Description

Technical Field

[0001] The invention relates to the technical field of spray-type saturators, and in particular to a saturator spraying device. Background Art

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

[0003] However, in the prior art, the ammonium sulfate mother liquor enters the annular channel formed by the gas channel cover plate, the mother liquor channel cover plate and the inner and outer ring plates, and enters the spraying device arranged on the gas channel ring plate for spraying. Since the gas channel cover plate and the mother liquor channel cover plate are both flat plates with poor force-bearing structure, the plates may be deformed and the mother liquor may leak under the pressure of the ammonium sulfate mother liquor, causing the ammonium sulfate mother liquor to directly enter the lower gas cavity without uniform spraying, thus affecting the absorption effect. Summary of the invention

[0004] In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a saturator spraying device, which adopts an annular tube to distribute the ammonium sulfate mother liquor, has good force resistance, is not easy to leak, and is located outside the equipment, so leakage can be detected.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A saturator spraying device comprises an ammonium sulfate mother liquor inlet, an annular tube, a branch pipe and a nozzle; the ammonium sulfate mother liquor inlet is connected to the annular tube, the annular tube surrounds and is fixedly connected to the outside of the saturator body, and the annular tube distributes the ammonium sulfate mother liquor; a plurality of branch pipes are evenly distributed around the annular tube, one end of the branch pipe is connected to the annular tube, and the other end passes through a gas channel cover plate and extends into the gas channel, and the nozzle is fixedly connected to the other end of the branch pipe.

[0007] Furthermore, it also includes an ultrasonic flow meter and a valve, which are installed on the branch pipe, and the opening of the valve is adjusted according to the flow measured by the ultrasonic flow meter.

[0008] Furthermore, the ultrasonic flowmeter is an external ultrasonic flowmeter.

[0009] Furthermore, the branch pipe is fixedly connected to the bottom of the annular pipe.

[0010] Furthermore, the branch pipe includes a first branch pipe and a second branch pipe, and the first branch pipe and the second branch pipe are both L-shaped.

[0011] Furthermore, it also includes a mounting port and a flange cover. The mounting port is fixedly connected to the gas channel cover plate. The nozzle is placed in the gas channel through the mounting port to spray in the opposite direction to the gas. The flange cover is fixedly connected to the branch pipe, and the mounting port and the flange cover are connected by bolts.

[0012] Furthermore, the nozzle is an atomizing nozzle.

[0013] Furthermore, the atomizing nozzle includes a shell, a rotary core and a screw, and the rotary core is placed in the shell and fixed by the screw.

[0014] Furthermore, the shell is composed of an internal threaded cylinder, a first cylindrical cylinder, a second cylindrical cylinder, an inverted tapered cylinder, a cylindrical cylinder and a smooth tapered cylinder from top to bottom; the internal threaded cylinder is connected to the branch pipe, the inner diameter of the first cylindrical cylinder is larger than the outer diameter of the swirl core, the swirl core is placed in the first cylindrical cylinder, and the inner diameter of the second cylindrical cylinder is smaller than the outer diameter of the swirl core; the second cylindrical cylinder supports the swirl core and is the mixing chamber of the nozzle.

[0015] Furthermore, the spiral core is circular, with a cylindrical straight liquid channel in the center, and the liquid directly enters the mixing chamber. There are multiple inclined channels evenly distributed on the outer circumference, and the liquid enters the mixing chamber along the spiral channel; the inclination angle of the inclined channel is 30 to 80 degrees.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The inlet of the ammonium sulfate mother liquor of the present invention is connected to the annular tube, which surrounds and is fixedly connected to the outside of the saturator mother body, and the annular tube distributes the ammonium sulfate mother liquor. The annular tube is used to distribute the ammonium sulfate mother liquor, which has good stress resistance and is not easy to leak. Moreover, the annular tube is located outside the equipment, so leakage can be found.

[0018] 2. The present invention is provided with an ultrasonic flowmeter and a valve, which are installed on the branch pipe. By measuring the flow of each branch pipe and adjusting the opening of the valve, the flow of each branch pipe is ensured to meet the design requirements, and the flow of each nozzle is ensured to be consistent and sprayed evenly. The nozzle blockage can be detected and the nozzle can be repaired; during operation, if the flow rate becomes significantly smaller, the nozzle may be blocked, and the valve is closed and the nozzle is taken out for cleaning.

[0019] 3. The present invention adopts an atomizing nozzle to ensure the atomization effect and improve the absorption efficiency.

[0038] 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 flow meter 4, a valve 5, an atomizing nozzle 6, a mounting port 7, a flange cover 8 and a second branch pipe 9.

[0039] The saturator body is a vertical structure with a vertical axis. The annular pipe 2 is horizontally arranged, surrounds and is fixedly connected to the outside of the saturator body, and distributes ammonium sulfate mother liquor. The ammonium sulfate mother liquor inlet 1 is horizontally arranged and communicated with the annular pipe 2.

[0040] Multiple branch pipes are evenly distributed around the annular pipe 2. One end of the branch pipe is connected to the annular pipe 2, and the other end passes through the gas channel cover 10 and extends into the gas channel. The atomizing nozzle 6 is fixed to the other end of the branch pipe. In this embodiment, there are 16 branch pipes, 8 on each side and symmetrically distributed, and the angles between the branch pipes on each side are the same.

[0041] The branch pipe includes 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 liquid in the annular pipe 2. The ultrasonic flowmeter 4 and the 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, and the atomizing nozzle 6 is fixed to the end of the horizontal pipe of the second branch pipe 9, and the direction of the nozzle is opposite to the gas flow direction.

[0042] The ultrasonic flowmeter 4 is an external ultrasonic flowmeter. 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. During operation, if the flow rate decreases significantly, it may be that the nozzle is blocked. Close the valve 5 and take out the nozzle for cleaning.

[0043] The flange cover 8 is horizontally welded to the vertical outer wall of the second branch pipe 9, and the mounting port 7 is fixed to the top surface of the gas channel cover plate 10. The atomizing nozzle 6 is placed in the gas channel through the mounting port 7 to spray against the gas, and the flange cover 8 and the mounting port 7 are connected by bolts.

[0044] The atomizing nozzle 6 comprises 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 .

[0045] 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.

[0046] The side wall of the first cylindrical barrel 612 is provided with a threaded hole, and the inner diameter of the first cylindrical barrel 612 is slightly larger than the outer diameter of the rotary core 62. The rotary core 62 is placed in the first cylindrical barrel 612 and fixed by screws 63. The inner diameter of the second cylindrical barrel 613 is slightly smaller than the rotary core 62.

The flow rate of each branch pipe is measured by the external ultrasonic flowmeter 4, and the opening of the valve 5 is adjusted to ensure that the flow rate of each branch pipe meets the design requirements. During operation, the flow rate becomes significantly smaller, which may be caused by nozzle blockage. Close the valve 5 and take out the nozzle for cleaning. Under normal operating conditions, the saturator absorbs ammonia in the coal gas to meet the process requirements.

[0049] The present invention adopts an annular tube 2 to distribute ammonium sulfate mother liquor, which has good stress and is not easy to leak. It is located outside the equipment and can detect leakage. The present invention is provided with an ultrasonic flowmeter 4 and a valve 5, which are installed on the branch pipe.

It can detect nozzle blockage and repair the nozzle; during operation, if the flow rate is significantly reduced, the nozzle may be blocked, and the valve 5 is closed and the nozzle is taken out for cleaning. The present invention adopts 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 lower part 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, and the liquid directly enters the mixing chamber. There are multiple inclined channels evenly distributed on the outer circumference, and 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.
