Description

Technical Field

[0001] This invention relates to the field of gas equipment operation and maintenance technology, and in particular to a gas equipment sewage discharge and deodorization device. Background Technology

[0002] According to relevant national standards, odorants must be added to natural gas to ensure that a noticeable, pungent odor is detected in the event of a leak, alerting nearby people to the presence of escaping gas and prompting them to take necessary safety measures. Because natural gas contains trace amounts of water, oil, and solid impurities, these impurities often accumulate in gas equipment during long-term gas transmission and require periodic venting. During this venting process, a certain amount of natural gas is inevitably released, and the odorant added to the gas is also released into the atmosphere, causing some environmental pollution.

[0003] To address the aforementioned technical problems, existing technologies typically employ filtration equipment to adsorb odors from fuel gas. For example, odors are removed by arranging adsorbent materials such as activated carbon in the filtration equipment. However, in practical applications, existing filtration equipment is ineffective at removing odors from fuel gas because the contact area between the adsorbent materials such as activated carbon and the fuel gas is insufficient, only about 40%. This necessitates multi-stage filtration of the fuel gas to meet emission standards, resulting in low treatment efficiency and increased treatment costs.

[0004] Therefore, how to increase the contact area between the adsorption material and the gas and efficiently remove the odor of the gas from the impurities in the gas equipment is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a gas equipment sewage and odor removal device to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention provides a gas equipment wastewater and odor removal device, comprising: The pre-connected combined separator is connected to the drain pipe of the gas equipment and is used to separate gas impurities into gas and settled impurities. The adsorption mechanism has an adsorption chamber filled with adsorption particles. The adsorption chamber is connected to a pre-separation separator. The gas is transported from the pre-separation separator to the adsorption chamber and drives the adsorption particles to float up and down in the adsorption chamber. The adsorption particles adsorb odors in the gas.

[0007] Furthermore, the pre-combination separator includes: A cyclone separator has a tangential feed pipe connected to the exhaust pipe of a gas equipment. The cyclone separator is used to separate gas impurities into water-containing gas and settling impurities. The settling impurities settle to the bottom of the cyclone separator, while the water-containing gas flows upward. The demister is connected at its bottom to the top of the cyclone separator. Multiple corrugated plates are evenly spaced inside the demister, and airflow channels are formed between adjacent corrugated plates. Water-containing gas flows from the cyclone separator to the airflow channels. Mist droplets in the water-containing gas collide with the corrugated plates and flow along the surface of the corrugated plates to the bottom of the cyclone separator. The water-containing gas flows out of the airflow channels and becomes gas.

[0008] Furthermore, the bottom of the cyclone separator is connected to a drain pipe, and a drain valve is installed on the drain pipe; the top of the demister is connected to an exhaust pipe, which is connected to the adsorption chamber, and an exhaust valve is installed on the exhaust pipe.

[0009] Furthermore, the settled impurities are droplets and solid particles with a particle size greater than 10 μm, and the mist droplets are droplets with a particle size of 5-10 μm.

[0010] Furthermore, the adsorption mechanism includes: An intake pipe is connected to a pre-combination separator, and fuel gas is delivered from the pre-combination separator to the intake pipe. An intake valve is installed on the intake pipe. The housing has a base inside, and an air inlet chamber is formed through the upper and lower surfaces of the base. The air inlet chamber is connected to an air inlet pipe. An adsorption chamber is defined inside the housing and is connected to the air inlet chamber. A gas outlet is provided at the top of the housing and a gas outlet valve is provided at the gas outlet.

[0011] Furthermore, the adsorption mechanism also includes: A conical air distribution plate with its tip pointing downwards has its upper edge fixedly connected to a connecting plate. The connecting plate is fixedly mounted on the base. The conical air distribution plate is located in the air inlet chamber. The conical air distribution plate has multiple air holes through its upper and lower surfaces. One end of each air hole is connected to the air inlet chamber, and the other end corresponds to the adsorption chamber.

