Description

Technical Field

[0001] The utility model belongs to the technical field of combustion, and in particular relates to an oxygen-enriched full combustion device for carbide slag cement kiln. Background Art

[0002] Oxygen enrichment is widely used in various fuel oil, gas, coal-fired kilns (glass, cement, ceramics), various boilers, heating furnaces, incinerators, hot coal furnaces, hot air furnaces, smelting furnaces, aircraft engines, ship engines and other combustion-supporting energy conservation and environmental protection; oxygen enrichment technology has also been applied in catalytic cracking, desulfurization, wastewater treatment, engine efficiency enhancement, oxygen-enriched (coal) gas production, various oxidation reactions, fermentation and other fields to achieve good economic benefits.

[0003] However, carbide slag cement kilns currently generally have problems such as low thermal efficiency, excessive harmful gas CO, and the generation of nitrogen oxides, which cause gas emissions to pollute the environment due to the unburned solids carried in the exhaust flue gas. Summary of the invention

[0004] In view of the deficiencies in the prior art, the utility model aims to provide an oxygen-enriched full combustion device for carbide slag cement kiln, which solves the problem of gas emission polluting the environment.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an oxygen-enriched full combustion device for a carbide slag cement kiln, comprising a base plate, a cooler is fixedly installed on the top of the base plate, a burner is fixedly installed on the top of the base plate, a motor is fixedly installed on the bottom of the burner, a combustion chamber is fixedly installed on the output end of the motor, a cooling pipe is fixedly installed on the inside of the burner, a liquid oxygen storage tank is fixedly installed on the top of the base plate, a liquid oxygen storage tank switch is fixedly installed on the top of the liquid oxygen storage tank, an exhaust gas processor is fixedly installed on the top of the base plate, a pressure gauge is fixedly installed on the front of the exhaust gas processor, a button is fixedly installed on the front of the exhaust gas processor, and an observation window is fixedly installed on the front of the exhaust gas processor and is located directly below the button.

[0006] Preferably, four pillars are fixedly installed at the four corners of the bottom of the burner, and four supporting columns are fixedly installed at the four corners of the bottom of the exhaust gas processor.

[0007] The above technical solution has the advantage that four pillars and four supporting columns respectively support the entire burner and the exhaust gas processor. The burner and the exhaust gas processor will generate a large amount of hot air during operation, so that their bottoms are not in direct contact with the ground, which can play a certain heat dissipation role.

[0008] Preferably, the cooler is connected to a connecting pipe, and the other end of the connecting pipe is connected to a cooling pipe.

[0009] The above technical solution has the advantage that the cooler forms a coolant, which then flows into the connecting pipe and finally into the cooling pipe to cool the burner. This protects the burner from overheating and damaging the equipment.

[0010] Preferably, an igniter is fixedly mounted on the top of the burner.

[0011] The above technical solution has the advantage that when oxygen enters the burner and the igniter is subsequently started, the items inside the combustion chamber can be burned without the need for the staff to open the burner for combustion, thereby increasing the safety of the staff.

[0012] Preferably, a heat dissipation groove is provided on one side of the exhaust gas processor.

[0013] The above technical solution has the advantage that a large amount of hot air will be generated during the operation of the exhaust gas processor. If it is exposed to hot air for a long time, it may affect the service life of the exhaust gas processor. Therefore, the heat sink plays a role in heat dissipation for the exhaust gas processor, thereby increasing the service life of the exhaust gas processor.

[0014] Preferably, the burner and the liquid oxygen storage tank are connected to each other via an oxygen pipe.

[0015] The advantage of the above technical solution is that when the object to be burned is placed inside the combustion chamber, the oxygen in the liquid oxygen storage tank is transmitted to the burner through the oxygen pipe, and then the igniter is started to burn it. Without oxygen, it cannot burn.

[0016] Preferably, the burner and the exhaust gas processor are connected to each other via an air pipe.

[0017] The advantage of the above technical solution is that some harmful gases will be generated after the objects are burned. This gas cannot be directly discharged into the environment, which will pollute the environment and affect the health of the workers. The gas can be passed into the exhaust gas processor through the air pipe for treatment.

[0018] Preferably, an exhaust port is fixedly mounted on one side of the exhaust gas processor.

[0019] The above technical solution has the advantage that the gas generated after combustion enters the exhaust gas processor through the air pipe, where the gas is processed and then discharged from the exhaust port after the processing is completed, thus avoiding environmental pollution.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] 1. Through the setting of the motor, the combustion chamber is fixed at the output end of the motor, and the combustion chamber can rotate with the motor. The liquid oxygen storage tank transmits oxygen to the inside of the burner through the oxygen pipe. Through the rotation of the combustion chamber, the oxygen in every place inside the burner can be almost uniform, because only places with oxygen can burn. Through the rotation of the combustion chamber, the mixing between oxygen and combustion materials is promoted, the combustion speed is increased, and the work efficiency is improved.

