Description

Technical Field

[0001] This utility model relates to the field of wastewater ammonia removal technology, and in particular to an anti-clogging ammonia removal tower tray. Background Technology

[0002] There are two relatively mature existing ammonia removal processes: the sodium method and the calcium method. The sodium method involves adding sodium hydroxide to the feedstock to adjust the pH before it enters the ammonia removal tower to recover the ammonia gas from the top. The high-salt wastewater formed at the bottom of the tower, containing substances such as sodium chloride and sodium sulfate, then enters the subsequent evaporation treatment process. This process route results in a relatively high solubility of inorganic salts in the bottom liquid, making the ammonia removal tower less prone to clogging. However, the cost of the reagent (sodium hydroxide) is relatively high. The calcium method involves adding calcium hydroxide or calcium oxide to the feedstock to adjust the pH before it enters the ammonia removal tower to recover the ammonia gas from the top. The high-salt wastewater formed at the bottom of the tower, containing substances such as calcium hydroxide and calcium sulfate, then enters the subsequent evaporation treatment process. This process route results in a relatively low solubility of inorganic salts in the bottom liquid, making the ammonia removal tower more prone to clogging. However, the cost of the reagent (calcium hydroxide or calcium oxide) is relatively low.

[0003] In the calcium-based ammonia removal process, existing ammonia removal towers all use traditional trays, such as plate-type and solid-valve-type trays. Because the ammonia removal process generates components with low solubility, such as calcium hydroxide and calcium sulfate, and because existing trays need to maintain a certain liquid level for gas-liquid contact, the resulting solids easily deposit and clog the trays. Therefore, we propose an anti-clogging ammonia removal tower tray. Utility Model Content

[0004] This invention proposes an anti-clogging ammonia removal tower tray, which solves the existing problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-clogging ammonia removal tower tray, comprising an ammonia removal tower, wherein several layers of fixed frames are arranged inside the ammonia removal tower, and a connecting frame is connected to the top of the fixed frames. A tower tray is connected to the top of the connecting frame, and multiple sets of empty slots are opened inside the tower tray. A crossbeam is arranged inside the multiple sets of empty slots, and a distributor is connected to the bottom of the crossbeam. The distributor has multiple sets of second distribution holes. A first distribution hole is opened inside the crossbeam. A fixed column is connected to the top of the crossbeam, and multiple sets of first guide plates are arranged on the outside of the fixed column. The guiding direction of the first guide plates corresponds to the structure of the distributor. A surrounding second guide plate is arranged inside the empty slot.

[0006] Preferably, the fixing frame is provided with multiple sets of first slots, and each set of first slots is provided with a spring fixing pin, and a spring is connected to the outside of the spring fixing pin.

[0007] Preferably, the bottom of the connecting frame is provided with a connecting column, the connecting column is engaged with the spring fixing pin to form a reset lifting structure, and the top of the connecting column is provided with a limit post.

[0008] Preferably, a limiting groove is provided at the bottom of the tray, and the limiting groove engages with a limiting post to form a limiting structure.

[0009] Preferably, a water collection tank is connected to the bottom of the deammoniation tower, and a steam engine is installed at the top of the water collection tank. A steam pipe is installed at the top of the steam engine, and the steam pipe is connected through to the inside of the deammoniation tower.

[0010] Preferably, the outside of the ammonia removal tower is provided with a water inlet mechanism and an ammonia condensation mechanism. The water inlet mechanism includes a water pump, one end of which is connected to the water inlet of the ammonia removal tower, and the other end of which is connected to a water inlet pipe. The other end of the water inlet pipe is connected to a water tank.

[0011] Preferably, the ammonia condensation mechanism includes a condenser, with one side of the condenser corresponding to the exhaust port of the ammonia removal tower, and the other side of the condenser connected to a drain pipe, with the other end of the drain pipe connected to an ammonia water tank.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The distributor adopts a honeycomb porous plate structure. The liquid is sprayed into a fine stream through the porous plate, while the airflow at the bottom is sprayed out in the opposite direction from the spray hole, forming a high-speed gas-liquid mixed jet. This jet washes the surface of the tray and the distribution channel in a turbulent state, which can effectively remove the attached solid particles such as calcium hydroxide and calcium sulfate, and avoid deposition and blockage.

[0014] 2. By setting the first guide plate to accelerate the water flow speed and precisely guide the water flow direction, the liquid is made into a directional jet to wash the surface of the tray and prevent solid particles from depositing.

