Cloth bag lower pattern plate fixing device for circular cloth bag dust remover and using method thereof

Abstract

The invention relates to a cloth bag lower pattern plate fixing device for a circular cloth bag dust remover. The device consists of a fixed lower pattern plate and a cloth bag mounting buckle, and afilter bag is fixed on the fixed lower pattern plate by the cloth bag mounting buckle; the fixed lower pattern plate consists of cloth bag mounting rings, a mounting ring connecting piece and a towerwall connecting plate; the cloth bag mounting ring is a fixing ring of the filter bag; and the mounting ring connecting piece connects the adjacent cloth bag mounting ring into a whole. The using method of the cloth bag lower pattern plate fixing device for the circular cloth bag dust remover comprises the steps that firstly, when the fixed lower pattern plate is installed, it is guaranteed that the filter bags can be vertically installed in the two outermost circles of filter bag installing holes of the upper pattern plate of the cloth bag dust remover through a laser pen, and then the lowerpattern plate is installed and fixed; after the fixed lower pattern plate is installed, a cloth bag mounting buckle is installed in each cloth bag mounting ring, the cloth bag mounting buckles in thefixing device can effectively fix the filter bag on the fixed lower pattern plate in a soft mode, and damage, caused by compression and friction between the cloth bag mounting buckles and the fixed lower pattern plate, to the filter bag is prevented.

Description

technical field [0001] The invention relates to the technical field of flue gas dust removal, in particular to a lower flower plate fixing device for a round bag filter and a method for using the same. Background technique [0002] The bag filter is a dry dust filter device, which is widely used in the flue gas purification of coal-fired boilers, garbage incinerators and other industrial boilers. The bag filter mainly purifies the dusty gas through the filtering effect of the filter bag made of textile filter cloth or non-woven fabric. After the dusty flue gas enters the bag filter, the dust in the flue gas is blocked because it cannot pass through the pores of the filter bag and settles down into the ash hopper. After passing through the filter bag, the flue gas becomes clean flue gas and flows out of the bag filter. In my country, the round bag filter is more and more used because it adds the effect of the cyclone dust collector on the basis of the filtering effect of the...

Problems solved by technology

However, because the flue gas of this kind of dust collector enters the wind tangentially from the upper part, due to the effect of the air flow, the outermost circles of bags of the bag filter will shake violently, causing the filter bag to collide with the cylinder wall and the filter bag. The dust content at the back end of the flue gas purification system exceeds the standard, which affects the treatment performance of the flue gas purification system

In severe cases, it may even cause the boiler to shut down, resulting in huge losses

In addition, the process of locating the damaged cloth bag and replacing it is complicated and cumbersome, and the cloth bag is expensive