[0012] Furthermore, the adsorption mechanism also includes: Side plates are disposed on the connecting plate; The lower mesh plate is positioned above the conical air distribution plate, and its outer edge is fixedly connected to the side plate; A mesh plate is disposed above the lower mesh plate. The mesh plate and the side plate are connected by a flexible connector. The side plate, the flexible connector, the mesh plate and the lower mesh plate form an adsorption chamber. When the gas is blown from the vent to the lower mesh plate and enters the adsorption chamber, the gas drives the mesh plate to move upward and expand the volume of the adsorption chamber. At the same time, the gas drives the adsorption particles to float up and down in the adsorption chamber, and the adsorption particles adsorb the odor in the gas.

[0013] Furthermore, the adsorption mechanism also includes: The flexible support is connected at one end to the lower surface of the mesh board and at the other end to the connecting plate.

[0014] Furthermore, the adsorbent particles include alumina spherical particles and activated carbon columnar particles.

[0015] Furthermore, the side plate, lower mesh plate, and upper mesh plate are all made of stainless steel. The upper mesh plate and the side plate are connected by an electrostatic discharge chain, which is grounded. An explosion-suppressing mesh is provided between the upper mesh plate and the gas outlet.

[0016] Furthermore, a temperature sensor is installed near the lower mesh plate in the air intake chamber, and an emergency pipe is provided on the base to communicate with the air intake chamber and the outside. An emergency valve is installed on the emergency pipe.

[0017] The present invention discloses the following technical effects: 1. This invention utilizes a conical gas distribution plate to diffuse the gas along the conical surface in all directions, forming a 360° uniform wall-attached jet. When the jet flows through the gas holes, the throttling effect at the orifice increases the gas velocity and directs it towards the adsorption chamber. The gas velocity drives the mesh plate to move upward, expanding the volume of the adsorption chamber, while simultaneously driving the adsorbed particles to float up and down within the expanded chamber. The expansion of the adsorption chamber volume is determined by the gas velocity and flow rate; a higher gas velocity results in a larger increase in chamber volume, while a lower velocity results in a smaller increase. Therefore, the gas can remain in the adsorption chamber for a sufficient time, fully contacting the floating adsorbed particles and allowing the particles to adsorb odors. This increases the contact area between the adsorbed particles and the gas, efficiently removing odors from impurities in gas equipment.

[0018] 2. The pre-filter can separate gas impurities into gas and settled impurities, preventing excessive water content in the gas from clogging the adsorption material.

[0019] 3. The design of elastic support pillars and flexible connectors allows the adsorption chamber to dynamically adjust its volume according to the gas flow rate, expanding the applicability of the equipment and ensuring that the adsorption particles are always in full contact with the gas and adsorb odors.

[0020] 4. This invention has good safety features and can avoid the risks of static electricity accumulation and explosion. Attached Figure Description

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 4 As shown, an embodiment of the present invention provides a gas equipment sewage and deodorization device, comprising: The pre-connected combined separator 1 is connected to the gas equipment drain pipe 105 and is used to separate gas impurities into gas and settled impurities. The adsorption mechanism 2 has an adsorption chamber 201, which is filled with adsorption particles 3. The adsorption chamber 201 is connected to the pre-separator 1. The gas is transported from the pre-separator 1 to the adsorption chamber 201 and drives the adsorption particles 3 to float up and down in the adsorption chamber 201. The adsorption particles 3 adsorb the odor in the gas.

[0027] In this embodiment, the pre-combination separator 1 includes: Cyclone separator 101 has a tangential feed pipe 102, which is connected to the gas equipment drain pipe 105. Cyclone separator 101 is used to separate gas impurities into water-containing gas and settling impurities. The settling impurities settle to the bottom of cyclone separator 101, and the water-containing gas flows upward. The bottom of the demister 103 is connected to the top of the cyclone separator 101. Multiple corrugated plates 104 are evenly spaced inside the demister 103. Adjacent corrugated plates 104 form an airflow channel. Water-containing gas flows from the cyclone separator 101 to the airflow channel. The mist droplets in the water-containing gas collide with the corrugated plates 104 and flow along the surface of the corrugated plates 104 to the bottom of the cyclone separator 101. After flowing out of the airflow channel, the water-containing gas becomes gas.

