Straw incineration haze control device

Abstract

The invention discloses a straw incineration haze control device. The problem that smoke particulate matter emission of an existing straw combustion treatment device exceeds the standard is mainly solved. The device is characterized by further comprising a filter element, a waste gas fine filter cavity, an air velocity sensor, a double-tangential gas inlet cavity, a centrifugal waste gas separation cavity, a spiral gas inlet type shell, a weight sensor and a dust collection cavity; a spiral air inlet channel is arranged in the spiral air inlet type shell, and air enters from an air inlet of the spiral air inlet type shell; a blast chamber and a blast impeller are mounted in a chimney buckling cover, and the filter element is mounted at the rear part of the chimney buckling cover; the waste gas fine filter cavity is connected with the filter element, and the air velocity sensor is mounted in the waste gas fine filter cavity; after being connected with the waste gas fine filter cavity and the centrifugal waste gas separating cavity, the double-tangential gas inlet cavity is integrally sleeved in the spiral gas inlet type shell; and the double-tangential gas inlet cavity is connected with the waste gas fine filter cavity, and the lower part of the double-tangential gas inlet cavity is connected with the centrifugal waste gas separation cavity to jointly form a separation section. The device has the characteristics of thorough waste gas treatment and sufficient combustion.

Description

technical field [0001] The invention relates to a device applied in the fields of environmental protection, waste gas treatment and the like. Background technique [0002] Straw, called stalks in ancient times, also known as stalk grass, refers to the remaining stems and leaves of grass crops such as rice, wheat, and corn after threshing, and is commonly called straw. Farmers have a long history of using straw, but in the past, the level of agriculture was low, the development of agriculture was underdeveloped, and the output of straw was low. With the development of modern agricultural production, grain output has increased significantly, and the amount of straw has also increased. Coupled with the promotion of energy conservation and emission reduction policies, and the popularization of liquefied gas, there are a lot of straw in rural areas, but the cost of straw treatment is too high. high. Affected by various factors, farmers are currently less motivated to collect st...

AI Technical Summary

Problems solved by technology

At present, affected by various factors, farmers are less motivated to collect straw, and they basically use incineration for disposal, resulting in a large amount of exhaust gas, which in turn forms smog, which greatly affects the visibility of cities, countryside, airports, highways and other places.

Although a variety of straw incineration devices have appeared on the market, these existing devices generally have the problems of incomplete waste gas treatment and insufficient combustion to generate a large amount of smoke and dust
