Harmful gas filtering equipment for chemical pharmacy

Abstract

The invention discloses harmful gas filtering equipment for chemical pharmaceutical. The harmful gas filtering equipment structurally comprises a filtering device, a water outlet pipe, supporting legs, a gas outlet pipe, a gas inlet pipe, a water tank, a water pump and a circulating water pipe, wherein the lower end of the filtering device is fixedly provided with a water outlet pipe in an embedded manner, the water outlet pipe communicates with the filtering device, and the supporting legs are welded onto the lower end of the filtering device. According to the invention, the outer side surface of a filter element device is comprehensively sprayed and cleaned through seven rows of vertical nozzles; as the filter element device rotates, excessive extrusion of washing force to the filter element device is relieved, and the comprehensive cleaning effect of the filter element device is improved; waste gas enters a gas guide pipe and is annularly and dispersedly discharged, the waste gas is dispersed and filtered in the multi-layer filter element, and a part of harmful gas sinks and enters a gas spraying pipe; the spraying capacity of the harmful gas is improved through a gas outlet nozzle; and the gas spraying pipe and the multi-layer filter element rotate reversely, so the gas pressure of the harmful gas passing through the interior of the multi-layer filter element is improved, and it is ensured that the harmful gas is effectively filtered.

Description

technical field [0001] The present invention relates to the field of chemical industry and pharmacy, more specifically, relates to a kind of harmful gas filtering equipment for chemical industry and pharmacy. Background technique [0002] In the chemical and pharmaceutical process, it is easy to produce some harmful gases. This part of the harmful gases needs to be filtered through the gas filter. The particles in the harmful gas are filtered through the multi-layer filter element inside the gas filter. The flushing device can flush the filter element, so that the filter element can effectively filter harmful gases. However, when the backwashing device flushes the filter element, the filter element is directly fixed on the inner wall of the filter, and the backwashing will clean the water Flush directly from the bottom of the filter element upwards, and the clean water is easily blocked by the bottom of the filter element, the cleaning effect of the upper end of the filter e...

[0002] In the chemical and pharmaceutical process, it is easy to produce some harmful gases. This part of the harmful gases needs to be filtered through the gas filter. The particles in the harmful gas are filtered through the multi-layer filter element inside the gas filter. The flushing device can flush the filter element, so that the filter element can effectively filter harmful gases. However, when the backwashing device flushes the filter element, the filter element is directly fixed on the inner wall of the filter, and the backwashing will clean the water Flush directly from the bottom of the filter element upwards, and the clean water is easily blocked by the bottom of the filter element, the cleaning effect of the upper end of the filter element is reduced, while the gas is filtered from the upper end of the filter element downward, reducing the filtering effect of the upper end, and flushing at the same time produces A certain pressure, the pressure is difficult to buffer on the filter element, resulting in excessive extrusion on the surface of the filter element, resulting in damage to the surface of the filter element
