Description

Double-stage cyclone

Technical Field

The utility model relates to the field of combustors, in particular to a double-stage cyclone.

Background

At present, combustion is carried out on a clean fuel burner which is used for incineration treatment of waste gas liquid in China; the waste liquid and the waste gas are sprayed into the incinerator for treatment through other channels.

The combustion effect of the burner is directly determined by the combustion air mixing condition of the multifunctional burner; most multifunctional burners adopt direct current or single rotational flow structures, so that the combustion effect is poor; eventually resulting in lower combustion efficiency; low burning removal rate and the like; meanwhile, the conditions of short service life of the incinerator refractory material and the like caused by uneven temperature of the incinerator hearth can be caused.

Disclosure of Invention

The utility model aims to provide a double-stage cyclone.

The utility model has the innovation point that the two-stage cyclone ensures that the temperature of the flame sprayed out forms uniform temperature in the hearth, and the service life of the refractory material is prolonged.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

the utility model provides a doublestage swirler, including the interior barrel of vertical arrangement, middle barrel, the urceolus body, interior barrel, middle barrel, the coaxial arrangement of urceolus body, be equipped with a plurality of one-level whirl boards between interior barrel and the middle barrel, be formed with a wind channel between interior barrel and the middle barrel, be equipped with a plurality of second grade whirl boards between middle barrel and the urceolus body, be formed with the secondary wind way between middle barrel and the urceolus body, a serial communication port, one-level whirl board equals with second grade whirl board quantity, on the horizontal cross-section, the normal of one-level whirl board on the inner barrel and its tie point, the extending direction contained angle with one-level whirl board is a, the normal of the second grade whirl board on the middle barrel and the extending direction contained angle b of second grade whirl board, a is 95, b is 3 ~5 than a, one-level whirl board is c with vertical plane contained angle, c is 45, second grade whirl board is d with vertical plane contained angle, d is 40.

Preferably, the included angle between the connection point of the second-stage swirl plate and the middle cylinder and the connection point of the first-stage swirl plate and the inner cylinder is e, and the included angle between e and the connection point of the first-stage swirl plate and the inner cylinder is 22-25 degrees. The high-temperature flue gas of the hearth is more easily sucked into the flame through the secondary cyclone plate, so that the stability of the flame is improved, and the low-nitrogen combustion is realized through low-oxygen combustion.

Preferably, the primary swirl plate is a straight blade, and the secondary swirl plate is a streamline blade. The stage swirl plate adopts a streamline curve with equal-angle speed for streamline blades, so that the flow abrasion of the second stage swirl plate is reduced.

The beneficial effects of the utility model are as follows:

1. the two-stage cyclone in the utility model enables the temperature of the flame sprayed out to form uniform temperature in the hearth, thereby prolonging the service life of the refractory material.

2. According to the utility model, the high-temperature flue gas of the hearth is more easily sucked into the flame through the secondary cyclone plate, so that the stability of the flame is improved, and the low-nitrogen combustion is realized through low-oxygen combustion.
