The effect of dry coke quenching feed water preheater is the temperature in order to further decrease dry coke quenching recyclegas, improves boiler and gives
Coolant-temperature gage plays the role of reduction energy consumption, improves dry coke quenching coke quality.
Chinese patent 200320128619.8 discloses a kind of dry coke quenching heat of the application of heat pipe in dry coke quenching field
Tubular type feed water preheater.Including gas tank, water side header, tube sheet, casing, heat pipe, tube sheet by cabinet be divided into gas tank and
Water side header, heat pipe are inserted between gas tank and water side header, and bringing-up section is known as in gas tank, is claimed in the header of water side
For cooling section, water side header is interior to be equipped with casing, and heat pipe cooling section is inserted in casing, by heat pipe for thermal conductivity by heat transfer, conducts heat
Amount is big, and the thermal efficiency is high.But the device heat exchange mode is single, cooling section is arranged in heat pipe, so that equipment volume and weight increase；
Equipment is overall structure again, and there are dew point corrosion phenomenons, and when flue-gas temperature reaches 190 DEG C, recyclegas outlet temperature
It increases, affects whole production technology.
In addition, making recyclegas outlet temperature wave since dry coke quenching recyclegas inlet temperature is fluctuated at 160 DEG C -190 DEG C
Move larger, recyclegas outlet temperature is normally at 130 DEG C.And the feed water preheater of the prior art is overall structure, heat-transfer surface
It is non-adjustable, so, when the fluctuation of recyclegas inlet temperature, such as:
Heat exchange equipment presses 180 DEG C of recyclegas inlet temperature, and recyclegas outlet temperature is 130 DEG C of parameter designing heat-transfer surfaces
When；
When 160-170 DEG C of recyclegas inlet temperature, recyclegas outlet temperature will drop to 120 DEG C hereinafter, by
Contain sulfide in recyclegas, 120 DEG C or so, for dew point corrosion critical point occurs, cause service life of equipment to decline.When
At 190 DEG C of recyclegas inlet temperature, recyclegas outlet temperature is 140 DEG C or more, it is difficult to meet the practical need of production technology
It wants.
Summary of the invention
The purpose of the utility model is to provide one kind can satisfy various technique requirements, improves the service life of radial heat pipe
Multistage it is adjustable using radial heat pipe as the feed water heater of heat-transfer surface.
The utility model is realized by following scheme:
A kind of dry coke quenching of the utility model multistage adjustable radial heat pipe-type feed water heater, including gas tank,
The recyclegas air inlet that gas tank lower part is set and the recyclegas exhaust outlet that gas tank top is set, feature
Be, the gas tank is composed of multi-stage heat exchanger unit, every grade of heat exchange unit by multiple groups with flange cabinet and
Heat-exchanging component composition on cabinet is set, and the heat-exchanging component includes water inlet header, water outlet header, inlet valve, water outlet
Valve sum number arranges radial heat exchanger tube, and the radial heat exchanger tube both ends are respectively communicated into water header and corresponding inlet valve
And water outlet header and corresponding flowing water Valve, every grade of heat exchange unit are connected by flange with bolt seal.
The radial heat exchanger tube is snakelike radial heat exchanger tube.
The utility model has the advantages that: since the utility model uses multistage radial heat pipe formula feed water heater,
In dry coke quenching recyclegas temperature fluctuation range, carry out control loop gas outlet temperature by adjusting the size of heat-transfer surface, thus
Reach and meet manufacturing technique requirent, and guarantees the purpose of the service life of equipment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the portion the A enlarged drawing of Fig. 1.
Specific embodiment
As depicted in figs. 1 and 2, the multistage adjustable radial heat pipe-type feed-water preheating dress of a kind of dry coke quenching of the utility model
It sets, including gas tank, the recyclegas air inlet 1 that gas tank lower part is set and the circulation that gas tank top is set
Gas exhaust port 2, which is characterized in that the gas tank is composed of multi-stage heat exchanger unit, and every grade of heat exchange unit is by more
Cabinet 6 of the group with flange includes water inlet header 7, goes out with the heat-exchanging component composition being arranged on cabinet 6, the heat-exchanging component
Water header 9, inlet valve 8,10 sum number of flowing water Valve arrange radial heat exchanger tube 11, and the radial heat exchanger tube 11 is that snakelike radial direction is changed
Heat pipe；11 both ends of radial heat exchanger tube are respectively communicated into water header 7 and corresponding inlet valve 8 and water outlet header
9 and corresponding flowing water Valve 10, the cabinet 6 with flange of every grade of heat exchange unit is connected by flange with bolt seal, this reality
The embodiment of setting three-level heat exchange unit combination is given with novel, shows the structural representation of level-one heat exchange unit 5 in Fig. 2
Figure, secondary heat exchange unit 4 and three-level heat exchange unit 3 are identical as the structure of level-one heat exchange unit 5, and how many grade are arranged in heat exchange unit
It to be determined according to the temperature of recyclegas and flow.
Using the utility model, in dry coke quenching recyclegas temperature fluctuation, can come by adjusting the size of heat-transfer surface
Control loop gas outlet temperature meets manufacturing technique requirent to reach, and extends the purpose of service life of equipment.
As embodiment, the utility model will be designed to three heat exchange units, i.e. level-one heat exchange unit 5, secondary heat exchange list
