TECHNICAL FIELD

[0001] The utility model relates to a spray type saturator technical field, specifically is a saturator spraying device. BACKGROUND

[0002] The working principle of the spray type saturator of the coal gas purification system is that ammonium sulfate mother liquor is used to spray the coal gas purified by the primary cooler and the electric tar precipitator to absorb the ammonia mixed in the coal gas. After continuous spraying of the ammonium sulfate mother liquor, the ammonia in the coal gas reacts with the ammonium sulfate mother liquor to generate saturated ammonium sulfate mother liquor, and the ammonium sulfate crystal particles are extracted from the bottom of the spray type saturator. In order to make the spray mother liquor fully contact with the coal gas, it is required that the unit spray mother liquor has a larger gas-liquid contact surface, and the spray mother liquor droplets are finer.

[0003] However, the existing technology ammonium sulfate mother liquor enters the annular channel formed by the coal gas channel cover plate, the mother liquor channel cover plate and the inner and outer ring plates, and is sprayed by the spraying device arranged on the coal gas channel ring plate. Since the coal gas channel cover plate and the mother liquor channel cover plate are flat plates, the stress structure is not good, and under the action of the ammonium sulfate mother liquor pressure, the flat plate may be deformed, the mother liquor may be leaked, and the ammonium sulfate mother liquor may directly enter the lower coal gas cavity without uniform spraying, thereby affecting the absorption effect.

[0039] like Figure 1-9 As shown, a saturator spraying device includes an ammonium sulfate mother liquor inlet 1, a ring pipe 2, a first branch pipe 3, an ultrasonic flowmeter 4, a valve 5, an atomizing nozzle 6, a mounting port 7, a flange cover 8 and a second branch pipe 9.

[0040] The saturator body is a vertical structure with a vertical axis. A horizontal annular pipe 2 surrounds and is fixed to the exterior of the saturator body, distributing the ammonium sulfate mother liquor. An ammonium sulfate mother liquor inlet 1 is horizontally disposed and communicates with the annular pipe 2.

[0041] Multiple branch pipes are evenly distributed around the annular tube 2. One end of each branch pipe is connected to the annular tube 2, and the other end extends through the gas channel cover 10 into the gas channel. Atomizing nozzle 6 is fixed to the other end of the branch pipe. In this embodiment, there are 16 branch pipes, symmetrically distributed on each side, with 8 on each side. The angles between the branches on each side are the same.

[0042] The branch pipes include a first branch pipe 3 and a second branch pipe 9, both of which are L-shaped. The top of the vertical pipe of the first branch pipe 3 is fixed to the bottom of the annular pipe 2 to reduce the deposition of ammonium sulfate mother liquor in the annular pipe 2. An ultrasonic flowmeter 4 and a valve 5 are installed on the horizontal pipe of the first branch pipe 3. The vertical pipe of the second branch pipe 9 passes through the gas channel cover plate 10. The atomizing nozzle 6 is fixed to the end of the horizontal pipe of the second branch pipe 9, with the nozzle facing the direction of gas flow.

[0043] The ultrasonic flowmeter 4 is an external ultrasonic flowmeter that measures the flow rate of each branch pipe and adjusts the opening of the valve 5 to ensure that the flow rate of each branch pipe meets the design requirements. During operation, if the flow rate decreases significantly, it may be due to nozzle blockage. Close the valve 5 and remove the nozzle for cleaning.

[0044] Flange cover 8 is horizontally welded to the vertical outer wall of second branch pipe 9, and mounting port 7 is fixed to the top surface of gas channel cover plate 10. Atomizing nozzle 6 is placed in the gas channel through mounting port 7, spraying in the opposite direction of the gas. Flange cover 8 and mounting port 7 are connected with bolts.

[0045] The atomizing nozzle 6 includes a housing 61 , a rotary core 62 and a screw 63 . The rotary core 62 is placed in the housing 61 and fixed by the screw 63 .

[0046] The housing 61 is composed of an internal threaded barrel 611, a first cylindrical barrel 612, a second cylindrical barrel 613, an inverted tapered barrel 614, a cylindrical barrel 615 and a smooth tapered barrel 616. The internal threaded barrel 611 is provided with an internal thread for threaded connection with the second branch pipe 9.

[0047] The sidewall of the first cylindrical barrel 612 is provided with a threaded hole. The inner diameter of the first cylindrical barrel 612 is slightly larger than the outer diameter of the spin core 62. The spin core 62 is placed inside the first cylindrical barrel 612 and secured with screws 63. The inner diameter of the second cylindrical barrel 613 is slightly smaller than that of the spin core 62. The second cylindrical barrel 613 serves as a support for the spin core 62 and also serves as the mixing chamber for the entire nozzle.

[0048] The core 62 is circular, with a cylindrical straight liquid channel at its center, allowing liquid to enter the mixing chamber directly. Six inclined channels, evenly distributed around its outer circumference, allow liquid to enter the mixing chamber along these spiral channels. The inclined channels are inclined at angles of 30 to 80 degrees, ensuring excellent uniformity and atomization of all liquid components.

[0049] Ammonium sulfate mother liquor enters annular pipe 2 through ammonium sulfate mother liquor inlet 1, flows along first branch pipe 3, valve 5, and second branch pipe 9, and enters atomizing nozzle 6. The flow rate in each branch pipe is measured by an external ultrasonic flowmeter 4, and the opening of valve 5 is adjusted to ensure that the flow rate in each branch pipe meets the design requirements. If the flow rate decreases significantly during operation, it may be due to nozzle blockage. Close valve 5 and remove the nozzle for cleaning. Under normal operating conditions, the saturator absorbs ammonia from the coal gas and meets process requirements.

[0050] The present invention uses an annular tube 2 to distribute ammonium sulfate mother liquor, which has good stress resistance and is not easy to leak. It is located outside the equipment, so leaks can be detected. The present invention is equipped with an ultrasonic flowmeter 4 and a valve 5. The ultrasonic flowmeter 4 and valve 5 are installed on the branch pipe. By measuring the flow of each branch pipe, the opening of the valve 5 is adjusted to ensure that the flow of each branch pipe meets the design requirements, and the flow of each nozzle is consistent and sprayed evenly. It can detect nozzle blockage and repair the nozzle; during operation, if the flow rate decreases significantly, it is possible that the nozzle is blocked. The valve 5 is closed and the nozzle is removed for cleaning. The present invention uses an atomizing nozzle 6 to ensure the atomization effect and improve the absorption efficiency. The branch pipe of the present invention is connected from the bottom of the annular tube 2, which is conducive to reducing the deposition of ammonium sulfate mother liquor in the annular tube. The spiral core 62 of the atomizing nozzle 6 of the present invention is circular, with a cylindrical liquid straight channel in the center. The liquid enters the mixing chamber directly. Multiple inclined channels are evenly distributed on the outer circumference. The liquid enters the mixing chamber along the spiral channel. It can achieve good uniformity and ensure that all components of the liquid can be evenly atomized.

[0051] The above description is only part of the specific implementation methods of the present invention, and the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and the utility model concept of the present invention, should be covered by the protection scope of the present invention.