[0028] In this embodiment, the bottom of the cyclone separator 101 is connected to a drain pipe 105, and a drain valve is provided on the drain pipe 105; the top of the demister 103 is connected to an exhaust pipe 106, which is connected to the adsorption chamber 201, and an exhaust valve is provided on the exhaust pipe 106.

[0029] In this embodiment, the sedimented impurities are droplets and solid particles with a particle size greater than 10 μm, and the mist droplets are droplets with a particle size of 5-10 μm.

[0030] In this embodiment, the cyclone separator 101 can be made using existing technology, which can separate settled impurities and water-containing gas through centrifugal rotation.

[0031] In this embodiment, the adsorption mechanism 2 includes: The intake pipe 202 is connected to the pre-combination separator 1. Gas is delivered from the pre-combination separator 1 to the intake pipe 202. An intake valve is installed on the intake pipe 202. The housing 203 has a base 204 inside it. The base 204 has an air inlet chamber 205 through its upper and lower surfaces. The air inlet chamber 205 is connected to the air inlet pipe 202. An adsorption chamber 201 is defined inside the housing 203. The adsorption chamber 201 is connected to the air inlet chamber 205. A gas outlet 206 is provided at the top of the housing 203. The gas outlet 206 is equipped with an air outlet valve.

[0032] In this embodiment, the adsorption mechanism 2 further includes: The conical air distribution plate 207 has its tip pointing downwards and its upper edge fixedly connected to the connecting plate 209. The connecting plate 209 is fixedly mounted on the base 204. The conical air distribution plate 207 is located inside the air inlet chamber 205. The conical air distribution plate 207 has multiple air holes 2071 extending through its upper and lower surfaces. One end of the air hole 2071 is connected to the air inlet chamber 205, and the other end corresponds to the adsorption chamber 201.

[0033] In this embodiment, the adsorption mechanism 2 further includes: Side plate 208 is mounted on connecting plate 209; The lower mesh plate 2010 is positioned above the conical air distribution plate 207, and its outer edge is fixedly connected to the side plate 208. The top plate 2012 is positioned above the bottom plate 2010. The top plate 2012 and the side plate 208 are connected by a flexible connector 2011. The side plate 208, the flexible connector 2011, the top plate 2012 and the bottom plate 2010 form an adsorption chamber 201. When the gas is blown from the vent 2071 to the lower mesh plate 2010 and enters the adsorption chamber 201, the gas drives the upper mesh plate 2012 to move upward and expand the volume of the adsorption chamber 201. At the same time, the gas drives the adsorption particles 3 to float up and down in the adsorption chamber 201, and the adsorption particles 3 adsorb the odor in the gas.

[0034] In this embodiment, the flexible connecting plate 209 can be made of an elastic material, such as insulating rubber, etc.

[0035] In this embodiment, the adsorption mechanism 2 further includes: The elastic support 2013 is connected at one end to the lower surface of the mesh plate 2012 and at the other end to the connecting plate 209. The elastic support 2013 has an elastic tendency to pull the mesh plate 2012 downward. Its elastic force should not be set too large in order to reduce the minimum flow rate requirement of the gas.

[0036] In this embodiment, the adsorption particles 3 include alumina spherical particles and activated carbon columnar particles. Activated carbon is the primary adsorption material, and alumina is the auxiliary adsorption material. Alumina has excellent hydrophilicity; although over 99% of the moisture in the fuel gas has been removed in the pre-separator 1, long-term use will still lead to the activated carbon absorbing a large amount of water, causing micropore blockage. Therefore, this embodiment uses alumina to adsorb water vapor, and alumina has a higher adsorption priority for water vapor than fuel gas. Furthermore, alumina has a higher density than activated carbon. During the up-and-down movement of the adsorption particles 3 driven by the fuel gas, alumina can naturally settle to the bottom of the adsorption chamber 201, forming a high-density zone, inhibiting excessive blowing of activated carbon by the fuel gas, and ensuring the adsorption effect of activated carbon. Moreover, the alumina settling to the bottom of the adsorption chamber 201 allows it to contact the fuel gas first and absorb residual moisture, further preventing micropore blockage of the activated carbon. The total volume of the adsorption particles 3 arranged in the adsorption chamber 201 should be less than the volume of the adsorption chamber 201 expanded after the flexible connector 2011 is straightened. The specific arrangement volume of the adsorption particles 3 can be flexibly adjusted according to the actual situation.

