Description

A kind of corrosion resistant enamel finned tube exchanger
Technical field
The utility model belongs to field of heat exchangers, is specifically related to a kind of heat exchanger being applicable to the industry residual neat recovering systems such as chemical industry, electric power, iron and steel and medicine.
Background technology
Today that, energy day increasingly serious in environment situation is becoming tight, energy-saving and emission-reduction have become an important and pressing task of current Chinese economy social development.In the industries such as chemical industry, electric power, iron and steel and medicine, a large amount of low temperature exhaust heats is had to recycle, cause the reason that cannot recycle to be, contain sulfur dioxide in the process gas of discharge or flue gas, sulfur dioxide is oxidized further and generates sulfur trioxide (2SO under the effect of catalyst 2+ O 2=2SO 3), SO 3sulfuric acid vapor (SO is generated with the water vapour in flue gas 3+ H 2o=H 2sO 4), the existence of sulfuric acid vapor makes the dew point of flue gas significantly improve.Because the temperature of heat exchanger heating surface is lower, wall temperature is often lower than flue gas dew point, and such sulfuric acid vapor will condense on the heating surface of heat exchanger, causes the cold end corrosion of equipment heating surface.
Way traditional is at present the temperature that process gas or flue-gas temperature are down to required for technique by the modes such as employing spraying cooling, or is discharged in an atmosphere at this point, causes a large amount of energy wastes, the consumption of recirculated water, and contaminated environment.
Utility model content
It is large that the purpose of this utility model is to provide a kind of heat transfer area, and heat-transfer effect is good, can avoid low-temperature dew point corrosion problem, effectively reclaims the heat exchanger of low-temperature level waste heat.
The technical solution adopted in the utility model is: a kind of corrosion resistant enamel finned tube exchanger, comprises casing and heat exchanger tube; Casing is provided with inlet, outlet; Multiple heat exchanger tube is parallel to each other and is fixed in casing, is in turn connected into a heat exchanger tube array by elbow; Heat exchanger tube array is one or more, distributes side by side when two or more; The two ends of heat exchanger tube array are connected with the medium header to be heated be arranged on outside casing and heated medium header respectively.
Heat exchanger tube is fin-type heat exchanger tube, and the surface of heat exchanger tube is provided with enamel cover layer;
Elbow is arranged on inside or the outside of casing;
Casing can be designed to square or circular.
Process gas or flue gas enter from casing air inlet perpendicular to heat exchanger tube, discharge after flowing through heat exchanger tube from gas outlet casing, and heated medium (water or other liquid) enters heat exchanger tube array from medium header shunting to be heated, confluxes into heated medium header after being heated; Can be used in the recovery system of low temperature exhaust heat.Heat exchanger tube is fin-type heat exchanger tube, and heat transfer area is large, and heat-transfer effect is good, the enamel cover layer on surface completely cuts off industrial gasses or flue gas, avoid process gas or flue gas directly to contact with fin-type heat exchanger tube, have well corrosion-resistant, thus ensure the service life of product.
The invention has the beneficial effects as follows:
1, heat exchanger tube adopts fin-type heat exchanger tube, effectively adds heat transfer area and heat-transfer effect, greatly reducing volume and the weight of equipment.
2, the enamel cover layer on fin-type heat exchanger tube heating surface, by process gas or flue gas and heating surface metallic shield, avoid process gas or flue gas directly contacts with heating surface metal, thoroughly solve low-temperature dew point corrosion problem, ensure the normal operation of heat exchanger, realize the recovery of low-temperature heat energy.
3, enamel cover surface is smooth, effectively can reduce flue gas resistance, greatly reduce fouling of heating surface, improves heat transfer effect.

Detailed description of the invention
Below in conjunction with accompanying drawing, structure of the present utility model is further described, refers to shown in Fig. 1:
A kind of corrosion resistant enamel finned tube exchanger, comprises casing 1 and heat exchanger tube 3; Casing 1 is provided with inlet, outlet; Heat exchanger tube 3 preferentially adopts fin-type heat exchanger tube, and multiple fin-type heat exchanger tube is parallel to each other and is fixed in casing 1, is in turn connected into a fin-type heat exchanger tube array by elbow 2; Fin-type heat exchanger tube array is one or more, is distributed in casing 1 when two or more side by side; The two ends of fin-type heat exchanger tube array are connected with the medium header 10 to be heated be arranged on outside casing 1 and heated medium header 11 respectively;
The surface of above-mentioned fin-type heat exchanger tube is provided with enamel cover layer, and isolated process gas or flue gas, avoid process gas or flue gas directly to contact with fin-type heat exchanger tube, have well corrosion-resistant, thus ensure the service life of product.
Casing 1 is frame structure, ensures the stability of whole device structure.Be made up of steel plate, according to the pressure of industrial gasses or flue gas, casing 1 can be designed to square or circular.
Medium header 10 to be heated and heated medium header 11 are made up of steel pipe, and body is provided with the through hole matched with fin-type heat exchanger tube 3, fin-type heat exchanger tube 3 connects.
Described elbow 2 is formed by steel tube bending, and for the connection between each fin-type heat exchanger tube 3, elbow 2 can be arranged in inside casing 1 or outside.
Process gas or flue gas enter from casing air inlet perpendicular to fin-type heat exchanger tube, discharge from gas outlet casing after flowing through fin-type heat exchanger tube, heated medium (water or other liquid) enters fin-type heat exchanger tube array from medium header shunting to be heated, confluxes into heated medium header after being heated; This product thoroughly solves heat exchanger low-temperature dew point corrosion problem, and effective recovery low-temperature level waste heat, ensure that normal operation and the heat transfer effect of heat exchanger.
