Description

Technical Field

[0001] This application relates to the technical field of waste gas treatment, and particularly relates to a waste gas treatment box. Background Art

[0002] At present, a large amount of tail gas is emitted during the operation of a diesel engine. In response to the call for environmental protection and energy conservation, a waste gas treatment device is usually installed at the tail of the exhaust pipe of the diesel engine to achieve tail gas cooling, absorb some pollutants, and reduce emissions.

[0003] In the prior art, the waste gas treatment device mostly adopts the form of a water tank. The water tank is filled with water, and the exhaust pipe of the diesel engine is directly inserted into the water. When the tail gas is emitted, it contacts the water, and the water is used to purify and cool the tail gas.

[0004] However, due to the relatively fast exhaust gas emission speed, a large number of relatively large bubbles will be formed in the water tank. This easily leads to uneven contact between the exhaust gas and the cooling water, affecting the purification and cooling effects. At the same time, the large bubbles are likely to cause water splashing when breaking through the water surface, which not only pollutes the working environment but also causes waste of water resources, and is very inconvenient.

[0005] In view of the above problems, a waste gas treatment box is designed now. Summary of the Utility Model

[0006] The embodiments of this application provide a waste gas treatment box to solve the problems in the related art that when a general waste gas treatment device treats the tail gas of a diesel engine, the contact between the tail gas and the cooling water is uneven, which will affect the purification and cooling effects, and at the same time, water splashing is likely to occur during use, making it inconvenient to use.

[0007] In a first aspect, a waste gas treatment box is provided, which includes:

[0008] A box body, an air outlet is provided at the upper end of the box body, and a float chamber communicating with the inside of the box body is provided inside the box body;

[0009] A water inlet pipe, which is provided on the box body;

[0011] An air inlet pipe, which is fixedly arranged inside the box body, an air inlet is provided at the upper end of the air inlet pipe, and an exhaust port is provided at the lower end of the air inlet pipe;

[0012] A plurality of shunt pipes, several groups of the shunt pipes are provided inside the box body, the upper ends of the shunt pipes are communicated with the air inlet pipe, and the lower ends of the shunt pipes correspond to the exhaust port.

[0013] In some embodiments, a sieve plate is provided inside the box body. The sieve plate is sleeved on the water inlet pipe and several shunt pipes, and the sieve plate is located above the exhaust port.

[0014] In some embodiments, several of the shunt pipes are evenly distributed in a ring around the periphery of the intake pipe.

[0015] In some embodiments, the shunt pipe includes a connecting pipe and an exhaust pipe. The connecting pipe is inclined. The upper end of the connecting pipe is provided on the intake pipe and is communicated with it. The exhaust pipe is provided at the lower end of the connecting pipe, and the exhaust pipe is parallel to the intake pipe.

[0016] In some embodiments, several separation plates are provided inside the box body. The several separation plates are inclined, and the several separation plates are located between the intake pipe and the air outlet.

[0017] In some embodiments, several baffle plates are provided inside the air outlet, and the baffle plates are inclined.

[0018] The embodiment of the present application provides an exhaust gas treatment box. The present application can slow down and shunt the tail gas by setting a sieve plate and several shunt pipes, thereby dispersing the tail gas, increasing the contact time between the tail gas and the cooling water, and enabling the tail gas to contact the cooling water more evenly and fully. In this way, the purification and cooling effects of the tail gas can be ensured. At the same time, the volume of the bubbles is reduced, and the splashing of the cooling water with the bubbles can be avoided. By setting a plurality of separation plates and baffle plates, the cooling water can also be blocked and recycled, which can not only ensure the working environment but also avoid the waste of water resources, and has strong practicability.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some, rather than all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0024] The embodiments of this application provide an exhaust gas treatment box, which can solve the problems in the related art that when a general exhaust gas treatment device treats the exhaust gas of a diesel engine, the exhaust gas is unevenly in contact with the cooling water, which will affect the purification and cooling effects. At the same time, water splashing is likely to occur during use, making it inconvenient to use.

[0025] Please refer to Figure 1 - Figure 2 , an exhaust gas treatment box, which includes: a box body 1, a water inlet pipe 2, a float valve assembly 3, an air inlet pipe 4, and several shunt pipes 5. An air outlet 11 is provided at the upper end of the box body 1. A float chamber 12 communicating with the inside of the box body 1 is provided inside the box body 1. The water inlet pipe 2 is provided on the box body 1. The float valve assembly 3 is provided inside the box body 1 and connected to the water inlet pipe 2. The float valve assembly 3 is located inside the float chamber 12;

[0026] The water inlet pipe 2 is connected to the box body 1 through a flange. One end of the water inlet pipe 2 close to the box body 1 extends into the box body 1 and is connected and fixed to the float valve assembly 3 through a thread. In this way, when the flange is removed from the box body 1, the water inlet pipe 2 and the float valve assembly 3 can be taken out of the box body 1 for easy replacement and adjustment;

[0027] In this way, water can be supplied into the box body 1 through the water inlet pipe 2, and at the same time, the water level in the box body 1 can be controlled through the float valve assembly 3, so that the water level in the box body 1 always remains at a set position, enabling the box body 1 to achieve automatic water supply;

[0028] It should be noted that the float valve assembly 3 in this application is a prior art and is a device that can be purchased on the market. Controlling the water level through a float valve is also a prior art. At the same time, this application does not improve the float valve itself, so no more description will be given;

[0029] The air inlet pipe 4 is fixedly arranged inside the box body 1. An air inlet 41 is provided at the upper end of the air inlet pipe 4. An exhaust port 42 is provided at the lower end of the air inlet pipe 4. Several of the shunt pipes 5 are all arranged inside the box body 1. The upper end of the shunt pipe 5 is communicated with the air inlet pipe 4. The lower end of the shunt pipe 5 corresponds to the exhaust port 42;

