Description

A waste gas incinerator

technical field

The utility model belongs to the technical field of waste gas treatment equipment, in particular to a waste gas incinerator.

Background technique

At present, the toxic, harmful and odorous waste gas produced in the production process of chemical industry, printing and dyeing industry, etc., the waste gas has caused great harm to the human body and polluted the atmosphere. Therefore, it is necessary to treat the waste gas into harmless gas before allowing it to be discharged. The gaseous organic compounds are generally treated by incineration, and the incineration process is the most common, effective and lowest-cost waste gas treatment process.

The incineration process will generate a large amount of heat while processing the exhaust gas. The existing incinerators do not make reasonable use of the heat generated, resulting in waste of heat. A large amount of low-temperature exhaust gas entering the incineration chamber will cause the incineration room to be too low. Waste gas incineration treatment Insufficient, so there is an urgent need for a waste gas incinerator with a built-in heat energy recovery device.

Utility model content

In order to solve the above problems, the utility model provides a waste gas incinerator. The utility model has the advantages of simple structure, high processing efficiency during operation, low cost, less energy consumption, short time consumption, and stable incineration effect.

The technical solution of the utility model is:

An exhaust gas incinerator, comprising a combustion chamber and a settling chamber, the front end of the combustion chamber is provided with an exhaust gas inlet and an auxiliary combustion air inlet, the bottom of the rear end is connected to the bottom of the front end of the settling chamber, and the top of the settling chamber is provided with a purified gas discharge port , an auxiliary burner is arranged in the auxiliary combustion air inlet;

The inner wall of the combustion chamber is coated with heat-insulating refractory materials, and the combustion chamber is provided with burners, gas retaining walls, and refractory brick heat storage walls. Divide the combustion chamber into tortuous gas passages; the refractory brick heat storage wall is built between two adjacent gas retaining walls, the combustion chamber and the settling exterior are wrapped with a fire-resistant insulation layer, and the combustion There is also a dust-cleaning door on the chamber and the settling chamber.

The number of the gas barrier is at least three layers.

There are at least two refractory brick heat storage walls, and the refractory brick heat storage walls are respectively staggered inside the combustion chamber.

The beneficial effects of the utility model are: simple structure, convenient operation; low energy consumption, less time consumption; It meets the treatment requirements of various polluted waste gases without affecting the operation effect, and is easy to clean and clean.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

As shown in Figure 1, the utility model is achieved in this way, a waste gas incinerator includes a combustion chamber (7) and a settling chamber (8), and the front end of the combustion chamber (7) is provided with a waste gas inlet (1) and an auxiliary combustion chamber The air inlet (3), the bottom of the rear end communicates with the bottom of the front end of the settling chamber (8), the top of the settling chamber (8) is provided with a purified gas discharge port (9), and the auxiliary combustion air inlet (3) is provided in the mouth auxiliary burner (2);

The inner wall of the combustion chamber (7) is coated with heat-insulating refractory material, and a burner (11), a gas retaining wall (4), and a refractory brick heat storage wall (5) are arranged in the combustion chamber 7, and the burner (11) is located at At the bottom of the combustion chamber (7), the gas retaining walls (4) are staggered along the combustion chamber (7) to separate the interior of the combustion chamber (7) into tortuous gas passages; the refractory brick heat storage wall (5) Built between two adjacent gas retaining walls (4), the combustion chamber (7) and the settling chamber (8) are wrapped with a fire-resistant and heat-insulating layer (10).

The number of the gas retaining wall (4) is at least three layers.

There are at least two refractory brick heat storage walls (5), and the refractory brick heat storage walls (5) are respectively arranged in a staggered manner inside the combustion chamber.

The combustion chamber (7) and the settling chamber (8) are respectively provided with a dust removal door (4), and the dust removal door (4) is used for regularly opening and cleaning deposits in the incinerator.

The purified gas discharge port (9) is the discharge outlet of the purified gas up to the standard after the exhaust gas is incinerated completely, and a hot air heat exchanger is designed and installed at the outlet;

The incinerator of the utility model adopts a steel structure to ensure the rigidity requirements of the incinerator structure; in the combustion chamber (7), exhaust gas is burned in contact with the flame of the burner (11), and the furnace is designed for normal pressure operation.

The working process is as follows:

Firstly, check that the connection of each pipeline system is normal, that there is no leakage of natural gas, and that the pressure is normal; turn on the auxiliary burner (2), turn on the ignition switch of the burner (11), and the burner (11) will automatically ignite and run; wait in the combustion chamber (7) After the temperature rises to 400 degrees Celsius, the auxiliary combustion air inlet (3) is opened to supply air to the incinerator; the exhaust gas and the flame of the burner (11) are contacted and burned in the combustion chamber (7) of the incinerator, and the refractory bricks in the combustion chamber (7) store heat The wall (5) ensures the uniformity and stability of the temperature of the entire combustion chamber (7) to achieve the purpose of forcing the combustion temperature of the waste gas and making the waste gas completely combustible. The combustion waste gas enters the dust-falling chamber (8) under the condition of wind direction thrust, and after settling, the waste gas passes through the hot air heat exchanger and discharges the purified gas up to the standard from the purified gas discharge port (9).

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any person familiar with the technical field can easily think of All changes or replacements should fall within the protection scope of the present utility model.
