Abstract
The utility model's heat-exchange pipe is arranged in an upright smoke carboy axially. The both ends of the heat-exchange pipe, bending wiht radial radiation, is connected with a plenum chamber of the smoke carboy's external wall, with the windward side of the joint having a copying changeable anti-abrasion cover. The heat-exchange pipe has a position-controlled ring, and s taper-capping cylinder is arranged in the middle of the smoke carboy, wiht the taper point pointing to a smoke inlet, and the tail being a free end. A high-temperature dust-laden smoke flows across the smoke carboy with a high speed from up to down, and a cold air flows through the heat-exchange pipe from down to up. The utility model has a high coefficient of convective heat transfer and little deposition, with the advantages of porper structure, small volumn, small area-taking, favorable solidness and durableness, and high heat-exchange efficiency.
Description
The utility model is relevant with general heat exchange, and especially directly the air heater of contact is not relevant with thermal medium.
Traditional heat-exchange device that is used for ash-laden gas and air needs the air of preheating flow through coiled pipe or wing pipe etc., and these tube bundle lateral arrangement are in the tube that flue gas is flowed through.The ash-laden gas transversal flow tube bundle of heat, the positive wash surface of tube bundle is big, very easily wearing and tearing, the life-span of heat exchanger is short.Easy dust stratification dirt is reduced about 20% by the tube bundle coefficient of heat transfer after staiing on the heat exchanger tube.The path of more serious meeting obstruct smoke.The spy sets up deashing device for this reason, improves energy consumption, nonetheless can not solve the dust stratification problem.
The purpose of this utility model provides a kind of heat exchange efficiency height, and volume is little, and floor space is little, rational in infrastructure, durable novel flue gas-air heat exchanger.
Axial arranged heat exchange tube bundle in the utility model flue gas tube.Flue gas drum outer wall two ends have annular cold respectively, the hot-air plenum chamber, and the heat exchanger tube two ends communicate with cold and hot plenum chamber respectively, and its junction is radially the width of cloth and penetrates arc.Inlet of cold air pipe and hot gas outlet duct have several passages to be communicated with hot and cold air plenum chamber respectively.Flue gas tube shell and plenum chamber junction are segmental arc, and there is expansion joint at the gas approach place.
Be to improve the flow velocity of flue gas in heat exchanger, an axial cylinder is established at flue gas tube middle part, and the cylinder top is the acute angle circular cone sensing gas approach that binds, and the cylinder afterbody is a free end, and the cylinder body has supporting member to link to each other with the flue gas barrel.
Because the wearing and tearing of heat exchanger tube segmental arc windward side are big, therefore be provided with the detachable profiling abrasionproof lid that changes at every heat exchanger tube wash surface.Because heat exchanger is generally level transportation, assembling, the vertical use for preventing every heat exchanger tube generations degree when level is parked, set up the heat exchanger tube position-controlled ring again, not only controlled but also can freely stretch of heat exchanger tube.
Workflow of the present utility model is as follows: the high temperature dust flue gas, flows out from the bottom behind the smooth heat exchanger tube absorbing and cooling temperature of heat exchanger inside with every layout of monomer from top to down with flow at high speed.Cold air is through the cold air air inlet pipe, and the cold air plenum chamber enters in every heat exchanger tube of monomer, flows to going up down, and after the heat that absorbs the high temperature dust flue gas simultaneously improved temperature, from top hot-air plenum chamber, the hot-air escape pipe was discharged.
The utility model is worked in the partition mode, and cold and hot fluid is parallel adverse current in heat exchanger, and cold air can be heated to higher temperature and heat exchanger volume is less.The dust-laden high-temperature flue gas from top to bottom with the heat exchanger tube PARALLEL FLOW, vertical wash surface is little, whole heat exchanger dust stratification is few, the reduction influence of heat exchanging efficient is little, and the inner barrel structure makes flue gas flow rate big as far as possible, has improved the coefficient of heat transfer, and the utility model is vertically arranged, to aerial development, reduced floor space as far as possible.All there is the enough big bend pipe of radius of curvature at all heat exchanger tube two ends to solve the problem of expanding with heat and contract with cold of every single tube; Segmental arc is established respectively with cold in the outer cover of heat exchanger two ends, and hot plenum chamber connects to solve shell and heat exchanger tube nonsynchronous problem that expands; A total expansion piece is established at the overall top of heat exchanger, with the problem of expanding with heat and contract with cold after solving whole heat exchanger and external pipe and basis being connected.The heat exchanger tube segmental arc that facings the wind has protector.Reasonable integral structure has improved service life.

Following is embodiment of the present utility model:
Flue gas tube 1 two ends outer wall of the present utility model has annular cold air plenum chamber 3, hot-air plenum chamber 5 respectively.Evenly staggered axially-aligned on three equidistant concentric circumferences of heat exchange tube bundle 7 in heat exchanger tube.The heat exchanger tube two ends communicate with hot and cold plenum chamber respectively, and its junction is radially the width of cloth and penetrates arc.Cold air air inlet pipe 2 and hot-air escape pipe 4 have two passages of symmetry to communicate with hot and cold air plenum chamber respectively.Flue gas tube 1 shell and plenum chamber junction are segmental arc 8.There is expansion joint 6 at the gas approach place.
There is axial cylinder 9 at flue gas tube middle part, and its circular cone that binds points to gas approach, and the cylinder afterbody is a free end, and the cylinder body has cramp bar 10 to weld with cylinder and flue gas barrel respectively.Be welded with position-controlled ring 11 on the cramp bar.Position-controlled ring is placed on the heat exchanger tube 12, controls the position but delocalization, the heat exchanger tube retractable.
Be welded with alignment pin 14 on the heat exchanger tube segmental arc 13.On the abrasionproof lid 15 two strip holes 16 that cooperate with alignment pin are arranged.Abrasionproof lid and segmental arc 13 profiling covers can be changed thereon at any time.