[0030] When it is necessary to purify and cool the exhaust gas of a diesel engine, the exhaust gas can be discharged into the intake pipe 4 through the intake port 41, so that the exhaust gas is discharged into the purified water in the box body 1 through the exhaust port 42. At the same time, part of the exhaust gas will enter into a plurality of shunt pipes 5 and finally be discharged from the lower ends of the plurality of shunt pipes 5. In this way, the exhaust gas can be brought into contact with the purified water, so that the exhaust gas can be cooled by the purified water. At the same time, some pollutants such as soot, NOx, and sulfides in the exhaust gas can be adsorbed. Then, the gas after purification and cooling is discharged outwards through the air outlet 11.

[0031] By arranging a plurality of shunt pipes 5 in this way, not only can the flow rate of the exhaust gas be slowed down, the contact time between the exhaust gas and the cooling water be increased, but also the exhaust gas can be shunted to prevent large bubbles from being generated when the exhaust gas directly enters the water through the intake pipe 4. In this way, the volume of the bubbles can be reduced, and the large bubbles can be dispersed into a plurality of small bubbles, so that the exhaust gas can be in more uniform and sufficient contact with the cooling water. In this way, the purification and cooling effects on the exhaust gas can be ensured. At the same time, the volume of the bubbles is reduced, and the cooling water can be prevented from splashing everywhere along with the bubbles. This can not only ensure the working environment, but also avoid waste of water resources. In this way, the device can better purify and cool the exhaust gas even when the cooling water is at a limited level, so that the volume of the box body 1 can be reduced for easy installation and use, and it has strong practicability.

[0032] At the same time, by placing the float valve assembly 3 in the float chamber 12, the float valve assembly 3 can also be separated from the exhaust gas, so as to prevent the float from moving when the bubbles float up, affecting the use effect and service life of the float valve.

[0033] Specifically, in this embodiment, a sieve plate 6 is provided in the box body 1. The sieve plate 6 is sleeved on the intake pipe 2 and a plurality of shunt pipes 5, and the sieve plate 6 is located above the exhaust port 42.

[0034] When the exhaust gas is discharged outwards through the exhaust port 42 and the shunt pipes 5 and comes into contact with the cooling water to form bubbles, the bubbles will come into contact with the sieve plate 6 during the upward floating process. In this way, the bubbles can be broken up by the sieve plate 6. Not only can the bubbles be broken up into more small bubbles, enabling the exhaust gas to better and more fully and evenly contact with the cooling water, thus ensuring the purification and cooling effects on the exhaust gas, but also it can further prevent the cooling water from splashing due to the bursting of large bubbles when they float to the water surface. In this way, the splashing range of the cooling water can be further reduced, facilitating use.

[0035] More specifically, a plurality of the shunt pipes 5 are evenly distributed in a ring around the periphery of the intake pipe 4.

[0036] This enables the exhaust gas to come into uniform contact with the cooling water at different positions inside the box body 1, so that the cooling water at different positions can be fully utilized, further ensuring the purification and cooling effect on the exhaust gas, with strong practicability.

[0037] Furthermore, in this embodiment, the shunt pipe 5 includes a connecting pipe 51 and an exhaust pipe 52. The connecting pipe 51 is inclined. The upper end of the connecting pipe 51 is arranged on the intake pipe 4 and is communicated with it. The exhaust pipe 52 is arranged at the lower end of the connecting pipe 51, and the exhaust pipe 52 is parallel to the intake pipe 4.

[0038] In this way, through the bent shunt pipe 5, when the exhaust gas enters the exhaust pipe 52 through the connecting pipe 51, the bent shunt pipe 5 can block and buffer the exhaust gas, thereby reducing the flow rate of the exhaust gas when it is discharged, so that the exhaust gas can be in contact with the cooling water for a longer time, further ensuring the purification and cooling effect on the exhaust gas, with strong practicability.

[0039] Among them, a number of separation plates 7 are arranged inside the box body 1. The a number of separation plates 7 are inclined. The a number of separation plates 7 are located between the intake pipe 4 and the air outlet 11.

[0040] In this way, when the bubbles generated by the exhaust gas carry the cooling water and splash, the splashing cooling water can be blocked by the multiple separation plates 7, so that the purified air flows out through the gaps between the separation plates 7. At the same time, the cooling water remaining on the separation plates 7 will fall by gravity for recycling, so that the splashing of water can be reduced, not only ensuring the cleanliness of the working environment, but also avoiding the waste of water resources.

[0041] And when the water splashes on the separation plates 7, some water mist will be formed, so that the water mist can be further in full contact with the exhaust gas, further enhancing the purification and cooling effect on the exhaust gas and facilitating the use.

[0042] Even further, a number of baffle plates 8 are arranged inside the air outlet 11, and the baffle plates 8 are inclined.

[0043] In this way, after the exhaust gas flows out through the gaps between the separation plates 7, the exhaust gas will move mixed with the water mist. At the same time, the saturated steam in the water mist will continuously collide and condense into large water droplets during the movement and settle to the shallow water layer at the bottom of the box body 1 for circulation. Finally, the low-temperature exhaust gas moves upward and is discharged through the air outlet 11. At the same time, part of the exhaust gas and some water mist will be blocked by the baffle plates 8 during the discharge process, so that some water mist will adhere to the baffle plates 8. When there is more water mist on the baffle plates 8, it will condense into water droplets and fall into the box body 1 for recycling, further reducing the waste of water resources discharged from the box body 1, with strong practicability.
