TH19685A3 - A prototype high-heat furnace for extracting silica from rice husks. - Google Patents

Abstract

A summary of the invention, which appears on the advertisement page, ReadFile:The prototype high-heat furnace for extracting silica from rice husks is a furnace consisting of a cold-rolled steel plate furnace with digitally programmable temperature control. Controlled and programmable automatically, there are spring heaters, ceramic pipes on both sides of the stove wall, there is a safety system to prevent fire and automatic operation. There is a stainless steel tray compartment. The fume extraction system goes back to the smoke incinerator, which is located on the top of the rice husk incinerator, causing no toxic fumes to be released into the environment. The rice husk can be packed for burning up to 5-10 kg at the same time.

Claims (1)

Claims (all) which will not appear on the classifieds page:------19/08/2021------(OCR) 1.Prototype high temperature furnace for extracting silica from Rice husk consists of a kiln (1) made of cold-rolled steel sheet in a square shape at the front with an opening-closing lid (2) inside the kiln (3) there is a shelf rack (4) for placing the rice husk packing tray or material tray. For incinerating the inner wall of the furnace (3) and the opening-closing lid (2), install a heat-insulating layer (5), at the top there is a smoke pipe (12), which has a digital programmable temperature control. Controllable and programmable automatically, there are spring heaters, ceramic pipes on both sides of the furnace wall, safety system, leak proof and automatic operation, smoke removal system (9) wear down. On the smoke pipe (12) to bring the smoke generated from the combustion chamber into the re-burning process, it is characterized by a heat-insulating layer (5), consisting of a heating coil (7) embedded. Into the refractory brick (6) and cover the heat insulation layer (5) at the wall inside the furnace (3) with stainless steel sheets (8) Smoke removal system (9) has an external appearance as a chimney or pipe From stainless steel, high heat resistance consists of a heater (Heater) hood pipe and heat-resistant insulation worn on the smoke pipe (12 ) to bring the smoke generated by the combustion in the incinerator (3) into the re-burning process by allowing the smoke to flow through the inlet and outlet pipes when treated by the external tribute to the internal insulating cover consisting of windings. Provides heat that can be heated up to 1000 degrees Celsius. Controlled from the control panel. Smoke removal system (10) is attached to the side of the furnace. The furnace has a digital control and programmable temperature control. Automatic from the furnace operation panel (11) to set the temperature with all 3 steps, which is Step 1, turn on the oven switch to the temperature up to 130-140 degrees Celsius and maintain the temperature for 50-70 minutes and then adjust the temperature to step 2 at a temperature of 280-320 degrees Celsius and then maintain the temperature for 25-40 minutes and adjust the temperature to step 3, the temperature is 750-850 degrees Celsius Maintain this temperature for 90-130 minutes-------------- 1. The prototype high-heat furnace for extracting silica from rice husk consists of a furnace (1) made of cold-rolled steel sheet, rectangular shape with front opening-closing lid (2), inside the furnace (3) with shelves. A grate (4) for placing a tray containing rice husks or a material tray for incinerating the inner wall of the furnace (3) and an opening-closing lid (2). Install a heat-resistant layer (5) at the top with a smoke pipe. (6) It has digital programmable temperature control and can be programmed automatically. There are spring heaters with ceramic pipes on both sides of the furnace wall, there is a safety system to prevent fire and work. The automatic type has a smoke removal system (9), put on the smoke pipe (6) to bring the smoke generated from the combustion chamber into the re-burning process. It has a unique feature that is the heat insulating layer (5). It consists of installing a heating coil embedded in the refractory brick (6) and (7) and covering the heat-insulating layer (5) at the wall in the furnace (3) with stainless steel plate (8). The smoke (9) has an external appearance as a chimney or pipe made of high-temperature stainless steel consisting of a heater (Heater), a hood pipe and heat-resistant insulation worn on the smoke pipe (6). To bring the smoke from the combustion in the incinerator (3) into the re-burning process by letting the smoke flow. Through the inlet and outlet pipes, when treated externally to a tribute to the insulating cover, the internal consists of a heating coil that can heat up to 1000 degrees Celsius, the use is used at 800 degrees Celsius with control. Working from the control panel, the smoke removal system (10) attached to the side of the incinerator causes the combustion of smoke released from the biomass transition phase at 200-400 °C. Smoke that has both color and smell is the result of incomplete combustion. The smoke drifting into the smoke removal system will burn the smoke again to complete combustion before being released into the air. Or the smoke that will come out will not have smoke and smell while burning biomass.
