Abstract

The utility model relates to a dust removal device for a chimney, and the utility model belongs to the technical field of removing dust from smoke gas of a boiler and a stove; the utility model solves problems that the existing small boiler and the existing hot water stove are not provided with dust removal devices. The utility model adopts the structure that a smoke cap is sheathed on the outside of a flue, and a dust removal outer housing is sheathed on the outside of the smoke cap; under the utilization of the principle of changing the flow speed of hot gas in the flue, heavy granules in the smoke gas are removed, (for example, flour-shaped dust is evidently appreciable removed), and thus, the discharged smoke gas is purified.

Description

The chimney deduster

The utility model belongs to the flue gas ash removal technical field of stove, kitchen range flue.

According to the knowledge of the applicant, present general miniature boiler and water heater, as long as its combustion efficiency is good, the flue gas of emerging from chimney looks like clean, but in fact contained ash content fume amount also has much, also causes some pollutions to environment.Wherein great majority are not installed deduster, directly discharging: the installation deduster, high because of its price, Maintenance and Repair are difficult for, and bring many burdens to the user.Along with the enhancing of environmental consciousness, the dust removal problem of miniature boiler and water heater certainly will will place on the agenda.

The purpose of this utility model is exactly in the flue of this type of boiler easy deduster to be installed, and it has certain dust removing effects, and itself is with low cost, and convenience easy to repair does not add power in addition, easily for the user accepts, is fit to promote the use of.

The utility model is like this design, a kind of chimney deduster, and the flue of tubular, its underpart has adpting flange to be connected with boiler chimney, and the cigarette cap that shape such as cylinder have the end is being supported by several strong points in its top; There is the deduster shell outside of flue, cigarette cap; The deduster shell upper is the exhanst gas outlet of discharging flue gas, and there are dust storage chamber and ash hole in its underpart.

The sectional area of the inner exhaust gases passes of tubular flue is equal to the sectional area of exhaust gases passes between cigarette cap and the flue, and the two is all less than the sectional area of exhaust gases passes between deduster shell and the cigarette cap.

Discharge hot flue gas when boiler and water heater, continue to rise after entering flue, stop through the cigarette cap, change downward shunting into, upset is discharged through exhanst gas outlet up then, in this process, its flow velocity is when turning back rising from the cigarette cap, because the exhaust gases passes sectional area increases, thermal current speed obviously slows down, it is fast promptly to be folded to dirty velocity of flue gas from the cigarette cap, air velocity when counter-rotating is risen again is slow, holds the heavy particle flue dust of wrapping up in the air-flow under the arm and is just got rid of to dust storage chamber, and hot gas is separated with heavy particle flue dust.Isolated flue dust is regularly discharged through ash hole.

This kind deduster simple structure, with low cost, install easily, easy to maintenance.Install and use on several miniature boilers and water heater, the flue dust of collection is a cinerous, and thin dust removing effects is very obvious as flour, and dust removal efficiency reaches more than 70%.

The contrast accompanying drawing is further described below.

Fig. 1 is an aufbauprinciple schematic diagram of the present utility model.

Among the figure: 1. exhanst gas outlet 2. cigarette caps 3. deduster shells 4. flues 5. support 6. dust storage chambers, 7. ash holes, 8. adpting flanges

As can be seen from Figure 1, adpting flange 8 is arranged at the bottom of flue 4, and top supports 5 by several, is supporting cigarette cap 2, and there is deduster shell 3 outside, and its top is exhanst gas outlet 1, and there are dust storage chamber 6 and ash hole 7 in its underpart.

Adpting flange 8 is mounted in the smoke outlet of boiler, and the flue gas of heat enters thus, rises through flue 4, descends after cigarette cap 2 stops, behind the smoke cap 2, transfers again to rise, and by exhanst gas outlet 1, row is to atmosphere.In this process, airflow direction and speed also change.Flue gas flings downwards after being stopped by cigarette cap 2, when transferring to rise, because this moment, the sectional area of exhaust gases passes became big, air velocity diminishes, and the heavy particle that air-flow is swept along is a flue dust, because the gravity effect just falls into dust storage chamber 6, in this process, reach the purpose of dirt, gas separation.Be deposited in the flue dust of 6 li of dust storage chambers, can discharge through ash hole 7.

Claims (2)

1, a kind of chimney deduster, the flue that it is characterized in that tubular, its underpart has adpting flange to be connected with boiler chimney, the cigarette cap that cylinder has the end is being supported by several strong points in its top, there is the deduster shell outside of flue, cigarette cap, the deduster shell upper is the exhanst gas outlet of discharging flue gas, and there are dust storage chamber and ash hole in its underpart.

2, chimney deduster according to claim 1 is characterized in that the sectional area of the exhaust gases passes of tubular flue inside is equal to the sectional area of exhaust gases passes between cigarette cap, the flue, and the two is all less than the sectional area of exhaust gases passes between deduster shell and the cigarette cap.
