Description
Technical field
The utility model belongs to flue gas desulfurization and administers field, and in particular to a kind of heat exchanger of desulfurizer, more particularly to
A kind of detachable enamelled heat exchanger designed specifically for flue gas desulfurization device.
Background technique
Flue gas desulfurization device is to reduce SO2, NOx emission main means and technique, denitration at present mainly has wet process, dry
The techniques such as method, active carbon, the flue gas into desulfurizer need to generally cool down, conventional at present to use waste heat boiler or GGH pairs
Flue gas is cooled down.
But it fluctuates larger, flue gas exit temperature there are boiler export flue-gas temperature using the technical solution of waste heat boiler to adjust
Difficult deficiency, and heat boiler outlet temperature is generally higher, has larger impact to the normal operation of desulfurizing tower.Due in flue gas
SO2, the big temperature of NOx content it is high, and conventional simple steel heat exchanger not acid corrosion-resistant, high grade stainless steel or titanium matter heat exchanger valence again
Lattice are high, and heat exchanger tube is welding connecting mode, replaces difficulty after heat exchanger tube corrosion, is particularly at the heat exchange in middle position
Heat exchanger integral replacing can only be brought larger impact to the normal, stable of desulfurizer, economical operation after pipe corrosion.And
Heat exchanger tube can not observe corrosion condition inside heat exchanger, once heat exchanger tube corrosion failure, flue gas enter cooling through breakage
Medium causes damages to cooling system.

Equipped with inlet of cold air, right part is equipped with hot air outlet, is respectively provided with one piece of support tube sheet in heat exchanger body left and right end portions, supports
Tube sheet completely encloses heat exchanger body left and right end portions, the corresponding several through-holes in position is equipped on two pieces of support tube sheets, two
It is inserted with heat transfer element between the through-hole of block support tube sheet, using soft seal set connection between heat transfer element and tube sheet.
Further the heat transfer element is ordinary carbon steel straight tube or the ordinary carbon steel straight tube with fin, and in outer tube layer
Sintering has enamel layer, forms enamel straight tube or the enamel straight tube with fin；The surface of flue gas is contacted all in heat exchanger body
Sintering has enamel layer.Corrosion resistance compared to ordinary carbon steel heat exchanger tube enamel heat exchanger tube greatly enhances, and compares high grade stainless steel
Or the economy of titanium matter heat exchange tube enamel heat exchanger tube is particularly evident.
Further the enamel straight tube is matched with the outer diameter of through-hole connecting portion with through-hole diameter, other portions of enamel straight tube
The outer diameter of position is less than the outer diameter of enamel straight tube and through-hole connecting portion.When installation is with replacement heat exchanger tube, intermediate and both ends end
Outer diameter it is smaller, be easy to reduce with the probability of through-hole collision, protect enamel layer not because external force falls off by through-hole.
Further the enamel straight tube with fin is matched with the outer diameter of through-hole connecting portion with through-hole diameter, fin
Outer diameter be less than enamel straight tube and through-hole connecting portion outer diameter.The circulation area of enamel straight tube its cooling medium with fin
It is smaller, but heat transfer area increases several times than straight tube, and for convenience of installing and protecting enamel layer, monnolithic case is similar with straight tube.
Further the soft seal set is the shapes such as circular ring type or square, rectangle, and soft seal set uses high temperature resistant bullet
Property material.The stage is being installed or is replacing, heat exchanger is in cold conditions, and it is logical that the size of soft seal set can just allow heat exchanger tube to pass through
Hole, temperature increases in heat exchanger after operation, and soft seal covers expanded by heating, and the gap between heat exchanger tube and through-hole is blocked simultaneously jail completely
Jail is fixed in through-holes by heat exchanger tube.
Further the hot fume import or hot fume outlet are flexibly connected with heat exchanger body.In order to install and examine
It repairs conveniently.
Further the branch heat exchanger body and stay tube plate junction are equipped with sliding slot, are equipped with idler wheel, sliding slot side in sliding slot
Edge is equipped with sealing joint strip, and stay tube plate can slide back and forth in sliding slot.Smoke inlet or the outlet of side are opened when installation or maintenance,
The support tube sheet of heat exchanger tube will be put on, is pushed into or pulls out heat exchanger body along the chute.
SO is further equipped at the hot air outlet2Detection device, SO2Detection device connects warning device.Once hair
Raw heat exchanger tube corrosion failure, flue gas enter cooling medium, SO2Detection device detects smoke components, and warning device is with sound, lamp
The modes such as light, closing flue gas, closing cooling medium are alarmed.
The utility model has the advantages that compared with the prior art, the advantages of the utility model are: exchanging heat in terms of existing technologies
The shape of sealing structure and heat exchanger tube between pipe and support tube sheet is adjusted and has been optimized, and can be facilitated and be carried out tearing open for heat exchanger tube
Dress, replacement support and are flexibly connected convenient machine core integral installation replacement between tube sheet and heat exchanger, be damaged by removable parts
Heat exchanger tube can satisfy the needs of actual production to extend the whole service life of heat exchanger；Increase furthermore detection device and
The breakage of Shi Faxian heat exchanger tube；In addition, the utility model is not only cooled down flue gas in desulfurizer, moreover it is possible to produce
Raw a certain amount of hot-air is provided convenience with supplying user in need for the comprehensive utilization of thermal energy, has certain economy
Benefit and social benefit.
