Description

A kind of time condensation heat exchanger on burnt gas wall hanging furnace
Technical field
This utility model relates to heat exchanger technology field, a kind of secondary condensing heat on burnt gas wall hanging furnace Exchanger.
Background technology
Conventional gas wall-hung boiler is commonly provided with the related device such as combustor, heat exchanger, utilizes heat exchanger to absorb combustion gas Produced energy, passes to be flowed through the cold water of heat exchanger by water inlet pipe, and after heat exchange, water temperature raises, and hot water is from water outlet bank of tubes Go out, it is achieved the function of flow heated water;The high-temperature flue gas that burning produces is extracted out outdoor by blower fan through tobacco pipe room.Owing to flue gas band becomes deformed When big part energy, the thermal efficiency causing wall-hung boiler is limited, and heat utilization ratio is difficult to promote.For these people at conventional gas Setting up a set of smoke secondary condenser system on the basis of the heat exchanger of wall-hung boiler, combustor heats main heat exchange by combustion gas Device, produces high-temperature flue gas, is pumped into smoke chamber through blower fan, and cold water enters time condensation heat exchanger from water inlet pipe and absorbs combustor High-temperature flue gas heat preheating current, the simultaneously cooled flue gas produced, separates out condensed water and inorganic salt.Condensing gas wall hanging stove Make use of flue gas heat flow heated water, make heat utilization efficiency greatly improve.
At present, on market, each parts of the heat exchanger assembly of secondary condensing heat exchanger are mostly to be spliced by solder technology Form, such as the Chinese utility model patent of Application No. 200820049039.2, disclose one " gas heater condensing Heat exchanger ", this heat exchanger have employed multipipe structure, and employs copper as producing material.Although heat can be substantially met The requirement of exchange, but these exchanger arrangement parts are more, complex manufacturing, and the production cycle is long, produces material valuable, cost It is difficult to be effectively controlled.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, it is provided that a kind of simple in construction, the thermal efficiency are high And the time condensation heat exchanger on burnt gas wall hanging furnace that production cost is low.
To achieve these goals, the technical solution adopted in the utility model is: a kind of on burnt gas wall hanging furnace two Secondary condensate and heat exchanger, it is characterised in that: include shell, spiral heat-exchange tube, flue gas partition baffle, water inlet connection and Water outlet joint, offers air inlet and air outlet, outside spiral heat-exchange tube, flue gas partition baffle are arranged on shell In shell and flue gas partition baffle is arranged in the middle of spiral heat-exchange tube, the two ends of spiral heat-exchange tube respectively with water inlet connection It is connected with water outlet joint.
Further, the body cross section of described spiral heat-exchange tube is run-track shaped.
Further, described ectosome is made up of housing and cover plate, and described water inlet connection and water outlet joint are arranged on lid On plate, described air inlet and air outlet are opened on housing.
Further, described spiral heat-exchange tube is made up of USU304 or USU316 stainless steel material.Described flue gas Partition baffle is made up of USU304 or USU316 stainless steel material.
The beneficial effects of the utility model are: simple in construction, with short production cycle and low cost, by being arranged on spiral heat exchange Flue gas water conservancy diversion shim in the middle of pipe, flue gas enters housing energy, it is possible to quickly shunts according to the water conservancy diversion direction of deflector, fills Discharging after dividing heat exchange, heat exchange efficiency is high.
Specifically there is following features: (1) utilizes single independent coil pipe pipe fitting as heat exchange main part, solderless contact, evades Because the product failure caused is corroded in welding position;(2) heat-exchange tube cross section is track type structure, and pipe fitting arrangement is tightr, changes Hot side is long-pending big, and the thermal efficiency is high;(3) product is without processing through surface anticorrosion, with short production cycle, low cost;(4) flue gas water conservancy diversion separates Sheet and casing assembly interact, and make high-temperature flue gas according to the orderly flowing of the arranged direction of heat exchange pipe fitting, improve heat exchange Efficiency;(5) with USU304 or USU316 rustless steel as base material, it is ensured that the Corrosion Protection of product, also reduce product simultaneously The material cost of product;(6) compact conformation is reasonable, manufactures the simplest, it is adaptable to the fuel wall hanging formula boiler on market.
