Horizontal circulating type dust collector

Abstract

The invention relates to dust removal devices, in particular to a horizontal circulating type dust collector. The horizontal circulating type dust collector comprises a cylinder, an air inlet pipe port, two clean air exhaust pipe ports, two dust separating pipes and two rectangular dust exhaust pipe ports. The cylinder is horizontally arranged with two ends sealed by sealing end caps, the air inlet pipe port is arranged above the middle of the cylinder and is tangentially connected with the cylinder, the clean air exhaust pipe ports are arranged in the outer sides of the sealing end caps at two ends of the cylinder respectively, the dust separating pipes are arranged on the inner sides of the sealing end caps respectively, the rectangular dust exhaust pipe ports are downwardly mounted at two ends of the cylinder tangentially and perpendicularly, and the air inlet pipe port, the clean air exhaust pipe ports and the rectangular dust exhaust pipe ports are connected with a pipeline system. The horizontal circulating type dust collector overcomes the defects that a conventional cyclone dust collector is long in flowing route, high in pressure drop and energy consumption, low in operation flexibility and remarkable in amplification effect and the like and effectively eliminates influences on dust collection efficiency from short-circuit current and upper vortex in the cyclone dust collector.

Description

1. Technical field [0001] The invention relates to dust collector equipment, in particular to a horizontal circulation dust collector. 2. Background technology [0002] The traditional cyclone dust collector is a vertical structure, which uses the principle of the circulation of the dust-laden gas inside the dust collector and the principle of the dust itself being affected by gravity to separate the dust from the high-speed airflow and discharge the clean gas to the outside. [0003] The traditional cyclone dust collector consists of an inlet pipe, an exhaust pipe, a cylinder, a cone and an ash hopper. When the cyclone dust collector starts to work, the dusty gas from the outside is sent to the interior of the dust collector body through the air inlet by the fan. Under the action of the wind pressure, the dusty gas whirls down along the inner wall of the dust collector body. The dust separated by the cyclone dust collector is discharged through the dust outlet located unde...

Problems solved by technology

[0004] Obviously, the traditional cyclone dust collector has the following defects: ①The whirling path of the dust flowing into the interior is too long, so the contact time of the dust with the inner wall of the dust collector body is too long during the whirling down process, so the noise cannot be reduced; ②The air flow path Too long will lead to excessive pressure loss; ③ All kinds of dust enter the interior of the ash storage hopper with residual whirling force, which will cause the dust already collected in the ash storage hopper to generate secondary dust, thus reducing the dust collection efficiency

[0005] These defects eventually lead to the disadvantages of long fluid flow path and large velocity gradient in the traditional cyclone dust collector, so the pressure drop is large, the energy consumption is high, the operation stability is poor, and the amplification effect is significant.

In addition, due to its own structural design, the traditional cyclone dust collector must have an upper vortex near the inlet of the exhaust pipe (some people call it a short-circuit flow).

Research analysis shows that due to the existence of the upper vortex, some dust particles return to the clean air flow and are taken out of the cyclone dust collector, which is the basic reason for the low dust removal efficiency of the traditional cyclone dust collector
