Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of biomass condensate collection, and particularly relates to a collection device for biomass condensate. Background Art
[0002] Biomass condensate refers to the condensate in a processing container after the steam introduced into a closed material processing container containing biomass materials condenses. The existing biomass condensate, such as bamboo material condensate, is collected and stored by directly discharging it into an open underground pool for natural cooling. However, due to the high COD (chemical oxygen demand) content and high chroma of bamboo material condensate, the above collection method is prone to environmental pollution. Since the temperature of the condensate discharged from the material processing container is relatively high (boiling point temperature or close to the boiling point temperature), directly discharging it into the underground pool cannot effectively cool the condensate, increasing the cooling time of the condensate; moreover, collecting and storing the condensate in an open underground pool also greatly increases the risk of the condensate being contaminated by bacteria.

[0025] Embodiment 1.
[0026] Refer to Figure 1As shown in the figure, as an embodiment of the present utility model, a device for collecting biomass condensate is provided, specifically a device for collecting bamboo material condensate, which includes a material processing container 1 and a closable collecting container 2. The closed state of the collecting container 2 means a state that can block the entry of external bacteria, but air can still pass through. An closable opening for feeding biomass-containing materials and a steam inlet 4 for introducing steam are provided on the material processing container 1. The biomass material is bamboo material. A conveying pipeline 3 is connected between the material processing container 1 and the collecting container 2. A cooler 5 is installed on the conveying pipeline 3, and a valve 6 is installed on the conveying pipeline 3 near the material processing container 1. That is, the collecting container 2 and the cooler 5 are separately arranged. The cooler 5 is installed on the conveying pipeline 3 between the valve 6 and the collecting container 2, and the front and rear ends of the conveying pipeline are respectively connected between the position below the liquid level of the corresponding condensate in the material processing container 1 and the collecting container 2. By introducing steam into the material processing container 1 to perform steam treatment on the bamboo material and maintaining it for a certain period of time at high temperature, the obtained condensate is then discharged by opening the valve 6 under the initial internal pressure of the material processing container 1 (including the remaining steam), or the condensate in the material processing container 1 can also flow out automatically by using the liquid level difference, so that the condensate in the material processing container 1 is conveyed and discharged through the conveying pipeline 3, cooled by the cooler 5 and then conveyed and introduced into the collecting container 2 for closed collection, and then the condensate is used as a microbial culture medium. This collection method is beneficial to the rapid cooling of the condensate, accelerates the cooling rate of the condensate, reduces the destruction of nutrients in the condensate, reduces the contact between the condensate and miscellaneous bacteria, and reduces the risk of the condensate being contaminated by bacteria.
[0027] Of course, biomass includes animals, plants, microorganisms and their production wastes. The device for collecting biomass condensate of the present utility model can also be used for collecting condensate of other biomass materials except bamboo materials, such as wood, bamboo-wood-grass mixed materials, etc.
[0028] Of course, in other cases, air treated by sterilization can also be introduced into the collecting container to cool the condensate collected in the collecting container and avoid contamination at the same time.
[0029] In addition, in other cases, when the volume of the collecting container is small, it is also possible not to use a cooler. By relying on external heat radiation of the collecting container and indirect heat exchange with the air outside the collecting container for cooling, the condensate can also be quickly cooled in the collecting container, and the risk of the condensate being contaminated by bacteria is further reduced.
[0030] In this embodiment, the conveying pipeline 3 between the cooler 5 and the collection container 2 is a detachable flexible or rigid pipe, which is convenient for replacement and maintenance or adjustment of the number of collection containers 2 according to requirements. Of course, in other cases, the conveying pipeline can also be a non-detachable flexible or rigid pipe.
[0031] In this embodiment, the cooler 5 is an indirectly heat-exchanging cooler 5, which ensures the effective transfer of heat during the heat exchange process, and at the same time avoids the problems of unexpected chemical reactions, contamination or dilution that may occur to the condensate due to direct contact, ensuring the efficiency and safety of the cooling process.
[0032] Embodiment 2. For the sake of brevity, this embodiment mainly describes the differences from Embodiment 1.
[0033] Refer to Figure 2 As shown, as an embodiment of the present utility model, a device for collecting biomass condensate is provided. The collection container 2 includes a first collection container 21 and a second collection container 22. The conveying pipeline 3 includes a first conveying pipeline 31 and a second conveying pipeline 32. The front and rear ends of the first conveying pipeline 31 are respectively connected between the position below the liquid level of the condensate in the material processing container 1 and the first collection container 21, and the front and rear ends of the second conveying pipeline 32 are respectively connected between the position above the liquid level of the condensate in the material processing container 1 and the second collection container 22. After the water vapor is introduced into the material processing container 1 to perform steam treatment on the bamboo material, first, the valve 6 on the second conveying pipeline 32 is opened, and the water vapor in the material processing container 1 is conveyed and discharged through the second conveying pipeline 32, and after being cooled by the cooler 5 on the second conveying pipeline 32, it is conveyed and introduced into the second collection container 22 for collection. After the water vapor in the material processing container 1 is discharged, preferably until the internal pressure of the material processing container 1 is equal to the atmospheric pressure, then the valve 6 on the first conveying pipeline 31 is opened to discharge the condensate in the material processing container 1, and finally, after being cooled by the cooler 5 on the first conveying pipeline 31, it is conveyed and introduced into the first collection container 21 for collection. Since the water vapor can entrain the volatile solutes generated during the bamboo material processing, and there are many antibacterial substances in the volatile solutes, this technical solution first discharges and cools the water vapor for collection, thereby realizing the preliminary separation of the volatile solutes and non-volatile solutes in the material processing container 1, reducing the content of volatile solutes in the condensate collected in the first collection container 21, further reducing the antibacterial substances in the condensate, and at the same time reducing the destruction of nutrients in the condensate, reducing the contact between the condensate and miscellaneous bacteria, and reducing the risk of condensate contamination by bacteria, making the condensate more suitable for use as a microbial culture medium.
[0034] Of course, the valves of the first conveying pipeline 31 and the second conveying pipeline 32 can also be opened simultaneously to collect condensate and water vapor at the same time. Or the valve of the first conveying pipeline 31 below can be opened first to collect condensate. After the condensate in the material processing container 1 is discharged, the valve of the second conveying pipeline 32 can be opened to collect the water vapor inside.

