Steam boiler with pressure blowdown thorough-cleaning function

Abstract

The invention discloses a steam boiler with a pressure blowdown thorough-cleaning function. The steam boiler with the pressure blowdown thorough-cleaning function comprises a furnace body and a waterdischarging pipe arranged at the bottom of the furnace body, wherein the water discharging pipe is a rigid pipeline, pipe diameters of all sections of the water discharging pipe are equal, the water discharging pipe communicates with a thick pipe of which the pipe diameter is larger than that of the water discharging pipe, a vertical pipe communicates with the side wall of the water discharging pipe, a piston plate is connected in the vertical pipe in a sealing and sliding mode, a flat and hollow heat conduction box is fixedly connected to the piston plate through a connecting rod, and one endof the heat conduction box communicates with the water discharging pipe through a first hose. The steam boiler with the pressure blowdown thorough-cleaning function has the advantages that the waterpressure is large in a boiler water discharging initial stage, the water pressure in the water discharging pipe enables the heat conduction box to move upwards to make contact with a fluid pipe, and arotary mechanism is driven to rotate and compress a torsion spring; and when the water pressure in the boiler is reduced, the torsion spring drives a knocking device to rotate reversely, when reverserotation of the knocking device is accelerated, a limiting block is separated from a limiting groove under the acceleration action of the knocking device so that a collision block impacts the furnacebody, then residual dirt in the furnace body can be knocked down, and the effect that the dirt in the boiler is treated more thoroughly is achieved.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a thoroughly clean steam boiler with pressure sewage discharge. Background technique [0002] Pressurized steam boilers have to discharge sewage under pressure at least once a day, and the discharged high-temperature water takes away a lot of heat. A few years ago, enterprises did not care about the large amount of energy carried in the discharged high-temperature water. However, under the current general environment, the production cost of enterprises needs to be controlled from all aspects; more and more enterprises will reuse these high-temperature water when the boiler is drained, and the utilization method is mostly connected to the drain of the boiler body. The power generation device or heat exchange device also brought about a big problem: when the boiler is discharging sewage under pressure, there is only obvious pressure in the furnace body at the initial stage of water...

Problems solved by technology

However, under the current general environment, the production cost of enterprises needs to be controlled from all aspects; more and more enterprises will reuse these high-temperature water when the boiler is drained, and the utilization method is mostly connected to the drain of the boiler body. The power generation device or heat exchange device also brought about a big problem: when the boiler is discharging sewage under pressure, there is only obvious pressure in the furnace body at the initial stage of water discharge, which can make the water flow faster and wash away the furnace body If the heat recovery device is not installed in the early stage, the remaining dirt can be manually removed from the drain, but now after the heat recovery device is installed, different equipment is installed at the drain, and it cannot be manually removed from the drain Therefore, it is particularly important to apply for a device that can discharge the dirt in the boiler during the drainage process
