Tail gas energy recycling combustion boiler

Abstract

The invention belongs to the technical field of combustion boilers, and discloses a tail gas energy recycling combustion boiler. The tail gas energy recycling combustion boiler comprises a combustionboiler body, the combustion boiler body comprises a combustion box, a preheating box and a water pump, a combustor and a water tank are arranged in the combustion box, a water inlet is formed in one side of the preheating box, the water inlet is connected with the water pump through a water pipe, a filtering device is arranged in the water pipe, an air inlet is formed in one side of the preheatingbox, an exhaust port is formed in the upper end of the preheating box, one side of the combustion box is provided with a control panel and an air outlet, the air outlet is connected with the air inlet through an air guide pipe, the preheating box is connected with the combustion box through the water pipe, the water pipe is provided with a valve, and one side of the combustion box is provided with a water outlet. By means of the filtering device in the water pipe, larger impurities in water can be filtered so that the impurities cannot enter the preheating box, and then the combustion rate isprevented from being influenced; and the connection through the air guide pipe is achieved so that waste heat in combustion tail gas can be better utilized to pre-heat the water.

Description

technical field [0001] The invention relates to a combustion boiler, in particular to a combustion boiler for reusing tail gas energy, and belongs to the technical field of combustion boilers. Background technique [0002] At present, with the continuous development of society and the development of industry, people directly discharge some energy-available tail gas, which causes energy waste and cannot effectively improve energy utilization, which is not conducive to energy conservation and production efficiency. Improvement, and when adding water to the water tank, due to people's inattentiveness, the water constantly overflows from the water tank, which seriously wastes water resources. [0003] At the same time, the traditional combustion boiler is a device for heating water. After the fuel burner in the fuel boiler finishes heating the water, it will form flue gas that still has a relatively high temperature. Most manufacturers directly discharge this part of flue gas ,...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention overcomes the existing defects, and provides a combustion boiler for reusing tail gas energy. Through the filter device in the water pipe, it is beneficial to filter the relatively large impurities in the water, so that the impurities cannot enter the preheating box, thereby affecting Combustion rate, through the connection of the air duct, the waste heat in the combustion exhaust gas can be better used to preheat the water. The water level detection device is beneficial to detect the change of the water level in the preheating box. Through the blower and the bell mouth, it can be better. The water tank is evenly heated, which can effectively solve the problems in the background technology