[0022] 2. Through the setting of cooler, because the burner will generate a lot of heat during operation, although the outer shell of the burner is made of fireproof material, the burner has been in a high temperature state for a long time, which will affect the service life of the burner. With the existence of cooler, the burner can be cooled down slowly, not quickly, which will not affect the service life of the burner. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described implementation scheme is only a part of the implementation scheme of the utility model, not all the implementation schemes. Based on the implementation scheme in the utility model, all other implementation schemes obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] like Figure 1-Figure 4As shown, an oxygen-enriched full combustion device for a carbide slag cement kiln includes a base plate 1, a cooler 3 is fixedly installed on the top of the base plate 1, a burner 8 is fixedly installed on the top of the base plate 1, a motor 5 is fixedly installed on the bottom of the burner 8, a combustion chamber 19 is fixedly installed on the output end of the motor 5, a cooling pipe 20 is fixedly installed on the inner side of the burner 8, a liquid oxygen storage tank 7 is fixedly installed on the top of the base plate 1, a liquid oxygen storage tank switch 18 is fixedly installed on the top of the liquid oxygen storage tank 7, an exhaust gas processor 12 is fixedly installed on the top of the base plate 1, a pressure gauge 14 is fixedly installed on the front of the exhaust gas processor 12, a button 15 is fixedly installed on the front of the exhaust gas processor 12, and an observation window 16 is fixedly installed on the front of the exhaust gas processor 12 and is located directly below the button 15.

[0030] The working principle of the above technical solution is as follows:

[0031] First, the staff places the items to be burned in the combustion chamber 19, and then transports the oxygen in the liquid oxygen storage tank 7 to the burner 8 through the oxygen pipe 9, and then starts the motor 5, which drives the combustion chamber 19 to rotate, and then uses the igniter 10 to burn the combustion chamber 19. The gas generated after combustion enters the exhaust gas processor 12 from the air pipe 11. The staff can check it through the pressure gauge 14, and can also check the situation inside the exhaust gas processor 12 through the observation window 16. The treated gas can be directly discharged through the exhaust port 13, and then the cooler 3 is started, and the generated coolant enters the cooling pipe 20 through the connecting pipe 4, so as to cool down the inside of the burner 8 and increase the service life of the burner 8.

[0032] In another embodiment, Figure 1-4 As shown, four pillars 6 are fixedly installed at the four corners of the bottom of the burner 8, and four supporting columns 2 are fixedly installed at the four corners of the bottom of the exhaust gas processor 12.

[0033] The four pillars 6 and the four support pillars 2 respectively support the entire burner 8 and the exhaust gas processor 12. The burner 8 and the exhaust gas processor 12 will generate a large amount of hot air during operation. Keeping their bottoms from directly contacting the ground can play a certain heat dissipation role.

[0034] In another embodiment, Figure 1-4 As shown, the cooler 3 is connected to a connecting pipe 4 , and the other end of the connecting pipe 4 is connected to a cooling pipe 20 .

[0035] The cooler 3 forms a coolant, which then flows into the connecting pipe 4 and finally flows into the cooling pipe 20 to cool the burner 8. This protects the burner 8 from overheating and damaging the equipment.

[0036] In another embodiment, Figure 1-4As shown, an igniter 10 is fixedly mounted on the top of the burner 8.

[0037] When oxygen enters the burner 8, the igniter 10 is then started, and the items inside the combustion chamber 19 can be burned without the need for the staff to open the burner 8 for combustion, thereby increasing the safety of the staff.

[0038] In another embodiment, Figure 1-4 As shown, a heat dissipation groove 17 is provided on one side of the exhaust gas processor 12 .

[0039] The exhaust gas processor 12 will generate a large amount of hot air during operation. If it is exposed to hot air for a long time, the service life of the exhaust gas processor 12 may be affected. Therefore, the heat dissipation groove 17 plays a role in heat dissipation for the exhaust gas processor 12, thereby increasing the service life of the exhaust gas processor 12.

[0040] In another embodiment, Figure 1-4 As shown, the burner 8 and the liquid oxygen storage tank 7 are connected to each other via an oxygen pipe 9.

[0041] When the object to be burned is placed inside the combustion chamber 19, the oxygen in the liquid oxygen storage tank 7 is transmitted to the burner 8 through the oxygen pipe 9, and then the igniter 10 is started to burn it. Without oxygen, it cannot burn.

[0042] In another embodiment, Figure 1-4 As shown, the burner 8 and the exhaust gas processor 12 are connected to each other via an air pipe 11.

[0043] After the objects are burned, some harmful gases will be generated. This gas cannot be discharged directly into the environment, as it will pollute the environment and affect the health of the workers. The gas can be introduced into the exhaust gas processor 12 through the air pipe 11 for treatment.

[0044] In another embodiment, Figure 1-4 As shown, an exhaust port 13 is fixedly mounted on one side of the exhaust gas processor 12 .

[0045] The gas generated after combustion enters the exhaust gas processor 12 through the air pipe 11, where the gas is processed and then discharged from the exhaust port 13 after the processing is completed, thereby avoiding environmental pollution.

[0046] The working principle and use process of the utility model are as follows: first, the staff places the items to be burned in the combustion chamber 19, and then transports the oxygen in the liquid oxygen storage tank 7 to the burner 8 through the oxygen pipe 9, and then starts the motor 5, the motor 5 drives the combustion chamber 19 to rotate, and then uses the igniter 10 to burn the combustion chamber 19, and the gas generated after combustion enters the exhaust gas processor 12 from the air pipe 11. The staff can check it through the pressure gauge 14, and can also check the internal situation of the exhaust gas processor 12 through the observation window 16. The treated gas can be directly discharged through the exhaust port 13, and then the cooler 3 is started, and the generated coolant enters the cooling pipe 20 through the connecting pipe 4, so as to cool down the inside of the burner 8 and increase the service life of the burner 8.

[0047] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
