Embodiment 1

[0025] Such as figure 1 As shown, the compact continuous filter device for high-temperature easy-to-separate mixture gas includes a cavity 2 between the inlet of the filter device and the outlet of the filter device. A filter device is installed in the cavity, and a high-temperature Heating body; the filter device includes two filter mechanisms, each filter mechanism is equipped with a regeneration material inlet 3, and three high temperature resistant filter elements 1 and two filter tubes 7 are installed in the filter mechanism, and the electric furnace wire is wound on the filter element 1 and filter tube 7. The filter elements 1 and filter tubes 7 are connected alternately, and along the flow direction of the high-temperature and easy-to-separate mixed gas, the pores of the filter element 1 gradually decrease, and the pores on the three filter elements 1 gradually decrease, which can effectively buffer the mixed gas flow to the first filter element 1 impact, reducing the ...

Embodiment 2

[0033] A compact continuous filter device for a mixture of high-temperature and easily precipitated substances, including a cavity 2 between the inlet port of the filter device and the gas outlet port of the filter device, a filter device is arranged in the cavity, and a high-temperature heating element is installed on the filter device; The filter device includes three filter mechanisms, the filter mechanism is equipped with a regeneration material inlet 3, and each filter mechanism is equipped with a high temperature resistant filter element 1 and a filter tube 7, and the electric furnace wire is wound on the filter element 1 and on filter tube 7. The filter tube 7 is distributed in an S shape along the gas direction, which can increase the contact area between the high-temperature easy-to-separate mixture gas and the filter pipe 7, and increase the quality of the filtered gas. The two ends of the separation wall between the filter mechanisms are provided with through holes,...

Abstract

The invention discloses a compact continuous filter device and a filter method for a high-temperature, easy-to-separate mixture gas, which comprises a cavity between the filter device inlet and the filter device gas outlet, and a filter device is arranged in the cavity. A high-temperature heating element is installed on the filter device; the filter device includes at least two filter mechanisms, and the filter mechanism is provided with a regeneration material inlet, and a high-temperature-resistant filter element and a filter tube are installed in the filter mechanism, and the filter element is connected to the filter tube. The two ends of the separation wall between the filter mechanisms are provided with through holes, and pressure sensing doors are installed on the through holes. When a filter mechanism works for a period of time, because the filter element and filter tube are blocked by easy precipitates and cannot work normally, the induction door will automatically switch the airflow to another filter mechanism by sensing the pressure in the filter mechanism to ensure the uninterrupted filtration process , so as to realize the periodic alternate work and regeneration of two or more filter mechanisms, and improve the automation of the filter device.

Description

technical field [0001] The invention relates to a filtering device and a method thereof, in particular to a compact continuous filtering device and a filtering method of a high-temperature easy-to-separate mixture gas. Background technique [0002] In the manufacturing process of chemical industry, petroleum and other industries, high-temperature dusty gases are often produced. In these high-temperature dusty gases, carbon-containing and easy-to-precipitate substances such as tar coke and asphalt-like substances are enriched during the filtration process and enriched on the filter body. As a result, the filter body loses its filtering function, and the replacement of the filter body will inevitably bring about the problem of shutting down production. For large-scale chemical equipment with continuous operation, shutting down for maintenance will inevitably bring huge economic losses. So far, whether it is domestic or foreign, the problem of filtering and dedusting the mixed ...
