Abstract
The invention discloses an integrated fluid afterheat recoverer and belongs to heat exchange equipment, in particular a coke oven gas afterheat recovery device. The integrated fluid afterheat recoverer is characterized in that: connecting flanges are arranged at both ends of a thick-wall cast iron inner barrel respectively; a heat exchange tube is cast in the thick wall of the cast iron inner barrel; a heating medium inlet and a heating medium outlet are formed at both ends of the heat exchange tube; and the connecting flanges are connected with a rising tube socket and a bridge tube of a coke oven respectively. The integrated fluid afterheat recoverer has the advantages that: the heat exchange tube is cast in the thick wall of the inner barrel so that the heat exchange tube is integrated with the inner barrel; due to conducting heat exchange as a main heat exchange mode, the heat conducting efficiency is improved greatly; and by adoption of heat conducting oil as a heating medium, overpressure potential hazard due to phase change is avoided, and the safety is enhanced. The integrated fluid afterheat recoverer can effectively recover the afterheat carried by coal gas in a coal gas rising tube, has beneficial effects of reducing coking energy consumption, fully using energy and developing low-carbon economy, and has good economic and environmental benefits due to popularization and application.
Description
Technical field
The invention belongs to a kind of heat-exchange apparatus, particularly the coke-stove gas waste-heat recovery device.
Background technology
In the process of coking, heat more than 30% is arranged along with coal gas is overflowed through tedge,, the trial of different modes is arranged all both at home and abroad at present to the coke oven coke oven uprising tube waste heat recovery, but all do not have ripe experience, sum up mainly is the problem of low and these two aspects of poor safety performance of organic efficiency.The Chinese patent CN2595808 that the inventor formerly has " a kind of coke-stove gas tedge waste-heat recoverer " discloses a kind of form of water leg that adopts and has carried out waste-heat recoverer; because the refractory material protective layer is arranged on the recover inwall, it only is that 6-7% and bearing capacity are relatively poor that the thermal efficiency is reclaimed in the conduction of influence heat.Chinese patent CN201697501U " coke-stove gas tedge waste-heat recovery device " discloses a kind of two hollow semi-cylindrical coil pipes that are fastened on the tedge outer wall that comprise in addition, the buckling surface of two coil pipes is the heat transfer unit (HTU) of the tooth-shape structure that cooperatively interacts, though these device installation and removal are convenient, reduced the advantage of maintenance difficulty, but two sealing difficulties that fasten hollow semi-cylindrical coil pipe buckling surface are bigger.
Summary of the invention
In order to overcome the deficiency of existing coke-stove gas tedge waste-heat recoverer, the invention provides a kind of integral fluid waste-heat recoverer, big, safe and reliable advantage that this integral fluid waste-heat recoverer has the good airproof performance compressive resistance.
The technical solution adopted for the present invention to solve the technical problems is: a kind of integral fluid waste-heat recoverer, it is characterized in that: adpting flange is equipped with at heavy wall inner core two ends respectively, be cast with set of heat exchange tubes in the cast iron inner core heavy wall, the heating agent import and export are equipped with at the set of heat exchange tubes two ends respectively, and described adpting flange is connected with the rising base and the bridge tube of coke oven respectively.
Described heavy wall inner core outer wrapping heat-insulation layer and shell.
Heat exchanger tube in the described set of heat exchange tubes is shape or shell and tube arrangement in the shape of a spiral.
Described adpting flange and heavy wall inner core are cast into one.
Described adpting flange and heavy wall inner core are welded as a whole.
Heating agent in the described heat exchanger tube is a conduction oil.
The manufacture method of integral fluid waste-heat recoverer, it is characterized in that: the cast iron inner core adopts ordinary sand casting or centrifugal casting, conventional cast adopts horizontal type sand mould box or vertical sand mould box, described horizontal type sand mould box casting comprises the steps: that mainly a. makes set of heat exchange tubes, b. cast the heavy wall inner core, the set of heat exchange tubes inner chamber is placed the inner core sand mold, to guarantee the shape and the wall thickness of inner core, after the inner core sand mold fixes set of heat exchange tubes and inner core are together hung in the outer sand mold of folding up and down and cast, molten iron temperature should 3. weld adpting flange at 1200-1300 ℃ at the inner core two ends.
The method of described centrifugal casting is to use horizontal centrifugal casting machine, the resin sand pattern that adapts with the inner core external diameter is set in centrifugal reel to be fixed in the rotary drum in casting the rotation rotary drum with set of heat exchange tubes and to make molten metal at the centrifugal action lower charging type with solidify, obtain dense structure, the heavy wall inner core of good mechanical property.
High temperature coke oven coal gas flowing from bottom to top in the heavy wall inner core in the present invention, its waste heat that carries is heated to 400～600 ℃ to the cast iron inner core, because heat exchanger tube and cast iron inner core are cast into the one inner core and with conduction pattern heat are passed to heat exchanger tube, heat exchanger tube is managed interior heat-conducting oil heating with the conduction pattern handle equally, thereby reaches the purpose of waste heat recovery.Heat exchanger tube has the alumina silicate felt to be incubated outward, and heat-insulation layer has shell protection outward, and waste-heat recoverer up and down adpting flange can be respectively be connected with rising base and bridge tube on the coke oven.
The invention has the beneficial effects as follows because set of heat exchange tubes is cast in the inner core heavy wall, heat exchanger tube and inner core are integral, with the conduction heat exchange is main heat exchange mode, and because heavy wall inner core intensity height, good corrosion resistance, its inboard need not to be provided with refractory masses, heat transfer efficiency is improved greatly, can reach more than the 12--15% according to test heat recovery efficiency of the present invention, can satisfy the energy demand in postprocessing working procedures such as refining benzene workshop, it is heating agent that heat exchanger has adopted conduction oil, effectively avoided causing superpressure hidden danger because of the phase transformation gasification, simultaneously because heat exchanger tube is assembled detection in advance, security is greatly improved, in use as can directly clear up the service life that can not influence equipment when phenomenon such as inner core coking occurring.The present invention can effectively reclaim the waste heat that carries through the coal gas in the gas up take, to reducing the coking energy consumption, makes full use of the energy and has good effect with the development low-carbon economy.It applies good economic benefit and environmental benefit.