[0036] As an embodiment of the present utility model, a collection device for biomass condensate is provided.

[0038] As an embodiment of the present utility model, a collection device for biomass condensate is provided. The collection container 2 and the cooler 5 are integrally arranged. The cooler 5 is a jacket-type cooler installed on the outer wall of the collection container 2, or a coil-type or shell-and-tube cooler installed on the collection container 2, so that the collection container 2 becomes a cooling and collection container integrating cooling and collection, saving the length and quantity of the conveying pipeline 3. The rear end of the valve 6 is connected to a plurality of cooling and collection containers through a plurality of conveying pipelines 3, so as to realize the collection of condensate in separate containers after unified cooling.
[0039] Example 5. For the sake of brevity, this example mainly describes the differences from Example 1.
[0040] As an embodiment of the present utility model, a collection device for biomass condensate is provided. It further includes a closable temporary storage container connected between the material processing container 1 and the cooler 5. There are two valves 6, and the two valves 6 are respectively installed on the conveying pipelines 3 between the material processing container 1 and the temporary storage container and between the temporary storage container and the cooler 5. This container can realize the collection and temporary storage of multi-batch condensate in the material processing container 1, and then the condensate is uniformly cooled and collected through the cooler 5 and the collection container 2 at one time, without the need for frequent cooling and collection operations, which is more convenient and fast.
[0041] Example 6. For the sake of brevity, this example mainly describes the differences from Example 1.
[0042] As an embodiment of the present utility model, a collection device for biomass condensate is provided. It further includes a liquid pump. A branch pipeline is connected to the side of the conveying pipeline 3, and the liquid pump is installed on the branch pipeline, so that when the pressure in the material processing container 1 is not enough to automatically press out the condensate, the liquid pump can be started to smoothly export and collect the condensate.
[0043] Although the present utility model is specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes made to the present utility model in form and detail fall within the protection scope of the present utility model without departing from the spirit and scope of the present utility model defined by the appended claims.
