High-efficiency double-vertical-pot gas-liquid reverse-flow exchange mechanism

Abstract

The invention discloses a high-efficiency double-vertical-pot gas-liquid reverse-flow exchange mechanism, and relates to technical structures that according to the relation separation between pots and a furnace, the pots are managed independently, the furnace is managed independently, the pots and the furnace fulfill duties respectively, and the optimal efficiency is achieved. The mechanism comprises a high-temperature pot and a low-temperature pot which are separated in order to improve efficiency of the pots. The lower portion of the high-temperature pot is movably connected with a flame releasing opening of a furnace, the lower portion of the low-temperature pot is connected with a gas-dust chamber, the gas-dust chamber is connected with a discharge pipe, the upper portion of the high-temperature pot is fixedly connected with the upper portion of the low-temperature pot in a gas-communication and liquid-communication mode, an inlet for cold liquid is limited to be a smoke outlet, and a high-temperature flame gas inlet is limited to be a hot water or steam outlet. For combination of the pots and the furnace, an assembly latch and an eccentric wheel pull buckle are combined, in this way, rapid connection and rapid separation can be achieved, boiler failures can be rapidly removed, and recovering of normal operation is rapid. The defects that for all kinds of present fuel combustion boilers, due to failures, the boilers stop working and quench, and then time is delayed, and dirt at dead corners inside the boilers is difficult to clear away are overcome, more importantly, liquid-gas reverse-flow exchange is adopted so that the highest exchange efficiency can be achieved, the discharging temperature of smoke is higher than the injection temperature of the liquid by about 20 DEG C, and the technology achieves the lowest discharging temperature of boiler smoke at the present.

Description

technical field

[0001] The invention relates to a high-efficiency double-vertical double-pot gas-liquid countercurrent exchange mechanism. Background technique

[0002] Human beings use a lot of heat, and they all rely on boilers to produce heat for human beings. At present, the most difficult problem in the field of boiler technology is that thermal efficiency cannot be improved, boiler failure can not be solved immediately, energy in flue gas cannot be recovered, energy waste still exists, and pollutant emissions increase, etc. defect. The present invention overcomes the above-mentioned difficult technology for boilers at present, and is designed to be multifunctional. Cool liquid is input into gas-liquid countercurrent exchange in the lowest temperature zone, liquid is output to the highest point of gas, and hot gas is exchanged to the lowest point of liquid to be discharged. , The design of the heat exchange pot is two garden-type vertical pots, one is a high-temperatur...
