Abstract
A kind of coal gas pearl stone puffing furnace flue gas exhaust heat Application way is the high-temperature flue gas carrying fine perlite of 800 degrees centigrade of being discharged by pearl stone puffing furnace.By heat exchange of heat pipe, by air heat to more than 500 degrees Celsius.For rotary drying kiln drying perlite ore and heating gas, for the thermal source of pearl stone puffing furnace.The cooling high-temperature fume carrying expanded perlite enters whirlwind collector, carry out gas solid separation, flue gas that collecting granules perlite contains powdery expanded perlite discharges from whirlwind collector central tube, bag filter is sent into by air-introduced machine, pure qi (oxygen) enters air, powdery perlite reclaims and adopts the present invention, the available fume afterheat of pearl stone puffing furnace that makes is fully used, and realizes zero energy consumption of rotary drying kiln.Reduce the coal gas consumption more than 10% of pearl stone puffing furnace.
Description
Technical field
The invention belongs to environmental protection and energy saving technical field of resource utilization.Especially belong to a kind of coal gas furnace for expanding perlite fume afterheat Application way, be mainly used in coal gas furnace for expanding perlite fume afterheat and utilize and gas cleaning.
Background technology
Existing furnace for expanding perlite is divided into coal furnace, gas furnace and electric furnace by thermal source difference.Coal furnace is due to serious to atmosphere pollution, and stove is interior easily to crust, now few employing.Electric furnace energy consumption is high, can only production closed perlite.Gas furnace, can production perforate perlite due to energy-conservation, also can production closed perlite and being widely adopted.Fine perlite fume afterheat utilizes, China just began one's study as far back as the nineties in 20th century, but due to Application way, the reason of corollary equipment, utilization rate of waste heat is not high, application is not extensively along with the development of China's science and technology, a kind of heat changes exploitation and the black body radiation energy-saving coatings of the heat exchange of heat pipe of ultrahigh in efficiency, the exploitation of insulating mold coating, the appearance of novel rotation dry kiln, the technique that perlite expansion fume afterheat is utilized is more advanced, and system equipment composition is more reasonable, more scientific.Energy-saving effect is more remarkable.The technical program is innovated by integrated innovation and introduction digestion again, and a kind of coal gas furnace for expanding perlite fume afterheat Application way of proposition just belongs to one of them.
Summary of the invention
The object of this invention is to provide a kind of coal gas furnace for expanding perlite fume afterheat Application way, the water-cooled flue cancelling the outlet of former furnace for expanding perlite changes heat pipe air-gas-heat exchanger into, for high-temperature flue gas and expanded perlite cooling, produce high temperature (being greater than 500 degrees Celsius) air simultaneously and be used for the thermal source of rotary drying kiln and coal gas is heated.
What utilize rotary drying kiln to discharge has the high temperature air of more than 200 degrees Celsius for the combustion air of coal gas furnace for expanding perlite.
Adopt a kind of rotary drying kiln and bag-type dust removing system utilizing furnace for expanding perlite fume afterheat of my company designs.
The beneficial effect of employing the technical program is: utilize heat exchange of heat pipe, thermal conductivity factor height fume afterheat can be fully recycled.
High temperature air is adopted to be soaked with dust adhesion as the thermal source of rotary drying kiln and heating gas heating surface.Heat transfer efficiency is high, stable, freedom from repairs.
Adopt the process of malleation back air suction deashing dust cleaner containing powdery perlite flue gas, deduster structure is simple, invests low, powdery perlite light weight, ponders little little on fan life impact.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of process chart of coal gas furnace for expanding perlite fume afterheat Application way.
Detailed description of the invention
A kind of coal gas furnace for expanding perlite fume afterheat Application way of the present invention, detailed description of the invention again combined process flow chart is explained as follows further:
The coal gas that gas generator 1 produces sends into gas chamber 2, is used for the thermal source of rotary drying kiln 4 and expansion furnace 5 after high temperature air being carried out preheating to coal gas by the valve 12,13,14 on pipeline.
The high-temperature flue gas that puffing furnace 5 is discharged carries fine perlite and enters heat pipe parallel operation 6, carry out heat exchange, flue gas is lowered the temperature, air is heated, air after heating enters gas chamber 2 pairs of coal gas and heats, enter rotary drying kiln 4 to dry for perlite ore, by valve on pipeline 12,13,14, regulate coal gas and high temperature air amount.
Air blast 8 is for carrying whirlwind collector 7, and the graininess perlite of collection enters feed bin 9, and simultaneously for heat exchange of heat pipe provides cold air, its air quantity is regulated by the control valve 15,16 on pipeline.
High temperature (the being greater than 200 degrees Celsius) air that rotary drying kiln 4 is discharged enters expansion furnace 5 and makes combustion air.
What whirlwind collector 7 and particulate perlite feed bin 9 were discharged extracts the dedusting of feeding sack cleaner 11 containing the perlitic flue gas of powdery out by air-introduced machine 10, and pure qi (oxygen) enters air by sack cleaner top.Powdery perlite is discharged pack from sack cleaner ash bucket baiting valve and is recycled.
This kind of coal gas furnace for expanding perlite fume afterheat Application way, can be used for newly-built coal gas expanded perlite production line, also can be used for the transformation of original production line.
