Shunt and water replenishing boiler plate

Abstract

The invention relates to a shunt and water replenishing boiler plate which comprises a boiler plate body, a water inlet pipe, a water outlet pipe, side waterways, a hollow cavity, a heat exchange water chamber, a shunt water pipe, water channel partitions, and spoilers, wherein the heat exchange water chamber is arranged at the upper part of the boiler plate body; the water outlet pipe is arranged on one side of the boiler plate body; the heat exchange water chamber extends downwards along the boiler plate body; the side waterways are formed on the two sides of the boiler plate body; the water inlet pipe is arranged on the opposite side of the water outlet pipe and at the lower end of the boiler plate body; the oblique shunt water pipe is arranged between the water inlet pipe and the opposite side of the water inlet pipe; the water channel partitions are arranged on a side wall of the boiler plate body; and the spoilers are arranged in the heat exchange water chamber. According to the invention, the water channel partitions and the spoilers are added on the original basis to disperse a water flow, eliminate heat exchange dead angles, and prolong a flow path and heat exchange time of water; the oblique shunt water pipe overcomes the defect that gas generated by heating is not easy to exhaust; a cooling effect on the lower part of the boiler plate is improved; and heat exchange capability of the boiler plate is improved.

Description

[0001] technical field [0002] The invention relates to a cast iron boiler pan piece, in particular to a split flow and water replenishment pan piece. Background technique [0003] Cast iron boilers are popular because of their corrosion resistance and long service life. The lower part of the traditional cast iron boiler adopts an annular water jacket structure, and the flame burns in the hollow cavity surrounded by the annular water jacket, forming a kind of water-in-fire The structure, the way the water inside the pot sheet absorbs the heat of the flame is radiation heat exchange, but the amount of air required for the flame combustion of this water-in-fire system is often insufficient, resulting in incomplete combustion of the flame, and the lower part of the hollow cavity is horizontal Tube, the gas generated by heating in the tube is not easy to discharge, which reduces the radiation heat transfer efficiency. The inside of this pot is equipped with round columns and so...

Problems solved by technology

[0005] The beneficial effects of the present invention are: the present invention adds water channel partitions and spoilers on the basis of the original, the water flow can be dispersed when it flows, the heat exchange dead zone is eliminated, the heat exchange surface is increased, and the water flow is prolonged. The process and heat exchange time improve the heat exchange efficiency of the pot piece. The invention also adds a diversion water pipe with a slope of 0~15°, which increases the heat exchange area and overcomes the horizontal water pipe at the lower part of the incomplete water-in-fire structure. Due to the defect that the gas generated by heating is not easy to discharge, it enhances the cooling effect on the lower part of the pot, improves the water circulation, and eliminates the dead zone of water flow. The gap between them also becomes the entrance of the air required for combustion, which makes the flame burn completely and improves the heat exchange capacity of the pot pieces.
