Abstract

The utility model discloses a vertical upper water return energy-saving water heating boiler which is formed by the upstanding combination of an upper segment 1 and a lower segment 2. The utility model is characterized in that an inner barrel 3 in the upper segment 1 and an inner barrel in the lower segment 2 are both provided with heating pipes 5, 6 with the same number; the upper segment 1 and the lower segment 2 are divided by a ring-shaped iron plate 7 and are communicated by a reverse communicating pipe 8; a water return valve 11 is arranged at the lower part of the upper segment 1; a water outlet 12 is arranged at the upper end of the lower segment 2. The heat carrier, water, firstly returns to the upper segment and is conducted into the lower segment 2 for being heated again by the reverse communicating pipe 8 after firstly heated; thereby, the temperature around a boiler chamber is enhanced; the fuel is sufficiently burnt so as to achieve the goal of saving energy.

Description

The vertical backwater energy-saving hot water boiler of going up

The utility model relates to a kind of boiler, relates in particular to backwater energy-saving hot water boiler on a kind of vertical type.

Existing hot-water boiler, being the heating system backwater enters in the boiler through boiler backwater interface bottom, heating is after boiler delivery port is topmost sent into heating system, this usual manner has following shortcoming: bottom temp is on the low side during (1) boiler operatiopn, and the combustion chamber is just in the bottom, the abundant burning of low excessively temperature effect fuel; During flue gas process body of heater upper strata, because the boiler TNE UPPER SEA TEMPERATURE is higher relatively, have a narrow range of temperature, the heat absorption condition is bad, and heat can not be fully utilized; (2) the overall heating surface area of straight-line boiler is little, flue outlet temperature height, and heat waste is big.

The purpose of this utility model just provides a kind of vertical type, backwater in the body of heater upper end, can make the energy-saving hot-water boiler of thermophore post bake in the stove.

For achieving the above object, the technical solution of the utility model is: this boiler is arranged for two joints are upright up and down, every joint inwall is equipped with the heat pipe of equal number, outer wall is established a reverse communicating pipe, make on the boiler the reverse importing boiler of the joint heated hot water bottom of joint down, through after the post bake again by under save the top and send.

Employing the utility model has the advantages that: 1. increased the heating surface area in the body of heater, improved heat utilization efficiency; 2. go up backwater and make thermophore post bake in the stove, improve the combustion chamber environment temperature, fuel can fully burn, and reduces consuming, and reaches the purpose of energy savings; 3. the utility model technology simple structure compactness does not need air blast air inducing, does not have noise pollution.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is that master of the present utility model looks and partly cuts open figure;

Fig. 2 is a rearview of the present utility model.

Shown in Figure 2 as Fig. 1, boiler body is uprightly combined by last joint 1 and following joint 2, for increasing heating surface area, in the last joint 13 times joints 2 of tube in tube 4 be equipped with the identical heat pipe of quantity 5 and 6, two joint junctions cut off with annular iron plate 7, make water layer separately, have at as shown in Figure 2 boiler body rear side to make on the boiler joint 1 a reverse communicating pipe 8 and save 2 down and communicate.

The utility model is like this work: at first close blowoff valve 9 and open air bleeding valve 10 fill with thermophore-water in system and in the boiler, close air bleeding valve 10 igniting operations, system's backwater at first enters through the bottom of last joint 1 water return outlet 11 and saves 1 on the boiler, after the first heating of tube 3 and last joint heat pipe 5 in the boiler, import joint 2 down through reverse communicating pipe 8 by last joint 1 again, save down 2 in send into the heating system heat radiation by the delivery port 12 that saves 2 upper ends down again after the heating in tube 4 and the heat pipe 6 and heat.
