Technical field
The utility model belongs to the heat-obtaining technical field of the weary wind-heat counter flow oxidation device that is used for coal mine to ventilate mash gas, chemical emission comprehensive utilization field, is specifically related to a kind of weary wind oxidation unit heat exchanger that will lack the general mood body in weary wind oxidation unit internal-response liberated heat taking-up.
Background technology
Weary bellows chamber is drawn together nail alkane concentration and is lower than the industrial tail gas that industries such as 1% mine ventilation gas and chemical industry, papermaking, wastewater treatment contain fuel gas.It is the discharging in atmosphere directly, on the one hand, has aggravated atmosphere pollution, has caused greenhouse effects; Caused the serious waste of limited non-renewable resources on the other hand, only annual its low heat valve of gas that discharges from coal mine methane stream is equivalent to the low heat valve of 3,370 ten thousand tons of standard coals.Therefore, carry out weary wind and utilize technical research,, improve atmosphere quality, have very important significance for effectively utilizing existing resource and reducing greenhouse gas emission; Can promote simultaneously China's response environment and change and contractual capacity, improve the environmental protection equipment technical merit, promote the Environmental Protection in China industry development.
Weary wind use device is divided into hot reverse-flow oxidation unit and catalytic oxidizing equipment from principle, by oxidation unit, makes the gas generation oxidation reaction with caloric value in the weary wind produce heat energy, makes waste gas not useless.This just needs the reliable heat-obtaining of cover system.Heat exchanger is the visual plant of heat-obtaining system, and its operation principle has the equipment that transmits heat between the fluid at differing temperatures at two or more in brief exactly.At present, the domestic industry stove is used general with the technology maturation of heat-exchange device.But about the application technical research blank out of heat exchanger in weary wind oxidation unit.Temperature is up to more than 1000 ℃ in the weary wind oxidation unit oxidation bed, and the heat exchange method of heat exchanger in oxidation bed is not simple contact heat-exchanging, also has heat convection and radiation heat transfer, the heat exchange method complexity.We can say heat-obtaining system and design of heat exchanger rationally whether, direct relation the height of the weary wind oxidation unit thermal efficiency.How guaranteeing the safe and reliable taking-up of heat that the ventilation air gas oxidation reaction produces, is the purpose that we study.
The utility model content
The purpose of this utility model is innovative design and the weary wind oxidation unit heat exchanger of a kind of safe, reliable, efficient weary wind-heat counter flow oxidation device heat-obtaining system is provided.
The utility model is realized by following technical scheme:
Be a kind of weary wind oxidation unit heat exchanger, it is characterized in that comprising many group heat exchanger tubes, described heat exchanger tube is made up of parent tube and fin.
Described fin is square circular or oval or other shape.
The utility model comprises following two kinds of schemes when being applied in the oxidation bed that lacks the wind oxidation unit:
A kind of heat exchanger tube is the U type, and many heat exchanger tubes are in parallel to be used, and is laid in the oxidation bed of weary wind oxidation unit, and water inlet end, water side are positioned at the same side of oxidation bed, during installation and level keep a minute angle, make into and out of water end (W.E.) to be higher than U type end.
A kind of heat exchanger tube is a straight tube structure, and many in parallel uses of heat exchanger tube are laid in the oxidation bed of weary wind oxidation unit, and water inlet end, water side lay respectively at the oxidation bed both sides, and the water side is higher than water inlet end, so that the discharge of air.
Major advantage of the present utility model and beneficial effect are:
(1) parent tube is provided with fin outward, has guaranteed heat exchange efficiency.
(2) can be implemented in the interior even layout of whole device oxidation bed cross section.
(3) the in parallel use of many group heat exchanger tubes guarantees the cooling water flow distributed uniform.
(4) inclination one minute angle is installed, and assurance heat exchanger inner air tube is in time discharged, and has avoided the booster phenomenon.
(5) the pipe number of strokes may is few, has significantly reduced flow path resistance.
Use the utility model can guarantee that each heat exchanger cooling water flow is evenly distributed in the whole oxidation unit, the interior heat exchange of whole horizontal device cross section is even, uniform distribution of temperature field, and guarantee that heat exchanger is safe and reliable, avoid the generation of booster phenomenon.
