Abstract

The utility model discloses an energy-saving combustion chamber for ovens, which comprises a heat preservation box body (1) and a heat exchanger (2), wherein one side of the heat preservation box body (1) is provided with a blower (8); the other side of the heat preservation box body (1) is provided with a pipeline (3) used for connecting an oven. The utility model is characterized in that the upper part of the heat preservation box body (1) is provided with a smoke collection cavity (4); the upper part of the smoke collection cavity (4) is provided with a smoke discharging tube (5) and a filtration chamber (10); a filter (6) is arranged in the filtration chamber (10) which is connected with the blower (8) through a pipeline (7); valve plates (9) are arranged on the smoke discharging pipe (5) and the filter (6). The utility model can make waste gases generated by a combustion chamber collected. The waste gases are used as part of air sources for the combustion chamber through filtration. Thus, the utility model fully utilizes heat quantity generated by fuel combustion, can improve the heat efficiency of the combustion chamber and save fuel more than 25% by tests. The utility model has the characteristics of simple structure, high heat efficiency and low use cost, and can be used as a heating device for ovens.

Description

The energy-saving combustion chamber that baking oven is used

Technical field

The utility model relates to the combustion chamber that a kind of combustion chamber, particularly baking oven are used.

Background technology

The fuel oil or the gas combustion chamber of spraying baking oven (comprising drying tunnel) usefulness mainly are that the heating to various article in the baking oven provides thermal source.Existing baking oven generally connects the combustion chamber by pipeline, and blower fan is installed on the next door, combustion chamber, by the air in the heat exchanger in fuel oil or the gas burner system heating flame chamber, by blower fan the hot-air of heat exchanger outside is blown in the baking oven more then.Waste gas after burning is then directly discharged by smoke exhaust pipe.The shortcoming that such combustion chamber exists is that the thermal efficiency is not high, the waste incendiary material.Also some scheme when baking oven designs with baking oven in used hot-air be recovered in the blower fan and reuse, but energy-saving effect is still not ideal enough.

Summary of the invention

The purpose of this utility model is, the energy-saving combustion chamber that provides a kind of baking oven to use.The thermal efficiency of fuel can be improved in this combustion chamber, reduces the consumption of incendiary material.

The utility model is to constitute like this.The energy-saving combustion chamber that baking oven is used, it comprises insulation casing 1, heat exchanger 2, and a side of insulation casing 1 is provided with blower fan 8, and opposite side is provided with the pipeline 3 that is used to connect baking oven; It is characterized in that: above insulation casing 1 smoke collecting chamber body 4 is housed, smoke exhaust pipe 5 and filter chamber 10 are equipped with in smoke collecting chamber body 4 tops; Filter 6 is housed in the filter chamber 10, and filter chamber 10 connects blower fan 8 through pipeline 7; Smoke exhaust pipe 5 and filter 6 are provided with valve plate 9.

The energy-saving combustion chamber that above-mentioned baking oven is used preferably is coated with adiabator layer 11 in the outside of smoke collecting chamber body 4 and filter chamber 10.

Compared with the prior art, the utility model gets up the gas sampling that the combustion chamber produces, and later on as the part air source of combustion chamber, has made full use of the heat that fuel combustion produces through filtration, has improved the thermal efficiency of combustion chamber.Through actual measurement, the utility model fuel savings can reach more than 25%.Have simple in structure, easy to implement, thermal efficiency height, the characteristics that use cost is low.Can be used as the heater that baking oven particularly sprays baking oven uses.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the structural representation of the utility model netted filtering tube.

The specific embodiment

Embodiment of the present utility model.The energy-saving combustion chamber that baking oven is used can be transformed on existing combustion chamber, adopts existing insulation casing 1 and heat exchanger 2, connects blower fan 8 in insulation casing 1 one sides, and opposite side is installed the pipeline 3 that is used to connect baking oven.Above insulation casing 1, a smoke collecting chamber body 4 is installed, smoke exhaust pipe 5 and filter chamber 10 are installed above smoke collecting chamber body 4; Filter 6 is installed in the filter chamber 10, and this routine middle filtrator 6 is netted filtering tubes, and the netted filtering tube is constructed as shown in Figure 2.Filter chamber 10 is connected to blower fan 8 by pipeline 7.On smoke exhaust pipe 5 and filter 6, be provided with valve plate 9.In order to improve the UTILIZATION OF VESIDUAL HEAT IN effect, can coat an adiabator layer 11 in the outside of smoke collecting chamber body 4 and filter chamber 10.Smoke collecting chamber body 4, filter chamber 10 and smoke exhaust pipe 5 are coated in the insulation casing 11.

Waste gas in the combustion chamber after the fuel combustion is collected by smoke collecting chamber body 4 earlier after exhaust opening is discharged, and delivers to blower fan 8 after filtering through filter 6 again, is sent in the heat exchanger 2 by blower fan 8, has improved the service efficiency of heat energy.In smoke exhaust pipe 5 and filter 6, be respectively equipped with valve plate 9, can make smoke exhaust pipe 5 and filter 6 simultaneously a job can only be arranged.For prevent the combustion chamber work once in a while undesired, the excessive effect that influences baking oven of combustion product gases impurity that produces, when the impurity that detects combustion product gases is excessive, can close filter 6 valve plate, open the valve plate of smoke exhaust pipe 5 simultaneously, gas fume after burning is directly discharged.

As a kind of distortion of the present utility model, also can smoke exhaust pipe 5 be installed directly in filter chamber 10, at the mouth of pipe of smoke exhaust pipe 5 and pipeline 7 valve plate 9 is installed respectively again.During work, after the flue gas of combustion chamber 1 is collected through smoke collecting chamber body 4, enter filter chamber 10 after filtering by filter 6, detect the impurity that filters the back flue gas then, if flue gas impurity parameter is up to standard, the valve plate 9 of opening conduits 7 then, flue gas enters heat exchanger 2; If filtered smoke gas impurity is still too much, then directly by smoke exhaust pipe 5 dischargings.This deformed configurations also can realize the purpose of this utility model, just needs frequent filter rinsed 6.