[0037] In this embodiment, the side plate 208, the lower mesh plate 2010, and the upper mesh plate 2012 are all made of stainless steel. The upper mesh plate 2012 and the side plate 208 are connected by an electrostatic discharge chain, which is grounded. An explosion-suppressing mesh is provided between the upper mesh plate 2012 and the gas outlet 206. The explosion-suppressing mesh has a through-hole structure that extends through the upper and lower surfaces, allowing the gas to flow upwards. The explosion-suppressing mesh is made of flame-retardant and explosion-proof materials, which can prevent explosions in the event of accidental ignition of the gas.

[0038] In this embodiment, a temperature sensor 2014 is installed in the air intake chamber 205 near the lower mesh plate 2010. An emergency pipe 2015, communicating with the air intake chamber 205 and the outside, is provided on the base 204. An emergency valve is installed on the emergency pipe 2015. In the event of an accidental gas fire, the temperature sensor 2014 can quickly detect a sudden increase in temperature. At this time, the emergency valve can be opened to quickly discharge the gas in the air intake chamber 205 through the emergency pipe 2015, and the air intake valve can also be closed, etc.

[0039] The specific work process is as follows: S1: When the gas equipment discharges waste gas, gas impurities enter the cyclone separator 101 through the gas equipment drain pipe 105 and the tangential feed pipe 102. The gas impurities are separated into water-containing gas and settling impurities by centrifugal rotation. The settling impurities settle to the bottom of the cyclone separator 101, while the water-containing gas flows upward. S2: Water-containing gas flows upward from the cyclone separator 101 to the airflow channel, where it undergoes a sawtooth-shaped tortuous motion. This causes the droplets in the water-containing gas to collide with the corrugated plate 104 and flow along the surface of the corrugated plate 104 to the bottom of the cyclone separator 101. After flowing out of the airflow channel, the water-containing gas becomes gas. The bottom of the cyclone separator 101 is connected to a drain pipe 105, which is equipped with a drain valve. The drain valve is opened periodically to discharge the settled impurities at the bottom of the cyclone separator 101. S3: The gas enters the intake chamber 205 through the exhaust pipe 106 and the intake pipe 202, and quickly impacts the tip of the conical air distribution plate 207. It then spreads outwards along the conical surface, forming a 360° uniform wall-attached jet. When the jet flows through the air holes 2071, the throttling effect at the orifices increases the gas velocity and directs it towards the adsorption chamber 201. The gas velocity drives the mesh plate 2012 upwards, expanding the volume of the adsorption chamber 201. Simultaneously, it drives the adsorption particles 3 to float up and down within the expanded adsorption chamber 201. Overall, all the adsorption particles 3 are in a state of disordered movement, allowing the gas to remain in the adsorption chamber 201 for a sufficient time, fully contacting the floating adsorption particles 3 and allowing the adsorption particles 3 to adsorb the odor. It should be noted that the gas velocity must be controlled within a certain range; it should not be too high or too low. While an excessively high gas velocity will cause the adsorption particles 3 in the adsorption chamber 201 to float up and down at high speed, it also poses a risk of "airflow short circuit," meaning the gas velocity is too fast and the odor is not fully adsorbed. If the gas flow rate is too low, the distance between the adsorption particles 3 floating up and down will be insufficient, which will not significantly increase the contact area between the adsorption particles 3 and the gas. Therefore, the specific gas flow rate should be flexibly set according to the actual situation in order to fully adsorb the odor of the gas.

[0040] S4: The gas that has absorbed the odor passes through the explosion suppression grid and is discharged from the gas outlet 206.
