Abstract

The invention invents an inertial dust collector with double ash hoppers. The nozzle acceleration is used at the entrance to increase the inlet flow velocity of the dust-laden gas, so that the velocity reaches a suitable value. After the gas is accelerated, it is vertically injected into the dust collector and hits the first obstacle. - Tilted baffles. After the first deceleration by collision and friction, the larger particles are restrained by the inclined baffle in the direction of movement, and then decelerated into the ash hopper 1, and the smaller dust particles are further decelerated with the turning of the airflow, and enter the ash hopper 2 due to centrifugal force. The dust collector is equipped with multiple cross-sectional mutations and inclined baffles, mainly to increase friction and reduce the fluid flow rate as a whole. Compared with the existing inertial dust collector, the overall volume of the dust collector is greatly reduced, and it can be more flexibly adapted to some narrow spaces. If it is used in a large space, multiple dust collectors can be connected in parallel. The left side of the ash hopper 2 is provided with a pressure balance hole, which is used to balance the atmospheric pressure between the ash hopper 2 and the external environment, improve the fluid state in the ash hopper 2, and facilitate better removal of dust. The inertial dust collector can not only reduce the secondary dust, but also reduce the resistance in the process of gas flow, and also improve the dust removal efficiency to a certain extent. Moreover, the reduction of the inlet wind pressure directly reduces the power of the fan, achieving the effect of saving energy.

Description

A double ash hopper inertial dust collector

technical field

The invention relates to the field of environmental protection technical equipment, in particular to an inertial dust collector with double ash hoppers.

Background technique

At present, the known inertial dust collectors include impact dust collectors and return dust collectors. The former dust collector mainly uses one or several baffles to block the progress of the airflow, so that the dust particles in the airflow are separated. The gas flow resistance of the form dust collector is small, but its dust removal efficiency is low. The characteristic of the latter type of dust collector is that the intake air flow is divided into small airflows by baffles. In order to make any airflow have the same smaller radius of gyration and larger angle of gyration, various baffle structures can be used. The most typical The most important thing is the louver baffle. Although the louver baffle can increase the speed before the sharp turn of the airflow, it can effectively improve the separation efficiency, but if the speed is too high, it will cause the trapped particles to fly again. Therefore, in order to overcome the secondary dusting of the existing dust collector, the gas flow resistance is large and the dust removal efficiency is low. Therefore, the present invention provides an inertial dust collector, which improves and optimizes the original device. The inertial dust collector can not only reduce the secondary dust, but also reduce the resistance in the process of gas flow, and also improve the dust removal efficiency to a certain extent. Moreover, the reduction of the inlet wind pressure directly reduces the power of the fan, achieving the effect of saving energy.

Contents of the invention

The invention is an inertial dust collector with double ash hoppers. The problem to be solved by the invention is to reduce the secondary dust phenomenon that is easy to occur in the dust removal process, reduce the resistance in the gas flow process, and improve the dust removal efficiency to a certain extent.

The technical scheme adopted in the present invention:

Provided is an inertial dust collector with double ash hoppers, including a dusty gas inlet, a purified gas outlet, ash hoppers, corners, baffles, pressure balance holes, etc.

After adopting the above structure, the dust-laden gas will fall into the two ash hoppers through the action of inertial force and centrifugal force by setting multiple cross-sectional mutations and inclined baffles, and the purified gas will be discharged through the purified gas outlet.

At the inlet, nozzle acceleration is used to increase the inlet flow velocity of the dusty gas, so that the velocity reaches a suitable value. After acceleration, the gas is vertically injected into the dust collector and collides with the first obstacle - the inclined baffle. After the first deceleration by collision and friction, the larger particles are restrained by the inclined baffle in the direction of movement, and then decelerated into the ash hopper 1, and the smaller dust particles are further decelerated with the turning of the airflow, and enter the ash hopper 2 due to centrifugal force. The dust collector is equipped with multiple cross-sectional mutations and inclined baffles, mainly to increase friction and reduce the fluid flow rate as a whole. Compared with the existing inertial dust collector, the overall volume of the dust collector is greatly reduced, and it can be more flexibly adapted to some narrow spaces. If it is used in a large space, multiple dust collectors can be connected in parallel. As shown in the sectional view of the front view of the dust collector, there is a pressure balance hole on the left side of the ash hopper 2, which functions to balance the atmospheric pressure between the ash hopper 2 and the external environment, improve the fluid state in the ash hopper 2, and facilitate better removal of dust. In order to prevent dust from clogging the pressure balance hole, its position is arranged on the upper part of the ash hopper 2. In order to prevent dust from running out of the pressure balance hole, a fine filter device should be arranged outside the hole.

Specific implementation measures

The dust-laden gas is accelerated through the nozzle at the entrance to make the flow rate reach a suitable value. The accelerated gas is injected into the inclined baffle 1, and is decelerated by collision and friction for the first time. The larger particles are restrained by the inclined baffle in the direction of movement, and then It is decelerated into the direction of the ash hopper 1, and then falls into the ash hopper 1 through the frictional deceleration of the baffle 2 and the baffle 3. The smaller dust particles are further decelerated with the turning of the airflow, and enter the direction of the ash hopper 2 due to centrifugal force, and then pass through the baffle. The effect of the frictional deceleration of the plate 4 baffle 5 falls into the ash hopper 2 . The purified gas after dust removal is discharged from the purified gas outlet. Compared with the existing inertial dust collector, the overall volume of the dust collector is greatly reduced, and it can be more flexibly adapted to some narrow spaces. If it is used in a large space, multiple dust collectors can be connected in parallel. As shown in the cutaway front view of the dust collector, there is a pressure balance hole on the left side of the ash hopper 2, which functions to balance the atmospheric pressure between the ash hopper 2 and the external environment, improve the fluid state in the ash hopper 2, and facilitate better dust removal. In order to prevent dust from clogging the pressure balance hole, its position is arranged on the upper part of the ash hopper 2. In order to prevent dust from running out of the pressure balance hole, a fine filter device should be arranged outside the hole.
