Description

Technical Field

[0001] The utility model relates to a sulfuric acid dilution device, specifically, a tubular acid dispenser used for diluting sulfuric acid in the production process of ammonia compound fertilizer. Background Art

[0002] It is well known in the fertilizer production industry that sulfuric acid solution is required in the production of amino acid compound fertilizer. And sulfuric acid solution needs to be prepared with sulfate mother liquor, water and additives. The traditional preparation method is to use mechanical stirring equipment to mix sulfate mother liquor with water and other additives. Although the preparation of sulfuric acid solution can be achieved by mechanical stirring equipment, the need to equip special mechanical stirring equipment not only requires a lot of equipment investment and energy consumption, but also has high production costs. In addition, the use of mechanical stirring equipment for preparation not only takes a long time, has low production efficiency, but also is difficult to achieve the ideal mixing effect, and it is difficult to ensure the product quality of amino acid compound fertilizer. Utility Model Content

[0003] The problem to be solved by the utility model is to provide a tubular acid dispensing device, which can reduce production costs, improve production efficiency and ensure the product quality of ammonia compound fertilizer.

[0004] The above-mentioned problems to be solved by the utility model are achieved by the following technical solutions:

[0005] The tubular acid dispensing device of the utility model comprises a water inlet pipe and an acid outlet pipe. The utility model is characterized in that the water inlet pipe and the acid outlet pipe are both arranged horizontally, and one end of the water inlet pipe and the acid outlet pipe are connected together in a sealed state. An acid inlet is arranged on the pipe wall of the water inlet pipe, and the acid inlet is connected to an acid inlet pipe which is perpendicular to the longitudinal direction of the water inlet pipe. A nozzle is arranged in the water inlet pipe before the acid inlet, and the front section and rear end of the nozzle are respectively a first circular tube section and a first conical section, and the outer circle of the first circular tube section is connected to the inner wall of the water inlet pipe in a sealed state, and the outer wall of the first conical section corresponds to the acid inlet. A mixing tube is arranged in the water inlet pipe after the acid inlet, and the front section and rear end of the mixing tube are respectively provided with a short conical inlet with a large outside and a small inside and a long conical outlet, and the small end of the first conical section of the nozzle is flush with the short conical inlet of the mixing tube, and a spacing is left around the outer wall of the first conical section of the nozzle and the short conical inlet of the mixing tube.

[0006] Wherein, a sealing ring is connected between the connecting ends of the water inlet pipe and the acid outlet pipe.

[0007] A further improvement of the utility model is that the mixing tube contains a second circular tube section and a second conical section, the second circular tube section is located between the sealing ring and the acid inlet, and the second conical section is located in the acid outlet tube after the sealing ring.

[0008] Both ends of the water inlet pipe, both ends of the acid outlet pipe and the outer end of the acid inlet pipe are provided with flanges. The adjacent ends of the water inlet pipe and the acid outlet pipe are connected together by means of flanges, bolts and nuts. During operation, the water inlet and the acid inlet pipe are connected to the tap water pipe and the acid storage tank respectively by means of corresponding flanges, water pumps and valves.

[0009] A further improvement of the utility model is that the water inlet pipe, the acid outlet pipe and the acid inlet pipe are all provided with acid-resistant lining pipes, and the adjacent ends of adjacent acid-resistant lining pipes are connected together in a sealed state.

[0010] It can be seen from the above technical solution that the adjacent ends of the water inlet pipe and the acid outlet pipe are connected together in a sealed state. There is an acid inlet on the pipe wall of the water inlet pipe, and the acid inlet is connected to an acid inlet pipe that is vertical to the longitudinal direction of the water inlet pipe. There is a nozzle in the water inlet pipe before the acid inlet, and the front and rear ends of the nozzle are respectively the first circular tube section and the first conical section, and the outer circle of the first circular tube section is connected to the inner wall of the water inlet pipe in a sealed state, and the outer wall of the first conical section corresponds to the acid inlet. There is a mixing tube in the water inlet pipe after the acid inlet, and the front and rear ends of the mixing tube are respectively short tapered inlet and long tapered outlet with large outside and small inside, and the small end of the first tapered section of the nozzle is flush with the short tapered inlet of the mixing tube, and a spacing is left around the outer wall of the first tapered section of the nozzle and the short tapered inlet of the mixing tube.

