Inertial separation and dust removing device on catering stove

Abstract

The invention relates to an inertial separation and dust removing device on a catering stove. The inertial separation and dust removing device comprises a shell, a smoke inlet pipe, a smoke outlet pipe, separation plates and a filtering net, wherein the smoke inlet pipe is arranged on the lower part of the shell; the smoke outlet pipe is arranged on the upper part of the shell. The inertial separation and dust removing device is characterized in that a plurality of separation plates which are staggered relatively are arranged on opposite inner walls of the shell, and are provided with circular arcs, and concave surfaces of the circular arcs are arranged towards the smoke inlet pipe; the filtering net is closed on a lower channel of the smoke outlet pipe. According to the inertial separation and dust removing device on the catering stove, the plurality of separation plates with circular arcs, which are staggered relatively, are arranged on the opposite inner walls of the shell; when dust-containing smoke enters the separation plates, the flowing direction is changed abruptly; the mass difference of the smoke and ash grains is great, the ash grains are subjected to an inertia force and the movement track of the ash grains are deviated from a flow line of a smoke flow, so that the ash grains are separated from the smoke flow and fall down to corners of the dust removing device to realize the dust removing aim. The inertial separation and dust removing device on the catering stove has the advantages of simple structure, convenience in production, good dust removing effect and low cost.

Description

technical field [0001] The invention relates to a dust removal device, in particular to an inertial separation dust removal device on a catering stove, and belongs to the technical field of environmental protection. Background technique [0002] At present, stoves are widely used in small and medium-sized restaurants, canteens, and open-air dining spots, and most of the fuel is still coal-based. After the coal is burned by the furnace, the non-flammable solid residues produced by it form cinder, while the solid combustion residues brought out from the furnace by the flue gas form ash, and a part of the ash particles with larger particle size is deposited in the flue or thermally floated. On the inner surface of the chimney, a part of the ash particles are discharged into the atmosphere with the flue gas through the chimney. Since dining stoves are generally small in size, the setting height of the chimney cannot be too high, especially for open-air dining stoves, which can ...

AI Technical Summary

Problems solved by technology

Since the catering stoves are generally small in size, the height of the chimney cannot be set too high, especially the open-air catering stoves, which can even be reached by hand. to the atmospheric environment and people's health

In order to reduce the environmental pollution of catering stoves, people have adopted various dust removal methods to suppress this, the most typical of which is a wet dust removal device, which passes the smoke and dust generated in the stove through a water storage tank to make it fully contact with the water surface. , so that the ash particles in the flue gas are separated from the flue gas. This device can effectively remove the ash particles in the flue gas, but there are certain defects: 1. The structure is relatively complicated, and certain settings must be provided to meet the requirements of the flue gas. Full contact between gas and water; 2. From the perspective of cost performance, generally the flue gas travels horizontally to increase the contact area between the flue gas and the water surface, thus increasing the lateral volume of the stove; 3. The water storage tank must be made of stainless steel Otherwise, it is easy to rust and increase the manufacturing cost
