Embodiment 1

[0040] Such as figure 1 As shown, a dedusting and decoking device for high-tar and high-dust high-temperature gas includes a filter device, and the filter device includes an inlet for high-tar and high-dust high-temperature gas, and a high-temperature gas for discharging the filter export. The filter device in this embodiment is composed of several filters 12, which are fixed on the housing device through the support plate 10, and the filters 12 are divided into several filter areas. In this embodiment, there are 28 filters 12, which are evenly divided into four filter areas. Filter 12 is a ceramic dust removal pipe. The filter can also adopt other filter devices suitable for filtering gases such as dust tar. The number of filters can be set according to actual needs, and can be from several to hundreds. The root number of filters in each filter area can also be set to multiple according to actual conditions. Such as figure 2 Shown is a housing arrangement for housing a...

Embodiment 2

[0046] Such as image 3 As shown, it is basically the same as Embodiment 1, the difference is that the filter device is composed of several filters 12, the filter 12 is fixed on the housing device through the support plate 10, and the blowing gas delivery pipe includes Conveying the main pipe 20 and the conveying branch pipe 21 , each filter 12 corresponds to a conveying branch pipe 21 , and the conveying branch pipe 21 extends into the inside of the filter 12 , and the blowing valve 19 is set on the conveying main pipe 20 . With the above-mentioned device, the conveying branch pipe extends into the inside of the filter, and the backflushing is more thorough. In the structure of this embodiment, a storage device for storing substances that contribute to tar combustion catalysis, the storage device is connected to the delivery main pipe. The substances in the storage device can be added during backflushing, so that during the high-pressure backflushing process, the tar burning...

Embodiment 3

[0049] Such as figure 1 with 4 As shown, it is basically the same as Embodiment 1, and the difference is that in this embodiment, two filter devices and a shell device are provided, and the two sets of devices share a high-temperature gas circulation device and a high-temperature pressurized gas source 1 . With two sets of devices, one device can be filtered and purified, and the other device can be regenerated to avoid the problem of failure to filter and purify due to shutdown.

Abstract

The invention relates to a high-tar high-dust high-temperature gas dedusting and decoking device and method thereof, including a filtering device; a shell device for accommodating the filter; a blowback device for cleaning the dust on the filter; wherein , also includes a high-temperature gas circulation device, the high-temperature gas circulation device includes a circulating gas heating device for heating the purified gas coming out of the filter, the inlet port of the circulating gas heating device is connected with the outlet of the filter, and the circulating gas heating device The outlet end of the device communicates with the shell device, and the circulating gas heating device is provided with a gas supply device for supplementing oxygen-containing gas. The device of the present invention can effectively remove the dust and tar pollution on the filter by setting the combination of back blowing and combustion, effectively improve the service life of the filter and the filtering efficiency, and reduce the regeneration time of the filter from 60h To 10h, the service life of the filter has been increased by more than 50%.

Description

technical field [0001] The invention relates to a dedusting and decoking device and method for high-tar and high-dust high-temperature gas, belonging to the field of gas purification. Background technique [0002] In recent years, with the rise of low-carbon economy, the substitution of fossil energy such as coal, natural gas and oil by biomass has become a research hotspot in the field of new energy, which has important strategic significance and has been given enough attention by countries all over the world. Among the many new technologies for biomass energy utilization, biomass gasification technology is one of the fastest-growing and relatively mature engineering technologies. Biomass gasification is one of the important ways to convert primary energy into clean secondary energy. Its products are mainly combustible gases, which can also be processed into high-quality gases such as syngas and hydrogen after advanced treatment. Biomass gasification technology has broad a...
