Description

Technical Field

[0001] The utility model relates to the field of environmental protection equipment, and particularly relates to a steam-water separator. Background Art

[0002] The steam-water separator is an essential equipment in the remediation of soil and groundwater. The steam-water separator is installed on the DPE waste gas treatment equipment to separate steam and water from the polluted water-containing gas, and then the polluted gas enters the activated carbon box and is discharged up to the standard after adsorption again. At present, the steam-water separators on the market can only separate water droplets larger than 200 microns at a gas flow rate of 40 - 50 °C and 200 - 400 m 3 / h. However, the gas treatment equipment requires that the water droplets entering the activated carbon box should be below 200 microns. For the original steam-water separator of the equipment, a condenser needs to be installed, which increases the floor area of the equipment. Due to temperature reasons, the steam-water separation effect is poor, and the service life of the activated carbon is shortened, resulting in non-compliance of waste gas treatment and inability to meet the requirements of soil remediation.

[0003] Therefore, in view of the above problems, the utility model provides a steam-water separator suitable for steam-water separation in the field of soil remediation. Summary of the Invention

[0004] (I) Technical Problems to be Solved

[0005] For this reason, the utility model provides a steam-water separator, which mainly solves the problem that the existing steam-water separator cannot meet the requirement of separating particulate water mist below 20 - 200 microns at a temperature of 40 - 50 °C, a flow rate of 200 - 400 m 3 / h without installing a condenser.

[0006] (II) Technical Solutions

[0007] To achieve the above object, the utility model provides the following technical solutions: A steam-water separator includes a steam-water separation tank body and an internal filter element. The upper cover of the tank body is fixed by bolts, a welded air outlet is arranged on the outer side of the upper edge, an air inlet is arranged at the center of the upper cover, flanges are fixedly arranged at one ends of the air outlet and the air inlet, an air inlet pipe is connected below the air inlet, and a drain port is arranged on the outer side of the tank body. The filter element includes an air inlet pipe, a conical guide umbrella, a first filter layer, and second and third filter layers.

[0008] Preferably, the upper part of the air inlet pipe is connected to the air inlet, and the lower part is spliced with a fixed seat in the tank body. A total of 4 layers of adjacent circular small air holes of the same size are opened around the air inlet pipe from top to bottom, and the total area of all small air holes is smaller than the area of the air inlet.

[0009] Preferably, the conical guide umbrella is welded to the air inlet pipe in four layers corresponding to the air holes opened on the air inlet pipe, and the air holes are aligned with the upper one-third inside the guide umbrella.

[0010] Preferably, the first filter layer is arranged inside the conical diversion umbrella, and a 40-mm-thick filter cotton is arranged below the air holes and supported by 6 stainless steel branch pipes welded inside the diversion umbrella to filter and adsorb water vapor.

[0011] Preferably, the second and third filter layers are cylindrical and arranged outside the diversion umbrella, and are composed of an inner stainless steel fixing net, a 40-mm-thick medium-density filter cotton plus an intermediate layer stainless steel fixing net and a second layer of 10-mm-high-density filter cotton plus an outer layer stainless steel fixing net, and are fixed by an upper cover and a lower cover of the filter layer to filter and adsorb the remaining water vapor.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the steam-water separator provided by the utility model has the following beneficial effects:

[0014] This separation device has been manufactured and put into actual projects for use. After on-site inspection, the device has achieved the separation of 20-200 micron-sized water mist particles at a temperature of 40-50°C without installing a condenser. Compared with traditional separation devices, which require the installation of a condenser and can only separate water mist particles larger than 200 microns, it saves more costs and reduces the floor area.

[0015] This device consists of an external tank body and an internal filter element, with a simple structure, convenient for disassembly and assembly. The filtration method adopts a combination of horizontal and vertical methods to achieve a double-effect filtration effect.

[0016] This device uses a dual separation of a conical diversion umbrella and a filter layer in cooperation. After the gas enters the device, its flow rate slows down and it collides and aggregates through the conical diversion umbrella for primary gas-liquid separation. Then, it undergoes secondary gas-liquid separation through the first filter layer and leaves the conical diversion umbrella. The gas passes through the second and third filter layers for tertiary gas-liquid separation and is discharged from the air outlet, improving the separation efficiency. Compared with traditional devices, the water droplet diameter that can be separated is smaller and the gas-liquid separation is more thorough.

[0017] The upper cover of the filter layer of this device is welded to the intake pipe, the lower cover of the filter layer uses bolt connection, and the second and third filter layers are fixed into a cylindrical shape by stainless steel fixing nets and installed between the upper cover and the lower cover of the filter layer. The filter cotton is convenient to replace and saves manpower.

[0018] For the steam-water separation in the remediation of contaminated soil, compared with traditional steam-water separation devices, this device, without installing a condenser, performs double steam-water separation treatment through a conical diversion umbrella and a filter layer, and has a good steam-water separation effect. It improves the effect of the gas entering the activated carbon adsorption after gas-liquid separation, extends the service life of the activated carbon, and ensures the soil remediation effect.

