Description

A kind of electrically heated boiler

Technical field

Heating equipment field is the utility model is related to, more particularly to a kind of electrically heated boiler.

Background technology

Water knockout drum is that multichannel is intake to become the equipment of water outlet all the way by a container；Water collector is that water inlet all the way is logical The equipment that a container is divided into multichannel water outlet is crossed, water knockout drum is identical with water collector basic structure.Electrically heated boiler is mostly to manage at present Shape calandria, the distributive pipe of electrically heated boiler water knockout drum is identical with the sectional area of water inlet pipe, the collector pipe and outlet pipe of water collector Sectional area it is identical, cause inside distributive pipe and collector pipe that water resistance is excessive, hydraulic pressure changes greatly by force so that water in each calandria Flow velocity degree is unbalanced, each calandria temperature difference is bigger, and the utilization rate of electric energy is low, and reduce electrically heated boiler uses the longevity Life, even if the modified occurred in the market, these problems can not fundamentally be solved by remaining on.

The content of the invention

The purpose of this utility model is that to solve that water resistance is excessive in above-mentioned existing electric heating pot boiler tube, water pressure change compared with Greatly, water velocity is unbalanced in each calandria, and each calandria temperature difference is bigger, and utilization rate of electrical is low, electrically heated boiler The problems such as service life is low, and a kind of electrically heated boiler is provided.

The utility model is made up of water collector, water knockout drum and several calandrias, several calandrias with water collector, Fen Shui Device is connected；

The water collector is connected and formed with outlet pipe by collector pipe, the first conical pipe, outlet pipe and collector pipe difference position In the forward and backward both ends of the first conical pipe；

The water knockout drum is connected and formed with water inlet pipe by distributive pipe, the second conical pipe, water inlet pipe and distributive pipe difference position In the forward and backward both ends of the second conical pipe；

The sectional area of the thin mouth of first conical pipe and the sectional area ratio of thick mouth are a, 10%≤a≤70%；

The sectional area of the thin mouth of second conical pipe and the sectional area ratio of thick mouth are b, 10%≤b≤70%；

The water collector and the first conical pipe are round tube or rectangular tube；

The water knockout drum and the second conical pipe are round tube or rectangular tube；

Water collector, water knockout drum and several calandrias can form single row configuration or two-row structure or three row's structures.

Operation principle and process of the present utility model：

During work, water flows into from water inlet pipe, respectively by the second conical pipe, distributive pipe, calandria, collector pipe and the first cone Shape pipe, then discharged from effluent pipe mouth, because the sectional area ratio of the sectional area of the thin mouth of the first conical pipe and thick mouth is a, 10%≤a ≤ 70%, the sectional area of the thin mouth of the second conical pipe and the sectional area ratio of thick mouth be b, 10%≤b≤70%, so collector pipe and dividing Water velocity is smaller in water pipe, and water resistance also accordingly reduces, the change of collector pipe internal water pressure and distributive pipe internal water pressure Equal very little so that each calandria internal water flow equalization, each temperature that heats reach unanimity, and improve utilization rate of electrical and electricity adds The service life of heat boiler.

The beneficial effects of the utility model：

The utility model reduces the fault rate of electrically heated boiler, electrically heated boiler is run safety and reliability, saves the energy, Make each calandria internal water flow equalization, improve the service life of utilization rate of electrical and electrically heated boiler, reduce user and use Cost.

Embodiment

Refer to shown in Fig. 1, Fig. 2 and Fig. 3, the utility model is by 3 groups of water collector 1, water knockout drum 2 and several calandrias Into several calandrias 3 are connected with water collector 1, water knockout drum 2；

The water collector 1 is connected and formed with outlet pipe 13 by collector pipe 11, the first conical pipe 12, outlet pipe 13 and is catchmented Pipe 11 is located at the forward and backward both ends of the first conical pipe 12 respectively；

The water knockout drum 2 is connected and formed with water inlet pipe 22 by distributive pipe 21, the second conical pipe 23, water inlet pipe 22 and Fen Shui Pipe 21 is located at the forward and backward both ends of the second conical pipe 23 respectively；

The sectional area of first conical pipe, the 12 thin mouth and the sectional area ratio of thick mouth are a, 10%≤a≤70%；

The sectional area of second conical pipe, the 23 thin mouth and the sectional area ratio of thick mouth are b, 10%≤b≤70%；

The conical pipe 12 of water collector 1 and first is round tube or rectangular tube；

The conical pipe 23 of water knockout drum 2 and second is round tube or rectangular tube；

Water collector 1, water knockout drum 2 and several calandrias 3 can form single row configuration, as shown in Figure 1；
