Abstract

A hot water boiler with a preheating water tank comprises a boiler body, the preheating water tank and a dust collection box. The boiler body is connected with the preheating water tank through a smoke pipe, and the preheating water tank is connected with the dust collection box through a gas conveying pipe. A hot water outlet pipe is arranged at the upper end of the left side of the boiler body, and an air heater and an air blower are arranged at the lower end of the left side of the boiler body. A water cooling wall pipe, a fire grate, an air inlet, a slag outlet and a waste slag chamber are arranged in the boiler body, and the left end of the water cooling wall pipe is connected with the hot water outlet pipe. A water inlet pipe is arranged on the right side of the top end of the preheating water tank and connected with a preheating water pipe inside the preheating water tank, the pipe orifice in the other end of the preheating water pipe is connected with the water cooling wall pipe inside the boiler body through a connecting pipe, and a denitration pool is arranged at the inner bottom end of the preheating water tank. According to the hot water boiler, waste heat in waste gas of the boiler can be used for preheating cold water in the preheating water pipe of the preheating water tank, so that the heating efficiency is improved, and the energy source utilization rate is improved.

Description

Summary of the invention

the object of this invention is to provide a kind of hot-water boiler with preheating water tank; device preheating water tank; the waste heat in boiler waste gas can be utilized to be the preheating cold water in preheating water tank's preheating water pipe; improve the efficiency of heating surface; improve the utilization rate of the energy; and built-in denitration pond, dirt pocket, can effective purifying exhaust air, protection of the environment, decreasing pollution.

object of the present invention is achieved through the following technical solutions:

with a preheating water tank's hot-water boiler, comprise body of heater, preheating water tank, dust cleaning case, described body of heater connects preheating water tank by smoke-fire-tube, and described water tank connects dust cleaning case by appendix; Device for upper end hot water outlet pipe on the left of described body of heater, end device air heater, air blast under left side, described furnace interior device water screen tube, fire grate, air inlet, slag-drip opening, waste slag chamber, described water screen tube left end connects hot water outlet pipe; Described preheating water tank top right-hand unit water inlet pipe, connect the inner preheating water pipe of preheating water tank, the described preheating water pipe other end mouth of pipe connects furnace interior water screen tube by tube connector, and described preheating water tank's inner bottom arranges denitration pond; Described dust cleaning case inside is arranged through the first cyclone dust collectors, the second cyclone dust collectors, the 3rd cyclone dust collectors that pipeline connects, and on the right side of dust cleaning case, upper end arranges blast pipe.

described water screen tube, preheating water pipe are the snake bend with multiple back bending place.

device micro pump on tube connector between described preheating water pipe and water screen tube.

described a kind of hot-water boiler with preheating water tank; after boiler operatiopn, generation waste gas is the preheating cold water in preheating water tank in preheating water pipe, and the cold water then in preheating water pipe enters the heating of boiler internal water screen tube; improve the efficiency of heating surface, save the burning energy; also arrange denitration pond bottom preheating water tank, can remove the nitre in waste gas, the flue gas after denitration enters in dirt pocket; after multiple cyclone dust collectors dedusting; be expelled in air, decrease pollution, protect environment.

beneficial effect of the present invention: a kind of hot-water boiler with preheating water tank of the present invention; device preheating water tank; the waste heat in boiler waste gas can be utilized to be the preheating cold water in preheating water tank's preheating water pipe; improve the utilization rate of the energy; and built-in denitration pond, dirt pocket; can effective purifying exhaust air, protection of the environment, decreasing pollution.
