Description

Technical Field

[0001] The utility model belongs to the technical field of solid sodium carbonate production equipment, and in particular relates to a switchable solid sodium carbonate production device. Background Art

[0002] Sodium silicate is also known as sodium silicate and water glass. The raw materials for producing sodium silicate are quartz sand and soda ash. The two are mixed in a certain proportion and sent to a reverberatory kiln. After high-temperature calcination and water quenching in a melting furnace, they are packaged to form solid sodium silicate. Solid sodium silicate is convenient for transportation and storage.

[0003] During the calcination process of sodium silicate, a large amount of high-temperature flue gas will be generated in the kiln. At the same time, the combustion of the burner also requires a large amount of combustion-supporting air, that is, intake air. The usual practice is to use an electric fan to guide the air into the kiln and discharge the high-temperature flue gas directly through the chimney, which causes a lot of heat waste and is not environmentally friendly. Utility Model Content

[0004] The purpose of the utility model is to provide an energy-saving and environmentally friendly solid that can increase combustion-supporting wind to make combustion more complete, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A switchable solid sodium carbonate production device comprises a combustion chamber, wherein the combustion chamber is respectively connected to a first heat storage chamber and a second heat storage chamber, wherein the first heat storage chamber and the second heat storage chamber can absorb heat or heat air flowing through, wherein the first heat storage chamber is connected to a first air inlet fan at a side away from the combustion chamber, and the combustion chamber is connected to a first burner at a side close to the first heat storage chamber; wherein the second heat storage chamber is connected to a second air inlet fan at a side away from the combustion chamber, and the combustion chamber is connected to a second burner at a side close to the second heat storage chamber.

[0007] The raw materials are placed in the combustion chamber, and then the air inlet fan is turned on to suck air through the heat storage chamber into the combustion chamber as combustion-supporting air, and then the burner is ignited to spray a horseshoe-shaped flame to heat the raw materials.

[0008] The production device is provided with two air flow channels, and burners, heat storage chambers and air inlets are respectively provided on the two air flow channels. When the first burner is ignited, the first air inlet is turned on, and the air flows through the first heat storage chamber and passes through the first burner as combustion-supporting air, while the high-temperature flue gas generated by the combustion flows out from another flow channel, flows through the second heat storage chamber, and heats the second heat storage chamber; when the first burner is turned off and the second burner is ignited, the first air inlet is turned off and the second air inlet is turned on, and the flow of air is switched. Cold air is sucked by the second air inlet, passes through the heated second heat storage chamber, and is sent to the second burner as combustion-supporting air. When the air passes through the second heat storage chamber, it is heated by the second heat storage chamber to become high-temperature air. The high-temperature air helps the combustion of the fuel in the burner, can increase the combustion temperature, and enhance the combustion effect. At this time, the high-temperature flue gas after combustion passes through and flows out of the first heat storage chamber, and the high-temperature flue gas heats the first heat storage chamber again. By utilizing the heat alternation between high-temperature flue gas and the heat storage chamber, the burner is always supported by high-temperature air during combustion, which increases the combustion effect and efficiency.

[0009] Furthermore, the combustion chamber is connected with a first flow channel and a second flow channel, wherein the first flow channel connects the first burner, the first heat storage chamber and the first air inlet fan; and the second flow channel connects the second burner, the second heat storage chamber and the second air inlet fan. The first flow channel and the second flow channel serve as air flow channels, and by switching the air in and out of the first flow channel and the second flow channel, the air and the high-temperature flue gas are alternately heated to continuously provide high-temperature combustion-supporting air for the combustion of the burner.

[0010] Furthermore, the first flow channel is connected to a tail gas chimney at the rear end opposite to the combustion chamber, and the second flow channel is connected to the tail gas chimney at the rear end opposite to the combustion chamber. The tail gas chimney is used to discharge cold flue gas, and the tail gas chimney has the functions of extension and convergence.

[0011] Furthermore, the first burner is arranged beside the flow channel opening of the first flow channel, and its injection direction is toward the combustion chamber; the second burner is arranged beside the flow channel opening of the second flow channel, and the injection directions of the first burner and the second burner are consistent, so that the high-temperature air ejected from the flow channel opening is as close to the burner as possible to improve the combustion efficiency.

[0012] Furthermore, the first heat storage chamber and the second heat storage chamber are provided with honeycomb bricks. The honeycomb bricks have two elements, namely, a honeycomb structure and a brick material. The honeycomb structure increases the contact area between the air and the honeycomb bricks, thereby increasing the thermal conductivity. The brick material dissipates heat slowly, and can store heat for a longer period of time.

[0013] Furthermore, the combustion chamber is connected with a first raw material inlet and a second raw material inlet, wherein the first raw material inlet is arranged at the injection port of the first burner; and the second raw material inlet is arranged at the injection port of the second burner. The first raw material inlet and the second raw material inlet are used for feeding.

[0014] Furthermore, the combustion chamber is also connected to a material outlet, and the material outlet is arranged on a side of the combustion chamber opposite to the injection direction of the first burner. The material outlet is used to discharge the combustion products in the combustion chamber.

[0015] Furthermore, a Y-shaped tube is connected to the side wall of the exhaust chimney, a main valve is provided on the main channel of the Y-shaped tube, a branch valve is connected to one of the branch channels of the Y-shaped tube, an exhaust fan is connected to the other branch channel of the Y-shaped tube, the working direction of the exhaust fan is perpendicular to the branch channel, and the branch channel is provided with a protective cover in the air outlet direction of the exhaust fan. The function of the exhaust fan is to increase the suction force of the chimney, and the exhaust fan rotates when the main valve is opened to increase the suction force, and the exhaust fan does not work when the main valve and the branch valve are opened.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The first flow channel and the second flow channel are connected to the combustion chamber, and the first burner, the first heat storage chamber and the first air inlet fan are arranged in the first flow channel, and the second burner, the second heat storage chamber and the second air inlet fan are arranged on the second flow channel. The inlet and outlet flow channels of air and flue gas are switched by opening and closing the burner and the air inlet fan, so that air and flue gas alternately enter and exit the two flow channels. Since the heat storage chamber has a good heat storage function, heat exchange is achieved between the air and the heat storage chamber, so that the burner is always accompanied by high-temperature air as combustion-supporting wind when working, so that the fuel sprayed by the burner can be burned more completely, the combustion efficiency is improved, and harmful gases are reduced.
