Abstract
An air-heating type gasifier heat exchanger tube syndeton, comprises connector and heat exchanger tube; Described connector is the rectangular configuration of hollow, and four angles of rectangle are respectively arranged with four bayonet sockets, and described bayonet socket is provided with corner angle and the groove of rectangular shape; Described heat exchanger tube is provided with connection fin, and described connection fin is provided with the projection of rectangular shape; Described projection and groove cooperatively interact, and are provided with several hydraulic pressure fixing points on corner angle.The utility model has overcome conventional air-heating type gasifier connector and cannot meet actual use and cannot cause the shortcomings such as leakage by effective compensation, makes that large-scale gasifier equipment is long-time uses more reliable, stable, safety.
Description
Technical field
The utility model relates to a kind of air-heating type gasifier, specifically a kind of air-heating type gasifier heat exchanger tube syndeton.
Background technology
Air-heating type gasifier is to utilize air to carry out heat exchange, and cryogenic liquid is changed into gas at normal temperature, to meet the application in each fields such as electronics, chemical industry, iron and steel, cutting, natural gas.The air-heating type gasifier generally adopting is in the market less demanding to connector, generally be straight-plate-type brace, two ends adopt argon arc welding welding, therefore heat exchanger tube produces in the meeting of expanding with heat and contract with cold that is frequently used alternatingly middle generation " whip " sound stretching, of long duration place of can drawing crack two ends welding with fin, cause integral device strength decreased, also in the time of can making bridge piece shrink, cause that huge stress causes dielectric leakage, even by wind, fallen, cause major accident, also can cause larger maintenance cost; So particularly the mega project on seashore, riverside or limit, hillside adopts traditional straight-plate-type brace connect abnormally dangerous and cannot use.
Utility model content
The purpose of this utility model is to provide a kind of air-heating type gasifier heat exchanger tube syndeton that can compensationly flexibly connect.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is:
An air-heating type gasifier heat exchanger tube syndeton, comprises connector and heat exchanger tube; Described connector is the rectangular configuration of hollow, and four angles of rectangle are respectively arranged with four bayonet sockets, and described bayonet socket is provided with corner angle and the groove of rectangular shape; Described heat exchanger tube is provided with connection fin, and described connection fin is provided with the projection of rectangular shape; Described protruding external diameter is more smaller than groove internal diameter, and projection cooperatively interacts with groove, and gap between the two can meet the deformation requirements that heat exchanger tube fin expands with heat and contract with cold and causes, is provided with several hydraulic pressure fixing points on corner angle.
Preferably, the quantity of described hydraulic pressure fixing point is two or three.
Further, the width of described connector is 120-150mm.
Further, the thickness of described connector is 4mm.
Further, described heat exchanger tube also comprises the common fin without projection.
The utility model is that deformable insertion slot type flexibly connects, make to have obtained between heat exchanger tube fin and adjacent fins effective flexible compensation, can not produce " whip " sound, can drawing crack connector and fin hydraulic pressure fixing point yet, thus the dielectric leakage that huge stress causes while avoiding bridge piece to shrink, caused.

Fig. 2 is the cutaway view of heat exchanger tube;
Fig. 3 is the partial enlarged drawing of connecting portion after heat exchanger tube fin is connected with connector;
Wherein: 1, connector, 11, bayonet socket, 111, corner angle, 112, groove, 2, heat exchanger tube, 21, connect fin, 211, projection, 22, common fin.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in detail:
As Figure 1-3, heat exchanger tube 2 rectangular array, each heat exchanger tube 2 is provided with four and connects fin 21, connects fin 21 ends and is provided with rectangular preiection 211.The rectangular configuration that connector 1 is hollow, is respectively equipped with four bayonet sockets 11 on four angles of rectangle, and described bayonet socket 11 is provided with corner angle 111 and the groove 112 of rectangular shape, and described protruding 211 external diameters are more smaller than groove 112 internal diameters, and projection 211 cooperatively interacts with groove 112.Connector 1 is arranged in the middle of four heat exchanger tubes 2, described bayonet socket 11 is respectively with to be connected accordingly fin 21 on four heat exchanger tubes 2 around in mating connection by projection 211 and groove 112, gap between projection 211 and groove 112 can meet the deformation requirements that heat exchanger tube fin 21 expands with heat and contract with cold and causes, three hydraulic pressure fixing points are set on corner angle 111.
On heat exchanger tube 2, except four connection fins 21 of foregoing description, can also be provided with several common heat exchange fins 22; The length of connector 1 and thickness can arrange according to actual needs, and in general width 120-150mm, thickness 4mm are comparatively suitable.
The utility model has overcome conventional air-heating type gasifier connector and cannot meet actual use, cannot cause the shortcomings such as leakage by effective compensation.