[0019] In this separation device, after gas-liquid separation, the liquid drips along the conical diversion umbrella onto the lower cover of the filter layer. The lower cover of the filter layer is provided with water outlet holes, and the liquid flows through the water outlet holes to the bottom of the tank body. A drain port is provided at the bottom of the tank to discharge the liquid in time, so that the separated liquid is not entrained again, ensuring the gas-liquid separation effect.

[0020] In this separation and steam-water separation device, after the liquid condenses, it accumulates at the bottom of the tank and is discharged through the drain port welded on the outer side of the tank body and enters the wastewater treatment system; the waste gas is discharged through the air outlet welded on the outer side of the upper part of the tank body and enters the waste gas treatment equipment; both the separated gas and water phases are convenient for collection and treatment and will not cause secondary pollution.

[0021] This separation device is equipped with multiple layers of filter cotton, which can adsorb other components in the gas while adsorbing water vapor, not only achieving high-efficiency steam-water separation but also having a primary effect of waste gas adsorption.

[0022] This device is made of stainless steel, has good corrosion resistance, and can adapt to various environmental conditions. In actual application, the device is in a coastal climate and can be used normally and has a good separation effect in extreme environments with high temperature, high humidity, and high salt content.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of the present utility model.

[0033] In the description of the present utility model: unless otherwise specified, the meaning of "a plurality" is two or more. "First", "second", "third", etc. are intended to distinguish the referred objects and do not have special significance in terms of technical connotation and should not be understood as emphasizing the degree of importance or order, etc.

[0034] In the description of the embodiments of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the embodiments of the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present utility model.

[0035] As Figure 2 shown, for the steam-water separator applicable to the field of soil remediation, the tank body 1 and the tank body upper cover 2 are bolted; the air inlet 3 is welded at the center of the tank body upper cover 2.

[0036] The air outlet 4 is welded on the upper outer side of the tank body 1, the drain port 5 is welded on the lower outer side of the tank body 1, and the intake pipe fixing seat 10 is welded at the center of the inner side of the bottom of the tank body 1.

[0037] The upper end of the intake pipe 6 is connected to the air inlet 3, and the lower end is connected to the intake pipe fixing seat 10. The upper filter layer cover 7 is welded to the upper part of the intake pipe 6, and the lower filter layer cover 9 is bolted to the lower part of the intake pipe 6. A total of 4 conical flow guiding umbrellas 8 are welded to the intake pipe 6 from top to bottom between the upper filter layer cover 7 and the lower filter layer cover 9.

[0038] 6 stainless steel branch pipes 101 are arranged at each place, and are welded to the outside of the intake pipe 6 in a surrounding shape at one end and to the inside of the conical flow guiding umbrella 8 at the other end to support the filter cotton.

[0039] Filter cotton is installed between the inner stainless steel fixing net 104, the middle stainless steel fixing net 103 and the outer stainless steel fixing net 102, and is wound into a cylindrical shape and installed between the upper filter layer cover 7 and the lower filter layer cover 9.

[0040] Working principle: The utility model includes a tank body 1, a tank body upper cover 2, an air inlet 3, an air outlet 4, a drain port 5, an intake pipe 6, an upper filter layer cover 7, a conical flow guiding umbrella 8, a lower filter layer cover 9, an intake pipe fixing seat 10, stainless steel branch pipes 101, an outer stainless steel fixing net 102, a middle stainless steel fixing net 103, and an inner stainless steel fixing net 104. The utility model is a steam-water separator used in the field of soil remediation. When in use, the air inlet 3 is flange-connected to the suction pipe of the soil remediation device, and the gas enters the intake pipe 6 through the air inlet 3 and is ejected at high speed through the small pores on the intake pipe 6. The flow rate is suddenly slowed down by the obstruction of the conical flow guiding umbrella 8 to achieve steam-water separation. The separated liquid drips along the conical flow guiding umbrella to the lower filter layer cover 9, flows through the water outlet hole to the bottom of the tank body 1, and then enters the sewage treatment system through the drain port 5. The separated gas sequentially passes through the first filter layer supported by the stainless steel brackets 101 and the second and third filter layers fixed by the inner stainless steel fixing net 104, the middle stainless steel fixing net 103, and the outer stainless steel fixing net 102 and enters the tank body 1, and then enters the waste gas treatment device through the air outlet 4.

[0041] The steam-water separator of the utility model uses a dual separation mechanism. After the gas enters the device, the flow rate is slowed down by the conical flow guiding umbrella, and it collides and condenses for primary gas-liquid separation. Then, after the secondary gas-liquid separation of the first filter layer, it leaves the conical flow guiding umbrella. The gas passes through the second and third filter layers for tertiary gas-liquid separation and is discharged through the air outlet, improving the separation efficiency, having a small particle size of the separated water droplets, and thoroughly separating gas and liquid.

[0042] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than a limitation on the protection scope of the utility model. Any simple modification or equivalent replacement of the technical solution of the utility model by those of ordinary skill in the art does not depart from the essence and scope of the technical solution of the utility model.
