Smoke-free type vertical coal-saving machine special for industrial boiler

Abstract

The invention discloses a smoke-free type vertical coal-saving machine special for an industrial boiler. The smoke-free type vertical coal-saving machine comprises a machine base, a fixing device is mounted above the machine base, a water storage tank is mounted on the top of the fixing device, a hot water pipe is arranged at one end of the water storage tank, a water tank cover is arranged above the water storage tank, a water inlet pipe is arranged on the water tank cover, a water storage tank and a water collection tank are symmetrically arranged at the position, on the two sides of the fixing device, of the machine base, the outer side of the fixing device is wound by a metal guide pipe, the two ends of the metal guide pipe are connected with the water collection tank and the water storage tank, and a smoke purification device is arranged at the end, close to the water storage tank, of the machine base. Efficient utilization of smoke heat and smoke automatic filtering purification functions are achieved, and the beneficial effects that a heat preservation layer is arranged, heat losses are small, a heat insulation layer is arranged, smoke heat losses are small, the smoke heat utilization rate is high, potential safety hazards do not exist, slag-free particle filtering is carried out on a smoke inlet, and therefore a flue cannot be blocked; coal is completely combusted, the resource utilization rate is high, and the smoke is automatically purified and exhausted to the air are achieved.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for boilers, in particular to a special smokeless vertical coal economizer for industrial boilers. Background technique [0002] Most of the current industrial boilers adopt the direct exhaust type, and the exhaust smoke of industrial boilers is mostly discharged directly through the chimney, which not only wastes a lot of heat, but also pollutes the environment with a lot of smoke and dust in the flue gas. With the rise of coal prices and the national energy conservation and emission reduction With the improvement of requirements, the research and development of economizers for industrial boilers has received extensive attention from industry research and design personnel. [0003] The existing economizer is mainly composed of a shell, a curved flue and a twisted cast pipe inside. The flue is connected to the boiler flue. The heated water is added to the boiler to achieve the purpose...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a special smokeless vertical economizer for industrial boilers, which can solve the problems of existing economizers such as high heat loss without heat insulation layer and high heat loss of flue gas without heat insulation layer. , low heat utilization rate of flue gas, exposed equipment is easy to burn the staff, there are potential safety hazards, the flue gas inlet is not filtered, coal slag particles enter and block the flue, the waste of coal incomplete combustion is large, and the flue gas is directly discharged into the air and causes great environmental pollution. , can realize efficient utilization of flue gas heat and automatic flue gas filtration and purification functions, with small heat loss when setting insulation layer, low heat loss of flue gas when setting heat insulation layer, high utilization rate of flue gas heat, no safety hazard, and flue gas inlet It has the advantages of filtering without coal slag particles entering and blocking the flue, high resource utilization rate of complete coal combustion, and automatic purification of flue gas into the air.