[0015] 3. The tray can be quickly assembled and disassembled by the limiting posts and the limiting grooves below the tray. The spring-driven reset and lifting structure, along with the pressure of the water flow, allows the connecting frame to continuously lift and lower the tray during operation, thereby preventing solid particles from settling.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-8This utility model provides a technical solution: an anti-clogging ammonia removal tower tray, including an ammonia removal tower 1. The ammonia removal tower 1 has several layers of fixed frames 2 inside, and a connecting frame 3 is connected to the top of the fixed frames 2. A tower tray 4 is connected to the top of the connecting frame 3. The tower tray 4 has multiple sets of empty slots 401 inside, and a crossbeam 5 is arranged inside the multiple sets of empty slots 401. A distributor 6 is connected to the bottom of the crossbeam 5, and the distributor 6 has multiple sets of second distribution holes 7. A first distribution hole 501 is opened inside the crossbeam 5, and a fixed column 8 is connected to the top of the crossbeam 5. Multiple sets of first guide plates 9 are arranged on the outside of the fixed column 8. The first guide plate 9 has a guiding direction corresponding to the distributor 6. A second guide plate 10 is arranged around the inside of the empty trough 401. A water inlet mechanism and an ammonia condensation mechanism are arranged on the outside of the deammoniation tower 1. A water collection tank 11 is connected to the bottom of the deammoniation tower 1, and a steam engine 12 is arranged at the top of the water collection tank 11. A steam pipe 13 is arranged at the top of the steam engine 12, and the steam pipe 13 is connected through to the inside of the deammoniation tower 1. The water inlet mechanism includes a water pump 14, and one end of the water pump 14 is connected to the water inlet of the deammoniation tower 1. The other side of the water pump 14 is connected to a water inlet pipe 15, and the other end of the water inlet pipe 15 is connected to a water tank 16.

[0027] In practice, water pump 14 is started, and wastewater in water tank 16 is pumped into the top of ammonia removal tower 1 through inlet pipe 15. The wastewater flows down to tray 4 along the inlet. As the wastewater passes through the empty slot 401 of tray 4, the second distribution hole 7 of distributor 6 forms a fine stream, evenly distributing it to the area below the tray. There is a certain distance between distributor 6 and the second guide plate 10, allowing the water to flow downwards from the outside of distributor 6. Steam generator 12 in water collection tank 11 is started, and steam is introduced into the tower through steam pipe 13, heating the wastewater to 50-70℃, increasing the solubility of inorganic salts, and simultaneously promoting the volatilization of ammonia nitrogen to form ammonia gas. During the upward flow of ammonia gas, it fully contacts the wastewater below tray 4 through the gas-liquid mixing zone formed by distributor 6, causing ammonia nitrogen to transfer from the liquid phase to the liquid phase. The liquid is moved to the gas phase to complete the ammonia removal process. The first guide plate 9 guides the liquid to form a directional jet, which washes the surface of the tray 4 and the two sets of distribution holes. As the water flows downward, the pressure of the water flow causes the tray 4 to exert pressure on the connecting frame 3 below, which in turn causes the connecting frame 3 to exert pressure on the spring 203, thereby driving the tray 4 to descend. Because the water flows downward, it has to pass through multiple sets of distribution holes, and the water flow is inconsistent, so the spring 203 is subjected to less pressure and thus resets. Through the design of the reset structure, the tray 4 continuously moves up and down, thereby preventing solid particles from depositing around the distributor 6. Through the design of the multi-layer tray 4, the ammonia nitrogen collected in the wastewater can be fully deaminated and finally flows to the collection tank 11 below.

[0028] Reference Figure 6 and Figure 7The fixing frame 2 has multiple sets of first slots 201 inside, and each set of first slots 201 has a spring fixing pin 202 inside. A spring 203 is connected to the outside of the spring fixing pin 202. The bottom of the connecting frame 3 has a connecting post 301. The bottom of the connecting post 301 has a connecting hole that matches and engages with the spring fixing pin 202. The connecting post 301 and the spring fixing pin 202 are engaged to form a reset lifting structure. The top of the connecting post 301 has a limit post 302. The bottom of the tower tray 4 has a limit groove 402, and the limit groove 402 engages with the limit post 302 to form a limit structure. In specific implementation, when installing the tower tray, it is only necessary to engage the limit groove 402 at the bottom of the tower tray 4 with the connecting post 301 at the top of the connecting frame 3 to achieve quick disassembly and installation of the tower tray 4.

[0029] Reference Figure 2 The ammonia condensation mechanism includes a condenser 17, with one side of the condenser 17 corresponding to the exhaust port of the ammonia removal tower 1, and the other side of the condenser 17 connected to a drain pipe 18, with the other end of the drain pipe 18 connected to an ammonia water tank 19. In specific implementation, in order to prevent ammonia from being directly discharged and causing air pollution, the ammonia discharged from the top of the ammonia removal tower 1 enters the condenser 17, and after being condensed and liquefied, it forms ammonia water, which is collected in the ammonia water tank 19 through the drain pipe 18 for subsequent processing.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
