Abstract

The utility model relates to a heat tube type inertial separator, which comprises a casing, an inner cavity, a partition board, an ash bunker and a heat tube which is provided with fins and arranged inside the separator inner cavity, wherein, a heating segment of the heat tube is plugged into the separator inner cavity; a heat tube cooling segment with water jackets is extended out of the separator; the water jacket is respectively connected with an upper water collection tube and a lower water collection tube, to effectively lower the temperature of high-temperature stacked gas, collect remaining heat of the stacked gas, and guarantee safety and effects in particle separation. The utility model more particularly adapts to working conditions of fluid bed industrial kilns.

Description

The heat pipe-type inertia separator

The utility model relates to separator, especially relates to a kind of heat pipe-type inertia separator.

Inertia separator at present commonly used comprises the U-shaped separator that relies on abrupt turn air flue separating particles, and adopt labyrinth type inertia separator of various baffle arrangements etc., the separator of these patterns only is adapted to fluidized-bed combustion boiler, and the separator of fluidized-bed gasification furnace all is in the hot operation situation, and do not have the fluidized-bed combustion boiler cooling water recirculation system, be not provided with superheater bank or convection bank in the boiler.This working condition is had relatively high expectations to the material of the resolution element of separator, as not adopting special heat transmission equipment, also very easily be out of shape even adopt expensive steel alloy to be in operation, cause separating effect to descend, influence the safe operation of equipment as resolution element.

The purpose of this utility model provides a kind ofly can bear high temperature, separative efficiency height, the heat pipe-type inertia separator of suitable fluidized-bed gasification furnace job requirement that can recovery waste heat.

Its objective is such realization:

It comprises housing, inner chamber, dividing plate, ash bucket and the resolution element that is arranged in the separator inner chamber, it is characterized in that resolution element is the integrated thermal tube bank, the bringing-up section of heat pipe is inserted in the separator inner chamber, the heat pipe cooling section of band water leg stretches out in the separator outside, and its water leg links to each other with upper and lower water header.

The heat pipe bringing-up section is provided with the fin of band overhead kick.

The heat pipe that advantage of the present utility model is to take to have very strong heat-transfer capability replaces general steel pipe, can reduce the temperature of high-temperature flue gas effectively, separate solid particles.The heat pipe bringing-up section absorbs the heat of high-temperature flue gas during separator work, is delivered to water leg through the heat pipe cooling section, can add the water among the hot water jacket, carries out the waste heat recovery of flue gas, can reduce the operating temperature of separator again, guarantees the safe operation of equipment.Owing to only be provided with collector pipe, only must set up comparatively simple circulation waterway simultaneously on inertia separator top, simple in structure, can satisfy fluidized-bed gasification furnace itself and not be with the cool cycles water route, and the very high operating mode of operating temperature needs.

Concrete structure of the present utility model is provided by drawings and Examples.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

By Fig. 1, Fig. 2 as seen, the utlity model has the housing 6 of a steel, inner for having refractory-lined inner chamber 2, inner chamber 2 bottoms link to each other with ash bucket 10 through dividing plate 9, heat pipe is the integrated thermal of being made up of bringing-up section 8 and cooling section 4, the heat pipe bringing-up section 8 that has the fin 7 of reverse hook type is inserted in the inner chamber 2, fixing by dividing plate 9 with top shell 6, the heat pipe cooling section 4 that has water leg 5 stretches out from the top of separator, water leg 5 and upper and lower water header 1,3 link to each other, and form a circulation waterway.
