Abstract
The utility model belongs to the technical field of architectural heat energy power, particularly a constant ratio constant pressure steam jet pump with a changeable spray nozzle. The utility model is mainly composed of a water suction chamber (3), a catch tank (5), a pressure-expanding pipe (6), and a spray nozzle (1) arranged between a steam pipe (2) and a water supply pipe (8), wherein, the spray nozzle (1) can be screwed down from the steam pipe (2), and a manual and electric control valve arranged on the side wall of the water suction chamber (3) can regulate the pressure in the water suction chamber (3). The utility model has the advantages that vibration and the noise generated during the operation of the jet pump are relieved, the condition that the existing jet pump is difficult to start is improved, the regulating range of heat supply is enlarged, and the cost is reduced. Thereby, the economical benefit is raised.
Description
The utility model relates to a kind of constant proportion level pressure variable-nozzle vapor pump, belongs to building heat-energy power technology field.
Be that traditional approach that heating agent reaches hot water heating is to be the heating system that main body is formed with heat exchanger, water pump with steam.Heat exchanger is exchanged into the needed hot water of heating, heating agent with steam thermal energy; Water pump plays the effect of pressurizing circulation.And the vapor pump in the steam jet heating system can play the double action of heat exchange pressurizing circulation.But because that the jet pump of this system exists running noises is big and be accompanied by vibration, deficiency such as start difficulty and the heat regulation scope of spraying is less causes the development of this technology to be affected.
The purpose of this utility model is exactly at the deficiencies in the prior art part, and noise when a kind of the operation is provided, vibration be little, start easily and increase the constant proportion level pressure variable-nozzle vapor pump that sprays the heat regulation scope.
The purpose of this utility model realizes by following measure:
The utility model mainly is made up of the nozzle 1, suction chamber 3, catch tank 5, diffuser pipe 6 four parts that are located between steam tube 2 and the water pipe 8.Its middle steam tube 2 front ends are provided with nozzle 1, the nozzle 1 outer suction chamber 3 that is provided with, suction chamber 3 sidewalls are provided with draining steam discharge short tube 11 and the manual or electric control valve 14 that is located on the draining steam discharge short tube 11, suction chamber 3 belows are provided with return pipe 9, nozzle 1 front end is established catch tank inlet 4 and is connected with catch tank 5, and catch tank 5 is connected with diffuser pipe 6, and diffuser pipe 6 is connected with water pipe 8, the left side is provided with pressure release short tube 12 above condensing diffuser pipe outer wall 7, and the right side is provided with steam short tube 13.Nozzle 11 and steam tube 2 can screw off from steam tube 2 for screw is connected.
Working condition when advantage of the present utility model is the operation of improvement system, alleviated noise and the vibration of jet pump when work greatly, the steam jet pump startup is easy, the heat supply regulation range enlarges, simultaneously, take system to compare with the heat exchanger recycle pump of routine and can save the original equipment cost and the operation electricity charge widely, reduce device maintenance work amount, improve water of condensation heat recovery rate.
Description of drawings is as follows:
Fig. 1 is a structural drawing of the present utility model;
Fig. 2 is the user mode figure of the utility model in system.
Be described in further detail by embodiment below in conjunction with accompanying drawing:
The utility model mainly is made up of the nozzle 1, suction chamber 3, catch tank 5 and diffuser pipe 6 four parts that are located between steam tube 2 and the water pipe 8, is provided with nozzle 1 at steam tube 2 front ends, and nozzle 1 is connected for screw with steam tube 2.The nozzle 1 outer suction chamber 3 that is provided with, nozzle 1 front end is provided with catch tank inlet 4 and is connected with catch tank 5, catch tank 5 is connected with diffuser pipe 6, diffuser pipe 6 is connected with water pipe 8, being provided with draining steam discharge short tube 11 and the manual or electric control valve 14 that is located on the draining steam discharge short tube 11 on suction chamber 3 sidewalls, below suction chamber 3, be provided with return pipe 9, be provided with pressure release short tube 12 at condensing diffuser pipe outer wall 7 upper left sides, the right side is provided with steam short tube 13, is provided with dividing plate 10 between catch tank 5 main diffuser pipes 6.
Fig. 2 is certain unit heat supply flow chart, 23000 meters of 4T/H steam boiler supplies
2The heating load of area and health hot water heating load.Heating system adopts constant proportion level pressure variable-nozzle vapor pump, and jet pump adopts the D150 type, basic orifice size d=35mm, the heating heating agent is 95 ℃/70 ℃, 15 meters of the drag overalls of heating system, design work vapor pressure 0.6MPa sprays 18 meters of lift of pump.70 ℃ of backwater that return pipe is returned heating system are introduced the jet pump suction chamber, working steam draws steam by pipe and goes into jet pump, the spout place that acts on by nozzle forms supersonic airstream, carry out the transformation of energy of carbonated drink at catch tank and diffuser pipe, Heating Medium is heated to 95 ℃ by 70 ℃, and the required circulating pressure of the system that is pressurized to, because this constant proportion level pressure modulating valve, method with manual tune makes the pressure constant proportion of suction chamber press in working steam, make system often be in stable operating mode, avoided producing the operating mode of noise and vibration.
Constant proportion level pressure variable-nozzle steam jet heating system and conventional heat exchanger recycle pump heating system are 2.0MW for the heating heat load, and heating area is 23000 meters
2Same case under, do a concise and to the point tabulation analysis below, obviously adopt constant proportion level pressure variable-nozzle vapor pump can bring very big economic effect.
