Description
Technical field
This utility model relates to field of heat exchangers, particularly relates to a kind of desulfurization slurry heat exchanger.
Background technology
Coal-burning power plant is using coal as the energy, and coal combustion produces a large amount of SO in process of production2, for controlling SO2Realize SO2
Qualified discharge, coal-burning power plant's commonly used Gypsum Wet technology carries out flue gas desulfurization.
Wet desulfurization of flue gas by limestone-gypsum method technology uses cheap limestone as desulfurization absorbent, and limestone is through broken
Breakdown mill powdering and water mix and blend make absorption serosity；Then, in desulfurizing tower, absorb serosity and contact with flue gas adverse current, cigarette
SO in gas2With the CaCO in serosity3Reaction removing SO2, desulfurization product occurs anti-bottom desulfurizing tower with the oxidation air being passed through
Should, ultimately generate gypsum by-product；Flue gas after desulfurization sequentially passes through demister and removes droplet, after flue gas heat-exchange unit heat temperature raising
Through smoke stack emission.Wet desulfurization of flue gas by limestone-gypsum method technology has that response speed is fast, desulfuration efficiency is high, stable and reliable operation,
Side-product is easy to the advantages such as recycling, and coal-burning power plant is used widely the most at home.
The whole process of wet desulfurization of flue gas by limestone-gypsum method be a flue gas enthalpy be held essentially constant, in flue gas containing wet
Amount is continuously increased until wet flue gas is the process of saturation, and final desulfurizing tower exit gas temperature is down to adiabatic saturation temperature,
Slurry temperature is down to same temperature range the most accordingly.
In sweetening process, slurry temperature has considerable influence to desulfuration efficiency.Slurry temperature is the lowest, SO2With CaCO3At slurry
Dissolubility in liquid is the biggest, and overall mass transfer coefficient is the biggest, it is possible to be effectively improved desulfuration efficiency.But current Gypsum Wet
No matter flue gas desulfurization uses single cycle or Two-way Cycle form, its desulfurizing tower exit gas temperature all between 45 DEG C～55 DEG C,
Corresponding slurry temperature is also between 45 DEG C～55 DEG C.
Certain measure of all taking existing wet desulfurization of flue gas by limestone-gypsum method device reduces slurry temperature to carry further
High desulfurization efficiency.
By heat exchanger, desulfurization slurry heat exchange is lowered the temperature, and waste heat is derived utilization is a kind of effectively to drop desulfurization slurry
The mode of temperature, but owing to being mixed together with water through crushing grinding powdering by limestone during desulfurization slurry, impurity particle
More, the sheet structure of usual heat exchanger, rely on contact to contact with each other between plate, under the effect with contact of the plate ripple,
Medium runner is complicated three-dimensional netted stream, being continually changing of flow field, being continually changing of flowing to, the catalytic action of contact in addition,
Between plate, the field of flow in runner can produce bigger inhomogeneities, at the relatively low stagnant area of flow velocity and contact region, it is easy to occurs
The blocking of particulate matter and dirty, it is impossible to realize the permanently effective cooling to desulfurization slurry.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, it is provided that a kind of to desulfurization
Serosity effective temperature-reducing and the desulfurization slurry heat exchanger being not easily blocked.
This utility model is to be achieved by the following technical programs:
A kind of desulfurization slurry heat exchanger, including housing, is located at housing central section heat exchanger plates bundle, and described housing both sides are provided with serosity
Drain case, described heat exchanger plates bundle includes that multiple plates, described plate include main heat-transfer area, are uniformly distributed in the flow-disturbing of main heat-transfer area
Ripple and pressure-bearing ripple, described plate groups poststack forms medium flow channel and slurry flow channel in plate both sides, described
In slurry flow channel, described flow-disturbing ripple is less than the 1/2 of serosity runner spacing with the height of pressure-bearing ripple, is formed without contact.
Described medium flow channel one or both sides connect medium collecting pipe, and the quantity of every side medium collecting pipe is one
Two or four.
The beneficial effects of the utility model are:
The slurry heat exchanger serosity flowing runner that this utility model relates to is board-like straight-through runner, is improving heat transfer efficiency
Effectively prevent serosity from blocking in heat exchanger, it is simple to be applied in desulphurization plant simultaneously, serosity heat exchange is lowered the temperature, improve de-
Sulphur efficiency, the waste heat of desulfurization slurry can be recycled, the serosity of cooling and flue gas effect, owing to its temperature reduces, heat transfer
Mass transfer effect strengthens, and desulfurized effect is greatly improved.

Eliminate the impact of contact, thus from injection point to outlet, field of flow keeps consistent substantially, eliminate particulate matter blocking and amass
The precondition of dirt, the most just can solve particulate matter blocking and fouling problem up hill and dale.
In preferred embodiment of the present utility model, medium flow channel one or both sides connect medium collecting pipe 8, and every side
The quantity of medium collecting pipe is a two or four, and the structure of its internal plate the most effectively adjusts, to adapt to make simultaneously
With needs.
The slurry heat exchanger serosity flowing runner that this utility model relates to is straight-through runner, effectively prevents serosity at heat exchanger
Interior block, it is simple to be applied in desulphurization plant, serosity heat exchange is lowered the temperature, waste heat is derived and can be recycled, cold
But serosity and flue gas effect, owing to its temperature is relatively low, heat and mass effect strengthens, and desulfurized effect is greatly improved.
