Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with drawings and Examples of the present utility model, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.

Embodiment 1

Shown in Fig. 2 to Fig. 5 and Fig. 7, the combustion-supporting of this utility model one embodiment, including drawing flame body 1 and connecting portion 2, draw flame body 1 and there is cancave cambered surface 11 and at least one through hole 12, the flame 6 that incinerator nozzle 4 sprays can be caused cancave cambered surface 11 by through hole 12; Connecting portion 2 is arranged on the end drawing flame body 1, and the charging from incinerator feed pipe 5 can be caused cancave cambered surface 11 by connecting portion 2.

Combustion-supporting of the present utility model can be located at incinerator, particularly injection type incinerator, combustion-supporting draws the through hole 12 of flame body 1 can cause cancave cambered surface 11 by the flame 6 that incinerator nozzle 4 sprays, it is simultaneously connected with portion 2 and the charging from incinerator feed pipe 5 can be caused cancave cambered surface 11, when burning, waste liquid, the chargings such as waste gas are after connecting portion 2, under the guiding of the negative pressure being centrally formed at cancave cambered surface 11, it is allocated drawing flame body 1 place, flame 6 is entered the cancave cambered surface 11 drawing flame body 1 by the through hole 12 drawn on flame body 1, the charging having been enter into cancave cambered surface 11 is carried out mixed combustion, the setting drawing flame body 1 increases the burning area of charging, improve the quality of mixed combustion, charging is made fully to burn in mixing section 31, it is achieved thereby that burning and not over-emitting black exhaust completely.

The concrete structure drawing flame body 1 is not done strict restriction by this utility model, as long as it has cancave cambered surface 11 and corresponding through hole 12. Consider from preparation, cost etc. are many-sided, draw the arc that flame body 1 can be arc, particularly consistency of thickness, it is to be understood that this arc has cancave cambered surface 11 and the convex globoidal 13 (as shown in Figure 4) corresponding with cancave cambered surface 11. Can be readily available this by the conventional method of prior art and draw flame body 1, for instance, it is possible to carry out cutting can obtain by selecting suitable sheet material suitably to bend or choosing suitable tubing.

Additionally, radian and the arc etc. that draw the cambered surface (cancave cambered surface 11 and convex globoidal 13) of flame body 1 all can be determined according to actual needs. In general, the cancave cambered surface 11 and the convex globoidal 13 that draw flame body 1 are cylinder, for instance can be the cylinder of the comparatively rule such as the face of cylinder, elliptic cylinder, hyperbola cylinder and parabola shaped cylinder, it is also possible to for other irregular cylinders.

In the present embodiment, the cross sectional shape of above-mentioned arc can be circular arc; Further, the central angle of circular arc equals to or less than 180 degree. When the central angle of circular arc is less than 180 degree, the opening of cambered surface is enlarging shape, and which is conducive to distribution and the diffusion of charging; And when the central angle of circular arc is equal to 180 degree, cancave cambered surface 11 and convex globoidal 13 are semi-cylindrical arc, which is easy to processing. Existing conventional cylinder arc sheet material is used equally to prepare and above-mentioned draws flame body 1.

This utility model to through hole 12 number is set and set-up mode does not do strict restriction, as long as being beneficial to the distribution of flame 6 and can guarantee that the bulk strength drawing flame body 1; Particularly, when inlet amount is bigger, can suitably increase the length drawing flame body 1, and enough through holes 12 are set so that substantial amounts of waste gas, waste liquid charging can distributed uniform, with reach increase burning area purpose. In one embodiment, arc is along the circumferential direction symmetrically arranged with the first through hole 121 and the second through hole 122, i.e. the first through hole 121 and the second through hole 122 are horizontally arranged on the circumferencial direction of arc (as shown in Figure 4).

In the present embodiment, the cross sectional shape of arc is semicircle, and the first through hole 121 and the second through hole 122 are and are horizontally disposed with; Further, the first through hole 121 and the second through hole 122 are arranged at 45 degree of angles place, i.e. the first through hole 121 is positioned at arc center upper portion position, and the second through hole 122 is positioned at arc lower central position. Additionally, the first through hole 121 and the second through hole 122 all can longitudinal arrangement multiple, for instance four (as shown in Figure 3), now arc has 8 through holes 12.

In another embodiment, ensureing on the basis of arc bulk strength, it is also possible to the central authorities at arc arrange intermediate throughholes 123, and intermediate throughholes 123 is between the first through hole 121 and the second through hole 122 (as shown in Figure 5). Intermediate throughholes 123 is set and advantageously ensures that being uniformly distributed of flame 6, so that charge combustion is more abundant.

The concrete structure of connecting portion 2 is not done strict restriction by this utility model, as long as it has through hole thus the charging from incinerator feed pipe 5 is caused cancave cambered surface 11. Comparatively routinely, connecting portion 2 can be connecting tube. The internal diameter of this connecting tube all can be identical with feed pipe 5 with external diameter. Further, the length of connecting portion 2 is it suffices that the charging that feed pipe 5 can export 51 causes flame 6 place.

In the present embodiment, connecting portion 2 is connecting tube, draws the arc that flame body 1 is semicircle for cross sectional shape, and connecting tube is all identical with the external diameter of arc and internal diameter, and connecting tube and arc one-body molded (as shown in Figure 2). In this approach, the material of connecting portion 2 and arc is exotic material, and the combustion-supporting being now made of one piece will not produce, because material is different, the problem of coming off in actual use, and which is easy to processing.

Embodiment 2

The combustion-supporting of another embodiment of this utility model, roughly the same with the combustion-supporting of embodiment 1. Maximum of which difference is in that, the first through hole 121 and all outward-dipping setting of the second through hole 122, i.e. the first through hole 121 is arranged towards arc upper end, and the second through hole 122 arranges (as shown in Figure 6) towards arc lower end. In this approach, the first through hole 121 and the second through hole 122 are formed horn-like, are conducive to expanding burning area, thus ensureing fully burning.

The tilt angle alpha 1 of above-mentioned first through hole 121 and the tilt angle alpha 2 of the second through hole 122 are not done strict restriction by this utility model, all are conducive to the clean-burning angle of charging all suitable in this utility model.

Additionally, in the present embodiment, connecting portion 2 and drawing between flame body 1 for welding fabrication; Further, first through hole the 121, second through hole 122 and the equal longitudinal arrangement of intermediate throughholes 123 three.