[0011] During operation, tap water is sent into the water inlet pipe by a water pump, and then sprayed into the short conical inlet of the inner end of the mixing tube by the shower nozzle. Meanwhile, sulfate solution is sent into the acid inlet pipe by a water pump and flows into the first conical section of the shower nozzle. Under pressure, the sulfate solution flowing into the first conical section flows into the small end of the first conical section and the short conical inlet of the mixing tube, so that the sulfuric acid solution and tap water in the short conical inlet of the mixing tube are uniformly mixed, and then, after passing through the second circular tube section and the second conical section of the mixing tube, the sulfuric acid solution is discharged from the first acid outlet of the mixing tube and the second acid outlet of the acid outlet pipe successively. Compared with the preparation of the mechanical stirring device in the background technology, the preparation of sulfuric acid solution can be realized without the need of the mechanical stirring device, which reduces equipment investment and energy consumption and reduces production cost. Again, because the mechanical stirring device is not needed, it not only takes less time, has high production efficiency, but also can reach an ideal mixing effect, thereby ensuring the product quality of the amino acid compound fertilizer.

[0013] like Figure 1As shown, the tubular acid dispenser of the utility model includes a water inlet pipe 2 and an acid outlet pipe 6. The water inlet pipe 2 and the acid outlet pipe 6 are both coaxially arranged in a horizontal shape, and one end of them is connected together in a sealed state by means of a sealing ring 5. An acid inlet 4 is processed on the tube wall of the water inlet pipe 2, and the acid inlet 4 is connected to an acid inlet pipe 3 which is vertically perpendicular to the water inlet pipe 2. A nozzle is arranged in the water inlet pipe 2 before the acid inlet 4, and the front section and rear end of the nozzle are respectively a first circular tube section 92 and a first conical section 91. The outer circle of the first circular tube section 92 is connected to the inner wall of the water inlet pipe 2 in a sealed state, and the outer wall of the first conical section 91 corresponds to the acid inlet 4. A mixing tube is arranged in the water inlet pipe 2 after the acid inlet 4, and the front and rear ends of the mixing tube are respectively processed with a short conical inlet 83 and a long conical outlet 84 which are larger on the outside and smaller on the inside. The small end of the first conical section 91 of the nozzle is flush with the short conical inlet 83 of the mixing tube, and a distance is left between the outer wall of the first conical section 91 of the nozzle and the short conical inlet 83 of the mixing tube.

[0014] The mixing tube comprises a second circular tube section 82 and a second conical section 81 . The second circular tube section 82 is located between the sealing ring 5 and the acid inlet 4 , and the second conical section 81 is located in the acid outlet pipe 6 behind the sealing ring 5 .

[0015] For the convenience of connection, flanges 10 are connected at both ends of the water inlet pipe 2, both ends of the acid outlet pipe 6 and the outer end of the acid inlet pipe 3. The adjacent ends of the water inlet pipe 2 and the acid outlet pipe 6 are connected together by means of flanges 10, bolts and nuts. During operation, the water inlet 2 and the acid inlet pipe 3 are connected to the tap water pipe and the acid storage tank respectively by means of corresponding flanges 10, water pumps and valves.

[0017] During operation, tap water is pumped into the water inlet pipe 2 by a water pump, and then sprayed into the short conical inlet 83 at the inner end of the mixing tube by the nozzle. At the same time, the sulfate mother liquor is pumped into the acid inlet pipe 3 by a water pump and flows to the first conical section 91 of the nozzle. Under the action of pressure, the sulfate mother liquor flowing into the first conical section 91 flows to the small end of the first conical section 91 and the short conical inlet 83 of the mixing tube, so that the sulfuric acid solution and tap water entering the short conical inlet 83 of the mixing tube are evenly mixed, and then pass through the second circular pipe section 82 and the second conical section 81 of the mixing tube in turn, and are discharged from the first acid outlet 84 of the mixing tube and the second acid outlet 7 of the acid outlet pipe 6 in turn.
