Problems solved by technology

In the activated coke flue gas purification project, after the saturated activated coke is preheated and heated in the regeneration tower, the regeneration gas is released in the square bin in the middle of the regeneration tower, and the regeneration gas is pumped to the acid production area by a fan. , the release of regenerative gas in the square bin in the middle of the regeneration tower is the core of the entire regeneration tower, but the key factor affecting its release efficiency is the temperature of the active coke and the ambient pressure of the release of the regeneration gas. If the pressure is high, it will seriously affect the release of the regeneration gas from the active coke Conversely, if the pressure is low, the concentration of regeneration gas going to the acid production will be reduced, which will increase the difficulty of acid production and reduce the efficiency;
[0003] Therefore, the measurement of the ambient pressure of the regeneration gas released by the active coke is particularly important. In the square bin in the middle of the regeneration tower, the active coke particles and the regeneration gas are in a mixed state, and it is impossible or inappropriate to use a conventional pressure sampling device.

Abstract

The invention belongs to the field of automatic environmental detection and particularly relates to a pressure sampling device for separation of active coke particles and regenerative gas. The deviceis characterized by comprising a sampled gas buffering tank arranged on a side wall of a gas-solid sealing plate for sealing the active coke particles and the regenerative gas, a group of gas-solid separating and guiding plates arranged at a connection surface of the side wall of the gas-solid sealing plate and the sampled gas buffering tank, a joint arranged at the upper end of the sampled gas buffering tank, a sampling tube connected to the joint, an inspection ash storing box arranged at the lower part of the sampled gas buffering tank, an inspection cover arranged at the opening of the inspection ash storing box and a disassembly and assembly lifting ring arranged on the inspection cover. The device disclosed by the invention has the advantages that under the circumstance of not influencing the operating state of the active coke particles, the purpose of introducing the gas in the gas-solid mixed state into a pressure transmitter can be realized and the online real-time detection is completed.

Description

technical field [0001] The invention belongs to the field of automatic detection of environmental protection, and in particular relates to a pressure sampling device for separating active coke particles and regeneration gas. Background technique [0002] With the improvement of industrial flue gas emission standards, the flue gas purification system for sintering production has gradually become an essential process. At present, flue gas purification mainly includes dry and wet desulfurization and denitrification processes. Especially in the past two years, the activated coke dry desulfurization and denitrification process has become the first choice for sintering flue gas purification. In the activated coke flue gas purification project, after the saturated activated coke is preheated and heated in the regeneration tower, the regeneration gas is released in the square bin in the middle of the regeneration tower, and the regeneration gas is pumped to the acid production area ...
