Technical Field

The utility model relates to a bag collector technical field, concretely relates to bag collector that space utilization is high.

Background

The bag type dust collector is a dry dust collector, also called a filtering dust collector, which is a dust collector for collecting solid particles in dust-containing gas by using a dust filter bag.

When the bag type dust collector in the prior art is used for treating the flue gas of the high-temperature industrial boiler, the high-temperature flue gas coming out of a hearth firstly enters the heat exchanger for cooling and then enters the dust collector for dust removal treatment, the dust in the heat exchanger is seriously accumulated and is difficult to clean up over time, the heat exchange efficiency is influenced, and the heat exchanger and the dust collector are of a split structure, so that the installation is complex and the occupied area is large. In addition, the existing bag type dust collector adopts an integral type dust hopper, the taper of the dust hopper is required to be larger than the repose angle of dust, and the dust can be ensured to smoothly slide to a dust discharging opening at the bottom end of the dust hopper. Therefore, the integral ash bucket has larger size, and puts higher requirements on the installation space of the dust remover.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model provides a bag collector that space utilization is high is integrated to well box inside with heat exchange assemblies to adopted the ash bucket that has used a plurality of block formulas, greatly reduced bag collector's overall dimension, improved space utilization.

The connection sequence of the cold water main pipe, the hot water main pipe and the four heat exchange assemblies is opposite, so that the resistance among the heat exchange assemblies is balanced, and the heat exchange is more uniform.

Furthermore, one end, far away from the ash hopper, of the overflow branch pipe is communicated with a dust storage pipe, the dust storage pipe is vertically arranged, the lowermost end of the dust storage pipe is fixedly connected with a blind plate, and an induction sensor is fixedly arranged on the dust storage pipe. The dust that flows out among the overflow branch pipe can flow into in the dust storage pipe to pile up on the blind plate of dust storage pipe bottom, inductive transducer senses when the dust storage pipe has the dust, sends the police dispatch newspaper to control system, reminds operating personnel in time to check whether the ash bucket appears unloading smoothly the circumstances.

Furthermore, the middle box body is fixed on the ground through the equipment supporting legs.

Furthermore, every all be equipped with a high-order charge level indicator and low level charge level indicator on the ash bucket, high-order charge level indicator's height is higher than low level charge level indicator's height. And when the height of the dust in the dust hopper is higher than the high-level material level timing, starting dust discharging of the dust hopper, and when the height of the dust in the dust hopper is lower than the low-level material level timing, stopping dust discharging.

Compared with the prior art, the beneficial effects of the utility model are that:

the heat exchange assembly is arranged in the middle box body, and the heat exchange assembly and the dust remover are installed in an integrated manner; the bottom of the middle box body is fixedly connected with a plurality of parallel ash hoppers. These can both greatly reduced dust remover's area, improve space utilization.

The heat exchange assembly is simple in structure, and the heat exchange assembly can be conveniently cleaned when the dust removal filter bag is replaced. The connection sequence of the cold water main pipe, the hot water main pipe and the four heat exchange assemblies is opposite, so that the resistance among the heat exchange assemblies is balanced, and the heat exchange is more uniform.

The dust that flows out among the overflow branch pipe can flow into in the dust storage pipe to pile up on the blind plate of dust storage pipe bottom, inductive transducer senses when the dust storage pipe has the dust, sends out the police dispatch newspaper to control system, has reduced because of the ash bucket unloads the probability that the ash is smooth and influence normal production.
