, and especially benzopyrenes polycyclic aromatic hydrocarbon can make human body directly carcinogenic to cause the great attention of the mankind.
industrial waste gas comprises organic exhaust gas and inorganic waste gases.Organic exhaust gas mainly comprises various hydro carbons, alcohols, aldehydes, acids, ketone and amine etc.; Inorganic waste gases mainly comprises oxysulfide, nitrogen oxide, oxycarbide, halogen and compound thereof etc.
the waste gas that current domestic boiler produces most of untreated be all directly be discharged in air, do not reach the boiler waste gas discharge standard of national regulation, severe contamination atmospheric environment, so not only make air contaminated, the energy contained in the waste gas also making boiler combustion discharge is not fully utilized, if by the waste gas recovery of boiler and produce power, then energy utilization rate can be improved, reduce expenses.
Summary of the invention
the object of this invention is to provide a kind of boiler waste gas and utilize device; by the heat energy recycle in the waste gas that produces after boiler combustion; and recovery utilization rate is higher; and purified treatment is again carried out to waste gas; purify more thorough; when improve energy utilization rate, accomplish again the protection to environment.
object of the present invention can be achieved through the following technical solutions:
a kind of boiler waste gas utilizes device, comprise cyclone dust collectors, heat-exchanging water tank, heat exchanger tube, filter chamber, desulfurization chamber, described cyclone dust collectors lower-left end connects boiler exit gas mouth by tube connector, upper right side connects the first air-introduced machine by wireway, the first described air-introduced machine other end is inserted from heat-exchanging water tank top by wireway, connect heat-exchanging water tank internal heat exchange tubes, described heat-exchanging water tank lower-left end connects boiler feed water mouth by drainpipe, described heat exchanger tube passes from heat-exchanging water tank bottom righthand side, connect lower-left, filter chamber end, the second air-introduced machine is connected by wireway on the right side of described upper end, filter chamber, the second air-introduced machine other end connects denitration chamber by wireway, wireway is inserted into desulfurization chamber inner bottom, described desulfurization chamber upper end arranges blast pipe.
described heat exchanger tube is arranged more than ten back bending place.
described filter chamber's inner upper end arranges filter, and intermediate inner wall arranges spray equipment, and lower end arranges sedimentation basin, and filter chamber arranges drainpipe on the right side of bottom.
described desulfurization chamber inside arranges calcium carbonate soln.
beneficial effect of the present invention: a kind of boiler waste gas of the present invention utilizes device; inside arranges heat-exchanging water tank; in heat-exchanging water tank, device is with the heat exchanger tube of multiple back bending place, can, effectively by the heat energy recycle in the waste gas that produces after boiler combustion, be cool water heating; recovery utilization rate is higher; and purified treatment is again carried out to waste gas, purification is comparatively thorough, when improve energy utilization rate; accomplish again the protection to environment, there is higher economic implications and social value.
