A full-scale honeycomb catalyst reaction unit hydraulic sealing system and its working method

Abstract

The invention discloses a full-size honeycomb catalyst reaction unit hydraulic sealing system and a working method thereof. The full-size honeycomb catalyst reaction unit hydraulic sealing system comprises a reactor system, a hydraulic station, a corrugated pipe system, a hydraulic tightening system, a guide tank and a power source controller, wherein the power source controller, the hydraulic station, the corrugated pipe system, the reactor system and the hydraulic tightening system are sequentially connected; the guide tank is arranged under the reactor system. The working method comprises the following steps: when an experiment is performed, starting the hydraulic station, mutually tightening reaction furnaces on the guide tank, and hydraulically sealing the whole reactor system, so as to dynamically connect the reaction furnaces; when reaction is finished, closing the system; after a hydraulic cylinder releases pressure, disassembling a catalyst. The full-size honeycomb catalyst reaction unit hydraulic sealing system has the advantages that the dynamic connection between the reaction furnaces can be realized, and the possibility of air leakage due to heat expansion and cold shrinkage is decreased.

Description

technical field [0001] The invention belongs to the technical field of air pollution control in environmental engineering, and in particular relates to a hydraulic sealing system of a full-scale honeycomb catalyst reaction unit and a working method thereof. Background technique [0002] On September 22, 2011, the Ministry of Environmental Protection promulgated a new standard GB 13223-2011 "Emission Standard of Air Pollutants for Thermal Power Plants". It is required that from January 1, 2012, the nitrogen oxide emission of newly built thermal power units should reach 100 mg / m3; They are also required to reach 100 mg / m3. This means that it will take two to three years to complete the transformation of units with an installed capacity of hundreds of millions of kilowatts, and the corresponding environmental protection equipment and materials will be in short supply, especially the gap between supply and demand of catalysts, the main raw materials for flue gas denitrification...

AI Technical Summary

Problems solved by technology

The catalytic activity of the catalyst is the key to the denitrification efficiency. Currently, the catalyst activity detection and evaluation devices on the market are becoming more and more mature, but there are still some technical difficulties that are difficult to break through.

For example: Catalyst reactors need to be replaced frequently, so the reactor needs to be designed to be easily disassembled, which in turn increases the probability of thermal expansion and contraction leading to reactor air leakage

[0003] The patent (201510072449.3) is a lifting device for the reactor of the denitrification catalyst activity detection system. A reactor device is designed to facilitate the removal and replacement of the catalyst. However, the patent does not propose to solve the problem of air leakage in the reactor due to thermal expansion and contraction. Methods

Patent (201520615340.5) A double reaction furnace activity detection device for SCR denitrification catalyst, the device includes a gas cylinder, a water vapor evaporator, a mixing preheating furnace, a reaction furnace, a condensation absorption device, and a flue gas analyzer, in which the reaction furnaces are two in parallel The vertical reaction furnace, the two vertical reaction furnaces are simply connected in parallel without any anti-leakage measures
