DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the organic waste liquid treatment system of the utility model is further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] like Figure 1 As shown, a system for treating organic waste liquid comprises: a coal gasifier 1 and a first connecting pipe 2, a liquid inlet 3 for allowing external waste liquid to enter the inner cavity of the coal gasifier 1 is arranged on the top wall of the coal gasifier 1, one end of the first connecting pipe 2 is connected to the liquid inlet 3, and the other end can be connected to an external waste liquid source, so that the organic waste liquid in the external waste liquid source can enter the inner cavity of the coal gasifier 1 through the first connecting pipe 2 to undergo a gasification reaction in a reducing atmosphere. By adopting such a technical scheme, the organic waste liquid can be treated by the organic waste liquid undergoing a gasification reaction in the coal gasifier 1, which not only has a fast treatment speed, but also reduces the energy consumption of treating the organic waste liquid, and can also reduce the secondary pollution caused by treating the organic waste liquid. Since the gas generated by the organic waste liquid during the gasification reaction in the coal gasifier 1 can supplement the components of the synthesis gas produced by the coal gasifier 1, such a treatment method can also achieve resource utilization of the organic waste liquid.

[0027] Furthermore, if Figure 1As shown, it also includes a second connecting pipe 4 and a heating device 5. The heating device 5 is connected to an external waste liquid source through the second connecting pipe 4. The end of the first connecting pipe 2 away from the coal gasification furnace 1 is connected to the heating device 5, so that the organic waste liquid in the external waste liquid source can enter the heating device 5 through the second connecting pipe 4 for heating, and then enter the inner cavity of the coal gasification furnace 1 through the first connecting pipe 2. The use of such a technical solution can reduce the viscosity of the organic waste liquid by heating the organic waste liquid, thereby improving the flowability of the organic waste liquid, so that it can smoothly enter the inner cavity of the coal gasification furnace 1 through the liquid inlet hole 3. In actual production, it can be as follows Figure 1 As shown in , preferably, a temperature monitoring device 7 is provided on the heating device 5 to detect the temperature of the organic waste liquid entering the first connecting pipe 2, and a viscosity monitoring device 8 is provided on the heating device 5 to detect the viscosity of the organic waste liquid entering the first connecting pipe 2. In this way, the working state of the heating device 5 can be adjusted according to the temperature value and viscosity value of the organic waste liquid entering the first connecting pipe 2, thereby avoiding energy waste.

[0028] Preferably, if Figure 1 As shown, a driving pump 6 is provided on the first connecting pipe 2 to move the organic waste liquid in the first connecting pipe 2 toward the inner cavity of the coal gasifier 1. In this way, the organic waste liquid can smoothly enter the inner cavity of the coal gasifier 1 by overcoming the pressure in the inner cavity of the coal gasifier 1 and the atomization resistance of the atomizing nozzle 9 under the driving action of the driving pump 6.

[0029] As an implementation method, Figure 1 , 2 As shown, it also includes a waste liquid nozzle 9, which includes an inner sleeve 10. The inner sleeve 10 is a hollow cylindrical body, and has an inlet 11 and an outlet 12 at both ends of the axial direction. The waste liquid nozzle 9 is inserted into the liquid inlet hole 3, and one end of the inner sleeve 10 with the inlet 11 is located outside the coal gasifier 1, and the other end with the outlet 12 is located in the inner cavity of the coal gasifier 1. The first connecting pipe 2 is connected to the inlet 11, so that the organic waste liquid in the first connecting pipe 2 can enter the inner cavity of the coal gasifier 1 through the inner sleeve 10. In actual production, the inner cavity of the coal gasifier 1 is in the shape of a rotating body, and the number of the liquid inlet hole 3 is at least one. When the number of the liquid inlet holes 3 is at least two, at least two liquid inlet holes 3 are arranged in a circular array with the axis of the inner cavity of the coal gasifier 1 as the center. The number of waste liquid nozzles 9 is equal to the number of liquid inlet holes 3, and they correspond one to one.

[0030] Furthermore, if Figure 1 , 2As shown, the waste liquid nozzle 9 also includes a gas connecting pipe 13, and a jacket 14 and a plugging plate 15. The jacket 14 is a hollow cylindrical body, and its two axial ends are respectively a connecting end 16 and a free end 17. The jacket 14 is sleeved on the inner sleeve 10, and the axes of the two coincide, so that a gas flow channel 18 with a circular cross section is formed between the inner sleeve 10 and the jacket 14. The shape of the plugging plate 15 matches the cross-sectional shape of the gas flow channel 18. The connecting end 16 is sealedly connected to the outer wall of the inner sleeve 10 through the plugging plate 15, and the free end 17 and one end of the inner sleeve 10 with the outlet 12 form an exhaust port 19 of the gas flow channel 18. An air inlet 20 for allowing external gas to enter the gas flow channel 18 is provided on the side wall of the jacket 14. One end of the gas connecting pipe 13 is connected to the air inlet 20, and the other end is connected to an external atomizing gas source, so that the atomizing gas in the external atomizing gas source can enter the gas flow channel 18 through the gas connecting pipe 13 and be discharged to the outside of the gas flow channel 18 through the exhaust port 19. In this way, the atomizing gas discharged from the exhaust port 19 can impact the organic waste liquid discharged from the outlet 12 to atomize the organic waste liquid, thereby making the organic waste liquid burn more completely in the coal gasifier 1.

[0031] Preferably, if Figure 2 As shown, the waste liquid nozzle 9 further includes a guide plate 21, which is disposed in the exhaust port 19 and fixedly connected (can be welded, but not limited to this) to the inner wall of the outer sleeve 14 and / or the outer wall of the inner sleeve 10. With such a technical solution, the atomized gas in the air flow channel 18 can be ejected from the exhaust port 19 in a swirling manner, thereby improving the atomization effect of the organic waste liquid. In actual production, the number of the guide plates 21 is at least two, and at least two guide plates 21 are arranged in a circular array with the axis of the inner sleeve 10 as the center.

[0032] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
